Refurbishment in a life cycle perspective for an eco-oriented public planning

Abstract

 

The building stock refurbishment is achieving more and more energy savings goals, but the impacts associated with the building activities are not always considered: i.e. the waste’ production of construction and demolition as well as from addiction of high-tech materials. This paper describes the extension to the urban scale an already applied and developed procedure for individual buildings, which aims to maximizing the exploitation of the existing building components and materials, in a life cycle perspective. The outcome is a tool by which a first survey can be carried on an urban area to guide further refurbishment process.

From the energy performance certificate to the building renovation passport

Abstract

 

The energy performance certificate is currently one of the main tools for mapping the energy performance of buildings. However, the recent analyses conducted on the impact of EPC on the EU construction market level have highlighted a lack of confidence in the tool, considered by most as a mere regulatory obligation with low impact on the real quality of the built environment. The objective of the document is to frame and define a new tool called building passport for the energy redevelopment of buildings, offering an overview of current European initiatives highlighting the principles, potential impacts on the market and the main obstacles.

Sustainability and innovation in constructions intended for emergency housing

Abstract

 

The research aims to give a response to the emergency housing that occurs after catastrophic events by proposing a low-cost solution through innovative constructions. The illustrated solution – based on a living module composed by four adjacent sections that can be connected to each other or to new ones – combines the concepts of minimum and affordability with those of efficiency and sustainability.

Life cycle analysis and planning in the renovation process of public housing

Abstract

 

The paper presents some preliminary outcomes of the European funded research project named Pro-GET-onE, in particular life cycle analysis and planning applied to the refurbishment of existing public housing. The project regards the renovation of residential buildings through seimic rehabilitation and energy retrofitting. LCA and LCC analyses are carried out to compare different solutions and evaluate the impact of renovation in relation to demolition and reconstruction. The first results of a pilot building in Athens prove the economic and environmental convenience of the renovation approach.

A smart village model for the Italian coastal territory

Abstract

 

Small municipalities, if taken individually, have difficulty in implementing energy policy and sustainable projects (economic, environmental and social), because they do not have sufficient financial and human resources. The idea is to regenerate a territorial area following the principles of innovation and sustainable development, that is the applicability of the concept of Smart Villages on an entire “small” territory with homogenous characteristics (similar morphology, coastal village or bordering the coast, tourism as the main business, ect.) and with several villages with less of 3000 habitants; this is the “Golfo dell’Isola” in Liguria.

Engineering and management of information modeling requirements

Abstract

 

The presented document discusses the application of Requirements Engineering and Management methods and techniques for identification and traceability of requirements to support Information Modelling during the design process. Errors and ambiguities are generally found during the briefing phase. Pre-occupancy simulation on the information model verifies the interactions among future users to meet the intended use. The information model allows to monitor the gap between expected and actual quality throughout the design process.

The renovation of the building stock in Europe: an essential opportunity to store carbon in buildings

Abstract

 

In the next decades, a large share of residential buildings in EU-28 is expected to be renovated and a large amount of insulation materials will be produced. Bio-based materials are a valuable alternative to insulate the buildings and the biogenic carbon can be stored in the built environment for a relative long time. This article investigates the effect of massively storing carbon in construction when different bio-based materials are used. The results show that only bio-based material with a very fast regrowth, e.g. straw, have an effective potential in removing carbon from the air in a very short-time, and can contribute to achieve the Paris Agreement goals by 2050.

Information modeling for the monitoring of existing buildings’ indoor comfort

Abstract

 

BEMS (Building Energy Management System) and BACS (Building Automation and Control System) make available a high quantity of data on consumptions, indoor and outdoor conditions and users’ profiles of a buildind that can drive the choice of energy retrofit interventions. Moreover, the current developments in the digitalization of the building process, are leading the diffusion of BIM methods and tools which can provide a valid support to manage all data and information for the retrofit process. The paper is focused on the efficient integration of these systems.

Mutations of a modern habitat. The district of Derb Jdid in Casablanca

Abstract

 

The debate on the habitat in the period of the CIAM IX of 1953 proposes a paradigm shift in relation to the recent past: overcoming “critically” the universalising approach in the conception of mass housing to focus on the analysis of the relationships and hybridisation between European modernity and the local specificities in North African countries.
This contribution proposes a study on the district of Derb Jdid in Casablanca, designed by the architect Elie Azagury. The continuous mutation of the habitat developed from local community settlements enriches Derb Jdid with a paradigmatic value in relation to the question concerning the transformation dynamics of residential areas in the contemporary city.

The Pantheon of Gaetano Cima in Guasila. Interdisciplinary studies for its structural conservation

Abstract

 

The paper presents the integrated results obtained from an interdisciplinary protocol of research designed for assessing the structural safety and state of conservation of the monument. Starting from the archival researches about the construction history and the restoration works, 3D geometric surveys, diagnostic as well as geognostic investigations have been performed for implementing the knowledge of the structures, characterised by several static problems since its construction. Overall the study has individuated the level of static efficiency of the basilic and the causes of its prolonged decay, stating a base point for the definition of future interventions.

Architecture in the second half of the 20th century: forms of expression and the “environmental issue”

Abstract

 

Numerous architectural works from the second half of the 20th century, having a recognized cultural value, turn out to be quite problematic when observed in the scope of today’s unavoidable principle of environmental responsibility. Though representing an energy “issue”, they are at the same time a “high-level witness” in the context of architecture, whose original form of expression, language, and perception must be preserved as intact as possible. This paper critically presents three interventions on architectures in Turin by Domenico Morelli that allow us to make a series of general observations concerning the relationship between preservation and adaptation of works from the second half of the 20th century.

Experimental apparatus for the determination of thermal conductivity and humidity in building materials by means of electrical permittivity measurements

Abstract

 

The on-site measurement of the thermal properties of existing building envelopes is of utmost importance to fairly accurately calculate the thermal loss by transmission to the outside environment and so to define the building overall energy performance. This paper presents a preliminary investigation concerning the use of a new indirect method for measuring the thermal characteristics of building materials throughout the year based on the analysis of the material electrical properties. The main goal is to identify a relationship between thermal transmittance, moisture content and electrical impedance through relative electrical permittivity measurements.

Learning from Finland: from circular economy to circular building

Abstract

 

The principles of circular economy begin to be essential to favor sustainable processes and Finland is one of the few countries in the world that has developed a detailed plan for its application. Indeed the SITRA world map obviously affects construction industry at different levels and benefits are described through two operational addresses: the implementation of Housing First program by the Y-Foundation, that enhance a better usage of housing building heritage in order to solve a critical social issue, and the extensive use of wood elements for building construction, that introduces new ecological innovations into a consolidated technical tradition.

Effects of the digital transformation on the contemporary city project

Abstract

 

According to many sociologists and technologists today we live in the midst of the Fourth Industrial Revolution. The research aims to investigate this paradigm shift that is taking place in the contemporary city to understand how urban design is facing this digital transformation. Starting from the technological and digital innovations that are pervading the field of architecture, engineering and urban planning, this study will also try to understand how these radical changes will affect citizens’ life.

A cognitive approach for improving built environment and users’ safety in emergency conditions

Abstract

 

Cognitive Systems can be applied in architectural spaces to improve Built Environment performances basing on users’ needs. They can: 1) jointly monitor environmental conditions and human behaviours through Cognitive Built Environment (CBE) components; 2) use human-environment interaction models and related Key Performance Indicators to detect critical situations; 3) adapt CBE devices status to inform users on how to properly behave. This approach is applied to safety performances of outdoor (earthquake) and indoor (fire) scenarios, by proposing and testing solutions to support evacuees while reaching safe areas and rescuers’ support.

“Reconstructive re-drawings” and “reconstructive models” for history of construction. The experience of SIXXI research

Abstract

 

During the SIXXI research (“XX Century Structural Engineering: the Italian Contribution”, ERC Adv Grant, PI: Sergio Poretti, Tullia Iori) special study tools supported historical surveys on works. The experimentation on tools became an autonomous research topic, developing itself from the “reconstructive re-drawing”, pioneered by Poretti in the mid 1980s, up to 3D modelling and 3D printing. This paper resumes briefly its starting and illustrates most recent outcomes, as a board field of research in Construction and Structural engineering History.

Mapping and monitoring building decay patterns by photomodelling based 3D models

Abstract

 

A framework is presented for the evaluation and diagnosis of the state of conservation of the built heritage, based on the use of virtual immersive environments and three-dimensional models, as essential tools for the analysis and correlation of diagnostic data. Thus, some early studies are presented on the application of image processing routines that might extract from the point clouds some relevant information toward the semi-automated control of cracking patterns and surface alterations in heritage buildings

Rebuilt the space using stone or brick vaulted systems: catching the contemporary challenge of construction tradition

Abstract

 

In the recovery and restoration sites, as well as in the versatile word of university research about construction history, it’s not infrequent to study stereotomy for the re-proposal of stony or tiled vaulted systems, sometimes complex for their constitutive geometry, equipment, preliminary/subsidiary carpentry works. It represents a didactic study-key also in Engineering and Architecture Schools, through laboratories that teach to future designers a “know-how” that can be easily spent in their professional repercussions.

The refurbishment of of prefabricated residential buildings in socialist countries (1954-1970): methodological criteria and social perspectives

Abstract

 

Prefabrication was the instrument by which European countries, both the Eastern and the Western countries, sought to cope with the growing demand for housing after the Second World War. In the Soviet Union and the socialist countries, this choice is closely linked to the construction of the communist society.
The paper analyzes the housing and construction models developed in the Soviet Union in the late 1950s and subsequently exported to Eastern Bloc countries, focusing on the Albanian case study. The survey aims to define the main characteristics of the buildings with these systems, in terms of seismic resistance and energy performance.

The energetic characterization of solar-control environments

Abstract

 

Despite the increasingly pressing regulations in the energy sector (EPBD recast, law 90/2013 and the consequent decree 162 of 2015), which push towards policies and financial measures to promote buildings with almost zero energy, the quality of the internal environment remains one of the critical parameters on which to pay more attention in view of a consistent evaluation of the Nzeb building. The authors show, in the present paper, the results related to the energetic characterization of two test rooms, identical for surface and opaque envelope, but with different typologies of windows on the South-East and South-West wall.

Low-cost sensor network in cognitive buildings for maintenance optimisation

Abstract

 

Buildings cannot perform without a proper planning, execution and monitoring of Facility Management services. Moreover, occupancy monitor procedures for cognitive buildings are gaining momentum in performance optimization through dynamic adaption of indoor conditions (e.g. temperature, humidity, shadings). In this article, the application of a similar approach for automated execution of maintenance contracts (e.g. cleaning services) is presented. This approach is allowed by monitoring occupancy, through an ultrasonic sensor network. The methodology has been validated on a case study, concerning an office building in Milan, Italy.

An integrated system for façade additions combining safe, energy efficient and user- orientated solutions

Abstract

 

This research work, as part of the Horizon H2020 project, Pro-GET-onE (Horizon 2020 GA No. 723747), aims to demonstrate the attractiveness of a renovation strategy based on new façade additions that combine integrated technologies (GET) to achieve high standards in terms of socio-economic, energy and seismic performance. This document investigates, in particular, the possible transformation of the existing building envelope with external reinforcement structures, which generate energy-efficient buffer zones and at the same time increase the volume of the building.

Technological and performance issues in an intervention of retrofitting through greenery systems

Abstract

 

This research is aimed at evaluating the energy performance of an existing building in Mediterranean climate, and to assess the benefit coming from various retrofit solutions of the building envelope, such as green roof and facades. By means of dynamic simulations, validated with experimental results, the reduction in both internal air temperature and cooling load was estimated. In addition, the impact of the green shielding on the windows in terms of indoor visual comfort was assessed, and suitable soluitons were envisaged.

Fire safety issues in high-rise building façades

Abstract

 

Many recent fire events demonstrate that the need of improving the technical knowledge and the practical procedures in the design of the façade systems to be used in high-rise buildings, especially for what concerns the fire vulnerability, is still very strong. Through the analysis of some case studies and examples, the paper highlights the need to investigate and solve these aspects, both in terms of detail design and materials choice, as well as through appropriate specific FSE (Fire Safety Engineering) analysis and laboratory tests.

Building automation system to control natural ventilation in school buildings. The case study of “Michelangelo School” in Bari

Abstract

 

In school buildings high levels of Indoor Air Quality are required for the specific susceptibility to airborne pollution of occupants, but most of the data published in the scientific literature indicate that classroom ventilation in many schools is still inadequate. The low investment costs and the easy implementation of the Building Automation Systems allow a widely application in the existing buildings. This work studies the natural ventilation mechanisms based mainly on the stack effect of the central atrium and of the stairwells in order to design the building automation control systems.

The data were collected under different load and traffic speed magnitude. At this point of the research data are being analysed and compared, and the results reported on this paper.

People-centred deep renovation practices: from challenges to strategies

Abstract

This paper bases its considerations from the refusal of the prevailing perception that buildings consume energy, and assumes, on the contrary, that it is actually people, that consume energy for their comfort. This means that it is necessary to identify the end users’ behaviour, actions and habits in relation to the use of energy and their way to make decisions regarding energy retrofit interventions. This should be done considering also the economic savings and the costs, health and wellbeing of people as important drivers in the decision-making process. To do so, in this paper, we will try to position the main challenges encountered by users in the deep renovation first, hence disclosing some possible strategic actions for the uptake of a people- centred revolution of the renovation market in EU.

Construction principles of seismic and energy renovation systems for existing buildings

Abstract

Prefabricated “building systems” for the renovation of façades of existing buildings can achieve not only a physical building improvement of the envelope and thus result in lower energy consumption but also make an improvement in the resistance to seismic stress. To this end, the development of a combination of an exoskeleton and lightweight components as infill for the seismic truss system will be presented. Both a variability of the spatial appearance of the truss as well as the modularization of all construction components as a prerequisite for the prefabrication was examined and the system will be transferred into the real application by case studies as part of an H2020 research project.

Decision support tools for energy efficient and healthy school buildings

Abstract

 

Property owners are being forced to increase the energy efficiency of their buildings. Besides energy efficiency the indoor environmental quality (IEQ) of a larger part of Dutch primary school buildings is insufficient. This affects the performance, productivity and health of students and staff, and additionally has monetary consequences for school boards. The inability to achieve healthy, energy efficient buildings is largely explained by a lack of knowledge and experience in building renovation by school boards. The objective of the study is to provide school boards of primary schools with decision support tools to provide more insight in the technical, financial and organizational opportunities of renovation of school buildings. It is expected that this will lead to better balanced school buildings in terms of People (Indoor Environmental Quality), Planet (energy efficiency), and Profit (costs) and will contribute to a better work and learning environment for staff and students. Applied research methods are a literature review, semi-structured interviews, desk research, expert meetings, a focus group and design. Expert meetings were organized to get input for the design ofa decision flow chart. Both were tested by members of school boards. It was found that the tools provides more insight in the renovation decision-making process and opportunities to renovate the school buildings. By raising problem awareness about the indoor environment, the decision support tools are also expected to contribute to an improved IEQ in renovated school buildings. . The research was the basis for the development of a web tool for school boards: “Decision tree sustainable renovation primary and secondary school buildings”, published by Netherlands Enterprise Agency (RVO), design and consultancy firm Arcadis and the ‘Green Deal Scholen’.

Energy audit and performance optimization of a residential university building in heating dominated climates of Italian backcountry

Abstract

 

The paper proposes a novel holistic methodology to design the refurbishment of educational buildings in heating dominated climates of Mediterranean regions. The proposed approach is based on the solution of a constrained multi-objective problem by means of genetic algorithm implemented in EnergyPlus. The optimization process regards energy, and environmental objectives as well as the occupants’ thermal comfort. The case study of a student dormitory of Campobasso (Italian backcountry city) is proposed. The optimal set of energy efficiency measures shows approximately 55% of the energy saved during the heating season and 24% during cooling season.

Seismic strengthening through external exoskeleton

Abstract

 

The seismic hazard in Europe is one of the most critical issues of civil engineering. The necessity of improving existing buildings, in terms of energy and structure is always a new challenge for designers. The use of integrated improvement systems can be the solution to common obstacle from the project to the realization, such as the invasiveness, the cost and the duration of the construction phase. The current scenary is rich in different intervention techniques due to the heterogeneity of the buildings. The study focuses on two cases of seismic reinforcement through the use of steel exoskeletons in different contexts through different design solutions. Following the description of the issues related to the vulnerability of the two case studies, the procedures for evaluating the improvement are illustrated. Finally, the results deriving from the application of the strengthening structures are presented, showing ample margins for improvement in both cases up to the achievement of demand values.

Retrofit through Add-ons: the ABRACADABRA strategy as an opportunity for the energy renovation of private-owned and public buildings

Abstract

 

The EU environmental and energy policies are promoting energy efficiency retrofit actions, in spite of the fact that the renovation rate in the construction sector is very low. The ABRACADABRA project aims to activate a deep renovation market through volumetric additions (add-ons), including one of the most challenging sectors, the social housing. In order to demonstrate how the densification action could be an effective solution to promote energy efficiency interventions and new business models with the scope to shorten the payback time of renovation investments (both at building and urban scale), four different buildings in different urban contexts have been analysed. The simulation made on these case studies is divided in three steps: an architectural feasibility study, an energy saving analysis and a payback time calculation; in this last phase of the study the financial assumptions are fundamental. The real estate values like the sale and the rental rate, as well as the social values were well-thought-out and combined in order to find the best opportunity for profits and the shortest payback time. Moreover, additional issues were taken into account regarding the regulatory aspects and the technical feasibility barriers for this type of approach. Implementing this strategy means to add new units on the rooftop or on the side of an existing building, and this might face obstacles, such as urban regulation restrictions and the consensus among tenants or owners. To overcome these mainly social obstacles, the project promotes new policy recommendations that public authorities could adopt and approve and also counterbalanced measures to help tenants/owners accept and embrace the ABRA strategy.

Existing buildings retrofit through multi- objective optimization: a case-study

Abstract

 

In the light of the regulations on buildings energy performance, the designers face the need to choose among alternative design solutions, having to assess their effectiveness according to several -sometimes conflicting- points of view, such as the energy saving, the indoor comfort, the environmental and economic impact. This paper reports the results of the application of genetic algorithms to solve this “multi-objective optimization problem” in a building retrofit intervention in Italy. The results, even if related to a single case-study, suggest the optimal efficiency measures, whose robustness was tested in different Italian climatic zones.

Towards the cognitive building: information modeling for the energy audit

Abstract

The new paradigm of smart building requires the accomplishment of occupants needs through the analysis of data gathered within the building, which switches from activities host to provider of customized services for occupants. The digitalization supports this new approach, as the implementation of Building Management Systems (BMS) in Building Information Modelling (BIM) environment allows to link the information collected to a database. The contribution is focused on a case study of the University of Cagliari, the Mandolesi Pavilion, and it is aimed at implementing and improving energy audit procedures by the use of Building Information Modelling.

Experimental analysis of different multilayer insulated façade

Abstract

The presented work shows the results of the monitoring campaign conducted on two Cross Laminated Timber (CLT) test box equipped respectively with a micro ventilated facade and a thermal coat technology. Specifically, the experimental work was performed in order to compare the temperature levels of the Isotec® wall micro ventilated facade respect to traditional ETICS, with two different thermal mass, for facade insulation. The results showed that the micro ventilated façade, due to the shielding and air cavity comined effect contributes to reduce the summer heat stress with lower internal heat loads.

Proposal of a multicriteria decision-making approach for the choice between refurbishing or reconstructing an existing building

Abstract

 

The choice to refurbish or demolish/rebuild a building requires the analysis of numerous aspects. This paper highlights the role of the main factors involved and describes the methodological approach adopted, based on a multi-criteria analysis, for the definition of a decision support index. The final part presents the results of applying the methodology to a case-study of a school building, representative of a category of buildings with recurring typological and constructive characteristics.

An historical study on temporary and emergency post-disaster housing

Abstract

 

During recent years, the number of natural and non-natural disasters has drastically increased, due to the climate change, causing great damages on buildings and a high number of homeless people. However, post-disaster temporary housing solutions seem to have sustainability problems. Through a historical excursus, this work aims to analyse the steps that led to the current idea of temporary housing, in order to evaluate its functional and constructive characteristics. Finally, some considerations on improving thermal environment inside temporary housings are discussed.

Its scope is to support the complex balancing of conservation and functional requirements. The approach is based on an Agent-Based Modeling approach that includes entities belonging to the three macro areas – building, use process and users – considered.

Two Porcheddu’s quakeproof buildings in Messina reconstruction

Abstract

 

The Porcheddu Company of Turin (importer in North Italy of the Hennebique building system) was charged of 13 projects in Messi-na, after the 1908 quake: the study of the unpublished material in the Porcheddu archive, hosted at DISEG in the Turin Polytechnic sketches out two construction sites for quake-proof housings, the economical homes for the “Unione Messinese” in the Orto Botanico district, with a reinforced concrete frame and the Homes for the State Employees with pillars made of a prefabricated steel cage and on site poured concrete. The two different construction systems testify the business and law debate on quake-proof buildings.

An expeditious methodology for the seismic vulnerability assessment of building aggregates

Abstract

 

The objective of this research is the development of a protocol for the expeditous evaluation of seismic vulnerability of building aggregates in Italian historical centres, which is based on the determination of synthetic indicators to provide a preliminary assessment of their potential damage under the earthquake. The 2012 earthquake in Emilia-Romagna allowed to test the effectiveness of this method. Its application to the building aggregates of the historic center of Mirandola (MO) allowed to verify how it would have been possible to identify in advance the damage scenario recorded after the earthquakes.

For the construction an “expert” memory: the earthquake of 1818

Abstract

 

The paper highlights the progressive awareness acquired by local designers, looking for an expert memory of the earthquake. This is possible through a transversal reading of the architectural transformations and of the anti-seismic protections adopted in Eastern Sicily in pre-industrial times. The paper outlines a rapid overview of the interventions and reconstruction policies following the 18th century earthquakes. The research summarizes part of a detailed analysis of the archive documentation related to the repair and reconstruction interventions following the 1818’s earthquake in the territory of Catania (Italy). The final objective is thus to recover and analyse the design choices and the technical culture of the designers of the time.

Historic additional storeys in the cultural heritage of Palermo: critical analysis for the purpose of structural and energy improvement

Abstract

 

This paper analyses construction features and performances of additional storeys in historic buildings. The recurring characteristics of these historic accretions are investigated by focusing on the cultural heritage of Palermo, where the practice of extending buildings by raising new levels was widespread both in monumental and vernacular architecture, in public and private constructions. The performance deficiencies of additional storeys are examined in terms of structural safety, thermal comfort and building energy demand. On this basis, the utility of mapping these structures, their morphology and their location in the urban fabric is discussed.

Multi-hazard emergency management in historical centers: methods and tools for increasing mass-gathering safety in case of earthquake

Abstract

 

The use of historic city centers for touristic purposes, i.e. mass gatherings events (MEs), needs a multi-hazard approach which should jointly consider building heritage and hosted individuals’ emergency safety, by including effects of individuals’ behaviors to provide effective risk- reduction strategies (i.e.: interventions on critical Building Heritage; outdoor spaces layout reorganization; emergency management; wayfinding systems;). This work evidences the capabilities of such approach in case of MEs-earthquake emergency combinations, by taking advantaging of a validated evacuation simulator, through a case-study application.

Towards a safe school. Case studies on seismic improvement in existing school buildings

Abstract

 

The problem regarding seismic risk for school buildings has become increasingly important over the last years and national projects have been set underway to improve and adapt existing buildings to seismic risk. Many schools were built during historical periods when, even though foreseeing anti-seismic measures, were based on prerequisites different to those of today. It has become an urgent need to examine projects for a vast number of existing school buildings in relation to the important social role that they have always played.

High standard temporary buildings for housing emergency

Abstract

 

The project proposal consists of modular living systems made with dry technology, temporary, re-usable and energy efficient. The concepts of standardization and modular coordination are applied in order to minimize the production and execution times of the modules. The latter, taken together with the criteria of temporariness, reversibility, flexibility and energy efficiency become basic requirements for the project and allow the achievement of standards, levels of comfort and above all performances comparable to those of sustainable buildings of the latest generation.

“Unsual methods”. Italian notes on Military Structural Engineering in WWII (1943-1944)

Abstract

During the SIXXI research (20th Century Structural Engineering: the Italian Contribution), new historical archives were exploited: WWII and its aftermath apperead, evitently, as importants periods for the history of structural engineering. The war for Liberation of Italy (1943-1945) was a unique occasion to test and stress structural design applied to “emergency” scope. An impressive cross-fertilization between the American methods and “know-how” of the Italian technicians featured the “fisrt aid” operations of the Alleys [This papers is framed in the SIXXI project (www.sixxi.eu), thanks to a ERC Adv Grant funding (PI S Poretti, T Iori)]

Planning emergency in historical centres: from vulnerability to the definition of urban risk maps

Abstract

 

Historical centres are high-risk scenarios for evacuees during earthquake emergency. Herein, the preventive identification of criticalities concerning the emergency paths is important to preserve evacuees’ and rescuers’ safety and design effective risk mitigation solutions. This study proposes new indices for the quick evaluation of paths’ vulnerability and of possible debris amounts blocking the evacuation paths within the historical centre. Furthermore, starting from the obtained indices, the study produces probabilistic risk maps of the centre useful before and after emergency to plan the safe paths for evacuees and rescuers, design emergency operations and resource allocation.

An Optimized AHP-based methodology integrated in a Decision Support System for existing buildings safety

Abstract

 

The large-scale management and monitoring of buildings is a complex issue for the heritage buildings holders. Decision Support Systems (DSS) are increasingly applied and studied in the field of building from the scientific and technical communities. Multiple-Criteria Decision Analysis (MCDA), such as Analytic Hierarchy Processes (AHP), are widely used in building performance analysis. On the other hand, AHP are difficult to apply in building field because of the complexity of the problem. This work presents an optimized approach to use AHP integrated in the DSS and applied in the field of the safety and monitoring of R.C. buildings.

The recovery of the former University pediatric clinics in Cagliari: a project for the reuse, environmental redevelopment and structural and anti-seismic retrofitting of a modern building in a monumental centre

Abstract

 

This paper discusses some of the issues related to the redevelopment of the modern building, with a rethink about the spaces consequent to the need to change its planned use that is structurally more burdensome and the related anti-seismic retrofitting. The case study concerns the project for the restoration and reuse of the former pediatric clinics of the University of Cagliari, according to an integrated method of intervention which, in the absence of historical documents, made it possible to reconstruct the material and structural characterisation of the building and its technical and constructional features.

Measuring users-windows interactions in buildings: behavioural models for the summer season

Abstract

 

Including the human component in simulation software is of primary importance to enhance the building’s design and management. In particular, the user-window interaction impacts significantly energy and comfort profiles. Through an environmental and behavioural monitoring, this research investigated windows’ opening and closing actions during the summer season in three offices. The analyses highlighted that the behaviours are influenced by both environmental factors and time-related events. Using logistic regression techniques, stochastic behavioural models have been developed to predict windows status.

First elements of a research on the analysis of water leakage risk in discontinuous roofing: the calculation of vulnerability

Abstract

 

In recent decades the practice of operating after damage occurred has been replaced by planned and preventive maintenance also in building sector. In the field of built heritage management the culture of planned conservation has spread. Since water leakage from roof is one of the most common causes of damage to buildings, the study of roofing is essential. The paper presents the first elements of a research aimed at the definition of a numerical method for the analysis of the risk of water leakage from discontinuous roofing. After a general introduction to the concept of risk in this field, the general principles of the method are defined.

Structure and Language. The Enel building in Cagliari designed by Gigi Ghò

Abstract

 

The various topics of the Italian architectural debate of 1950s reveal themselves on the project of the Enel Palace of Cagliari, designed in 1957 by Gigi Ghò, Milanese engineer and architect. The reinforced concrete structure shows an interesting solution with base-hinged pillars in the shape of a “V”, and strongly influences the facades layout that, like GiòPonti, the architect considered not a design applied to a construction but an aspect of the very same structure [1]. The façade arrangement, the particular attention on the materials choice for finishes and the obsessive definition of the detail define Gigi Ghò personality.

Fire Safety Engineering: evacuation management in emergency conditions

Abstract

 

The disruptive events that occurred in Italy in 2016 have increased the attention to the evaluation of the evacuation procedures in emergency conditions. The strategies to adopt should be established on the basis of performance-based criteria of design and management, which are the same used in Fire Safety Engineering. In the specific case of the evacuation plan, the latter should be designed according to certain variables that may be successfully used also in other kinds of emergencies related to earthquakes or hydrogeological instability.

Textile mills in Friuli (XIX-XX century). Building technique analysis and seismic refurbishment

Abstract

 

The conservation of industrial architectures and the refurbishment project, must take into account the growing attention to the seismic risk of the built heritage, which the recent events of central Italy have made dramatically current. The different constructive nature and structural behavior of industrial buildings, impose a different approach, combining the new functional needs – and therefore the safety of the building – with its conservation as a testimony for future generations. The work focuses the Friulian textile industry buildings (XIX and XX century), studying their constructive techniques and identyfing some guidelines for the refurbishment.

Traditional bell towers: knowledge and safety in two compared areas

Abstract

 

The paper summarizes the main aspects of the in-progress PhD research that wants to provide supporting empirical-experimental analyses, deepening the aspects that can affect structural behaviour. The research will study emblematic cases in the Etna area, after having carried out a census and a typological classification never pursued previously. To validate the obtained results, the thesis will compare these buildings with the bell towers in the Valladolid area. The comparison will check whether similar buildings (located in different geographical areas) are characterized by a different durability from that on our national territory.

Windows use in school buildings: findings on the influence of occupants’ actions

Abstract

 

Occupants usually interact with windows to restore their thermal comfort but in spaces densely occupied, as in schools, windows also are fundamental to achieve good IAQ and avoid health hazards. Many researchers investigated the user-window interaction to identify recurring patterns but such surveys in schools are lacking. This paper investigates this relationship in an Italian classroom, monitoring occupancy, environmental parameters and adaptive actions. The proposed behavioural models are driven by indoor and outdoor temperature since they have been identified as the triggers parameters for opening and closing actions.

The developed system, result of a European founded project EASEE is a prefabricated composite panel that integrate both thermal insulation and exterior finishing.

Timbrel vaults in Sicily. Constructive techniques and intervention methodologies

Abstract

 

Almost totally ignored by the official historical and current technical culture, both locally and in the Italian ambit, thin brick vaults actually are mostly demolished or transformed in decorative ceilings. The detailed and comparative knowledge of many cases, encouraged also by building continuity in other countries, but also the partial and total reconstructions that have occurred in recent years, allow to properly assess potentialities and limitations, the real possibility or opportunity for their maintenance, rehabilitation or re-proposal, even preserving the structural function.

Types and models of ltalian Modern Heritage. The work of Giuseppe Vaccaro in Emilia Romagna Region (1930 – 1950)

Abstract

 

The aim of this contribution is the definition of a methodology to identify the formal and functional characters to be protected in restoration works on Modern architecture. This method can become the basis for further analysis on their performance improvement, and expecially on seismic vulnerability. The identification of their constructive and structural lacks in the relationship with the historic protective restricions and regulatory adaptation can be useful to plan seismic improvement intervention as required by current legislation. The study focuses on the work of Giuseppe Vaccaro in Emilia Romagna, particularly on four architectures built between the 1930s and the 1950s, having different destinations, both public and private.

Typological-GIS as a conceptual integration between GIS and BIM. First results on case study of Aversa

Abstract

 

This paper aims to explain the first results of a research on the application of T- GIS (Typological GIS) in the building regeneration design. T-GIS is conceived as an instrument allowing the user for a deep knowledge of built environment and so it could become an effective support in the complex building design process, also because it is potentially integrable with BIM. In fact, it might be the tool for conceptual integration between GIS and BIM. This article shows the first results of a complex and articulated work that is still in progress: the build of aT-GIS on the case study of a town called Aversa, North of Naples.

The acquisition phase is based on historical-archival analysis and visual inspections, to proceed with the subsequent planning and execution of diagnostic surveys. Successively, the handling of information collation and archiving follows criteria of Historic Building Information Modeling (HBIM), an innovative approach for coordinating refurbishment process, which, in the speciic study, contributes to the systematization of knowledge about materials, constructive techniques and residual performance levels about architectural components, limiting uncertainty of interpretation.

Innovative technical solutions for improving performance of wooden floors

Abstract

 

This paper presents an innovative technology of timber floor whose function is both the replacement of horizontal elements in historical buildings, not subject to constraints of protection, and the utilization in new buildings. The new system responds to the market demand that requires high performance characteristics in terms of stiffness in the plane, correct transmission of the horizontal actions, lightness and low thicknesses. The floor at issue is composed of two plywood panels glued in the intrados and extrados to a moulded grid panel in GFRP with a single warping of glass fibres. We want here to present the stages of study, research and design, that helped define an element considerably rigid and at the same time lightweight, trying to contain the thickness of the section. Laboratory testing phase has highlighted the increase in stiffness and flexural limitation that the coupling of the moulded grid panel with plywood panels undergoes in the different configurations.

The assessment of the reliability of an innovative 3rd generation solar cell integrated with “thermal belt” glass block

Abstract

 

Glass block is a building product widely used for the construction of translucent building façades and roofs. The need to adapt the product to the regulations in the field of energy saving and environmental sustainability has led to the design of innovative configurations, through the integration of different sub-components. These ones are able to improve its energy performance by means of the integration of a“thermal belt”, cold glued to the glass shells, which constitute the traditional glass block, and 3rd generation solar cells. This paper reports the first results of the experimental program designed to assess some durability components: inherent and critical reliability.

Lean construction applied to a BIM process: how to control point attribution in MEAT tender process

Abstract

 

Lean Construction (LC) and Building Information Modelling are the two methodologies linked by the same objectives. The former is an industrial optimization, which want to achieve the aim of performance increasing with the application to the AEC industry. These two concepts leaded Melzo school tender process writing. There are huge differences from a traditional process approach compared with BIM one, which leads project to a coherence high level. A deep LC principles understanding entail a distribution of the point to the different categories. The importance of LC criteria, in terms of points, imposes to the companies a change in the mind-set, from a lowest bid approach to a performance one. The study is based on the analysis of the responses to the case study procurement. Different competitors answer differently in function of Lean principles weight and their knowledge. The change in the state of mind leads the companies to offers value. In some cases, even if, many points were not able to change their behaviour. The behaviour modification will be a difficult transformation for the AEC sector.

Basalt fibre continuous stitchings for strengthening the dry stone masonry of the Lossetti Tower in Beura-Cardezza (Italy)

Abstract

 

Dry stone masonry is widely used in rural and mountain regions and its consolidation is a challenge issue if it is wanted to preserve the peculiarities of masonry texture. In this paper is presented the design approach used for consolidation intervention of Lossetti Tower – a medieval dry stone watchtower located in Beura-Cardezza (Italy, Piemonte Region) – using the technique of continuous basalt fibres stitching, consisting in creating a mesh of BF ropes, which pass through the masonry thickness and tie blocks together. A 3D laser scanner survey of the tower was executed and, to evaluate the technique effectiveness, diagonal compression test on masonry specimens was done, in order to develop a tailored design of the strengthening intervention, in perfect compatibility with the original structures.

At the beginning of the Thirties, Italy witnessed a widespread experimentation in new building methods resulting in the construction of examples of quite daring vaulted roofing using reinforced and partly prefabricated brick blocks, a predominantly national material. This research resulted in the construction of many buildings, initially to be used for industrial purposes, which offer interesting construction and structural solutions and are distinguished by their large-sized roofing, with single or double curved surfaces, a significant feature of internal spaces.

Entity and identity of metal additions in ancient buildings

Abstract

 

The research investigates the role of steel in pre-existence, at first confined to consolidation, later extended to reuse. The metal artificial nature and the untraditional constructive system make more complex the issue of addition visibility in pre-existence, employed for static purposes or functional aims. Anyway, the iron entity is expressed each time in a specific way, which is compatible to the historic building, concealed among the masses involved, or highlighted in its essentiality.

Analysis and control of façade claddings structural issues

Abstract

 

Although closely related with the building structure and required to possess adequate resistance to the acting loads too, the new cladding systems have shown not infrequently inconsistencies or mechanical deficiencies, such as to compromise their safety. The paper shows the necessity of studying and solving the structural aspects of façade claddings through proper numerical modelling and laboratory test, defining a systematic methodology for the evaluation of the structural aspects of the façade cladding that can be used both in case of new construction and building refurbishment.

Design of a construction site in a healthcare facility supported by simulative approaches

Abstract

 

This research aims at providing a model to support the design of a low-impact construction site, in a healthcare facility, through an integrated system of BIM models, as databases of geometric information and semantics relating to use, and qualitative simulations of energetic- environmental phenomena and behaviour and activities of the actors involved, developed through a Game Engine. The interaction between the “enriched” model and the simulation environment represents a possible way of estimation of the risks, costs and impact on the healthcare setting, supporting the selection of the best management and design solutions.

The role of semantic enrichment in Building Information Modelling

Abstract

 

In current application of Building Information Modelling to building design processes, two main limits have emerged: 1) restricted representation spectrum and 2) inefficiency in supporting collaboration because of the low-level semantics shared among the actors. The objective of this paper is to provide a conceptual framework about these two relevant aspects of collaboration in BIM methodology, as well as to demonstrate the necessity of moving from modelling approaches based on information to innovative representation systems based on knowledge.

Decision-making methods applied to regenerative process of existing buildings

Abstract

The path traced in construction sector leads to an increased attention to building heritage and its refurbishment into “nearly zero-energy buildings”. The regeneration process of an existing building is complex and requires the designer to use the distinctive features of the building and of the site where is built in order to achieve the objectives. One of the most important moments of this process is the choice of the interventions. The objective of this research is to identify a replicable decision-making method to support the designer in identifying the optimum solution through the Operations Research.

Industrialized building and the quality of housing in Turin during the years of the great immigration

Abstract

 

The industrialization of construction practices became established much later in Italy than in other European countries. The impetus of the so-called “Italian economic miracle” in the subsequent fifties, together with the still unresolved problem of reconstruction, induced designers and building contractors to resort to the use of prefabrication. The present work has the aim of investigating this complex situation, connected to the affirmation of building industrialization in the planning of public cities in the period from just after the II World War until the beginning of the eighties, taking the case of Turin into consideration as a study case.

Contribution to the knowledge of wide span wooden roofing in Bologna area

Abstract

 

This paper deals with the analysis of some examples of large wooden trusses in important churches of Bologna carried out through a survey campaign conducted with a laser scanner.

All results highlighted the knowledge that the structural design of these wooden roofing is strictly related to their dimensions and assembly, the understanding of which is functional on any restoration intervention.

KREO: Kinetic Responsive Envelop by Origami

Abstract

 

One of the most interesting fields of contemporary research is addressed to the realization of kinetic building components. It can be obtained by using foldable surfaces, that are light surfaces which increase their strength thanks to the folds. They could be useful to form envelopes, coverings, shading elements or entire pavilions. KREO is classifiable in this field; it is an experimentation concerning geometric modelling and fold texture, in relation with kinematism. In addition, in KREO project, tests of composite materials are carried out with CNR of Catania, to evaluate the most useful of them, to this purpose.
