a novel rapid survey form for the vulnerability assessment of Existing Building Stock based on the index Building approach
Systems Man and Cybernetics, 2019Co-Authors: Giuseppina Uva, Valentino Sangiorgio, Pier Luigi Ciampoli, Valeria Leggieri, Sergio RuggieriAbstract:The seismic vulnerability at regional scale of the Existing Building Stock deserves a particular attention from the scientific community, considering that it is a crucial phase for the estimate of the possible losses (damage, human lives, disruption) due to hazardous events. For developing a comprehensive and effective approach, different skills are required, ranging from the expertise in structural analysis to the knowledge of informatics systems aimed at data collection. Within this framework, the use of survey forms able to provide a preliminary vulnerability index based on observational data (properly calibrated on mechanical or empirical analyses) represents one of the most adopted methodologies for large-scale vulnerability analysis. The aim of this paper is the proposal of a novel survey form for the vulnerability assessment of the residential Building Stock, based on the results obtained from a mechanical approach applied to “Index Buildings”, linked with an informatic platform through a Decision Support System. After the compilation, this new survey form is able to associate any generic sampled Building to a pre-defined “Index Building” and thence to associate a structural capacity.

integrated assessment of energy performance and seismic vulnerability of Existing Building Stock at urban scale through bim an application to fiera del levante
Systems Man and Cybernetics, 2019Co-Authors: Giuseppina Uva, F Iannone, Valeria LeggieriAbstract:The paper presents a research work concerned with the integrate assessment of seismic vulnerability and energy performance of Existing Buildings at urban scale through BIM (Building Information Modelling).At the urban scale, it is often required to manage large set of Buildings, for which it is not possible to perform detailed investigation, modeling and analysis. At this scale of analysis, an additional issue is the coexistence of different Building components and performance requirements (structural safety, functional and aesthetic efficiency, energy efficiency, and so on), which often have a dynamic interaction.For this reason, the modeling approach should be able to encounter this complexity and provide the interaction of multiple expertise, in order to provide optimal solutions of the critical issues and vulnerability of Buildings.Within this context, the research has proposed and tested a framework structured through a suitable BIM model finalized to implementation of integrated simplified evaluation procedure of seismic vulnerability and energy performance at urban scale.The objective is to provide an innovative tool for the performance-based assessment in a context of uncertainty and incomplete information typical of the urban scale analysis.The proposed approach allows to manage information from different source and quick investigations concerns structural safety and energy efficiency, and it has been focused on the case study of “Fiera del Levante”, a trade fair district extending over 280.000 m2, composed by several Buildings aged from 1929 to 2012, that host about thirty events (including international fair shows) throughout the year as well as conferences and/or exhibitions.

assessing the energy saving potential of an Existing high rise office Building Stock
Energy and Buildings, 2018Co-Authors: Tatiana Alves, Luiz Machado, Roberta Vieira Goncalves De Souza, Pieter De WildeAbstract:Abstract In underdeveloped countries, the lack of Building energy consumption data makes it hard to decide upon interventions in the Existing Building Stock. In order to overcome this difficulty this study develops a comprehensive framework to identify and analyse the energy saving potential of an Existing Building Stock category. The methodology consists of six basic steps: a process for defining reference Buildings, dynamic archetype model simulations, an energy consumption baseline estimation, energy retrofit measures selection and a cost optimal pathway analysis, development of energy saving scenarios and estimation of Building Stock energy savings potential. In order to apply the proposed methodology, a case study of the high-rise office Building Stock took place in the city of Belo Horizonte, Brazil. The energy consumption projection results for the next 20 years show that there are significant opportunities for energy efficiency improvements. Cost effective energy savings of up to 24% would be possible in the high-rise office Building Stock. Overall, energy saving scenario projections emphasize the urgency of dealing with the Existing high-rise office Building Stock but also highlight that to reduce the energy consumption of the current Building Stock the policy makers should pay close attention to the new Buildings.

a methodology for estimating office Building energy use baselines by means of land use legislation and reference Buildings
Energy and Buildings, 2017Co-Authors: Tatiana Alves, Luiz Machado, Roberta Vieira Goncalves De Souza, Pieter De WildeAbstract:Abstract Understanding the energy demand of cities is a challenge especially in countries such as Brazil where the lack of Building energy consumption benchmarks makes it hard to decide upon interventions in the Building Stock, as neither the Existing nor the attainable energy performance are known. Aiming to overcome these difficulties this study develops a framework to estimate the Energy Use Intensity (EUI) baseline of an Existing Building Stock category based on the investigation of land use regulations, a land tax database and field surveys. These offer a starting point to estimate current energy consumption and promising interventions without having to study specific Buildings in depth. A case study of the high-rise commercial Building Stock took place in the city of Belo Horizonte, Brazil. Three representative typologies were identified. For each of these, archetype energy models were created in order to assess EUI. The analysis of the EUI baselines highlights differences between archetypes, explaining the impact of technical choices on the overall electricity consumption and indicating a growing tendency of energy consumption for forthcoming Buildings. The archetype analysis also provides knowledge to identify the most promising energy savings potential and thus to support further energy policies in the city.

energy efficient retrofit and life cycle assessment of an apartment Building
Energy Procedia, 2015Co-Authors: Jana Kmeťkova, Michal KrajcikAbstract:Abstract While new Buildings should be designed as intelligent low or zero-energy Buildings, refurbishment of the Existing Building Stock may present even a greater challenge, when in particular financing of the necessary investments to energy saving measures poses the biggest barrier. As the residential sector in the EU is responsible for about 40% of the total energy consumption and up to 40% of the total carbon dioxide emissions, the residential Building Stock offers high potential for energy savings. By applying the life cycle assessment, it is possible to optimise the social, economic and environmental aspects, starting from the extraction of raw materials, up to the final disposal of waste materials.A case study of a selected representative residential Building located in Slovakia is presented, for which the cost-optimal levels of energy performance are determined in terms of life-cycle costs of the Building. Three variants of renovation were defined, each variant having different level of thermal insulation of Building constructions. The method of Life-Cycle Costs was used to evaluate the economic feasibility of the suggested renovation scenarios for the apartment house.

the energy improvement of the urban Existing Building Stock a proposal for action arising from best practice examples
2015Co-Authors: Teresa Parejo NavajasAbstract:Improving energy efficiency in Existing Buildings represents a great opportunity for reducing greenhouse gas emissions. Numerous measures to increase efficiency and decrease emissions have been put in place in cities all around Europe and in the US. But there are some that stand out from the rest, like New York City, which is a remarkable example of commitment to the fight against climate change. This is due to the city’s special characteristics, with a great urban density and a large percentage of greenhouse gas emissions coming from its aged Building Stock, which has urged its authorities to take important measures in order to eliminate (or at least diminish) its adverse effects. However, there is always room for improvement. Thus, a comparative study between some of the most successful measures developed in selected European cities and New York City, will be aimed at giving some useful elements to legal professionals in order to improve the Existing energy efficiency measures for greening the Existing Building Stock in any city around the world.
