“…Therefore, by combining these aspects, a Portuguese RB was defined based on the most representative construction solutions, geometries and construction materials of the residential buildings built in the city of Lisbon between 1961 and 1990. Other reference buildings may be defined within the Portuguese building stock to reflect distinct construction periods or locations, by taking into account the typification of the Portuguese constructions presented in Brandão de Vasconcelos et al [27]. Nonetheless, the RB adopted is nationally representative in terms of construction solutions and its configuration is representative of Lisbon's building typologies, in the 1960-1990 construction period.…”

“…In order to create RBs, Brandão de Vasconcelos et al [27] proposes three different approaches. The approach choice for the present study is the RBv data/exp methodology, referred to as the most suitable approach for the Portuguese context, as it combines the existing Portuguese databases and the expertise knowledge.…”

“…Methodologies to define reference buildings are provided, for instance, by Brandão de Vasconcelos et al [15] and Filogamo et al [16]. In this regard, a harmonized building typology concept was established by the IEE-TABULA Project (Typology Approach for Building Stock Energy Assessment) with the aim to assess the energy performance of the European residential building stocks and determine the effectiveness of the energy conservation measures and the potential energy savings [17].…”

Abstract:The refurbishment of the existing building stocks represents a great potential for energy savings. To make the refurbishment effective, proper modeling of the current energy performance is needed. In most European countries, few and low quality data on the energy performance and on the refurbishment of building stocks are revealed, which increases the risk of not getting representative results. The article presents a new methodology for an effective bottom-up energy modeling, aimed at evaluating the current energy performance of housing stocks. The model is set up according to the IEE-EPISCOPE Project (Energy Performance Indicator Tracking Schemes for the Continuous Optimisation of Refurbishment Processes in European Housing Stocks, 2013-2016), which developed a framework of reliable data and clearly stated model assumptions, as to overcome the lack of data while guaranteeing transparency. The model, applied to an Italian region, is based on statistical data and uses the building typology approach. The energy performance is calculated by means of a quasi-steady state method. A correlation between the estimated and the real energy consumption is obtained. The model allows disaggregating the residential building stock in subsets to identify the main potential for energy savings in specific contexts. Improvements of the current data availability are strongly advisable to keep the model updated.

“…In terms of scale, we observe that a majority of applications of the methodology have been at the building or component scale, especially to compare different constructive solutions and construction materials or to optimize the insulation thicknesses of the building envelope [8,12,32,33,[37][38][39][40][41][42]. When at the building scale, studies typically consider only one specific typology for a given period of time or year (e.g.…”

As tomorrow's cities are already largely built, many strategies stress the importance of urban renewal processes to address current energy issues. This paper focuses on the Spanish residential building stock built until 2001, which has a low level of energy performance.Considering the current economic crisis, the future lies in renovating the built environment, which holds a significant energy-saving potential. This potential is here quantified by applying the cost-optimal methodology, initially proposed by the Energy Performance of Buildings Directive, and which calculates costoptimal levels of minimum energy performance requirements at the building and component scale.The originality of our study lies in the application of this methodology at the territorial scale, comparing different retrofitting scenarios by scaling-up building-scale results through an archetypal approach. We also describe an Excel-based tool allowing two types of studies: (i) at the building scale, for one archetype in a particular climatic zone; (ii) at the territorial scale, to have an overview of all building archetypes and climatic zones simultaneously. Results include economic aspects, energy consumption and savings and associated emissions.The outcome can help construction-sector firms adapt their business plan, while also providing stakeholders with decision-support to promote a sustainable renewal of the building stock.
