“…Due to the low replacement rate of existing buildings -about 1-3% per year in EU countries [6] -the majority of buildings that will exist in 2050 is already built, with many of them having a low level of energy performance [7]. In this context, the retrofit of existing buildings offers significant opportunities for reducing energy consumption and GHG emissions [8]. In fact, the International Energy Agency (IEA) estimates that the potential energy savings for 2050 are of about 1,509 million tonnes of oil equivalent [9], with a 50-75% saving when considering only the improvement of the building envelope [10].…”

“…Initially, this methodology was proposed by the EU to study different building retrofitting scenarios. It consists in a multi-criteria assessment that allows comparing different levels of intervention under various macro-economic scenarios, in terms of cost-effective strategies and energy and environmental savings [8,12,17,22,[30][31][32][33].…”

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.

“…Because the method described in this paper is proposed as a direct application of the European comparative approach, the following previous experiences were considered particularly relevant: Kurnitski et al (2011), Hamdy et al (2013, Ganic and Zerrin Yılmaz (2014), Pikas et al (2014), Ferrara et al (2014), Brandão de Vasconcelos et al (2016), Becchio et al (2016), Ashrafiana et al (2016), Ortiz et al (2016a, b).…”

“…With this aim also, Ferrara et al (2014) applied a simulation-based optimization process, combining the use of TRNSYS (Solar Energy Laboratory 2012) with GenOpt (Wetter 2008). Brandão de Vasconcelos et al (2016), who considers only the envelope technologies, adopted a two-step approach which consists in (i) preliminarily discarding of measures with the same or worse thermal transmission coefficient and higher global costs comparatively with other measures and (ii) combination of all resulting measures with each other, creating 35,000 packages of measures. A good number of building variants (i.e., 2000) was considered also by Ortiz (Ortiz et al 2016a, b), who conversely applied a Bbrute-force^approach to obtain a complete characterization of the problem.…”

Identification of cost-optimal and NZEB refurbishment levels for representative climates and building typologies across Europe

et al. 2017

The energy consumptions of the building stock are playing a central role in the energy policy of the European Union. While the Member States are applying the Directives in force, the European Commission is working to update the regulatory framework. Specifically, it is necessary to achieve the great unrealized potential for energy savings in existing buildings. With this aim, the nearly zero-energy building (NZEB) target was introduced, and a comparative methodology framework to calculate cost-optimal levels of minimum energy performance requirements was proposed. This study focuses on the issue of building renovation, and it presents the results obtained with the application of a cost-optimal calculation method for identifying proper retrofit measures to reach costoptimal levels and NZEB levels. The assessment takes into account an exhaustive set of passive and active renovation options and it was extended to various building types of 60s-70s (residential and non-residential) in a wide range of representative European climatic conditions. A very relevant energy-saving potential was found for all cost-optimal benchmarks, and in many cases, the obtained NZEB refurbishments have resulted interesting also from an economic point of view.
