“…Panao et al [59] discussed the energy required by a nearly zero energy building in a Mediterranean climate (Lisbon). The thermal insulation thickness from 40 to 60 mm and double glazing of 6/16/6 mm are found to be the cost-optimal solutions for most real houses studied.…”

“…Some of them pointed out the need to define this concept more precisely. In the research field, there are case studies of new constructed nZEB dwellings [17], or the renovation of a single family house to achieve the nZEB level in the Mediterranean region [18,19]. Lindkvist et al [20] presented an extension of the nZEB concept to the near Zero-Energy Neighbourhood; the authors concluded that, although this constitutes an area with opportunities for intervention, the knowledge of nZEB renovations is not being transferred and financial and social barriers should be addressed.…”

EU regulations are gradually moving towards policies that reduce energy consumption and its environmental impact. To reach this goal, improving energy efficiency in residential buildings is a key action line. The European Parliament adopted the Near Zero-Energy Building (nZEB) as the energy efficiency paradigm through Directive 2010/31/EU, but a common technical and legislative framework for energy renovations is yet to be established. In this paper, the nZEB definition by COHERENO was adopted to evaluate several energy renovation packages in a given building, which is also representative of the Spanish building stock. Global costs are calculated for all of them following EPBD prescriptions. Two economic scenarios are analysed: with entirely private funding and with the current public financial incentives, respectively. The results show the divergence between optimum solutions in terms of costs and of minimum CO 2 footprint and maximum energy saving. Moreover, in the absence of enough incentives, some inefficient renovations could achieve a global cost close to the optimal cost. The optimum solution both in terms of energy performance and global costs was carried out and described.

“…Another statistics-based concept is that of 'archetype', defined as a theoretical model that represents each of the different building typologies [50]. This method is used to classify the building stock according to different parameters such as climatic conditions, construction period and context.…”

“…As for the moment the Spanish regulation presents a lower level of exigency, in terms of energy efficiency in building renovation [18], than the last European directive [17] and also compared to the limits of PE and Given this information and following the recommendations of some publications [10,50], the use of the German Passivhaus label [79] as a reference to define nZEB requirement is here considered as a reasonable approach [80]. The target values taken into account are presented in Table 8.…”

“…As seen in section 2, the analysis of the building stock can be realised through different approaches, namely reference buildings (corresponding to real building examples) [44], building typologies (corresponding to common buildings) [48], and archetypes (defined as a theoretical model representing different building typologies) [50]. We propose to use the archetypes approach that allows us to scale-up the results from the building to the territorial scale.…”

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.
