Building renovation in the EU : scenarios and impact assessment.
The work presented in this report aims to provide scientific support to building renovation policies in the EU by promoting a holistic point of view on the topic. As part of the pilot project 'Integrated techniques for the seismic strengthening and energy efficiency of existing buildings', renovation scenarios are defined, and their impact is investigated considering seismic retrofit, and energy efficiency upgrading of residential buildings, both independently and in an integrated way. An integrated analysis framework, proposed earlier to identify priority regions across the EU, is extended here to investigate the impact of renovation scenarios. Within this framework, retrofit is modelled through a target seismic and/or energy performance of buildings, which is quantified by an upgrade of their structural and energy attributes. A series of impact metrics are introduced to investigate first the renovation potential of regions (i.e. the capacity of individual building classes within a region to yield benefit), and subsequently the impact of renovation scenarios (benefit in absolute terms) across the EU-27 with a focus on priority regions. Impact metrics include benefit-to-cost ratios along with the reduction in economic loss, loss of life, and space heating energy consumption. Impact metrics are further assessed considering a variability in renovation cost and planning period. Three strategies are followed for the definition of renovation scenarios: (i) renovating predefined macro-taxonomy classes, (ii) renovating predefined fractions of the building stock, and (iii) renovating building classes so that renovation is beneficial in economic terms. Overall, the efficiency of a renovation strategy increases along with its selectiveness, i.e. the capability of targeting buildings of specific structural and energy attributes rather than generic classes. Inevitably, this comes at the cost of increased complexity in scenario implementation. The results presented in this report clearly illustrate that integrated renovation is capable of tackling the multidimensional problem of building renovation, providing a risk-proofed, sustainable, and inclusive building environment. The economic benefit due to integrated renovation was found to be in the order of magnitude of the highest economic benefit among the seismic and the energy renovation ones (or even higher), whereas integrated renovation presents the unique capability of reducing fatalities and energy consumption at the same time, and depending on the scenario, to a greater extent.
