Abstract

Europe’s energy efficiency challenge in buildings mainly concerns the energy efficient refurbishment and investments in the existing building stock. Yet, today, only 1,2% of Europe’s existing buildings are renovated every year. The actual investment gap in the deep renovation sector is because high investments are required up-front and they are generally characterized by an excessively high degree of the risk, by long payback times and by the “invisibility of the energy benefit”. It is, therefore, necessary to develop concerted and innovative actions. The EU project ABRACADABRA (“Assistant Buildings’ addition to Retrofit, Adopt, Cure And Develop the Actual Buildings up to zero energy, Activating a market for deep renovation”) aims at demonstrating to the key stakeholders and financial investors the appeal of a new renovation strategy based on volumetric Add-ons and Renewables (AdoRe) intended as one or as a combination of Assistant Building unit(s) that “adopt” the existing buildings to achieve nearly zero energy. The conception of new AdoRes aims at reducing the initial investment allocated for the deep renovation of the existing building creating an up-grading synergy between old and new. The ABRA strategy aims at implementing a precise densification policy to foster the investments in the deep renovation of the existing built environment. In this context, the project aims at fostering a legislative and market change accelerating the revolution towards nearly Zero Energy in the existing buildings and in the urban settings of the EU cities. The paper focuses on case studies in different geographical and climatic contexts, where different solutions are analyzed: from standard renovation up to the AdoRe strategy. All solutions are compared in terms of energy saving, non-energy benefits, and cost-effective analysis.
