Abstract

ABRACADABRA is an European Project funded by the Horizon 2020 Program, based on the assumption that substantial increase in the real estate value of the existing buildings can play a key role in the deep renovation. The project aims at demonstrating to the key stakeholders and financial investors the attractiveness of a new renovation strategy based on volumetric Abstract Add-ons and Renewable energy sources (AdoRES) intended as one (or a set of) Assistant Building unit(s) – like aside or façade additions, rooftop extensions or even an entire new building construction – that “adopt” the existing buildings (the Assisted District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the Buildings) to achieve nearly zero energy. The creation of these AdoRES aims at reducing the initial investment allocated for the greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat deep renovation of the existing building creating an up-grading synergy between old and new. The ABRA strategy can thus result sales. Due to the changed climate conditions and building renovation policies, heat demand in the future could decrease, in the implementation of a punctual densification policy that aims at fostering the investments in deep renovation of the existing prolonging the investment return period. built environment, driving process innovation in the construction and the real estate sector. The main scope of this paper is to assess the feasibility of using the heat demand – outdoor temperature function for heat demand The paper, after outlining the main aspect of the project, focuses on a case study in Italian context, where different technological forecast. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district is consisted of 665 solutions and related economic impact are analysed: from a deep renovation to AdoRES strategies and different scenarios of buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and three district renovation. The preliminary feasibility study and cost assessment, show the benefit given by the presented strategy in renovation scenarios were developed (shallow, intermediate, deep). To estimate the error, obtained heat demand values were overcoming actual financial e technical barriers.
