Sustainable Solutions for Affordable Retrofit of Domestic Buildings

SUREFIT Project demonstrates fast-track renovation of existing domestic buildings by integrating innovative, cost-effective, and environmentally conscious prefabricated technologies. This is to reach target of near zero energy consumption through reducing heat losses through the building envelope, and energy consumption by heating, cooling, ventilation, and lighting, while increasing the share of renewable energy in buildings.

This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 894511. The performance of novel renovation technologies in SUREFIT Project were studied by building level simulations. In the simulations, the technologies were classified into three renovation packages, including a passive package; consisting of bio-aerogel thermal insulation, PV vacuum window, and phase change material (PCM).

A ventilation package; comprising insulating breathable membrane and window heat recovery (WHR) and a generation package, including photovoltaic/thermal (PV/T) system, solar assisted heat pump (SAHP) and a new application of daylight technology. These technologies have been installed at a demonstration phase in 5 representative buildings in different European climates.
