Transforming old residential properties into smart buildings with the help of a cloud-based toolkit that can be used in the planning and construction phase as well as for evaluating and monitoring energy performance. HEART expects to reduce the conversion and restoration times by about 40%, which converts into about 70 working days. Smart buildings save energy by using the latest insulation materials, and they also send energy back into the system, according to a modular logic. Based upon an energy performance approach that applies to the entire building, the toolkit is designed to achieve very high energy efficiency in existing residential buildings, especially in central and southern Europe where climate change and energy transition have increased the peaks in energy usage both in summer and in winter. The toolkit can also be used for new residential and commercial buildings.

HEART – Holistic Energy and Architectural Retrofit Toolkit – is funded by the European Union through Horizon 2020.
