The H2020 EXCESS project aims to develop Plus Energy Buildings (PEBs) across different European climatic zones. The article "Plus Energy Buildings: From concept to reality" published on Innovation News Network explores the potential of PEBs to transform local energy supply chains and serve as a blueprint for future sustainable buildings, providing insights into the demo projects implemented in different cities.

Demos in Graz (Austria), Helsinki (Finland), Valladolid (Spain), and Hasselt (Belgium) will cover all four climatic zones of Europe and will allow different approaches according to the characteristic of each zone.

• In Hasselt, Belgium, a social housing complex supplies surplus energy to neighbouring buildings through various sustainable energy generation systems.
• In Valladolid, Spain, a historical palace is being upgraded to a PEB by optimising conventional technologies and installing air heat pump systems, PV and PVT panels, lithium-ion batteries, and electric vehicle charging stations.
• The Helsinki demo building, located in a smart district, utilises a hybrid geothermal energy system and integrates photovoltaic and PVT panels for electricity and heat production.
• In Austria, the Graz demo case involves the renovation of a former feed production silo using multifunctional façade elements and a geothermal heat pump.
