Renovation wave: Energy and environmental analysis of heat pumps and renewable energy systems for buildings

The "Renovation Wave" is a European Union (EU) initiative aimed at addressing the environmental, economic, and social challenges posed by the building sector. The initiative focuses on renovating existing buildings to make them more energy-efficient, sustainable, and climate-friendly. It is part of the EU’s broader efforts to achieve its climate and energy goals, including the European Green Deal, which aims for net-zero greenhouse gas emissions by 2050. Life Cycle Analysis (LCA) is a key tool in helping the Renovation Wave achieve its ambitious goals by identifying sustainable, low-carbon materials and technologies. Optimizing energy use and carbon reduction across the building's life cycle is also a target supported by LCA. Part of the methodology introduced is to cluster energy systems combination based on electrification with heat pump implementation and renewables. Finally, and part of the new directive of buildings, the cost-effective decision-making approach is part of the methodology. By integrating LCA into renovation projects, Europe can ensure that its building stock is not only energy-efficient and sustainable but also cost-effective and resilient in the face of climate challenges.
