IEA HPP Annex 30: Retrofit Heat Pumps for Buildings

Energy utilisation in the built environment is one of the most important aspects that must be addressed if energy targets are to be met. In Europe, around 40 % of primary energy use is due to the building sector. Heat pumps are among the most environmentally friendly and efficient heating technologies available. Retrofitting is a means of rectifying poor existing building performance by improving the standards and thermal insulation of buildings and/or the replacement of old space conditioning systems by more efficient systems. The focus of HPP Annex 30 has been retrofitting in all kinds of domestic buildings. This article gives an overview of the work.
