Individual metering and charging in existing buildings
Government bill 2013/14:174 stated that it should not be the individual building contractor or owner who assesses whether it is cost-effective to install individual meters; instead Boverket should make a general assessment. Boverket was therefore commissioned to examine whether individual metering and charging is a cost-effective investment, and to specify in which cases metering systems for heating, cooling and domestic hot water should be installed in buildings.
Article 9 of the Energy Efficiency Directive (2012/27/EU) requires member states to ensure that building contractors and property owners install individual meters so that each apartment's energy use for heating, cooling and domestic hot water can be measured. The aim of measuring each apartment individually is to increase households' awareness of their energy use and give them the possibility of lowering their heating costs.
Sweden has implemented the article through the Act on energy measurement in buildings (Lagen om energimätning i byggnader, 2014:267). This act includes requirements on building contractors and owners to make it possible to measure heating, cooling and domestic hot water individually in each apartment. However, the requirement only applies if the measure is cost-effective.
Boverket completed the first part of this government commission in 2014, about individual metering and charging in new construction and reconstruction projects. The present report is Boverket's response to the commission's second part, about individual metering and charging in existing buildings.
