A municipal housing company in the south of Sweden constructed three energy efficient multi-family apartment buildings in 2020 in which smart technologies were implemented. One of the buildings with a total heated area of 976 m2 is designed to have a primary energy number of 19.3 kWh/ m2 /year compared to the 85 kWh/m2/year as required by the Swedish Building Regulations. Apart from building envelope energy efficiency measures solar panels were installed and the excess electricity produced is stored to a battery. The excess heat from the solar panels is used in the bedrock heating system with cooling possibilities. The aim of this energy solution is to make the buildings partially off-grid. The actual electricity produced from the solar hybrid panels is so far lower than the simulated self-consumption and the battery is not used to its full potential. The rainwater collected was enough to save 75 percent of drinking water volume normally used for toilet flushing according to calculations made from incomplete data. A faulty installed meter, a fire incident, the use of several different systems and companies for collecting and logging data, and many other contributing factors affecting the possibility to evaluate the installed smart energy systems needs to be remediated. A recommendation is to assign someone the role of energy coordinator with the purpose of making evaluation possible within one year.
