Clean heat at what cost? Economic optimization of residential space heating in Massachusetts
Electrifying space heating is a key strategy to reduce greenhouse gas emissions from buildings. The Commonwealth of Massachusetts has adopted a statutory target of net-zero emissions by the year 2050, and the state has predicted that 100,000 homes must be converted each year to electric space …

Passive Houses in Sweden. From Design to Evaluation of Four Demonstration Projects.
… than before. The total measured energy use for space heating, domestic hot water and common electricity was in Värnamo 36 kWh/m2a, in Frillesås 50.5 kWh/m2a, in Alingsås 65.7 kWh/m2a and in Lidköping 51 kWh/m2a, revised to a normal year. The peak load for space heating is measured to be somewhat …
