Heat pumps in buildings with low energy demand – comparisons with a current test standard

How does a traditional heat pump system operate in a house with a low heating demand? In what way does a smart grid connection affect the heat pump? Will the operational parameters differ from those that heat pumps of today are optimized for? And how? These questions are relevant as nearly zero energy buildings (nZEBs) soon will be standard for new-built throughout Europe due to the Energy performance of buildings directive. The results from this recent research indicate that the standard for testing of heat pumps should be revised.
