Summary

The aim of the study was to show the need for performance documentation, monitoring, and data integration during the lifetime of an energy system. An improved estimation approach of heat pump performance was introduced. This approach was developed by integrating manufacturer and building energy management system data. Direct and indirect measurements were combined using the data fusion method. This heat pump estimation approach was tested on substation where two heat pumps were integrated to support building energy supply system. Two approaches for exhaust air heat recovery: 1) within air handling unit; and 2) within the entire building using heat pumps, were assessed. The results showed that use of only direct measurements could result in fail conclusion regarding energy savings. The results showed that exhaust air heat recovery within the entire building using heat pump was favourable solution when district heating price was above 60% of electricity price.
