Putting energy efficiency first is important, as energy savings are the easiest way of saving money for consumers and to reduce greenhouse gas emissions.
Which measures are needed to save energy, by decreasing the energy need (e.g. the building envelope) and the energy use (the technical building systems), can be calculated with the help of the EPB standards.
As a second step, the remaining energy use can be covered by renewable energy sources, like photovoltaic (PV) panels on the building or building site.
The calculation of the contribution of PV is included in the EPB standards. Particular attention is paid to the possible policy choices on how a surplus of PV that is produced on site and exported to the grid is appreciated in the energy performance of the building.
This is explained in the Short video – The EPB Standards Explained – Exported energy, Option A in detail.
