Energy Performance Certificates
Starting from 2009, you can ask for an Energy Performance Certificate when buying or renting a house. Such a certificate gives you an idea of how energy-efficient your house or apartment actually is. Taking into account things like insulation, heating, design of the building and ventilation, the certificate gives you a precise idea of how high your future energy bill will be when you actually live in your new dwelling. Energy performance certificates are valid for ten years, unless renovations are made before the date of expiration, which would make an earlier revision useful. The certificate is handed over to each new owner and a copy of it is provided in case you let.
You want to do something about the energy efficiency of your house? But where to start? Solar panels are very popular, but are maybe not the most efficient first step in your personal energy investment program.
First of all, you need to get the picture of the current status: an energy audit would be a good start. Optimizing your insulation and in door ventilation would be wise areas to investigate first.
