| Energy Performance Certificate Germany has implemented the EU guideline with the Energy Savings Act (EnEV 2007), which came into force on the 1st of October 2007. From the 1st of July 2008, the energy performance certificate will become stepwise compulsory when renting, selling and leasing properties. On or after the 1st of July 2008, the Energy Savings Act requires that an energy performance certificate must be made available when selling, renting or leasing a residential building built in 1965 or earlier. The energy performance certificate is compulsory for newer residential buildings from the 1st of January 2009 and for non-residential buildings from the 1st of July 2009. This will also require that an energy performance certificate is publicly displayed in all public buildings in Germany with more than 1,000 square metres of usable area. Since 2002, the energy performance certificate has been compulsory for new buildings and buildings that have been refurbished in a comprehensive way. | ![]() |
| Minergie MINERGIE® is a Swiss quality label for new buildings and modernized old buildings of all building categories. This particular key size is suited best, since the building quality can be evaluated over the energy consumption. The power requirement per square meter of heated floor space serves as a measure for this evaluation. Products which have a positive effect on this evaluation measure, are certified according to the associated module and carry the appropriate label. | ![]() |

The Same Result Using 50 Percent Less EnergyEnergy efficiency is not a topic of the future. Instead, it is a task of the present. Rising energy costs, the “Energy Performance Certificate“ (Energy Passport), and the Minergie standard compel a new way of thinking. In the past, energy saving was always associated with a loss of comfort. Today, things are different. Waldmann shows ways to lower energy expenses, while maintaining - or even increasing the level of lighting comfort.
