Gebäudeenergieausweis in der Schweiz - Methodik des GEAK®

Energy Performance Certificate in Switzerland — Methodology of GEAK®.

More then one year the energy performance certificate of Switzerland GEAK® is well-established. In the beginning of August 2009 the GEAK® started as a public online tool. The certificate is a combination of energy performance based on calculated values and consumption data. The calculated energy demand could be validated with consumption data. The core of the certificate is an energy rating with two classifications. The classification of the efficiency building envelope describes the thermal quality of the envelope and the classification of the overall energy performance of the building describes the energy efficiency of the whole building incl. building services, lighting and appliances. The certificate contains the energy rating, the description of the building in the current state and advices for efficient improvements. In the future, proposals of cost optimized reconstructions possibilities could be done with an additionally GEAK® Plus tool.
