Experiences from the first German EPBD implementations: - Field tests for residential and non-residential buildings - Certificates for well-known national and international buildings

摘要

In preparation of the implementation of the Energy Performance of Buildings Directive (EPBD) the responsible German Ministry' has undertaken several actions including the development of a new energy performance calculation procedure for non-residential buildings (DIN V 18599) and two field tests for the certification of residential and non-residential buildings. This paper presents the main results of the evaluation of the field tests concerning the form and acceptance of the certificate, the necessary expertise of the issuers, the duration of the work, possible simplifications, etc. The second half of the paper deals with experiences made at Fraunhofer Institute of Building Physics with issuing of national and international energy performance certificates for well-known buildings such as the Berlaymont building (Brussels), several German ministry buildings (Berlin), a high-performance office building in China (Shanghai) and two European schools (Brussels).
