The study proposes a comparison between the thermal performances of a real building, built according to the German standard DIN 4108-2:2003, and a refurbished one (in a theoretical investigation), aimed at satisfying the more restrictive requirements of the new version (i.e., 2013) of the same standard. The analysed building, completed during the 2012, is located in Berlin. The building has good performances in terms of energy demand for heating. Diversely, during the first years of operations, some overheating problems have been verified in summer. Because of sustainability motivations, cooling devices are not installed. An energy-oriented retrofit is here proposed, aimed at verifying if the fulfillment of the new version of the DIN 4108-2:2013 will produce better microclimatic conditions in summer. The results show the necessity of an accurate approach to the topic of summer thermal protection.

Abstract

The study proposes a comparison between the thermal performances of a real building, built according to the German standard DIN 4108-2:2003, and a refurbished one (in a theoretical investigation), aimed at satisfying the more restrictive requirements of the new version (i.e., 2013) of the same standard. The analysed building, completed during the 2012, is located in Berlin. The building has good performances in terms of energy demand for heating. Diversely, during the first years of operations, some overheating problems have been verified in summer. Because of sustainability motivations, cooling devices are not installed. An energy-oriented retrofit is here proposed, aimed at verifying if the fulfillment of the new version of the DIN 4108-2:2013 will produce better microclimatic conditions in summer. The results show the necessity of an accurate approach to the topic of summer thermal protection.
