Thermischer Komfort im Sommer - Ergebnisse aus dem Energiemonitoring eines mit Passivhauskomponenten sanierten Bürogebäudes

Thermal comfort in summer - results from the energy monitoring of an office building refurbished with Passive House components.

In 2011 the Institute for Housing and Environment moved to a new domicile in Darmstadt, the so called IWU-house. Beforehand, the administration building built in 1962 was modernised to almost Passive House standard (average heat transfer coefficient Ū (opaque) = 0.11 W/(m²K) and Ū (transparent) = 0.85 W/(m²K)). Special attention was paid to summer heat protection, and an appropriate concept for office use was developed.

The measurement results show that not only the energy consumption and CO₂ emissions of the office building were greatly reduced; even without air conditioning the refurbishment with Passive House components also ensures an excellent indoor climate in summer.
