Conducting a building thermal efficiency retrofit (or further thermal retrofit) is a long and relatively complex decision-making process involving building owners, managers, residents/tenants, and construction industry professionals. A variety of information instruments exists to support...

Eine energetische Gebäudesanierung (Sanierung zur Erhöhung der Energieeffizienz) erfordert einen langen, relativ komplexen Entscheidungsprozess für Gebäudeeigentümer, -verwalter, Mieter sowie Bauhandwerker. Es gibt verschiedene Möglichkeiten diese Akteure in Ihren Entscheidungen durch...

The German government has committed to reducing the primary energy demand of buildings by 80% by 2050. Achieving this reduction will require foremost efficiency improvements, with a first milestone of a 20% reduction in heat demand levels by 2020. Given that about 80% of today’s building stock...

Zwischen 2002 und 2007 verabschiedete die Bundesregierung die Nationale Nachhaltigkeitsstrategie und das Integrierte Energie- und Klimaprogramm. Beide Programme enthalten klare energie- und klimapolitische Zielsetzungen: So sollen die Treibhausgasemissionen bis zum Jahr 2020 um 40% gesenkt...

Between 2002 and 2007, Germany introduced its National Strategy for Sustainable Development and its Integrated Climate Protection Program, which both defined clear energy and climate-related objectives, setting an emissions reduction trajectory of 40% below the 1990 level by 2020. This spurred...

Executive Summary The German government aims to reduce primary energy demand by 80% until 2050 and heating demand by 20% until 2020. Besides the need for additional efforts to achieve these targets, Germany has already implemented a set of policies and programmes to increase investments in...

The building sector is a key focus area of the Energy Concept of the German Federal Government, among other reasons because it has the potential to avoid a large share of CO2 emissions while also saving costs. Thus far, however, only a small percentage of residential building owners have...

The German government has committed to reducing the primary energy demand of buildings by 80% by 2050 and to attaining a thermal retrofit rate of 2%. Achieving both goals will require deep thermal retrofits across the existing building stock. To meet this challenge, the government is exploring...

Die deutsche Bundesregierung hat das Ziel gesetzt, den Primärenergiebedarf im Gebäudesektor um 80% bis zum Jahr 2050 zu senken und eine energetische Sanierungsrate von 2% zu erreichen. Umfassende, tiefe Sanierungen im Gebäudebestand sind notwendig um beide Ziele zu erreichen. Daher untersucht...
