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...

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...

The German government is committed to reducing the primary energy demand of buildings by 80% by 2050. This requires increasing the rate of thermal retrofits from the current 0.8% to 2.0% per year. To explore how new and existing policies and programs could deliver the increased retrofit rate,...

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...

Installations covered by the European Emission Trading Scheme (EU ETS) can use credits from the Clean Development Mechanism (CDM) to cover a share of their emissions. The CDM credits are generated by low-carbon projects in developing countries that require the CDM support to become financially...

Die Bundesregierung hat beschlossen, den Primärenergiebedarf von Gebäuden bis 2050 um 80 % zu senken. Dazu muss die energetische Sanierungsrate von derzeit 0,8 % auf 2,0 % pro Jahr gesteigert werden. Um festzustellen, wie durch neue und bestehende Politikinstrumente diese Steigerung der...

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...

Der Gebäudesektor ist ein Schlüsselsektor des Energiekonzepts der Bundesregierung, unter anderem da sich in diesem Sektor ein Großteil der CO2 Emissionen mit Gewinn einsparen lässt (Levine et al. 2007). Bisher führt allerdings nur ein geringer Teil der Wohngebäudebesitzer umfassende...
