In the 2010 Energy Concept, the German government committed to reducing the primary energy requirement of buildings by 80% by 2050 and to increase the thermal retrofit rate from 0.8% to 2% per year. The 2% target is less than the 3%1 rate at which outer walls are currently being renovated each...

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 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...

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...
