Recent global peer-review reports have concluded on importance of buildings in tacking the energy security and climate change challenges. To integrate the buildings energy efficiency into the policy agenda, significant research efforts have been recently done. More specifically, the public...

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,...

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...

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...

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...
