The energy transition will require considerable increases in energy efficiency, particularly in residential buildings. Financial support mechanisms, information and adviceprograms and dedicated training and certification of craftsmen are already in place to stimulate energy efficiency investment. Nevertheless, the required annual rate of thermal building refurbishment of around two percent is so far ...
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 undertaken comprehensive thermal retrofits, and the target retrofit rate of 2% remains a distant goal. In order ...
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, this paper examines the thermal efficiency retrofit decision-making process among owners of single- and two-family ...
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 will remain in place beyond 2050,thermal retrofit of this existing building stock is essential (Figure 1). ...
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 year, so it is achievable even if the government only targets buildings that are already planning a renovation. ...
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 what role tax support options could play in encouraging thermal retrofits and ensuring that they deliver the ...
The Eurozone is still stuck in a downward spiral: high public and private debts weigh on potential growth; gloomy prospects for growth prevent the further reduction of these debts. A European plan to support growth should be a complement, and not a substitute, to the ongoing efforts to reduce public deficits. It should both encourage structural reforms and incentivize investments. In the short term, ...
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 participants at each stage of this process. This paper highlights the existing literature on information instruments ...
