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 ...
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 gezielte Informationen zu unterstützen. Der vorliegende Beitrag beleuchtet anhand der vorhandenen Literatur eine Vielzahl ...
Um Kosten, Energieimporte und CO2-Emissionen zu reduzieren, ist im Energiekonzept der Bundesregierung vorgesehen, den Wärmebedarf für Gebäude bis 2020 um 20 Prozent und den Primärenergiebedarf bis 2050 um 80 Prozent zu senken. Dazu soll der Anteil der jährlich energetisch sanierten Gebäude von 0,8 Prozent auf zwei Prozent erhöht werden. Bei zwei Prozent energetischen Sanierungen pro Jahr wird jedes ...
