The building sector plays a major role when it comes to meeting climate targets. An analysis by DIW Berlin based on data from energy provider ista SE shows that in the past two years both the temperature-adjusted heat consumption in German multi-apartment buildings and the temperature-adjusted...

Der Gebäudesektor spielt eine wesentliche Rolle bei der Erreichung der deutschen Klimaschutzziele. Die Auswertung des DIW Berlin basierend auf Daten des Energiedienstleisters ista zeigt, dass in den vergangenen beiden Jahren sowohl der Heizenergiebedarf in deutschen Mehrfamilienhäusern als...

Improving the energy efficiency of residential buildings is of paramount importance to reduce CO2 emissions and hence to achieve a climate-neutral building stock - the objective of the German government for 2045. Thereby, a focus on the existing building stock is needed, as regulations for new...

Um die Klimaziele bis 2030 zu erreichen, muss der Gebäudesektor deutlich weniger Kohlendioxid (CO2) ausstoßen. Die Analyse des DIW Berlin auf Basis der Daten vom Immobiliendienstleister ista zeigt, dass der Heizenergiebedarf sowie die temperaturbereinigten CO2-Emissionen im Jahr 2022 im...

In this paper, we identify key drivers and barriers for the adoption of building energy retrofits in Germany, which is promoted by public policy as an important measure to address the future challenges of climate change and energy security. We analyze data from a 2009 survey of more than 400...

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...

Residential buildings strongly contribute to global CO2 emissions due to the high energy demand for electricity and heating, particularly in industrialised countries. Within the EU, decentralised heat generation is of particular relevance for future climate policy, as its emissions are not...

The political discussion on energy efficiency is focusing more and more on the building sector due to its susceptibility to potential market failures like the negative external pollution effects of CO2 emission. Using a discrete choice approach, this paper aims at deriving factors which increase...

This paper re-conceptualizes the planning process in the big data era based on the improvements that non-linear modeling approaches provide over the mainstream linear approaches. First, it demonstrates challenges of conventional linear methodologies in modeling complexities of residential energy...

A transformation of prevailing energy systems requires adequate measurement systems. In this paper we propose an energy-service based indicator set and a composite index for monitoring sustainable energy development in the residential sector and electricity and heat supply in Austria. The system...
