Energy-Efficient Buildings

In Germany, the greatest potential to save energy is offered by existing buildings: These use around three times more energy for heating than new buildings. In addition, around 83% of the total energy consumed in a private household is required for space heating and hot water. Up to 80% of this can be saved with a professional refurbishment and modern building services. The fact is, however, that only around a third of the energy savings potential is exploited on average in a refurbishment project.

dena initiates showcase pilot projects.

Everyone involved profits from energy-efficient construction and refurbishment: tenant and landlord, the skilled trades, the environment and the economy. In close cooperation with politicians, scientific institutions, industry, associations and market protagonists, dena therefore develops nationwide information and motivation campaigns and showcase pilot projects which have a long-term influence on the investment decisions made by private and public property developers and home owners. Our message is: Energie sparen. Wert gewinnen, which translated means Save energy. Gain value.

Main projects

Efficient Homes Page  This project has ended.

Old buildings which have been refurbished in an energy-efficient fashion require a lot less energy than comparable new buildings. dena’s project "Efficient Homes" proves in more than 375 buildings that energy-efficient methods of construction can reduce the energy requirements of a building by up to 87percent on average.

Energy-Efficient Building in China  Page

China is seeing continuous growth in energy demand, including in the building sector. dena is assisting investors and decision makers in the planning and construction of climate-friendly, energy-saving buildings to promote climate protection and energy efficiency.

Energy-efficient local authorities Page

A local authority that uses less energy will save money and do its bit to tackle climate change at the same time. dena has therefore launched a project to encourage the German local authorities to introduce systematic energy and climate change management. The project offers selected authorities assistance and support in their journey to better energy efficiency.

Energy Performance Certificate for Buildings  Page

As energy prices rise, energy-efficient buildings are becoming ever more attractive. The Energy Performance Certificate documents a building's energy quality and provides specific modernisation hints for saving energy. As a tool which enhances market transparency, the Energy Performance Certificate is stimulating investment in refurbishment.
