The energy-plus “Ludmilla-Wohnpark Landshut” housing estate was built on an industrial brownfield site. Close monitoring and the subsequent optimisation of the building operation significantly reduced the energy consumption.

The multifunctional use of district heating networks could already provide an important step towards achieving low-emission heating supplies in the medium term. In a research project, AGFW, Solites and the Technical University of Dresden have investigated the technical impacts caused by...

The two-storey St. Franziskus primary school in Halle is almost entirely timber-built and meets the passive house standard. With the energy-optimised building concept, the school authorities wanted to ensure a high level of learning comfort with manageable operating costs.

It was intended that the new two-field sports hall in Dresden-Weixdorf should cause the lowest possible operating costs. In spite of the large building volume, it was planned to have a heating demand less than 20 kWh/m² p.a. and a primary energy requirement that was about 50 % lower than...

A successful heat transition can make a significant contribution to the success of the energy transition. Using the example of the Hamburg district of Wilhelmsburg, a rapidly growing urban neighbourhood, this is now being demonstrated with the real laboratory of the energy transition IW³.

A company from the solar power industry has refurbished a derelict factory building – and with such thoroughness that it has now been transformed into a multifunctional energy-plus building. The developer is now using the building in Hanover as an office building with production and storage areas.

The “Noah’s Ark” is a children’s day care centre that has an exemplary design not just in architectural and building ecology terms but also in regards to the structural technology and energy use. Two groundwater heat pumps are matched with a thermal solar power system.

Central heating normally requires a central circulation pump. The fact that this does not have to be the case has been shown by a pump manufacturer with extremely small and very quiet pumps. The high-efficiency pumps require on average just one watt of energy and can supply radiators individually...

For this fundamentally new heating concept, a minimally invasive refurbishment system is combined with the low-exergy heating principle. Here, a surface heating system is applied to the outside of the facade during the refurbishment of the building.

The “Z3” office building for the Ed. Züblin AG company utilises innovative concepts for the building structure and building services technology. The compact building almost entirely produces its own energy, for example using solar power and by utilising waste heat.

In Freiberg, the performance of two single-family homes conceived as energy self-sufficient buildings is being scientifically investigated. The buildings’ very low heating requirements are met by generously sized solar collectors and heat storage tanks, supplemented in each home...

In autumn 2011, a hotel chain opened in central Munich its first hotel conceived as a green building in accordance with the sustainability principles of the EU programme of the same name. The post-war building, which has undergone extensive refurbishment, has been designed...
