Refurbishment with low-exergy concept
Building refurbishment with exterior wall heating

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.

Building refurbishment
Derelict factory building transformed into energy-plus building

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.

Data centre as a heat source
Office building as a laboratory for sustainable construction

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.

Utilising daylight
General refurbishment of the Kunsthalle Mannheim

Museums are mostly monumental public buildings with architecturally ornate facades that are also very durable. They are often listed as historic monuments, which presents considerable hurdles for those carrying out refurbishment.

Building automation
Cost-effective decentralised fieldbus system tested

SmallCAN can be used to considerably simplify the automated operation of buildings. In terms of its basic structure, the simple and flexibly extendable fieldbus system has its origins in the automotive sector and requires very little power itself.

Sustainable construction
Passive house primary school with timber construction

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.

Solar thermal energy
Decentralised supply to local and district heating networks based on solar thermal energy

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...

Energy-optimised sports hall
Sports hall built using passive house construction methods with sophisticated energy concept

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...
