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.

The Billing Building, a Kunsthalle Mannheim building dating from 1907, was completely renovated. The various measures are intended to reduce energy costs by 25%.

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.

MoniSoft can be used with a Java environment on any operating system, both via the command line and via a graphical user interface (GUI).

MoniSoft for building monitoring and energy-based optimisation

MoniSoft, a Java-based and platform-independent software package, simplifies the monitoring and operational analysis of buildings. Stringent measurement data processing with quality assurance functionality and diverse options for context-based data visualization optimizes energy managed buildings.

Integrally designed
Energy innovations in energy-plus child day care centre

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.

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 storage
New office and laboratory building uses waste heat and geothermal heat

With its new “Energy Centre”, the Brandenburg University of Technology Cottbus-Senftenberg now has an energy-efficient new building where six departments have been able to conduct research under one roof since the middle of 2013.

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...

Climate-neutral campus
The climate-neutral campus relies on renewable energies and seasonal heat storage

The “Climate-neutral campus Leuphana University Lüneburg” project is developing a sustainable energy concept for the university itself and the adjacent urban district of Bockelsberg. The aim is to supply all the electricity and heat using renewable energies...
