AS Solar Headquarter

In Hannover, the future of energy-saving in large buildings has started. At the 31st of May 2011, the wholesale distributor for solar technology and pellet systems, AS Solar, introduced its new headquarter. This building produces more energy than it actually consumes. For the first time, an industrial sector has been redeveloped with the latest accomplishments of the energy technology. The result is a worldwide unique, plus-energy-building which is used as office, production facility and warehouse.

This success is the result of the energetic renovation of the building shell to passive house standard, the implementation of a heating system, which is adjusted to the load conditions, the integration of a ventilation system with highly efficient heat recovery and the installation of photovoltaic and solar thermal plants. And also the CO2 balance is outstanding. The building shows the energetic saving potentials for a building, which is equipped with a coordinated selection and reasonable combination of passive measures and active, technical components.

Like a phoenix from the ashes, an industrial ruin at the Nenndorfer Chaussee has developed into a solar model project.

The building had been used for the production of televisions from Telefunken up to the beginning of the eighties. Afterwards, it had been the headquarter of an industrial-scale print shop, had partly been used by freight forwarders until 2000 and was then vacant. Vandalism caused many damages.


AS Solar does not consider new buildings, but energy saving and resource conservation through professional renovation of old buildings, as biggest challenge for economic and energy policy. “Here we have, with an investment of 7,5 Mio. Euro, created a worldwide individual and unique plus-energy-building, that can be used as office, production facility and warehouse and which is, with a total size of 12.500 square meters, one of the biggest projects of its kind as well as an energetic lead project”, explains the managing director of AS Solar, Gerd Pommerien.

The thermal heat and air-conditioning is entirely done by solar energy and biomass. The produced solar energy significantly exceeds the own demand and hence will be feed into the grid. Thereby, up to 80 households can benefit. Furthermore, the company plans a solar filling station with 76 parking spots directly in front of its headquarter.

Because of the model character of the project, AS Solar was funded with 100.000 Euro by the European Fund for regional Development (EFRD). On the ground floor of the building, two seminar rooms, one supply kitchen, a bistro and in the northern part, a “technology showroom” have been established. On the mezzanine floor, office rooms as well as toilets, showers and social rooms were integrated.
