What we do
Services
Electrical installation
The basis for everything else: supply lines, distribution, lighting and connecting the plant equipment. In new builds as much as in existing buildings, for single units as much as for entire properties.
Work behind the grid connection fuse. We handle the registration with the grid operator, because GDS is a registered installation company with Stromnetz Berlin.
Air conditioning
Design, installation and maintenance of split and multi-split units as well as VRF systems. For offices, medical practices and commercial space as much as for flats in existing buildings. Work on refrigerant circuits requires certified competence under the EU F-gas regulation.
Heat pumps
Air-to-water and brine-to-water systems, from replacing the heating in a single property to converting an entire holding. Requires electrical registration with the grid operator, and from 4.2 kW counts as a controllable load under Section 14a of the German Energy Industry Act.

Pitched and flat roof installations with or without storage, including registration with the grid operator and in the German market data register. For property managers a tenant electricity model is an option as well.

Solar thermal
Collector systems for hot water and heating support. Often the more economical addition where roof area is limited and hot water demand is high.
Smart home and KNX
KNX-based building automation: lighting, shading, heating and climate on one bus instead of isolated solutions. Vendor independent, and therefore still extendable years later.
