The IBA DOCK is the floating exhibition and office building of the International Building Exhibition, Hamburg. The energy
concept and energy technology were provided by IMMOSOLAR. The IMMOSOLAR Energy Management System (EMS)
made it possible to implement a zero heating energy concept: solar thermal collectors on the roof of the IBA DOCK help a
brine/water heat pump to heat the building. The heat pump takes the environmental heat it requires from the River Elbe
via heat exchangers in the pontoon or directly from the solar thermal system. The heat pump’s remaining electricity
requirement is covered by a photovoltaic system on the roof of the IBA DOCK. This trend-setting energy technology can
be viewed as part of the building exhibition. Further information.

An eco-resort made up of 5 single holiday homes and one hotel in the nature reserve of Peneda-Gerês in the north of Portugal. A solar system with 6m2 of collector surface and 450 litres of reservoir capacity in each holiday home guarantees a large percentage of the electricity supply.
The energy supply for the hotel and its‘ wellness area is supported by a solar system with 36 collectors and 3000 litres of reservoir capacity.

Supply by solar energy and Installation of a hot water system for the Restaurant with up to 400 guests per day.

• 20 solar collectors IS-Pro 2H, in total 40 m²
• 2000 Liter Water tank
• Deltasol M
• ACS (service water heating)

Climate control of the new workshop of the Auto manufacturer Audi by solar thermal energy.

Fitness Center with expanded Wellness-area and interior pool.

120 m2 solar collectors cover the total energy demand in combination with Gas boilers. Multiple-staged, dynamic loading and unloading by means of most modern technology. A Data logger, coupled with a GSM Modem facilitates a remote controlled fine tuning and monitoring of the system and provides its highly-efficient loading factor.
