Solon AG – Production and administration building Adlershof

For his new head office in Berlin-Adlershof the solar technology specialist Solon puts particular emphasis on a minimum energy consumption and the application of regenerative energy sources. Prof. Dr. M. Norbert Fisch, director of the Institut für Gebäude- und Solartechnik (IGS) at the TU Braunschweig and head of the EGSplan GmbH, Stuttgart, developped therefore a novel energy and climate concept. VIP/QASA sandwich elements from VARIOTEC are of a big importance due to their multiple functions.

Data evaluation and monitoring in the VARIOTEC research house since Jan. 2006 through the Fraunhofer Institute for solar energy systems ISE:

1. Comfort passive house
   with individual controllable room air temperature concept, CO₂controlled
2. Complete building envelope of Vacuum Insulation Panels
   this means a living space gain of min. 10 %
3. Allergy compliant conception
   Selected raw materials for interior work, (bamboo, glass, aluminium, spruce, upstream air, respect. pollen filter)
4. Regulated ventilation system with exhaust air heat recovery (degree of efficiency 82 - 86 %)
5. Barrier free living area respect. interior work conception
   Variable multigenerational house
6. Closed water circulation
   Membrane small sewage works for WC, garden, etc.
7. Residual heat coverage by solar heating balance storage in the summer semester in warm water cisterns
8. Phase-change material (PCM)
   for latent heat storage, switching temperature 23 – 27 °C
9. Passive room cooling
   by the KKS system with a rainwater cooling cistern, temporary discharge of the PCM > 27 °C
10. Comfort climate
    no radiation asymmetry, no draft, regulated and filtered fresh air, optimal room air humidity(40 – 50 % rel. air humidity), no convection with dry heating air, no condensate, as no thermal bridges and consequently no mildew
