Short project's description:
Konnex Projekt- and Planungsbüro GmbH together with IMMOSOLAR GmbH created one of the most energy efficient residential buildings in Hamburg. This apartment building is an example of state of the art Green Building in property development. This project set itself the aim of creating accommodation that offers a future-proof concept with the highest levels of comfort for its occupants. This building is distinguished by its extremely low energy costs, high degree of independence from external influences and its careful handling of natural resources. This ambitious goal was achieved through energy efficient architecture and the consistent use of environmental energy. IMMOSOLAR energy technology made it possible. A combination of solar thermal collectors and a brine/water heat pump safeguards DHW heating and central heating via a comfortable underfloor heating system. The heat pump draws its energy from the collectors and deeply sunk geothermal probes. The probes are regenerated with superfluous solar heat, a process controlled by the EnergyManagementSystem. The building draws around 85 % of its heat demand from the environment. Further information: Reference sheet

Short projects description:
The building created by the "Sonne 16" housing project is a passive house that runs exclusively on solar energy. This means that the building envelope and the building services are high grade to the extent that insolation covers almost the entire heat demand directly via the walls and large south-facing window, as well as indirectly via the DHW heating system. This pioneering energy concept from IMMOSOLAR is based on combining heat source, solar thermal collectors and a brine/water heat pump with 17 kW output. The DHW demand is largely covered by a solar thermal system with 32 m² collector area. Washing machines too are supplied with solar energy via a DHW connection, which reduces costs even more. This is precisely the point of this future-proof apartment building: the energy concept based on the optimum utilisation of solar energy keeps operating costs low in the long term. And then there is the question of the comfort and convenience of the residents of the "Sonne 16"  passive house. Combining the particularly high grade thermal insulation, ventilation and underfloor heating makes for a very pleasant atmosphere inside this apartment building. Further information: Reference Sheet

Short project's description:
Energy concept, design and site management for energy system for full climate control using renewable energies, preparation of DHW in single family dwelling of 440 m² of habitable space located on the island of Mallorca. The installation consists of 20 m² of solar collectors, a 22 kW geothermal pump, 400 ml of geothermal drilling situated in the garden of the dwelling and distributed in 4 wells of 100 ml. The solar collectors save 32% of the requirements of the dwelling, the remainder is produced by the geothermal heat pump with a COP of 4.1 – 5.5. Heating is provided via low-temperature heated floors to optimise the solar contribution and boost the yield of the heat pump. Refrigeration is provided by fan coils under suspended ceilings designed to work with a geothermal heat pump. Further information: Reference-sheet; News

Short project's description:
The energy concept and energy technology are from IMMOSOLAR. The energy management system provides heating, cooling and DHW for the luxury villa. Solar thermal collectors on the roof help brine/water heat pumps to heat the building using area heating systems, as well as providing DHW heating. The reversible refrigerant circuit of the heat pumps provides cold water for air conditioning the building using fan coils. Geothermal probes act as a heat source for the heat pumps and as a heat sink for cooling and excess solar thermal energy. Sizing was carried out using the calculation model developed by IMMOSOLAR for solar geothermal systems. Further information: Reference-sheet; News

Short project's description:
The building services for this house were modernised according to the brief, which was to achieve the best possible energy efficiency and savings. An EnergyController regulates the storage of available solar energy in the different system areas with great efficiency, giving DHW heating priority. Excess solar energy is used to heat the indoor swimming pool. This enables substantial energy savings in this area. The system was designed with potential future expansion in mind.
