Für die exklusive Villa in Ekali mit Freibad haben wir eine hocheffiziente Niedertemperaturheizung vorgesehen. Die Marmor-Fußboden wurden mit einer sanften Fußbodenheizung ausgestattet. In Räumen, wo große Glasflächen vorgesehen sind wurden zusätzlich Konvektoren, optisch versteckt, installiert. Bei sehr kalten Tagen sollte vermieden werden, dass ich diese Räume die Fußbodentemperatur stark ansteigt.

Die Zentrale wurde so ausgestattet, dass jederzeit die Umstellung auf moderne Heizsysteme (Wärmepumpe für Heizung und Kühlung, Erdwärme) möglich ist. Geplant ist auch die Beheizung des Freibades mit gleichzeitiger Kühlung für das Gebäudes um den CO2-Ausstoß weiter zu reduzieren.

Special Educational Support Centre in Dingolfing

The modern school building construction requires an interdisciplinary knowledge in all areas of civil engineering, as well as a broad knowledge of both classical and modern technologies. The systems shall be designed so that a long-term use can be expected without changes and additions. The rapid development of electrical installation, lighting technology and in particular the communication technologies and the BUS technology are opening up broad paths for optimization of the building and maximizing energy savings.

One can embed today many functions of other disciplines in bus technology and so will not only cut costs, but made the central control of the systems is possible. On the planner very high demands are made, it must optimally advise the client and he must recite the solutions the use and value of the Optimize the building and last but not least are economically feasible.

Lower bavarian archeology museum

The construction of the multi-purpose hall of glass was used as the center of energy from the sun energy. By interposing a heat recovery between exhaust air and fresh air as well as the use of a heat pump was aimed to optimize the energy conservation . In a museum , visitors are frequencies and the times when visitors come very irregular.

This problem was solved by the use of motion detectors and air quality sensors . The exhaust air from the museum rooms reached via the staircase ( without channels ) down to the basement and is also used for the venting of the side rooms and toilets.

In the time when cooling is required, the following physical feature used:

  • The warm air from the solar heating and heat dissipation of visitors rise to the top and is used in the heat pump to heat the remaining rooms of the museum , which at zero cost incurred refrigerant is used to cool the hall. Because the cold air is heavier, it spreads in the lower layer around the hall and creates a comfortable atmosphere.
  • A further highlight is that all the technology in the museum is invisible.

For cooling of diesel engines was only the adjacent pond available.

The living in the pond trouts were not to be disturbed by higher water temperatures. In addition to supplying the halls, the offices and apartments located in the neighborhood of the employees of Ruselkraftwerken the cooling water flows with residual heat in the small lake . There we installed a large fountain, the falling water in droplet form gave his heat in the air.
The event. Residual heat could be compensated by the water exchange between the lake and the upper reservoir. The function will be held as follows: The building on the right in the picture is equipped with pump and turbine. In the evening and during the period where the wake is running (see the hills in the background of the image) promote pump water to the upper reservoir. During the day, at times when peak load electricity is needed , the water flows back and generates peak load electricity in the turbine generator unit that is shown in the building in the photograph, is installed.
