The electronics retail store with parking spaces on the ground floor of the company "TechnoDom" is a special project, because it is located in an extremely cold climate zone (-35/+34) and is the first building in the city not to have a state district heating connection, although it is located in the center of Karaganda.
Karaganda is a well-known place for the Kazakh coal industry.
With this project, the client Eduard Kim (founder and owner of TechnoDom AG) and NEUBAU best.energy wanted to realize a lighthouse project and prove that business buildings (electrical trade) can also achieve the highest efficiency.
Compared to a standard Kazakh shopping center of this size, TechnoDom saves 645 tons of CO2 per year.
At the opening on 17.02.2022 at -21°C outside temperature in Karaganda, TechnoDom was sufficiently heated due to the optimized building envelope with internal heat sources (customers and equipment).
Heating and cooling is provided by a probe array with 41 deep probes with the length of 80 to 100 meters and two cascaded heat pumps.
Electricity is produced by the PV system on the roof with the power of 253kWp and covers about 73 % of the own annual demand.
