Cultural-Tourist Complex “Chengene Skele”
nZEB Example

The external walls are of double construction with intermediate air layer, gypsum boards
Glasroc, reinforcing mesh, plaster, mineral plaster, internal thermal insulation of mineral
wool with thermal conductivity = 0,039 W/ mK and internal plasterboard lining.
To ensure the necessary microclimate parameters of the building are used individual local heat pump air conditioning split systems of direct evaporation, column and wall type.
Domestic hot water will be provided by a 50 litre electric boiler. The water heating mode is automatic according to the set minimum temperature for switching on the heating element and maximum temperature – for switching off.
The hall is equipped with a general exhaust and discharge ventilation with a flow rate of 3000 m3/h. It is implemented in a “top-up” scheme by means of 1 recuperative unit with temperature efficiency E≥70% and electrical power 1,95 kW, mounted in the suspended ceiling and a system of air distribution and exhaust grilles mounted directly on the ducts.
