Quality System
Production Design
The heat-cold supply of the building is performed from a heat pump with a ground circuit, which works together with the underfloor water capillary heating system, which is also intended for “gentle” floor cooling, covering (absorbing) heat emissions with a coolant temperature of +19-21°C.
Cold source for cooling the building – the ground circuit of the heat pump, consisting of water capillary mats embedded in a 150 mm thick horizontal composite reinforced concrete slab, under an insulated floor. This type of installation is suitable for buildings with low energy consumption and in cases where it is not possible to build an external circuit.
Standard ĢEO circuit consists of a network of wide “3-D” modules of water capillaries, which are mounted at a depth of 1.5 m.
The heat-cold power of the GEO circuit varies from 34 līdz 70 W/m2 (capillaries), depending on local conditions and type of installation.

Production Design
During the warm period of the year, the cold ground temperature (+8-12°C constantly) is “transported” to the floor capillary system and the ventilation unit pre-cooler (without the use of a heat pump compressor, only electronic circulation pumps). In this way, the ground circuit, which was cooled during the heating period, is heated during the summer, restoring the balance of thermal energy in nature. The annual SCOP can reach up to 8,9 W/W.
By taking full advantage of energy devices, it is possible to reach a level very close to the characteristics of a self-sufficient, passive house.
