Apple Garden

Almaty, Kazakhstan

Apple Garden is an EPlus-Energie single-family house with a Weissensee wood construction and was built within 15 months from design to fully furnished handover in the mountains of Almaty.

The building has a complex building services concept and distinguishes between 3 different climate zones within the thermal envelope.
Fresh air is pre-tempered via a ground collector and fed into the controlled living space ventilation system with heat recovery, while also supplying an air source heat pump. The system is supported by thermal solar panels and a PV system with 20.55 kWp with an annual yield of 25,893 kWh/a, covering the building's own demand. To increase the self-sufficiency, an electric storage tank was installed. Heat is brought in via underfloor heating, and cooling in summer is provided by planar ceiling cooling.
