The architectural design allows for the house to be ventilated mostly through passive ventilation. On a hot day, the cooling system can guide the surrounding airflow around the roof to reduce the indoor-outdoor heat exchange, and thus lower the indoor temperature; on a cold day, a heat storage system in the roof can warm up the indoor area.
Additionally, we incorporated fresh an air heat-exchanger to improve the indoor air quality with minimal energy consumption.
The sun provides all the energy for River Sunvelop, which equipped with 10.3kw PV system. In order to achieve the goal of BIPV PV system is integrated with tiles and eaves. Meanwhile grid connected PV power system will become demonstration for community grid in the future.
Heat can be adjusted appropriately with the application of phase change heat storage roof and intelligent ventilation system of River Sunvelop. The system could lower the temperature and store the sun's heat during the day and provide power at night. We use the heat of the back sheet of PV panels, minimizing energy consumption.
Daylight illumination introduces sunshine with solar tube and filters high-heated infrared. Scientific natural lighting design together with smart and human-oriented lighting control contributes to smart, comfortable and energy-saving light environment.
The warm experience comes from three sources：solar water heating system, waste heat recycling system and air source pump system. Efficient air source heat pump converts 1kWh electricity to 3 kWh heat. River Sunvelop recycles waste heat emitted by the air conditioner in summer and reduce energy consumption.
Environmentally friendly HVAC system use inverter technology, helping reduce power consumption. It creates cool indoor environment in summer and warm in winter. In addition to warm air, the system improves thermal comfort experience by floor heating during the winter.
