Ultra-low energy consumption building – Yaohai Residential Project

The residential project in Yaohai, Hefei City, Anhui Province, with an above-ground GFA of 9,852 ㎡, adopts passive and active technical measures for ultra-low energy design, covering building, HVAC, electrical and water supply and drainage aspects.

• Passive energy conservation: Compared to other energy-efficient buildings on the plot, the thickness of ternal wall insulation is increased by one time; external windows adopt triple-glazed double-cavity hollow windows with airtightness of Class 8; south-facing external windows adopt mid-mounted sun-shading windows, and the building is free from thermal bridges and airtightness treatment;
• Active energy conservation: Active energy conservation: The energy system adopts ground-source heat pump air-conditioning system, and at the same time, sets up a new air system with high-efficiency air purification and heat recovery functions, and the full heat recovery efficiency of the fresh air is not less than 70%.

At the same time, the project adopts technologies such as prefabricated building and full renovation design and construction to achieve the goal of healthy and green all-round high-quality construction while meeting the ultralow energy consumption building targets.
