Technical specification for fresh air system of ultra-low energy consumption buildings

T/NAIC 001-2021

Chief editor: Zhejiang Dpurat Environmental Equipment Co., LTD.

Implementation date: May 1^st, 2021

The "Technical Regulations" is to standardize the design, construction and acceptance of the fresh air system of ultra-low energy consumption buildings in our country, so the fresh air system could meet the energy saving requirements of ultra low energy consumption buildings.

As a main part of ultra-low energy consumption building, fresh air ventilation system makes high efficient use of energy sources inside the building such as the body heat from the residents or household appliances heat – Keeping room temperature constant. Heat recovery efficiency can reach up to 75%.
