Indoor thermal environment
1. Effective measures should be taken to improve the thermal performance of the building envelope, to prevent discomfort caused by excessive or low temperature of the inner surface of the external wall and window, and the influence of solar radiation heat entering through the glass window.
2. Indoor temperature and humidity parameters should be designed reasonably, and natural ventilation should be considered to improve indoor thermal comfort. The openable area of the external window should meet the requirements of natural ventilation and ventilation.
3. The area of skylight (excluding atrium) should not be greater than 5% of the total area of building roof, the heat transfer coefficient should not be greater than 3.2w/(m2 k), and the glass shading coefficient SC should not be greater than 0.5.
4. The heat transfer coefficient of the transparent part of the atrium should not be greater than 3.2 W/(m2 k), the glass shading coefficient SC should not be greater than 0.5, and the visible light transmittance of the transparent part should not exceed 0.6. Natural ventilation should be fully considered in the atrium of the building, and mechanical ventilation should be set when necessary.
5. Doors should be set outside or measures should be taken to reduce cold air infiltration.
6. Encourage the use of adjustable external shading facilities.
7, air conditioning heating system should be designed with humidification and dehumidification function; And set an appropriate control mode.
8. The air distribution mode should be designed reasonably, and the heating and air conditioning mode of radiant ceiling, radiant floor or floor air supply should be encouraged when conditions permit.
