If the special design is not provided, Shall not conduct construction drawing review and construction drawing stage review; The main building design unit shall summarize the relevant special designs, and specify the index of each special design drawing and the main relevant special requirements in the construction drawing design of the main building. Special design contents related to ultra-low energy consumption buildings shall be implemented in interior decoration.

The heat transfer coefficient of the main wall of the external wall of the building heating and air conditioning room shall not be greater than that of the non-heating and air conditioning room. The heat transfer coefficient of the main wall of the external wall of the heating and air conditioning room on the first floor and bottom of the building shall not be greater than that of the external wall of the heating and air conditioning room on the other floor.

10. The average heat transfer coefficient of building exterior wall is less than 0.4W/ (m·K). The unit type curtain wall is adopted for the enclosure type curtain wall, and the proportion of the corresponding facade area is not less than 80% of the surface area of the enclosure type curtain wall, and the unit standardization rate is not less than 70%.

11. When solar photovoltaic power generation system is used in ultra-low energy consumption building projects, roof photovoltaic modules or facade photovoltaic modules should be rationally arranged according to solar shielding analysis. When setting up energy storage systems, fire audits should be conducted and operational strategies for generation, storage and electricity consumption should be defined.
