Design parameters of the building envelope energy-saving potential sequencing and recommended values.

Design parameters of building envelope	Sensitivity coefficient			Sorting	Recommended values
	Maximum	Minimum	Average
The comprehensive heat transfer coefficient of the exterior wall	0.0120	0.0099	0.0111	5	≤0.5 W/(m^2·K)
The comprehensive heat transfer coefficient of the roof	0.0013	0.0009	0.0011	6	As small as possible, if the criterion is met
The comprehensive heat transfer coefficient of the external windows	0.0385	0.0318	0.0352	3	As small as possible, if the criterion is met
The solar heat coefficient of the outer window	0.0207	0.0118	0.0166	4	0.3795 W/(m^2·K)∼0.44 W/(m^2·K)
The ratio of the window to the wall	0.0481	0.0354	0.0416	2	As small as possible, if the functionality is met
The airtightness of the outer window	0.0496	0.0457	0.0474	1	The higher the level is, the more feasible the technology and economy are. The recommendation is above level 4
