Mandatory provisions
3.0.3 residential buildings through the use of enhanced heat insulation properties of building envelope and improve the heating, air conditioning energy efficiency energy-saving measures to ensure the same thermal environment 3.0.1,3.0.2 premise indicators, and not taken energy-saving measures than before, heating, air conditioning energy consumption should be saving 50%.

Article 4.1.5 of the shape coefficient style buildings should not exceed 0.35, the point should not be building shape coefficient more than 0.40.

4.2.1 outside the window (including the balcony door of the transparent part) of the area should not be too large. Different direction, different than the outer area of window to wall windows, the heat transfer coefficient should be consistent with the provisions of Table 4.2.1.
