According to Beijing “ 915 ” period builds energy-saving development program, began in June 2004, beijing takes the lead in releasing the 3rd pace in the whole nation energy-saving of 65% " living building is energy-saving design standard " , according to this one energy-saving requirement, build architectural area to heat up index to should accord with 32 W/m² .

When natural gas calorific capacity is pressed by thermal efficiency of 8400 Kcal/m³ , gas fired boiler 86% plan, and by the design temperature of the computation outdoor takes normative Beijing winter- 9 ℃, the average temperature outdoor takes winter- 1.6 ℃, indoor heating designs temperature to take18 ℃, heating period takes 125 days (be likeOn November 14To second year on March 18) when, computation gives this kind of throughout the country below highest and energy-saving standard, air consumption of floor area of heating period unit is 32×24×125×0.86&***ide;8400&***ide;0.86× (18 ＋ 1.6) &***ide; (18 ＋ 9) ＝8.3m³/ M² . And investigate discovery actually, the construction before Beijing has a lot of ten years and did not do any energy-saving transformed civil structure unit area air consumption is less than now7m³
