建筑节能

Building Energy Efficiency

每户家庭 60%-70% 的能耗用于取暖及 制冷

Heating and cooling take up 60%-70% of

energy consumption every household

美国每年通过建筑节能措施可节约相 当于 3 千亿度电的能源 In the U.S., energy equivalent of 300 billion

KWh is saved through building energy

efficiency measures every year.

美国每年通过建筑节能措施可减少 6 亿吨的二氧化碳排放 In the U.S. , 600 million tons of CO2 emission could be reduced through building energy efficiency

measures every year.

无论制冷还是制热，热阻从 0.53 提高到 1.23 m2∙k/w 可以使能耗费用节省 40 ％ Increasing thermal resistance from 0.53 to 1.23 m2∙k/w can save 40% energy cost, whether for heating

or cooling

无保温 No insulation ：房屋围护结构表面温度很低，空调效率低，感觉寒冷Housing enclosure surface temperature is very low; Air conditioning efficiency is low; feeling cold

保温对于建筑，就象羽毛对于企鹅、毛发对于北极熊。 Insulation for the building is just as feathers for the penguins, hair for polar bears.

According to JGJ134-2001 “Design Standard in Districts with Hot Summer and Cold Winter “, to meet the energy target of 50% of energy consumption in Shanghai: 采暖耗电量： 31.2 千瓦时 /m2/ 年 Heating power consumption: 31.2 kwh / m2 / Year 空调制冷耗电量： 26.6 千瓦时 /m2/ 年 Air conditioning power consumption: 26.6 kwh / m2 / Year

一些换算公式 Some conversion formula ： 统计资料表明： 1 度电 ≈ 0.4 千克标准煤；另外：一个单位的标准煤≈ 2.493 单位的二氧化

碳排放 Statistics show: 1 kWh ≈ 0.4 kg of standard coal; a unit of standard coal ≈ 2.493 units of CO2 emissions
