关于节能,你一定要知道这些

如果要说起这几年的世界性公共话题,节能必定首当其冲。在全球节能减排的大趋势下,更多看不见的领域才是真正的『能源杀手』。

 

以建筑领域为例,中国目前建筑量占全球的40%,已经成为了世界上最大的建筑市场,并且每年以『再造一个中国』的速度增长。


Energy saving has been a heated global issue in the recent years. Some invisible areas have become the real “energy killer”. In the construction sector, for example, China currently accounts for 40% of the global construction, which has become the world's largest construction market.


但中国的公共建筑由于管理粗放,成为了浪费能源的样板,其能耗比西方发达国家高出一倍。比如重庆、上海、深圳市级办公单位,分别耗电132度、139度、117度,均高于纽约的66度,德国的67度。这说明中国的大型公共建筑基本上都是耗能非常高的建筑。


However, the energy consumption in China doubles the figure in western countries. For example, the power consumption in Chongqing, Shanghai, and Shenzhen is 132 degrees, 139 degrees and 117 degrees respectively, which is much higher than the energy consumption in Germany-67degrees, and New York-66 degrees. It shows that the large public buildings inChina are basically heavy energy consumption.


在设计阶段全国95.7%的建筑是节能的绿色建筑,但是在竣工后真正是节能建筑的仅有53.8%。

At the design stage, 95.7% buildings are energy efficient buildings, while only about 53.8% of the buildings are really energy efficient after completion.


那么,什么才是真正适合中国国情的节能减排方案呢?

So, what is the appropriate energy saving solutions for China?


让我们算一笔账:以典型的80年代办公楼(窗户面积950 m²)为例,能耗单位kWh/(m²a)。更换优化了隔热性能(达到被动房水准)的旭格75.SI窗系统后节省的能源是每年24,500升燃料油,二氧化碳排放量减少65吨。这约等于驾车430,000 km或环绕地球10次产生的能耗。


Primary energy consumption in existing buildings, using a typical 1980s office building as an example with a window area of 950 m², energy consumption in kWh/(m²a). Replacing the windows with Schüco Window 75.SI⁺ with optimized thermal insulation (passive house standard) results in an annual saving of 24,500 litres of heating oil and spares the atmosphere from absorbing 65 tonnes of CO₂ per year. This is roughly the equivalent of driving a car 430,000 km or around the world 10 times.

旭格,打造更加适合中国的节能方案,为更多的中国建筑提供最高品质的节能服务。

Schüco makes the best energy saving solutions for China.
