Energy-saving renovation
( A ) reduce the use of aluminum decoration
Aluminum is the largest metal smelting energy products. Reduce 1 kg decoration aluminum, energy saving of about 9.6 kg of standard coal, 24.7 kilograms of carbon dioxide emissions accordingly if the country each year about 20 million home renovation can do it , then the energy savings of approximately 19.1 million tons of coal , 494,000 tons of carbon dioxide emissions .
( 2 ) reduce the usage of steel decoration
Steel is a residential renovation one of the most commonly used materials , steel production is energy-intensive carbon emission hungry. Reduce 1 kg steel decoration , energy saving of about 0.74 kg of standard coal , corresponding to 1.9 kg of carbon dioxide emissions if the country of about 20 million per year home decoration can do that , then can be saving about 1.4 million tons of coal , 38,000 tons of carbon dioxide emissions .
( 3 ) reduce the use of wood decoration
Appropriate to reduce the use of wood decoration , not only to protect the forest , increasing the amount of carbon dioxide absorption , but also reduces the wood processing, transport energy consumption. Least 0.1 cubic meters of timber decoration , energy saving of about 25 kg of standard coal, the corresponding emissions 64.3 kg of carbon dioxide and if the country each year about 20 million home renovation can do that , then you can save energy about 500,000 tons of standard coal, 1.29 million tons of carbon dioxide emissions .
( 4 ) reduce the use of architectural ceramics
Make use of ceramic home decoration house more beautiful , but also a waste of this , and partly renovated luxury home even in the presence of the phenomenon. Saves one square meter of building ceramics , energy savings of approximately 6 kg of standard coal , corresponding to 15.4 kg of carbon dioxide emissions . If the country each year about 20 million home renovation can do that , then you can save energy about 120,000 tons , 308,000 tons of carbon dioxide emissions .
农村住宅使用节能砖
与粘土砖相比,节能砖具有节土,节能等优点,是优越的新型建筑材料.在农村推广使用节能砖,具有广阔的节能减排前景.使用节能砖建1座农村住宅,可节能约5.7吨标准煤,相应减排二氧化碳14.8吨.如果我国农村每年有10%的新建房屋改用节能砖,那么全国可节能约860万吨标准煤,减排二氧化碳2212万吨.
合理使用空调
(1)夏季空调温度在国家提倡的基础上调高1℃
炎热的夏季,空调能带给人清凉的感觉.不过,空调是耗电量较大的电器,设定的温度越低,消耗能源越多.其实,通过改穿长袖为穿短袖,改穿西服为穿便装,改扎领带为扎松领,适当调高空调温度,并不影响舒适度,还可以节能减排.如果每台空调在国家提倡的26℃基础上调高1℃,每年可节电22度,相应减排二氧化碳21千克.如果对全国1.5亿台空调都采取这一措施,那么每年可节电约33亿度,减排二氧化碳317万吨.
(2)选用节能空调
一台节能空调比普通空调每小时少耗电0.24度,按全年使用100小时的保守估计,可节电24度,相应减排二氧化碳23千克.如果全国每年10%的空调更新为节能空调,那么可节电约3.6亿度,减排二氧化碳35万吨.
(3)出门提前几分钟关空调
空调房间的温度并不会因为空调关闭而马上升高.出门前3分钟关空调,按每台每年可节电约5度的保守估计,相应减排二氧化碳4.8千克.如果对全国1.5亿台空调都采取这一措施,那么每年可节电约7.5亿度,减排二氧化碳72万吨.
