Low-e glass energy saving window will be universal
Warm in winter and cool in summer, this is common people on a basic standard of dwelling ideal. However the bedroom of your home could meet such effect, and of your home the window has the very big relations. You know, your annual heating fee of 80% of flowers in the window heat dissipation. The author understands, more heat preservation, the energy saving of the new Windows-Low reflective coating (low-e) glass or three bo two hollow, and other forms of energy saving window will be comprehensive popularization.
Eighty percent heating fee “forget” to the window “the window, the bigger the daylighting, the better the house was more warm. Especially the French window, sunshine house full, some energy saving.” For the resident so common ideas, liaoning province building materials science institute ZhuYingBao chief engineer with a set of figures show that his attitude: building outside the window with daylighting, ventilated take a breath, heat preservation a variety of functions, but building outside the window is also called the building insulation transparent black hole. Because of the loss of external Windows heat transfer 30%, air exchange heat loss is occupied 50%, the window of heat loss for 80% of the total housing heat loss. With 100 square meters of housing for example, according to every square metre heating fee every year 21 yuan calculation, equivalent to the households in the $1680 a year from the Windows and threw them…….
“Especially French window and single glazing, heat loss is the biggest. Some building the single glass French window, although look glass is very thick, but heat preservation rate is almost zero.” Shenyang is built appoint a professionals said.
“Automobile coating glass” will now homes residents choose what kind of the window is energy-saving warm? Expert introduction, in recent years, from the Windows of the country can reflect shenyang construction energy conservation work progress. Shenyang to building energy efficiency of reform of the window is divided into three stages, 1991 in 1996 to in, aluminum alloy Windows instead gangchuang; In the 2005 years ago, instead ofaluminium alloy window of model steel window; From March 1, 2006 up, the newly built residential building executive shenyang place standard “residential building energy saving design standard, common single box double glass window of model steel window can not meet the third step to energy saving, LOW reflective coating (low-e) glass or three bo two hollow, and other forms of energy saving window will be comprehensive popularization. “This glass of similar car coating windshield, thermal insulation, heat preservation, prevent bask in the effect is very good.” Experts said.
At present, shenyang has compiled by the national first cold area of residential building energy saving 65% design standards, in 2010, shenyang new residential building energy saving rate by 50% now will be increased from 65% to. ZhuYingBao said: “in the power saving construction energy conservation rate increased to 65% after, further improve the the heat preservation function of the window is very important.” The curtain of your home is energy saving?
Make ZhuYingBao chief engineer, unfortunately, in the north of China, energy-saving building outside the heat preservation function of the window is not cause enough attention of citizens (southern window sunshade is already on energy saving design standard). Almost all of the curtain of the residents are not for energy saving and purchase. If the heat reflecting membrane, heat reflection foil made to heat preservation and heat insulation, decoration multifunctional curtain, will make thousands easily realize warm in winter and cool in summer.
“In construction on the use some heat preservation material is a good bargain!” In the author ZhuYingBao calculate a bill: or to a 100 square meters of housing, for example, every square metre heating fee $21, the use of 50 years, total heating fee is 105000 yuan. If use the money to strengthen the building of 1/5 of the thermally insulated, the family can save at least 30000 yuan of heating costs (by building energy saving rate is 50% computation), still can save 16.2 tons of BiaoZhunMei state.
