One of this measures it the selection of modern glass layers for windows shielding the interior from Infrared Light while still ensuring proper transparency for light rays in the visible spectrum. Heat transmitted via heat radiation is reduced to 15 % through the installation of a modern 3-layer-windows compared to a single layer window.<\/p>\n<p>In combination with accurate insulation of windows and doors to minimize convection as well, this will lead to significant energy saving. The American council estimates that air conditioning costs can be reduced by 3 -5 % for every degree Celsius not needed to be cooled down. Considering that the comfortable living and working temperature for humans is around 20 \u00b0C and the average temperature in Vietnam is raging from 24 \u00b0C (Hanoi) to 27 \u00b0C (HCMC) the installation of proper insulated windows can lower the energy consumption significantly. Depending on the overall environmental conditions as the annual average temperature, sun hours per day or the configuration of the building, the payback time of the investment varies. A scenario from Austin, Texas (around 20 \u00b0C average) with the given temperature distribution estimates the payback time of the installation of modern windows\u00a0 to one year and to 10 years if existing window are replaced. In Vietnam this payback time is estimated to be even shorter.<\/p>\n<p>Besides the reduced energy costs and corresponding savings in resource consumption, the installation of modern windows also increases the appearance and the value of the premise.<\/p>\n<p><em>\u00a0Admin GCTF<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In tropical countries as Vietnam Ventilation and Air Conditioning of buildings is a necessity to provide livable and workable conditions for people and electronic equipment.
