Economic Benefits Analysis of Building Glass Film in “Information Sharing”
First, the characteristics of building glass film
Building glass film, also known as building glass insulation anti-explosion-proof membrane, is a high performance polyester film directly applied to the glass surface of the building, which is produced in the United States in the 1960s, which is mainly used to control glare from the sun. Heat. Today, the building glass film has been developed for more than 40 years, and its performance has been very stable. After loading the building glass film, ordinary transparent glass will become a combination of heat, environmentally friendly, anti-theft, explosion-proof, anti-break, anti-high temperature, anti-UV line, etc., safe insulation, light transmissivity and clarity It will not be affected. At the same time, the glass film is very secure and glass bonding, under normal conditions, 10 to 15 years will not fall off, and the service life is relatively long. In addition, existing glass film is in building doors and windows and glass curtain wall energy-saving modifications, more fast, economical, environmentally friendly, safe, and, and installation is also faster. Therefore, the building glass film has become a comprehensive performance of improving the comprehensive performance of the glass and improves the efficiency of building energy utilization efficiency.
Second, building glass film self-economic benefit analysis
Some experts conducted a special topic for “energy-saving and safe glass film”, and the research content is two “comparative test analysis”. First, the anti-impact strength, aging resistance, optical performance, UV performance of the glass film is compared; two, the film glass room and the insulation and energy saving performance of the ordinary glass room are compared. The comparative test results of the insulation of the insulation indicate that the outdoor temperature is 3.5 ° C in the room temperature of the room with the film glass in the room. The film glass can block more than 95% of the solar ultraviolet rays, and it can also enhance the glass toughness and impact strength, reducing the no reason for the glass to people. The results of the air conditioning power test show that two 16 square meters of rooms under the same conditions are 0.24 degrees with a room with a film glass. There is authoritative calculation and analysis showed that the air conditioner consumption can save 435 yuan per month after using a glass film, the air conditioner can save 435 yuan before using a glass film, the air conditioner can save 435 yuan per month before using a glass film. Save electricity consumption of 1305 yuan.
Third, architectural glass film and energy saving
Economic Benefits Analysis of Glass Because there are only 30% to 45% of building heating energy consumption, 30% to 45% of building heating energy consumption is wasting through doors and windows. In terms of how to improve the energy saving of the building doors, the relevant experts believe that “the focus of existing building energy-saving transformation is the transformation of doors and windows, and the glass transformation is the top priority of energy-saving work.” There are two ways to choose from the transformation of existing buildings doors and windows. The cost of changing the energy-saving glass is compared to the cost of the thermal insulation film, which can be found that the cost of the glass film is lower than the cost of changing energy-saving glass. Take the transformation of the existing residential building door and window glass in Shandong Province, the material cost of replacement of ordinary houses is replaced with 12 mm hot reflective coating tempered glass, and the material cost of hot reflective coating tempered glass is 120 yuan per square meter ~ 160. Yuan, the cost of the old glass disassembly is 40 yuan per square meter, and the total transformation fee is 160 yuan to 200 yuan per square meter. If the thermal reflective film is used, the material cost is 100 yuan per square meter to 130 yuan, and the charge fee is 30 yuan per square meter, and the total transformation fee is 130 yuan per square meter to 160 yuan. By comparison, the cost of the thermal reflective film is only about 80% of the thermal reflection glass cost. According to the “Eleventh Five-Year Plan” period during the “Eleventh Five-Year” period of Dongying City, there are both residential building energy-saving and modification, using a glass film than replacing energy-saving doors and windows up to 40 million yuan.
