Low carbon economy development, is China's "twelfth five-year" plan for determining an important task, is actively explore green low carbon development road suitable to China's national conditions, the effective ways to promote the economic development mode change, is also an important means of strengthening work on climate change.

L2, 2009, aims to solve the problem of global warming the UN climate change conference in Copenhagen, China solemnly promises: to 2020 unit of gross domestic product (GDP) of carbon dioxide emissions 40% ~ 45% lower than in 2005. The 12th five-year plan of the country also clearly puts forward the goal of energy conservation and emission reduction. Low-carbon economy becomes a major subject of China's construction intensive society and an important guideline for China's economic construction.

According to figures from the ministry, China's urban and rural construction each year new housing construction area of nearly 2 billion square meters, more than eighty percent of energy construction, the existing 40 billion square meters have 95% more for high energy consumption in building construction. At present, our country has exceeded the total energy consumption of building energy consumption by more than 30%, according to the international experience and China's current building that can predict the level of development, in 2020, our country building energy consumption accounts for the proportion of the total energy consumption in the whole society will reach 35%, become the first big social energy consumption. The 50% of the energy consumption of buildings is lost through doors and Windows, and the proportion of glass in doors and Windows accounts for 70% ~ 80%. In the case of industrial glass and the use of glass for transportation, only building glass, the proportion of the total energy consumption of the whole society has exceeded 10%. According to the authoritative data, the annual energy consumption of the glass Windows in China is about 225 million tons of standard coal, equivalent to the annual generating capacity of 21 three gorges hydropower stations.

At the same time, the haze problem caused by energy consumption pollution seriously restricts the social ecological civilization construction and human habitation health. In this severe situation, the research and promotion of low-carbon building technology and its integration is of great significance. It is imperative to accelerate the development of passive low-energy buildings, green buildings and green energy-saving materials represented by vacuum glass.

The most advanced energy-saving buildings

Passive low energy consumption building technology refers to: the passive energy saving technology to building palisade structure optimization, maximum limit to improve the heat preservation, heat insulation and airtight performance of buildings, and through the fresh air system of high efficiency heat (cold) recycling equipment will indoor hot (cold) in the exhaust recycling, thereby significantly reducing the need for building heating and cooling. Through the use of self heating and ventilation, natural lighting, indoor heating source, solar radiation and achieve comfortable indoor temperature, humidity, maximum limit to reduce reliance on active mechanical heating or cooling system
