HVAC & R Network A few years ago, which use high-tech base ceremony domain environment-friendly residential building integrated solar technologies, advanced energy-saving air system and modular bathroom drainage Water Technology, and carefully build up the heart of this boutique real estate capital, the carbon seems very far away from the people's attention. But now, when the green, green [link widoczny dla zalogowanych], carbon is becoming a real estate development theme, we have to admire the project design and builders of unique vision.
Low-carbon housing is like? It is understood that, in fact, "low-carbon home" is not a very fresh concept. In the construction sector, on the low carbon buildings have long been clearer definition: low-carbon construction is the building materials and equipment in manufacturing, construction and building construction for use throughout the life cycle, to reduce fossil Energy Use, energy efficiency, ultimately reducing carbon dioxide emissions.
Experts told the author that there is a saving of 20% of the energy can lift, down the elevator car when the kinetic energy into electricity, which requires the delivery of goods, and it is then converted into kinetic energy; there is a Ground Source Heat Pump System [link widoczny dla zalogowanych], the heat can be ground into the room. Simple to understand, is that in winter we geothermal heat in the "take" out, the supply of heat to the interior and provide domestic hot water; in the summer, the indoor heat "get" out "emissions" to the ground, so ground-source energy efficient heat pump system has the advantage.
"Light is natural, heat from the ground 'dug' out of the house or even a wood structure ... ... These elements may be low-carbon homes will see you soon." Experts say this to the author.
The general trend of low-carbon housing
In the "low carbon building" and "Low Carbon Economy" before the advent of China's construction is still in a absolute "carbon building" phase of development. Have a data that new housing construction in urban and rural areas in China each year nearly 2 billion square meters area, of which 80% were high energy consumers. Nearly 40 billion square meters of existing buildings, over 95% of high-energy architecture, construction energy consumption accounts for 40% of the total energy consumption in China, Building energy efficiency Become the focus of energy saving.
Data showed that China's heating [link widoczny dla zalogowanych], air conditioning, ventilation, lighting energy consumption accounts for about 30% of the total energy consumption, researcher's conservative estimate is that by 2010, emissions in China increased 600 million than in 2000 tons. The professional research also showed that carbon dioxide emissions from buildings account for 40% of global emissions.
However, the United Nations Climate Change Conference in Copenhagen in Denmark before the opening of the Chinese government has made it clear that by 2020 China's carbon dioxide emissions per unit of GDP than in 2005 40% -45% decline. Obviously, if the energy consumption of houses and buildings can not be effectively down to effective implementation of the Chinese government has recently made commitments to the world very difficult.
Provincial capital low carbon residential houses?
The author notes, both from last year CIHAF, or just the end of this year's two sessions, for strengthening the exploration and construction of low-carbon housing calls for a low carbon economy has been growing, "low-carbon building" has been in Beijing, Shanghai, Guangzhou, Chengdu, Hangzhou and other cities burgeoned. Then the capital of the real estate sector, the trend in the face of this big, what kind of action will occur then? Those who work hard to explore the real estate business, which give the concept of low-carbon, the capital of three big change in the
