Viewed from the social status of the importance of energy saving building

As we all know, building energy efficiency is a very wide range of
covers systems engineering, is also a difficult long-term project, and
reasonable to reduce energy consumption and protect our limited
resources and building a conservation-based society, is already a
subject of our employees work closely on The importance of building
energy conservation, I think in general the following three aspects can
be analyzed and described. First, the international energy analysis.
Second, the status of building energy consumption. Third, the status of
building energy-saving technologies.
Within the world of oil, coal, natural gas consumption in China
accounted for more than 30% of the 11,515 barrels of oil around the
world, that can supply only 40 years of mining, natural gas, the first
half of the twenty-first century, to dry up. 2040 oil consumption is
expected to reach its peak in 2050 the special man to the high cost of
phase sound energy, solar energy, wind energy, so the energy crisis is
an objective reality.
To analyze the status of construction, with the city's rapid
development, building energy consumption increased substantially and
became the subject of human consumption. Our society as a whole
building energy consumption has reached 32% of total energy
consumption, annual energy consumption of building materials, 13%, both
reaching 45% of the existing building area of ??40 billion square meters
of data shows that this data is not very accurate, but to illustrate
from the aggregate, most of the high energy consumption. 2020
construction area will reach 70 billion square meters, a huge building
energy consumption has accounted for most of our.
At the peak of construction, especially the large volume of Guangdong's
economy, is also a great amount of construction in each of the new
housing will be 20 million square meters, more than all the developed
countries, the amount of integrated building, of which more than 90%
The buildings are high energy, our energy-saving technology is
relatively backward.
In 1996, China had announced the Energy conservation design standards,
the State Council and Ministry of Construction are as important to the
way last year, the Ministry of Construction has several documents one
after another, all for building energy-efficient, and gradually improve
the building of high energy consumption . The level of architectural
design, building materials used with the Western developed countries
there is a big gap. Therefore, to carry out building energy efficiency,
has a very urgent practical significance, but has a very important and
far-reaching significance.
