According
to the Shanghai Research Institute of Building Sciences in Shanghai this year,
some public buildings and residential buildings energy research and statistics,
Shanghai has been surveyed more than 16,000 buildings all public buildings and
some 40,000 buildings typical residential buildings , electricity 55.6 billion kWh, which is about
3.25 billion kwh air conditioning energy consumption , accounting for 58.5% of
building energy consumption . Survey
data also show that Shanghai has a lower air-conditioning equipment efficiency
of 80% using public buildings and residential buildings , and high energy
consumption .
Certification
by the state departments and agencies recognized municipal EPRI built the first
based on the latest energy efficiency standards for energy-saving
air-conditioning equipment performance testing laboratory , which is currently
in east China 's first refrigeration , air-conditioning industry testing product
range over the full third-party inspection agency
. According
to the latest " acceptance of energy efficient building construction
(GB50411-2007)" provides that prior to the laboratory in the new building
completion and acceptance of all kinds , air-conditioning must be 2% of the
sampling equipment, testing their compliance with the latest national energy
efficiency standards .
EPRI
test data from the city to build air-conditioned laboratory showed that under
the same cooling or heating effect , the use of high efficiency , low-power
air-conditioning equipment than low efficiency, high energy consumption
year-round air conditioning equipment can reduce building HVAC energy consumption by 15% -20 %.
