To achieve the goal of saving 15%
construction GDP on average RMB 10,000
and up to saving 20% as final goal,
a large number of new materials and
new technologies have been applied to
new building construction and existing
building renovation in Shanghai. A series
of new initiatives for energy-saving
construction are being actively promoted
in Shanghai, including energy saving
building sites, reduction of operating
costs in public buildings and energy
contracting. |
| |
|
| |
In the Eleventh Five-Year Program,
130 million square meters of new buildings
and 50 million square meters of residential
and public buildings will comply to
energy-saving standards, and 30 million
square meters of existing construction
will be renovated accordingly. |

Energy conservation in new
residence |
| |
|
| |
For example, "Dahua Chinese Parasol
Tree City", a total construction
area of approximately 380,000 square
meters, includes residential buildings
and public buildings, all integrating
insulation measures. |
| |
|
| |
All windows are using 27mm Low-E glasses,
it is not only for keeping warm also
can reduce noise. In addition, solar
water heating devices was installed
in the whole residential area. Solar
photovoltaic systems are running on
an experimental basis on commercial
buildings. |

Renovation of existing buildings |
| |
|
| |
In renovation project of De Yi Yuan
Changde Rd, 253 million Yuan was invested
by the government for the facades, renovation
of roofing. It is about RMB 56 yuan
per square meter of renovating. After
the renovation, there is about 24kWh
per year can be reduced on every square
meter. Based on 0.61 yuan per kWh of
the existing tariff in Shanghai, the
cost of renovation can be recovered
in 4 years. |

|
| |
Extension of energy saving |
| |
|
| |
Establishment saving site is an extension
of the directions. Lower operational
cost of energy construction is another
extension. Shanghai will promote renewable
energy in buildings. In the Eleventh
Five-Year Program, there will be around
2.5 million square meters completed
in use of solar energy. |
| |
|
| |
With regard to large and medium-sized
high-energy consumption public buildings,
Shanghai is now introducing advanced
energy management contracting. In the
Eleventh Five-Year Program, 65 million
square meters public buildings will
be the focus of the implementation of
advanced energy management. |
