High-tech eye on energy use

By Dong Zhen  |   2008-9-4  |  

POWER-USE monitoring devices will be installed in all government offices and major public buildings in Shanghai in the next two years to cut energy consumption, officials said yesterday. 

The plan was unveiled yesterday as city officials signed contracts with scientists and engineers who will work on the latest 14 major research projects - the second batch of key scientific projects that is part of Shanghai's 11th Five-Year (2006-2010) Plan. The first batch of 24 projects was launched in May 2007. 

Scientists working on the projects are expected to provide critical technologies to be used in the construction of the city's major infrastructure systems, its environmental protection effort and future urban traffic network. 

A system to trace the use of power inside large buildings has been developed by a local science institute.

"The tracing system is expected to generate categorized outcomes of a building's power consumption, such as electricity used for air conditioning and lighting by the various departments inside," said an official with the Shanghai Construction and Transport Commission. Trial use of this technology has already begun inside a dozen large public buildings. 

As the technology gradually improves, authorities will install the monitoring systems in all local government office buildings and other structures that have floor areas exceeding 20,000 square meters. 

The results will provide data that will help authorities develop effective regulations and curb unnecessary power consumption, officials said. 

By 2010, the city hopes to reduce its annual power use by 20 percent. 

Large office buildings and shopping malls have become a major drain on China's electricity supply, using 10 to 20 times more power than residential buildings. 

Also under the city's R&D efforts, another project will focus on developing new technology to create effective models for Shanghai's villages to process their waste water.
