Building energy use still takes big part

The building construction sector still plays a big role in China's energy consumption mixture as the country continues to make efforts to achieve its urbanization target, said a government official on Monday.

"The energy issues are hard to solve during the country's urbanization process," said Han Aixin, deputy director-general of the buildings department for science and technology and energy saving at the Ministry of Housing and Urban-Rural Development during the 2012 China Planning Network Annual Conference.

According to figures from the ministry, at present, building energy consumption accounts for about one-third of the total social energy consumption in the country. The other two big consumers are industry and transportation.

He said the ubiquitos energy network - a network combining energy supply, information communication and electricity trading - will be the way to solve urban energy problems.

ENN Group, a private Hong Kong-listed Chinese energy company, has established an eco-community in Qingdao, Shandong province, applying the ubiquitous energy network.

"The network helps community residents adjust their energy consuming behavior to save energy day by day," said Gan Yongqing, vice-chairman of ENN. "The network can also be applied in the industrial sectors."

However, Han said more should be done to calculate experiences with the network.
