Lulea Researchers helps China to climate smart construction

Published: 21 September 2015

Construction processes causes large emissons and energy leakage. Researchers from Luleå and a top university in China cooperates with big Chinese and Swedish construction companies in order to develop climate smart construction processes.

In China various construction processes account for 25 percent of greenhouse gas emissions. In Sweden it is estimated the construction sector's total climate impact equivalent emissions from all the cars in the country.

It is particularly during building process as large emissions and energy leakage occurs. Scientists from China and Lulea in cooperation with one of China's largest construction company and the Swedish construction companies NCC and Lindbäcks AB, will now develop methods to reduce the construction sector emissions and energy consumption.

We will develop practical methods for industrialized construction house project managers and developers and agencies in order to help them  evaluate energy consumption and emissions throughout the construction process. It can for instance be about to assess how the choice of insulation, transport with large diesel ships, selection of raw material or design solutions affect the climate, says Jutta Schade, project and construction researcher at Luleå University of Technology. Todayit is a lack of methodology to do comprehensive assessments.

Gren expertis from China

Researchers from the Chinese top university Harbin Institute of Technology, with expertise in green construction, and building researchers from Luleå University participates in the project. In China, there is a huge interest to reduce emissions and here Sweden is seen as a pioneer when it comes to these issues.

- Royal Swedish Academy of Engineering Sciences (IVA) and Swedish construction industry estimates that it takes between 20-85 per cent so called embodied energy in construction of a building, embodied energie  is the energy spent while building. Compared to the construction process the finished buildings are often relatively energy efficient. Many requirements that must be regulated in the construction processes, such as fire protection ie, often influence energy consumption in the end, says Jutta Schade.
