In recent years, the mainstream of relevant studies in China mainly focus on co-
benefits policies of GHG emissions reduction and energy saving at
national or local (e.g. province and city) levels in China (He et al.,
2010; Xu and Masui, 2009; Aunan et al., 2004; Cao et al., 2008).
Very few works have been given the attention to specific sectors
such as the building sector. Therefore, there are no definitions of co- benefits that have been made to the building sector. This study puts
the focus on assessing the energy use and carbon emissions and
exploring the approach of achieving the effectiveness of co-benefits
in China's buildings.
