| Based on green building evaluation index system, carbon emissions in whole life cycle of Tianjin Sino Singapore eco city low carbon experience center and carbon reduction potential of adopting main green technologies in the operation stage were calculated and analyzed by using eFootprint software. The results showed that the largest proportion of carbon emissions in the operation stage of this building was 89.74%, followed by the materialization stage, which was 10.08%, the abandoned stage accounted for only 0.18%. At the same time, the utilization of solar water heating technology had the best carbon emission reduction effect on buildings, with CERR of 15.27%, followed by the green technology of energy saving lighting, with CERR of 3.13%. In this case, the application of water saving measure and ground source heat pump not only failed to achieve the effect of emission reduction, but also increased carbon emissions compared with those without these technical measures. |
