Abstract

With rapid socio-economic development and the fast progression of urbanization, at present, China has become the world's largest energy consumers and carbon dioxide emitters, whose environment and resource faces enormous threatens and challenges. It is imperative that effective measures be taken to solve this problem. Green building in China has surely got a favorable development momentum over recent years, Assessment standard for green building (GB/T 50378-2014) (China Academy of Building Research, 2014) has been widely used in the evaluation work of the green building. In this paper, the case phase Ⅱ construction project of JDXG (Lingping, Hangzhou, China) has been rated as two-star green building by the standard. This project used plenty of green technology in energy conservation, water conservation, raw material conservation, land conservation and environmental optimization of interior space, and optimized the architectural design, which is expected to achieve significant effects, moreover, the green technology such as solar water heating system, spray irrigation system in landscape and high-ratio of green space would make significant contributions to carbon dioxide emission reduction in its life-cycle.

Abstract

Based on an extensive review of 31 international and domestic indicator systems, a system, which consists of 6 primary categories, 19 secondary categories, and 39 indicators is proposed for Transfer Science and Technical Park in Hangzhou city, covering sustainable development in environment, urban space and green building, transportation, energy and resource, governance and infrastructure, and economy aspects. Then all indicators are classified into three implementation stages (e.g. regional control indicators, park management indicators, and block control indicators) to ensure the fully accomplishment of low-carbon targets, which are always neglected by researchers, planners, governments and city managers. In the end, two scenarios are adopted, while the former is developing in traditional way and the latter is under the circumstance that all indicators are accomplished, to calculate the carbon reduction in order to quantitatively evaluate the effect of the indicator system. The results reveal that the policy makers should give the priority to indicators related to green buildings (e.g. ratio of green buildings), utilization of renewable energy, green transportation (e.g. mixed land use, green travel, green vehicles, etc.), greenery (green coverage ratio, multi-coat landscaping planting system etc.) while establishing policies and guidance towards a low-carbon eco-city.
