Sustainable Urban District Environment Evaluation Method Research

In recent years, with the rapid development of urbanization in China, the human living behavior, and economic behavior on urban environment and uncontrolled development have a negative impact on more to the already resident environment. And as the future urban development is the most important city venues and outdoor space-the urban ecological environment in the whole city blocks and micro climate has a direct impact, but also its for urban residents has important significance to improve the environment and energy saving residential whole city.For green ecological city construction green building blocks to be used as the basis, but the building is not only green blocks needed to support the theory, but the need for systematic evaluation system to be bound and guidance.This paper takes Germany enacted in 2012 DGNB new environmental quality in urban district sustainable evaluation system evaluation system as the basis, combined with China's actual construction environment and climate characteristics, compare china-German Green system for systematic comparison of the evaluation criteria identified in the time-scale green building extends to neighborhoods lacking in content, and to develop a core of research methods and content.In-depth study, according to the German advanced evaluation system and the relevant literature, focusing on proposed evaluation methods and calculation methods adapted to our urban neighborhoods full life cycle carbon emissions, the establishment of a typical calculation model and make calculations and evaluation, according to the calculation and evaluation results summed up China's urban neighborhoods carbon reduction measures. In addition, according to this article in the German district evaluation system of solar energy utilization efficiency and building layout, protection, protection of soil and water resources, biodiversity three scale expansion of green building standards lack of content, through case presentation and analysis, suitable for our country evaluation methods.The entire article in the latest release of the German green district evaluation system as the basis, focusing on the feasibility and necessity to adapt to a standard of green building rating scale expansion in china, and focus on for the scale extends to district lacking a content for our green building blocks, improvement and development of the evaluation system and lay a foundation.
