Abstract

In recent years, in order to promote the construction of low-carbon communities (LCCs) in China, many scholars have proposed an evaluation indicator system of LCC. The existing indicator systems are mostly established from the macro perspective of environmental impact and resource conservation, but few are from the micro technical perspective. Thus, the aim of this study is to construct a micro technical evaluation indicator system for LCCs. Firstly, the index system was divided into three categories: low-carbon building, low-carbon transportation, and low-carbon environment. Then, the technical indicators were selected through empirical analysis. The indicator weights were assigned by the improved analytic hierarchy process (AHP) and the multi-level fuzzy comprehensive evaluation method was used as the evaluation method of the indicators. Finally, in order to examine the practicality of the indicator system, two typical communities in Tianjin and Shanghai were selected as case studies. The results showed that the indicator system gave a reasonable low-carbon level for the two communities, which was in line with the actual low-carbon construction status of each community. In addition, the evaluation results pointed out that the low-carbon community (LCC) in Tianjin needs to further strengthen the construction of the low-carbon environment, including community compactness, rainwater collection and utilization, and waste recycling. For the LCC in Shanghai, it was pointed out that the construction of the low-carbon building and low-carbon transportation needs to be strengthened. The indicator system can be used as a tool for urban planning and construction personnel to evaluate the construction progress and low-carbon degree of LCC.

Highlights

In recent decades, with the rapid development of different countries, global carbon emissions have increased rapidly [1,2]
According to the research on the current development status of low-carbon communities (LCCs) assessments, all the main indicators related to LCCs, green ecological community, and sustainable community are defined in this framework
The study established a technical evaluation an index system low-carbon and the relevant technical indicators of LCC construction were selected through empirical ties

Summary

Introduction

With the rapid development of different countries, global carbon emissions have increased rapidly [1,2]. The increasing carbon emissions have increased the pressure on natural systems and resources, which directly leading to global climate change and the deterioration of the ecological environment [3]. The rapid urbanization process is one of the main factors leading to the increase in carbon emissions. As the most basic unit in urban construction, the urban community is the main space carrier of human life, entertainment, and industrial production, and the main carrier of urban carbon emissions [5,6]. Low carbon research at the community level is the foothold of the implementation of low-carbon urban planning strategies, and plays a role in improving the low-carbon technology of single buildings [7,8]. How to build an LCC has become a research hotspot in many countries
