摘要
建筑节水是城市地区节约水资源的重要方式,高校作为大规模公共建筑,其节水项目的实施将带来良好的外部性。为了定量研究公共建筑节水项目"节水减排"的外部性,基于外部性相关理论,首先界定了公共建筑节水项目外部性的定义,并运用费用效益理论建立了公共建筑节水项目外部性货币化的思路。其次,介绍了公共建筑节水技术体系,并推导建立了节水项目的外部性度量公式。最后对北京市某高校2016年用水量数据进行分析,结果表明:应用节水技术可以达到年人均节水量16.6 m^3,建筑节水率达到了42%;某高校节水外部性为476.56×10~4元,减污外部性为264.82×10~4元,总外部性741.38×10~4元,外部性的效益良好。
Building water saving is an important way to conserve water resources in urban areas,and the implementation of water-saving projects in universities as a large-scale public building will bring good externality. To calculate water saving and emission reduction externality of water-saving project quantitatively,the definition of externality of public building water-saving projects is firstly defined based on the externality theory,and the cost-benefit theory is applied to establish the thinking of externalities and monetization of public building water-saving project. Next,the water saving system of public buildings is introduced and the externality measurement formula for water saving projects is deduced. t In the end,the water consumption data of a university in Beijing in 2016 is analyzed. The results show that water saving technology can achieve the annual per capita water saving of 16. 6 m^3,and public building water-saving rate reached 42% with the use of water-saving technology. The water-saving externality of a university is$ 4. 7656 million,the externality of pollution reduction is $ 2. 6482 million,and the total externality is $ 7. 4138 million,and the externality benefits are good.
