The building sector in Greece presents a huge energy saving potential, the largest part of which is remaining unexploited. The recently enacted legislation for the energy performance of buildings, in combination with the financial support provided by funding programmes to low income families is expected to significantly boost the deployment of energy efficient technologies in the Greek domestic sector. The exploitation of these legal and financial instruments follows a formalised process of energy audits, resulting in buildings classification and in the submission of Energy Performance Certificates (EPCs) including suggestions to improve the dwellings' energy performance. The paper aims at an ex-ante evaluation of the market trends revealed by EPCs in Greece, in order to identify the perspectives of individual technologies and to assess the degree to which the certification procedure helps in improving the energy performance of buildings. The results indicate a strong trend towards less cost-effective technologies, revealing a sub-optimal allocation of financial resources and putting into risk the path towards the achievement of EU targets for 2020. 相似文献

With the high growth urbanization and increasing new urban population, the huge demand for infrastructures and dwellings has become a great challenge for the sustainable development in Chinese cities. The building sector shares one fourth of total energy consumption in the country and plays an important role in reducing the energy consumption and the consequential green house gas (GHG) emissions. Some policies have been issued for promoting the low carbon sustainable development in China's buildings. However, existing barriers especially the investment barriers substantially prevent the low carbon technologies and service from being employed effectively. The carbon trading scheme of cap-and-trade is now widely accepted as one cost-effective way to deal with the climate change issue in the world, and it can be utilized for overcoming the barriers to carbon reduction activities in China's building sector. A new Clean Development Mechanism (CDM) energy performance based method is designed for reducing transaction costs in implementing CDM projects in China's buildings before 2020. And then a “step by step” approach is formed to establish the domestic and international carbon trading mechanism to effectively reduce GHG missions in China's building sector after 2020. 相似文献

加快我国合同能源管理发展的思考 总被引:2,自引:0,他引:2
合同能源管理是运用市场手段促进节能的服务机制,积极推进合同能源管理是完成节能降耗任务的一个重要措施。我国应通过完善政策、税收扶持、金融服务等加快推进合同能源管理的发展。由于合同能源管理在我国发展的历史还比较短、产业发展还处于转型升级阶段以及节能降耗的技术水平还不高等原因,需要我们付出更多的努力来促进合同能源管理在我国的发展。 相似文献

Public energy performance policy and the effect on diffusion of solar thermal systems in buildings: A Dutch experience 总被引:1,自引:0,他引:1
Energy performance policy is an important element in the European Energy Performance of Buildings Directive (Directive 2002/91/EC—in short: EPBD, published 4 January 2003), which the European Commission is now urging all European member states to introduce for the building sector by 2006. One of the expected benefits of energy performance policy is that it can help to introduce innovations such as solar thermal systems. However, few studies have analysed this so far. This paper describes the extent to which the penetration of solar thermal systems in the residential building sector is directly related to energy performance policy in the Netherlands. The concept of energy performance policy is explained and the effects of using energy performance policy for several years in the Netherlands are described, through the results of an empirical study. Statistical analysis appears to show no association between Dutch energy performance policy and the application of solar thermal systems in the domestic sector. 相似文献
