Study On The Implementation Framework Of Energy-conservation Audit For Large Public Buildings

Almost all Chinese large public buildings are energy-inefficient, making large amount of greenhouse gases and particulate matter emissions, exacerbating the greenhouse effect and haze. How to use limited energy to achieve sustainable economic development under strict environmental requirements, has become a major issue facing our country. One effective way to solve this problem is the energy-conservation audit, but the audit has not been carried out. In this context, it is necessary to carry out studies on large-scale public building energy audit and establish a practical implementation framework to promote energy-conservation audit.Based on the theoretical analysis, this paper uses the questionnaire to survey audit experts from different levels government departments across the country, around the large public building energy-conservation audit. The implementation framework should be adjusted according to the needs of the audit. This study aims to address the key issues, "Who will audit", "What to audit " and "How to Audit".Firstly, the paper collates and reviews the significance of large public buildings energy-conservation, history of the development of energy regulation and current situation of domestic and foreign research, summarizes the important role of energy saving and shortcomings of the existing building energy regulation work.Secondly, the article points out the large public buildings have some characteristics like high energy inefficient, large energy-saving potential and public properties and so on, delimits the concept of large public building energy-conservation audit to analysis the differences between it and energy assessment, building energy audit and green building assessment.Then, based on the theoretical analysis and surveys, the paper constructs the organization system of large public building energy-conservation audit, mainly using the power of government audit institutions, supplemented by internal audit department and social institutions. The paper also analysis the necessity and feasibility of government audit institutions to carry out large public building energy-conservation audit.Large public building energy efficiency issues is a public problem, throughout the whole life cycle, preliminary design influencing the late running. Under the request of comparability, importance and cost-effective, the paper makes design and operation management as the focus of audit and establishes eight main content of the audit system.Under statutory, unity and the principle of objectivity, the paper summarizes three kinds of auditing standards: the generally accepted principles, national regulations and industry standards, trying to make initial construction of audit standard system.Large public building energy-conservation audit is very difficult, but the government audit insufficient doesn’t have enough strength. So, the paper presents two kinds of audit model: independent audit and audit outsourcing.In this paper, we make study on large public building. This kind of building seize small proportion of construction area but high energy consumption. It can make great contribution to energy industry to construct the implementation framework of large public building energy-conservation audit. However, due to the limited level of professionalism and the lack of practice tests, the implementation framework needs more research.
