Project financing of ESCO is the key link to conduct EEEB. The more scientific project financing strategies are affected by some inner factors, such as financial situations in a corporation and corporate business objectives, and involved by some external factors, such as project status, marketing character of energy saving service market and constraints by policy and law. From the analysis on reciprocal action between inner and external factors, financing cost, financing risk and income from investment are the three main factors to choose an appropriate financing mode. ESCO can implement project financing by enhancing enterprise competitiveness, improving the market climate and fostering a normative policy and law environment.

Government supervision in construction engineering quality (security) is the government enforcement supervision, whose seriousness, legality and authority cant live without normalization of supervision implementation content. We should ensure the standardization of supervision project and set up the standardization of supervision implementation methods, even guarantee standardization of supervision implementation result. The standardization of supervision project mainly includes supervision project category, supervisory object, all kinds of engineering entity supervise project and completion acceptance supervision etc; the standardization of supervision implementation methods mainly includes construction bodies report procedure and content, supervision information platform establishing, regulations of the random spot check and supervision tools etc; the standardization of supervision implementation result mainly includes standardization of table styles, supervision record reliability, supervision materials complete and clear, supervision results scientific dealt with and quality supervision report normative and rich etc. To ensure the validity of supervision via strict, scientific and effective supervision, it could achieve the scientific nature and purpose of government supervision procedure in construction engineering quality (security).

Government Supervision in Construction Quality Standardization is the intrinsic requirement of implement scientific supervision, which essential ends to standard surveillance behavior, improve efficiency and level of supervision and promote continuous improvement in construction engineering quality. Government supervision in construction quality standardization consists of three systems, including supervision process, decision and implement standardization. Construction of supervision process standardization and supervision decision standardization is theoretical connotation requirements of government supervision in construction quality standardization; Construction of supervision implement standardization is the inner rules of government supervision practice. supervision process standardization mainly involves three aspects: the chief of supervision, the content of supervision, the operation of supervision; supervision decision-making consists of expression standardization of supervision results, standardization of supervision decision-making and assessment standardization of performance evaluation. Supervision implement standardization consists of supervision program, supervision project, supervision mode and supervision achievements standardization.

Enhancing the guarantee of government supervision effectiveness on construction quality and intensifying the reform of supervision need continuous endeavors. Minister of Housing and Urban-Rural Development has established the Engineering quality supervision guidance ,based on basis principles on government supervision on construction quality of Supervision Rules on Construction Quality, which sets aims to refined and modern management .It proposes some new requirements about the government supervision on construction quality ,such as clearing demands of qualities, emphases and participants; planning projects in more scientific ways; refining supervision on quality behaviors; strengthening quality supervision on project entity; controlling strictly in project final acceptance; normalizing reports and files; and informationizing the methods to supervise. It is a consecutive task to improve efficiency in government supervision on construction quality, and guarantee successive improvements in construction quality.

Government supervision in construction engineering quality (security) is the government enforcement supervision, whose seriousness; legality and authority are on basis of an orderly supervision procedure. We should ensure the standardization of implementation plan for supervision early days and strengthen the standardization of implementation process in mid-term, even control the standardization of implementation results later period. To sum up, it includes handling supervision procedures strictly, choosing supervisory personnel scientifically, defining supervision scheme reasonably, informing supervision parts definitely, listening to the subject reports seriously, choosing selective examination project randomly, implementing site inspection, uploading supervision records timely, issuing treatment notice directly, completing supervision report form etc. To standard surveillance behavior via scientific and reasonable supervision procedure, it could improve the validity of monitoring and high efficiency, and achieve the scientific nature and purpose of government supervision procedure in construction engineering quality (security).

The standardization of government supervision in construction quality operation process is a driving force for the effective operation of government supervision in construction quality standardization system. It is core foundation is programming of supervisory operation process; the operating conditions is legislation of supervision conduction process; the basic mode is randomization of circuit supervision; the effective platform is information of means of supervision; the operating mechanism is dynamism of supervisory operation and management; and its substantial requirements is standardization of inner formation process of supervision dates

Standardization of government supervision process in construction quality is composed of standardization of the subjects of supervision, standardization of the content of supervision and standardization of the operation of supervision together. The essential of the subjects of supervision standardization to regulate quality supervisor in government, including six aspects such as specialize the supervision businesses, rationalize the supervision tasks, team ship supervision implement, crystallize the surveillance responsibility, the professionalization of qualification of the supervisor, and regular the training of supervision businesses; standardization of the content of supervision is core factor to operate the standardized system of government supervision in construction quality, including six aspects such as normalize the content of supervision work, systematize the key point of supervision work, unitize the form of supervision record, standard the system of supervision work, self-discipline of supervision behavior and legalize the supervision procedure

Standardization system of government supervision organizations for construction quality is standardized work procedures, standardized code of conduct and standardized system based on normalized working behavior, working process, working content, decision-making procedures, implementation measures and work results of government supervisory organizations for construction quality. Standardization system of supervision and decision-making is an important way to make government supervisory organizations for construction quality scientific, effective and authoritative. Not only does it require standardization of supervision decision, it also needs standardization of its support system and results form, videlicet, the expression standardization of supervision results and assessment standardization of performance evaluation. The essence of the expression standardization of supervision results is standardization of supervision files, unification of supervision and inspection forms, modeling of supervision information processing and sharing, formatted supervision report form and standardized of supervision conclusion expression; assessment standardization of performance evaluation includes comprehensive of performance evaluation on supervision, science of management evaluation on supervision market and dynamic of latter appraised on supervision project.

Improve the efficiency and scientific of government supervision working in construction quality is an essential for enhancing its effectiveness, government supervision in construction quality standardization is effective measures for improving supervision. The paper analysis the purpose carries out government supervision in construction quality standardization from two perspectives, including the chief part of supervision and the operation of supervision; and dissects a significance of building government supervision in construction quality standardization system from six aspects, including change the way of supervision, supervision development and revolution, improve supervision efficiency, mend supervision means, distinguish nature of supervision responsibility and the code of conduct of supervision. Based on internal demand and operating characteristics of government supervision in construction quality, constructing two systems which include supervision process and decision standardization; and decomposes the structure and interactive relationship between the systems. Realize government supervision effectively in construction quality through standardization.

Standardization of government supervision business decisions for construction quality is the core of scientific and effective operation of the standardization system of supervision decision-making which is in record to standardization of performance evaluation and assessment. The expression form of supervision business decisions standardization requires expression standardization of supervision results. The nature that the decision is based on should be legalized; the process of performing decisions should be scientific; the evaluation that decisions sustain should be generalized; the decisions of completion for the records sparkplug comprehensive; the form of evaluation and decision-making should be standardized.

The healthy and stable development of energy efficiencies in existing buildings cannot be separated from effective policy operation, and evaluating policy effective- ness contributes to scientifically-sound government deci- sion-making. This paper creates an evaluation index system and a grey comprehensive evaluation model for policy effectiveness for energy efficiency in existing buildings using three dimensions: 1) the effect of the policy itself; 2) the administrative effect of the policy; and 3) policy implementation effects. It chooses the government's subsidy policy and preferential tax policy at market cultivation stage for its empirical comparative evaluation. The evaluation indicates that the former is more effective. Finally, it puts forward policy development suggestions from the perspective of: 1) clarifying incentive object; 2) broadening incentive scope; 3) increasing incentive intensity; and 4) innovating incentive mode.
