Chapter 5: CONCLUSIONS and RECOMMENDATIONS5.1. conclusionThe contractor conducting energy efficiency survey in 45 buildings in Pasig city and 5 works in Hai Phong city at the request of the project. Thus, reviews the situation using the energy in each of the works.Through surveys, reviews in the works, we can know the status of management, energy use in the buildings in Vietnam. From there create the premise of helping managers in the construction of the system of national data base on the use of energy efficiency in the construction and progress to build Benchmarking for other kinds of works. At the same time it is also the basis to help the agency manage the given solutions, consistent policy aimed at promoting the use of energy savings and efficiency in the construction work in Vietnam.The process of implementing the contract, the contractor has met a number of favourable and difficulty as follows:*) Advantages:-The interest, help from Winrock International, Ministry of construction, the construction of Hanoi and Haiphong in obtaining access to the server (or a management unit) works.-Survey in the works are a combination of enthusiasm from the server (or a management unit) works in providing the necessary information.*) Difficulties:-The authentication of the work were difficult due to other causes: list of works by Winrock International offering initially with wrong name, address, many of the works management units, etc.; Some have agreed to join the project but the deployment process lacked the necessary information such as architectural drawings, mechanical drawing, ...-In the course of the survey, because of the security requirements of information should a unit number is not for image capture information about architecture and a number of devices using the dedicated power sides. From the survey results, the contractor has a number of reviews are as follows:-The level of energy use in the different works depending on the elements: purpose, scope and functions of the works; the equipment energy use in buildings; the number of users in the process; the structure, the architecture of the buildings.-Current works often tend to switch to energy-saving equipment such as: T5 Lamps, LED lights, air-conditioning systems VRV central air-conditioning, local labeled energy. -Improving the efficient use of energy through the architectural structure of the works almost as much interest yet. This is manifested through the wall and roof insulation structure has not yet been made, the glass door and glass still use more glass 1 class, ...-The management of energy use in different work types: In the hotel building (BC05, BC06) and commercial center (BC12) usually are of interest and perform much better than the other type; Energy management in construction enterprises management, private investment is often better than the works.
