In recent years, more and more attention to energy conservation throughout the world, as it relates to the whole social-economic sustainable development, building energy saving and reduction was one of the most important things. With China's rapid economic development, the construction of large public buildings increasingly rapid, the building energy construction should be sufficient attention.A large public building construction, from design to completion will involve all aspects of the use. The project construction period is characterized by long, complex functions, professional wide, construction difficulties, at the same time to proceed from these energy management can achieve better building energy conservation. Building energy consumption, the air conditioning system, energy consumption accounts for a sizeable proportion, so that, in this paper, Tianjin Railway Station Rebuilding Project, ventilation and air conditioning and fire from the professional point of view, from the design and construction to operation management, energy conservation awareness and application of a detailed analysis. Tianjin Station project introduced by the air conditioning system, heating, cooling mode, ventilation and smoke exhaust of the program, fire system design and operation management. The various design proposals will be selected to determine the optimum system, analysis of the design of mitigation benefits and disadvantages, and construction, supervision and building energy-saving features of the combination. In the inside environment of comfort to meet the conditions, to further reduce the building energy consumption of the technical approach.Purpose of this paper is to combine theory and practice, to talk about the large public construction projects on energy saving building management applications. Through the analysis of Tianjin Railway Station redevelopment project of energy saving, the energy-saving building still shows greater potential for public building energy efficiency and control of social energy consumption provides some reference value. |
