Study On The Energy Consumption Quota Of Medical Buildings

The function of medical buildings is complicated, and the environment is strict, so the energy consumption is much higher than other public buildings. At present, the research on the energy consumption index of medical buildings is relatively few. Therefore, the paper used the research data, software simulation, theoretical analysis, data processing methods and so on, then gives the energy consumption quota of different types of hospital buildings.Firstly, according to the function of medical architecture, the medical architecture is divided into general hospitals and specialist hospital, special hospitals, recuperation and rest homes and so on. Then according to the medical building energy type of equipment to build up the medical building classification and medical building be divided into HVAC, lighting, medical equipment, office equipment, steam and hot water, elevator, restaurant and drainage system and other eight categories.According to a hospital in Shandong province for the status quo analysis, get all kinds of medical building energy index and the proportion, analysis the factors affecting medical building energy consumption. HVAC, medical equipment, food and beverage and steam heating energy consumption accounts for a larger proportion of the energy consumption is the main influencing factors influence, and mainly related to the building function and the size of the building. HVAC energy consumption is also related to the air conditioning system, and gives that the water-cooling unit, air cooling unit, heat pump and LiBr absorption chiller is having different heat and cold sources of energy consumption indicators,so energy consumption index of different types of systems are different. The main influence factors of office lighting, elevator and other part of the energy consumption is the number of people. The survey data can be seen that different types of medical building energy consumption index of these parts is not very different.Dest simulation software simulates the energy-saving and non energy efficient buildings of different enclosure structure (exterior walls, windows and roofs). Different conditions building impact the energy consumption, and the types of medical building load is mainly affected by the impact of local climate and building envelope. Retaining structure is different, thus affecting the heating, ventilating and air conditioning energy consumption, reflecting for building energy-saving and non energy saving building energy consumption's difference.Finally, analysis of statistical quota method and technology quota method's advantages and disadvantages, through the comparison and selection based on the investigation data, adopt the quota statistic of probability in statistics method, and get the energy index of different types of hospitals, four types of hospital building energy consumption quota refers to the corresponding cumulative probability varied with the different standard.This index can be used as the basis for the evaluation of medical building energy consumption, but also provides a reference and advice for the energy conservation of the medical building.
