Investigation and Study on the Energy Consumption of Large Scale Commercial Buildings in Nanning

As one type of the public buildings and compared to other types of public buildings,large scale commercial building features higher energy consumption density for unit surface area and large amount of electric power consumption,and thus has great potentiality for energy-saving due to its larger building areas,various energy consumption devices,highly dense stream of people and longer running hours,etc.Based on the statistics and auditing of the energy consumption for the large scale public buildings in Nanning,the energy consumption of the large scale commercial buildings are analyzed from the aspects of operating conditions,air-conditioning systems and illuminating systems.The study of energy-saving strategic was also conducted from the aspects of building envelope,system devices and energy management.
