Foreword This analysis develops a model with an energy simulation tool for a typical floor of an office building in Shanghai. It simulates and compares the energy consumptions of HVAC (heating, ventilation, and air conditioning) of an office floor installed with different types of glazing, single glazing, LowE insulating glazing and Low-E vacuum insulated glass. Dr. Kuei-Peng Lee, Department of Energy and Refrigeration and Air Conditioning, National Taipei University of Technology, was appointed to conduct this analysis. Dr. Lee is an acknowledged expert on building energy efficiency and participated in many major LEED certification projects in Taiwan.http://www.77cn.com.cn

HVAC of the Office Building The air conditioning system of this office building is chilled-water central air conditioning system. There are two scenarios for heating system, natural gas boiler system and electric heating system. The climate data of Shanghai is excerpted from U.S. DOE website and the original data is from National Meteorological Center of China.

Energy Simulation Software eQUEST, a dynamic energy consumption simulation software, is used in this analysis. The software is based on DOE-2, a widely recognized building energy analysis program that predicts the energy consumption for all types of buildings. DOE-2 uses a description of the building layout, construction, operating schedule, conditioning system and utility rates along with climate data to perform an hourly simulation of the building.http://www.77cn.com.cn

Conclusions (2/2) The above mentioned results only calculate the energy savings from the improvement of building envelops. The cost saving results from the reduction of the related facilities, such as HVAC, is not included. On the other hand, because the thickness of VIG is much less than that of IG, the amount and weight of window frames/accessories can be reduced. Therefore, the loading of the building structure will be reduced. If the building is designed with VIG, the cost of the building structure materials can be decreased.http://www.77cn.com.cn
