Abstract：The paper studies not only the energy-saving effect of high permeability type Low-E glass in the northern part of Henan province, but also simulate and calculate the air-conditioning system and heating system load of some office buildings equipped with ordinary and high permeability type Low-E glass by applying DeST software.The result shows that the high permeability type Low-E glass is appropriate in the region.After the high permeability type Low-E glass being used, the cooling load, heat load, cooling consumption and heat consumption respectively drops by 10%, 26%, 3%, 41% through a whole year, compared with ordinary glass.Therefore, energy-saving has a great huge potential.
