Influence of external venetian blind shading and LSG of insulating glass on optical and thermal comfort
For the five climate regions in China,Comfen was used to simulate and quantify the impact of 15 modes for vene-tian blind shading on the energy density and comfort level of south-facing hotel external shading under four kinds of LSG.The results show that the energy consumption demand for heating,cooling,ventilation and lighting varies greatly in different climate re-gions,and the building energy consumption and indoor comfort affect each other.The condition of venetian blind shading and LSG of insulating glass have a great impact on the indoor heat gain and sunlight illumination,and further affect the building energy consumption and indoor comfort.The condition of venetian blind shading and LSG of insulating glass are obtained when the total energy consumption density,thermal comfort and light comfort are respectively optimal in different climate regions.The CRITIC weighting method was used to obtain the weight coefficients of building energy consumption density and indoor light and thermal comfort level in each climate region.Furthermore,the comprehensive scores of different working conditions and the optimal scheme are obtained,
