| Abstract |
A web-based interface is developed to easily evaluate the impact of seasonal changes of Leaf Area Index[LAI] on energy performance in buildings with green roof using the EnegyPlus and Python. The results obtained from simulation are compared with the case which LAI was set to fix during the simulation period. The values for fixed and seasonal varying LAI were referring to previous literatures. According to the results, relatively lager LAI in cooling season could lead to the reduction of cooling load in the building. Relatively smaller LAI in heating season could lead to reduction of heating load in buildings. The consideration of seasonal changes in LAI showed lower heating and cooling load than the fixed LAI did. Thus, LAI values that differ from climate, region, and growing season should be carefully selected to achieve accurate evaluations of the energy performance of buildings with green roofs. Also, the energy saving results could be evaluation according to the various design of green roof, types of buildings and so on using the developed interface. |
