Impact of Building Architecture to Thermal Comfort Level a Case Study at University of Moratuwa, Sri Lanka

Lumped Mass Thermal (LMT) model was used to evaluate the net heat gain to the building through solar heating, internal heat generation Effect of the building orientation, cross ventilation and special architectural aspects such as courtyards, grill design etc were evaluated using the same model Hourly dry bulb temperature, wet bulb temperature, humidity level and solar irradiation level of the two buildings throughout the day were taken to validate the modelfield study was carried out based on ASHRAE 55 standards with 50 selected occupants in each building
