Abstract
This paper described the validation of the ventilation net work model for the estimation of the room temperatures and heat loads of residential buildings with the results obtained by measuring the three test houses. The air tightness of the three test houses were measured using a pressure method and the ventilation rates were measured by CO_2 tracer gas method. The ventilation rates were calculated with measured wind direction, wind speed, ourdoor temperature, room temperature and air tightness. The results of comparison between the calculation and the measurement showed good agreement within allowable range of error. Using the air flow velocity measured at the doors the room to room air flow rate were estimated and compared with calculated heat flow rates. The results showed the good agreement. Therefore, it was concluded that the ventilation net work model could be used for the simulation of the room temperatures and heat loads of residential buildings.
