AWDABPT Buildings version a3.2

The program calculates the average room air temperature under the given climatic and room thermal load conditions. A heat transfer analysis is performed dynamically over the required time period of up to twenty days. Finite difference numerical methods are used so that the thermal storage effect of the building structure is properly modelled. A proper solar radiation generator, based on the model for the equation of time and the solar declination, is used. The solar radiation received on a surface can be varied by selection of its solar absorptance (absorption factor), the turbidity factor (haze) of the air and the cloud cover. Re-radiation from external surfaces to the sky is also modelled. Convection and radiation heat transfer coefficients are calculated during the running of the program at each time increment. The convection coefficients are determined depending on temperatures as we
