AWDABPT Underground Enclosures version a3.1

The program calculates the average enclosure (room) and entrance tower air temperatures under the given climatic and room thermal load conditions. A heat transfer analysis is performed dynamically over the required time period of up to a year (if you have the computer capability available). Finite difference numerical methods are used so that the thermal storage effect of the enclosure structure and the surrounding soil is properly modelled. The ground thermal properties together with the long term average air temperatures at the enclosure's location are used to estimate ground temperatures over a twelve month period. Actual ground temperatures for a given day at given depths may also be used to help shape the ground temperature model. That is, you can adjust the soil thermal properties to gain a better fit of the temperature curves. A proper solar radiation generator, based on the model
