Overview

The PC-program CRAWL calculates the crawl-space temperature and relative humidity for the cases of outdorr and indoor air ventilation. The heat loss through the floor structure is also calculated. Both the heat loss variation during the year, including the peak effect, and the accumalated heat loss during the heating season are given.

 

The PC-program  SLAB calculates the heat loss to the ground  from an evenly insulated rectangular slab on the ground. Both the heat loss variation during the year, including the peak effect, and the accumulated heat loss during the heating season are calculated. 

The results are based on heat conduction in a semi-infinite ground with homogeneous soil. The effect of moisture movements or changes in moisture content is not considered.

The PC-program CELLAR calculates the heat loss to the ground from a rectangular building with a foundation of the cellar type with constant insulation thickness at the floor and the wall. Both the heat loss variation during the year, including the peak effect, and the accumulated heat loss during the heating season are calculated.

The results are based on heat conduction in a semi-infinite ground with homogeneous soil. The effect of moisture movements or changes in moisture content is not considered.
