Clicking on the floor icon on the program's main form provides access to selection of floor material. It also provides the facility for defining the 'position' of the floor I.e. Ground floor or intermediate floor.
When Ground floor is selected the program will automatically enter temperature and heat transfer coefficients for the sub-strata under the floor construction. Overall calculation accuracy would be little enhanced with user functions for altering heat transfer coefficients for varying under floor sub-strata. The burden of extra key presses and functions is therefore omitted from standard issues of the program. Users may however elect to over-ride program default and enter their own ground temperature.
When Intermediate floor position is selected the program sets the temperature under the floor to be as Ambient. Users may however elect to over-ride this program default and enter their own under floor air temperature.
