Part 2-1 of project: R-values and overall thermal conductance of building materials

Part 2 of the project will consider a standard size (1000 sq. ft.), 2-bedroom, one story home with no basement. The group chose Iowa City as the location. (If you don't bleed black & gold...)

1. List the R-values of the building materials and compute the overall thermal conductance (UA) of the home.

When calculating the R-values of the building materials, some assumptions of the types of materials that were used had to be made. These are reflected in the table below

The overall thermal conductance was calculated using the general equation UA= (1/Rvalue)*(Area) for each total R-value and summing up those terms. The total R-values and total areas are shown in the table below.

*The floor of a slab home needs to be considered for sizing a furnace but not an air-conditioner.
