physics project?

Question

ok so a have this physics project and i need to desine a solar heating system to heat my house and it's not working out so well
first i need to find the R value of my housebase on this

windows
total area 14,913 in2
R value=1.61

doors
total value 3,804 in2
R value =2.17

walls
Total area 19,385.4 in2
R=13.73

please show me show to do this so i can do well on my project

Answer 1

the R value has dimensions of
{area x thickness x temperature difference / heat loss}
for example R = ft²·°F·h/Btu
The first thing you need to do is get everything in the same units
Then the heat conductivity U=1/R and
heat loss = area x thickness x temperature difference x U
You may have already included the thickness in your value for R

Answer 2

R value times area in square feet I beleive gives heat loss.
