1. What is the difference between R-value and U-value? When are they used?
R- value meaures resistance to the transfer of heat, and U-value shows how much heat is allowed through. They are inversely proportional. R-value is used to rate insulation, whereas U-value is used to determine how much energy it will take to heat or cool a space.
2. What are some leading causes of solar gain?
lack of proper insulation, dark roofs absorbing heat
3. What key areas of a building can minimize heat loss?
walls, roof, floor
4. Why is a cost estimate important to create before starting a project?
so you can put a budget on the project
