Thermodynamics: Insulation

The video tutorial discusses the inefficiencies of an old house and explores ways to improve its efficiency. It introduces the U-value equation, which measures the conductivity of materials, and explains its components: power, area, and temperature change. The tutorial then introduces the R-value, the inverse of the U-value, used by contractors to assess building efficiency. Practical methods to enhance house insulation, such as adding fiberglass and reflective materials, are discussed, demonstrating how these changes can significantly increase the R-value and reduce energy costs.

What was the initial R-value of the house and what is the new R-value after improvements?

What steps can be taken to improve the efficiency of a house?
