A wall 2 cm thick is to be constructed from material that has an average thermal conductivity of 1.3 W/m•C. The wall is to be insulated with material having an average thermal conductivity of 0.35W/m•C, so that the heat loss per square meter will not exceed 1830W. Assuming that the inner and outer surface temperatures of the insulated wall are 1300 and 30 C, calculate the thickness of insulation required.

One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose a single-story cubical house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, by what percentage would the heating cost of the house drop? Take the house to have dimensions 10 m by 15 m by 3.0 m.
