- Heating climates (cold regions): Showed that the space conditioning requirments increases with colder temperatures, decreased floor space, and increased glazing ratio. Higher R-value decreases heating requirements (exponential decay). By not accounting for thermal bridges the heat loss may be up to 84%. | - Heating climates (cold regions): Showed that the space conditioning requirments increases with colder temperatures, decreased floor space, and increased glazing ratio.

- Cooling climates (warm and hot regions): Showed that the space conditioning requirments increases with warmer climates, incresed floor space, and increased glazing ratio. Higher R-value decreases cooling requirements (exponetial decay). Cooling shows similar results to heating but not as dramatic. | - Cooling climates (warm and hot regions): Showed that the space conditioning requirments increases with warmer climates, incresed floor space, and increased glazing ratio.

- States that increasing the insulation thickness becomes less effective if Thermal bridges are not accounted for. There is a point at which increasing the R-value has little effect as shown in the results from the results from the whole building energy simulation. | - States that increasing the insulation thickness becomes less effective if Thermal bridges are not accounted for.
