The most common reference is the R-value, or the resistance to heat flow. The higher the R-value of a material, the more it will restrict heat loss or gain. U-factor (sometimes referred to as U-value) is a measure of the flow of heat (thermal transmittance) through a material, given a …

(The equation used to calculate heat gain or loss is: q = mc(T. A positive value for q indicates a heat gain while a negative value for q indicates a heat loss. (Acid—base neutralization is an exothermic process, so the water will experience a heat gain and therefore the temperature will rise.)

Calculating Heat Loss/Gain: To calculate heat loss (or gain), the following formula will be used:, where. Q' is the heat loss in Btus per hour (Btu/H) U is the reciprocal of the R-Value, A is the area of the surface ∆T is the difference in temperature on either side of the wall. You may round the transmission load to the nearest whole number.

These can be used to calculate the Heat Gain or Loss through the surface. Composite surfaces are constructed by the user from a library of materials and displayed in two or three dimensions. In addition, 2-D plots of Outdoor and Sol-Air Temperatures, Radiation variables, and Heat Gain/Loss through the envelope can be displayed.
