The formula to calculate the Relative Heat Gain (RHG) is:
\[ RHG = (US \times 14) + (SC \times 200) \]
Where:
Relative heat gain is a measure used to determine the amount of heat gained by a building or space due to external factors such as sunlight and shading. It helps in understanding the thermal performance of a building and is crucial for designing energy-efficient structures.
Let's say the summer U-value (US) is 0.5, and the shading coefficient (SC) is 0.3. Using the formula:
\[ RHG = (0.5 \times 14) + (0.3 \times 200) = 7 + 60 = 67 \, F \]
So, the relative heat gain (RHG) is 67 F.
