Attic Temperature Calculator

Formula

The formula to estimate the Attic Temperature (AT) is:

\[ \text{AT} = \text{OT} \times (1 + \text{SG}) \]

Where:

\( \text{AT} \) is the attic temperature (°F)
\( \text{OT} \) is the outside temperature (°F)
\( \text{SG} \) is the solar gain factor (dimensionless, ranging from 0 to 1)

What is Attic Temperature?

Attic temperature is the temperature within the attic space of a building. It is influenced by the outside temperature and the amount of solar radiation the attic receives, which can significantly increase the temperature inside the attic. Understanding attic temperature is important for proper insulation and ventilation to prevent heat-related issues and improve energy efficiency.

Example Calculation

Let's assume the following values:

Outside Temperature (OT) = 85 °F
Solar Gain Factor (SG) = 0.5

Using the formula to calculate the Attic Temperature:

\[ \text{AT} = 85 \times (1 + 0.5) = 85 \times 1.5 = 127.5 \text{ °F} \]

The Attic Temperature is 127.5 °F.
