Heat Loss from R-Value Calculator

Calculate Heat Loss





Formula

To calculate the Heat Loss (HLR):

\[ HLR = \frac{SA \cdot dT}{R} \]

Where:

What is Heat Loss from R-Value?

Heat loss from R-Value refers to the amount of heat that escapes through a material with a given R-Value, which measures the material's resistance to heat flow. This calculation is important for understanding the insulation properties of building materials and ensuring energy efficiency in homes and buildings.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ HLR = \frac{500 \cdot 30}{10} = 1500 \text{ BTU/hr} \]

The Heat Loss is 1500 BTU/hr.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ HLR = \frac{1000 \cdot 25}{15} = 1666.67 \text{ BTU/hr} \]

The Heat Loss is 1666.67 BTU/hr.
