Heat Loss Calculator

Step-by-Step Guide to Using the Heat Loss Calculator

Introduction

The Heat Loss Calculator is a tool designed to estimate the heat loss from a building based on various input parameters. This guide will walk you through each step of the process to ensure accurate calculations.

Step 1: Enter Surface Areas

Begin by entering the total areas for each component of your building:

• Total Wall Area (m²): Enter the total area of the walls in square meters. Make sure this value is greater than or equal to 0.
• Total Window Area (m²): Provide the area of the windows. This should also be a non-negative value.
• Roof Area (m²): Input the roof’s area in square meters.
• Floor Area (m²): Enter the total floor area, ensuring it is at least 0.

Step 2: Set Temperature Values

Next, input the temperatures relevant to your calculations:

• Indoor Temperature (°C): Enter the temperature inside the building. This value should be between -50°C and 50°C.
• Outdoor Temperature (°C): Provide the outdoor temperature, ensuring it falls within the same range as the indoor setting (-50°C to 50°C).

Step 3: Select Insulation Types

Choose the insulation types applicable to different parts of the building:

• Wall Insulation Type: Select from poor (U-value: 0.5), standard (U-value: 0.3), or good (U-value: 0.2) insulation options.
• Window Type: Choose between single (U-value: 2.8), double (U-value: 1.6), or triple glazed (U-value: 0.8) windows.
• Roof Insulation Type: Options include poor (U-value: 0.4), standard (U-value: 0.25), and good (U-value: 0.15) insulation.
• Floor Insulation Type: You can select between poor (U-value: 0.6), standard (U-value: 0.35), and good (U-value: 0.2) insulation.

Step 4: Calculate Heat Loss

With all values entered, the calculator will compute the following:

• Wall Heat Loss: Based on your inputs, it calculates heat loss through the walls.
• Window Heat Loss: Provides the heat loss occurring through windows.
• Roof Heat Loss: Displays heat loss for the roof area.
• Floor Heat Loss: Calculates the heat loss through the floor.
• Total Heat Loss: The sum of all individual heat losses.

Step 5: Review Annual Energy Loss

Finally, the tool will give an estimate of the Annual Energy Loss in kWh/year, helping you understand the potential energy inefficiency over a year.

Conclusion

By following these steps, you can effectively use the Heat Loss Calculator to determine the heat loss of your building, enabling you to make informed decisions about improving insulation and energy efficiency.
