About the Passive House Savings Calculator

The Passive House Savings Calculator is a dedicated tool in our Ecology category designed to help you estimate energy savings from passive house design in seconds. By automating the underlying mathematics, this utility eliminates manual calculations and provides reliable, instantaneous estimations.

Mathematical Principles & Calculation Steps

To compute the results, the calculation engine processes your custom inputs: House Area (sq m), Standard Energy Use (kWh/sqm/yr), Passive House Energy Use (kWh/sqm/yr), Electricity Price ($/kWh). Specifically, the calculations are evaluated using the standard relationship: savings = standard - passive. All computations are performed locally within your secure browser session, ensuring absolute data privacy and instantaneous updates without any network delay.

Worked Step-by-Step Calculation Example

Worked Example Sandbox

For illustrative purposes, consider the following calculation using our default values. When we initialize the input fields with House Area = 150 sq m, Standard Energy Use = 150 kWh/sqm/yr, Passive House Energy Use = 15 kWh/sqm/yr, Electricity Price = 0.12 $/kWh, the client-side calculator processes the numbers to resolve the formula and produce the final outputs: Standard Annual Energy = 22,500 kWh and Passive Annual Energy = 2,250 kWh and Energy Saved = 20,250 kWh and Cost Saved = 2,430 $ and CO2 Saved = 10,125 kg.

How to Use This Calculator
