How do we calculate the energy savings in Yearly kWh?
We start by calculating your energy consumption in relation to your current windows and selected region. Using this equation:

(U-Value of current windows x Glass area of home) x Entire year's recorded degree days for selected region x (24/1000) = Current energy consumption

We calculate your energy consumption in relation to the selected CWG windows and selected region. Using this equation:

(U-Value of new CWG windows x Glass area of home) x Entire year's recorded degree days for selected region x (24/1000) = New energy consumption

To get the total savings, we calculate the difference between the new energy consumption and the old energy consumption, Using the following equation:

Current energy consumption - New energy consumption = Total energy savings*

*Please note, we are only calculating the difference in energy consumption between your current windows and CWG windows, the energy efficiency of your entire home is not required.

*How do we calculate the yearly CO2 Savings?
Because we know the energy savings, we can multiply the energy savings by the amount of C02 created per kWh. Using this equation:

Total energy savings x CO2 generated per kWh = Total CO2 savings

**How do we calculate Savings?

Financial Savings are calculated by multiplying the kWk Savings by £0.34 per kWh, as published by the Energy Price Guarantee From 1 October 2022.
