Under this method, energy savings can be calculated using an engineering assessment that typically includes measured data and industry recognised calculations. This method is commonly used where energy savings are small compared to the overall site consumption, or data for a site’s past energy consumption is unavailable.
This method can be used for residential, commercial or industrial sites and allows you to forward create certificates for 5 years with a discount, or to claim the energy savings on an annual basis.
The Project Impact Assessment Method is now closed to new applicants. However, new applicants are instead able to apply under the Project Impact Assessment with Measurement and Verification Method.
