RapidRate^TM Whole of Home Calculator is an online tool that quickly assesses the energy efficiency of a dwelling’s thermal shell (star rating), and also estimates energy consumption, energy generation, and carbon emissions using a relatively small number of inputs. The RapidRate^TM Whole of Home Calculator inputs and outputs are described in the RapidRate^TM Whole of Home Calculator User Guide. Whilst RapidRate^TM Whole of Home attempts to align with the Nationwide House Energy Rating Scheme (NatHERS), RapidRate^TM Whole of Home is not an official NatHERS accredited tool. Outputs cannot be directly compared as underlying assumptions and calculations are not identical.

Disclaimer

The RapidRate^TM software used to calculate the star rating and outputs is not accredited software under the Nationwide House Energy Rating Scheme (NatHERS) and any star rating or other outputs generated represents an estimated NatHERS star rating and is not a replacement for a NatHERS Certificate.

While the software has been created with due care, the information used to train the software will continue to develop over time, and there is no warranty or representation that the star rating or other outputs are free from errors or omissions or generated with appropriate or accurate assumptions.

The star rating and other outputs are estimated based on certain inputs and assumptions, and no claim is made as to the accuracy, completeness, reliability, currency, suitability or otherwise of the star rating or other outputs, especially where input data is based on assumptions.

The star rating and other outputs are provided on the basis that the end user receiving the star rating and other outputs are responsible for assessing whether it will meet their requirements and be fit or suitable for that person’s or organisation’s purpose or intended use.
