    The Green Guide Calculator

    Online Bespoke Specification Tool for BREEAM Assessors

    BRE Global have created the Green Guide Calculator to enable BREEAM and CSH assessors to quickly and efficiently generate Green Guide ratings for a significant proportion of specifications not listed in the Green Guide Online.

    The Green Guide Calculator database is based on the components currently used to create specifications within the Green Guide Online. These components can be selected and combined to generate instant Green Guide ratings for a multitude of different specifications. Periodically BRE Global will add new components to the database, as and when they become available. If a required component is not present, assessors should submit their model as a Bespoke Green Guide Query from within the tool. BRE Global will calculate the rating and confirm the result to the assessor.

    We trust you will find the Green Guide Calculator a useful and time saving tool.

    Please note that the Green Guide Calculator is not yet available for public use.  This version is subject to change.

    To access the Green Guide Calculator, you must be a licensed BREEAM/EcoHomes/Code for Sustainable Homes Assessor.  Use your BREEAM Extranet login details to continue.

The value given is directly related to the data entered by the user. It is therefore very important that the user enters the correct data. BRE Global is not responsible for incorrect results due to input error nor can BRE Global guarantee that the values when submitted in the BREEAM/CSH/ Ecohomes assessment report will result in a particular rating as these are subject to a separate quality assurance process.
