Greater Cambridge Local Plan Preferred Options

Representation ID: 58501

Received: 13/12/2021

Respondent: University of Cambridge

Representation Summary:

Achieving all five BREEAM WAT01 water conservation credits is an extremely challenging standard that is likely to go beyond the limits of viability for smaller projects, projects with limited roof collection area, and projects with functions that do not fit the BREEAM standardised calculation methodology. There is a risk of ‘white elephant’ grey water recycling and rainwater harvesting systems that are too small to be sustainable in terms of maintenance and operating cost and ask that guidance on the appropriate threshold of viability be provided; ideally in the form of worked examples for typical building types (office, education, industrial).
