Sustainable? Zero CarbonGovernment targets!

• Domestic buildings should be zero carbon by 2016

• Non-domestic buildings should be zero carbon by 2019

• Existing buildings? • New buildings only account for 1%?

Building Research Establishment (BRE 2002) published a guide to assist developers when identifying sustainability issues.

Issues include:

• Land Use, Urban Form and Design

• Transport

• Energy

• Impact of individual buildings

• Natural resources

• Ecology

• Community

• Business

A sustainability checklist for development

BREEAM

Building Research Establishment Environmental Assessment Model

BREEAM provides a numerical weighting system that is applied to new and existing buildings to assess their ‘sustainability’.

www.breeam.org

BREEAM Categories and weightings

• Management 15%• Health and Welfare 15%• Energy 13.6%• Transport 11.4%• Water 5%• Materials 10%• Land use 15%• Pollution 15%

Trained assessors score category

• The BREEAM assessor awards a numerical score to each category and the scores are totalled to give an overall rating.

• The designated BREEAM ratings of pass, good, very good or excellent can be awarded.

Minimum score required to achieve BREEAM rating

• Pass 25• Good 40• Very Good 55• Excellent 70
