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
