Sustainability Presentation
April 2015
Why Green Building Certification?
• Market recognition for low environmental impact buildings, confidence that tried and
tested environmental practice is incorporated in the building, inspiration to find
innovative solutions that minimize the environmental impact
• A benchmark that is higher than regulation
• A system to help reduce running costs, improve working and living environments
• A standard that demonstrates progress towards corporate and organizational
environmental objectives
• Positive association with corporate brand – helps attract and retain the best staff and
enhances corporate image to the wider community
US Green Building Council has four levels of LEED Certification:
• LEED Certified
• LEED Silver
• LEED Gold
• LEED Platinum
LEED Platinum
80+ points
LEED Certified
40- 49 points
LEED Silver
50- 59 points
LEED Gold
60- 79 points

BREEAM Overview
What does BREEAM do?
• Uses a straightforward scoring system that is transparent, flexible,
easy to understand and supported by evidence-based science and
research
• Has a positive influence on the design, construction and
management of buildings, defines and maintains a robust technical
standard with rigorous quality assurance and certification.

How much does Green Building Certification Cost?
Design and construction costs
• Whilst there can be additional costs, the premium is not as
high as perceived by the development industry
• As investors and occupants become more knowledgeable with
the environmental and social impacts of the built environment,
buildings with better sustainability credentials enjoy
increased marketability
• Studies show a pattern of green buildings being able to attract tenants and to
command higher rents and sales prices
• In markets where green is mainstream, there are indications of emerging
‘brown discounts’ where buildings that are not green may rent
or sell for less
• Integrated design process will increasingly play a key in role in keeping costs
down without compromising quality

How much does Sustainability Cost?
Approach
• Experienced Design Teams typically achieve LEED and BREEAM ratings at a
lower cost
• Approach: Target zero/low cost credits first
• Project Manager needs to consider
sustainability approach from an early stage
• Decreasing cost of sustainable materials and
technologies as industry knowledge develops
• Early design decisions on fabric and form can reduce the cost of
achieving a high level of certification
• Minimise need to target high cost credits
• Low cost credits may become more costly if implemented late
