BREEAM on the International Stage

David Clark Partner – Cundall www.cundall.com

Discussion • Rating tools internationally v International rating tools • BREEAM & LEED differences • How do they compare – case studies • So which one is best?

International Rating Tools • Tools that can be used anywhere in the world: • LEED – Has been used in many countries worldwide – 10 projects registered in UK (1 certified)

• BREEAM International – Versions developed for Europe & Gulf – Bespoke versions can be tailored to suit

BREEAM

LEED

How to choose? • Availability of information – Compliance manuals for both are free pdf downloads

• Suitability to region – BREEAM International must be adapted to suit each region (already completed for Europe and Gulf) – LEED requires little adaptation (more generic) and is used “straight out of the box” – Which approach is better?

• Certification fee to BRE / USGBC – BREEAM fee for 10,000m2 bldg = €1,300 – LEED fee for 10,000m2 bldg = €3,800 – But biggest cost is compiling documentation

6/3/2009

How to choose? • Documentation requirements – Assume both are similar (ie lots required) – LEED all done via website

• Certification process – BREEAM requires Accredited Assessor to prepare rating submission with check and sign-off by BRE – LEED rating submitted on-line by any professional with independent review and sign-off by Green Building Certification Institute (on behalf of US-GBC)

• Rating tool credibility – Both are internationally recognised – Which sets the highest standard (degree of difficulty)?

Comparison of rating tools • Comparisons can be misleading – open to interpretation – tools assess things differently – depends on your point of view

• Case Studies using Australian buildings to compare BREEAM and LEED – Green Star rating tool was adapted from both LEED and BREEAM tools – Buildings were designed without a bias towards either LEED or BREEAM credits

VS1, Adelaide (New Building) • Excellent = Platinum = 6 star • Why LEED was harder on this project – Difficult to get material credits – Specific points for renewable/green power (BREEAM looks at CO2 overall)

55 St Andrews Place (Refurbishment)

55 St Andrews Place (Refurbishment) • Refurbished building in Melbourne CBD • 6,000m2 – net lettable area • BSJ Sustainable Refurbishment of the Year 2007 • Awaiting 4 star Green Star certification • Focussed on good design not points scoring! – – – –

55 St Andrews Place (Refurbishment) • Very Good = Gold = 5 star • 4 Star Green Star tbc • BREEAM rewards improving existing building stock more than Green Star & LEED • BREEAM gives more points for energy improvement

Cundall Sydney Office (fitout)

6/3/2009

Cundall Sydney Office (fitout) • 400m2 fitout in conventional office building • First LEED Platinum rating in southern hemisphere

Fitout ratings • BREEAM

Green Star

– Modified version of building rating

• LEED

25% to 50%

40%

– Separate tool (but similar to New Construction)

• Green Star – Totally different credits. Very specific to tenancy issues

Cundall Sydney Office (fitout) • TOTALLY DIFFERENT APPROACHES! • Green Star has 141 credits, LEED has 44 • Green Star & BREEAM focussed on major tenancies with formal contracts (doesn’t suit small do-it-yourself fitouts) • BREEAM does not address fitout design issues (>80% of points relate to landlord’s building) • Radically different approach to fitout furniture – Green Star looks at each type of furniture – LEED lumps all together – BREEAM doesn’t really assess (< 3% of rating)

Cundall Sydney Office (Fitout) • Green Star – too thorough and too much paperwork = expensive. Sets a very high bar. • BREEAM – really just a base building rating and not relevant to fitouts. Low score reflects poor base building not the fitout design / initiatives • LEED – probably not rigorous enough • CAN’T REALLY COMPARE THE RATINGS!

13

6/3/2009

Summary • New Construction & Refurb ratings – BREEAM, LEED & Green Star are comparable – Excellent = Platinum = 6 star, etc – The choice of tool influences what design and construction initiatives you will target – BREEAM uses local energy regs, LEED uses ASHRAE

• Fitout ratings – No comparison between tools – BREEAM is not practical tool for fitouts

• So, BREEAM or LEED for international buildings?

Which tool is best?
