WHY GREEN BUILDING RATING SYSTEMS ?
To define “green” and “sustainable” buildings by providing a rating
system by which the design for energy and environmental criteria can
be measured.
Establish a benchmark which buildings can be measured against

RISK ASSESSMENT
Develop a Green Building Risk Profile
• Identify perceived risks
• Are the risks tied to the performance of other trades, consultants,
Owner?
• Rank the risks and liability
• Develop risk management tools and strategies for each risk
WHO IS RESPONSIBLE
Define which party is responsible for administrating the LEED
certification process. Define your responsibilities and level of
participation in achieving the points.
ARCHITECT
ENGINEER
LEED CHAMPION
INDEPENDENT LEED CONSULTANT

INSURANCE AND BONDS
• Currently no surety in Canada is issuing contractor
bonds specific to LEED® Certification
• It is anticipated that by 2012 bonds based on green
building project certification may be required
• The traditional performance bond will not work for
bonding project certification. That will require a
“compliance” bond which may be very new to
contractors and more difficult to obtain
• “Green Contractor’s Insurance” is currently only available
for Pollution and Environmental liabilities
INSURANCE COVERAGE
Confirm that there is adequate insurance coverage,
including professional liability insurance for design
professionals, that takes into account the green nature of
the project
Aquascape Building
St. Charles Building and Code Enforcement
Commissioner Bob Vann said the building is
so uniquely designed only the original
structural engineers have the knowledge to
pinpoint exactly what went wrong. Until
then, no one will be allowed in the building
except to possibly remove some computers
and other necessary work materials..
WARRANTY/GUARANTEE REQUIREMENTS
FOR GREEN PRODUCT

Check warranty and guarantee language
to confirm that new green construction
procedures or installation materials
and/or techniques do not void the
warranty or guarantee for a product

What are the long-term performance
goals and length of warranty issues

Determine if any property
infringements will result from utilizing
new green techniques or equipment and
who is responsible for dealing with any
infringement that may arise

Investigate the availability of green
construction material specified and the
replacement price for such material
PAYMENT RISKS
Address the length of time of inspection and documentation processes
associated with LEED certification in the project construction schedule.
Inspections
Documentation and Submission
Audit and Certification
3-4 weeks in conjunction with Occupancy
4-6 weeks after project completion
18 – 24 months for certification
HOLDBACK TERMS
Commissioning (M&V credit) requirements may result in an additional
holdback period of up to 1 year after substantial completion of the work
If certification of the project is made contractual, final holdback may be
extended by up to 2 years
“As a condition of Substantial Performance the
Corporation will holdback from the applicable progress
payment $100,000 dollars from the Contractor until LEED
Certification has been achieved”
JOURNAL OF COMMERCE
Contractors turning away from LEED
JEAN SORENSEN
correspondent
The construction industry in B.C. and the U.S. is starting to reject the LEED
certification process citing it as too costly and taking too long with too many
uncertainties.
“You can wait up to two years to get certified, the backlog is extraordinary,” said
Helen Goodland, principal of Brantwood Consulting, a green building consultant.
The firm is heading a stakeholders group seeking to find alternatives to achieving
energy efficient buildings and reducing B.C.’s greenhouse gas emissions by 33 per
cent by 2020.
“The industry is quite reasonably rejecting LEED,” she said.
Goodland cited figures for Vancouver, where only 13 per cent of the structures built
to a LEED standard are currently certified.

LEED to CALGREEN
If all the LEED buildings in the US registered today (35,000)
were net zero it would only equate to 1% reduction in total
energy use of all the existing buildings in the US
LEED buildings themselves are not going to impact the industry
as much as code will
We need to be raising the bar with LEED as well as bringing it
up from behind with building code
