GETTING TO GREEN and OUT AGAIN Susan Hildebrand, GSC,LEED AP Director of Sustainability Scott Construction Group
TOPICS FOR DISCUSSION LEED Credits and Contractor Responsibility Defining the role of the Contractor Implementing LEED requirements on the construction site Challenges, obstacles, issues for contractors Cost of implementation
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

CONTRACTOR’S CHECKLIST RISK ASSESSMENT DEFINING ROLES AND RESPONSIBILITIES OF PROJECT TEAM WHAT ARE THE CONTRACT TERMS DEFINE INSURANCE COVERAGES WARRANTY & GUARANTEE RISKS SCHEDULE AND PAYMENT RISKS HOLDBACK TERMS
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 CONTRACTOR
CONTRACT DOCUMENTS Define responsibility if the project fails to achieve LEED certification and what sort of damages flow from such a failure. Review the language of all the contract documents CONTRACT SUPPLEMENTARY GC’S SPECIFICATIONS TENDER DOCUMENTS ADDENDA Keep in mind it is a 3 rd party verifier that has not been involved in the project at all.
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 3-4 weeks in conjunction with Occupancy Documentation and Submission4-6 weeks after project completion Audit and Certification 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 “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 Malcolm Lewis CTG Energetics california-green-building-code/
