2TOPICS FOR DISCUSSION LEED Credits and Contractor Responsibility Defining the role of the ContractorImplementing LEED requirements on the construction siteChallenges, obstacles, issues for contractorsCost of implementation
3WHY 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 againstThere is no real true definition of a green buildingGreen Washing – “ False or exaggerated claims of performance” But do they?

9LEED 2009 SUSTAINABLE SITES Pre-Requisite 1 Construction Activity Pollution PreventionREQUIREMENTSBULLETIN EV Effective May 1, 2002, an Erosion and Sediment Control Plan is required for all construction activities where the soil is disturbed and sediment or construction related wastes may be discharged into the City Sewer system. The Erosion and Sediment Control Plan must be submitted as a part of the building permit application.CAPP and Erosion and Sedimentation Control (ESC) measures are the activities, practices, devices or combinations thereof put in place to control soil erosion, waterway sedimentation, and airborne dust generationCONTRACTOR RESPONSIBILITYDevelop a site plan indicating areas of use for site activities showing limits of excavation/laydown areas. Use existing paved areas where possible for storage/stagingLimit greenfield site disturbance as per LEED requirements.Work within limitations provided during excavation and site activitiesPhoto Documentation of site limits and activities within

18CONTRACTOR’S CHECKLIST RISK ASSESSMENTDEFINING ROLES AND RESPONSIBILITIES OF PROJECT TEAMWHAT ARE THE CONTRACT TERMSDEFINE INSURANCE COVERAGESWARRANTY & GUARANTEE RISKSSCHEDULE AND PAYMENT RISKSHOLDBACK TERMSBefore we even get into the ground
19RISK ASSESSMENT Develop a Green Building Risk Profile Identify perceived risksAre the risks tied to the performance of other trades, consultants, Owner?Rank the risks and liabilityDevelop risk management tools and strategies for each risk
20WHO IS RESPONSIBLE ARCHITECT ENGINEER LEED CHAMPION Define which party is responsible for administrating the LEED certification process. Define your responsibilities and level of participation in achieving the points.ARCHITECTENGINEERLEED CHAMPIONINDEPENDENT LEED CONSULTANTCONTRACTORThere are a number of issues that parties participating in a green building project need to address. Parties that emphasize open communication, clearly define performance expectations, fully examine the risks of a green project, and deal with these issues in their contract are likely to have greater success in avoiding costly dispute resolution or litigation than those who choose to ignore them
21CONTRACT DOCUMENTSDefine 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 documentsCONTRACTSUPPLEMENTARY GC’SSPECIFICATIONSTENDER DOCUMENTSADDENDAKeep in mind it is a 3rd party verifier that has not been involved in the project at all.Review all the documents with a fine tooth comb. The Consultants typically remove any responsibility for achieving certification from their contracts defaulting it to the Contractor. Financial obligations are typically attached to obtaining certification…….read carefully
22INSURANCE AND BONDSCurrently no surety in Canada is issuing contractor bonds specific to LEED® CertificationIt is anticipated that by 2012 bonds based on green building project certification may be requiredThe 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
23INSURANCE COVERAGEConfirm that there is adequate insurance coverage, including professional liability insurance for design professionals, that takes into account the green nature of the projectAquascape BuildingSt. 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..
24WARRANTY/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 productWhat are the long-term performance goals and length of warranty issuesDetermine if any property infringements will result from utilizing new green techniques or equipment and who is responsible for dealing with any infringement that may ariseInvestigate the availability of green construction material specified and the replacement price for such materialMaking sure there are no extended guarantees for product or technology that has not been tested because it is new
25PAYMENT RISKSAddress the length of time of inspection and documentation processes associated with LEED certification in the project construction schedule.Inspections weeks in conjunction with OccupancyDocumentation and Submission 4-6 weeks after project completionAudit and Certification 18 – 24 months for certificationDefine/review any line items in the Schedule of Values for Credits or Documentation requirements that will delay progress payments
26HOLDBACK TERMSCommissioning (M&V credit) requirements may result in an additional holdback period of up to 1 year after substantial completion of the workIf 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”Can anyone tell me if the consultants or leed coordinator have this is their contract?
27JOURNAL OF COMMERCE Contractors turning away from LEED JEAN SORENSENcorrespondentThe 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.
28LEED to CALGREENIf 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 USLEED buildings themselves are not going to impact the industry as much as code willWe need to be raising the bar with LEED as well as bringing it up from behind with building codeMalcolm Lewis CTG Energetics
