7 Genzyme Sustainability Programs Energy Program Results Saved 3130 MTCO2 fromSaved 6072 MTCO2 from 2009 to present due to sustainable commissioning practices and Implementation of 79 energy conservation projectsAchieved with the program last year a 278% internal rate of return with a 3 ½ month payback on investment resulting in a 5 yr NPV of $9.1M on a 1.4m investmentNew mission statement
8 Genzyme Sustainability Programs How did we do it? Formed a focused team in 2007 (Supply, Demand, GHG)Conducted ASHRAE level 1 energy audits all major energy consuming sitesObtained 1.9m in financing to implement ECM’s with a 1 year or less return on investmentAggressively pursued and completed 79 energy projectsCombined energy auditing, modeling, retroactive and ongoing commissioning into one service
9 Genzyme Sustainability Programs How did we do it? Allocated funding to sites for ECM engineering, controls, reprogramming, and addressing functional issuesHeld weekly teleconferences with our sites to review progress, schedule, budget, and M&V of ECM’sMeasured savings through actual energy usage, conservative engineering calculations, and meteringAggressively pursued utility rebates
10 Genzyme Sustainability Programs International common theme ECM’s Lighting levels too highLack of lighting sensorsSequence of operations not optimized for energyAir change rates beyond EU classification requirementsHumidity and temperature control parameters (not required)Unnecessary HVAC in mechanical spacesBroken/out of calibration controlsFree cooling not being utilizedStrategic Demand ControlThermostatic dead band ranges too narrowSimultaneous heating and coolingHigh purity water and steam usages (steam trap failure)Lacking use of grey waterMechanical equipment upgradesLess than ideal boiler efficienciesHigh air filtration requirements
11 Sustainable Commissioning Concept Combining energy auditing, RCx, OCx Annual energy auditing(conduct operational interviews, functional testing, energy modeling)Continuous commissioning SM (OCx)(artificial intelligence is used to collect fault data)Retroactive commissioning (RCx)(collect generate fault data from observations)
12 Sustainable Commissioning Concept Annual functional and operational auditing The energy assessment team consists of 4 board certified energy professionals trained in energy auditing and energy management with a focus on retroactive commissioning.Energy Audit Director:Steven Driver, Ph.D, CEA, CEMCertified Energy Auditor, Certified Energy ManagerMulti-Discipline Energy Auditor:Jennifer Jones, CEACertified Energy AuditorMechanical Energy Auditor:Jeffery Fong CEA, CEMElectrical Energy Auditor:Tim Rossini CEA, CEM, LEED AP
13 Sustainable Commissioning Concept Annual functional and operational auditing Obtain utility bills, square footage, usage, hours, location, staff to assist in audit, contact info, develop scheduleKick off meeting, walk-through, functional testing (RCx), operational interviews, exit presentationSurvey, measure, input building into Equest and validate to energy billsCreate final report, estimate costs for ECM’s, savings, and ROI, IRR, NPV – use energy modelPresent finding to site management in form of ppt presentationReturn to site to rank ECMS (ROI, quick, simple, feasibleAdd high priority ECM’s to international tracking matrix, conduct weekly meetingsReturn to site for re-assessment (functional test annually RCx). Implement OCx whenever feasible.
15 Sustainable Commissioning Concept Functional and operational auditing Build an energy model and calibrate to existing energy bills to analyze demand and understand where energy is being consumed. Identified ECM’s are profiled and parametric runs completed using different alternatives to understand financial impact on energy
16 Sustainable Commissioning Concept Combining energy auditing, RCx, OCx
17 Sustainable Commissioning Concept Combining energy auditing, RCx, OCx The process must become sustainable(Annual Energy Auditing) + (Retroactive Commissioning) +(Ongoing Monitoring) + (Energy Modeling)When is it time for a tune up?
18 Sustainable Commissioning Concept Combining energy auditing, RCx, OCx In 2007 there were still many unanswered questions around commissioning:In a recent study of 60 commercial buildings conducted by the Oregon Office of Energy, half suffered from control problems such as malfunctioning equipment.According to Torcellini and Pless (2006), the most frequently cited barrier to widespread use of building commissioning is the decision-makers' uncertainty about its cost-effectiveness.Gordon (2007) claimed that using computer technology for energy monitoring allows maintenance workers to be called only when something requires repair.Lee et al. (2007) claimed in a recent study of 60 commercial buildings that over 50% had control problems, 40% had problems with HVAC equipment, and 33% had sensors that were not operating correctly.
19 Sustainable Commissioning Concept Two year study of RCx and Ongoing Monitoring A study was needed to understand the benefits of commissioning.From fault detection rates were analyzed in 80 buildings across the US (40 Ocx, 40 Rcx) 100k s.f. in size, mixed use (lab, office, retail, university).The result was a 58% increase in fault detection for ongoing monitoring and 26% increase for RCx if the two technologies are combined.

21 Sustainable Commissioning Concept Energy savings from ongoing and retroactive commissioning
22 Sustainable Commissioning Concept Combining ongoing monitoring and RCx concurrently (Case Study 1) In 2011, RCx and RCx were employed concurrently in a LEED rated gold building approximately 6 years old.
