Energy Performance Guarantees Maintaining investment and commitment of entire team after design and construction
MSRP Consortium Research Project University of Minnesota Mortenson Construction Chris Massey Spring 2015
Definition
Energy Performance GuaranteesSimilar to other energy regulatory programs: LEED, Living Building Challenge, Architecture 2030, and state energy codes like Minnesota’s B3 program, Energy Performance Guarantees (EPG) provide a way for owners and clients to have some control in the energy use of their buildings. This control happens early in the design and construction phase as opposed to post occupancy, like energy performance contracts. EPGs take the energy regulations of other programs a step further through financial incentives or penalties.
Function
The energy performance guarantee performs many different roles: -Places responsibility, on design/build firm, for the building to perform as designed -Encourages investment of entire design team to solve problems -Mitigates owners risk -Helps align owner and design team’s goals -Provides accountability and facilitates an ongoing relationship with the construction team for a period of time after construction is completed -Ensures construction team will work with those operating the building -Useful tool in achieving and proving other energy tools like LEED, Living Building, etc.

Washington State University at Everett Campus Center Everett, WA To be completed August 2017 Campus Center Building Owner- Washington State University Contractor-Hoffman Construction Architect- SRG Architects Mech./Elect. Sub- McKinstry Design-Build 95,000 ft2 $50.36 million total Energy Design Criteria *LEED Silver- with specific credits, *water performance requirements, *Specific Targets= 50% reduction in energy cost relative to ASHRAE 90.1 2007 baseline, EUI between 25-40 kBtu/gsf-yr, *Prescriptive Requirements= Wash State Energy Code Financial Incentive of EPG*3 year performance period, *$240,000 financial incentive if DB meets performance requirements Companies Understanding of EPG- passed down from the state legislature that’s funding the job. Energy Performance Guarantee, Maintenance Operation Guarantee. Keeps contractor accountable for environmental control systems. Team organization- Upfront collaboration was key in the selection process. McKinstry was a vital member of the team. SRG’s greatest energy contribution was envelope and lighting. Energy Modeling- a lot more detail and back and forth to make sure fully integrated energy strategies. How to deal with user variable- both guarantees just tied to environmental control systems, M&V Period- 12 months to dial building in and then 3 years on M & V period. Risks in the project and how they were managed- Part of DB’s proposal must include how they plan to manage both EPG and MOG (maintenance and operation guarantee). SRG’s contractual relationship with Hoffman did not include any part of the guarantee. McKinstry felt brand risk much greater than financial risk.
1063 Block Replacement Project Olympia, WA To be completed Summer 2017 Office Building Owner- Washington State Department Contractor- Sellen Construction Architect- ZGF Architects Design-Build 215,000 ft2 $82 million total Energy Design Criteria EUI= 30.1 with renewables, $1.18/ft2 for operations and maintenance, LEED Platinum Financial Penalty of EPG5 year performance assurance through M&V, tier release schedule of compensation, $420,000- (equal to 1st year operating costs) withheld Companies Understanding of EPG- Meeting the design and construction criteria for 5 years, responsibilities are coupled at years 2 and 5. Ripples energy design right through to the thinking at the beginning. Team organization- Team that was picked was integrated and had done EPG projects before. All members part of team have worked together on at least one project- most more than that. Highly integrated, successful team. Use of BIM- Mainstream for every project. How to deal with user variable- These buildings are going to take a retraining of the users as well. If users do not follow assumptions in performance agreement, contractor is off the hook. M&V Period- 1 year to tune it. Quarterly reports through 2-5. Risks in the project and how they were managed- Retraining of facility staff to change old habits/ ways of doing it. Full-time mechanical/electrical engineer on project site for whole first year, in charge of all operations and maintenance as well as training. Distinguishing Factors- 1063 has a 75-year minimum life- before significant changes. Payoffs begin around year 25. This works because in WA public owns all buildings.
Federal Center S 1202 Seattle, WA Completed 2012 Office Building Owner- GSA Contractor-Sellen Construction Architect- ZGF Architects Design-Build 209,000 ft2 $74 million total Energy Design CriteriaLEED Gold, 2030 Challenge compliant, Energy Star Score of 100top 1% energy efficient office buildings in nation, 30% better than ASHRAE 90.1 2007, EUI of 28 or less Financial Penalty of EPG1 year performance period, $400,000 dollars withheld Companies Understanding of EPG- GSA required list of minimum performance criteria in contract, EUI of 28 or less, basis of contract. Team organization- Very important how integrated selected team was. How the teams had worked together to predict how they would work together. Use of BIM- BIM can go further but this project took a good step with it. Energy Sources- Primarily electric with geothermal. Phase change machine can cool the building on almost every day until 2 pm. How to deal with user variable- Educational programs- both email and classes. M&V Period- Adjusted calculations, Monthly meeting with DB firm. â&#x20AC;&#x153;continuous commissioning.â&#x20AC;? Success of the project- Keeping financial penalty made sure the entire team stayed engages- already a great team but money made a difference. DB as invested as GSA to prove building would run as well as designed. Risks in the project and how they were managed- Contractor initially felt there was a greater risk but difference was made when contractors understood what GSA was after. Main lawyer never came into the mix- everyone was on board as a team.
King County Children and Family Justice Center King County, WA To be completed September 2019 Justice Center Owner- King County Contractor-Howard S. Wright Architect- HOK Architects, Integrus Architects Design-Build 347,000 ft2 $210 million total Energy Design Criteria LEED Gold, King County Green Building Ordinance, state LCCA requirements, King County City’s Collaboration Requirement, DOE Better Buildings Challenge, Seattle’s 2030 district commitment, 20% better than Seattle Energy Code Financial Incentive of EPG$500,000- (equal to 1st year operating costs) withheld during 3 year performance guarantee period, one time payout
Companies Understanding of EPG- Primary motivation was to ensure the building performs as designed. Provides accountability and facilitates an ongoing relationship with the construction team for a period of time after construction is completed. Secondary goal is to ensure the building aligns with county policy and target. Team organization- IPD, ensure strong pre-construction planning- improved cost control- quality and budget management. Use of BIM- Yes BIM- some specific requirements for how the building needs to be modeled but also work with design team. Energy Sources- Consider both site and source EUI, performance guarantee just site. How to deal with user variable- Work with design team to minimize plug loads going into the building- Update the model to reflect real conditions as construction progresses. Risks in the project and how they were managed- Risk on owner of having the building actually perform as designed- point of guarantee to keep designers on board making sure it actually works and trains facility operators. One time payout, started with incremental system but owner felt didn’t give enough control.
Research Support Facility Golden, CO Completed Fall 2011 Research Building Owner- National Renewable Energy Laboratory Contractor-Haselden Construction Architect- RNL Architects Design-Build 222,000 ft2 $80 million total Energy Design Criteria35.1 kBtu/sf-yr(including data center), 50% better than ASHRAE 90.1 2004, 3 tiers performance objectives: mission critical/highly desirable/if possible Financial Incentive of EPGInitially- 100% project price at risk, Actually- 50% project price at risk Companies Understanding of EPG- Owner develops performance specifications and the design-builder comes up with the solutions. Team organization- Integrated design and construction with significant upfront planning. Owner devoted a team, IPT, to meeting regularly with the DB team to make sure the building was an integrated system. Energy Modeling- Modeling early and often, Having a computer model of the proposed RSF ensured that performance expectations were being met as the design evolved and construction continued. Energy Sources-Thermal massing, triple glazed operable windows, hydronic heated/cooled through thermal slabs in ceiling. Solar panels and an energy efficient data center. How to deal with user variable- “You can design and build a very efficient building, but what you need are all of the occupants in the building to make that same commitment.” Wendy Weiskopf, Interiors Manager, RNL What made it a success of the project- Educating the Team. Clear, Comprehensive RFP. Prioritized Scope. Award Fee- Money drives behavior, and DOE/NREL was willing to pay for superior performance. Risks in the project and how they were managed- Once the design-builder has assumed contractual responsibility for achieving the performance goals, the owner’s risk is dramatically reduced compared with a design-bid-build scenario.
