Why Green?

• was the question
• The better question is . . .

Why Not Green?
It Just Makes Sense

UF Green Growing
City within a City
UF is BIG and consumes significant resources

LEED Cost

• How much does a LEED building cost more than your
  traditional building?
• What standards are associated with your
  traditional building?
• How much more does LEED cost above code? How
  Green is/was your last project?
• What level of certification are you striving for?
• How experienced is your local contractor / design
  community?

30
Current Soft Cost Data

• Estimated soft costs (www.facilitiesnet.com)
• People costs v. Energy or Construction costs

31
Current Cost Data

• Building costs represent less than 10 of the
  cost to own/operate building for life of project
  20 year lifecycle. (www.facilitiesnet.com)

32
Cost Literature Review

• LEED costs
• GSA sites a range of less than 0 for LEED
  certified to a mean of 2.5 addition to total
  budget for LEED silver buildings.
• UF Facilities Planning and Construction claim 0
  additional dollars for a LEED certified building.
• Davis Langdon (architect firm) states design
  firms produce LEED buildings as standard program
  elements (no additional design fee).
• Greg Kats Average Silver rating for schools
  (n33) cost premium 1.84
• Common perception minimum of 10

33
Conclusion on First Costs

• As UF has gained experience with LEED projects
  the associated first costs and process has
  evolved. Major drivers of lowering costs
  include
• Experience of project team members and local
  market
• Evolution of building standards to include LEED
  based language
• Outcome based selection of credits and levels of
  certification

34
UF Annual Saving

• Review of Annual Construction Performance and
  Building Savings
• 10 certified buildings used in summary reports
• Not all buildings achieved credits that are
  summed in the following slides
• Comparisons are based on design estimates. Real
  data forthcoming this year.

Commissioning

44
Why Commission?

• Complex building systems
• Increased energy efficiency
• New technology
• IAQ
• Reduced environmental impact
• ROI
• Reporting and accountability
• Construction Challenges
• Compressed schedules
• Training
• Labor challenges
• Budgets

45
Why Commission?

• Chilled water and steam system
• Renewable source energy
• Heat recovery
• Chiller with heat recovery
• Demand Control Ventilation (CO2)
• MV
• BAS

46
Why Commission? Life-Cycle Perspective
47
LEED-NC Cx

• There are 2 components
• EA Prerequisite 1 Fundamental Building
• System Commissioning
• EA Credit 3 Additional ( Enhanced)
  Commissioning
• District Thermal Energy, Central plant (new since
  May 2008), EAp1 and EAc3

49
Design Review

• Cx performs DD, 60 CD 100 CD reviews
• Format used encourages 2-way dialogue
• Back-check previous comments
• Cx communicate with A/E to review comments and
  confirm understanding of design

50
OM/Submittal Review

• CxA reviews either prior to or concurrent with
  AE review
• All commissioned equipment reviewed
• BAS control drawings reviewed
• Cx provide facility staff with a list of key
  equipment set points

51
Equipment Start up

• CxA works with the contractors and
  sub-contractors
• CxA verify contractors have a quality control
  process
• Cx observes contractors using process
• Interest in process
• Rework, correct, record

52
Training

• Owner, facility staff CxA discuss training
  needs
• CxA communicates needs to construction team
• Contractors adjust training plan to match needs
• CxA followed up with staff after training -
  recommended more training if needed
• AE (CxA) review design intent and basis of
  design

53
Warranty

• Lead by the Owner
• Entire team represented (CxA, AE, GC, MEP,BAS)
  and Maintenance staff
• Discuses warranty issues (open resolved)
• CxA A/E, CM, Owner walk site
• Walk-thru discover unknown warranty and
  maintenance issues

UFs Cx Process

• Best Practice, before LEED
• Procurement, selection process, contract
• Enhanced Commissioning for every project
• Commission through Third party for every project
• Envelope Commissioning

56
Extended Commissioning

• 2 years out, New construction and major
  renovation
• Quarterly in the first year, New Construction and
  major renovation

57
Continuous Commissioning

• Energy Form, Facilities and Physical Plan
  Division
• In the process of forming in-house Commissioning
  team
• Automation of utilities metering
• Chiller plant optimization
