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?
Current Soft Cost Data • Estimated soft costs (www.facilitiesnet.com) • People costs v. Energy or Construction costs
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)
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 (n=33) cost premium = 1.84% • Common perception minimum of 10%
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
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. UF Annual Saving
Total Waste Diversion for Completed Projects Achieving Waste Diversion Credits
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
Why Commission? • Chilled water and steam system • Renewable source energy • Heat recovery • Chiller with heat recovery • Demand Control Ventilation (CO2) • M&V • BAS
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
Prerequisite Cx EA3 – Additional Cx Vs. OPR / BOD SD / DD Design Construction Documents Submittals Equipment Arrival Start Up BAS Controls Construction & Acceptance TAB Performance Verification O&M Training Systems Manual Post Occupancy In-Warranty Review
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
O&M/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
