  1. Garden Spot VillageChiller Plant Re-ConfigurationJune 25, 2008

  2. Trane - Pennsylvania District Overview • 180 Dedicated Employees in Pennsylvania • Commitment to Support and Sustainability throughout the Useful Life of Systems • 62 Total Service Trucks • 18 BAS Technicians • 9 Full Time Project Managers • Over 30 Degreed Engineers • Local experience designing and operating high performance systems Committed to High Performance Buildings for Life

  3. Pennsylvania Team Engineering Design and Operation Experience Pittsburgh Convention Center (6,000 Tons) • Variable Primary Flow Design • Optimized plant design through design collaboration • Trane Central Plant Control (10-Yr Full Plant Maintenance Contract) Point Park University (1,000 Tons) • Sustainable / LEED Building Design • Optimized plant design through design collaboration • Integral free cooling • Trane Central Plant Control Brethren Home - Harmony Ridge (Existing Chiller Plant) • Primary-secondary flow design with tertiary system pumps • Trane Central Plant Control Daniel Boone School District • Variable primary flow design with dissimilar air cooled chillers • Primary-secondary hot water system • Trane Central Plant & Hot Water Plant Control • Energy savings guaranteed by Trane

  4. The Garden Spot Village System

  5. ΔP Chillers 55°F 450 GPM ~ ~ 45°F VFD VFD 150-600 GPM

  6. ΔP Chillers ~ ~ 3-Way Valves ~ ~ Increased GPM Lower Temp Mix adds Temp VFD Mix adds Temp VFD

  7. Chillers ~ ~ 3-Way Valves ~ ~ Increased GPM Lower Temp ΔP Mix adds Temp VFD Mix adds Temp VFD • Operational Result: • Higher volumes • Lower return temperatures • Higher supply temps • Consequences: • Use of more secondary pump horsepower (higher energy expense) • Secondary volume initiates second chiller start unnecessarily (energy and equipment wear) • Low return temps have chillers run at low load • High supply temps increase space humidity • Unstable system dynamics

  8. ΔP Chillers ~ ~ New Valves ~ ~ Controlled Bypass Flow-meters 250-800 GPM Chiller flows VFD 250-1000 GPM The Variable Primary system design allows all of the water to go through the chillers and allows increased volumes per chiller. The result is an ability to match load and tonnage over a broad range of system flows. VFD New Pumps and VFDs

  9. System Modification Proposal • Turnkey Project • Includes Engineer’s stamp • Includes pumps, drives, piping and control modifications that would have to be covered under the Village Square project • Improves humidity control • Saves energy • Stabilizes system • Protects equipment investment
