  5. 1. Integrated Design It all starts here.... - 30% to 50% vs. Historical - Enhanced Productivity - Less Maintenance - ASHRAE Guidelines 5 (c)StartYourDoc.com Property of VIS VIVA Energy and Service, not to be re-used without permission

  6. 2.Preventive Maintenance 60% of all commercial equipment is broken or malfunctioning Advances... - Building Automation Systems - Real-time - Early warning and detection - Controls integration - Computerized Maintenance Management Systems (CMMS) Typical Savings - 10% to 15% 6 Property of VIS VIVA Energy and Service, not to be re-used without permission

  7. 3. Commissioning / Retro Key Steps - Hire really smart, practical people - Start with end in mind - Set Budget - Build Team - Assign Roles and Responsibilities - Execute - Train and Educate - Measure and Verify - Rinse and Repeat Potential Savings - $4 saved for every $1 spent 7

  8. 4. Duct sealing Key Steps to Remember - Test - Check for dangers - Seal - Re-test Typical Savings - 5% to 35% (highly situational) - ROI of 2 to 5 Years 8 Property of VIS VIVA Energy and Service, not to be re-used without permission

  9. 5. Controls and Automation Look for... - Open architecture - Cloud based - Wireless - Load balancing - “Coopetition” - Occupancy sensors Typical Savings - 15% to 35% (situational) - ROI of 2 to 10 Years 9 Property of VIS VIVA Energy and Service, not to be re-used without permission

  10. 6a. FEMP Priority List Top Federal Energy Priorities #1 Lighting technologies #2 HVAC 10 Property of VIS VIVA Energy and Service, not to be re-used without permission

  11. 6b. Commercial Systems Advancements.... - Efficiency Ratings - Economizers (free air) - Integrated ERV’s - ECM Motors - Electronic Expansion Valves - Hybrid integration (HP / Gas / Water) - Variable Speed Compressors - DOE Rooftop Challenge *19.5 IERR Typical Savings - 30% to 40% vs Replacement - ROI 3 to 10 years - If financed, can be 0 years (debt service to energy savings) *17.5 SEER 11 Property of VIS VIVA Energy and Service, not to be re-used without permission

  12. 6c. Geothermal Heat Pumps Trending.... - State of Maryland first to recognize Geothermal for Renewable Energy Credits - Tax Credits - Need a site analysis Typical Savings - 30 to 40% vs. Standard Systems 12 Property of VIS VIVA Energy and Service, not to be re-used without permission

  13. 6d. Variable Refrigerant Flow (VRF) - CITY MULTI vs. VAV CITY MULTI vs. WSHP CITY MULTI vs. 4-Pipe • 2 - PIPE SYSTEM, SIMULTANEOUS HEATING AND COOLING, OPERATES AS A HEAT-PUMP, UP TO 150% CONNECTED CAPACITY, ZONING SYSTEM, VARIABLE CAPACITY INDOOR UNITS, INTEGRAL CONTROL SYSTEMS 13 Property of VIS VIVA Energy and Service, not to be re-used without permission

  14. 6e. Boilers Condensing Boilers Features.... - Uses flue gas as a way to take flue gases from heat exchanger to achieve higher efficiency - Improves combustion efficiency ~10% - Same technology as used in water heaters Typical Savings - Reduce Natural Gas Heating by 12% to13% 14 Property of VIS VIVA Energy and Service, not to be re-used without permission

  15. 6f. Chiller Features.... - Water Cooled - Oil-Free - Variable Speed (excellent partial load) - Magnetic Bearing - Modularity Centrifugal Chiller US NAVY Retrofit- 240 Ton Typical Savings - 40 to 50% Cooling Savings vs. Replacement 15 Property of VIS VIVA Energy and Service, not to be re-used without permission
