1 Partnership Gwinnett + Southeast Green Series- Debunking Energy Efficiency Myths: Why your bottom line depends on Energy Efficiency Property of VIS VIVA Energy and Service, not to be re-used without permission

2 Trends in HVAC Speaker: Lance Beaton General Manager Property of VIS VIVA Energy and Service, not to be re-used without permission

3 Where to start 1. Integrated Design Approach 2. Preventive Maintenance 3. Commissioning / Retro Commissioning 4. Duct System Sealing 5. Controls and Automation 6. Replacement / Upgrade Trends a. FEMP Priority List b. Commercial Systems c. Geothermal Heat Pumps d. VRF Systems e. Boiler f. Chiller 8. Q & A Property of VIS VIVA Energy and Service, not to be re-used without permission 3 Key Points: - Saving energy makes cents - HVAC is the heartbeat of any building - No better time than now Today’s Topics

4 Driving the industry Property of VIS VIVA Energy and Service, not to be re-used without permission

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

6 6 2.Preventive Maintenance Typical Savings - 10% to 15% Advances... - Building Automation Systems - Real-time - Early warning and detection - Controls integration - Computerized Maintenance Management Systems (CMMS) 60% of all commercial equipment is broken or malfunctioning

7 7 3. Commissioning / Retro Potential Savings - $4 saved for every $1 spent 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

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

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

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

11 11 6b. Commercial Systems Typical Savings - 30% to 40% vs Replacement - ROI 3 to 10 years - If financed, can be 0 years (debt service to energy savings) 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 *17.5 SEER Property of VIS VIVA Energy and Service, not to be re-used without permission

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

13 13 6d. Variable Refrigerant Flow (VRF) - Property of VIS VIVA Energy and Service, not to be re-used without permission 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

14 14 6e. Boilers Property of VIS VIVA Energy and Service, not to be re-used without permission Condensing Boilers Typical Savings - Reduce Natural Gas Heating by 12% to13% 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

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