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
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

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
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

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
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
