6. How to Speak BAS

7. Open Protocol
 1995: ASHRAE Standard 135
 2000: founding of what’s now
 Many vendors capable

8. Data: Equipment

10. Seamless interface

11. Next step: Web apps

12.  Weather
 Demand Response, real-time pricing
 Enterprise systems

17. “Analytics”
 Technical audience
 Proactive vs. reactive
 Finding patterns in data
Drives: technical decisions

19. Predictive Analytics
 Trends
 Weather forecasts
 Alarm prioritization
 Energy benchmarks

Failure!

23. “Dashboards”
 Financial/managerial audience
 Purely reactive
 Finding areas for investment
Drives: business decisions

24. Dashboards in use

26. “Kiosks”
 Non-technical audience
 Marketing/educational tool
 Interactive = fun!
Drives: behavioral decisions

27. Tenant energy use
 Direct & indirect impact
 60-80 % total energy = tenants*
 Partnership
*Source: ENERGY STAR

28. Behavioral impact
 Change habits
 Reduce consumption
 Lower costs

36. Beyond the Kiosk
 Kiosk alone – ineffective
 Behavior change is hard!
 Add programs
 Consumption competitions
 Data challenges
 Sustainability campaign

38. Analytics Example: Water Loss
In two months, tower overflow resulted in $80,000 loss.
Challenge:
Make your metered data work for you.
Solution:

39. Analytics Example: Water Loss

40. Dashboard Example: Plant Efficiency
How do you select the best design for your campus?
Challenge:
Try them all, build a dashboard.
Solution:

41. Dashboard Example: VSD Chillers
Should you retrofit existing chillers with new VSDs?
Challenge:
Yes. Prove it by monitoring, trending, plotting kW & load.
