Energy Awareness

Visibility into energy costs
Monthly bills contain minimal use information, and are
"rear views" into consumption, as they are received 30-60
days after the energy is used.

The importance of energy visibility
You need accurate, timely, load-specific data to make the best
decision for your organization

The challenge of real estate portfolio management
Maintenance

Energy cost
Multiple geographically dispersed locations
Multiple sites per location
Multiple tenants per site
Multiple appliances per tenant to manage
Capex
This happens every day in your sites
Unscheduled, emergency maintenance
This happens every day in your sites
Heating and A/C on at the same time
This happens every day in your sites
BAS says “lights are off”, really?

BAS systems are not granular enough
I need to take my BMS
down to the device level?
That is expensive!

You need to go down to the device level…
That sounds like a big
hardware investment,
doesn’t it?

…and be able to analyze all that data in real time
I would need to hire a
full time analyst,
wouldn’t I?
Device level monitoring is the game changer
I have to bear the cost of a
BMS at the device level
That sounds like a big
hardware investment
I would need to hire a
full time analyst

Benchmarking to improve efficiency
Your site
Versus your other sites
Versus industry best practice

Best practices
Best Practices
1
Operational
• Monitor and drive user behavior changes
• Prevent equipment performance drift
• Get alert when an asset needs to be maintained or tuned
2
Energy
• Real-time energy waste alerts
• Lower peak demand
• Ensure proper operation of BMS or manual operation
by personnel
3
Maintenance
• Alerts in-advance failure detection
• Monitor technicians’ corrective actions
• Compare efficiency of systems and prioritize
maintenance visits

● Example: Refrigeration system
compressor failure
─ Over consumption alert revealed x3
increase in daily consumption
─ Data drill down revealed non-cycling
compressor
─ Fixed a broken thermostat contactor
─ Saving is $5K/year in energy and $14K in
maintenance
