Customer Attitude Study Results:

• Residential Interest: highest among condo/coop owners (49%) and 1-4 family homes (35%)
• Commercial Interest: 38% of commercial customers have high level of interest

• Factors driving interest:
– Want to help the environment (32%)
– Want to lower future bills (20%)
– Want rebates/incentives (26%)

• Customer Expectations:
– Participate in simple programs
– Knowledge of cost savings, rebates, and payback
– Individualized support from project start to finish

Multi-family Energy Efficiency Program

Overview:

– Building and units receive an energy survey showing eligible

energy conservation measures and savings.

– Owner receives financial incentives for upgrading to energy efficient

efficient equipment that is cost effective.

– Participating building’s residents receive free installs

(including CFLs, smart strip, showerhead, and faucet aerator).

• Eligible Customers:

– Owners or managers of multi-family buildings with 5-75 units (including

rent-controlled, rent-stabilized, market-rate rentals, co-ops, and condos).

– Must be a Con Edison customer for either firm gas or electric

• Contractor:

– The Association for Energy Affordability (AEA)

minimum system requirements: 9

1. Must satisfy total resource cost calculation.
2. Remote access and monitoring capabilities via web
3. Apartment sensors in 25% of units (no less than 5)
4. Outdoor reset capability
5. Feedback sensors:

Stack temperature sensor
DHW temperature sensor
Outdoor temperature sensor
Supply or return water temperature sensor (for Hot Water systems)
Condensate return temperature sensor (for Steam systems)

6. Perform boiler staging for multiple boiler systems.

Program Statistics on EMS

• 11 systems installed
• 44 systems under contract
• $125,000 in incentives
• 10%-15% realized energy savings

Market Barriers

• Technophobia
• Strict Cost Effectiveness Standards

14

Behavioral Impact on EMS

• Education of building manager
• Commitment to using the system and responding properly

to alerts

• How often does the super bypass the system?

• A monitoring contract may be needed!

Research Needs

• Increasing the cost effectiveness of EMS

- adding lighting control, motor control
- raise energy befits with minimal cost increase

• Study building’s commitment to using EMS

- quantify the added benefit of using professional
monitoring service.
