Identify existing lighting that is being replaced with a one for one replacement. If NC skip this step.

Find a DLC or Energy Star qualified fixture and use the prescriptive form to determine the incentive for this fixture type.

EE sales person verifies your information and processes your incentive form. Once pre-approved, purchase this lighting within 12 months.

Submit the BOM and cut sheets for each fixture type. An incentive check will be issued to the building owner.

Lighting Designer Incentive

The lighting designer receives a sum that

equals 20% of what ever the total utility lighting

incentives are for this project, up to $20,000

This incentive goes directly to the lighting

design team to fund their design and modeling

efforts to achieve deep lighting energy savings

Incentive will be paid upon confirmation of the

project’s lighting installation and controls

initialization.

33

33

Lighting Designer Incentive

Eligible projects can be interior or exterior projects of any size

and complexity in National Grid MA and RI territories.

Lighting design must exceed IECC 2012 energy code by a

minimum of 15%

Projects must exceed code mandated lighting controls, or

participate in the Network Lighting Controls initiative

Only lighting designers who have obtained an LC, CLEP or new

Certified Lighting Designer CLD certification.

LDI qualified projects are exempt from using the DLC or

EnergyStar qualified products list. The design team must

adhere to the IALD “Guidelines for Specification Integrity”,

detailing that their specs meet and/or exceed DLC technical

requirements.

Lighting manufacturers representatives and lighting distributors

are not eligible for this incentive

34

Lighting Designer Incentive - Initiative

LDI – Process

1. Lighting designer submits application indicating intent to participate

in the LDI program and their qualifications as a professional lighting

designer. They also indicate that they will design the lighting for this

project to meet the LDI criteria.

2. Lighting designer submits authorization form to owner who signs it

directing the LDI incentive to be paid to the lighting designer.

3. Lighting designer designs the most energy efficient, quality lighting

design and controls system that exceeds local energy code. They

work with our energy efficiency sales team to identify project

incentives.

4. Lighting designer submits lighting incentive program applications for

this project to the utility energy efficiency sales person to process.

5. Lighting design is submitted for LDI incentive for project. The

lighting designer receives 80% of the initial payment upon approval.

6. Three months after lighting system is initiated, the lighting designer

submits documentation verifying lighting controls system

performance

7. After project is post inspected verifying lighting system performance

and energy savings. Lighting designer receives final 20% of LDI

incentive payment.

8. Project will have substantial M&V for one year to verify energy

savings, this will include an occupant satisfaction questionnaire.

Summary High Efficiency Lighting Beyond Technology

New IECC 2012 code allows for code based comprehensive solutions with

LED’s and controls for 2016.

Lighting replacement solutions have limited EE savings potential

Comprehensive lighting projects require better trained designers/engineers

and installers. Also, better modeling to redesign spaces to fit occupant

needs.

Adaptive LED fixtures with integral controls increase savings, are easy to

commission and provide occupant comfort

Network Lighting Control systems are the next big EE Lighting energy

savings up to 65% energy savings

Enhanced Performance Lighting can accommodate; interior, exterior and

controls at adjusted incentive levels

Lighting incentives must favor comprehensive lighting projects over fixture

replacement solutions
