Baseline

30% reduction in lighting energy consumption below 90.1-2004[in support of the new construction whole building goal of 50% savings by 2015, and theexisting buildings goal of 30% better than CBECS 2003 by 2025]

Goals

DOE Commercial Lighting Solutions

Value ofLighting Solutions

• Cutting Edge. Next big opportunity set in lighting efficiency is integrated quality designusing progressive technology, daylighting, and controls.

• Focus on the End-Users. Created by nationally known expert lighting designers whounderstand the needs of the various retail brands, owners, and tenants.

• Deployment Partnerships. Strong deployment and outreach program elements areworking closely with stakeholders and partners to support their goals.

• Energy Savings Decision Tool. Lighting Solutions are delivered via an interactivewebtool and tied to an energy and economic analysis to support the decision process.

• W/SF ⇒ kWh. Energy savings quantified using kWh shows savings against a series ofcommon baselines (90.1-2004, 90.1-2001, Title 24, CBECS, etc.), and represents a wayfor utilities and EEPS to provide incentives for integrated systems using energyconsumption rather than connected load.

• Actionable Solutions. Lighting Solutions include detailed technical information inperformance specification language, geared toward the A&E audience.

• This is the “How-To.” Amidst a growing set of goals and mandates, the LightingSolutions provide badly needed technical guidance on HOW to achieve these goals.

What is aLighting Solution?

Lighting Solutions= Lighting Vignette +Controls Strategies

• Lighting Vignette: Lamp + Ballast+Luminaire + Layout/Reflected Ceiling Plan(RCP)

• Controls Strategies: Controls + Installation &Commissioning guidance

The Devil’s in the details - we must bespecific to get the results we want

Expert design Energy savings

Include daylighting where possible

Lighting Solutions are Integrated Systems

Changingthe Metric

The down side of Power Density, aka watts per square foot

The time has come for an energy use metric to be widely used

Annual energy use requires data about usage over time

Solutions will vary by sector and application

Opportunities in Demand Response

Power Density kilowatt hours

Relationshipto ALG

Well-established, used, and evaluated tool geared towardsdesigners / A&E’s

History of the document and the players / sponsors

New Buildings Institute (NBI) produces the document

Applications Chapter contains lighting examples, which will bemodified and expanded into “modules”

Modules will be synergized with Lighting Solutions; different levels ofdetail

Update to ALG Applications chapter will happen in context with fulldocument update over the next couple of years

Advanced Lighting Guidelines - NBI

Criteria forDevelopment

30% savings beyond ASHRAE/IESNA 90.1-2004, which iscoincident with 50% below 90.1-2001 and the EPAct 2005 tax credit

Designs must meeting IESNA Standards, per Chapter 10 of TheLighting Handbook, 2000.

Technologies must be commercialized and reliable

Controls must have performance data for use in analysis

Lighting equipment at the cutting edge of efficiency, but will still allowfor healthy competition between manufacturers

Development process includes computer modeled lightingcalculations using industry standard software

Analysis forEnergy Savings

Analysis for energy savings goes beyond connected load to includeoperating hours and results in an estimate of kilowatt hours persquare foot per year

Controls savings must be based on empirical, measured data andcited data sets

Optimize the possibilities for demand response strategies wherepossible

Analyze the economic impacts of the Lighting Solutions, to thedegree that it is possible

Whole building modeling and analysis in FY09

Translate LPD’s into energy used


Lighting Solutions need more than LPD comparison

• Must incorporate some form of lighting time-of-use to apply controlsavings

• May involve calculation by individual component (uplight vs. downlight)

• Can accommodate capacity rate savings and utility demand reductionsavings

A true energy use savings analysis/calculation process can bestraightforward ...but….

…the data to support accurate calculations is a critical element thatcan be difficult to obtain

True Lighting Solution energy savings:


Identify discrete lighted areas in buildings for appropriatecalculations. Separate by:• differing hours of operation• specific control/no control

Apply hours of operation to area LPD• Vary by building space, function, etc.

Apply daylight dimming and other control “factors” to affected areaLPD• Use appropriate effective solar factor• Use specific control effect data – will differ by control type and

application

Calculated “Best Estimate” method

LPD-1 x operating hours-1 x Control Factor-1*+

LPD-2 x operating hours-2 x Control Factor-2*... +

LPD-n x operating hours-n x Control Factor-n

= “Total kWh/year”

Calculated “Best Estimate” Formula:

Where:1. “Control Factor” depends on control specifics and can be complicated. Must be

based on best available data.2. “Operating Hours” needs to follow varying controls and real operating differences.
