Efficiency Vermont is a Registered Provider with The American

Institute of Architects Continuing Education Systems

(AIA/CES). Credit(s) earned on completion of this program will be reported to AIA/CES for AIA members. Certificates of Completion for both AIA members and non-AIA members are available upon request.

This program is registered with AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product.

Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

Learning ObjectivesLearning Objectives

By the end of this program, participants will be able to:

• Tell the difference between LED products available in the market.

• View samples of current LED fixtures and light sources

• Compare LED fixtures and light sources to both CFL and traditional

sources

• Learn how to properly evaluate LED lighting in terms of actual light

output, color, dimmability, etc.

• Understand proper application of LED lighting in both new construction

and retrofit projects.

• Compare LED products by evaluating the spec sheets.

• Understand the DOE Lighting Facts label.

Have we lost our minds????

• Only has one channel

• Only has one volume setting

• Costs 30 to 50 times more than normal TV

• Will be completely obsolete in 6 months

Determining Factors

Identifying Quality Residential LED LightingIdentifying Quality Residential LED Lighting

• Color Temperature (CCT in Kelvin degrees)• Acceptable range is 2700K – 3000K for most interior applications

Important Characteristics

• Color Rendering (CRI)• Acceptable range is 80+ for most interior applications

• Dimmability• Is it really dimmable? •With what type of dimmer?

• Accurate Replacement Capability• Is it truly a viable replacement for existing technology?• Is it worth the additional cost?

• Flexibility and “Sustainability”• Will it be obsolete in less than a year?

• Distribution• Is the spread of illumination the equal to existing technology?

LumenThe amount of light generated by a light source, at the source.

EfficacyLumens per watt.

Color TemperatureThe outward appearance of the color of a light source (i.e. warm or cool).

Color RenderingThe ability of a light source to render colors in comparison to other light sources of a similar color temperature.

IECC 2009

•State of Vermont enacted Code as of January 1, 2011.

•Lighting section requires that 50% of the lamps in all installed sockets must meet minimum efficacy requirements.

•Do you select “dedicated” technology or “retrofit” technology?

•Does the town inspector require documentation during permitting process?

•Does the town inspector actually understand and follow the code?

•What are the implications if you do not comply?

•Only CFL and some LED lamps (or fixtures) meet the minimum efficacy requirements.

IECC 2009 – Efficacy Requirements

• 40 lumens per watt for lamps 15 watts or less.

• 50 lumens per watt for lamps 16 – 40 watts.

• 60 lumens per watt for lamps over 40 watts.

LED vs. CFL

• Good for intense, directional lighting such as highlighting

• Instant “on” to full intensity

• Full range dimming

•No mercury

•Very high initial cost

•Emerging technology with potential to be obsolete quickly in favor of advanced product

LED

• Good for wide-spread, softer illumination

• Not instant “on” to full intensity

• Not true full range dimming

• Mercury disposal issues

•Affordable initial cost

• Established technology that has improved greatly
