Lighting our Buildings more Efficiently with Exiting Technology offers Triple Bottom Line impacts.  Financial returns are gained from the monthly energy cost savings. Energy Savings in lighting can be easily be 25% to 50%,  Simple Paybacks are typically 2 to 3 years. Carbon Savings and reduced power plant emissions are good for the planet.  Improved lighting quality can have health and wellness and other productivity effects which is good for people.

The opportunity to save energy in lighting retrofit requires four decisions.

1. Decide on technology based on carbon saved and industry best practices.

Super T8, T5, Pulse Start Ceramic MH, with
"Daylight" color, High CRI, High Efficiency,
Less Heat to be removed with air conditioning
Longer Lamp Life, Reduced Maintenance Costs,
Reduced Recycling and Relamping Frequency.
More Light, Less Energy, Lower Lifecycle Costs.

2. Engineering and design. . . . One for One retrofits do not solve lighting problems

Don Northrup. Academy Award for Flicker Free Lighting, Head of Engineering for the original Duratest.  Advanced T8+ Energy Saving Long Life  Low Mercury Design.  One of the original Inventors of the "Full Spectrum" fluorescent lamps

American Environmental Products - Charles Bolta - 25 years in lighting with a number of Patents and patents pending in Lighting.  Phospor blending and Electro Magnetics consultant.  

Sunwave Lighting - Retrofit Designs, Energy Modeling  and Prototyping.  Prepare Xcel Custom Efficiency, Lighting Redesign Rebate application.  Prepare Proforma Prescriptive Rebate Application. 
Governor's Energy Office Lighting Lab consultant.

3. Select Contractors, Suppliers, and Service Providors for the Installation and commissioning phases.

Once #1 and #2 are decided, selecting the contractor poses several challenges including maintaining consistency across several buildings, sites, states?  When getting multiple bids, it is always difficult to compare apples to apples.  The lowest bidder is typically not going to be the most appropriate.

4. Decide on an appropriate Funding Mechanism.

Verify Utility Rebates
3rd party financing or leasing
Energy Service Contractor
Other Incentives

The opportunity to improve the quality of the lighting involves:

1. Remove the flicker - upgrade all T12 magnetic technology now.

- All T12 become Spectrally Enhanced Super 8's or LW T8's with
High efficiency ballasts and are delamped as appropriate for the retrofit type

- All Metal Halides - Replace with High-Output High-Efficiency Highbay Fluorescents.
2. Fine Tune the Visual Brightness, Color, CRI, and other spectral characteristics.

5000K or 6500K (3-phospors).
5000K (4-phosphors).
5300K, 5700K (5-phospohors).
5550K (6-phosphors)
3. Remove and Relocate Fixtures that are Hard to Service

Avoid future knuckle boom rental.
Abandon fixtures that are directly above racks or obstructed by structure.
Or move them so that they properly light aisles and workspaces.
Consider reflectors to direct light to where it is used.
Consider a Task Ambient Stragegy in offices
Add Automatic Occupancy Daylight Harvesting and Wireless controls.
4. Improve the Visual Productivity, Comfort and Safety for tasks performed in the space.

This may be increasing light levels in underlit areas, and decreasing light levels for areas that are overlit. This can also include adding CFL or LED Task lights or CFL uplights and adding manual on, automatic off controls to allow users to select their own appropriate light levels.

Address Glare Issues. Address Cave Effect and Dark Paint and dark ceilings.

5. Improve the health and well being of people occupying the space.

Health benefits related to lighting include a number of photobiological effects
that are not well understood. Circadian Rhythms, Melationin, Stress, Sleep quyality, Calcium metabolism, Immume System Response, Seasonal Affective Disorder and winter depression are all related to the spectral quality of Light.  A third "blue" receptor in the human eye has been recently identified and linked to our biological response to light.

EPA, Green Sports Alliance Partner for Conservation

The Environmental Protection Agency (EPA) announced on September 6 it had signed an agreement with the Green Sports Alliance to work together to address environmental challenges faced by sports venues, organizations, and teams. The two organizations signed a Memorandum of Understanding that facilitates collaboration between them on issues such as energy conservation and sustainability.

The EPA has also agreed to share tools like the Energy Star Portfolio Manager, an energy management tool that allows building owners to track and assess energy and water consumption, in order to help Alliance members improve their environmental performance.

Green Sports Alliance is a nonprofit organization with a mission to help sports teams, venues, and leagues enhance their environmental performance. Alliance members represent more than 100 sports teams and venues from 13 different sports leagues. See the EPA press release and the EPA's Partnership programs website.
