 The University of Colorado's University Memorial Center, Boulder Colorado. The UMC is LEED EB Silver certified. Daylighting is an option on days like this. Note that the blue color in Boulder is a lot bluer say than daylight in NY or LA

Sunwave Lighting demonstrated a 5 watt per hour savings to the operations and maintenance staff. We compaired low wattage Sunwave 5550K 93CRI lamps with the replacement lamps 3500K and 4100K that they had been using for relamping existing T8 fixtures with existing electronic ballasts. They immediately noticed the difference in color and brightness in addition to the energy savings shown on the meter.
So they started installing the 5550K 93 CRI lamps in the basement in a couple offices that do not have windows. As a test. They they installed some in the Environmental Center. Next they relamped the Student Offices on the 3rd floor. Then in more offices and public meeting rooms and hallways. Then began relamping of some of the public areas. including a under lit portion of the first floor dining area on the east side. This area is underutilized perhaps because of low the light levels even though it has windows. They even found some old 4 lamps T12 fixtures and have upgraded these to 2 lamp Sunwaves. Sunwave Lighting also supplied 5000K CFL's and retrofits for expensive Ubend lamps to 2 foot F17 T8 retrofits to update hallways to spectrally enhanced technology. We calculated the simple payback on the incremental investment to be 1.25 years with 4 more paybacks at 24,000 hours and $ 0.10/kWh.

Changing a Light Bulb at BCH |

Boulder Community Hospital's Foothills Campus is the first LEED certified hospital in the nation. Kai Ablekis, Environmental Manager, takes us on a tour. This segment demonstrates several convenient answers related to changing a light bulb at the BCH hospital(s). Change a light, change a hospital, change a town, change the world. Or see it on YouTube http://www.youtube.com/watch?v=fFW4l0XV5bE. The department of surgery manager Julie Moyle has a different take, It is easier to see. The docs, especially the facial plastic surgeons, like the light. It is easier to see slight variations of color. Julie remarks, "When the staff leave the areas lit with the spectrally enhanced Sunwave lamps, it is like getting instant cataracts." She has also been looking into at staff sick days or other human resources benefits fewer headaches, fewer sick days etc. fewer mistakes... While this is not a scientific study, there is some indication that the lighting may be having a beneficial effect. Not all the lighting in the LEED certified hospital has been changed to spectrally enhanced lighting, but some of the lighting in the other campuses has also been changed to Sunwave 5550K 93CRI, so it works at newly LEED certified hospitals and at existing facitilites in the areas where visual acquity and color discriminiation are critical. For these applications, they are continuing to see the light so to speak, even though the lamps cost slightly more than the generics that they had been using. This project involved small incremental investments, starting in a dimly lit storage room and now in basement and other offices without windows, in the ERs, ORs, sterile storage rooms, Mom and Well Baby Unit, the Pharmacys and the Nursing Stations are lit with Sunwave's T8 Plus, Low Wattage, Extra Long Life, Spectrally Enhanced "Full Spectrum" lighting.

 Welcome to Sunwave Lighting. High Performance, Energy Effective Lighting Triple-Bottom-Line Lighting. Thank you for visiting. Included in this site you will find a variety of articles, links, and best practices recommendations for implementing Energy Effective spectrally Enhanced Lighting including:
- A definition and overview of Spectrally Enhanced and other Energy Effective Lighting.
- An introduction to current thinking in Lighting, both Daylighting and better Simulated Daylighting.
- Links to Lighting and Energy Authorities, Utility Rebate programs and more
- Information about the products now available for both residential and commercial applications, and
- Information about energy efficiency audits, retrofit programs, rebates, tax incentives and other third party incentives as they apply to lighting for both residential and commercial applications.
Samuel W Bodman (former Energy Secretary for the Oil Administration) made some interesting statements regarding energy efficiency in our buildings and in particular regarding our lighting systems on his the way out the door last November. Essentially he noted that there have been a lot of technical performance and efficiency inovations in the last 10 years particularly in lighting. Lighting he notes is a good canditate for energy efficiency retrofit as the lighting in over 75% of US buildings have not even been touched in the last 10 years.
