Target Interactive Breezeway at Rockefeller Center

This a pretty cool LED installation by Color Kinetics and would be interesting to do a form of this in a children's hospital.  Here are some additional videos for the color changing LEDs if you are interested:

B-K Lighting L.O.C.K. Knuckle™ Out Performs the Competition

For those Nashville lighting specifiers and landscape architects in particular, this is a real strength of BK Lighting.  The locking knuckle mechanism allows for aiming of the fixture that has a better chance of remaining in place.  Here is a link to a cool video showing the capability.

Auditorium Lighting

The below is a blurb from Color Kinetics concerning color changing auditorium lighting.

The influence of Elvis' colorful and dramatic life can be felt from the moment the audience enters the lobby for Viva ELVIS™. The lighting for the entrance area foreshadows the opulent experience that awaits them inside the theatre. 

iColor Cove QLX Powercore color-changing LED fixtures illuminate the entry lobby's curvilinear glass ceiling, becoming more vivid as "curtain time" approaches. The 150 ft (45.7 m) long glass wall of the inner lobby area features 3,600 square feet (334.5 m2) of lenticular lenses behind fluted glass panels. This "Diamond Wall" is brought to resplendent life with 357 iColor Cove MX Powercore and ColorBlast Powercore fixtures. All lighting effects are synchronized, and one hour before the show the lobby is ablaze in color and movement. 

This theme of rich color and vibrant movement is carried into the auditorium. Color-changing, high-intensity LED fixtures in the side wall openings illuminate luxurious draperies. Wall lighting is restrained before the show begins, then the side walls burst into color, drawing the audience into the event. These illuminated walls energize the beginning of the show and then sequence subtly to more static moods throughout the performance

New LED downlight and cylinder for high ceilings

This is a great fixture to light from high ceilings where access is difficult.  So this will work for church lighting, atrium lighting, and large area entry or foyer lighting.  The color rendering index (CRI) is +90 and the LEDs will have long life compared to other sources.

LEED vs ASHRAE 90.1-2010

Be Aware


The energy conservation rules inherent in LEED are at present, based on ASHRAE 90.1-2010.  Tennessee and Georgia's codes are based entirely on the 2009 International Energy Conservation Code, and Florida's new code is a blend of what was Chapter 13 of the Florida Building Code and the 2009 IECC.  If you are involved in a LEED project in any of the three states mentioned above, you can only use the LEED rules if they are equal to or more stringent than the energy codes which have been adopted by the individual states.


Example:
ASHRAE 2010 says that you can exclude the power required for the transition lighting at the portal to a parking garage.  There is no present exclusion for the the Tennessee code.


The solution if you are doing a LEED project in Tennesse then is to take the more stringent route and count the watts for the the transition lighting.

Street and Area Light Dimming

Interesting article on the savings and energy reduction in dimming street lighting:

Leicestershire council street light scheme to save £800K

• Light dimming project continues
• Street light scheme is extended

Up to £800,000 will be saved by a scheme to reduce street light use in Leicestershire, the county council has now claimed.

The authority has already dimmed, switched off and limited the use of some of its 68,000 street lights and hopes to have altered 75% by 2014.

Officials have revised previous estimates of a £700,000 saving due to higher energy prices.

The changes were made after talks with parish councils and emergency services.

As well as saving money, the scheme is expected to prevent the release of 3,000 tonnes of carbon from energy use.

By 2014, Leicestershire County Council aims to:

• Dim about 2,000 roadside lights on main routes, between 19:00 GMT and 07:00 GMT
• Switch off about 1,000 lights, mainly on traffic routes without a night time accident record
• Switch off up to 40,000 street lights between midnight and 05:30 GMT in towns and villages across Leicestershire

Lesley Pendleton, county council cabinet member for environment and transport, said: "This is a very ambitious programme but one that has also been carefully consulted on at all stages.

"We understand that people have concerns over safety, but overnight dimming or switching off only takes place when town and parish councils have been consulted.

"We are making big savings on our energy bill, but not at the expense of public safety or security."

So far about 12,000 lamps in 48 towns and villages across Leicestershire have been switched off between midnight and and 05:30 GMT.

A further 835 have been dimmed between 19:00 GMT and 07:00 GMT, and 852 switched off permanently.

The authority also said it had reduced the maintenance costs of Leicestershire's street lights by up to £70,000, on top of the potential £800,000 saving.
