LEED) is a program that offers certifications for green buildings. The third-party verification program was created by the U.S. Green Building Council (USGBC) as a means for healthier, sustainable, environmentally friendly, more efficient, buildings, homes, and neighborhoods. In a nutshell, LEED supplies the guidelines for creating a green building. Using individual points-based rating systems that differ by project type, building projects can achieve Certified, Silver, Gold, or Platinum statuses. Project types can include new building design and construction, building operations and maintenance, interior design and construction, homes, and neighborhood development. For each project type, LEED has a list of credits with specific requirements regarding anything from building materials to bicycle storage. Points are awarded based on the degree to which the requirements are met. There are several credits that include LED lighting is the first choice of any builder trying to achieve an LEED status.

The following LEED credits relate to lighting for new construction:

full-cutoff LED wall packs that are designed to reduce glare by emitting illumination downward instead of outward. Many indoor and outdoor LED lights come with or can be used with dusk-to-dawn or PIR motion sensors to prevent wasted light.

Buildings must meet a minimum level of energy efficiency to receive points for this credit. The goal is to minimize environmental and economic problems that can be caused by high energy use. As mentioned above, LED lights are extremely efficient and can dramatically reduce a building’s carbon footprint.

SFGATE, “The Organisation for Economic Co-operation and Development (OECD) warns that, given the current trends, energy-related emissions will increase by 70 percent by 2050. This can accelerate the negative consequences of climate change, including higher temperatures and a rise in the frequency of extreme weather events.” Lessening energy consumption with LED lights and renewable energy sources will reduce greenhouse gas emissions and help prevent that prediction.

website, the USGBC states that 92.2 percent of 7,100 LEED-certified new construction projects are improving energy performance by at least 10.5 percent. In addition to other methods of energy improvements, lighting plays a key role. One building can have hundreds of lights. Using LED lights will not only help achieve an LEED status, but they will also contribute to a greener future.

Saving on energy costs and outfitting your home or office environment with new lamps and light fixtures should be at the top of your home improvement project list.  Not only do new light sources deliver a superb quality of light, they are the key components in decorative and energy-efficient lighting design.

It is an exciting time in the lighting industry.  New products are being developed every day, and LED (light emitting diode) and SSL (solid-state lighting)*  lamps and light fixtures are at the core of future illumination.

What’s more, the integration of LEDs into building and electronic communication systems is bringing everything together and enabling total control with the ease of a smart phone!

Here are some guidelines to help you answer those questions and invest wisely toward one of the greatest home improvement projects of the decade:

WHAT YOUR LIGHTING DESIGN CAN AND SHOULD DO FOR YOU…

In addition to providing optimum levels of brightness, good lighting design must also…

•Eliminate glare

•Increase comfort

•Provide continuity

•Deliver good color rendering

•Allow for adjustability

•Instantaneously make you ”feel good” with an inviting luminous appeal

Because LED lamps require so little energy to provide a great deal of illumination, the energy consumed by the bulb will not be your main concern; your main concern will be getting the desired level of brightness and light appearance.

*NOTE:  LEDs, also referred to as SSL, provide the most energy-efficient and durable illumination because they are composed of “solid state” semiconductor light emitting diodes.

1.    Familiarize yourself with labels on new bulb cartons.

Brightness (in lumens)

Estimated Yearly Cost (depends on rates and use, $)

Lamp Life (based on 3 hrs/day use, rated in years)

Light Appearance (CCT)  (warm-cool, rated in degrees Kelvin (K))

Energy Used (in watts)

Color Rendering (CRI) (measured on a scale of 0-100)

BRIGHTNESS

Brightness levels are measured in lumens to give the amount of total light created by the light source.  Beyond the lumen count, “useable” light and brightness levels are also affected by fixture housings, lenses, filters and shades.  There are clear standards set to measure the lumen output of each LED chip.  ↓

LIGHT APPEARANCE  

Light appearance or correlated color temperature (CCT) helps determine the quality of illumination.  Designated on the Kelvin (K) scale, CCT for decorative interior spaces should be in the warm white (2700-3000K) range.  Sometimes lighting in the neutral white (3500-4000K) is preferred for certain areas, such as bathrooms and kitchens.

LAMP LIFE AND THE LED

Lamp life refers to how long a light source will last once it is installed and used on a daily basis in a typical application. Lamp life ratings, based on estimates from testing,  convey the time that half the bulbs in a sampling have burnt out or dimmed below fifty percent.

COLOR RENDERING AND THE LED

The color rendering index (CRI) measures the ability of a light source to bring out the true colors in décor, objects and surfaces.  Based on a scale of zero (no color rendering) to 100 (perfect color rendering),  a minimum of 80 CRI is acceptable for interior lighting applications.  A CRI of 90+ is even better.

However, because the standard CRI measurement does not always yield true results for some LED light sources, a new standard measure of color quality is in the works:  The Color Quality Scale (CQS) may soon replace CRI for a truer account of color rendering provided by the LED light source.-www.ledlightingexplained.com, Philips Solid-State Lighting, 2010

2.    Match light fixture to light source to ensure peak performance.

LEDs small size, low-temperature emissions, and focused uni-directional beam patterns make them perfect light sources for undercabinet lighting, track lighting and pendant fixtures.

LED general and flood lighting replacement bulbs are composed of clusters of diodes to provide broader beams of light.  General service LED bulbs that are multi-directional with 360-degree angle capacity are doing an excellent job of replicating the desired illumination of old incandescent bulbs. These LED  lamps include A19, PAR, BR and candelabra light sources that are providing more light with the added benefit of tremendous energy-saving, maintenance-free illumination.

Due to their long life and durability, LEDs are excellent in hard to reach places like foyer, attic and cathedral ceiling fixtures.

*Check for compatibility with all new light sources to make sure lamps, light fixtures, dimmers and automated controls are a suitable match.

3.    Compare “apples to apples”; diodes to diodes to ensure top quality.

 Many factors contribute to the quality of the LED light bulb.   Advancements in diode technology and mass production of LED light sources are bringing costs down to make these bulbs more affordable.  However, be wary of “cheaper” LED light sources.

•COB (chip on board), the diode itself is composed of a chip that largely determines  the quality of the bulb.

Prior to being marketed in appliances, fixtures or light bulbs, LEDs are sorted into bins according to their light output (lumen output) and color temperature.  Due to the process of “binning,” LED chips vary in their quality—especially in relation to their lumen output and color, so it is important to purchase LED light bulbs and LED light fixtures from a reputable dealer.

LEDs chosen from bins with higher lumen output are of better quality.  Color temperature is determined by matching up each LED according to a chromatic line grid for a specific color temperature.   LEDs chosen from larger bins contain more color variation , so they deliver an inferior quality of light.

•LPW (lumen per watt), this measurement helps to determine energy-efficiency and efficacy

•IC (integrated circuit) drivers, the quality of the LED lamp is also dependent on the type of driver installed.  LED bulbs contain “drivers” that can fail just like the ballast of a CFL (compact fluorescent). Better driver components make for a higher quality LED light source.

ENERGY STAR-ratings ensure that the LED has met stringent testing procedures.  ENERGY STAR-rated lamps clearly identify characteristics on LED light sources to guarantee that they consistently and reliably meet the desired brightness (lumens), energy-efficiency (lumens per watt), color temperature (CCT), color rendering (CRI), and dimmability requirements.

New ENERGY STAR Regulations include:

•Consistency Control:  More standardized testing methods to improve consistency.

•Dimmability Ratings:  A lamp is either dimmable or not dimmable.  If a lamp claims to be dimmable, testing is required and it must dim down to at least 20 percent.  If it is not dimmable, it must say so on the package.

•Greater Energy Conservation:  Efficiency requirements have increased for specific lamp wattages and types.

NOTE:  The Environmental Protection Agency (EPA), along with ENERGY STAR offers rebate programs as an added incentive to help you spring into action and upgrade with LED.  Check out rebate programs in your area or contact an American Lighting Association (ALA)-affiliated showroom for more details.

When winter temperatures dip below freezing, families across the country fire up their furnaces, boilers, space heaters, woodstoves and other heating devices to beat the cold and keep their homes warm and snug. Unfortunately, the very appliances that ward off the winter chill can put you in danger of a house fire. January is the leading month for residential home fires, accounting for 21 percent of the total, according to the U.S. Fire Administration, and home heating is the second leading cause of all fires, after cooking.

Don't let your home become a statistic. Take these steps to reduce your risk of a house fire:

Clean your chimney: Creosote can build up from normal fireplace usage and clog the chimney from below; the chimney can also be clogged from above if debris falls in or if the chimney itself starts to deteriorate. Either way, it's a danger. Make sure your chimney is cleaned each year before using it.

Get your HVAC equipment serviced: You should have a technician pay a visit once a year to make sure your furnace and other equipment is in good working order. Your service professional can perform routine maintenance, repair any issues and instruct you on how to maintain your unit. Some maintenance, like replacing air filters monthly, you can do yourself in compliance with manufacturer instructions.

Careful with that space heater: Space heaters can be a convenient way to heat a small area, but they come with several caveats. Be very wary of liquid-fueled heaters -- older models shouldn't be used indoors at all, although newer models can be safe as long as you diligently follow all instructions regarding fueling and operation. Even electric heaters can cause problems, because they draw a lot of power which can overload the circuits in older homes. If you decide to use a space heater, make sure it is in no danger of tipping over, and never leave it running unattended. Space heaters account for one third of all heating fires, according to the National Fire Protection Association, so be careful.

Keep combustible material away from heat sources:  Leave a few feet of clearance between your stove, space heaters, vents, radiators and other heat sources combustibles like furniture, carpet or curtains.

Don't thaw pipes with a blowtorch: Frozen pipes are a serious problem, and thawing the ice is critical to avoiding a burst pipe and the expensive damage that can accompany it. You have a number of good options to heat the problem area -- a hair dryer, heat lamp, space heater, hot towel or specialized heat tape will do the trick. Avoid open flames, which create a fire hazard.

Test your smoke detectors: It just takes only a moment to ensure your smoke detectors work. If you do have a fire, they could save your life.
