WRAC tennis courts ace an upgrade

Muffed serves or missed shots on the indoor tennis courts at the Wenatchee Racquet and Athletic Club (WRAC) can’t be blamed on poor lighting anymore. The 37 noisy, dim metal halide light fixtures previously used on two of the indoor tennis courts have been replaced with quiet, bright, instant-on T5 fluorescent light fixtures.

Manager Evy Gillin said the old lamps required long warm-up times and had to be left on constantly when the club was open. The new fluorescents provide bright light instantly and are on switches that can be operated at the club’s front desk.

On the other two courts, the original lighting system with 44 outdated, eight-lamp T12 fluorescent fixtures has also been replaced with 32 six-lamp T5 fixtures, emitting far greater light levels.

Energy savings from installing fluorescents and LEDs (light-emitting diodes) at the tennis and racquetball courts, at the club’s outdoor pool and in the club building are estimated at 362,618 kilowatt hours per year, enough to power 16 Chelan County homes. The WRAC received $43,602 from Chelan PUD’s Resource$mart program to help offset its total cost of $64,293.

WRAC member Brian Wengreen, a retired PUD engineer, volunteered to coordinate this project with help from more than 40 member volunteers. Their volunteer labor made the project affordable for the club, Gillin said. Key to those efforts were Brian Gundersen, Dick Lester, Randy Smith, Ted Brisbine of Brisbine Electric and retired electrician Heinz Schlipf.

One more project is planned to complete relighting the entire club.

Stemilt upgrade is a fruitful endeavor

Stemilt managers say they expect to quickly recoup their investment in new energy-efficient lighting through lower electric bills at their processing/packing/shipping plant on Euclid Avenue in Wenatchee.

“I can see clearly now” is the song employees are singing at the Stemilt processing plant on Euclid Avenue in Wenatchee after lighting was upgraded in over 300,000 square feet of space.

OK, they’re not really singing, and you couldn’t hear it over the hum of forklifts and conveyor belts if they were. But Steve Frodsham, the fruit processor’s electrical administrator, says employees love the new lighting at the sprawling plant where apples, pears and cherries are received, processed, stored and shipped.

Energy-efficient LEDs on motion sensors now illuminate many of the cold storage rooms, providing immediate light when someone enters. Frodsham said he knew it was time to replace the plant’s numerous metal halide lights, so he tested fluorescents before moving to LEDs. But even the most modern fluorescent tube lamps failed to come on quickly enough to light rooms for forklift drivers as they moved in and out. Cold was a factor, he said, since most of the 100-plus storage units are kept at a chilly 32 degrees. (LED lights love the cold. They last longer and are brighter.)

Fluorescent lights are being used above packing lines, in hallways and elsewhere, though, and they’re a big improvement, Frodsham said.

Beckstead Electric of Wenatchee installed the lighting. Jim White, Chelan PUD engineer, arranged funding from the PUD and documented energy savings.

White said 1,400 light fixtures were retrofitted or replaced at a cost of $605,704. Chelan PUD’s Resource$mart program provided $435,048 of the cost. Projected annual savings is 2,900,000 kilowatt hours — enough to power 145 homes.

“This is an old facility,” Frodsham said. “A general lighting concept was never part of its evolution. When Jim and Beckstead (Electric) came in we were able to engineer it to suit our needs. A lot of areas that didn’t have sufficient light are now well-lit.

“Lighting makes a big difference in how people feel and how they perform,” he added. “We couldn’t be happier with the outcome.”

Durable, affordable, cheerful holiday LEDs

Posted in Electronics, Energy conservation on October 29th, 2013 by Susan – Comments Off

LED holiday lights – once difficult to find and expensive to purchase — are showing up in more and more stores at affordable prices.  At the same time manufacturers have improved the selection, producing bigger and brighter bulbs and new color options.

Here are some reasons to consider LED lighting for your holiday decorating this year:

  • Energy-efficient – 0.08 watts per LED C7 multicolor bulb (compared with 0.48 watts for an incandescent mini-light and 6.0 watts for a standard incandescent C7 bulb.)
  • Long life span – up to 100,000 hours or more used indoors, half that outdoors, and some manufacturers provide a limited lifetime warranty.
  • Safety – no chance of combustion since the bulbs are cool to the touch, regardless of how long they are left on.
  • Sturdy bulbs – the epoxy lenses are virtually indestructible.

Check out our brochure on LED holiday lighting, and happy holidays!

PUD brings discounted LEDs to some stores

The latest in energy-efficient lighting — LED bulbs — are now part of Chelan PUD’s retailer discounts. Save on  LEDs, CFLs and low-flow showerheads at your local retailer.

Look for the Simple Steps Smart Savings signs at local stores. Customers will find prices already marked down on LED (light-emitting diode) and CFL (compact fluorescent) light bulbs, indoor hard-wired fixtures and low-flow showerheads. Markdowns range from about 50 cents below suggested retail for general purpose bulbs to up to $7 on energy-saving showerheads. LEDs are marked down by about $3 per bulb.

Quality LED products can last 25 times longer than an incandescent bulb and use 75 percent less energy. Although they’re more expensive than CFLs, there is no mercury in LED bulbs so there’s no concern about hazards in your home or the environment. Learn more about LEDs.

Simple Steps Smart Savings graphic(Note: Not all stores are participating in the LED promotion. Home Depot and Lowe’s in Wenatchee and BiMart in East Wenatchee are participating, and the Walmart stores in Wenatchee and Chelan are tentatively scheduled to join the LED promotion this fall.)

The savings are brought to you by Chelan County PUD through a regional program designed to make energy-efficient products more affordable for consumers. Items available through the Simple Steps Smart Savings program are:

  • LEDs – many are fully dimmable
  • Twist CFLs – regular and mini twists
  • Specialty CFLs – reflectors, globes, candelabras, torpedo bulbs and outdoor lighting
  • Fixtures – indoor hard-wired fixtures
  • Showerheads – Those using 2.0 gallons per minute or less

Can you guess which lighting system uses the least amount of power? The top photo shows the lighting near the pharmacy on the first floor of Wenatchee Valley Medical Center before lighting efficiency improvements were made. The bottom photo  shows the first-floor hallway after the fixtures were outfitted with new fluorescent and light emitting diode (LED) bulbs. The lights in the lower photo use 60 percent less energy than the original lights. Modern lighting technologies can save energy AND provide better light.

All lights in the eastern portion of the building (not including the surgical center), and parking lot lights, have been replaced. Chelan County PUD is paying about half the cost of the lighting improvements through its Resource$mart program.

This WestSide story has a happy ending

No Sharks, no Jets — just super-cool systems for saving energy in new high school building

Students moving across Ninth Street to a remodeled WestSide High School this fall will be treated to state-of-the-art concepts in lighting and energy efficiency not available at any other buildings in the Wenatchee School District.

It’s a little gift to students and staff at the alternative school. They’ll enjoy the very best after being housed in what has been the worst of student facilities in the district.

It's not much to look at yet, but a remodeled WestSide High School will feature open rooms, skylights, LED lighting on daylight sensors and other energy-efficient equipment. The recessed area in the concrete floor used to hold the Eagles Lodge dance floor.

A swap with Wenatchee Valley College provided the 18,000-square-foot building, which is the former Eagles Lodge. The school district’s WestSide property – originally built 50 years ago as dormitories for the college – is now in WVC’s hands.

The school district is using reserves of more than $4 million to fund the move: $1 million for the property exchange (the Eagles building had higher value in the swap) and $3 million to remodel it into the new WestSide High School. An $810,000 state grant is paying for energy measures that will make the high school super-efficient.

The building has been gutted in preparation for construction work that will begin in mid-February. But Bryan Visscher, director of Facilities and Risk Management, has no trouble picturing what’s to come.

“Architects developed an open concept for common areas,” he said, pointing to the high ceiling. The building will feature “team rooms,” he said, gesturing toward the center of the vast open building, which will use movable, convertible walls as space for working on team projects. Classrooms, offices and counseling rooms will dot the perimeter. Students will get a real kitchen for the first time, along with a classroom kitchen for instruction in cooking and life skills. The new WestSide also will include art rooms and a resource center with computers and electronic library.

The entire building will be outfitted with light-emitting diode (LED) lighting on daylight sensors. As daylight increases, lights dim. As sunlight wanes, lights grow brighter.

The building will get plenty of natural light, Visscher said, through new windows and skylights.

Other energy benefits include an advanced, low-maintenance, highly efficient VRF (variable refrigerant flow) system for heating and cooling. In addition to offering superior comfort and efficiency, the system can take excess heat not being used in the building and heat domestic water, Visscher said

“We’ve taken an already cool design and just put it over the top,” Visscher said.

He’s planning an energy dashboard near the main entrance to display energy savings to visitors.

On a scale of 1 to 100 used by the Environmental Protection Agency’s Energy Star Portfolio Manager program, the old building scored a 6, Visscher said. He’s hoping to take that to a 75 or higher, which would give the school district one more Energy Star award to add to its collection of six awards received under Visscher’s supervision. The awards recognize outstanding improvements in the energy efficiency of schools, churches, hospitals and other public and commercial buildings.

WestSide Principal Kory Kalahar said a new school has been planned for many years. Forte Architects visited with WestSide staff several times, he said, to get ideas and feedback. “They really wanted the new building to help students maintain the atmosphere and culture they’re used to,” Kalahar said, noting that WestSide does not use bells or lights to let students know when periods end and begin. “It’s a more relaxed atmosphere. We have standards, and they’re high standards, but the atmosphere is different” than a traditional high school.

Staff should be able to move into the remodeled building in mid-August, with students following on Sept. 1.
