| Trinity Church has
completed it's conversion to efficient, high output LED lighting in the
Narthex, Nave, and Sanctuary. This involved replacing 227 lamps and 21
complete fixtures. Before the conversion, 30,000 watts were needed to
light these areas. Using new LED technology, we have been able to lower
this to 3,000 watts. This represents the removal of 27,000 watts per
hour off the power grid, and a substantial utility savings for Trinity!
One of the challenges to such a project has been to maintain the warm
look of incandescent lighting. Because of some recent advances in the
products available, we have been able to maintain the
"classic" look. (See picture above.)
|| One side benefit has been to improve the look and
feel of the Narthex. When the new church was built in 1989,
florescent lighting was used giving it a very cold look. By
changing out these fixtures to warm LED down-lights, not only has
energy consumption been reduced, but the look and feel of the room
has been improved!
The full conversion for these areas was not as
expensive as one might think. Most all of the labor was done by volunteers,
and labor can be the biggest cost. The church was due for a
re-lamping which normally costs about $2,200 for traditional
lamps. The cost of the LED lamps was higher (about $5,800) meaning
it was a one-time added expense of $3,600. However, we have
reduced the cost of operating the lighting by $5 per hour. Our estimate
is that our break-even point will be about a year, figuring the
lighting is used about 15 hours a week.
Although we did this re-lamping using volunteer
labor, most often we are not that lucky. When we have hired
contractors in the past, the full re-lamping runs about $2,000.
This was done every 2,000 hours of use. If the new LED lamps live
to their rated life of 25,000 hours, we will also be able to skip
about twelve re-lampings.
Going green is often a win-win situation. Over the life
of the lamps over 675 million watts of energy will be saved. In
addition, the air-conditioning load has been reduced as the heat
from the old lamps will not have to be pumped back out of the
The following list covers what we accomplished
during our Five year project:
2012: All Narthex, Nave, and
Sanctuary lighting (see above)
2013: The Conference Room has now been added to the
list of rooms converted to LED lighting. 640 watts of florescent
lighting have been changed to 78 watts of LED lighting. Although a more
modest project in nature, this room sees a lot of use. In Addition, all
three public bathrooms have been changed over dropping the demand from
400 to 144 watts.
2014: The following have all now been converted to

2016: Thirty grounds lighting fixtures were
replaced, completing our conversion to 100% LED lighting. These
fixtures are on for long durations and were drawing over 3000
watts per hour. The new LED fixtures have dropped that draw to 850
To date, our
total changeover has reduced building power
demand by 45,000
Trinity has a long history of finding ways to be kind to the environment.
Some came in the design of the new building, others were added along the
way. These include:
* Gas fired furnaces for heating and hot water. (As opposed to Oil
* Smart furnace control system that runs the furnaces at progressively
lower temperatures in moderate weather.
* Hallways lit with Skylights which eliminate the need for artificial
lighting during daylight.
* A two-stage cooling system that checks for cool air outside and if
available, circulates that as opposed to starting the main
* Motion detectors in the public bathrooms to insure the lights are
turned off after use.
* PECO Smart-Ideas thermostat system that allows cooling to be coordinated
with the utility at peak-demand times.
* Energy efficient and modern environmentally friendly office copy
* In-house recycling and separation of all waste products
We are not stopping there! Several new projects are in the works and
as ideas and funds become available, we will continue to improve the
energy efficiency of Trinity!
