An energy-efficiency
demonstration project at the Blacow Elementary School in
Fremont, California was undertaken under the auspices of the
Rebuild America program, which is sponsored by the U. S.
Department of Energy, as well as other public and private
organizations. The Rebuild America program is committed to
"improving quality of life in
communities through energy solutions."
This demonstration
combined several innovative and unique products to save energy
while serving as a model of energy-smart practices for other
schools throughout the United States.
A multipurpose room was
chosen, in part, due to its high profile. In addition to serving
as the school’s dining hall, it hosts community and sports
events. It was also chosen due to it's poor day lighting
characteristics. The room is 57' feet long, 40' wide, with
ceiling height varying from 15' to 18', except for the ceiling
adjacent to the kitchen, at one end of the room, and the stage,
located at the opposite end of the room, where the ceiling is 8'
in height. Each lighting fixture initially contained four
(4) T12 fluorescent lights. Light meter readings were
taken in precise locations, under each lighting fixture, to
determine the lighting characteristics of the room prior to the
beginning of the demonstration. These initial readings were
taken on July24, 2003, at 11 am. The initial, or base-line
readings are represented in
BLUE numbers on the diagram
of light meter results on page 7 of this document.
Light meter readings
throughout the entire demonstration were taken under the
supervision of George Moniz, Maintenance Supervisor for the
Fremont Unified School District.
The multipurpose room was
prepared for painting by the maintenance painters from the
Fremont Unified School District. Enerchron® V40 was then
applied to the entire multipurpose room, both on the ceilings
and walls, as well as ducting located in the central ceiling
area. After the application of Enerchron® V40, the four
(4) T12 fluorescent tubes in each lighting fixture were replaced
with four (4) T8 fluorescent tubes. These T8 fluorescent tubes
are smaller and give off less light than the T12 tubes, but also
use a third less energy as the larger T12 tube, and with the
addition of Enerchron® V40 the measurable lighting throughout
the multipurpose room increased as noted by the
RED
numbers on the diagram
of light meter results on page 7 of this document. These light
meter readings were taken on July 31st, 2003, at 11AM, under the
supervision of George Moniz, Maintenance Supervisor for the
Fremont Unified School District.
The reading of 55 (left)
was taken prior to the application of Enerchron® V40 with each
lighting fixture still equipped with four (4) T12 fluorescent
tubes. The reading of 93 (right) was taken at the same
location, after the application of Enerchron® V40 and
replacement of the four (4) T12 fluorescent tubes with four (4)
T8 fluorescent tubes in each lighting fixture. This represented
a 69% increase in measurable lighting at that location with a
33% reduction in the energy necessary to produce those results.
The baseline readings throughout the multipurpose room ranged
between 28 and 64 on the light meter, as noted in
BLUE on the diagram on page
7. After the application of Enerchron® V40 and reduction in
fluorescent lighting, readings were between 39 and 93 on the
light meter, as noted in RED on the diagram.
Conclusions
Based on the results
achieved with the application of Enerchron® V40, measurable
lighting was increased within the multipurpose room by an
average of 48% when compared to the baseline readings taken
prior to any installations or applications.
When VELUX America
skylights were installed, the increase of measurable lighting
was an average of 62%, with the fluorescent lighting turned off,
when compared to the baseline readings taken prior to any
installations or applications.
With the fluorescent
lighting turned on, the combination of skylights and Enerchron®
V40 resulted in an average increase of measurable light of
nearly 90%, when compared with the baseline readings taken prior
to any installations or applications.
Other automated lighting
controls and motion sensors were installed by the other
participants in the demonstration, however, the VELUX America
skylights and the Enerchron® V40 applications had the greatest
impact on the final results and energy savings. During the
daylight hours, the room requires little or no fluorescent
lighting which equals a nearly 100% savings in energy for that
purpose.
The Fremont Unified School
District determined that these installations of Enerchron® V40
and VELUX America skylights would save the District nearly $2000
per year in this single multipurpose room. Though this room is
larger in size than the typical classroom, these results
duplicated in every classroom throughout the school would amount
to a significant savings in energy costs.
