Greybull Elementary School
Greybull, WY
The Big Horn County School District No. 3 built a new Greybull Elementary
School to replace the former school building, which was built in 1919. The old
Greybull Elementary School building, now a historic property, had very high
energy bills (reaching $50,000 per year), poor indoor air quality, and minimal
daylighting. The new school was designed and built to achieve LEED-Silver
Certification under the U.S. Green Building Council's LEED for Schools program
(LEED NC, Version 2.1). As the first LEED Certified School in Wyoming, Greybull
Elementary demonstrates how a high performance school can be constructed, built
and operated with reduced environmental impacts and energy costs, while offering
a healthy, productive learning environment.
Located in Greybull, WY, the elementary school was completed in August 2007
with a total project cost of $8 million for the 36,000 square foot facility
($222 per square foot). The Wyoming Energy Office paid for the LEED
Certification costs at Greybull Elementary. The school is designed to achieve
nearly a 50% reduction in energy costs compared to a typical school built to
current energy code requirements.
Below is a list of sustainable design features, organized by LEED category.
The school achieved 38 points, making it eligible for LEED Silver Certification.
- Building materials were sourced from nearby suppliers and sustainable
sources.
- Water conserving fixtures are used in bathrooms, faucets and the
cafeteria kitchen.
- The school features a geothermal exchange system for heating and
cooling, combined with a well-insulated building envelope and energy
efficient windows.
- Natural daylighting is used in 85% of the interior spaces, including all
classrooms, the cafeteria and multi-purpose room, and gymnasium. Indoor
lighting levels are designed to automatically adjust based on the level of
naturally available daylight.
- High efficiency fluorescent fixtures (T5 and T5HO indirect luminaires)
are installed in classrooms, offices, and corridors with occupancy sensors
throughout the building. The construction specifications restricted the use
of carpets, glues or other components with high quantities of certain
chemicals, to protect indoor air quality.
- The school will recycle plastic, paper, glass, cardboard and metal, even
serving as a community drop-off point for community recyclables.
- Educational information is provided for students, including exposed
piping and mechanical systems with labels to illustrate energy efficient
features.

The School has raised awareness among teachers, students and staff about the
importance of conserving resources and protecting the environment. It has also
served as a model for future school projects in other Wyoming School Districts,
and surrounding states.
