Silver Creek Middle/Senior High School
Longmont, CO
Silver
Lake Middle/Senior High School, the newest high school in the St. Vrain Valley
School District, features an attractive and practical energy-efficient design.
Open since August 2001, this 180,000 square foot facility is home to 1,200
students and accompanying staff during the school year, and sits on a 50-acre
site on the western edge of Longmont, in Boulder County.
Designed from the beginning with energy efficiency in mind, Silver Creek High
features floor-to-ceiling energy-efficient windows throughout that maximize
daylighting opportunities. Individual classrooms are equipped with sensors and
photocells that automatically sense occupancy and light levels, thus using
electricity for lighting only when necessary. The school's cooling system is
designed to allow flexible operation and to prevent the need to run a large
chiller when only a portion of the building is occupied, typically during summer
months. Chilled air is provided by multiple rooftop units, allowing for the
zoning of interior spaces.
These
design strategies provide a comfortable climate for students and staff, and save
energy and maintenance expenses while creating a pleasant and effective learning
environment. In its first year of operation, Silver Creek High School's energy
costs were $0.69 per square foot, approximately 30 percent less than typical
school facilities in the region. Furthermore, carefully conducted research has
shown that a high level of daylighting in schools is positively correlated with
student performance.1
On a broader scale, the approach taken at Silver Creek High School is an
extension of St. Vrain Valley School District's commitment to energy efficiency
and conservation. Begun in 1993, the district's energy management and education
program initially focused on conservation, primarily through an intensive
education campaign. Since 1997, attention has been directed to retrofit projects
at district facilities through a performance contract with an energy service
company (ESCO) in addition to construction of efficient new schools. This dual
approach - management techniques that focus on efficiency and education
campaigns aimed at conservation - has resulted in $4.1 million in energy savings
district-wide since the program's inception in 1993.
