Kelly Walsh High School is a public secondary institution located in Casper, Wyoming and serves Natrona County School District #1.

Opened in 1965 on a 50-acre site, the school has ample space to support the three phase renovation/redesign project. In the first phase, from May until the summer of 2015, Sampson Construction crews will build three quarters of the new school while students continue classes in the old building.

Kelly Walsh High School is not aiming for LEED certification, but it is being built with sustainability in mind. For example, the new building will integrate sun tunnel and LED-based lighting. “We anticipate our lighting power density will be less than 0.6 watts per square foot,” said Matt Arabasz, an RB+B Architects, Inc. project manager, noting that the building also will incorporate daylighting.

  • Supplying and installing 195 VELUX SUN TUNNELS and 15 Sunoptic skylights.
  • Mounting additional pre-manufactured insulated curbs in line to the crickets of the roof insulation.
  • Cutting roof deck close to sun tunnels to reduce heat loss.
