PROJECT OVERVIEW

An outstanding thermal performance was achieved at Tilden Elementary with CarbonCast walls. Amid skyrocketing energy costs and heightened public awareness of green construction practices, more building owners are seeking environmentally friendly solutions without incurring higher costs.

Tilden Elementary Center in Hamburg, PA, is no exception. The school for kindergarten through fifth-grade students will save on heating and cooling costs with innovative precast high performance insulated wall panels engineered, manufactured, and erected by High Concrete Group.

High Concrete’s 10”-thick precast exterior walls on the 110,000-square foot project delivers R-15 performance. They use three inches of continuous XPS insulation (“ci” as defined in ASHRAE Building Energy Code 90.1-2007) sandwiched between a 4” interior wythe and a 3” exterior wythe. C-GRID carbon fiber shear grid connects the two wythes. With relatively low thermal conductivity, the carbon fiber prevents thermal transfer, virtually eliminating hot and cold spots on the interior wall preserving comfort for students.

High’s precast walls helped keep the project on schedule and under budget, both of which are critical for a public school. The project was completed in June 2008—in plenty of time for teachers to welcome students for the first day of school.

Key Project Attributes

  • Three inches of continuously extruded polystyrene (XPS) insulation sandwiched
    between the 3” exterior wythe and 4” interior wythe provide an R-value of 15.

  • The thermal mass of the panels allowed a reduction in the size and cost of the central HVAC system.

  • The use of precast concrete kept the project on schedule and under budget

"With thermally efficient wall panels, the building will be much slower to cool down and warm up, meaning the exterior environment will have less impact on energy costs.”
