This private school, which serves kindergarten
through high school, needed an update to the multi-
purpose room and a music room. The music room's previously 8-ft. ceilings were heightened to 10 ft. by removing the drop ceiling and
cleaning up and exposing the mechanical and electrical systems. Because lunches are distributed and eaten in the room, the original sink
and laminate countertop were replaced with a more efficient angled solid surface counter. One side has a cleanup and recycling station.
The original music room was too large for the 20-student classes and lacked natural light. The space was split into two rooms — a music
classroom and a practice room. The classroom uses two windows that were formerly in a hallway. Metal-framed glass partitions on the
hall-facing walls of both rooms also help with the natural light.

The first task when updating this
house, which involved adding square
footage, was to perform an energy audit
and solar analysis. To address the ener-
gy loss for a slab on a grade home, the
remodel had to maximize the thermal
envelope. This was achieved by enhanc-
ing the existing thermal envelope at
the lid with SPF turning it into a hot
roof, as well as excavating around the
entire perimeter to 24 in. below grade
and installing rigid insulation as a ring of conductive thermal protection. The remodel also used SPF on existing walls in the area of new
work augmenting the walls with 2x2 horizontal strapping at 24 in. off center set to the inside plane of the existing exterior wall framing.
Other green elements include mechanical and water heating equipment, in addition to a Rumford refracting wood-burning fireplace.
The home achieved NAHB NGBS Emerald green certification.
