Radiant floor heat is provided with 42 miles ( 68
km) of PEX hydronic tubing. Lobby floor is made
largely of recycled granite
chips — a byproduct of
commercial granite manufacturing — in a ceramic
matrix. Wall paneling is
made from 19,000 board
feet of beetle-killed Rocky
Mountain pine, treated
with a flame-retardant.
a transpired solar
heating system transfers about 75 percent
of the sun’s energy to
air flowing through
its perforations and
on to the ventilation system, at up to
10,000 cubic feet per
minute (283 cubic
meters per minute).

the Research support Facility’s exterior wall is made
from precast concrete panels for thermal mass, and
they’re insulated with 2 inches ( 5 cm) of rigid polyiso-cyanurate foam, to about R13.
a photovoltaic
system on the roofs
and parking garage
totals 1.6 megawatts.
This includes 450
kilowatts on the
roof of Research
Support Facility 1,
featuring 240-watt
modules operated
under a power purchase agreement
from SunEdison. The
remainder of the
system consists of
SunPower modules
purchased with
American Recovery
and Reinvestment
