Education
Protecting children's health, safety and welfare along with providing comfortable learning environments are important factors when
building a new school. Reinforced concrete and polystyrene, the two
main components of ICFs, are inert and do not off-gas like other
building materials, making it an ideal system for school buildings.
The combination of insulation and thermal mass result in a building
with more consistent temperature which vastly improves occupant
comfort. In addition, concrete and polystyrene are noncombustible
which means schools are safer.
Concrete is the most fire resistant of all construction materials
used today which means ICF construction offers a significant safety
advantage over wood and steel frame construction. Concrete cannot
burn like wood or soften and bend like steel under fire conditions.
All ICF manufacturers involved in commercial construction have
tested their products in accordance with standard fire testing protocol,
including ANSI/UL 263 and ASTM E119. Typically, 4-inch ICF walls
achieve a 2-hour fire rating, 6-inch ICF walls achieve a 3- or 4-hour
fire rating and 8-inch and thicker ICF walls exceed a 4-hour fire rating. Generally, the assemblies tested include reinforced concrete with
a minimum compressive strength of 2,900 psi and 1/2-inch gypsum
wall board on each side.
The EPS used in ICFs is flame retardant and is approximately
five times better than wood at stopping flame spread from materials
burning in close proximity. EPS is completely unable to support a
flame without an outside flame source. This is what provides the
extra margin of safety for occupants and fire fighters over wood and
steel construction. EPS used for ICFs is strictly required to have a
flame spread index of less than 25 and smoke developed rating of less
than 450 when tested in accordance with ASTM E84 & ANSI/UL
723. ICF companies that maintain national evaluation reports from
ICC-ES or other accredited testing agencies have all conducted a long
list of materials tests in order to comply with national safety standards.
The 550-student Richardsville Elementary School achieved the
distinction of being the first net-zero school in the United States in
2010. A net-zero building is one that is extremely energy efficient

and has a renewable energy source on site which produces energy that
is returned to the energy grid. To accomplish this, Sherman Carter
Barnhart Architects reduced the average energy use from 60.5 kBtu
per square foot to 18.2 kBtu, 75% less than the ASHRAE 90.1
standard. This involved investment in technologies such as natural
day-lighting, solar orientation, efficient lamps, photovoltaic panels,
a geothermal system, and thermally-superior ICF walls and concrete
floors to maximize energy performance. ICFs also reduced sound
transfer between classrooms, the gymnasium, cafeteria and music
media center. In addition, due to the school's location in Tornado
Alley, ICFs will help keep the building's occupants safe in the event
of a natural disaster. The 72,000 square foot, $14.9 million project
was constructed within budget and ahead of schedule thanks to ICF
construction. The investments paid off - in 2012 the school district
received a check for over $37,000 from the utility company for electricity it generated.
A design-build project with Whiting-Turner, BGK Architects and
Mackey Mitchell Architects, the 230,000-square-foot student West
Village student housing complex at Texas Tech University implemented
fast track construction methods to deliver the project within an incredibly compressed schedule - 16 months for design and construction.
Opened in 2014, this $54.8 million project contains 455 beds, community lounges and conference rooms, as well as designated study
rooms. The complex was designed to meet LEED certification serving
as a model for Texas Tech's newly adopted sustainability initiatives.
