Expected to reduce energy consumption by at least 20% over a typical residence hall, West Village utilized ICF walls and precast hollow
core floors, which delivered a highly energy efficient, structurally
solid, exceptionally fire-resistant and acoustically sound dormitory.
Another key aspect of the project was indoor air quality. EPS is a stable
and durable material ideal for construction. No chlorofluorocarbons
(CFCs), hydrofluorocarbons (HFCs) or formaldehydes are used in
the manufacturing process and there is no off-gassing.

Institutional Buildings
Hospitals and clinics, police stations, fire stations and other government buildings have one thing in common - they need to survive
disasters and last for a long time. That's why many communities are
turning to ICF construction, since reinforced concrete has long been
the material of choice to resist extreme structural loading from wind,
earthquakes, floods and fires. Many ICF buildings have survived
disasters while surrounding buildings with less durable materials
have been destroyed.
Because ICF walls are integral with a concrete floor and roof system
they are extremely resistant to high loading and provide significant
structural redundancy which avoids catastrophic failure. The solid
walls act as shear walls to resist wind and earthquake loading. They
also provide protection from flying debris caused by hurricanes and
tornadoes. Because concrete and EPS are water resistant, even when a
building is subject to flooding, the structure survives. This property
protection is vital for communities to withstand and recover from
disruptive events.
ICF walls are designed using traditional design requirements of the
ACI 318 Building Code. This means architects and engineers can use
the same analysis and design techniques used on traditionally formed
concrete buildings.
Kalispell's new fire station was specified to have a design life of
100 years. The architect, CR Architecture + Design, designed the
building with ICFs for superior disaster resilience and low maintenance because of the architect's experience of living in a concrete
home. The station serves as a model for future stations and features a
16-person training room, drive-through bays, fitness/wellness room
and provisions to expand. The tower serves as a functional training
element for fire-rescue operations. The 13,000 square-foot station
was built with ICFs and features 34-foot-high gabled ends. As with
all projects, speed of construction was a deciding factor and the ICF
shell was completed in just six weeks.
After the devastating Greensburg, Kansas, tornado in 2007 that
destroyed 95 percent of the city and killed 11 people, the town leaders vowed to rebuild to stand up to future disasters and become one

of the greenest towns in America. As part of the reconstruction, the
Kiowa County Commons building was designed with ICF walls to
withstand future disaster events. The 20,000 square foot community
center houses a library, media center, offices, museum and even a
restored soda fountain. The ICF walls span up to 40 feet and the
entire structural envelope was installed in just eight weeks.

Safety is always a key concern in structures such as entertainment
and hospitality buildings, where large crowds of people gather. Fire
safety is likely the main reason to select concrete for these types
of structures. However, noise and vibration are also concerns for
entertainment and hospitality buildings such as theaters, hotels and
convention centers.
Concrete walls and floors offer the best solution to control noise
and vibration. Nothing is worse than hearing someone with their TV
blaring in the hotel room next door or hearing the deafening sound
from the action movie in the theater next to yours. That's why ICFs are
often used for entertainment and hospitality projects for their ability
to isolate and dissipate noise. The fact that ICFs can nearly eliminate
sound transmission at virtually no additional cost makes them very
attractive for any project in which peace and quiet is a selling point.
The concrete core of ICFs offers excellent noise control in two
ways. First, it effectively blocks airborne sound transmission over a
wide range of frequencies. Second, concrete effectively absorbs noise,
thereby diminishing noise intensity. Because of these attributes, ICF
walls and floors have been used successfully in entertainment and
hospitality applications. Six-inch ICF walls easily achieve STC 55
(Sound Transmission Classification) rating. Higher STC ratings up
to STC 70 can be achieved with additional gypsum wallboard or
special isolation channels. For concrete floors, most meet STC 50 or
higher and IIC (Impact Insulation Class) of 50 or higher depending
on the floor and ceiling finish.
