Environmental Role of Buildings
FACT #1: Our buildings consume the largest percentage of our total energy use

Environmental Role of Buildings
FACT #2: The “Appetite for Energy” of our buildings is driven
50% by space heating & cooling demands

Can We Change Cultural Priorities?
Change a culture that is
focused on the glittering
amenities?
Change a culture that is
focused on “first-cost” vs
total cost of ownership?
Not very likely!

The Secret Is In Our Name
“Insulating” “Concrete” “Forms”
Two layers of high value EPS insulation provide continuous thermal barrier
Reinforced concrete provides durable structure & protection of occupants
Lightweight EPS forms are easily shaped & adapted to architectural designs

Two ICF Use-Categories:
• Two-sided ICFs
Vertical concrete structures Flat, pitched or tilt-up concrete structures
• One-sided ICFs

Construction Time With ICF.
Thermal Resistance.
ICFs are considered by ICC and IECC as mass walls
with continuous insulation
Typical whole wall ICF assembly has an R value of
R24
ICFs exceed the requirements for all climate zones
for commercial thermal envelopes above and below
grade.
