Vancouver Island, BC Residential ICF Project
Three-Storey Custom Home
Single Family Residence
6300 Square Feet
5202 Square Feet of ICF Walls
100% of Exterior Walls built
with Arxx ICFs
Project Started – September 2002
Project Completed – July 2003
- This 6300 sq. ft. ICF home is located on five acres in
the Yellow Point region of
British Columbia’s Vancouver Island.
- The home’s owner, Casey Timmermans, focused on
utilizing the most efficient
green building methods when planning for his home. In addition
to choosing Arxx
insulated concrete walls, Casey also decided to use R-80
insulation in the home’s ceilings and took considerable
care choosing the home’s heating system.
- An air source heat pump is used to heat the home’s
hydronic floors, and a heat recovery ventilator has also
been installed. ICF construction maximizes the use of any
heating system, but this combination has allowed Casey to
realize tremendous monthly cost savings, as evidenced by
his utility bills during the winter of 2006 which averaged
less than $250/month.
- Since this home is located on five acres and has been
built in a wooded area, fire safety is of paramount importance.
In addition to the structure’s Arxx walls, the home
owner took a number of unique protective measures. A flame
retardant concrete tile roof was installed, plus a “fire
buffer zone” was created by building a
2400-gallon cistern in an insulated shed within walking
distance of the building.
- Energy Efficient - Arxx walls can produce equivalent insulation
values of up to R-50. This means that you can use a smaller
heating system and cooling system, and save up to and over
50% on your energy bills compared to a conventional home.
- Strength & Security - Arxx walls can be designed to
withstand wind speeds of up to 150 mph or more. Laboratory
tests simulating hurricane storm damage demonstrate that
an Arxx home can withstand wind-blown debris travelling
at over 100 mph.
- Comfort - Arxx insulated concrete walls virtually eliminate
the “cold spots” that often occur in old fashioned
frame walls, because your home is wrapped in a continuous
layer of foam insulation.
- Noise Reduction - The massive concrete core of an Arxx
wall protects your home from external noise. An Arxx wall
will reduce sound transmission into your home by 75-85%
when compared to a conventional wood frame wall.
“We don’t need to reinvent the wheel, just
put the pieces together a little bit differently. The technology
is available, but we need to put it together with some smart
economics. Green technology is just smart economics using
what we have to save money and the environment.”
– Casey Timmermans, Home Owner
