Lessons From the Ultimate Safe House

Hard-core building owners are testing materials and technology that could change home building for the rest of us.

Energy Savings

Building a home using TF Concrete Forming Systems (ICF) saves energy and money. The higher insulation value, tighter construction, and temperature-evening thermal mass of the walls conserve heating and cooling energy much better than conventional wood-frame walls. This greatly reduces monthly fuel bills. It also allows use of smaller heating and cooling equipment, saving money in construction costs.


How much will I save?
Houses using Insulated Concrete Forms (ICF) to build exterior walls require an estimated 44% less energy to heat and 32% less energy to cool than comparable frame houses. A typical 2000 square foot home in the middle section of the U.S. will save approximately $1500 in heating and air conditioning costs each year.

In colder areas of the U.S. and Canada, heating savings will be more and cooling savings less. In hotter areas, heating savings will be less and cooling savings more.

Energy Savings

TF Forming Systems vs. Traditional Construction 

 

Finding energy savings with Insulated Concrete Forms and TF Forming Systems

Based upon 2268 sq. ft. home located in Minneapolis MN. Based upon data from Energy Wise Guaranteed Energy Saving Building Solutions, A division of Bayer Material Science. Assuming that energy costs are $.90 per kwh and Natural gas cost are at $.85 per 100 cubic feet.Based upon 6% annual energy inflation.

 

The smaller heating and cooling equipment needed for such an energy-efficient house can cut construction costs by an estimated $500 to $2000. The biggest equipment savings come with the houses that have the most energy savings.    

How do we know all this?
Based on research performed by Energy Wise Structures, houses built with ICF exterior walls require an estimated 44% less energy to heat and 32% less energy to cool than comparable wood-frame houses. A typical 2000 square foot home in the middle section of the U.S. will save approximately $1500 each year in heating and cooling costs. The bigger the house- the bigger the savings. In colder areas of the U.S. and Canada, heating savings will be more and cooling savings less. In hotter areas, heating savings will be less and cooling savings more. The energy efficient performance comes in large part from the polystyrene foam insulation on the interior and exterior of ICF walls, which range from R-17 to R-26 of insulation, compared to wood frame’s R-9 to R-15 walls. Also, TF walls are tighter, reducing infiltration (air leakage) by 50% over wood-frame homes.

 

Where do the savings come from?

TransForm and ThermoForm walls can utilize varying insulating values for its walls using polystyrene foam from an R-value of 17 to 40, compared to wood frame’s R-9 to R-15. So TF Forming Systems' walls are expected to cut the conduction losses through foundation and above-grade walls by about half, plus our walls are tighter. In industry tests, ICF houses averaged about 1/2 as much infiltration (air leakage) as wood frame.


Loss Reduction 

TF Forming Systems' walls do more than cut down on the biggest types of energy loss. The concrete gives them the heat-absorbing property, “thermal mass”. This is the ability to even out large swings in temperature. It keeps the walls of the house warmer when the outdoor temperature hits its coldest extreme, and keeps the house cooler when the outdoor temperature is hottest. The walls themselves “add back” heat or cooling energy to the interior living space of the house when it needs them most.  This contributes about 6% of the needed energy to the house for free.

Reduced equipment costs result from the expected energy savings. Since the total energy needed will be less, the furnaces and compressors that heat and cool can be sized smaller. And the more the energy savings, the greater the possible reduction in equipment size—and the equipment cost.


What's the bottom line? 

Finding energy savings with Insulated Concrete Forms and TF Forming Systems

In planning a new house you can estimate that building the walls of concrete using TransForm or ThermoForm will save you hundreds of dollars per year in energy costs. As shown in the graphs, the savings are greater the bigger the house. Heating savings are highest in cold climates, and cooling savings highest in warm climates.

You may also save hundreds or thousands of dollars in construction costs for heating and cooling equipment. Talk to TF Forming Systems today about how you  can begin using TransForm or ThermoForm to build your next energy efficient home or building.
