Windows and doors are framed using “bucks” (box outs that create a frame for a window to fit inside. Windows are placed to maximize cross ventilation when weather permits. The house is exceptionally airtight, so we also installed a Fantech HRV (Heat Recovery Ventilator). An HRV brings outdoor air inside and preheats it with stale indoor air before it enters the home – fresh air in, stale air out. The HRV could also be fitted with specialized filters to address toxic air problems outside the home. During extremely humid weather, we do have some minor condensation/mildew in the basement if I don’t keep the air moving.

What makes up an ICF form?
These homes perform well in flooding, so they are appropriate for coastal areas. The reinforced concrete also makes them suitable for highly seismic zones. If you live in an area that is prone to natural disasters, an ICF home could give you peace of mind. The savings and payback of an ICF home are primarily dependent on what you are comparing to and how well the home is built.
Plumbing and Electrical in ICF Construction
Insulated concrete form walls have been tested up to 2,000°F for up to four hours in fire conditions. An ICF house’s payback and savings depend primarily on what you’re comparing to and the construction quality. If you have an ICF home with a very tight building envelope, you will probably experience higher savings.

ICF walls cut an estimated 30-40% off the energy used to heat and cool a house. ICFs create a thermal barrier that outperforms traditional construction. Firstly, ICF homes are incredibly energy-efficient, resulting in smaller mechanical equipment and reduced monthly costs for the homeowner. In fact, downsizing HVAC systems in ICF homes can lead to a reduction of greenhouse gas emissions over the life of the structure compared to less efficient wood-frame construction. Don’t forget that the house plan is designed to be built with ICF (Insulated Concrete Forms) construction, which provides superior thermal efficiency and strength. Concrete block houses have a number of benefits that make them an attractive option for many homeowners.
Fireproof home? ICF technology offers solution to California's destructive wildfires
For as long as we’ve been building homes they’ve been susceptible to all kinds of problems. Not only are common building materials likely to fail in event of extreme weather, they also tend to cost more and take longer to build with. Since the concrete walls have a lot of mass and are insulated to slow heat transfer, they absorb and release heat slowly.

The Dovetail Deck provides continuous-composite-action over the joists, this reduces (and mostly eliminates) cracks in the floor above the joists. For seismic conditions TOTALJOIST provides a simple method to collect floor loads at the perimeter of the floor and transfer them into the support system. It will melt if exposed to high heat, but it will not contribute any fuel to the fire. In fact, it is virtually “self-extinguishing,” thanks to a flame retardant all of the leading ICF manufacturers add to the EPS foam. When a raging wildfire swept through the suburbs of San Diego in the fall of 2007, it forced more than half a million people from their homes and destroyed more than 2,000 residences.
In this example, both homes are 2,500 square feet, and costs are calculated with a 2% inflation rate over a span of 30 years. An important cost for homeowners to consider is the monthly utility bill. ICF homes are much more energy-efficient and cost far less to maintain compared to wood-frame homes. ICF homes provide a solid solution to high energy costs and extreme weather. The need for energy-efficient and fire- and earthquake-resistant structures is largely responsible for the rising trend of ICF construction in California. Overall, this floor plan is great for those who want plenty of space inside and outside their home.

Having intact air and moisture barriers is an essential prerequisite of modern energy-efficient construction, and the ICF system automatically creates them. Buildings usually leak at joints between the various building components, and walls tend to have a lot of such joints. On the other hand, concrete that’s too wet creates additional pressure on the walls, which may cause blowouts.

That teamwork streamlines the effort to rebuild while the building materials also reduce the cost. Overall, ICF homes increase your home’s comfort, reduce your monthly energy bills, and, most importantly, reduce your environmental footprint. The type of foam used in insulated concrete forms varies from project to project.
Twenty years ago, HUD estimated in this paper that ICF construction was 5% to 10% more expensive than wood frame construction. Gaps in the typical batt insulation in wood-framed structures disproportionately reduce its effectiveness. The buildings are free from drafts that can plague conventional construction, increasing comfort. You can also make the house more disaster-resistant by adding a fire-proof roof well-anchored to the structure, along with impact-resistant windows and metal shutters where appropriate.
Using extra insulation on the interior compared to the exterior can be a better option for above-grade walls. The finishes are then attached to fastener strips lodged in the insulation. A contractor can quickly complete many steps of the construction process since the insulation and fastener strips come with the ICF blocks.
They are more than 10 times stronger than framed structures, and several times stronger than CMU “cinder block” construction as well. It’s a natural result of having exterior walls with a core of solid, steel-reinforced concrete. Architects can design an ICF home to look just like a wood-frame house and still take advantage of all the added benefits of building with concrete. The floor plan can match virtually any style, and ICFs are compatible with all popular interior and exterior finishes. This floor plan features 2 bedrooms, 3 baths, 2 walk-in closets, a living room, a dining room, a utility room, a living room, a dining room, a covered porch, and a kitchen.
However, these two cons are typically mitigated by lower operating costs and cheaper installation. On the other hand, the pros of building an ICF home in California are myriad. These benefits range from impressive energy savings to incredible disaster resilience. If you are a prospective California homeowner interested in ICF construction, follow below to learn more. On top of being one of, if not the safest building material on Earth, ICF’s are also extremely energy efficient. Especially in basements and cold weather areas, ICF’s are able to keep heat in and cold out with astounding efficiency.
In this case, the vapor barrier is already built-in within the ICF walls, so no additional work is usually necessary. In disaster-prone areas, where insurance may not be readily available, insurance costs are very much lower. Because the strength of this reinforced concrete construction is much greater than the strength of a wood-frame structure, it can survive disasters. In addition, the mass of insulation and concrete makes for a very quiet interior. Only about one-eighth as much noise gets through the ICF walls as through wood-frame building walls.
ICF construction is easier than wood-frame construction and prevents many common chances for human error. Because the forms, especially those from Fox Blocks, are modular blocks, they’re easy to assemble and projects move quickly with fewer errors. The many benefits of a concrete house built with insulating concrete forms (ICFs) are available for only slightly more than the cost of traditional wood-frame construction. ICFs are simple to assemble and they consolidate several construction steps into one.
The efforts have resulted in a drop in the state's per capita electricity consumption by 24 percent over the last 40 years. In comparison, the per capita energy consumption for the whole country decreased by only 4 percent. The ICF House Kit floor plan features a master bedroom, walk-in closet, bathroom, indoor kitchen, living/dining room, laundry/pantry room, outdoor kitchen, and garage on the first floor. The second floor includes 2 bedrooms, 2 walk-in closets, 1 bath, a storage room, a mechanical room, a laundry room, a bar, and a living room.
