July/August 2015 5 As I See It by Clark Ricks The Power of Collaboration With the summer construction season in full swing, it appears that building is booming. Lumber yards and material suppliers are reporting the best sales of the decade, and within the ICF industry, reps are reporting double digit growth in the U.S. It's true that construction isn't the same as it was in '07. And that's okay. In many respects, today's environment is more favorable to ICFs, with the emphasis on green certifications, disaster resistance, and continuous insulation. Now is the time to collaborate with each other to maximize our potential. I was thinking about this the other day when I was checking up on the half-dozen beehives I keep in my back yard. Each bee's individual contribution to the hive is tiny. Experts calculate the lifetime work of a honeybee is no more than a teaspoon 6 ICF BUILDER of honey. Yet each of my hives, on a good year, will produce 50 pounds of honey to harvest; every drop was brought back one bee-load at a time from the nearby wildflower meadows. This industry is capable of extraordinary accomplishments, too. But it requires collaboration. Fortunately, the structure is in place. In May, the ICF Builder Group launched, which allows ICF professionals to take advantage of opportunities that companies lack the resources to capitalize on individually. It serves as an information resource, driving demand and raising awareness. It also provides valuable tools to association members, allowing them to take their businesses to the next level. Response has been overwhelming. In the first few weeks, dozens of the best installers, distributors, and manufacturer reps have signed up to collaborate. This issue of the magazine is also a great collaboration, It's intended to be shared with those who are new to ICFs. Articles provide a concise overview of Insulated Concrete Forms (starting on p.12). Case studies (beginning on p.16) provide real world examples of how they can successfully solve construction challenges in both residential and commercial sectors. And the product directory (p.24) has a full range of forms, bracing, and ancillary products for an ICF contractor to be successful. Success is possible to the degree we harness the power of collaboration. July/August 2015 7 In The News ICF Builder Awards Deadline Approaches Technically Speaking This is an interesting column with very little facts in it (March 2015 "Decline of the ESR"). We do not know of several brands that have dropped. Two clients dropped their reports before the inspection program was even instituted, and the claim that "an increasing number of ICF brands have allowed their ICC-ES ESRs to expire" is not factual based upon our internal information. [Additionally]the purpose of conducting the follow up inspections through ICC-ES is to enhance the quality of such inspections. As a matter of fact, we have reduced the frequency of inspections from four per year to two since the quality has been enhanced tremendously. For most manufacturers, the cost of the inspections have reduce while for some it has increased. That depends on the inspection agency manufacturers have selected to use. I do not know of a single client’s inspection fees that have doubled. Clients come to ICC-ES for the quality of the reports and the acceptance throughout the US. There are jurisdictions that do not accept the reports of other entities for a variety of reasons, not least of which is that ICC-ES is the only entity to evaluate products to ICC-ES acceptance criteria and the only entity that has institutional knowledge to conduct such evaluation.

Contractors, distributors, and ICF manufacturers are encouraged to submit projects for consideration. The annual projectof-the-year competition is being held for the 12th consecutive year. Clark Ricks, organizer of the competition, says, "We recognize that submitting projects can sometimes be a time-consuming process, and encourage those who are considering entering to get an early start on the process." Categories and judging criteria are unchanged from last year, with three residential and three commercial divisions. The entry materials, judging criteria, sample score sheet and explanatory video, will be online at www.builderawards.com beginning July 1. To request hard copy of the entry materials, call 877-229-9174. Entry Deadline is October 16, 2015. Rastra Under New Ownership in U.S. Rastra, the original EPS-and-concrete composite ICF, has new owners. In the U.S., day-to-day management will be handled by Rastra Inc. of Orlando, Fla. Russell Ferry is now serving as president of the company, with Kim Connor as national sales director. Karl Holik, who originally developed the technology and founded the company in 1972, is retiring and returning to his native Austria, although he will still be involved with the U.S. company as an advisor. U.S. Residential Construction Highest Since '05 The U.S. Commerce Department reported in May that new home construction is the highest since 2005, before the recession officially began. Multifamily construction is especially strong, and some builders are beginning to report labor shortages. U.S. housing starts rose 9.2% in April (compared to a year earlier) to a seasonally adjusted annual rate of 1.135 million. Applications for new building permits increased 10%. When compared to the month previous, single-family units climbed 16.7%, and multifamily units, including apartments and condominiums, rose 27%. “I don’t think I have ever seen multifamily construction at this pace,” says Mitch Permuy, CEO of Power Design, Inc., one of the largest full-service electrical contractors in the United States. The Wall Street Journal reports that the first quarter of the year, taken as a whole, represents a "steady but not spectacular start to 2015." Hurricane Conference Features Concrete Houses In 2014, the National Hurricane Conference included an in-depth seminar on insulated concrete homes. Based on the success of that experience, a revised version of the presentation was offered at the 2015 NHC. The class focused on the ease with which insulated disaster-resistant concrete single-family dwellings can be built, and was presented by Kenneth Luttrell, a licensed professional engineer, and Joe Warnes, who pioneered the reinforced concrete shell design in Guam. The presentation also was set to include a discussion of the structural design requirements for elevated structures recommended by FEMA. Monsour, director of marketing at RMCAO. The response from the industry has been enthusiastic, and within weeks, Builder Group already had more than two dozen members. In addition to supporting the industry, the association also provides valuable tools to members. A few of the benefits available immediately include: a members-only forum; marketing tools such as downloadable brochures; and discounted access to various expos, including World of Concrete. "If you have a passion for ICFs and a commitment to build for the future, this is where you need to be," says Ricks. "This is an opportunity for the industry to come together as a group of proven, competent ICF professionals with a unified industry voice to share our message effectively." www.icfbuildergroup.com Follow us @ICFBuilderGroup. ICF Builder Group Operational In May, a professional trade association was formed to meet the needs of the ICF professional. Called the ICF Builder Group, it is set to become the leading voice for the insulated concrete form industry, serving as an information resource, driving demand and raising awareness. A pre-launch announcement took place several months ago at the World of Concrete trade show, and now ICF-BG is accepting members. “The formation of ICF-BG is long overdue," says Clark Ricks, who is currently acting as executive director. "This is an organization that will advocate for the industry, allow ICF professionals to differentiate themselves from the amateur, and take advantage of opportunities that individual contractors lack the resources to capitalize on." ICF-BG has the support and encouragement of the corresponding manufacturer association, the Council of ICF Industries (CICFI). "The CICFI thinks we can have great synergy working together," says Ross July/August 2015 9 ICF 101 An Introduction to the Advantages of EPS and Concrete Construction Photo courtesy Michael Duerinckx Due to the unique combination of foam and concrete, ICFs homes can create significant energy savings, remarkable durability, and quieter interiors while still providing a cost-effective, beautiful building. Photo courtesy Logix ICF Insulated Concrete Forms (ICFs) are gaining popularity as an alternative building material. They offer a host of benefits, such as faster construction times, lower insurance rates, and quieter interiors, but the two primary reasons behind their growth is their remarkable durability and energy efficiency. In short, ICFs allow owners to create a building that is more comfortable to be in while only using half the energy to heat and cool as regular construction. ICF walls protect occupants and their belongings from tornadoes, hurricanes, wildfires, car wrecks and disasters. From a design standpoint, ICF technology is extremely flexible; the architecture can match virtually any style, and ICFs are compatible with all popular interior and exterior finishes. And yet, in most areas of the country, the cost of ICF construction is typically less than 10% more than wood. With careful planning and considering the utility savings, the monthly expense of living in an ICF house can actually be less expensive. The same holds true for commercial buildings. Many churches, schools, stores, and hotels have found that ICFs allowed them to build a better structure for far less than expected. The key to all these remarkable attributes is the combination of foam and concrete. Regardless of the brand of ICF chosen, all consist of two rigid EPS foam panels which sandwich a core of reinforced concrete. The concrete provides exceptional strength and thermal mass; the foam provides a continuous layer of the world's best insulation, and is an ideal substrate for many finishes. Energy Efficiency ICFs are hollow foam blocks or panels which are filled with steelreinforced concrete. They can be finished with conventional interior and exterior finishes. 10 ICF BUILDER Let's talk about energy efficiency first. For many years, ICF experts talked about "performance R-Value." These figures were impossible to verify, and the term has average frame wall is 25% wood, so even though the fiberglass or cellulose may be rated at R-13 (for 2x4) or R-19 (for 2x6), the "whole wall" insulation value is significantly less. With ICFs, the owner is assured of continuous insulation without gaps or installation mistakes. Airtight Construction: Anyone who has lived in a drafty house when a winter storm howls outside knows how signifi- cantly air infiltration can affect insulation value. For the past decade or so, homebuilders have tried to address this by covering exterior walls in a layer of paper-like “homewrap." However, frame walls are made from dozens of individual components which guarantee that outside air will be able to infiltrate the living space. ICF walls, though, are virtually airtight. Even hurricane-force winds can’t force their way through four to six inches thankfully disappeared. But the concept remains true: The actual, real-world performance of an ICF wall far exceeds its nominal insulation value. This is due to a combination of three factors: more insulation, less air infiltration, and highmass walls. Higher Rated, Continuous R-Values: EPS foam, from which ICFs are made, is one of the best insulating materials yet invented. The R in “R-Value” stands for thermal resistance, and the higher the R-Value, the better the wall is at stopping the flow of heat. Homes built using wood frame construction typically have exterior walls rated between R-13 and R-19. ICF walls, on the other hand, have foam with tested insulation values of R-22 or R-26. (A frame wall would need to be a full 12 inches thick to achieve a similar rating!) Some ICF manufacturers offer foam inserts for even thicker sidewalls, with tested values of R-32 or even R-40. Additionally, ICFs offer continuous insulation. With frame construction, the July/August 2015 11 Photo courtesy Nudura Richardsville Elementary in Bowling Green, Ky. is America's first net-zero school. Built with ICF walls, it generates more electricity than it uses, and it was built at a cost comparable to any other new school project. 12 ICF BUILDER erly-sized high-efficiency HVAC system. Disaster Resistance With a solid, monolithic core of steel-reinforced concrete, it should be obvious that ICF homes, schools, and other buildings perform well when disaster strikes. What is more remarkable is the number of real-world examples. ICF homes have survived arson attempts and wildfires, hurricanes and tornadoes, storm surge, drunken drivers, even explosions at close range from TNT. A few years ago, tired of absorbing massive losses from natural disasters, the insurance industry set up a program to encourage homeowners to build more The three ICF homes on this street in San Bernardino, Ca. are easily identified, after a 2007 wildfire reduced the neighboring wood-frame homes to ashes.

Thermal Mass: Many historic buildings in the American Southwest have pleasantly cool interiors even when the hot summer sun has been beating down on them for hours. The secret is in their adobe walls—usually several feet thick—that take hours to heat up. And when the sun sets and temperatures drop, the stored-up heat keeps the interior pleasant through much of the night. This phenomena, called thermal lag or temperature damping, is due to the mass of the walls. Like adobe, ICF walls take advantage of thermal mass. Even a modest ICF home uses dozens of yards of concrete, and that weight creates thermal lag in ICF structures, moderating temperature swings. A few years ago, the Portland Cement Association (PCA), conducted a study of 58 single-family houses across the U.S. and Canada. All were less than six years old. Half had exterior walls constructed with ICFs; the other half were traditional frame homes of a similar size built nearby. The study found that the ICF homes used 44% less energy to heat and 32% less energy to cool than comparable frame houses. That means a typical 2,000-sq.-ft. ICF home in the central U.S. would save $200 in heating costs and $65 in cooling costs each year. There are other factors in play as well. Maximizing energy-efficiency in an ICF structure requires some other important steps, such as the use of adequate attic insulation, quality windows and doors, and a prop- durably. The Fortified…For Safer Living program specifically encourages ICF use. Chuck Vance, IBHS "Fortified" program administrator, says, "We're impressed with the superior wind-load capacity of an ICF wall. It also has other benefits as well, including resistance to fire and fewer problems with water damage.” Vance notes that the program is designed to prevent damage from all types of natural disasters in all areas of the country. Because of this, the criteria for a “Fortified” home varies regionally, based on the natural disasters most likely for that area, such as hurricanes in the southeast or tornadoes in the Midwest. Regardless, ICFs will stand up to whatever threat is greatest in that region better than any other technology. In some areas of the country, insurance companies will give discounts for “Fortified” When a drunken driver lost control and slammed into this home at an estimated 90 mph, the ICF wall kept the owner safe, and damage to a minimum. homes, or for ICF homes in general. While hard figures are hard to come by, anecdotal evidence indicates that the savings are real. “I have an ICF builder in Myrtle Beach, South Carolina that builds to our guidelines” says Vance. “Every home he builds gets a discount from the local Farm Bureau affiliate and South Carolina’s Wind and Hail Pool. Those two discounts add up to significant savings.” The owners of a 4,800-sq.-ft. ICF home in Florida report an $18,000 annual savings as a result of credits attributed to the ICF construction. His annual wind and general liability insurance is “$2,200/year plus some change,” less than he pays for the wood frame guest home across the street that’s less than half the size. “The insurance industry understands value of a reinforced concrete ICF structure in a hurricane prone area,” says Sandy Esterle, owner of the design/build firm that constructed the home. As one might suspect, building a hurricane-proof home requires more than just ICF walls. Windows and doors are the Photo courtesy Safe Harbor Design/Build The owners of this ICF home in Lighthouse Point, Fla. Report that the disaster-resistant forms have reduced their insurance premium by $18,000 annually. most vulnerable, and tests at Texas Tech University show that 2x4 wood studs easily penetrate wood frame and even brickveneer walls. (See the video on our website.) The boards were shot at speeds up to 80 miles per hour—barely hurricane force. Tornadoes frequently have windspeeds in excess of 200 miles per hour, and currently, concrete is the only material that can stand up to such severe winds. Many experts believe ICFs are the most cost-effective—and aesthetically pleasing—way to protect occupants and their belongings from wind-related natural disasters, building all exterior walls from ICFs, using impact-resistant windows or metal storm shutters on all openings, and a disaster-proof roof. As noted above, ICFs stand up to other disasters equally well. 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. On one suburban street in San Bernardino, every home on the block was burned to the ground, with the exception of three ICF homes, which a newspaper photographer captured standing virtually unscathed amid the charred wreckage surrounding it. Insulating concrete forms resist fires in several ways. The most obvious is their structural concrete core that will not weaken, warp, twist, or burn regardless of the fire's heat. In so-called “fire-wall” tests, ICF walls withstood temperatures of up to 2000°F for as long as 4 hours without any sign of weakening. In contrast, wood frame walls typically collapse in an hour or less. The concrete core also prevents fire by slowing the conduction of heat from one side of the wall to the other. Contrary to popular belief, the foam used in ICFs will not burn. It will melt if exposed to high heat, but it will not contribute any fuel to the fire. In fact, it is virtually "selfextinguishing," thanks to a flame retardant all of the leading ICF manufacturers add to the EPS foam. Other notable examples of ICF homes that have withstood disaster include a beachfront home in New Jersey that withstood Superstorm Sandy, despite having it's siding scrubbed off by the pounding waves, and a Gulf Coast ICF house that withstood a 20-foot storm surge generated by Hurricane Katrina that swept the rest of the neighborhood down to bare foundations. ICFs are so disaster resistant that the U.S. military conducted blast-resistance tests using 50-lb. charges of TNT. The results were impressive enough that they now frequently specify ICF construction for "force protection" requirements. Sound Absorption About 10 years ago, 75 ICF homeowners were surveyed about the features they appreciated most in their ICF homes. It’s no surprise that energy efficiency and disaster resistance topped the list. But benefits numbers three and four were comfort and quiet. In fact, more than 60% of ICF homeowners mentioned the quietness of their homes, versus only 2% of their wood frame counterparts. This is due, once again, to the sound absorbing qualities of EPS foam. Pieter Vanderwerf, who conducted the study, says, “Many homeowners said their biggest surprise in moving into an ICF house was the noise difference… The ICF owners told two common stories over and over again: ‘I looked out the window and saw the traffic on the road, but I couldn’t hear it.’ And ‘While talking with my neighbor one morning, he asked if the thunderstorm the night before woke me up, too. But until that moment I never even realized we’d had one.’" Continued on pg. 30.

It's certified LEED-Silver. MULTIFAMILY 1ST RUNNER-UP Photos courtesy Ken Williams LAKESIDE RESIDENCES The town of Keswick, Ontario, about forty miles north of Toronto, was facing a shortage of affordable housing. The waiting list of singles, seniors and families needing housing assistance in this town was years-long, reportedly topping 1,500 individuals a few years ago. So when a developer suggested building a beautiful, energyefficient, low-maintenance apartment complex for some of them on a prominent site that had sat vacant for decades, the city council took notice. Ken Williams, territory manager for Fox Blocks, which provided the ICFs for this project, says, "The building site was on the main street in Keswick surrounded by turn-of-the-century shops and houses. The design of the building had to blend with the area as well as be soundproofed from the road traffic and meet LEED-Silver requirements." During the design stages, Elite Building Group, an installer with extensive experience in mid-rise ICF construction, was brought in as a consultant. They, in turn, brought Fox 14 ICF BUILDER Blocks' LEED consultant and technical team to the table. They resolved the developer's and general contractor's concerns regarding construction timelines, building code acceptance, quality standards, potentials for cost overruns, and LEED compliance. Funding was secured through a variety of grants, subsidies, and government programs, and in mid-2012, the project got underway. Williams says, "Construction of the ICF scope of work was scheduled for spring but started in October, so this was now a complete winter build." The project's design is fairly complex when compared to typical low-income housing. The architecture features an all-brick exterior, radius-topped windows and doors on all sides of the building, and a free standing 14-foothigh bell tower over the front entrance. Fortunately, the ICF installation crew from Elite was experienced, and worked though all of these issues without delay. They also innovated a few developments. For instance, the two levels of underground parking required exposed concrete walls, but with the rear of the building right on the lot line, the use of conventional forms was impossible. Instead, this was formed with ICFs, and the EPS stripped off the inside face afterwards and painted. This technique was also used for the elevator shafts and stairwells. In another innovation, they used brickledge blocks to create the corbels that support the stairwell landings. By December, the York regional newspaper, which was following the project closely, reported that "the $19.2-million Lakeside Residences facility is moving forward without any significant delay or setback, despite being a complicated site with excavations going into the hill." Each of the six above-ground floors used 1,200 lineal feet of wall and had fifty 90º corners, four 45º corners and 17 T-walls intersections. Williams reports that the number of ICF window and door blockouts exceeds 450. Giraffe bracing, used to hold the walls perfectly plumb while the concrete cured, was easily crated and moved from floor to floor as work progressed. The exterior façade is supported on corbel blocks installed at the base of the first floor. Even with the winter conditions, Elite crews wrapped up the ICF scope of work in 112 days—two months ahead of schedule. No winter heating was needed to keep the concrete from freezing. Nearly all interior walls are ICF, which reduces sound transmission but also required the installer to stack and brace more than 50 corners on every floor. The project included more than 450 window and door openings, including several massive arches. The floors are precast concrete planks, a popular choice for ICF midrise construction. July/August 2015 15 The 97-unit low income housing development was completed in May 2014, and was filled immediately with qualified residents. Heather Piggott moved in to her fifth-floor unit in June. “It’s fabulous. I love it,” she says, adding the attention to accessibility in everything from parking to laundry facilities is a key factor. She says daily life in her wheelchair is much easier and convenient thanks to the state-of-the-art modified facilities at the complex. A choice view of the lake makes her apartment even more of a slice of heaven. The $19.2 million facility used more than 111,000 sq. ft. of ICF (72,500 sq. ft. in the exterior walls and nearly 40,000 more in the interior walls between units). Floors are precast concrete. The project easily met its goal of LEED Silver certification and may possibly achieve gold level when the final points are awarded. "This project has set a new bench mark for this type of housing," Williams says. "This is the first large-scale ICF public housing project in the area, and it was built to LEED-Silver standards. This was also the developer's, engineers', architects', site foreman and City of Keswick's first experience with ICFs but it won’t be their last. Much educating was needed at all levels with all parties during the projects development, but the result is that the City of Keswick has a beautiful new downtown building that will be the standard that other buildings will need to meet going forward." 16 ICF BUILDER Project Statistics Location: Keswick, Ontario Type: 97-Unit Low Income Housing Size: 83,000 sq. ft.

Simon & Harris specialize in ICF construction, and have built nearly 50 ICF homes in the region. After several discussions, Harris took the owner on a tour of a completed ICF home. He says that before the tour was concluded, the owner was on the phone with his architect, directing him to rework his plans for ICF. The project team elected to use Nudura products, based on the builder's familiarity with the brand. Sickmeier, an experienced architect but unfamiliar with the finer points of ICF design, faced the challenge taking the existing blueprints (drawn by him) and adapting them for ICF construction. All photos courtesy Simon & Harris The design of this beautiful Indiana home was inspired by the stately Victorian summer homes on the Northeastern coast of the U.S. The multiple wrap-around porches—oriented for optimum lake views—turrets, and bay windows provide visual interest while reflecting the proportions and aesthetics of the owner. It's much more spacious than it appears—11,500 sq. ft. spread over three levels—and careful consideration to the design, structure, create a distinctive, family-friendly home. Plans were drawn up by Ron Sickmeier of Henry-Sickmeier Architects, over the course of three years. The original version called for a 2x6 frame home on an ICF foundation, but when Josh Harris, co-owner of Simon & Harris, received a phone call from the 18 ICF BUILDER This involved allowing for thicker exterior ICF walls, adjusting the installation of the bay windows, and reworking some of the door and window placements. The roof connections and internal steel beam supports also needed to be revised. In the end, the decision not only led to a stronger, more energy-efficient home, but was also more economical. Harris says, "Our price for ICF construction was below the price quoted by a competitor to build with stick frame construction with spray foam." Constructing a home of this size on a heavily wooded hillside lot was challenging, to say the least. The footprint has nineteen 90º and ten 45º degree corners, as well a radius wall that sweeps across the front porch of the home. The surveyor used GPS satellite coordinates to locate these corners precisely. Work began in July of 2012, and proceeded smoothly. Two second floor ICF walls have no supporting wall on the first floor. Seen in these before-and after photos is the second-story turret, cantilevered out over the front porch, which generated considerable attention.

The complex roof has multiple gables, hips, and valleys, made even more difficult by the steep (12:12) pitch. A second-floor turret, now the homeowner’s office, is supported by steel beams that cantilever over the porch. Harris says, "Until the final porch posts were installed, this cantilevered section of the home was quite a topic of conversation. It appeared to be floating in space." The homeowner confirms, “Our house did raise a few eyebrows during the 18+ months of construction, and apparently became the talk of the town”. The attention led to at least one favorable story in the local newspaper. The homeowner continued to investigate other energy-saving strategies. High efficiency doors and low-e argon-filled windows were installed. The home has a geothermal heat pump for the HVAC system, with separate units on each floor for independent control of the heating, air conditioning, and hot water. The owner calls it "practically free air conditioning" in the humid summers of southern Indiana. Just as much attention was spent on the interior. A sweeping “Gone with the Wind” formal staircase leads from a central rotunda to the second level. Wide baseboards and trim were used balance the 10-foot ceilings and match the deep window sills inherent with ICF construction. Timeless, unique, one-of-a-kind details are tastefully placed throughout; imported marble fireplaces, mosaic tile floors, bronze staircase banisters, stained glass windows, and antique furniture pieces allow the owner to enjoy the very best of the past, now and in the future. The exterior finishes were chosen with Victorian influences in mind. Louisiana Pacific and Nudura collaborated with the installer on this home to work out "best practice" installation techniques for installing LP's Smartside engineered wood shingles on ICF. Harris says, "It's sometimes been a challenge in the building industry to be assured that [a certain] product will be compatible with ICFs. This is changing slowly as more ICF projects (residential and commercial) are developed and successful." Harris summarizes, "This home was completed in May 2014, and meets or exceeds the standards for a graceful, attractive and energy-efficient home. Its design is classic with loads of architectural details and design elements, both inside and out. Challenges of terrain, elevation, plan revision, and structural concerns all were addressed in a professional and timely manner, culminating in a home that draws positive attention from all who see it." Sickmeier, the architect, now considers himself a “convert" to the benefits of ICF, and now makes an effort to encourage other builders that “ICF is a good consideration”. Most importantly, the homeowner is thrilled with his home. He says, “I cannot express how happy I am that I chose ICF for the construction of this house. Although we have only lived here a little less than four months, the benefits of ICF are becoming quite clear. We feel exceptionally safe staying in this house regardless of the weather conditions, and the insulation provided by these walls has proven to be exceptional, as witnessed by our electric bills." He goes on to add that the walls nearly eliminate the noise from the nearby road, and that “there is no movement or creaking” of the walls that would occur in a traditionally framed home. He concludes, “When an ICF house is properly built, I see no comparison to the benefits provided by ICF as compared with any other type of home construction.” July/August 2015 21 SMALL RESIDENTIAL FINALIST ROBERTSON HOME the top of the gables. Edward Sandelin, of Sandelin Custom Homes, the general contractor, notes, "This created an extremely attractive high gabled ceiling through the living room and off the kitchen." Tim Rainwater, the ICF installer, carefully coordinated the window and door openings, as well as the placement of the propriety heavy joist hangars which supported the gluelam beams. To increase the homeowner's safety in a worst-case-scenario tornado, Rainwater and his crew installed an all-concrete safe room that doubles as a walk-in closet. It has ICF walls on all four sides, a steel door and a 6” thick concrete roof cap. Nudura ICFs were selected for this job. Sandelin says, "The accessibility of the manufacturer's representative and the professional engineered schematics made the decision." He reports that the distributor provided "just great support." "In fact," he says, "the manufacturer's representative actually visited the site three times during the build." Soils in North Texas can be difficult, and this home site was no exception. The engineering required 70 piers to support the foundation. To save costs and save the valuable topsoil, the owner "harvested" this with his dozer and backhoe. This resulted in large hole, All photos courtesy Edward Sandelin When Guy and Heather Robertson discussed building their dream home in rural Texas, two priorities consistently rose to the top: energy efficiency and tornado resistance. These factors are understandable, considering the extreme Texas heat and the fact that North Texas in recent years has become a part of “tornado alley." But aesthetics were also important. Fortunately, ICFs can easily meet all three criteria. The finished home is light, airy, and open, with extensive glazing in back. This was carefully calculated and based on the home's orientation. For instance, the west side of the home has minimal windows, since this is exposed to the hot afternoon sun. Large roof overhangs further reduce direct light into the home. The roof is insulated with 5 ½ inches of open cell spray foam and topped with Galvalum standing seam metal roofing, which can reduce radiant heat by approximately 30-40%. The HVAC system was high efficiency 20 SEER all-electric with a heat pump and motorized dampening. Combined, this means that in the heat of the Texas summer, utility bills average $80 a month. (On an annual basis, they average $60 per month, very reasonable for a home of just under 3,000 sq. ft.) The open floor plan is made possible by the use of massive gluelam beams, which are supported by ICF walls that extend to 22 ICF BUILDER Project Statistics Location: Stephenville, Texas Type: Custom Home Size: 2,888 sq. ft.(floor) ICF Use: 2,500 sq. ft.

In addition, the client planted only southern latitude, drought-tolerant plants, further reducing the project’s need for using limited well water for irrigation. Sandelin says, "This home was instrumental in spawning three new ICF projects in the North Texas area because the owners are so very open to allowing prospective ICF clients into their home and by their willingness to discuss and share their thought processes in the design of their own home. We have gone from an occasional ICF home as requested by an educated homeowner to determining that the technology is the best that we can offer our customers and we have begun marketing and building ICF homes as the principle offering in our line of homes.” He concludes, "This home serves as an excellent example that a smaller ICF home can be built economically and provide longlasting comfort for a young couple for years to come."

They have resorted to inserting internal ties, external strapping and bracing to gain needed strength. This adds cost in additional materials and man-hour rates. The engineering staff at Fox Blocks added more length to their corner blocks and introduced the heaviest cross tie corner bracket on the market. Adding these features to our large/strong interlock stops rotation and movement within the blocks during the pour and adds strength to eliminate blowouts. Having this bracket and no fewer than two ties from each corner in all 45˚ and 90˚ block eliminates the need for additional strapping or bracing. Being 16” longer than other ICFs allows you to eliminate one full straight block for every three Fox Blocks corners used, saving you money. Like all Fox blocks, the extended corner blocks are reversible so when you ask for a corner you will get the correct one every time. All blocks have ties at 8” on center and are available in 4”, 6”, 8”, 10”, and 12” cavities.

Vibrators Oztec www.Oztec.com 1.800.533.9055 An addition to Oztec’s ICF consolidating equipment is the RebarShaker. Placed over the top of vertical steel reinforcement, the RebarShaker vibrates at 10,000 - 12,000 vpm, ensuring excellent concrete consolidation inside insulating concrete forms. The RebarShaker allows contractors to use a stronger, lower slump mix and still produce void-free walls, since the shaker gives the trapped air time to escape. The Rebar Shaker also tends to slowly rotate the rebar; packing concrete between the rebar and form with excellent bonding. Walls with wide rebar spacing will be more effectively consolidated using a combination of Oztec’s internal flexible shaft vibrators and the Oztec RebarShaker. Waterproofing Epro Spray-Applied Waterproofing for ICFs www.eproserv.com 1.800.882.1896 Epro Services Inc.’s products have waterproofed more ICF foundations than any other fluid applied system in the industry. The reason is that Epro provides a complete system from a water-based, seamless, high performance liquid membrane to extremely durable and tough HDPE protection courses and drainage composites that just work better than any other system. Unlike sheet (peel-and-stick), membranes, which have seams and rely on an adhesive for bonding, the Epro fluid applied membrane forms a seamless barrier even at the most critical points (transitions, terminations and penetrations) and provides its own tenacious adhesion. The protection course and drainage composite protect the waterproofing membrane while controlling and directing hydrostatic water pressure away from the foundation. Their HDPE construction provides unparalleled chemical resistance guaranteeing a long lasting system. This adds up to the best ICF waterproofing system solution. July/August 2015 29 Photo courtesy Blue Home Design Radius walls, such as those on the Massachusetts home above, are much simpler to build with ICFs than any other construction method. Most ICFs with a six-inch concrete core have STC ratings of 50 to 55. Insulated 2x4 wood stud walls with 3 ½ inches of fiberglass batt are rated near 38. The difference between an STC rating of 38 and 50 may not seem like much, but the decibel scale is logarithmic, so 50 decibels is ten times as loud as 40 decibels. In realworld terms, only about one-quarter to one-eighth as much sound penetrates an ICF wall when compared to wood frame. This has become a major selling point in the commercial sector. Theaters and apartment buildings use ICFs to eliminate sound transmission between units, and developments near noisy industrial sites are selling quickly, thanks to ICFs sound sound-absorbing qualities. Design Options As already noted, insulated concrete form construction can be adapted to virtually any residential or commercial project. Adapting a plan for ICFs typically starts with stretching the exterior walls outward a few inches to accommodate the thicker walls. Other architectural flourishes are actually easier with ICF. For instance radius walls, which are difficult to build with frame or block construction, Only about one-quarter to one-eighth as much sound penetrates an ICF wall compared to wood frame, making them popular for movie theaters, such as this one in California's Central Valley. are simple. Long clear spans can be easily accommodated, because the walls can carry the loads and steel beams these designs require. Windows can be made larger in seismic zones, and winter construction becomes possible in northern regions. While ICF walls look dramatically different from plywood-sheathed frame construction, they're actually easier to work with for most exterior finishes. The foam substrate is perfect for cement-based stucco or textured acrylic finishes. Brick, stone, and manufactured stone are also applied more easily to ICFs than frame, as no additional vapor barrier is needed (in most regions). Siding—vinyl, wood or cement board—are also popular. It's as easy as fastening the material to the ICF furring strips, clearly marked on the outside of the forms. Costs Incredibly, the cost of living in an ICF home is no higher—and may be cheaper— than living in a regular house. Nationally, an ICF home is estimated to cost 3% to 5% more than frame building. That’s about $10,000 for a $250,000 house. Financed with a conventional 30-year loan at 5%, that amounts to an additional $55 on the monthly mortgage. However, because the homeowner will be saving at least that much on energy bills, the actual monthly cash outlay is less. In other words, when energy costs are considered, it’s actually less expensive to live in an ICF house. All of the other benefits—like disaster-proof walls, quiet interiors, and less maintenance—are added bonuses at no extra cost.
