From my perspective

Photovoltaic panels at work on the roof of the Richardsville School. Photography Joshua White.

The ICF schools here do not cost any more to build than traditional schools, about $225 per square foot. This is attainable technology with funds available for all people and all communities. The Kentucky Board of Education now requires new schools to be constructed using NUDURA’s Insulated Concrete Forms, unless the designers can provide a reason why they choose not to use it. The biggest bonus might be these schools also are disaster resilient. The insulated concrete forms can withstand tornadoes well in excess of the minimum design criteria required in Kentucky. Wrote Jill Lewis Smith, President of Civic Consultants Inc., Louisville, Kentucky

It’s an unusual back-to-school issue this year. The tragedy in Moore, Okla., on May 20 influenced the topics. As a child in elementary school in Oklahoma City, I often heard the emergency sirens sounding as little feet rushed to huddle in hallways much like those at Plaza Towers Elementary School. It is not a good childhood memory to recall and I shiver to think of those young ones who lost their lives. I only hope that parents will demand safer and better schools to protect our families and our future. We know that the methods it takes are available. Thank you to architect, Kenny Stanfield, and his team for supplying a wealth of information for the cover story on “Building Better Schools”. This feature covers the first net-zero energy school in the U.S and the topics of school safety and sustainability. The landmark Richardsville School project was called to my attention by Jennifer Boyce at NUDURA, who was preparing additional information for their website. Naturally, when I was planning the issue, I talked with the CEO of NUDURA who had recently visited Oklahoma. He commented: “The industry has proven that it is possible to build energy efficient schools, on time and on budget when compared to traditional methods,” said Murray Snider, President and CEO of NUDURA. “We also know that with a little bit of extra thought we can design the reinforced concrete walls to create a safe environment as well. So why would anyone consider anything less when rebuilding schools in areas where extreme weather conditions occur again and again?” In the Concrete Monthly Supplement read about how Joplin Schools are building dual-purpose safe rooms in 14 of their buildings to put safety first for students, teachers, staff and even the community. The below grade feature written by Barry Herbert this month also touches on safe rooms and other benefits of basements worth knowing about. That’s the “Beauty of Basements.” As the industry looks forward to the 6th Annual ICPSC event coming up in Georgia on September 12-15, this issue is the perfect time to share some information about the new polishing standards introduced this year by CPAA. I talked with Brad Burns about what that means. Some of the great examples are in school buildings because the advantages of concrete polishing for reducing maintenance costs, improving indoor air quality and minimizing slip-fall hazards have been well-documented in LEED™ for Schools. Enjoy the bright days of summer!

MAKING JOPLIN SCHOOLS SAFER By SHERRY BOYD

23 Below Grade 27 Concrete Monthly 29 Association News

The Joplin School district has instituted a wide-reaching program that calls for 14 multi-purpose community safe rooms in schools throughout Joplin. The district developed the approach for improved storm safety with some guidance from FEMA and funding through their Hazard Mitigation Grant Program (HMGP) to offset part of the costs. The program includes concrete safe rooms that double as gymnasiums. Also, a new field house at the football stadium and a band / choir room are being built with reinforced concrete to double as safe rooms. When these reinforced concrete safe rooms are completed students and teachers will have immediate access to shelters strategically placed in schools

throughout the Joplin Schools system, and excess space has been allocated to provide community shelters. “Missouri Governor, Jay Nixon, has been very involved in the rebuilding program, along with Dr. C.J. Huff, the superintendent,” said Mike Johnson, Director of Construction for Joplin Schools. “What we have learned is that traditional construction doesn’t cut it. There is no safe place, unless schools provide specifically designed safe rooms. We learned that safe rooms could be built to serve multiple purposes, such as gymnasiums, auditoriums and other areas that have community uses evenings and weekends.” Johnson continued, “Historical records show the areas more prone to risks, such as Joplin is. It only makes common sense to target

these areas making investments so that parents know their children are safe at school.” He added, “Here in Joplin, residents voted to raise taxes to support the rebuilding of safer schools.” The catalyst for the comprehensive safe room building initiative came from a record setting, multiple-vortex EF5 Tornado that bore down on the southern side of Joplin, Mo., on May 22, 2011. That Sunday evening the damage became catastrophic. The unoccupied Franklin Technology School and Joplin High School were completely destroyed. Later, school officials who reviewed the site as seen from cameras in hallways were aghast to realize the danger existJOPLIN SCHOOLS continued on page 28

RICHARDSVILLE ELEMENTARY EARNS TOP MARKS FOR SAFETY, SUSTAINABILITY Text by SHERRY BOYD Photography by CHRIS PHEBUS AND COST SAVINGS

B

UILDING THE FIRST NET-ZERO ENERGY (NZE) SCHOOL IN THE NATION AT A COST COMPARABLE WITH TRADITIONAL CONSTRUCTION REQUIRED INNOVATIVE DESIGN SOLUTIONS TO MINIMIZE ENERGY DEMANDS AND RADICALLY REDUCE BOTH CONSTRUCTION AND OPERATING COSTS FOR THE 72,285-SQUARE-FOOT RICHARDSVILLE ELEMENTARY SCHOOL. THE NEW SCHOOL SUCCEEDED SO WELL, IT WENT BEYOND THE GOAL OF GENERATING AS MUCH CLEAN ENERGY AS IT CONSUMES. BY THE END OF 2012, THE DISTRICT RECEIVED A CHECK FOR THE ELECTRICITY IT GENERATED – A NET-POSITIVE RESULT.

“Warren County Public School district was very forward thinking in their goal of reducing energy costs to free up more budget dollars for education and teacher salaries,” says the lead architect, Kenny Stanfield, AIA, LEED AP, of Sherman Carter Barnhart Architects. Sherman Carter Barnhart Architects in collaboration with CMTA Engineering Consultants were able to reduce first costs for the building through several means. The compact floor plan minimized the amount of perimeter wall and reduced the HVAC load. The high bay areas for the media

center and a dual-purpose gymnasium/cafeteria were centrally positioned, eliminating attic space and relocating heat pumps to mechanical closets. Insulated Concrete form (ICF) construction allowed a shorter construction schedule. These cost savings and others allowed expenditures to be shifted to a geothermal system for heating, cooling and water heating with a much lower energy use. Actual building energy consumption for Richardsville Elementary School is measured as an annual energy use intensity (EUI) 18.2 kBTUs per square foot and the energy September 2013 • Concrete Homes

generation has exceeded consumption by 26.5% since January of 2012 when the full solar energy system became operational. The renewable energy system consists of a 208 kW thin-film photovoltaic (PV) array located on the roof in February 2011, which was augmented by 140 kW crystalline PV panels that sit atop a shade structure built in the parking area. It was designed to have a 20-year life cycle. (By comparison, the average school in Kentucky consumes EUI 73 kBTUs per square foot annually.) However, the success of the renewable energy system is only a part of the story. Richardsville Elementary is built of steel reinforced monolithic concrete walls using 6-inch and 8-inch NUDURA insulated concrete forms (ICF) with an R-value of 28 – resulting in less energy use for heating and cooling. The metal roof has a 6-inch layer of polyisocyanurate insulation providing an R-34.9 rated roof. Interior walls are also ICF, providing sound attenuation of particular importance in hallways, the gymnasium and media center. By the time the Warren County Public Schools District was ready to build the new Richardsville School to replace its aging predecessor built in 1946, the school district was 8

already committed to ICF construction. Safety became a consideration since the area had historically experienced high winds and severe storms The Warren County Public School district had made the pivotal decision to switch from traditional masonry to ICF construction and hollow core concrete plank floors. In 2005-2006, the district built Alvaton Elementary, using insulated concrete forms from NUDURA, which contain 50% recycled materials, reduced construction waste and provide sound attenuation. With each successive project, the district wanted to improve upon the sustainability and energy efficiency that they could already see. “Since our firm has been working in partnership with the school district as their architect for over 20 years, we had the advantage of looking closely at each school after it was built to understand where the greatest energy use areas are,” said Stanfield. “Looking at data the local TVA subsidiary gathered, we discovered that the kitchen used 22% of the energy demand. This allowed us to focus on improvements.” In collaboration with the school district, the team looked more closely at improvements in the kitchen. In addition

to using Energy Star-rated kitchen equipment, combi-ovens were installed in lieu of fryers and skillets. The combi-ovens use steam instead of grease, also eliminating the Class 1 hood requirements necessary to capture grease vapors. Reducing energy use further, windows are placed to maximize use of daylight and reduce lighting costs and light shelves are used to minimize glare. Tubular skylights, also called “light tubes”, are strategically situated. The supplementary artificial lighting is controlled by sensor systems. Motion sensors also adjust ventilation relating to room occupancy. All of this contributes to reducing energy use. Richardsville Elementary became the first all wireless school in the Warren County Public School district. First cost savings were realized by eliminating the power/data wiring infrastructure for classroom computers and removing 1,000 square feet from the floor plan that would have been allocated to the computer center. The server rooms would have consumed significant energy, and the new computer carts give teachers more mobility in using computers anywhere throughout the school. One of the unexpected benefits is involvement by both students and teachers in learning more about our environment. Richardsville Elementary school has hallway displays about Solar Power Generation, Water Conservation and Recycling that are making sustainability topics a part of every day conversations for first graders and their parents. Throughout the school, environmentally friendly finishes were specified. Polished concrete floors, a popular choice 10

for high-traffic areas, were specified for the majority of classrooms, hallways and workspace, another first in the school district. The low-maintenance polished concrete choice provided another surprising benefit; maintenance was reduced significantly enough to eliminate a member of the custodial staff. The gymnasium floor was constructed of hardwoods recycled from the old building along with renewable bamboo. Sherman Carter Barnhart Architects is convinced of the advantages of ICF construction for many areas beyond energy efficiency and reduced operational costs. ICF performs well for long-term durability, sound attenuation, reduced waste and materials use and providing a streamlined construction schedule even during winter months. “We were told ‘you can’t do it’.” We were able to dispel the myths,” says Stanfield. “Using green design does not have to create an added cost. We can look at the advantages and data from many successful projects. The five most energy efficient schools operating in Kentucky, including the Net-Zero Richardsville School, are all ICF schools designed by our team. That should take away any fear of the unknown. There is a track record to provide showing you can achieve all those goals.” According to the architect, “With ICF there is not just one advantage, there are multiple advantages. Based on our experience, it would be hard to see a better alternative. The schools built this way are designed and constructed to withstand severe weather conditions. During storms, parents know their children are safer in an ICF school than at home.”

construction specifications and the terminology of polishing concrete would evolve to help architects, property owners and contractors communicate about the final appearance and performance criteria. During 2013, the Concrete Polishing Association of America (CPAA) released standards and specifications for the steps and defining terms like grinding, honing, friction rubbing and burnishing. CPAA established standards for specifying Finished Gloss as Levels 1 through 4, with each having varying degrees of sheen and clarity. Add to that the different classes of aggregate exposure that can create a variety of appearances. For many years, specular gloss, the appearance of light reflection alone, has been the accepted method for gauging a quality floor. The finished gloss levels identified by the CPAA incorporate specular gloss along with “distinction of image” (clarity). The clarity of reflections identified by distinction of image is not as easily manipulated as specular gloss. The new Finished Gloss levels will help architects and designers specify higher quality. Some of the CPAA’s specification also reinforces what 14

manufacturers have been saying for the past decade. Ideally a 4000-psi floor with a flatness of 50 provides the best surface for polishing. The floor should be prepared and cured in accordance with ACI 302.1R-4.The floors should be cleaned and protected from damage prior to polishing. Due to the work of CPAA, information on the way of looking at and understanding the appearance and the abrasionresistance of concrete can be measured, quantified and more importantly specified. The details can be found on the CPAA website: concretepolishingassociation.com/. This summer CPAA announced an educational collaboration with the International Concrete Polishing & Staining Conference (ICSPC). In September CPAA will offer courses for Tradesman Certificate and Craftsman Level 1 Certification Classes at the ICPSC event. The Tradesman Certificate is an introductory course with classroom education providing a foundational understanding of the process of polishing, tooling and products types. The Craftsman Level 1 course combines hands-on training with the classroom education that prepares contractors to do problem

SAFE, SOUND AND SOLAR-POWERED A NET-ZERO ENERGY SMOKY MOUNTAIN HOME MEETS THE RETIREMENT GOALS OF THE OWNERS.

Text by KELLY STOKES

FTER DECADES OF RESEARCH INTO INSULATING CONCRETE FORMS AND RENEWABLE ENERGY, MIKE AND PHYLLIS BARTER FINALLY ARE ENJOYING THE FRUIT OF THEIR LABORS, A NET-ZERO HOME THAT PAYS FOR ITSELF. THE BARTERS ARE LIVING THEIR DREAM IN THEIR 3,658-SQUARE-FOOT ICF HOUSE, SITUATED ON FIVE ACRES WITH DRAMATIC VIEWS OF THE SMOKY MOUNTAINS. Mike often said, “When I retire, I’m not paying energy bills!” During the decades he worked for nuclear power plants, he dreamed of living in a net-zero energy house that would produce as much energy as it uses and more. The Barters spent four years searching for the perfect property with a good southern exposure suitable for a bank of solar panels. As soon as the Barters purchased their five-acre lot, Mike began installing a 5-kilowatt photovoltaic system. Comprised of 20 solar panels, the system generates 240-volt AC power that is sold to TVA, their local electric company. The cost of their electricity usage is subtracted from the power that the solar panels generate. Once their solar hot water heater was 18

Concrete Homes • September 2013

installed this summer, it tipped the balance in their favor and they now owe nothing to TVA each month. By next winter, they anticipate a credit of $400 to $500 on their electricity bill, which means that the initial purchase cost for the solar panels will be recovered in 5.8 years. Beyond energy efficiency, the Barters had other reasons for choosing insulating concrete form (ICF) construction for the safety and durability of their own home. After Hurricane Katrina devastated the Gulf Coast in 2005, the Barters wanted to help people rebuild safer, sturdier homes. “When Katrina hit the Biloxi coastline, there was about a three-mile stretch where the only home left had been started using ICF,” says Phyllis. “The only damage was to the windows.” The Barters both became certified ICF installers and purchased an IntegraSpec distributorship, a venture they had been considering since they learned about insulating concrete forms in 1995. They soon built seventeen homes along the coast, providing forms, training, and advice for property owners.


Providing energy self-sufficiency, the 5-kilowatt system is comprised of 20 solar panels that generate 240-volt AC power.

GETTING STARTED With six years of experience in ICF construction, the Barters designed their home themselves. Phyllis produced the layout and primary drawings. Mike used his background in mechanical engineering to make sure it was structurally sound in every detail. While Mike was setting up the solar panel system, Phyllis began digging out for the foundation with their tractor to save on labor costs. At first, they lived onsite in their RV while building the home, then moved into the basement during the summer months because it was cool. When the Barters started laying the forms, they realized something was wrong with Mike’s health. After a trip to the emergency room they learned that he required heart bypass surgeries and would need six weeks for recovery right in the middle of constructing their dream home. Not wanting him to get discouraged, Phyllis continued the project with a little help from friends and neighbors. “At 61-years old, I put up 60% of the walls myself,” she says with well-earned pride.

ICF SIMPLICITY & RELIABILITY IntegraSpec’s forms are flat, expanded polystyrene (EPS) rectangles that are lightweight and lock together using a patented design. “One of our neighbors’ sons, who was fourteen, came over and helped lay the forms,” shares Phyllis. “It says a lot about the simplicity of the process.” In addition to help from family and neighbors, a contractor and prospective homeowner were sent by a local distributor to be trained in the process onsite. “With a little bit of training, IntegraSpec is like putting together Lego blocks. You have an outside wall and an inside wall and you slide this web down and you create a block,” she says. “For someone that’s got any common sense, it’s not that difficult to put up.” The ready-mix concrete truck came out three times to pour each of the different levels. The Barters boast that they didn’t have a single blowout during the whole process, a feat their concrete supplier had never seen before in any other ICF project he had poured. Mike Barter attributes avoiding blowouts to the design of the IntegraSpec system combined with their own knowledge of bracing the stress points. The September 2013 • Concrete Homes

grooving in the polystyrene surface is designed to adhere to the concrete and perform well during concrete curing. ENERGY EFFICIENCY The three-level home has a footprint of 1800 square feet. In addition to constructing the exterior walls, ICF was used to form the footer, reducing the temperature of the basement floor. One section of the basement, “The Hot Room,” houses the solar hot water system, which has a 4.2-year pay back to recoup costs. Water is heated and stored in three 55-gallon barrels, contained in a box insulated with two-inch foam within the ICF-walled room. Water is circulated through a solar-powered coil system, providing their hot water needs, as well as general heating for the home. Seven low-E windows on the south side provide energy savings in the winter by warming their main living area. “It took a while to find heating contractors who could work with a well-insulated house and to implement new ideas, which Webb Plumbing and Heating did nicely,” says Phyllis. “Our main advice is dealing with subcontrac20

tors – the heating, plumbing, and electrical,” explains Phyllis. “Those are the ones that are really important for ICF. You have to make sure you get someone who knows what they’re doing so they don’t oversize the unit.” Since the airtight building envelope of an ICF home reduces heat loss, it has different requirements than traditional buildings. By standard home calculations, the Barters’ home would require two units, but a single two-cycle unit, three zone system has served their needs perfectly. “If it gets really cold outside, it goes to the higher speed, which has not happened yet, taking more voltage,” Mike explains, “but it’s operating less expensively because it operates at the low-speed cycle.” After living in the house for the past year, the Barters have found that it doesn’t require heating or cooling until the late afternoon and turns off by 8 p.m. “It’s a pleasure not hearing the heat pump kicking on and off,” says Mike. HOME SAFETY & SELF-SUFFICIENCY Recent years have seen a rise in tornado destruction in their area. With steel-reinforced ICF walls that are covered


in Hardie Board lap siding, the Barters aren’t worried. The basement also houses a cold storage room designed to double as a storm shelter. It remains a consistent 59 degrees yearround and gives them peace of mind. After completing the house, Mike and Phyllis moved on to designing and building an ICF greenhouse with a homegrown approach to geothermal heating and cooling. The greenhouse, along with the chickens they already keep in a traditional coop, are all part of the Barters’ dream of

self-sufficiency and long-term sustainability. More than a decade after first discovering ICF, Mike and Phyllis have finally created a comfortable, durable, and safe home. Well-insulated walls and renewable energy from their solar panel systems give them the independence and peace of mind they’ve always dreamed of for their retirement years. Now that the house is complete, the Barters are enjoying the mesmerizing mountain views and a reduced cost of living thanks to their Net-Zero Energy home. But it’s a safe bet that future years will find them training others to build ICF homes, a dream that has become their passion. Kelly Stokes is a freelance writer based in Austin,

pcainsights UPDATE ON RESILIENT CONSTRUCTION LEGISLATION On June 4, Congressman Mario DiazBalart (R-FL) introduced H.R. 2241, the Disaster Savings and Resilient Construction Act of 2013, with Congressman Andy Harris (R-MD) serving as an original co-sponsor. The act provides a tax credit to the owners of buildings or homes rebuilt using resilient construction techniques following federal disaster declarations. Similar legislation was introduced in the 112th Congress. PCA continues to engage with a broad coalition to gain support for this effort, in hopes of getting H.R. 2241 passed in the 113th Congress. Not only have the Leading Builders of America endorsed the effort, but also the Property Casualty Insurers Association of America has also recently joined in support of the effort.

The agency also noted that a potential rulemaking is being considered but did not provide details on the impact a rulemaking may have on the pending draft guidance. PCA staff has monitored this draft guidance process since its 2011 comment period and subsequent delivery to OMB. The agency also provided generic updates on the December 2012 PM 2.5 NAAQS final rule state implementation process and the ozone schedule, which is not expected to have proposed ozone NAAQS rule announcement until 2014. CLIMATE CHANGE POLICY On June 25, President Obama announced a new climate change policy that includes a series of executive actions designed to cut carbon pollution in America; prepare the U.S. for the impacts of climate change; and lead international efforts to combat global climate change and prepare for its impacts.

ria, Texas, may prove to be the gateway project for RCC in the booming Eagle Ford Shale region. A June open house at Pioneer Natural Resources, organized by the Cement Council of Texas, attracted 70 attendees representing public agencies, consulting engineers, private facility owners, and contractors. Rollcon LLC, the RCC contractor, showcased the pavement process, from pug mill mixing, to high-density paver placement, to compaction and curing. The Texas legislature recently appropriated $450 million for reconstruction of state and local roads that have been destroyed by oil and gas activity, and local stakeholders are seeking a durable, long-term pavement solution, like RCC. The Pioneer facility is a pipe fabrication/supply yard servicing the Eagle Ford Shale Play in south Texas. The attendees were principally interested in RCC to build similar private facilities, or to remediate state and local roads that have been destroyed by oil and gas activity. In a panel discussion, facility owner Pioneer noted that RCC offered lower initial cost and maintenance than the planned unsurfaced aggregate base for material storage/handling areas, and asphalt pavement for employee parking. The elimination of dust control was a huge motivator, and RCC could also take advantage of local aggregate supplies. The general contractor, Weaver & Jacobs, expressed surprise that construction of the concrete is taking considerably less time than the original pavement choices.

FOUR REASONS YOU REALLY DO NEED A BASEMENT

THE BEAUTY OF BASEMENTS Text by BARRY HERBERT

W

HILE WE GENERALLY THINK OF HOMES WHEN WE DISCUSS BASEMENTS, THE SAME ADVANTAGES AND CONSIDERATIONS CAN BE APPLIED TO OFFICE BUILDINGS, APARTMENTS AND MOST OTHER TYPES OF BUILDINGS. In certain parts of the country basements are typical. In northern states where foundations are required to extend below a predetermined frost line, much of the wall required for a basement is already mandated. The farther south you live, the shallower the frost line is, and so it becomes less economical to build below ground – unless you look at the big picture. In this article I’ll attempt to briefly illustrate three fairly well known advantages of basements, plus one that most people might not consider. 1. Safety from storms. Most of the readers of this magazine either live in a concrete home, would like to live in a concrete home, or have at least considered living in one. A concrete

home, of course, is the ideal protection against storms. Unfortunately most Americans still live in wood frame dwellings. For those families, the thought of having a basement to get into during severe weather, such as a tornado, is a real comfort. Any corner of a concrete basement is much safer than anything upstairs in a wood frame house. A safe room within a basement multiplies that protection many times over. These rooms are often built under the front porch area, which in many cases already has four walls. Too often these areas are merely filled with dirt and capped off with a concrete slab creating an unusable space. A more efficient means of utilizing this area is to place a door opening in the wall separating the porch from the basement and constructing a suspended concrete slab over the porch area. This creates an almost impenetrable safe room for people, documents, and pictures. It also doubles as a great place to store food that needs to be in a cool place. 2. Economical living space. Although a basement foundaSeptember 2013 • Concrete Homes

tion does cost more than a house built on a slab or crawlspace, the additional space gained is difficult to match with any other type of cost/square footage ratio. The same roof that covers the lower level also covers the first and second story of the house. The footprint of the house remains the same whether a basement is included or not so there is no additional lot cost. The extra space can be finished off and used as a family room, a recreation room, an apartment for aging parents or almost grown children, an exercise room or just extra bedrooms. If the entire lower level – or terrace level – is finished off, several or all of the above rooms can be incorporated into the floor plan. It is not necessary to finish the entire lower level immediately. It can instead wait until the need arises or until money is available. 3. Extra Storage. Sometimes you need extra storage in addition to extra livable space. Utilizing the basement or lower level for that storage space is very economical. An added benefit to creating this extra space for storage is that you may actually be able to use your garage for its original purpose. 4. Energy Efficiency. The least recognized reason for a basement is possibly the best one. Mike Hancock of Basement Contractors Inc. based in Edmond, Oklahoma, is a registered mechanical engineer. He has given several seminars at the Concrete Foundation Association’s annual summer meetings regarding concrete homes and the peculiarities of heating and cooling them. In addition to being a registered engineer, Hancock is a poured wall contractor specializing in concrete homes and basements, not only is he considered an expert by his peers, he practices what he preaches. He has constructed several concrete homes and commercial buildings, plus hundreds of basements. “A basement which is sunk down


belowgrade into the ground acts like a big heat sink,” Hancock states. “In order to fully utilize this phenomenon, HVAC systems should be designed to circulate cool air from the basement into the upper floors during the summer months. The circulation of conditioned air helps stabilize the humidity in the basement. During the winter months, the lower level costs little or nothing to heat.” Basements are naturally cooler in the summer and warmer in the winter because of the constant ground temperature. Hancock believes this occurrence should be taken advantage of by circulating cool basement air into the upper floors during warm periods. Then, during winter months, the lower level is heated for practically nothing. In fact many homeowners in the north – where winters are extreme – don’t heat their basements at all, when they use them for storage only. A relatively comfortable temperature is maintained during some of the coldest months because of the warmth emanating from the ground. Boman Kemp, a manufacturer of egress windows and egress wells for the foundation industry has done extensive research into utilizing the constant temperature of the ground to help cool homes. With their Liv-Space™ system they suggest installing the ductwork and the furnace under the basement floor slab to capture even more of the cool ground temperature. The cool air is then circulated to the upper floors by means of vertical ductwork. It should go with out saying that every precaution should be taken to ensure no ground water would leach into the system. You can find out more on the Liv-Space™ design at boman-kemp.com/index.html. When building any structure utilizing this method of heating and cooling, it is important to have someone who understands this process design the HVAC system. In the event that a home is also built of concrete and has increased insulating efficiency, it is necessary to downsize the HVAC

unit. The designer/installer must be knowledgeable of this fact. Whole house ventilation systems are available, and are considered by many to be a good idea for any new construction. In any home or office building, indoor air quality is of upmost importance. Our ancestors didn’t need to worry as much about indoor air quality because air was constantly leaking in and around windows and doors. Most homes and offices built today – especially those utilizing concrete construction – are extremely airtight. While this makes the structure much more energy efficient, it also makes it difficult for the structure to breathe. This article by no means details all of the many advantages of lower level living, but it hopefully will start you thinking more about the advantages of basements. Whenever I drive through a subdivision and see houses being constructed on concrete slabs, I am amazed that people would not recognize the

many benefits of building their home on a basement. Barry Herbert is a

News from the cement and concrete industries

MAKING JOPLIN SCHOOLS SAFER By SHERRY BOYD

The Joplin School district has instituted a wide-reaching program that calls for 14 multi-purpose community safe rooms in schools throughout Joplin. The district developed the approach for improved storm safety with some guidance from FEMA and funding through their Hazard Mitigation Grant Program (HMGP) to offset part of the costs. The program includes concrete safe rooms that double as gymnasiums. Also, a new field house at the football stadium and a band / choir room are being built with reinforced concrete to double as safe rooms. When these reinforced concrete safe rooms are completed students and teachers will have immediate access to shelters strategically placed in schools

throughout the Joplin Schools system, and excess space has been allocated to provide community shelters. “Missouri Governor, Jay Nixon, has been very involved in the rebuilding program, along with Dr. C.J. Huff, the superintendent,” said Mike Johnson, Director of Construction for Joplin Schools. “What we have learned is that traditional construction doesn’t cut it. There is no safe place, unless schools provide specifically designed safe rooms. We learned that safe rooms could be built to serve multiple purposes, such as gymnasiums, auditoriums and other areas that have community uses evenings and weekends.” Johnson continued, “Historical records show the areas more prone to risks, such as Joplin is. It only makes common sense to target

these areas making investments so that parents know their children are safe at school.” He added, “Here in Joplin, residents voted to raise taxes to support the rebuilding of safer schools.” The catalyst for the comprehensive safe room building initiative came from a record setting, multiple-vortex EF5 Tornado that bore down on the southern side of Joplin, Mo., on May 22, 2011. That Sunday evening the damage became catastrophic. The unoccupied Franklin Technology School and Joplin High School were completely destroyed. Later, school officials who reviewed the site as seen from cameras in hallways were aghast to realize the danger existJOPLIN SCHOOLS continued on page 28

ing conditions might have presented to their students if the tornado had hit during school hours. Cameras showed dangerous projectiles hurled by the wind force of over 200 mph, even before the EF5 tornado ultimately caused the walls of hallways to collapse. Up until this review, hallways were considered to be safe shelters for students and staff. There are two types of FEMA funding for safe room construction. Joplin’s new construction includes both the 404 and 406 funding sources for safe rooms. Existing facilities qualify for building additions of community safe rooms under the 404-funding stream. Since safe rooms become dual-purpose, usable space in the building, FEMA funding can be used toward the construction, but not finishes and furnishings. Additionally, this funding requires a 25% match. The Joplin Schools reports that the completed shelters will be covered 50% by FEMA and 50% by the district through school bonds. “Joplin East Middle School and Elementary No.2 are designed as a conjoined building housing approximately 1500 students,” said John Brown, Partner, Hollis + Miller Architects, who leads the project. “Centralized areas are considered best for high wind shelters and ultimately the elementary gymnasium, middle school music room and shared community rooms have been selected to collectively house the student and staff population of both schools. The shelters were partially funded by FEMA with the use of castin-place concrete walls and roofs. They are designed per FEMA 361, which includes provisions for a three-second wind burst of up to 250 MPH.” It is the goal of Joplin Schools to ensure that a 24-hour community safe room is available for every school neighborhood. The planned community safe rooms are being built to hold residents within a five-minute walking distance. The doors can be unlocked when a tor28

nado siren is issued using a reverse 911 calling system. When it is opened to the community, a group of community members who live near the school will be trained to manage the shelter. Joplin Schools are in the midst of an aggressive rebuilding program permitting a program that exceeds minimum building requirements and sets new standards for building safer schools. Two new school complexes will be completed before the end of 2013. Nine other safe room additions are slated at existing schools for completion by May 2014. The new 504,000-square-foot complex that makes up the Franklin Technology School and Joplin High School is due to open in August 2014, and Studies at two historic school buildings are underway to add safe room additions as soon as their specific restrictions can be addressed. “Building codes are intended to keep people and property safe, but they only provide minimum requirements for construction,” says Donn Thompson, the Portland Cement Association’s director of market strategy and positioning. “By using proven concrete technology and building to a higher standard, we can create more resilient, more robust structures that can stand up to strong winds, fires, storm surge and other punishing forces with little or no damage.” Thompson concludes, “Recent, extreme weather events demonstrate that devastation to homes and other buildings has gotten too great to ignore.” CM
