Our thought process has a lot todo with the change we experience.Also, unique emotions tend to guideus on how we will accept, refuse orinitiate change. The path of changemay be denial as we hold on to whatwe know to be true, and then resistchange at all costs. Some experts pre-dict the younger generation is moreadaptable to change as they rely moreon conceptual thinking than us inthe older generations.

Conceptual thinking is focusingmore on the big picture, being a bitmore creative and searching for newsolutions to old problemsthus cre-ating new opportunities and tak-ing advantage of societal changes.Facebook, Twitter and LinkedIn areinventions from these conceptual-type thinkers. They saw an oppor-tunity and thought to themselves,How can I make something hap-pen? How can I take advantage ofnew technology? They often arelabeled as free thinkers by believ-ers; and, as out there by the lin-ear thinkers. The linear think-er relies on a basic step by stepapproach and sees a straight linethrough a series of tried-and-true

steps to solve a problem. The concep-tual thinker works a more complexprocess to reach a goal. Successfullinear thinkers have achieved successby lineal thinking; they know whathas worked, made them successful,and ask themselves, why change?You cant blame themit worked.

Conceptual thinkers bring newideas, they tend to think outside thebox and can come up with alterna-tive ideas that are labeled as great orpossibly dumb.

WHO IS RIGHT?Lineal thinkers are more predictable;they focus on that lineal path, andonly deviate from that path whenforced by circumstances. They tendto be more dogmatic and want tofollow that proven historical path.

In our industry, we have bothtypes of thinkers and they tendto gravitate to a particular side ofour industry. Most contractors arelinear-style thinkers, simply by thenature that they are driven to thatmode of thinking in order to suc-ceed. They bid work and to makemoney they need to be more efficientthan the competition.

They push for lower costs, push theirworkers harder and cut waste to a min-imum. This linear thinkingcoupled

with hard workfunctions quite wellfor contracting. Conceptual thinkersgenerally gravitate toward manufactur-ing or consulting, and some move intomarketing. They tend to create newproducts that solve old problems. Theysee the opportunity to capitalize on asituation, trend or change in law andconceptually come up with an idea.They think in terms of market share,embrace change and often have anequal amount of failures and successes.The contractor cant afford failuresitis not an option. But the successes ofconceptual thinkers re-shape the world;linear thinkers may learn to adapt to itand make it work for them.

Lineal thinkers are not very inter-ested in change and most find it dif-ficult to even sit long enough to listento the conceptual thinkers concepts.Conceptual thinkers tend to look forchange, sometimes even when changeis not needed. Lineal thinkers avoidtaking a risk: the path is clear, the planbasic and the road to success is hardwork, and staying on that course fol-lowing what others have done beforethem. They will just be better at it.

WHICH AM I?Are you trying to figure out whichone you are? Most of us are a bitof both; we all tend to be broughtup with a leaning toward one direc-tion or the other. Both are valuableassets. The trick is to recognize andrespect the traits in each.

As the experts predict, the nextgeneration will be more conceptualin their thinking process. They willwant to know the ultimate goal andbe allowed freedom in reaching thatgoal in their own individual way. Suc-cessful organizations will recognizeconceptual and linear thinkers fortheir value and will prosper or failaccordingly depending on how wellthey manage each.W&C

Change happens. It may be slow and at a glacial pace but

it happens. There are reasons why change occurs and why

it is so difficult and slow to happen. Change occurs in two

ways: It is either forced upon us or we initiate change.

Far away from the hustle andbustle of a big city, Silver CreekResort in Snowshoe, W. Va., has got-ten a new lease on life. The nine-sto-ry high rise building, with 239 con-dominiums, has recently undergonea complete renovation, and this timethey are doing it right, accordingto Sam Collins, who is the generalmanager and acting project manager,as well as being a resident for sixyears at Silver Creek.

Our original cladding was apanelized EIFS and weve had waterleaks since the beginning in 1985but thats because it wasnt installedor maintained correctly, said Col-lins. This time we worked with anarchitect and looked at metal panels,

fiber cement and other claddings,

and selected a 5-inch drainable Sto-Therm Lotusan NExT (EIFS) fromSto Corp. because it was the best fitfor our needs and the best R-value.A 5-inch drainable EIFS providesan approximate R-19 of continuousinsulation, also referred to as CI.

The NExT system includes Sto-Guard, a fluid-applied waterproofingair barrier, and StoLit Lotusan, a fin-ish with a pronounced self-cleaningeffect, and five inches of continuousinsulation. These three componentscreate a high-performing, eye-catch-ing wall cladding system that saves

energy and stays attractive for years.

This Sto reStore project consisted of125,000 square feet of the companyswall cladding.

Snowshoes weather and climatemake for the best snow in the South-east. It also results in some of the mostextreme wind, snow and rain in theSoutheast and prior to the renova-tion, every time a severe storm camethrough Silver Creek, management hadto deal with damaged carpets, replacedrywall, fix popcorn ceilings, and con-tinue to band aid the problem.

Each time we had a storm withany wind-driven rain, we had any-

ages that our maintenance depart-ment had to work numerous hoursto repair, costing us anywhere from$5,000 to $20,000 in repairs eachyear, says Collins.

According to Collins, at the timethe original EIFS was installed therewas no option for substrate protec-tion, air barriers or drainable sys-tems, but that has changed greatlyover the years. Bill Perry, senior proj-ect manager of Pillar Construction,says the key to any cladding projectis to know what you are doing. Thetechnology has vastly improved in 20years, and with the latest and greatestin air barriers and finishes, this wasthe perfect solution for Silver Creek.

Before starting the project, sec-

tions of the building had to be

opened up to identify the existingcondition behind the wall. All of theissues had to be identifiedthe waythe EIFS panels were hung on thebuilding, the window leakage issues,and the imperfect seals - so thatthey could create a solid, water-tight

building in the new cladding.The team, which included Pil-lar Construction Inc. as the generalcontractor, Keast and Hood Co. asprime consultant and structural engi-neer, Williamson & Associates asbuilding envelope consultants, andPeter Fillat Architects, along withSto, all worked together from thebeginning to create a durable, water-tight, and energy efficient building.

We had to remove all of the orig-inal exterior skin including the EIFS,exterior sheathing and wet wall cavi-ty insulation before we could begin,says Perry. The trend now is toinsulate outbound of the exteriorsheathing taking the insulation outof the cavity, and we did just that.

THE BEGINNINGSam Collins and members of theboard of directors at Silver CreekResort knew they had to do some-thing. Their building was leaking, andhad been for more than 25 years, andthe damage to the building was justgoing to escalate. After looking at upto 10 different cladding options, theydecided on using EIFS. They foundtwo companies on the East Coast andinvited them to meet with them.

Pillar Construction was impres-sive and we liked the work theyvedone, says Collins.

According to Perry, they showedthem vivid illustrations of what thebuilding would look like, and whenchosen, they got involved with budget-ing and selection of the system fromthe beginning. After the initial draw-ings, they worked with architect, PeterFillat, who came up with the plans.

We created drawings and workedclosely with Williamson and Associ-ates, says Fillat. It was a big joband a gigantic, interesting building.Nobody wanted to change the archi-tectural faadeits strongandthey wanted to keep it simple.

According to Perry, the options Pil-lar provided, and the solution that theentire team presented, gave the board

clarity and a better understanding of

cialty contractor doing business for

tion project.

what they had and how to solve theproblems to create something very spe-cial. One of the key selling points wasthe air and moisture barrier, which isnow code in most states, says Perry.

Adding a continuous air and mois-ture barrier was crucial, and gavethe building a much truer R-value.The air barrier connected to thewindows to give it a tight seal.

All 740 windows needed to bereplaced. The new windows, whichwere Wojan M950 Series thermalbreak horizontal sliding and fixedwindow assemblies, were also alarge factor in the energy savings.

The previous installation wasrequired to have expansion jointsbetween each panel, but becausewe removed everything down tothe studs we were able to eliminatethe panel to panel joints in the sub-strate, says Brock Osborn, Stosbusiness development manager ofrestoration. This allows the air bar-rier to run continuously between thepanels and allows for less opportuni-ty for water and moisture to get in.

CHALLENGESThe project was done in two phasesover more than two years. The build-ing was occupied during the entiretransition, with full-time residentsand vacationers. This is a large prop-erty and getting all the ownershiptogether to begin the renovation wasthe first challenge, according to Perry.

The next challenge was the climate.Silver Creek is located on the SkiSlopes and sits at 4,200 feet above sealevel and the annual average snow fallis 180 inches. The decision to reno-vate was made in early 2011, howev-er, because of the snowy winters, theyneeded to wait until summer to get

started. The first snow falls in Octo-

ber and can stay as late as April. Soto keep it dry, they first wrapped thebuilding, and then sealed it to keepit enclosed for four to five months ofhard weather. Through this time, thebuilding stayed occupied.

The final challenge was the location.A beautiful and remote resort loca-tion, even the closest Home Depot,according to Perry, was three hoursaway. There is also limited use of cellphones, because of its proximity to theNational Radio Astronomy located innearby Greenbank, W. Va. The crew,which was up to 60 people at any onetime, committed two to three monthsat a time, and stayed on the property.

We made site visits to the remotebuilding location on almost a weeklybasis, says Craig Swift of Keast andHood, the structural engineeringfirm on the project whose main rolewas repairing the metal stud back-ing. Much of the metal stud claddingwall system had been significantlycorroded and deteriorated, thoughthe primary structural system wasin fairly good shape. The key struc-tural challenge was to design repairsand replacement of the metal studwalls without requiring removal ofinterior finishes or access from theinterior. Ultimately, a team effortfrom all parties overcame the chal-lenges to get to a great end result.

TESTING: ONE, TWO, THREEAccording to Fillat, there were sever-al water tests and inspections alongthe way, including after the windowswere installed.

Scott Johnson, an inspector withWilliamson & Associates, cameout during phase one with windowwater testing and came back duringphase two to test the windows and

claddings related to the openings.

The building tested out fine,says Johnson. There was a majorstorm during the final phase of

construction, with 85 mph windsand hard rain, and there were noleaks. We attribute this to the

EIFS and windows, and of course,the installation.

Johnson and his team performedthe ASTM E1105, a uniformed staticpressure test to evaluate water infil-tration performance, capabilities ofwindows and related construction onthe building. Testing was performed atthe most stringent requirements. Theytested each assembly for 15 minutes.

The end result is a beautiful, drybuilding, changed from white toearth tones. The new main creamcolor, with a separate forest greencolor inset, gives the building a dis-tinct profile and more depth, accord-ing to Fillat. This is the first time Fil-lat had ever worked with a drainableEIFS cladding and he feels its a greatsolution to a long-standing problem.

An interesting addition to theresort is that it now has the logo andsignage built into the building, whichthey have never had before. On theend of one of the wings of the build-ing are two foot high letters statingSilver Creek Lodge, and on the frontof the building Silver Creeks logo isadded, which includes the name anda skier with swoops being cut intothe building. The front logo lettersare up to 8 feet tall.

And not only does it look good,people are noticing drastic changes intheir utility billswith a savings nowof 20 to 50 percent, says Collins.Its quieter, too. Being a ski resortthe noise reduction from the outsidehas been a big improvement since inthe winter time you have ski guns andgrooming machines running all of thetime. And another benefit is that frominside my residence I can no longerhear the wind blowing or have snowin my living room each morning whenI wake up.W&C

easide, Fla., is located along thestates Panhandle Coast midway

between Ft. Walton Beach and Pan-ama City. The community is oftenreferred to as an example of newurbanism, a design movement that pro-motes walkable neighborhoods, easierpedestrian accessibility and greaterintegration of public transportation.

Composed of different housingstyles, boutiques, services, restau-rants and offering cultural eventsthroughout the year, the area hasmade a significant impact on urbanplanning and offers homeowners a

unique residential experience.

CHALLENGING WEATHER EXTREMESGiven the geography, structures inSeaside are often subject to weath-er extremeshigh humidity, heavydownpours, and tropical, wind-driven rain spawned from the Gulfof Mexico.

A new three-story res idencefacing the Gulf, as well as Sea-

sides main thoroughfare proves

no exception. The Arkon Group,the site contractor, had seen whattrapped moisture could do tohomes constructed in the area overthe past 20 years.

So that the bui lding wouldreceive maximum protection andremain problem-free, Arkon want-ed a system that was superior in

quality to traditional house wraps

or felt, that was easy to install and

would adhere tightly to preparedconstruction substrates. While theresidences first floor was placedusing CMU, the second and thirdf loor exter ior wal ls were con-structed with plywood sheathing.Both of these material surfacesrequired durable moisture protec-tion and strict air leakage controlto ensure the long-term durabilityof the building.

AMAZING GRACETo restrict moisture from infil-trating the walls of the residencesupper stories, the Arkon Groupconvinced the project architectand residence owner to choose avapor permeable air barrier mem-brane made up of a breathablecarrier film backed with a special-ly formulated adhesive. Designedfor use with different types of sub-strates, Perm-A-Barrier VPS per-mits water vapor, which normallywould be trapped inside the ply-wood sheathing walls, to escapeallowing them to remain dry. Itresists hydrostatic water pressureand keeps homes dry even whendownpours and stormy, wind driv-en conditions invade.

As the product is fully-adhered, itcan better protect the home againstwater and air leakage when com-pared to building wrap or felt paper.It also held up very well after beingexposed to UV rays for the fivemonths of construction.

The product eliminates the needfor mechanical fasteners too, sooverall, installation was easier andrelatively problem-free. To protectthe CMUs at the ground level sec-tion of the home, Arkon installedPerm-A-Barrier VP, a fluid-appliedmembrane that creates a solid barri-er against air infiltration and energyloss, minimizing the walls conden-sation problems.

Arkon also installed aluminumflashing to seal detail areas and pro-vide a continuous barrier against air

and moisture penetration.W&C

These mandates will change theway construction professionals thinkabout energy-efficient construction,specifically requiring specifiers toconsider strategies to minimize ener-gy consumption.

THE PROBLEMExterior walls are most commonlybuilt using stud framing with someform of cavity insulation located

between the studs. This method

separates the insulation into non-continuous pockets and allows ener-gy to transfer between the interiorand exterior of the buildinga phe-nomenon known as thermal bridg-ingwhich significantly reducesthe energy efficiency of the wall.

Traditional cavity-insulated wallsalso suffer from air leakage, whichoccurs at joints, gaps and penetra-tions. The resulting airflow into or

out of the building affects energy

efficiency, indoor air quality, andheating, ventilating and air condi-tioning (HVAC) costs. Further, cav-ity insulation gets dirty and canabsorb and retain moisture, whichcan lead to the premature degrada-tion of the studs, sheathing and dry-wall exposed to the cavity.

R-Value is a number used toexpress a materials thermal efficien-cy and the higher the number, thebetter. However, this can be mis-leading because it only takes intoaccount the insulating value of thematerial itself, and not the full wallassembly. As described earlier, atypical framed wall can be compro-mised due to thermal bridging andair leakagewhich can decreasethe R-value of the overall wall by asmuch as 50 percent or more in steel-framed walls and 24 percent or more

in wood framing.

UP-TO-CODE

PERFORMANCE

Energy-related changes are coming for new commercial

buildings. Is the wall and ceiling industry ready?

By Bob Dazel, AIA, LEED Green Associate

Changes are fast approaching for the building industry. TheU.S. Department of Energy (DOE) claims that buildingsaccount for 39 percent of total energy use and 38 percent of total

carbon dioxide emissions in America. The desire to reduce both

is leading to tighter government regulations on new construction,

requiring states to adopt up-to-date energy-related building codes

that will improve the performance of new commercial buildings.



Adding thicker cavity insulationdoes little when trying to improvethe thermal efficiency of the wallbecause it does not mitigate thermalbridging or air leakage.

THE CHANGEIn an effort to combat the increas-ing demands on energy, the DOE hasmandated that by October 18, 2013,all states must adopt a commercialbuilding energy code that meets orexceeds ASHRAE Standard 90.1-2010. The updated standard will trig-ger a substantial change to the designof wall assemblies. ASHRAE 90.1-2010, which has been adopted by thenew 2012 International Energy Con-servation Code, increases the require-ment for continuous insulation formost commercial wall assemblies innearly all climate zones.

Typically revised every three years,the IECC is part of the InternationalBuilding Code and is the governingcommercial code section for build-ing design and material requirementsrelated to energy efficiency. It dividesthe U.S. into eight climate zones,each with specific requirements forthe type, placement and amount ofinsulating materialsboth cavityand continuousin the wall assem-bly. Several versions of the IECC arecurrently in effect across the coun-try, making it vital for architects andother construction professionals to beaware of which version is adopted bythe state or local jurisdiction in whichtheir project is located.

Each latest version of ASHRAE90.1 and IECC adoption have

increased the amount of continuous

insulation required in commercialbuildings, and the current standard(2010) prescribes the use of continu-ous insulation in nearly 90 percent ofthe U.S. There is no doubt that futurecodes will be even more stringentwhen pertaining to energy efficiency.

The latest of these is ASHRAEStandard 189.1: Standard forthe Design of High PerformanceGreen Buildings. This standardsrequirement for continuous insula-tion exceeds the 90.1 Standard byincreasing the requirement for CIto all climate zones and in greaterthicknesses than previously required.

THE SOLUTIONExterior continuous insulation andan air- and water-resistive barrierare the most effective way to meetthe new code requirements by elimi-nating thermal bridging and air leak-age issues associated with traditionalstud framing and cavity insulation.Placed on the exterior of a build-ing structure, continuous insula-tion eliminates the thermal bridgingeffect caused by stud framing andcan translate into a 20 to 30 percentreduction in annual energy costs.

EIFS is not a new or unproventechnology; the system was intro-duced more than 40 years ago to theU.S. construction market and is inplace today on more than a millionstructures. Engineered to integratethe use of an air barrier and con-tinuous insulation, todays EIFS pro-vide a design-flexible, cost-effective,code-compliant single-source solu-tion to todays demand for energy-

efficient, high-performing walls.

EIFS meet the need for continu-ous insulation and offer uniquedesign flexibility due to the abilityto shape that insulation easily into3D designs. Diverse finish optionsare available to achieve a varietyof architectural styles. In addition,one of the most attractive propertiesof EIFS is their light weight. Thesecombine to make EIFS a superiorchoice when compared to other clad-dings. For example, Dryvits Out-sulation systems weigh just 1 to 2pounds per square foot, comparedto the average clay brick weight of40 to 50 pounds per square foot.This translates into a reduction ofbuilding structure cost, materialtransportation and a shortened con-struction cycle. Outsulation providesintegrated continuous insulation, anair/water-resistive barrier and singlesource wall assembly warranty, all ofwhich traditional brick does not.

As October 18, 2013, grows clos-er, the building industry will experi-ence increased awareness of EIFS asa solution to continuous insulation,thermal bridging and therefore, codecompliancy. The trend toward ener-gy efficiency in the U.S. is certain toprogress, and sustainable initiativessuch as building a tighter envelopewill continue to be reinforced as pri-mary focuses in the industry.W&C

The construction industry is being stretched

to evolve in a harder-than-ever market-

place and mobile technology is making

it easier by reaching wall and ceiling contractors

with construction apps.

iPads, iPhones and other smart phones should all

be considered irreplaceable resources on the job site

nowadays with the help of downloadable applications

that organize and deliver information quicker thanever. What makes them better than a laptop is their

level of portability and the range of apps available for

your use. The evolution of contractors utilizing smart

phones to their fullest potential seems to go hand-in-

hand with BIM being accepted by contractors.

Heres an introduction to some apps you should

download to lighten up your tool bag and get the

job done faster, whether youre a beginner who

just got a smar t phone or you already access

BIM data on your iPad. These options range in

price and function but your best bet is to begin

by downloading a free option, understand itsfunctionality, and then pin-point which apps will

work best for you by visiting Apples App store or

Androids Google Play websites.

If youre trying to find an edge against the competition,

a simple solution is to start using apps on your

smart phone or iPad while on the job site.

Marc Rutenberg Homes is striv-ing to create a net-zero energypath of the future. The companysmost recent projects, the Zero Ener-gy America homes, are the fruitsof this labor. In every aspect, thesehomes are designed to exceed thehighest green building standards,providing the healthier, cost-effectiveand sustainable alternative in homedesign and construction.

The first completed homes, andthose still under construction, arescattered throughout Floridaeachdiffering in personal design preferencebut maintaining the exact same valueof selecting extremely sustainable con-struction options. Ashley Rutenberg,LEED AP Homes, the Zero EnergyAmerica Homes project coordina-tor, was also the internal green build-ing consultant. She says there are twodifferent generations of design in thefour Zero Energy America homes.

The first two of the net-zero ZEA

homes were completed in September2012. ZEA 3 was completed nearthe end of 2012, while ZEA 4, theupcoming second-generation home ofZero Energy America, is expected tobe completed in May 2013.

The first generation maintainedthe Florida-Mediterranean style thatis so dominant in the local market,with stucco walls, barrel-tile roofs,and a transitional interior, Ash-ley Rutenberg says. The upcomingsecond-generation home is pushingthe envelope of the local market inFlorida with a more contemporarystyle of architecture but still main-taining a warm, organic and softpalate of materials so that it standsas a comfortable and inviting home.

The goal in the design change from

the first home to the second was tobring newer, fresh ideas, conceptsand living spaces.

INTERIOR CHOICESFrom the interior design choices ofthe low-VOC paint in the bedrooms,the ethanol burning fireplace, andthe roof pavers to the power gen-eration of the building envelope, the4,500-square-foot plus ZEA homeswere designed to incorporate everyavailable alternative to become anexample for future net-zero energyhomes down to the very last detail.In these homes specifically, we usedIcynene spray foam insulation at thetop of the attic, which allows ourHVAC equipments and ducts to be

creating a super-heated attic, saysRutenberg. Think: Why build anoven and then try to cool it whenyou could just cool against the out-side air temperature? We used eitherHebel AAC walls, which are con-crete blocks with high thermal per-formance in and of themselves, orDow XPS insulation.

Dow played its biggest role inthe fourth ZEA home still in theworks. For the Breakwater Mod-el at Champions Club, engineershelped us to design a wall systemthat matches Aerated AutoclavedConcrete in thermal performance(R-value) but without the signifi-cantly higher material cost of AAC.We designed the wall with 2 inch-es of Dow Extruded Polystyrene(XPS) insulationwhere typically3/4 inches would have been usedand a 2-inch chase wall so that theinsulation does not have to be con-

tinually broken by all of the elec-

EE



tric wires, plumbing lines, HVAClines, A/V wires and other MEPcomponents that go in the wal ls of ahome, says Rutenberg.

For power generation of the net-zero energy home, the Rutenbergteam used LG Solar Panels, whichhave supplied more than 100 percentof the electricity needed to powerthe homes so far. Because Ruten-berg used optimized scroll or rota-ry compressors, specially designedheat exchangers and inverter tech-nology, VRF systems from LG werealso used for the home for minimiz-ing energy use to levels unattainablethrough traditional HVAC systems.Kevin McNamara, vice president of

LG, says in the ZEA home, the LG

VRF systems had small ductworkthat increased attic storage spaceand a quiet operation, not to men-tion a cooling-load of nearly ninenominal tons.

Despite the ZEA homes empha-sis on certain sustainable aspects,such as daylighting, ventilation andbuilding insulation, dont call theydont meet the definition for Pas-sive House. A Passive House doesnot necessarily use net-zero energy,and indeed, it would be exceeding-ly difficult to make every aspectof a home passivefor example,refrigerators and other appliances,heated water, lighting for nighttimeand heating on the coldest days are

things that a 100 percent passive

home could not accommodate,says Rutenberg.

The ZEA homes are regardedmore so as a net-zero home becausethe homes were specifically designedfirst to reduce the amount of energythey use through a combination of

strategies. These strategies includea passive design, but also includeaspects like Energy Star appliances,LED lighting and solar water heat-ing. Then, renewable energy sourc-es, such as solar, wind, and tidalfor example, are used to supply thehome with electricity in place of thepower grid or generator fuel.

NET-ZERO STRATEGIESThe key components of a net-zerohome are used as renewable energysourcethe envelope, HVAC andventilation, and lighting and appli-ances. A net-zero home requiresa tight envelope, including thevinyl, insulated windows with low-E coating, insulation and air pen-etration barriers. The placementof the attic insulation is hugelyimportant in a warm-climate home.Correct placement of the insulationat the rooflinenot at the bottomof the attic by the truss chordsprevents having to cool the houseagainst a superheated (140 degreesFahrenheit) attic, and increase boththe R-value of the insulation andprevent air infiltration by eithersealing or using a combinationproduct like spray-foam insulationthat both insulates and seals theindoor air space from the outside,says Rutenberg.

Increasing the R-value of the wallsystem, as well as designing a morecontinuous insulation blanket thatisnt broken at every 18-inches or2 feet near studs, is another impor-tant feature in net-zero homes.Accurate third-party load calcu-lations for correct sizing of theHVAC system is hugely important,as well as then specifying highlyefficient HVAC equipmentsuchas a variable refrigerant system fol-lowed by high SEER-rated conven-tional equipment.

THE FUTURE IS ZEROAt the grand opening of the Cast-away Model III in November

2012, we announced our plans

HOME FREE



for the Zero Energy America Vil-lage, which will be our first com-munity of net-zero homes in a1,600- to 2,300-square-foot rangewith pricing starting at $250,000,says Rutenberg. In these homes, agreater proportion of the sustain-

able focus will be directed towardenergy specifically, though still witha consideration for more sustainablechoices in all areas of constructionand additional customer optionsthat will allow those who desire itto build a mondo-beyondo greenhome as we have done with the firstZero Energy America homes.

In regard to the notion that sus-tainability goes hand-in-hand withconserving energy and resources,addressing questions about the sizeof the net-zero home is somethingthe Rutenberg team has been learn-ing to excel at. This is our favor-ite [topic], because we feel its oneof the most important to address,Rutenberg says. There will be

many schools of thought and anglesof approach to reducing our carbonfootprint. Some people will be will-ing to change themselves and theirown habits, and others simply willnot; you cant always change peo-ple. We praise those who are will-

ing to go the extra mile and changetheir own habits, but we also want-ed to offer a way for people to liveas they always have and still have anet-zero home with no carbon foot-print. This is why we built homes

that fit beautifully amongst theirneighbors in a luxury communityand have no additional demands onthe homeowners that live in them.As long as the market for big, beau-tiful, luxury homes is so high indemand, we will find the way to

make them big, beautiful, luxuriousand green.W&C

of power that is safely available tous for our discretionary use. Itsreally a pretty cool thing when youthink of the convenience of using agiven device by just plugging it intoa receptacle. Our ever increasingdemand for this convenience is put-ting a strain on the cost of makingand delivering the energy. In fact, thecost of energy has hit a tipping point.

We have burned coal, dammed uprivers, used nuclear technology, andharvested the wind and sunallto make available power. But whatwe really havent done is slowed thedemand. The buildings we inhabitconsume 40 percent of all the pow-er produced. Of that, 40 percentis used to heat and cool our build-ings. So, if you havent been asleepor in a cave for the past five years,you already know that the buildingindustry and its building codes arechanging to address this very issue.Now, buildings must meet mini-mum energy efficiency requirementsand these requirements will becomemore stringent in the years to come.

Its a fact: we are building differ-

ently and will continue to do so inthe future.

I know youre thinking oldnews, Albert but wait, theresmore. In order to meet these newcurrent energy efficiency require-ments, our claddings must use con-tinuous insulation.

ASHRAE 90.12010 defines CIas, Insulation that is continuousacross all structural members with-out thermal bridges other than fas-teners and service openings. It isinstalled on the interior or exterioror is integral to any opaque surfaceof the building envelope. So, forall climate zones in the U.S., except1 and 2, cavity insulation alonewill not meet the energy efficiencyrequirements. Consider an assem-bled wall unit. (See illustration). Theframing members (studs) accountfor approximately 25 percent of thewall assembly. Insulation is placedbetween the members in the cavity,as a means to insulate our interiorenvironment. These members actu-ally act as thermal bridges that allow

for the transference (I like to think

of it as a secret passage way) of heatand cold, known as thermal bridg-ing. So, the money spent to heat

and cool our buildings can escapethrough these thermal bridges, thus,further increasing our demand andcost for energy.

RE-INTRODUCING EIFSIn the past, stucco has been appliedover CI and has performed verywell. Ill talk in detail about that inthe next column. This column willillustrate the high CI performanceof my other subject matter: A longestablished, fully tested claddingcalled exterior insulation and finishsystem. EIFS is truly, by definition, acontinuous exterior insulation clad-ding. It is a system based on continu-ous insulation and achieved by beingadhesively applied to an approvedsubstrate. There are some EIF sys-tems that are mechanically attachedbut they are an exception.

By system, I mean that thereare no interchangeable pieces andparts or different combinations ofthings to achieve a CI cladding.The system components are a cho-reographed combination of perfor-mance products from a single sourcemanufacturer. These EIF systemscan be applied to new construction,as well as be applied over existingcladdings. EIFS were created as a CIcladding and were the first kids onthe block to provide CI.

EIFS came to the U.S. in the late-60s and gained popularity duringthe energy crisis of the 1970s. Theflagship EIF system was known asa barrier system with the basecoatand mesh layer being the weatherbarrier. Fast forward to our currentconstruction times and EIFS is nowapplied in most cases with a second-ary barrier, and this is where wewill start.

The s econdary bar r i e r s o f an EIF system are monolithic inthat they are a liquid, applied byroller, spray or trowel to a givensubstrate. This continuous barri-er extends into the fenestrationstoo. So right off the get-go EIFS

provides a monolithic (continuous)

secondary barrier. These secondarybarriers all provide moisture pro-tection for the substrate, preventair infiltration, and are also avail-able as either vapor permeable oras a vapor barrier. The vapor bar-rier versions may be beneficial incolder climates that might requireit. Most EIFS manufacturers pro-vide both versions.

WHAT MAKES UP AN EIF SYSTEMSo there are the suspenders, letslook at the belt. The rest of thesystem: foam, basecoat, mesh andfinish, a complete barrier system,doubles the protection of the build-ing against moisture intrusion. Themost widely used foam, expandedpolystyrene, is applied to the sec-ondary barrier in a running bondpattern and because it is adhered,there are no penetrations of the sec-ondary barrier. The entire perim-eter of each sheet is butted tightlyagainst the adjacent sheet forminga continuous insulation layer. TheEPS foam is made of fused polysty-rene beads which trap air betweeneach bead, offering a superior insu-lation. Since there is no edible foodsource in foam, mold will not growwithin it.

Because foam is applied to theexterior of the wall assembly, theR-value provided by the foam com-

ponent is a true value, no loss of

heat or cold via thermal bridging.By sheer nature of the makeup ofEPS foam, thermal movement isabsorbed within the foam itselfminimizing the chances of crack-ing in the lamina due to thermalexpansion and contraction. Someof the newer EIF systems now areusing extruded expanded polysty-rene (XPS) which carries a higherR-value than EPS does. XPS or EPSfunction similarly as a continuousinsulation layer. As good as theyare at insulating; neither should berun below grade or used as a roof-ing product (applied horizontally inwidths larger than 18 inches) as thismay compromise their integrity.

BASECOAT AND MESH LAYERThe real workhorse of an EIF systemis the basecoat and mesh layer. Thisis the first line of barrier defenseto fighting moisture intrusion. Thislayer must cover 100 percent of anyexposed foam to protect the insula-tion against the environment andto contain foam in fire situations.This layer, like the two under it, isalso monolithic, and continuous. Itis a simple component functioningin a complex way, fighting mois-ture, fending off UV degradation,and moving with the foam duringthe daily dance known as thermalexpansion and contraction, without

becoming compromised.

FINISH LAYERThe final component is the finish. Yes,this layer helps to shed surface waterbut primarily it is there to look awe-some. By shedding surface water thefinish helps to keep the cementitiousbasecoat from efflorescing. And likethe layers below it, it is a continuouslayer of protection. The EIFS finishesare made from high quality acrylicsand can last for many years maintain-ing a newly applied appearance.

There are many new assembliesutilizing CI that all contain varyingdegrees of complexity. The reality isthat any common cladding can beapplied over a CI layer. Many timesthough, figuring out how to properlyterminate, or integrate various com-ponentsor making sure that allof the parts and pieces fit and worktogether, can have a contractor ordesigner pulling their hair out. EIFShas been present for many years andmight even be thought of as a com-mon item, one that everyone knowsis there, but lacks a new complex-ity appeal. However, when onedissects continuous insulation anddefines the intent and performanceof a CI cladding, EIFS falls in as thetrue definition of CI.W&C

GREENBY CHRIS DIXON

how many miles to the gallon a cargets based on color. It is impossibleto do in any really meaningful way.There is so much more that needs tobe considered to really know whatproduct or material is less harm-ful to the environment that another.Energy used for extraction of rawingredients, manufacturing andtransport; in-service life expectancy;maintenance requirements; etc.

The latest and greatest draft ver-sion of LEED has been strugglingmightily with this in moving towarda more comprehensive appraisal ofthe Materials and Resources cred-its, the sixth public comment periodhaving just concluded. Although theUSGBC insists that this will be thelast public comment period beforev4 goes to ballot, public commentswould seem to indicate otherwise.Here is a small example of some ofthe most recent comments: The language relating to valua-tion factor is very confusing.

MR credits need to be radicallysimplified.

We have been reaching outto members of the LEED prac-titioner community to get theirthoughts on these credits. Theconsensus is that the way thecredits are written is overwhelm-ingly too complex.

there are inconsistencies with-in the reporting requirements,which will create frustration andconfusion for all involvedproj-ect teams, manufacturers, LEED

Reviewers, GBCI, etc.

the complexity is truly a deal-breaker for me. As a practitionerand as a state employee involvedin policy discussions, simplicity iskey - what do we want to achieveand whats the simplest manner inwhich to get there? This confusionand complexity doesnt make thiscredit more likeable or useable

Despite the issues highlighted above,the possibility that LEED will revert toa single-attribute-based materials creditis highly unlikely. LEED will eventu-ally get something finalized in the newrating system, and it will look very dif-ferent from what it does now. One ofthe most prominent and recurring fea-tures that is likely to survive the publiccomments, is the requirement for Envi-ronmental Product Declarations.

CREDIBLE THIRD PARTYASSEMENT FOR PRODUCTSThere has been some recent effortundertaken in the industry to pro-vide EPDs to the design and con-struction community. I discoveredone while reviewing a product datasheet for resilient flooring products,a third party sustainable certifica-tion based on NSF/ANSI 332 Sus-tainability Assessment Standard forResilient Floor Coverings. Prior toseeing this listed in the data sheets,I was unaware of the organizationNSF International and also unawarethat it had developed an ANSI stan-dard for the sustainability of resil-ient flooring. After a little digging, I

learned that NSF International is an

independent global organization thatwrites standards, tests and certifiesproducts for the commercial flooring,

construction, food, water and con-sumer goods industries. In additionto its resilient flooring standard, NSFhas developed more than 50 ANSIstandards, among them standards forsustainable carpet, wallcovering, fur-niture and single ply roofing.

The NSF/ANSI 332 uses a point-based system in which manufacturersachieve one of four levels of certifica-tionconformant, silver, gold or plat-inum. The language in the standardis straightforward, clear, reasonableand understandablea testament tothe rigorous process ANSI requires indeveloping any standard that bears itsname. The consensus process used todevelop the standard was built uponscientific principles, including the ISO14000 series standards on Life CycleAssessment and feedback. Productsare evaluated against the standardusing five key criteria: Product design

Product manufacturing Long-term value, Corporate governance Innovation

The criteria are incredibly compre-hensive, and include prerequisitesand point categories that includeLife Cycle Assessment, minimiza-tion of chemicals of concern, green-house gas reduction, durability andemployee injury rate, to name just afew. In total, 100 points are avail-able across eleven prerequisites and47 point-earning categories.

NSF/ANSI 332:DIGGING A LITTLE DEEPER

Jane Wilson, director of standards,NSF International, states that Certi-fication to NSF/ANSI 332 offers buy-ers of resilient flooring the highestlevel of confidence and credibility in amarket that is awash in green claims.I was able to download resilient floor-ing products certified by NSF to thisstandard by going to the NSF web-site and searching for resilient floor-ing products. The certificates for the

products I found contain only the

basic informationthe manufacturer, product, certifica-tion number and certification level. This level of reporting,however, does not provide information as to what points

were achieved and in what assessment categories.The points that a manufacturer elects to pursue inobtaining certification are optional and prerogative. Fora design professional wanting to compare one productagainst another, this information is critical. So, I sent anemail to NSF to find out how to get the full certificationdocument. The response was that this information isnot available through NSF and that I should contact themanufacturer. And so I did.

The manufacturer responded that this was informationI should ask NSF about. I explained that NSF told me thesame thing and it went up the ladder a bit with the manu-facturer. I then received information from the manufac-turer giving me only the percentages of points accumulat-ed across the five categories, nothing else. I tried anothermanufacturer that has resilient products certified to thestandardnot by NSF but UL Environment. I got nearlythe exact same run aroundboth from the manufacturerand from UL Environment.

Withholding information smacks of something far lessthan the whole point of an independent, third-party certi-fication of a product using a consensus-based ANSI stan-dard. A careful reading of the standard reveals severalpoints that look very much like business as usualthingslike recycled content in the product packaging, reportingemployee turnover rate, and profitability (gimme points).What I am interested in knowing (and where LEED and therest of the world is headed) are the other point categoriesin the standard, such as the reporting and elimination ofchemicals of concern, Life Cycle Assessment, and green-house gas reductions. Without this, the certification itselftells very little about a products true greenness.

CONCLUSIONThe introduction of independent, third-party certifiedEPDs into the market is a beautiful thing. Certificationsbased on truly consensus-based processes and proce-dures under the guiding principles of organizations suchas ANSI and ISO. But be warned: That Gold NSF/ANSI332 Certified product doesnt necessarily mean that it hasfewer chemicals of concern, lower indoor carcinogenicVOC emissions, or more recycled content than a productwith a Conformant certificationor no certification. Tomake everybody happy and to continue pushing the enve-lope, 100 percent transparency is required.

The good news is that we are getting there very quicklyand organizations like NSF, with the development ofrobust sustainable product ANSI standards, are helpingthe effort tremendously.W&C
