INSIDEthis issue

IntroductionWhen discussing energy performance in buildings, electrical,mechanical and lighting systems are often the first elements that come to mind since they are more closely associated withthe “meter reading.” Building enclosure systems are often overlooked, but in many cases can have a significant contribution in the overall energy consumption of buildings.

Chamberlin Waterproofs The Star

Improving Energy Performance inExisting Buildings

The Ford Center at The Star, Frisco, Texas

Frisco, Texas, now claims one of the most dynamicdevelopment concentrations in America with their“$5 Billion Mile,” a one-mile stretch of real estatedevelopments under construction along the DallasNorth Tollway. The first of these developments isa $1.5 billion complex called The Star, a 91-acrecampus encompassing the Dallas Cowboys WorldHeadquarters, The Ford Center, two parking garagesand two outdoor practice fields.

The Dallas Cowboys World Headquarters is a six-flooroffice building with a two-level parking garage. TheFord Center is a state-of-the-art, 510,000-square-foot

indoor athletic facility containing the Dallas Cowboysindoor practice field, training room, office space andhydrotherapy. Chamberlin worked on both facilitiesand their parking garages installing approximately320,000 square feet of spray-applied air barrier,215,000 square feet of hot fluid-applied waterproofing,200,000 linear feet of sealants and 125,000 squarefeet of sealer. Chamberlin’s scope also includedfirestopping, water repellents, sheet metal flashingand trim, pavers and expansion joints. This massivescope was completed in 16 months with a totalcontract amount of nearly $5,000,000.

The building enclosure contribution tooverall building energy use is a function of theoccupancy, use, size and geographical locationof the building. Building enclosure performanceissues that result in high energy consumptioncan be caused by a variety of factors relatedto both design and installation. These caninclude air leakage, improper or missingthermal barriers, thermal bridging atpenetrations and window openings andinappropriate selection of glazing systems.When reviewing options for improving energyperformance in existing buildings, owners andmanagers should take a holistic approach andconsider the impact of the existing buildingenclosure systems on the overall buildingenergy performance, rather than simplylooking for what may appear to be the mostobvious upgrade for a quick payback.

Assessing Existing Energy Performance Building enclosure systems must be perfectly

installed to perform exactly as designed onpaper, but this is not achievable in practicegiven short construction schedules, costlimitations, inclement weather conditions andother factors. The nature and quality of theinstallation will determine how much these“deviations” affect energy performance. Smallissues such as gaps in cavity insulation maybe insignificant on a whole-building basis,while issues such as poor air seals at windowsystems can have a significant impact onoverall energy consumption. However, evenif enclosure systems are nearly perfectlyinstalled it will still experience performanceissues if they are not properly designed.

Any building energy performance improvementproject should include a study to understandthe overall energy performance of all buildingsystems, including enclosure systems, sothat improvements can target those areas ofhighest potential savings. However, review

Problem Solved During the preconstruction process,Chamberlin noticed a tie-in concernbetween the below-grade waterproofingsystem on The Ford Center’s parkinggarage and the hot fluid-appliedwaterproofing that was to be applied tothe horizontal slab on the plaza above.The below-grade waterproofing to beinstalled was a “peel and stick” materialmade of raw asphalt covered with aplastic facing, to which the hot-appliedwaterproofing would not adhere.over time it would become brittle andbreak away, disconnecting the twowaterproofing systems and allowingwater to infiltrate the parking garage.

Upon discovering that no pre-existingdetail would resolve this problem,Chamberlin suggested a new detail. Tobegin, an additional, sacrificial layer ofthe peel and stick was applied wherethe systems met. The plastic facing onthe top of the additional layer wasthen removed using a roofing torch,revealing the raw asphalt portion ofthe peel and stick waterproofingsystem. Since the hot fluid-appliedwaterproofing system is alsoasphalt-based, they were then able toadhere together completely. Meanwhile,the bottom half of the additional piece ofpeel and stick would continue toadhere to the existing peel and stickwaterproofing installed on the vertical

wall. The two systems weresuccessfully tied together with afull, single layer of peel and stickmembrane left undamaged.

This innovative new detail keeps theparking garage watertight while keepingboth waterproofing manufacturerwarranties in tact. Additionally, it wasthe most cost-effective solution.

Creative DesignThe Ford Center includes a two-storyweight room with a balcony on thesecond level. This balcony wasoriginally scoped for a paver systemsealed with hot fluid-appliedwaterproofing. However, a largeartificial turf area where the players canrun drills for training purposes was lateradded. The new design included paverssurrounding only the perimeter of themock field. The concern was if thepavers weren’t locked in and securedtogether across the entire balcony,the extra load and foot traffic offootball practice would result inpaver movement and trip hazards.

Chamberlin proposed a design thatincorporated the turf field and allowedthe pavers to cover the whole balcony.The pavers underneath the mock fieldwere lowered one inch then infilled withturf, making it level with the with thesurrounding perimeter pavers. Since

of building enclosure systems may not be as simple asreviewing design drawings, maintenance records and/orutility bills. To accurately assess the contribution of theenclosure systems to the overall energy performanceof buildings requires a comprehensive study that mayinclude some or all of the following:

• review of available design and construction documents.

• review of actual utility bills.• review of exploratory openings to verify existing

construction. Unlike systems such as lighting and mechanical where capacities, efficiencies and ratings are easily visible, building enclosure systems depend on a much wider range of factors which cannot be found on a printed label.

• Data logging of existing interior/exterior ambient conditions.

• Air leakage testing of individual enclosure systems and/or whole building air leakage testing.

• Infrared thermography of enclosure systems.• 2-D or 3-D thermal modeling.• Hygrothermal modeling.• Whole building energy modeling.

the pavers were two inches thick, they wereable to be offset by that inch and still be tiedtogether. The paver system was installed ontop of a Tpo roof system since the first storyof the weight room is housed below. Thissystem effectively keeps water out of thebuilding and limits the amount of pavermovement when in use.

Unusual CircumstancesThe south wall of The Ford Center was builtunder a tight schedule. Construction on the38,000-square-foot wall began only threemonths before the building was scheduled toopen, cutting normal production time almost inhalf. And it is no simple wall. The exterior ofthe south wall is comprised of metal panelingdisplaying a 2,270-square-foot video boardabove a protruding glass entryway containingtwelve doors. Chamberlin stepped up tothe plate and completed their scope ofspray-applied air barrier, firestopping andsealants in less than a month, working12-hour days up to seven days a week forthe benefit of the owner and the project.

The plaza in front of the south wall is over theparking garage, so weight restrictions andweight distribution of large equipment had tobe taken into account. In addition, an eyebrowat the top of the wall prevented Chamberlincrew members from being able to access thearea they needed to install the firestoppingand sealants from an aerial boom lift or swingstage. The equipment would raise them

almost 200 feet in the air, but they then had tocrawl on the structure’s steel beams to reachthe installation area. Connecting boards wereinstalled so they could move from beam tobeam. High winds further compounded thisalready challengingworksite.

Chamberlin created asystem to allow the crewmembers to completethis work safely. Twomen worked together,one on the steel beamsabove and one on theequipment below.The crew memberbelow handled cuttingmaterial, loading caulkguns, passing materialsto his partner and other preparation tasks toallow the other crew member to focus solelyon installing the material.

Beam clamps were attached to every steelbeam, to which the crew member installingthe material tied off with dual leg lanyards.With great care and coordination, the crewmember below assisted his partner by firstsecuring one of his lanyards and thenmoving the other lanyard to the next tie-offpoint for him, one at a time, for the lengthof the beam. With this system, every crewmember was securely tied off at all times.

This extremely challenging and unusualinstallation method was not only performedunder extreme time constraints, but performedsafely and successfully.

once the existing performance parametersfor enclosure (and other systems) havebeen determined, a whole building energyanalysis/model can be used to compareimprovements to various building systemswith other existing building systems anddetermine their impacts on overall energy use.Modelers, and owners and building managers,must understand that variables such asoccupant behavior, heating and coolingset-points, utility use, etc., cannot be reliablypredicted. Although predicting actual energyuse with computer models is difficult dueto the wide range of variables involved,predicting relative changes in performanceby improving one or more building systemsis more realistic.

It is important to remember that achievingeven a 100% improvement in the thermalperformance of the building enclosuresystems will provide minimal improvementin a building where the energy use isdominated by other factors such as lighting,ventilation or industrial processes.

Case StudiesWe have witnessed building owners ready tocommit to substantial enclosure upgrades,such as full replacement of window systems,without assessing the actual cause of poorenergy performance. In these cases theremay be little improvement in overall buildingenergy efficiency and decades before theimprovement investment costs are returned.The following case studies are examples ofprojects in which we have investigatedbuilding enclosure systems contributing topoor overall energy performance in buildings.These case studies are examples andinclude important strategies and conceptsin assessing existing performance beforeconsidering repairs or upgrades to existingbuilding systems.

Case Study #1 – High-Rise ResidentialBuilding in New EnglandWe were approached by a building ownerto determine the payback period for a fullwindow replacement project for an existing30+ story high-rise hotel building where themajority of the cladding consists of stripwindows and other fenestration systems.Existing windows included non-thermallybroken aluminum frames with insulatingglazing units (IgUs) without low-e or othercoatings. The owner advised us that thepurpose of the window replacement was notonly to consider energy improvement, but toremediate widespread water leakage andfogging IgU problems.

To understand the existing energyperformance of the building, we developed a“baseline” whole-building energy model usingexisting drawings for general geometry andinterior space layout. Adjacent buildings wereincluded in the model to consider shadingeffects. We calibrated the baseline buildingperformance by adjusting air leakage ratesand other variables such as occupancy ratesin the model to more closely align the baselineperformance with actual utility use data.

With a baseline model complete, we werethen able to adjust the window systemperformance and air leakage rates to assessthe potential performance gain of providingreplacement thermally broken aluminumwindows with low-e coated IgUs. The resultsshowed less than 1% reduction in overallannual energy use with a payback period ofover 100 years. Existing internal buildingloads such as lighting, equipment and wateruse were extremely high compared to theheat gain/loss through the window systems,making improvements to the window systemsless effective on a whole-building basis.

This project is a good example to showeven buildings that are primarily clad withfenestration systems may achieve littleimprovement in energy performance byimplementing a very costly and disruptivewindow replacement project. Upgrades tomechanical, electrical and water systemswould better serve this owner for improvingenergy performance. However, in this casethe model results were helpful to the ownerin that they demonstrated how similarimprovements in energy performance couldbe achieved by purchasing less expensivewindows that also addressed their waterleakage and insulating glass unit problems.

Case Study #2 – Mid-Rise Office Buildingin New EnglandA university client approached us regardinga large, 10-story, over 300,000-square-footfacility that was experiencing high energy useand widespread water leakage in the exteriorwalls. The existing facility was constructedof cast-in-place concrete with thousands ofwindow openings with translucent panels andless than 10% IgUs (the remainder beingmonolithic glazing). Many windows wereexperiencing deteriorating window filmsand approximately 75% experienced waterleakage problems.

Similar to case study #1, we developed awhole-building energy model to performan energy demand analysis. The analysisshowed a comparison of the existing

whole-building energy performance versuschange in heating and cooling demands forvarious building enclosure upgrade options.The various upgrade options included fullreplacement of window systems, addinginsulation to the interior side of opaque wallassemblies, adding roofing insulation by roofreplacement or to the underside of the roofdeck and a combination of each.
