The High Performance RenovationTremco Incorporated is partof RPM International Inc.; thisflagship project is the result ofthe integration of multiple RPMproducts, systems and services thatserve the worldwide constructionand maintenance and repairindustries. By transforming theTremco headquarters building intoOF THE TREMCO INCORPORATEDHEADQUARTERS BUILDING MAKESA BOLD STATEMENT ABOUT OURCAPABILITY AND COMMITMENT TOGLOBAL SUSTAINABILITY.The ChallengeAIR LEAKAGE2WINDOWSROOFSFAÇADEa sustainable showcase, we arebringing home our commitmentto helping customers developand maintain sustainable, highperformance buildings that areenergy efficient, have limitedenvironmental impact andoperate with the lowest possiblelife-cycle costs.Like many circa 1970 buildings, Tremco’s headquarters building wasunder-performing. The building was extremely energy inefficient witha dismal ENERGY STAR rating of 11 and energy costs exceeding 4.75/square foot, twice the industry average. It was often uncomfortableto work in, and repair and maintenance costs on the three-story,46,200 square foot facility were escalating. Faced with the followingchallenges, the status quo made for an unsustainable, costlyapproach to facility management.ENTRANCESHVACBUILDINGCONTROLSWATER USE
The Solution:Whole Building Retrofit for High PerformanceFACED WITH THE SIGNIFICANT CHALLENGES OF THIS UNDER-PERFORMINGBUILDING, THE CHOICE BECAME APPARENT: RENOVATE OR MOVE.Tremco, which is committedto being a global leader insustainable development, tookthe opportunity to lead byexample and demonstrate howaged buildings can be convertedinto sustainable, energyefficient facilities. The Tremcoheadquarters was slated for amulti-million dollar, foundationto-roof retrofit featuring anintegration of solutions frommultiple RPM companies.The goals of the retrofit alignedwith Tremco’s broader vision forsustainability: reduce energyconsumption and generate onsite renewable energy; capturestormwater and improve waterconservation; minimize the amountof waste going to landfills; reduceoperating costs; improve employeecomfort; and protect the naturalAIR LEAKAGE – Gaps, cracks and holes inthe building envelope (including windowswith degraded gaskets, doors with failedweatherstripping, and gaps within roof walls)created uncontrollable heat loss and gainwhich compromised the HVAC system as wellas employee comfort, and fueled excessiveenergy costs.WINDOWS – Inefficient single-pane, clear glasswindows with non-thermal aluminum framesand degraded gaskets needed replacement.ROOFS – All roof areas had degraded to thepoint of needing replacement.FAÇADE –Cracks and fissures in the slateexterior allowed water to infiltrate the building.environment by reducing carbonoutput. The project was set withthe ambitious goal of achievingLEED Gold certification, and aneven more ambitious five monthconstruction schedule.ENTRANCES – The lack of a vestibule atthe employee entrance allowed outside airto enter conditioned spaces. Also, the frontentrance was not ADA compliant (nor were anyrestrooms).HVAC – Outdated cooling and heatingsystems, which featured a constant flow mixof heated and cooled air, were extremelyinefficient.BUILDING CONTROLS – Constant speed/constant flow controls wasted energy and werenot integrated into the cooling, heating or airhandling controls.WATER USE – Dated plumbing fixturesprevented the most efficient use of water.3

Surmounting ConstructionChallengesRenovating While Building Is OccupiedA top priority during the renovation was that businessoperations not be interrupted as the occupied buildingunderwent its roof to foundation overhaul. A majorchallenge was maintaining comfort for employees whileinstalling the new HVAC system. As the renovation tookplace largely over the summer, maintaining a comfortablework environment was essential. “We spent a lot of time inthe design phase creating a plan to maintain the old systemas the new system was built in the same space,” explainedCraig Nelson, Vice President of Construction Operations forWTI. “The old system was disassembled and removed whilethe new, state-of-the-art chiller system was installed over aholiday weekend, in a matter of three days.”Nelson also noted that while the HVAC reconstruction tookplace in the mechanical room, which is adjacent to thevegetated roof, the vegetated roof was installed at the sametime. A carefully orchestrated plan allowed for both plantsand HVAC components to be installed concurrently.Relocating EmployeesTo minimize the impact on people’s jobs, Tremco temporarilymoved the WTI and Tremco Roofing Customer Servicegroups to a nearby rented facility. This freed up the secondfloor, where interior reconstruction began. Once upgradesthere were complete, employees from the third floor weremoved to the second so that their floor could be renovated,followed finally by employees from the first floor. Each floorwas temporarily moved for about six weeks.The IT and Facilities Departments carefully planned andorchestrated both the offsite and internal moves andmaintained connectivity to IT systems. The moves wereconducted over weekends to make the transitions asseamless as possible. An added bonus of using an offsitefacility was that it reduced the number of cars in the parkinglot, making room for recycling construction debris.Determining Load Carrying Capacity for Vegetated RoofPrior to designing the vegetated roof, the building had to beexamined to determine if it could support the roof’s weight.With none of the original construction drawings available,WTI had to conduct physical testing to determine loadcarrying capacity. “Structural members of the building wereexamined through walls to determine the size of supportinggirders and columns,” said Nelson. “These invasive tests werecompleted at night and on weekends so as not to disturbemployees. We found that the building could support over170,000 pounds of engineered soil, and the vegetated roofwas designed accordingly.”Capturing Water for Onsite UseWhen installing a rain water harvesting system that cancapture, filter and hold 15,000 gallons of water, the biggestquestion is where to put the enormous water capturereservoir. Tremco’s is buried beneath its parking lot, wherea pumping station ties in to the city’s main storm sewer.Captured water is used to irrigate the vegetated roof andgrounds around the headquarters building.Installing New Façade Over Existing SlateBecause removing the exterior slate façade of the existingbuilding was not possible while the building was occupied,a new exterior façade treatment was devised to be installedover the existing slate. Tremco’s Commercial Sealants &Waterproofing Division and Dryvit Systems collaborated withWTI to design the new façade, which serves as an air barriersystem where none had existed before. To ensure adhesionto the existing slate, testing was successfully conducted withDryvit’s Outsulation Plus MD System .Scheduling, Timing, BudgetingTiming was most certainly everything during the Tremcorenovation. Originally slated for two construction seasons,the construction schedule was compressed into five monthsby carefully coordinating the concurrent work of a multitudeof trades. Weekly scheduling, progress and costing meetingskept the project on schedule and on budget. Throughoutthe process, the WTI team maintained a full constructionschedule, just as everyone else involved in the project carriednormal workloads.5
Sealing theBuilding EnvelopeThe following measures were taken to effectively sealthe building envelope of Tremco’s headquarters building.AIR BARRIER An air barrier audit by Canam Building EnvelopeSpecialists identified numerous leaks throughout the buildingenvelope which were remedied by the new Dryvit façadeand high performance window system. Tremco CommercialSealants & Waterproofing’s ExoAir 110LT Self-Adhered Air& Vapor Barrier Membrane was installed around the roughwindow openings and their Proglaze ETA EngineeredTransition Assembly sealed with Spectrem 1 Silicone Sealantwas used to ensure a secure, durable, airtight seal betweenthe window system and the building façade. Benefits of thenew, functioning air barrier system include improved indoorair quality, temperature control, energy efficiency andextended building life cycle.FAÇADE Dryvit’s Outsulation Plus MD System was installeddirectly over the existing slate façade, eliminating the timeand expense of removing the slate and disposing of it in alandfill. (Slate from the mechanical room’s façade, however, wasremoved and recycled as a walkway on the vegetated roof.)Outsulation provides exterior continuous insulation, a highperformance moisture drainage system and a durable exteriorfinish. The finish texture chosen was Dryvit’s TerraNeo , whichgives the look of granite to the newly retrofitted structure.Employees who work in the building voted to select the color.6WINDOWS The high-performance window system wasconstructed on-site, incorporating numerous TremcoCommercial Sealants & Waterproofing products in the glazingsystem to ensure compatibility, long-term performance andairtight transitions. These included Spectrem 2 Silicone Sealantfor the metal-to-metal connections and structural tensile bead,spacer gaskets of SCR-900, and pressure bar gaskets of ourperoxide EPDM with the Proglaze ETA Engineered TransitionAssembly at the window-wall interface. The new windowsystem uses recycled aluminum and features double-panetinted windows that exceed minimum energy standards.MECHANICAL ROOM ROOF Tremco Roofing’s TPA whitethermoplastic single-ply roof system provides a highlyreflective white surface to help decrease surface temperatureand reduce energy costs. The roof system is approved byENERGY STAR , UL, FM Global, California’s Energy Standard Title24 and the Cool Roof Rating Council.PARAPET WALL The height of the parapet wall surroundingthe vegetated roof was increased to improve safety on theroof and to coincide with the higher vegetated roof level. Itsconcrete block was sealed and waterproofed with TremcoRoofing’s Wall-Tite, to provide a flexible “breathing” membrane.TremLock Series II “R” panels were installed to aid in acontinuous waterproofing seal in conjunction with the flashing.
WALKWAYS New concrete walkways were installed,including durable custom-designed decorative concreteby Increte Systems , a division of The Euclid ChemicalCompany.ENTRANCE CANOPIES The building’s east canopy roofwas replaced with Tremco Roofing’s unique Rock-It system, featuring a highly reflective white gravel surfaceembedded in white adhesive that helps lower energyusage and slow the roof aging process. The west canopyroof was made over as a beautiful and self-sustainingvegetated roof.ENTRANCES A new interior vestibule was constructed atthe employee entrance to keep unwanted outside air frominfiltrating. Power-assisted doors, an ADA upgrade, wereinstalled at the main entrance.THE INTEGRITY OF THE BUILDINGENVELOPE IS KEY TO A HIGHPERFORMANCE BUILDING BECAUSE ITVEGETATED ROOF The vegetated system is the crowningglory of the renovation. Recycled slate and raised walkwayscircumscribe the rooftop blooming with more than 16,000plants from 46 species. Four distinct horticultural areasare designed specifically for the local climate. The LEED friendly vegetated roof helps to reduce the demand onthe heating and cooling system, improve air quality andaesthetics and extend the roof‘s life cycle through superiorweathering protection.SOUTH BUILDING On the headquarters campus’“south building,” a new outside stairwell features a skylightto provide natural light, slip and corrosion-resistantFibergrate stairs, and a lightweight Dryvit façade thatmatches the building’s brick beautifully.DIRECTLY IMPACTS A BUILDING’S ENERGYUSE THROUGH HEAT GAIN AND LOSS.7
Interior ImprovementsLIGHTING SYSTEM RETROFIT The installation ofinfrared occupancy sensors meets mandatory controlrequirements and keeps lighting energy consumptionto a minimum.LOBBIES Stonhard installed a beautiful and durable newlobby floor. New wall and door finishes were achievedwith products from Carboline and Modern Masters.MECHANICAL ROOM Inside the penthouse mechanicalroom, Tremco sealants were used to seal off numerousair leaks. The return air system was modified with Tremcosealants to eliminate air loss. The floor was given afacelift with a durable Carboline Sanitile 555 floor.8Both energy efficiency and aesthetics wereconsidered in the numerous updates madeto the interior.The renovation of the mechanical room createdsignificant additional space that allowed a conferenceroom to be added adjacent to the vegetated roof.RESTROOMS REMODELED Mandatory water usereduction was achieved by installing water-conservingfixtures in all restrooms and the kitchen area. Upgradesalso made the first floor restrooms ADA compliant.ELEVATOR MODERNIZED The elevator’s operatingsystem was optimized; ADA upgrades included theinstallation of audible and visual signals, Braille andlower call buttons.
The building’s heating and cooling requirementschanged dramatically after the proper sealingof the building envelope. Old equipment wasreplaced with energy-efficient components suitedto the new demands of the renovated building.HVAC HEATING SYSTEM Two variable speedheating pumps were installed for more efficientoperation. The piping system of the existingboilers was modified to achieve variable hotwater flow. The entire perimeter radiationsystem was removed as a result of the increasedperformance of the building envelope.HVAC COOLING SYSTEM The cooling systemreceived an overhaul with the installation of anew, variable speed, dual cell cooling tower; twonew variable speed chillers; and new, variableflow pumping systems. This equipment allowsfor greater energy efficiency by modulating flowand capacity and is precisely matched to thebuilding’s new cooling requirements.HVAC AIR DISTRIBUTION Distributionsystem components were converted to variableflow for more efficient operation. An energyrecovery ventilator, communication network andoccupancy sensors were also installed to meetmandatory energy requirements and improveoperational efficiency.HVAC System UpgradesHVAC CONTROL SYSTEM A facility-wideBuilding Automation System that incorporates“open protocol” communications controls andmonitors all HVAC, lighting and renewableenergy systems was installed. “Revenue Grade”submetering is utilized to monitor the energycontributions of the renewable energy resources.9
Renewable Energy andSustainable SolutionsTo lessen the carbon footprint of the three-buildingTremco campus and generate “clean” energy, theretrofit included a number of innovative renewableenergy and sustainable solutions.PHOTOVOLTAIC Two solar arrays wereinstalled, one on the roof of the southbuilding and the other atop the newcarport, and are expected to generatea combined 100,000 kWh annually. Thecarport includes four solar-poweredelectric vehicle charging stations, withroom for additional stations, and funnelspower to the headquarters building whenthe charging stations are not in use.WIND TURBINE Up to 6,000 kWh peryear is expected from the wind turbineinstalled on the campus. The turbinehas an instantaneous power rating of1.8 kW at winds of 25 mph.VEGETATED ROOF The four uniqueenvironments planted on Tremco’svegetated roof help to cool air throughevapotranspiration, lessen the heatisland effect, and improve air quality bylowering greenhouse gases and airborneparticulates, all important environmentalconsiderations. Included in the plantingsare the award-winning BioTray VegetatedRoof Delivery System and herbs grownfor use in Tremco’s cafeteria. The roof alsoprovides a habitat for a wide range ofinsect and bird life.RecyclingIn a project of this magnitude, generatingmore than two million pounds of construction debris, it is amazing that every bit wasrecycled, reused or burned for energy. Thisincluded: slate, wood, asphalt, concrete,non-ferrous metal, glass and other windowmaterials, as well as built-up roofing systemcomponents such as insulation and gravel.Asphalt from the built-up roof was combined with asphalt from a road project andused for parking lot repairs. Sinks, blindsand other reusable items were donated toHabitat for Humanity.10RAIN WATER HARVESTING A 3,000gallon reservoir placed under the parkinglot is the collection point for Tremco’sonsite rain water harvesting system.Collected water is pumped to a two-partfiltration system and stored in one of sixstorage cisterns which collectively hold12,000 gallons of water. The water is usedto irrigate the building’s ground levellandscaping and, when necessary, thevegetated roof, eliminating the use ofcity water for irrigation and reducing thevolume of water flowing into the stormdrainage system.DAYLIGHTING The deep-well skylighton the south building’s new staircasediffuses natural light, reducingdependence on electric lights.
WTI General ContractingThe elaborate phasing plan for the approximately five month renovation project was orchestrated by WTI’s general contractingdivision. Employing its signature engineering, procurement and construction management method, WTI was responsible for allfacets of Tremco’s sustainable makeover. As experts in whole building retrofits, WTI was responsible for everything from schematicdesign and material selection to on-site project management to implementing innovative sustainable technologies andrenewable energy solutions. WTI specializes in integrated repair, restoration and retrofit services and is dedicated to improvingbuilding performance while reducing life-cycle costs. It offers turnkey financial analysis for program payback, specificationdevelopment, system installation and ongoing maintenance of green building retrofits.Retrofit Yields Savings & AccoladesIn the first full fiscal year after constructionwas complete*, we reduced gas use by67% and electricity by 33%. Supported byearlier plumbing changes, we used 32% lesspotable water (saving more than 250,000gallons).Renewable energy sources are playing a partas well; the solar arrays and wind turbinehelp power the headquarters building. Withthe building envelope sealed and the HVACsystem optimized, employees are enjoyingan increased level of comfort. In addition, thecompany expects the property value to riseupon reassessment. Ongoing commissioningwill ensure that the building will continue tofunction as designed, maintaining its highperformance.Businesses considering renovatingcommercial facilities for greater performanceshould first determine how much energythey use annually per square foot (calledAwardsthe Energy Utilization Index). Plans canthen be developed with a goal of saving20 to 25% annually in energy use andachieving an ENERGY STAR rating of at least75. Subsequent savings can be re-investedin further improvements or maintenance.Tax credits and low interest loans are oftenavailable to help fund the renovation.The business community has taken notice of theretrofit with the following awards:An important part of any high performanceproject is sanctioning by the U.S. GreenBuilding Council’s LEED (Leadership inEnergy and Environmental Design) program.In February 2012, the U.S. Green BuildingCouncil certified the Tremco building asLEED Gold, its 72 points far surpassing theminimum requirement for Gold status.The renovation was so extensive that thecertification is for new construction, makingthe building LEED-NC. BioTray was also deemed one of the 67best money saving products by BuildingsMagazine*Figures compare our fiscal year 2012 use with the averageannual use for fiscal years 2008-2010; fiscal year 2011 wasexcluded due to construction.
