Tremco Inc., a part of RPM International Inc.’s RPM Building Solutions Group, said a $5 million renovation program for its headquarters building in Beachwood, Ohio, will “transform the building into a showcase of sustainability.”
The company said it plans to seek LEED Gold certification for the building, which was originally built in 1970. LEED is the U.S. Green Building Council’s Leadership in Energy and Environmental Design green-building rating system.
Tremco said a number of sustainable-building systems for the “top-to-bottom” renovation program will be supplied by RPM Building Solutions Group companies, including:
• Canam Building Envelope Specialists (interior air sealing);
• Increte Systems, a division of Euclid Chemical Company (decorative concrete);
• Tremco Commercial Sealants & Waterproofing (sealants and gaskets); and
• Tremco Roofing and Building Maintenance (vegetated, cool and photovoltaic roofing systems).
Also incorporated into the project will be an Outsulation® insulated exterior wall cladding system from RPM sister company Dryvit® Systems Inc.
Tremco Inc. subsidiary WTI will act as general contractor for the project, which includes the management and training of all subcontractors.
“This renovation gives us an exceptional opportunity to show our commitment to sustainability to our customers, staff, suppliers and others,” said RPM Building Solutions Group President Randy Korach. “We intend to create a truly high-performance, sustainable facility that integrates our rich array of corporate solutions and highlights the use of construction best practices.”
Korach said the company’s objectives are to improve energy efficiency and conserve water; reduce operational costs; provide a safer, healthier facility for employees; and protect the natural environment by reducing carbon output, lowering the local heat-island effect, and recycling and reusing materials.
Tremco Inc. said the renovation program’s most noteworthy sustainable features include the following:
• A vegetated roof featuring local plants; low-impact lighting and a water-capture system integrated with the roof; and a pathway of recycled materials. Signs will describe the roof’s features and provide information about the plant palette.
The roofing systems also will include the ENERGY STAR® qualified Rock-It™ roof-surfacing system, composed of white gravel set in white adhesive, and a white, reflective, single-ply system installed beneath a rooftop photovoltaic (PV) system. A thin-film rooftop PV system will be used to generate electricity for the building.
• A Dryvit Outsulation Plus® MD exterior wall system featuring Dryvit’s TerraNeo™ finish. The system provides an energy-efficient, insulated façade and can be applied directly to the existing slate, eliminating the time and potential waste of removing the façade.
• High-performance, double-pane, tinted windows that exceed minimum energy standards. Tremco sealants and gaskets will be used, as will Tremco’s Proglaze® ETA (Engineered Transition Assembly) to ensure an airtight transition from window to wall.
• New sidewalks, with decorative concrete from Increte Systems, that will be supported by gravel from one of the building’s existing roofs.
• A 1.8-kilowatt-rated wind turbine installed on the property to help generate electricity.
• Numerous interior upgrades such as ADA-compliant restrooms, interior-window treatments, and elevator modernizations with eco-friendly technology and ADA compliance.
• Mechanical/engineering/plumbing upgrades such as a new control system that ensures an accurate operating schedule of HVAC and lighting as well as improved zone control; modifications to the central air handling system to enable variable flow, resulting in significant energy savings; and replacing the cooling tower with a variable-speed model that also eliminates the need for water treatment.
Construction best practices that WTI and its subcontractors will follow to increase the project’s sustainability include:
• Onsite sorting of materials;
• Recycling of all non-hazardous material;
• Chain-of-custody documentation for all off-site recycling;
• Reusing materials as applicable; and
• Verifying that materials are certified for LEED credit
The company said that to support the effort to attain LEED Gold certification, an independent commissioning agent will verify the impact of the various solutions on building performance.
