Medical Research Facility Showcases Eco-Social Construction

Kemper System Belfer Medical Research Building

The rooftop on the Belfer Medical Research Building not only houses HVAC equipment but serves as a rainwater detention system. The reinforced membrane waterproofing system by Kemper System was applied to the roof deck before the pavers were put in place on a pedestal system.

The Belfer Medical Research Building on the campus of New York’s Weill Cornell Medical College was designed to be a 19-story model of eco-social construction. Designed by Todd Schliemann of Ennead Architects, the building showcases a number of sustainability features, including a storm water detention system on the roof.

Built for a cost of more than $630 million, the tower includes 13 stories of research laboratories. The tower has three roof levels at the 17th, 18th and 19th floors. The rainwater detention system, known as a “blue roof,” not only helps regulate storm water discharge, but it feeds a water fountain and irrigates planters on the second-floor terrace.

In general, rainwater detention systems can either collect water in holding tanks and then meter it to the public sewer system, or retain it on a waterproofed roof expanse. The blue roof on the Belfer Research Building uses the latter strategy. It complies with New York City requirements and can hold up to 3 inches of water.

Roof Materials

Proper waterproofing on the project is essential. The solvent-free and odor-free KEMPEROL 2K-PUR cold, liquid-applied membrane system was used for waterproofing the blue roof. It was also used on the terrace and fountains on the lower level. The reinforced membrane system is designed for long service life and backed by an extended-wear warranty.

Eagle One Roofing Contractors Inc. of Astoria, N.Y., a certified applicator of the Kemper System, applied the waterproofing system. The two-part resin system is designed to fully adhere to the substrate, and is fully reinforced with fleece. The resulting membrane is completely seamless and unaffected by ponding water and ice. According to the manufacturer, it resists exposure to UV light, chemicals, oils and solvents. It is impervious to bio-deterioration and is both root- and rot-resistant, so it is also ideal for green roofs and landscaped areas.

Roof Report

The supporting structure below the roof was designed to carry the water load, with an allowance for heavy snow or ice buildup. The roof deck is concrete slab and includes a layer of rigid insulation below the waterproofing membrane for added energy efficiency. The gravity-fed drainage system was carefully sized to control the speed of drainage without the use of pumps, sometimes required for rainwater detention systems that use holding tanks. On the roof sections, the waterproofing sections were topped with concrete pavers on a pedestal system.

Construction at the Weill Cornell Medical College, both interior renovations and new construction, is designed to meet a minimum LEED Silver status. This project was designed to achieve Gold certification, the nationally accepted benchmark for the design, construction and operation of high-performance green buildings.

On the south side of the building, Ennead created a double-skinned, fritted glass curtain wall with openings and sun-shading devices that absorb the sun’s heat before it gets trapped inside, which would require the HVAC system to pump out more cold air. Continuous ribbon windows flood the building with natural light, and energy-efficient HVAC, lighting controls and water-conservation systems save on power and resources. The building’s green infrastructure is expected to shrink Weill Cornell’s energy bill for it by about 30 percent and reduce carbon dioxide emissions by about 26 percent compared to a building complying with the minimum requirements set by typical industry guidelines and standards.

The building includes a high-tech, multi-zoned HVAC control system to manage the indoor environment within different spaces. Biomedical laboratories, for example, generally require special air filtration systems supported by high-volume air circulation. Each of the laboratory levels includes four fume vents to the outside, except for the chemistry laboratory on the top floor, which uses 40 vents. In addition to thermostats and humidity sensors, indoor spaces utilize occupancy sensors to assist in regulating the ambient indoor environment and lighting to improve energy efficiency.

Kemper System America Moves Office to the Top Floor of Heights Plaza in New Jersey

Kemper System America Inc. moved its New York metro sales office from Closter, N.J. to the top floor of Heights Plaza at 777 Terrace Ave., Hasbrouck Heights, N.J. 07604. The 200,000-square-foot office building gives ready access to major highways and transportation hubs and offers views of the Manhattan skyline.

“This is an ideal location for us to support our customers across the New York metropolitan region who include commercial architects, building owners and real estate management companies,” says Richard Doornink, president and managing director of Kemper System America, based in West Seneca, N.Y.

The company’s liquid-membrane waterproofing systems protect many iconic structures in the region, including the Empire State Building and the World Trade Center. Newer products span highly reflective ‘Cool Roof’ systems that help manage building energy from the top, and reinforced systems that add another layer of protection for indoor tiled areas.

ROOF MATERIALS

The Kempertec EP-Primer was used to prepare the substrate surfaces for membrane installation and served as a temporary waterproofing system, allowing the project to be exposed to the harsh New England winter while it was completed in phased stages.

The owners chose the Kemperol waterproofing and roofing membrane, a two-component with catalyst, high-performance, seamless and self-terminating cold-fluid-applied reinforced unsaturated polyester system. The monolithic edge-to-edge rot- and root-resistant Kemper membrane is engineered to resist degradation from UV exposure and heat intensity and is resistant to most common chemicals.

ROOF REPORT

Founded in 1811, Massachusetts General Hospital is the third oldest general hospital in the U.S. and the oldest and largest in New England. The 900-bed medical center offers sophisticated diagnostic and therapeutic care in virtually every specialty and subspecialty of medicine and surgery. When MGH’s owners envisioned constructing a new 9,000-square-foot green roof above the MGH cancer wing, they had two chief concerns: safety and long-term durability.

The landscaped roof design includes four different gardens with extensive shrubbery, trees and grass designed to provide cancer patients with a haven for relaxation and meditation to aid in the healing process.

A key challenge concerning the hospital’s green roof was its hundreds of penetrations, spaced inches apart, for a sprinkler system to irrigate the landscaped roof. A leak-detection system was installed across the entire square footage of the project to detect water before it seeps into the interior of the building. The leak-detection system confirms the project’s seal-tight success. Upon completion, Kemper System provided a 20-year, no-dollar-limit warranty.

The KEMPEROL Roofpatch Provides 50 Years of Waterproofing Technology in a Quick Kit

KEMPEROL Roofpatch is a ready-to-use patch kit from Kemper System America Inc., West Seneca, N.Y.

KEMPEROL Roofpatch is a ready-to-use patch kit from Kemper System America Inc., West Seneca, N.Y. Kemper System invented cold, liquid-applied, reinforced waterproofing technology more than 50 years ago, and the Roofpatch kit offers the company’s technology as a quick solution to reliably stop leaks and cover cracks and damaged areas.

“The product itself is a cold, liquid-applied membrane system,” says Gino Soroker, brand and business development manager for Kemper System America. “Typically our product comes as a container of liquid and a roll of fleece, and you need a contractor to put the two together. Here you get the two already married.”

The kit’s flat aluminum packaging includes rubber gloves and a reinforcement fleece pre-saturated in a single-component, solvent-free and odor-free KEMPEROL 1K-SF waterproofing resin. The reinforced membrane is pre-cut to approximately 10 by 18 inches; a single patch can handle most repairs. Patches also can be overlapped to cover larger areas.

The multipurpose patch adheres tightly without a primer to bitumen sheets, PVC roofing, concrete, wood and metal. The resin is rainproof in 60 minutes and can be walked on after 12 hours.

Soroker says the kit is ideal for roof consultants and roofing contractors, as well as building owners and property managers, seeking an immediate repair on a roof. “If a building superintendent or roofing contractor gets called up on the roof because a tenant reports a leak and he sees an overlap or a crack, he can rip open this aluminum pouch and slap on the roof patch right there and then,” he says. “If a specifier or consultant needs to cut open the roof to find out what’s happening beneath it,
he can put the piece he cut out back in, place this patch right over it and seal up the hole he just opened.”
