These products will keep your next project from being an energy guzzler. Eddy Urban Green Energy At just six feet in height, the Eddy wind turbine features a dual axis design that evenly distributes horizontal and vertical forces along the length of the axis for durability. In moderate wind speeds, it produces approximately 750 kWh of solar-ready power. In addition to IEC-certification for Wind Turbine Safety, Noise Levels, and Power Performance, Eddy is also ISO and UL certified. RecoupAerator 2000DX UltimateAir This commercial-grade energy recovery ventilator (above) features a proprietary wheel design made up of hydroscopic and non-hydroscopic materials in a random fiber matrix media for increased surface area, resulting in finer filtration. With an airflow capacity of up to 2,000 CFM, its comparison between two air stream temperatures (apparent sensible effectiveness) has been rated at 96 percent. It is also MERV 12 compliant. WebCTRL Automated Logic This web-based building automation system integrates major electrical systems, mechanicals, backup generators, fire systems, and building elevators. The program can also generate work orders for building system maintenance, bills for tenant’s off-hours use, and real-time pricing structures. Energy use trend reports and thermographic floor plans also tie into effective conservation features, such as setpoint optimization, optimum start times, and short-term demand reduction. Parans Solar Lighting Wasco For interior spaces without access to natural light, there is the Parans Solar Lighting system. Solar receivers mounted on the exterior of a structure channel solar energy along thin, flexible fiber optic cables that can be wound through a building’s infrastructure. The light is expelled through specially designed luminaires that deliver all the illumination benefits of natural sunlight, without electricity. Quantum Total Light Management Lutron A single system and software umbrella regulates lighting controls, motorized window shades, digital ballasts, LED drivers, and sensors. An enhancement for solar adaptation—for abundant sunshine, cloudy weather, or shadowed windows—automatically adjusts shades to meet prevailing conditions. A monitoring system also sends email alerts in the instance of alarming events or triggers that can be addressed with an iPad application, available for download at the App Store. Solar PV Canopy System Duo-Gard A turn-key approach to photo-voltaic architectural canopies: Solar energy is harvested for charging and lighting energy, or configured for energy credits. A steel frame, fabricated in-house, features a three-coat polyurethane epoxy finish for durability. The continuous canopy can be specified in Charcoal Gray or Blue, and in a sloped or ridged style.

Custom canopy scores big at Kansas City’s new soccer stadium.Kansas City’s Livestrong Sporting Park opened in June as the city’s first soccer-centric stadium and the new home of the Sporting Kansas City, the soccer team formerly known as the Kansas City Wizards. To make the arena both athlete- and fan-friendly, architect Populous envisioned a soaring roof canopy designed to evoke the arc of a soccer ball flying across the field. The team considered building the canopy with ETFE (ethylene tetrafluoroethylene) pillows, but desired a look more in line with glass panels. The weight of glass would have significantly increased the amount of steel substructure, in turn raising the canopy’s price. Working with Michigan-based architectural canopy design, engineering, and fabrication company Duo-Gard, the team began instead to develop a high-performance polycarbonate glazing system that minimized weight and maximized light transmission onto the field. In addition to its impact-resistance and long-span structural requirements, the canopy had to meet several programmatic demands. The architects wanted to create an intimate environment that would amplify the crowd’s noise, so the canopy had to cover every seat. While it would provide some shade for the audience, the structure also had to have enough light transmittance to maintain the natural grass preferred by Major League Soccer. The polycarbonate canopy would curve around the more than 1,800-foot stadium circumference, ranging from 25 to 70 feet in depth with a 1/12 pitch and 12-foot spans between structural members. “This kind of span hadn’t been done before by anyone with polycarbonate at a slight slope,” said Duo-Gard president David Miller. “Our engineers broke ground with this.” More than 100 feet above the ground, the stadium’s steel structure cantilevers 95 feet and supports a metal deck that transitions to the two-tiered clear polycarbonate deck, which is built with a 36-inch step-down to form a cavity for lighting and sound equipment. The 25mm triple-wall polycarbonate glazing allows 80 percent light transmission and integrates Duo-Gard’s 3 ½-inch aluminum profile at 32 inches on center to minimize shading. The framing system incorporates a custom engineered base plate, pressure plate, and curved cap that conceals canopy fasteners. According to Frank Kosciolek, Duo-Gard’s engineering manager, typical canopy systems have a 7-inch profile at 24 inches on center, creating more shadows and requiring an additional steel purlin. The team estimated that elimination of the extra purlin resulted in a 35 percent reduction in the amount of metal used. The system also met one and a half times of its structural loading requirements during testing. As home to the largest polycarbonate stadium canopy in North America, Kansas City’s sports scene is enjoying its moment in the sun.
