GOLD: CREST Condensing BoilerThe CREST® Condensing Boiler offers innovative fire-tube technology integrated with the exclusive Smart Touch™ operating control, offering engineers, mechanical contractors and building owners greater design flexibility and distinctive performance characteristics to meet today’s building standards for new construction and energy retrofit applications. Available in five models that range from 1.5 to 3.5 million Btu/hr, with thermal efficiencies as high as 99 percent, CREST brings Lochinvar’s leading-edge technology and exceptional energy-efficiency to the largest commercial applications.
SILVER: Climate WizardClimate Wizard is an indirect evaporative air conditioner that uses a unique counterflow heat exchanger to deliver air that approaches the ambient dew point temperature, but adds no moisture as it cools. The product has been independently tested by the University of South Australia, showing that it achieves a coefficient of performance of more than 13 and itt can reduce energy use by up to 80 percent, depending on the application and conditions. One of Australia’s award-winning architects, John Maitland from Energy Architecture, said that he first questioned the name Climate Wizard. But, now that he’s specified the product in several projects, including his own home, he’s a strong advocate of the product and the technology. Interest in the product has been reinforced by several awards, including the GAIA Gold Award at the 2010 Big 5 Show in Dubai and the HVAC Product Excellence Award at the 2010 ARBS Expo in Australia, as well as the 2009 Green Plumbers Energy Efficient Product of the Year.
BRONZE: McQuay Delivered VAV SystemThe McQuay Delivered variable air volume (VAV) system combines web-based touch-screen system controller with VAV terminal boxes and air handling equipment such as rooftop air conditioners. This system is a cost-effective, easy to install way to get the benefits of variable air. volume efficiency and comfort for small to medium-sized buildings. Ancillary devices as a boiler or exhaust fans can be interlocked to the system schedules in the field. Up to 100 total devices can be connected in a system. With the McQuay Delivered VAV System, field start-up of an entire building* can be typically be completed in hours compared to days. [*building VAV system consisting of two 50-ton rooftops and 20 to 40 VAV boxes.] After the system is installed the Delivered VAV system components automatically communicate with each other thanks to the data preloaded at the factory. The commissioning process is automated as a result of the start-up wizard and easy-to-use touch screen controller.
