GOLD: SunSourceÂ® Commercial Energy SystemThe Lennox Industries SunSource® Commercial Energy System is a commercial HVAC system that incorporates the premium Energence® rooftop unit (RTU) line with an easy-to-install solar energy system. The system can be installed on rooftops of virtually any shape or size for any building where a 3- to 6-ton Energence rooftop unit will be used. The SunSource system is available only for use with Energence units, which is an RTU rated up to 17 SEER. Installation of the SunSource modules can be completed in a single day, due to a plug-and-play modular design. Instead of tying all solar panels in a series to a single string inverter, the SunSource system uses microinverter technology so it continues to operate even if a panel fails. Energence rooftop units used with the SunSource system include all the features of the original RTUs, including the color-coded SmartWire® system for faster, easier installation and the Prodigy® control system for operation verification to reduce start-up issues. The SunSource modules arrive as a package to the job-site with up to 21 modular panels and hardware included; the panels are easily mounted and activated by the contractor.

SILVER: MaverickThe Maverick MPS 15-50F by McQuay International is a packaged rooftop unit from 15-50 tons with MicroTech III DDC integrated control, BACnet or Lon Talk communications, up to five stages of capacity control, modulating furnace for up to 100°F temperature rise, optional modulating hot gas reheat, airfoil plenum fan, and optional energy recovery wheel. Features that make installers and servicers work faster and simpler include a hinged access door on both sides of every section, a factory run test of the entire unit and controls, a double wall air-handler cabinet that is more robust and easier to clean, and the MERV 6 construction filters, which are factory-installed. Also, the factory-installed VFDs for supply and exhaust fans are complete with static pressure control for both; the microchannel condensers are more robust, easier to clean, and requires less refrigerant charge, says the company.
BRONZE: Daikin AC Round-Flow CassetteThe Daikin AC Round-Flow Cassette FXFQ_PVJU features a built-in condensate pump, eliminating the need to purchase one locally at the time of installation. Outside air integration is possible. The unit measures just 11 (length) by 33 (width) by 33 (height) inches, and installation is easier due to a reduction in weight and a lightweight fan that also improves efficiency, said the manufacturer. The design of the Round Flow ceiling cassette features a new drain pan structure and discharge grille style, resulting in effective and uniformed 360-degree air distribution into the space. The unit features a hollow, serrated design turbo fan combined with a new high-efficiency fan motor. Installation and service benefits include built-in self diagnostics, and it comes standard with a washable filter.
