1 At 55% airflow when compared to full load.2 At 67% airflow when compared to full load.3 Select units will also require the equipment interface module.4 When considering all 2" filters with MERV 15 ratings at 492 fpm. Claim pertains to Lennox MERV 15 24"x24"x2" filter, which has the lowest pressure at 492 fpm among 2" MERV 15 filters. Claim references the reduced energy expense of running a lower pressure-drop media compared to a filter with a higher pressure drop, while maintaining high particle capture without increasing energy costs associated with fan energy consumption. Established through internal review of comparative literature available to the general public in June 2007.

5 As compared to uncalibrated parallel-blade-design dampers without the SmartAirflow System on a traditional 4-ton unit delivering 1,600 CFM (cubic feet per minute) of supply airflow with 15% outside air requirements where economizer minimum position is set at 15% damper position. Average of cities in ASHRAE climate zones 1-6. Savings will vary with each zone.

6 34 SEER, 43 IEER and beyond. Effective SEER and IEER estimates for the SunSource air conditioning system are based on the U.S. Department of Energy (DOE) annual performance factor (APF) method for heat pumps and air conditioners (10CFR part 430). Estimates of annual solar energy production are calculated using National Renewable Energy Laboratory’s (NREL) PVWatts, calculated at tilt angle 10 degrees with an 180 degree azimuth. Estimates of annual cooling operating cost savings for the rooftop units are calculated using Lennox’ Total Cost of Ownership Calculator, with operating hours from 10 am to 10 pm in a small retail environment in the Omaha region. Estimated SEER energy calculations were made using Energence LGH060H4E (5 ton/17 SEER 3-phase – 460V) and six 275DC W solar modules. IEER effective efficiency calculations were made using Energence LGH094U4E (7.5 ton/21.5 IEER 3-phase) and seven 275DC W solar modules. Note that SEER and IEER equivalents may vary by location.

* Claim pertains to 7.5- to 12.5-ton units listed in the AHRI ratings directory and available manufacturer data as of May 2014.
