Lennox International: Energence Ultra Rooftop Units | Lennox International

“Lennox International has set a new standard for commercial HVAC. Their Energence units not only have some of the highest SEER ratings in the market, but they have raised the bar by offering substantial control intelligence and direct integration with solar. By being the only manufacturer to integrate with solar, they are able to provide a real impact to a firm’s overall energy management initiative.”

Lennox’s ultra-high-efficiency Energence units feature industry leading efficiencies of up to 21.5 IEER and 13.9EER resulting in overall lower operating costs and service which contributes to the lowest total cost of ownership. Energence ultra-high-efficiency units are designed to offer customers ultimate energy savings with features such as the Advanced Cooling System and the DirectPlus blower system. In addition to sustained savings, the Energence ultra-high-efficiency lineup exceeds ASHRAE 90.1 minimum standards by 92 percent, exceeds CEE Tier 1 and 2 efficiency minimum requirements, and qualifies for many potential utility rebates and incentives, while also providing additional options to meet California Energy Code Title 24.

Energence ultra-high-efficiency models come standard with MSAV (multi-stage air volume) supply fan technology with the option of either the belt-less DirectPlus blower system or the belt-drive blower system. The DirectPlus blower system is a patent-pending design that combines the motor and electronics into one unit which uses fewer components and features slide-out access to help reduce maintenance time and costs.

Compared to standard-efficiency equipment, an Energence® ultra-high-efficiency unit can deliver significant energy savings over the life of the system. Energence® also provides near-endless opportunities for customization with every rooftop unit to help customers reduce their carbon footprint and qualify for many state and local utility incentives.

Built to suit a variety of applications, Energence ultra-high-efficiency units are backwards compatible with many existing Lennox rooftops, offering a simple solution for replacement applications. Up to 42% lighter than the competition, these units make it the perfect choice where rooftop structural integrity may be a concern, according to the company.

One judge called Energence ultra-high-efficiency units an “excellent product, producing real-time savings to the customer.”
