4 ENERGENCE ULTRA-HIGH-EFFICIENCY AND HIGH-EFFICIENCY ROOFTOP UNITS At Lennox, we re committed to building innovative products that can help save energy costs and reduce operating expenses. Our family of Energence rooftop units delivers on both counts. It achieves efficiency ratings up to 23.5 SEER and 22.0 IEER the highest on the market today* to provide significant savings throughout the year. And it s engineered with intelligent features, like our Prodigy 2.0 Unit Controller, that make service and maintenance extremely cost effective and easy. 3

5 ENERGENCE FAMILY For spaces like classrooms, gymnasiums and auditoriums, the Energence family of rooftop units, featuring Energence Ultra-High-Efficiency and High-Efficiency models, can provide the energy savings and comfort control needed to efficiently maintain ideal environments for learning. The Energence family of rooftop units offers advanced technologies and the flexibility to choose the right tonnage and options for each unique application. Unique customization Each Energence unit is configured to order and customized for your specific light-commercial application: More than 3 million possible factory configurations Fully customized units, delivered in 4 to 6 weeks; standard-configured units in stock Over 100 field-installable options for added customization Quick installation and service All Energence units include features that help make installation and service quick and easy for technicians: Isolated compressors enable quick access and confirmation of refrigerant charge Slide-out indoor blower for ease of service and cleaning Accessible gas components are easily reached to confirm proper operation Hinged panels with handles allow quick access to all key components and eliminate the risk of losing panel screws during service *Efficiency based on AHRI directory, January 12,

6 ENERGENCE ULTRA-HIGH-EFFICIENCY Energence Ultra-High-Efficiency units can provide the energy savings and comfort control needed to maintain the ideal environments for learning. Ultra-high-efficiency The efficiency ratings achieved by Energence Ultra-High-Efficiency units exceed ASHRAE IEER minimum standards by as much as 96%. Ultra-lightweight design Energence Ultra-High-Efficiency units are packed with intelligent features, yet are up to 47% lighter* than many leading competitors units, reducing concerns and potential costs involving a building s structural integrity. Ultra-quiet performance The variable-speed compressor or Advanced Cooling System, DirectPlus blower system and ECM outdoor fans help reduce outdoor sound levels to the lowest in the industry as low as 73 dba making Energence Ultra-High-Efficiency units ideal for schools. Studies have shown that the performance of school children is impacted as much as 20% by the negative effects of a poor indoor environment. SOURCE: Wargocki, P., D.P.

7 ENERGENCE ULTRA-HIGH-EFFICIENCY Reduced temperature swings School buildings often need smaller tonnage units but this doesn t have to mean less comfort. Energence Ultra-High-Efficiency 3- to 6-ton units are engineered to deliver ultra-precise heating and cooling. The modulating, variable-speed compressor and indoor blower ramp up or down to closely match the load in the classroom. This can reduce or eliminate the temperature swings that can occur with single- or two-stage systems. It also helps keep humidity levels in balance. MAXIMUM MINIMUM SINGLE-STAGE MOTOR: Since it s either full speed or completely off, a single-stage motor creates continuous temperature cycling throughout the day. MAXIMUM MINIMUM TWO-STAGE MOTOR: With the ability to operate at two different speeds, a twostage motor creates temperatures that are more even and steady, with only mild temperature cycles throughout the day. MAXIMUM MINIMUM VARIABLE-SPEED TECHNOLOGY: Variable capacity and a variable-speed motor let the system maintain consistent temperatures without temperature cycling, preserving your perfect temperature and your perfect environment throughout the day. SPOTLIGHT: 3- TO 6-TON APPLICATIONS The most recent addition to the Energence Ultra-High-Efficiency lineup. The most efficient rooftop units in their class * Up to 23.5 SEER, 15.0 EER and 22.0 IEER the highest on the market today Exceeds ASHRAE by up to 96% Exceeds ASHRAE by up to 73% Greater humidity control Properly designed schools utilize more outside air, which can introduce additional humidity, causing discomfort in the classroom. The modulation of Energence Ultra-High-Efficiency units extends the time that the unit is running, and maintains comfort. In addition, these systems have an Increased Dehumidification Mode (IDM), which will modulate the compressor and reduce the speed of the indoor fan to remove additional moisture from the classroom. Enhanced heating comfort Energence Ultra-High-Efficiency 4- to 6-ton models have an optional 4 stages of gas heating, which adjust to match the classroom temperature requirements. As the weather outside fluctuates and more or less heat is needed, the system will adjust to provide the necessary warmth.

22 INDOOR AIR QUALITY CREATING A BETTER ENVIRONMENT THROUGH IAQ It s difficult to overestimate the impact of Indoor Air Quality (IAQ). According to the EPA, poor IAQ is among the top 5 environmental risks. Pollutants in a school s air can cause dizziness and headaches, as well as aggravate allergies and asthma. While cleaning and vacuuming can improve indoor air, cleaning alone will not solve IAQ problems. EFFECTS OF IMPROVED IAQ School Performance 10% Increases of 5 10% by doubling ventilation Absenteeism 35% Reduced by 35% by doubling ventilation Sick Building Syndrome 33% Decrease of 33% in symptom prevalence rates as ventilation rate increases from 17 to 50 cfm per person Source: 21

23 HOW IMPROVED IAQ CAN MAKE A DIFFERENCE Good IAQ carries numerous benefits. It can help improve the health and productivity of students, decrease absenteeism, and increase learning and student performance levels. LENNOX HVAC SOLUTIONS FOR IAQ Humidity Control Reduces humidity without overcooling rooms Helps prevent growth of mold and bacteria Controls spread of allergens Fresh Air Ventilation Products Help reduce concentrations of odors and VOCs Dilute indoor air pollutants Fresh air can be supplied indoors according to design or occupancy levels High-Efficiency Air Filters Reduce concentrations of dirt, pollen, dust mites, mold spores, fungi, odors and chemicals Enhance comfort Help protect furnishings Help prevent discoloration of walls and ceilings UVC Germicidal Lights Reduce concentrations of mold, bacteria and fungi on coils Minimize irritants and increase comfort Maintain system efficiency by keeping the coils clean According to the U.S. Environmental Protection Agency, the annual energy bill to run America s primary and secondary schools is a staggering $6 billion more than what is spent on textbooks and computers combined. Approximately 40-60% of that cost can be attributed to heating, cooling and ventilation. Source: Managing energy costs in schools, Xcel Energy lennoxcommercial.com 22
