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 90.1 2010 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. Wyon 2006.

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 90.1 2010 by up to 96% Exceeds ASHRAE 90.1 2013 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.

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: www.iaqscience.lbl.gov 21

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
