Indirect Evaporative Cooling for Schools & Classrooms
Schools face a dual challenge: keeping students comfortable while managing tight budgets. Educational institutions are urgently looking for smarter, cost-effective cooling systems for educational institutions to maintain healthy indoor air quality and temperature. Indirect evaporative cooling (IEC) is fast becoming a compelling alternative to traditional HVAC systems, especially for schools prioritizing energy efficiency, student performance, and environmental responsibility.
What Is Indirect Evaporative Cooling (IEC)?
IDEC is a cooling method that reduces air temperature without adding humidity—a critical advantage in classroom environments where humidity can affect comfort and indoor air quality. Unlike direct evaporative coolers, IEC systems use a heat exchanger to cool fresh incoming air via a secondary airstream that is moistened and cooled.
This separation of air streams makes IEC ideal for schools in humid or mixed climates, or spaces that require controlled ventilation like libraries, staff rooms, or computer labs.
Why Cooling technology for educational buildings is necessary?
Energy Efficiency That Cuts Costs
- IEC technology helps schools achieve energy-efficient school cooling by using up to 80% less energy than traditional air conditioning systems.
- Many institutions report 30–50% savings on cooling costs after adopting sustainable classroom cooling solutions like IEC.
Improved Indoor Air Quality
- IEC systems continuously draw in fresh outdoor air, effectively improving classroom air quality with evaporative cooling.
- Lower CO₂ levels help students stay alert, comfortable, and focused.
Sustainability and Green Certification
- IEC systems support green initiatives, including LEED and WELL certifications, by reducing carbon emissions and energy consumption—ideal for schools promoting sustainable classroom cooling.
Quiet, Distraction-Free Learning
- IEC units operate with minimal noise, creating a quiet, distraction-free learning environment.
- Compared to traditional HVAC systems, this cooling technology for classrooms ensures that students and teachers can concentrate without disruption.
Low Maintenance, Long Lifespan
- Because IEC systems for schools have fewer moving parts and avoid chemical refrigerants, they require less frequent maintenance and offer a longer operational life.

When comparing indirect evaporative cooling(IEC) vs traditional air conditioning in schools, IEC clearly offers better energy savings, lower maintenance, and improved indoor air quality, all while supporting sustainability goals.
Real-World Results from Schools
A district in California reported 47% lower HVAC costs within the first year of installing IEC across 10 classrooms. Teachers noted fewer student complaints about discomfort, and CO₂ monitoring showed a noticeable improvement in air quality, especially during high-occupancy hours.
“After switching to IEC, our classrooms stay cooler, and the energy savings are substantial—we now reinvest that into other student programs.”
