The beginning of the school year is also a good time to optimize HVAC scheduling. Before the first bell rings, ensure that any building automation systems are set to match occupancy schedules accurately. Turning down HVAC systems or setting them to unoccupied temperature setbacks during evenings, weekends, and holidays can lead to significant energy savings without compromising comfort during school hours.
Step Up to More Comprehensive Strategies:
The back-to-school season also presents an opportunity to consider more comprehensive strategies that offer long-term benefits. Retro-commissioning existing HVAC systems every 5-10 years is a highly effective "tune-up" that optimizes performance, reduces energy consumption, and improves IAQ. This process identifies inefficiencies and makes adjustments to ensure systems are operating as intended, leading to better ventilation and substantial energy cost reductions.
This might also be the year to consider HVAC equipment retrofits. HVAC retrofits range from small retrofits to complete equipment replacement. To get the most return on your investment, consider retrofits that will increase ventilation capabilities, improve air distribution and filtration, and add control/monitoring capabilities. Federal tax credits are also still available for non-taxpaying entities like school districts to purchase efficient geothermal heat pumps.
Finally, explore opportunities to combine IAQ improvements with energy efficiency upgrades during broader planned renovation projects. For instance, coupling HVAC system upgrades with improved insulation and air sealing can dramatically reduce energy consumption while enhancing comfort and air quality.
By prioritizing these strategies, from simple adjustments to investing in larger capital improvements, school business officials can help ensure school environments are not only cost-effective to operate but also healthy, comfortable, and conducive to learning and well-being for everyone.
