As educational institutions strive to create healthier, more energy-efficient and student-centered learning environments, natural daylighting has emerged as a key design strategy that supports sustainable and inclusive learning design. A well-planned daylighting strategy offers numerous sustainability benefits and can enhance key design principles that are shaping the future of educational spaces

The Benefits of Sustainable School Design

1. Healthier Indoor Environments

Sustainable school design creates healthier learning environments by improving indoor air quality, natural ventilation and daylighting. High-efficiency ventilation systems filter out airborne pollutants, while sustainable materials and finishes reduce exposure to harmful chemicals.

Natural daylight, a critical element of healthy indoor spaces, offers a dynamic lighting alternative to static electric lighting solutions, which can adversely affect the building occupants’ mood, sleep patterns and overall well-being. The daily progression from darkness to physiologically meaningful dynamic daylight and back supports the body’s time-dependent production of serotonin and melatonin, enhancing mood regulation, attention span and overall student engagement.

Recent discoveries about have further underscored the importance of daylight as a source for interior space illumination. These cells play a vital role in regulating circadian rhythms, paving the way for evidence-based daylighting design strategies. By integrating these insights with modern architectural and engineering principles, sustainable schools are better equipped to optimize learning environments.

2. Higher Attendance and Teacher-Retention Rates

Sustainable school design not only creates healthier learning environments—it also boosts attendance and teacher retention. A survey of 665 industry executives revealed that more than 70% of respondents saw reduced absenteeism and improved performance in green schools. Complementing this, a nationwide survey found that nearly all teachers (97%) consider effective learning environment design essential for student success, with 80% linking it to effective teaching and 68% factoring it into job decisions.

Key features—such as improved indoor air quality, reduced chemical emissions, abundant natural daylight and better humidity control—yield environmental, fiscal and health benefits. These advantages lead to lower absenteeism, reduced turnover and enhanced performance, with a 2011 study showing up to 7.5% improvement in attendance and an 8% to 19% boost in student performance when compared to conventional schools.

3. Improved Student Performance and Test Scores

The relationship between sustainable school design and academic performance is also well documented. from the Lighting Research Center (LRC) and other academic institutions shows that exposure to natural daylight in classrooms enhances cognitive function, improves memory retention and reduces stress and fatigue. In fact, a by the Heschong Mahone Group revealed that students in naturally daylit classrooms advanced 20% faster in math and 26% faster in reading compared to those in environments with limited daylight. Additional studies indicate that classrooms with optimized natural daylighting contribute to increased productivity, better concentration and higher overall academic achievement.

4. Reduced Environmental Impact

K-12 schools spend roughly $8 billion annually on energy and emit approximately 72 million metric tons of CO₂—equivalent to 18 coal-fired power plants per year—according to the U.S. Department of Energy. By adopting sustainable design strategies, especially natural daylighting, schools can lower energy consumption, reduce emissions and create healthier learning environments.

A well-designed daylighting system reduces reliance on electric lighting, which can account for 35% to 50% of a school’s annual energy use. Daylight has a higher efficacy factor compared to electric lighting, providing more light with less heat. As a result, maximizing daylight can lower cooling demands by up to , easing the load on HVAC systems, and can reduce electric lighting consumption by up to . These energy efficiencies translate into significant cost savings and a reduced environmental footprint.

5. Lower Operating Costs

Lastly, schools designed with sustainability in mind benefit from significantly lower long-term operational costs. High-performance buildings utilize strategies such as natural ventilation, enhanced insulation and geothermal heating to reduce energy consumption and improve efficiency. According to the , green schools, on average, use 33% less energy and 32% less water than their conventional counterparts, saving roughly $100,000 per year in direct operating costs.

MIDVALE, Utah — Anyone who has ever muddled with programming will know the turn of phrase “feature or bug?” It’s the industry’s glib way of spinning what might be an interesting deviation in the code. The same applies to interior design when it comes to schools — at least according to a recent newscast on New4Utah regarding a pending $100 million retrofit to Hillcrest High School (HHS) in Midvale, Utah, which is still in the design phase. The question at hand is “Are large windows a design feature or potentially fatal flaw?”

Included in the proposed design is plenty of “” in the form of large windows, which the area’s Canyon School District has been employing throughout its schools. The premise holds that natural light is not only good for defraying electricity and infrastructure costs but it’s also healthier for students and promotes a positive learning environment. At least one teacher, however, believes the new window design makes students and faculty vulnerable to school shooting incidents, according to the report.

Katie Bullock, a language arts teacher at the high school, candidly told the TV station, that she believes greater visibility of students essentially makes them easier to target and that the design represents “negligence” on the part of the district. Jeff Haney, a Canyons School District spokesperson disagreed with the observation, countering that “These are schools, not prisons.” Though there were discussions of reducing the size of the window to 10 by 6 feet, Bullock pointed out that they will not be made of bullet-proof glass, which moots the point of shrinking the windows in the first place.

HHS principal Gregory Leavitt posted a message on the school’s following a recent parent and student public forum. “We had over 250 students share their thoughts and opinions about HHS. Our parent meeting had 25 participants, and we are hoping for more next time. We have published a summary of our student and patron comments and the HHS response for your review on our web page. We hope you take the time to look them over and join us in our next public forum,” wrote Leavitt.

To that end, the district and  Architects, a Salt Lake City-based firm that designed the proposed upgrades, will share renderings of the new HHS on April 18. The public is invited to come look over the architectural drawings and speak with school officials and architects. Construction of the new school is slated to begin this Spring and could take up to three years to complete.

HHS has a total enrollment of about 2,250 students and is ranked No. 7 in the state of Utah. Students from HHS participated in a walkout one week after 17 people were killed in the Marjory Stoneman Douglas High School shootings in Parkland, Fla., in February. In February of the previous year, the school went on lockdown when an anonymous caller phoned the police to say that a gunman was barricaded inside the school and firing shots. The incident turned out to be a hoax.
