Healthy & Successful Students

Multiple studies have measured student benefits of views, daylight and thermal comfort:

• Daylight - Students in classrooms with the most daylight showed a 21% improvement in learning rates1,2

• Views - Researchers found an association between academic achievement and classroom views to the outdoors1

• Glare - Direct sun penetration into classrooms, especially through unshaded east or south facing windows, is associated with negative student performance, likely causing both glare and thermal discomfort1

• Thermal Comfort – Reducing air temp by 1.8 F improved student performance in terms of speed from 2 – 4% in all tasks3

Healthy & Successful Staff & Faculty

Multiple studies have measured human benefits of views and natural light:

• Workers with views were 6 – 15% more productive than workers with no views1,2,4

• 10 - 15% of absenteeism can be attributed to working spaces with no connection nature2,3

• Access to views and daylight is shown to improve occupant overall wellness5,6

CPTED and Natural Surveillance

#1 Recommendation - Natural surveillance increases the threat of apprehension by taking steps to increase the perception that people can be seen. Natural surveillance occurs by designing the placement of physical features, activities and people in such a way as to maximize visibility and foster positive social interaction among legitimate users of private and public space. Potential offenders feel increased scrutiny and limitations on their escape routes.
