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
21%increase in student

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.
Top Strategy - Leave Blinds Open – No blinds with View!

2013 Title 24 Building
Envelope/Fenestration Requirements For
Non-Residential Buildings
All new building projects, other than acute care facilities, shall be designed, constructed, and commissioned to outperform the CBC energy-efficiency standards by at least 20%. The University will strive to design, construct, and commission buildings that outperform CBC energy efficiency standards by 30% or more, whenever possible within the constraints of program needs and standard budget parameters.

2013 Title 24: Challenges
• Meeting prescriptive envelope criteria with the 2013 Title 24 requirements is
more difficult compared to 2008
• Very few “clear low-e” glazing options currently available in the market meets the prescriptive requirements
• Viracon – 1 product
• PPG - 1 product
• Guardian – 1 product
• New requirements will force designers and energy consultants to either• Take performance path for the envelope OR
• Lower Window to Wall ratio (WWR)
