NATURAL LIGHT & VIEWS


Why is natural light important to students?NATURAL LIGHT & VIEWS

Improved natural light in schools has been shown to:

• reduce disruption to Circadian Rhythm

• increases test scores

• decreases near-sightedness

• keeps students alert


Strategies for Increasing Daylit Area

Sloped, highly-re�ective ceiling brings daylight into the building reducing energy use

Ultra high-ef�ciency light �xture w/daylight dimming

Light-re�ecting walls

High windows and 85% re�ective light shelf to bounce light deep into the classroom

Extensive daylight transmission through highly transparent glass

Heat-mirror shading keeps heat out in the summer

Triple glazing w/argon improves thermal performance

visible light

Windows located near corners reduce dark areas

More annual sun exposure

Less annual sun exposure


The suns behavior is site and time specific • the sun is higher in the sky in the summer and lower in winter

• the sun moves through the southern sky

• there is more northern exposure in the summer than the winter

Spacial Daylight Autonomy

Spacial Daylight Autonomy - a model simulation that projects the percentage of time during a given period that a point receives the specified illuminance.

Given period - September-June, 7am - 4pm (school year)Specified illuminance - 30 foot candles (recommended classroom light level)

Why is reducing glare Important?NATURAL LIGHT & VIEWS

Excessive solar glare:

• interferes with technology screens and marker-boards making reading from them difficult

• is distracting and uncomfortable, affecting students ability to take in information.

• causes headaches and eye pain with prolonged exposure

Access to Exterior Views

Visual connections to exterior views:

• can reduce absenteeism

• can increase patience and increased task enthusiasm

• provide rest for eyes which is useful when long amounts of time are spent looking at screens.
