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

H M F H A R C H I T E C T S

Strategies for Increasing Daylit Area

Sloped, highly-reflective ceiling brings daylight into the building reducing energy use Ultra high-efficiency light fixture w/daylight dimming Light-reflecting walls High windows and 85% reflective 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

More annual sun exposure Less annual sun exposure

NATURAL LIGHT & VIEWS

The suns behavior is site and time specifjc

• 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) Specifjed 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.
