Wavelengths of Light

UV C = 200- 280 nm UV B = 280 - 315 nm UV A = 315 - 400 nm

Visible Light = 400 nm - 700 nm



Positive Effect or Hazard of Light?

•Spectrum [Wavelength] absorbed •Spectrum [Wavelength] emitted •Chromophores present •Time of Day •Direction of the Light emitted •Intensity •Mechanism

Laws of Photobiology An Action Spectrum is a parameter that

describes the relative effectiveness of energy at different wavelengths in producing a particular biological response.



Action Spectrum for Circadian Rhythm

Area under the curve from 460 - 500 nm




Laws of Photobiology When measuring the effectiveness of a light source to produce a biological effect you must use the appropriate instruments.

Circadian Rhythm

hormonal changes

pineal – sleep/wake

pituitary – growth, blood pressure,

reproduction

adrenal – stress

thyroid – metabolism



Previous Measurements for Circadian Responses – Not Reproducible

Numerous studies published in medical journals have examined the

influence of circadian dysfunction

on sleep, dementia, increased risk of breast and prostate cancer, obesity and diabetes without a specific definition of light used!!!!

“Bright light” is the most common adjective, although at times “lux”

unique effect Intensity- Bright is not a sufficient descriptor Lux is insufficient for Circadian Effects Timing- Daily,Monthly,Seasonal Duration- Microseconds, Hours Direction- Reflective v direct

The WELL Building Standard®

International WELL Building Institute

!IWBI launched by Delos as part of Clinton Global Initiative Commitment in 2013

!Goal of sharing WELL Building Standard

!Two-stage Scientific and Technical Review process “It will literally change the way we live…designing spaces to solve health problems before they're created.”

FORMER PRESIDENT BILL CLINTON

The WELL Building Standard was announced as a commitment to the Clinton Global Initiative by Delos, a Wellness Real Estate tm and technology company, on September 24th, 2012. Pursuant to this commitment, Delos formed the IWBI in 2013 to administer and share the WELL Building Standard globally.

Daylight Quality – Health

Daylighting in buildings improves health and well-being by:

• Increasing the connection to the outdoors

• Providing views to vegetation and nature

• Providing access to light that is dynamic

and gives clues to the human body

Daylight Quality - Views

Daylight Quality – Recharge and Refresh Daylight Quality – Balanced Daylight

Daylighting Strategies – Color, Reflectivity and Materials Daylighting Strategies – Sidelighting

Research shows access to quality daylight improves:

• Productivity

• Visual Comfort

• Mood/morale

• Health and Circadian Rhythm


Daylighting Strategies – Toplighting

Daylight can play an integral role in the lighting strategy and activation of a space, even from

above:

• Toplighting via clerestory glazing can provide full spectrum daylight to enhance a space while indicating time of day without views

Daylighting Strategies – Toplighting

Daylighting Strategies – Borrowed Daylight

Allowing daylight to penetrate across spaces from sidelighting or toplighting can provide a

unique connection to the sky that can benefit interior spaces that may not have direct access to daylight
