Resources The codes we have discussed today are Energy Codes and

Equipment Codes.

Now lets discuss how we can design to meet the quality and quantity

of light needed by the end user in a sustainable manner and meet

code requirements.

In this portion of the course we will:

Look at several resources available

Compare and determine what should be used if there are

inconsistencies Importance of quality recommendations in additional to quantity

Horizontal illuminance vs. vertical illuminance when is vertical

illuminance important

Review applications that meet all the criteria

Lighting for the Aging Eye

RP-28-07 Lighting and

the visual environmentfor senior living

In 2030, 23% of the USpopulation will be 65 years

or older

Typical age of occupantsin assisted living is 80-85

years today


30/46

Lighting for the Aging EyeSenior LivingLess light reaches the retina at age70 only 1/3 of that for the 25 year old

Dark adaptation requiresincreased time

Lighting for the Aging EyeSenior Living

Color of light Effects on yellowed lens

Effects on Dementia patients

Effects on Alzheimers

patients Location of light fixtures

may need to be different

need to maintain a bright

and constant level of light

Daylight may help or harm

visibility shades or blinds

a must

Lighting Design is morechallenging than most

applications to meet all

needs

Visual impairment variesbut affects 19% over 70 &

much higher % in seniors

in assisted living centers

Loss of Contrast in visual

How can we achieve the light levels and lighting qualitywhile meeting the energy codes?

ASHRAE/IES 90.1-2010 Exemption (9.22.3 G):

Lighting in spaces specifically designed for use by

occupants with special lighting needs including visual

impairment and other medical and age related issues

In CA OSHPD trumps Title 24 for Health Care applications

Title 24 allows 1.5 w/sf can be achieved using energy

efficient sources and light fixtures.

This was the most

controversial topic in thedevelopment of exterior

energy codes and the

driving force.

Code issues how to reduce

luminance and light trespass

Lighting for Exteriors - More changesLuminaire Classification from RP-33-99

FULL CUTOFF is best forreducing light pollution

but CUTOFF may produce a more

energy efficient parking lot design

Codes can be met with

traditional sources (metal

halide or HPS) or newer

(LED, plasma, electrodeless)

Most projects today consider

solid state lighting (SSL-

LED)

Caution potential of

increased glare if luminaire is

not well designed

LEDs are more directional

Shoebox is well developed

and potential is flashpoints

-Design Resources-

In summary, there are many resources available and industry standardsare important to review for information and legal protection :

IES Handbook 10th Edition the Latest ANSI/IES Recommended Practices compare with handbook for

illuminance levels; criteria & needs should still be current Goal forthese is update every 5 years

IES Design Guides Additional information when an RP doesnt coverthe topic

ASHRAE/IES/AIA Standards and Design Guides on specific topicsthat will address needs for all aspects of the building (AEDG 30% freeonline; 50% now for purchase)

ALG Advanced Lighting Guidelines all online now for regularcontent updates. Uses industry specialists for authors. Someinformation is free; more detailed information requires subscription.
