the Energy Efficiency
Standards for Residential and
Nonresidential Buildings were
established in 1978—
response to a legislative
mandate to reduce California's
energy consumption
new standards were adopted
by the Commission in 2005
and again in 2010

3. kitchen lighting—title 24
energy efficiency standards are important
and necessary for California’s energy future:
•reduces energy costs
•increases reliability and availability of
electricity
•improves building occupant comfort
•reduces impacts to the environment

4. kitchen lighting—title 24
the Energy Commission adopted the 2008
Standards on April 23, 2008
• approved for publication on Sept, 2008
• effective date for the 2008 Standards was changed
from Aug. 1, 2009 to Jan. 1, 2010
if building permit submitted on or after January 1,
2010, the 2008 Standards must be met
new standards may be coming to us via updated
CalGreen code July, 2013

5. kitchen lighting—title 24
changes in 2001 (following the electricity
crisis) reduced electricity demand by about
150 megawatts (MW) each year
the 2005 standards were expected to reduce
electric demand by another 180 MW each
year—have saved more than $56 billion in
electricity and natural gas costs since 1978
It is estimated the standards will save an
additional $23 billion by 2013

6. kitchen lighting—title 24
changes to the standards occur periodically
to account for improvements in:
•conservation technologies
•cost of fuels
•energy-conserving strategies
•improved capabilities in analyzing building
energy performance
modifications are also made to further
improve compliance and enforcement

7. kitchen lighting—title 24
mandatory measures require:
•minimum ceiling, wall, and raised floor insulation
•minimum HVAC (heating, ventilating and air
conditioning) and water heating equipment
efficiencies
•other requirements—lighting standards

8. kitchen lighting—title 24
documentation of the California Building
Code is required to be submitted prior to
issuing building permits
•new residential building
•adding new conditioned floor area to an
existing building

9. kitchen lighting—title 24
•originally first switch in the kitchen must be
fluorescent
•efficiency of at least 40 lumens per watt
•50% wattage MUST be fluorescent

10. kitchen lighting—title 24

11. kitchen lighting—title 24
2008 residential lighting requirements divide
the home into 3 distinct zones
• ZONE 1—kitchen
• ZONE 2—bathrooms, garages, laundry
rooms and utility rooms
• ZONE 3—hallways, dining rooms, family
rooms, home office and bedrooms
each zone is treated distinctly different

12. kitchen lighting—title 24
retains 50% rule—50% total kitchen lighting
watts must be high efficacy (compact
fluorescent, LED, linear fluorescent)
NEW:
up to 20 watts of low or high efficacy lighting
per linear foot of illuminated cabinet (inside)
vs.

have become the new centers for entertaining—
more casual way of entertaining
trend toward more open house plans—newly
defined space is often called a “great room”

14. kitchen lighting
this impacts lighting design—kitchen should now be
as inviting as the rest of the house
remember light layers!
•under-cabinet lighting
•general illumination
•accent lighting

15. kitchen lighting

16. under-cabinet lighting
first step toward successful light layering—mounted
below the wall cabinets
provides an even level of illumination along
countertops—between your head and the work
surface to cut down on shadows

18. under-cabinet lighting
come in a variety of styles and lamp sources
mounted toward the front of the cabinet, project a
portion of the light toward backsplash

19. under-cabinet lighting
mounted at the back of the cabinet, light can hit
people directly in the eye if they are sitting down

20. under-cabinet lighting
often faced with the challenge of highly reflective
counter surfaces—black granite or glossy tile
choose a reflector that points light to backsplash

21. under-cabinet lighting
what if backsplash is shiny too?
talk to clients first—choose one matte finish

22. general illumination—pendants

23. general illumination—pendants

24. general illumination—linear

25. general illumination—cove lighting

26. general illumination—wall sconces

27. general illumination—skylights
•great source during the day
•best are made of white opal acrylic or fitted with
diffusing material
•at night, light
sources can be
mounted within
skylight to produce
adequate light

28. accent lighting
ceiling height…natural light…work surfaces
affect the placement or amount of light used
many other facets affect it as well:
•color
•reflectance
•texture
•mood
•sloped ceilings
•code
•windows
•tone
•pot racks
•door swings

29. accent lighting
color—
darker finished surfaces absorb more light
an all white kitchen requires dramatically less light
(40-50%) than a kitchen with dark wood cabinets
and walls
reflectance—
highly polished countertop (or other surface) has a
high degree of reflectance—acts as a mirror

30. accent lighting
texture—
you may choose to show off textural quality of
surfaces (brick or stucco)
direct light at an acute angle onto textured
surface—light too far away will smooth out walls

31. accent lighting

32. accent lighting
mood—
remember flow from kitchen to dining to living
room—kitchen should be just as inviting as rest of
house
ambient light softens shadows and creates a warm
glow
tone—
make a color temperature choice that works well
with skin tones and room colors

33. accent lighting

34. accent lighting
code—
title 24
today many decorative luminaires are made to take
compact fluorescents that have dimming
capabilities
windows—
let in wonderful light during the day
become black holes at night unless consideration is
given to exterior lighting

35. accent lighting

36. accent lighting
sloped ceilings—
select special recessed luminaires that don’t cause
glare
some are made especially
for sloped ceilings while
others have a 90-degree
aiming capability

37. accent lighting
pot racks—
extremely difficult to light a work surface through
cookware
consider installing
recessed adjustable
luminaires to cross-
illuminate the counter
surface—increase
amount of ambient light
to diminish shadows

38. accent lighting
door swings—
make sure light switches
are on the unhinged side
of a door
make sure you are
informed of swing
changes that occur
during construction

participation activity
title 24 fluorescent fixtures
…using the handout with suggested lighting
companies, research companies that produce
lighting fixtures in your preferred style that
comply with Title 24
… compile information sheets for each of your
chosen pieces that includes image, finish,
features, dimensions & the website address for
future use
