INTD 59 intro to kitchen and bath design
kitchen lighting
kitchen lighting—title 24
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
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
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

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
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
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
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

•originally first switch in the kitchen must be fluorescent•efficiency of at least 40 lumens per watt•50% wattage MUST be fluorescent

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
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)

kitchen lighting
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”
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
kitchen lighting
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
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
under-cabinet lighting
mounted at the back of the cabinet, light can hit people directly in the eye if they are sitting down
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
under-cabinet lighting
what if backsplash is shiny too?
talk to clients first—choose one matte finish
general illumination—pendants
general illumination—pendants
general illumination—linear
general illumination—cove lighting
general illumination—wall sconces
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
accent lighting
ceiling height…natural light…work surfacesaffect the placement or amount of light used
many other facets affect it as well:
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
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
accent lighting
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

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
accent lighting
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
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
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

…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
