1. INTD 59 intro to kitchen and bath design kitchen lighting

2. 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

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 http://www.energy.ca.gov/title24/2008standards/

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. 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.

13. 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”

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

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. 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. 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. 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

39. kitchen lighting—title 24 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
