Q&A 4


Residential Lighting

Scope of 2008 Residential Lighting Standards Applies to: New construction Additions Alterations Replacement fixtures, not replacement of lamps in fixture



Scope of 2008 Residential Lighting Standards Applies only to permanently installed luminaires Portable lighting exempt (plug-in table lamps, floor lamps) Wattage of luminaires only a factor in kitchens Does not apply to luminaires that are integral to appliances (refrigerators, range hoods, garage door openers)



Scope of 2008 Residential Lighting Standards 2008 Standards divide home into 4 zones Different rules for each zone



50% Rule High Efficacy New allowances

#1 Bathrooms, garages, laundry rooms, closets & utility rooms

Minimum efficacy Required controls

#2 All Other Spaces




What is a kitchen? Title-24 Standards define a residential kitchen as “a room or area used for food storage and preparation and washing dishes, including associated counter tops and cabinets, refrigerator, stove, oven and floor areas”



What is a kitchen? “a room or area used for food storage and preparation and washing dishes, including associated counter topes and cabinets, refrigerator, stove, oven and floor areas”



Switching is important! “any other lighting on the same switch as kitchen lighting is also kitchen lighting whether or not the luminaires are in the kitchen area”




50% rule remains No limit to kitchen lighting watts However 50% of total installed lighting watts must be high efficacy High efficacy fixtures switched separately from incandescent or low efficacy fixtures Switches may be mounted on the same faceplate but switched independently




What is high efficacy?




High efficacy fixtures No screw in CF luminaires Must be dedicated, pin-type “Standards do not recognize any adaptor as being able to permanently convert one type of luminaire to another type regardless of manufacturers declarations”




High efficacy fixtures “Electronic Ballasts required for all fluorescent lamps with power rating of 13w or more”




Recessed fixtures in insulated ceilings: Must be zero clearance, IC rated Certified air tight (AT) construction Sealed with gasket or caulk between housing and ceiling




Recessed fixtures in insulated ceilings: Air Tight




Recessed fixtures in insulated ceilings: Label best verified at rough-in If verified at final the inspector may have to remove trim kit to see labels. Not all trim kits are certified airtight. If not must use gasket or caulk. Inspectors may find certified trim kits on non-certified AT fixtures




Recommendations for luminaire specifications To avoid costly change orders: 1. Include all applicable Title-24

lighting requirements in the general notes on the drawings and other bid documents

2. Include Title-24 lighting requirements with each luminaire listed in the lighting schedule text




Recommendations for luminaire specifications:




What is high efficacy? Table 6-2 for LED efficacy




***LED fixtures must be C.E.C. Certified*** Not all LED fixtures are high efficacy




http://www.energy.ca.gov/applicances/database/




What is high efficacy? All fixtures are either: High efficacy or Low efficacy Must be labeled as such on lighting fixture schedule Why?




What is high efficacy? All fixtures are either: High efficacy or Low efficacy 1. Important for kitchen lighting calculations 2. For other rooms it determines control requirements 3. Plancheck requirement




New rules Blank electrical boxes calculated as 180 watts low efficacy (page 6-13 2008 Manual)




New rules Assumed wattage for recessed luminaires (page 6.-15 2008 Manual)




New rules New wattage assumptions for CF or HID fixture that can accommodate a variety of luminaires For example 26w, 32w & 42 watt fixture 26w + 32w + 42w = 100w divided by 3 = 33.33w Or use wattage of largest luminaire initially installed




New allowances 1. Additional low efficacy wattage allowance Only available after 50% efficacy rule met 2. Kitchen has manual on vacancy sensors or dimmers 3. High efficacy luminaires and vacancy sensors in garages, laundry rooms, closets and utility rooms




New allowances Internal cabinet lighting allowance 20 watts per linear foot of illuminated cabinet Must be interior to cabinet and illuminated the inside of cabinet




New allowances Internal cabinet lighting allowance 20 watts per linear foot of illuminated cabinet Can be vertical or horizontal measurement Not both




Question: “I’m adding new lighting fixtures in my existing kitchen, some of the existing fixtures will remain. Will the new fixtures have to be high efficacy?”




Answer: Yes, you will have to install high efficacy new fixtures until you meet the 50% high efficacy level for all the lighting (existing & new) in the kitchen.




Recessed can lighting




Recessed can lighting ICAT label




Recessed can lighting ICAT label Screw-in type = Low-Efficacy




Recessed can lighting




Recessed can lighting ICAT label




Recessed can lighting ICAT label Pin type = High efficacy




Recessed can lighting ICAT label LED type = High efficacy if C.E.C. Certified LED Fixture

ASHRAE 62.2-2007 What is a sone? A Sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the sone value, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed". One sone is the equivalent of a quiet refrigerator. First proposed by Stanley Smith Stevens in 1936.


Ventilation


8

ASHRAE 62.2-2007 scope: •Ventilation air must come from out of doors, not transferred from adjacent dwelling units, garages or crawlspaces

•Combustion appliances properly vented and steps taken to prevent back drafting

•Walls & openings between garage and house sealed

ASHRAE 62.2-2007 scope: •Habitable rooms have windows with ventilation area of at least 4% of floor area for that room (but no less than 5 square feet)

•Habitable rooms include living rooms, family rooms, bedrooms, kitchens.

•Closets, crawl spaces, garages, utility rooms, attics are generally not habitable spaces


Ventilation


8

ASHRAE 62.2-2007 scope: •Openings do not have to be provided by windows

•Can also be operable, insulated, weatherstripped panels

•Can by skylights, thru-wall inlets

•Standards mandate that the openable area of the window, not the size of the entire window unit be 4% of the floor area.

•These requirements are different from egress requirements for Health and Safety Code

Compliance Forms

CF-6R Installation Certificate CF-4R Field Verification/HERS

Installation

CF-6R bottom line: CF-6R forms a major part of Title-24 compliance now. The real “teeth” in the new code. Contractors need to be familiar with CF-6R forms and have information gathered to fill out form. Also will need to review CF-1R during bid process to determine if any HERS measures will affect their work Will require coordination between Designer, Title-24 consultant and HERS raters CF-6R forms filled out by hand will be unwieldy because of requirements to file electronically Will need a system to provide documentation package to inspector, HERS rater, & homeowner & registry if necessary Homeowner receives CF-1R,CF-6R, CF-4R, operation & maintenance information for all features and devices.

Registration

Implications: If registration required building department will require registered copies of CF-1R , CF-6R, and CF-4R that display their unique registration number Contractors may not be set up to submit their CF-6R forms electronically for registration Can use services of HERS raters to facilitate transmittal of CF-6R to registry. However contractor is responsible for content of CF-6R and must sign. HERS rater cannot certify information on a CF-6R form. The days of filling out CF-6R on the hood of contractors work truck are basically over Good communication and record keeping critical Use time left to put into place filing system/record keeping system

Registration


Preparation for 1/1/2010

Energy Consultants 1

Download Standards, Manual, Appendixes http://www.energy.ca.gov/title24/2008standards/index.html Attend training seminars for approved software Develop record keeping procedure for registration requirement


Preparation for 1/1/2010

Architects/Designers 2

Set up drawing files to include note blocks for all lighting fixtures Set up note blocks for ASHRAE 62.2 requirements Even though CF-6R-LTG-1 form isn’t required to be submitted until inspection, you’ll need to be familiar with the rules and calculations in order to design & spec a lighting system that will comply


Preparation for ASHRAE 62.2

HVAC Contractors 3

If you have ducts that run thru a garage be prepared to perform rough-in duct testing (4% leakage) and later a HERS rater will need to verify with a 6% duct test. This is a mandatory ASHRAE 62.2 requirement Become familiar with CF-6R-MECH-5 form and airflow calculation methods Become familiar with fan controls that satisfy requirements of ASHRAE 62.2 (timers with overrides) Will need system for providing owner with instructions on proper operation of ventilation system Be alert to backdraft issues resulting from large, commercial grade exhaust hoods in kitchens Be prepared to fill out and send CF-6R-MECH-5 forms electronically. No longer practical to fill these forms out by hand



Building Officials 4

Download Standards, Manual, Appendixes http://www.energy.ca.gov/title24/2008standards/index.html Download copy of ASHRAE 62.2-2007 http://www.webstore.ansi.org Understand which documents required at plan-check and which are required at inspection (CF-6R-LTG-1, CF-6R-MECH-5) Forms are much more data intensive. Get familiar with new layout of forms and all the data that is now required. Address wet signature verses electronic signature issue ahead of time. Be aware of difference between ASHRAE 62.2 requirement for duct testing verses normal duct testing as a Title-24 credit. (ducts or furnace in garage) Training on ASHRAE 62.2 highly recommended. Become familiar with ventilation calculation methods fan/control features that satisfy this requirement. Important for on-site building inspector, not at plancheck.
