Residential Lighting

Scope of 2008 Residential Lighting Standards

Applies to:

New construction

Additions

Alterations

Replacement fixtures, not replacement of lamps in fixture




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)




2008 Standards divide home into 4 zones

Different rules for each zone


50% Rule

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
High Efficacy
New allowances

50% rule remains
No limit to kitchen lighting watts

5 New Ventilation Requirements

ASHRAE 62.2-2007
•Requirements for local ventilation (bathrooms/kitchens)
•100 cfm range hoods/50 cfm for bath fan

•Why? Windows not being used for ventilation

•All low-rise residential buildings required to
have whole house ventilation
8
•Window operation not a permissible method

•Mandatory measure


Ventilation


ASHRAE 62.2-2007 scope:
•Kitchens/bathrooms have local exhaust vented to
outdoors
•Clothes dryer vented to outdoors
•Combustion appliances properly vented and air systems
designed to prevent backdrafting
•MERV 6 filters in HVAC system
•Additions smaller than 1000 sq. ft. exempt
8
•Ventilation fans must meet sound requirements
Continuously operation: 1.0 sone
Intermittent fans: 3.0 sone


Ventilation

Ventilation


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
8
"sensed". One sone is the equivalent of a quiet refrigerator.

First proposed by Stanley Smith Stevens in 1936.


Ventilation


•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 & 8
openings between garage and house sealed


Ventilation


Back drafting problems

8


Ventilation


Back drafting solutions

8


Ventilation


•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,8crawl spaces, garages, utility rooms, attics are
generally not habitable spaces


Ventilation


•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
8
area.

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


Ventilation


ASHRAE 62.2-2007

2 areas of concern:

Local ventilation requirements

Whole building mechanical ventilation requirements
8


Ventilation


ASHRAE 62.2-2007


Each kitchen and bathroom must have local exhaust
Can use individual exhaust fans or…
Exhaust system that serves multiple rooms
8


Ventilation


ASHRAE 62.2-2007


Kitchen:

Minimum of 100 cfm for kitchen range hood exhaust

Can also use a ceiling or wall mounted exhaust fan for
8
kitchen but must supply at least 5 air changes of the
kitchen volume per hour


Ventilation


ASHRAE 62.2-2007


Kitchen:
Re-circulating range hoods do not satisfy AHSRAE 62.2
requirements of local exhaust regardless of filtration method

Can be used but in addition to room exhaust for kitchen

Ventilation


ASHRAE 62.2-2007


Kitchen:

Example: 12’ x 14’ kitchen with 10 foot ceiling.
What size ceiling fan is required?
8
Answer: Kitchen volume is 12’x 14’ x 10’ = 1680 cubic feet
5 air changes per hour converts to an airflow rate per
minute as follows:


Ventilation


ASHRAE 62.2-2007


Kitchen:

1680 cubic feet of air x 5 air changes per hour = 8,400 cubic feet
per hour
8
8,400 cubic feet divided by 60 minutes in an hour = 140 cfm

Your choice:
Either 100 cfm for range hood or 140 cfm for ceiling/wall exhaust

8


Ventilation


ASHRAE 62.2-2007

Question: (Pop Quiz)
What is the required continuous ventilation rate required for
a 3 bedroom, 1,800 sq. ft. townhouse?

Formula:
One cubic foot per minute (cfm) for each 100 sq. ft. of floor
area plus87.5 cfm for each occupant. The number of
occupants = the number of bedrooms plus one person:


Ventilation


ASHRAE 62.2-2007

Question:
What is the required continuous ventilation rate required for
a 3 bedroom, 1,800 sq. ft. townhouse?

Answer:
48 cfm. 1800/100 = 18 cfm
8
+ 3 (bedrooms) + 1 (person) x 7.5 cfm = 30 cfm
30 cfm + 18 cfm = 48 cfm


Ventilation


ASHRAE 62.2-2007

Question:
How would you satisfy this 48 cfm ventilation requirement?

8


Ventilation


ASHRAE 62.2-2007

Question:
How would you satisfy the 48 cfm ventilation requirement?

Answer:
50 cfm continuously operating local exhaust
in one of the bathrooms
This also is the minimum cfm required for the local exhaust
portion of ASHRAE 62.2


Ventilation


ASHRAE 62.2-2007

Intermittently operating fans will be required to have a
larger cfm airflow to makeup for the fewer hours of fan
operation.
Required air flow rate can be 10 to 20 times greater when
fans operate less than 6 hours per day.

Minimum8requirement that fan run at least 1 hour in 12


Ventilation


ASHRAE 62.2-2007
Intermittent fan flow rate calculation

8


Ventilation


ASHRAE 62.2-2007

Example

Required ventilation rate is 50 cfm

Ventilation fan runs 80% of the time

What must the airflow rate be?
8


Ventilation


ASHRAE 62.2-2007

Example: 50 cfm fan running 80% of the time

Fractional on-time is .8 (80%)
Ventilation effectiveness (e) is 1

8


Ventilation


ASHRAE 62.2-2007


Ventilation effectiveness (e) is 1

Multiply fractional on-time (.8) by ventilation effectiveness
(1) 0.8 x 1 = 0.8
8
Divide required fan rate by 0.8

50 cfm divided by 0.8 = 63 cfm required


Ventilation


ASHRAE 62.2-2007

Example

Required ventilation rate is 50 cfm

Ventilation fan runs 12 hours per day (50% of the time)

What must the airflow rate be?
8


Ventilation


ASHRAE 62.2-2007


Ventilation effectiveness (e) is 0.5

8


Ventilation


ASHRAE 62.2-2007


Ventilation effectiveness (e) is 0.5

Multiply fractional on-time (.5) by ventilation effectiveness
(1) 0.5 x 0.5 = 0.25
8
Divide required fan rate by 0.25

50 cfm divided by 0.25 = 200 cfm required


Ventilation


ASHRAE 62.2-2007

Calcs
Specs
Details on HVAC plans if incorporated into HVAC system
CF-6R MECH-5 (at inspection)
Who will perform the ventilation calcs? (Title-24 consultant,
8
HVAC designer, architect, etc)
Will need tested airflow of all exhaust fans from manufacturer

Or available at: www.hvi.org


Ventilation


What does this mean for the designer?

8


Ventilation



8


Ventilation



Important!

Must use certified
airflow at 0.25” w.c.

QTR050F appears to
comply but fails using
0.25” w.c. criteria

Must use QTRE080
instead


Ventilation



What does this mean for the inspector?

Note block
Calcs
Specs
CF-6R MECH-5 (at inspection)
Airflow verified in one of two ways:

8
1. Test airflow of system (flow hood) or

2. Certified airflow rating of fan from manufacturer (@ 0.25” w.g.)

3. Also available at: www.hvi.org

Can you interpolate and extrapolate using Table 4-9 ?

8


Ventilation


Title-24 2008 Standards

8


Ventilation



Bottom line:
C.E.C. allows you to interpolate between
columns in table 4-9 but not to extrapolate
beyond columns

For larger airflows than shown on table 4-9
you must using flow hood or flow grid
(larger than 125 cfm)
8


Ventilation



What does this mean for the installer?

Verify minimum duct sizes
Become familiar with table 4-9 (Called table 7.1 in ASHRAE 62.2)

8


Ventilation



Duct sizing using table 4-9

Underlying principles:

1. Larger duct diameter allows longer duct length
2. Smooth ducts perform better than flexible
3. Bends/elbows reduce allowable duct length
4. Duct sizing required for local exhaust (bathrooms and
8
kitchen) and whole house ventilation exhaust


Ventilation




Example:

50 cfm bathroom exhaust requirement (continuous)
Flex duct w/ two “elbows”

What size duct diameter & length will be allowed?
8


Ventilation



Example:

Deduct 15’ of allowable duct length per elbow

8


Ventilation




Example:


50 cfm requires minimum of 4” diameter duct
8
Allowable length is 70 feet
Deduct 30 feet of allowable length (2 elbows x 15 feet ea)
Net allowable length = 40 feet (flex)
Smooth duct allowed length = 105 feet


Ventilation



Verify duct size calculations on CF-6R-MECH-5 with actual duct
installations


Ventilation




Restrictions for multiple exhausts sharing a exhaust duct system

8


Ventilation



Each fan must be equipped with
a backdraft damper

Air exhausted from one
bathroom cannot be allowed to
go into another space

Exhaust fans in multiple dwelling
units may not share a common
duct
8


Ventilation



Can use an in-line centrifugal
fan with switch in each bathroom

Can be used for local exhaust
and whole house ventilation with
timer control

Compliance Forms
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
Installation information gathered to fill out form.

CF-6R Installation Also will need to review CF-1R during bid process to
Certificate determine if any HERS measures will affect their work
CF-4R Field
Verification/HERS 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.

CF-4R Field electronically for registration
Verification/HERS
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


Preparation for 1/1/2010

1 Energy Consultants

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

2 Architects/Designers

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

3 HVAC Contractors

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)

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
