1.
What are the definitions of the following lighting terms?
2.
Do you use these terms in professional practice?
3.
What other lighting terminology do you use on the job?
• Luminous Flux
• Lux
• Footcandle
• Illuminance
• Efficiency
• Efficacy
• CCT
• CRI
TECHNOLOGY OVERVIEW
Luminous flux: rate of flow of visible light emitted from a light source over time, measured in lumens (lm).
Footcandle: equal to one lumen per square foot (1 footcandle = 10 lux).
Illuminance: the amount of luminous flux that covers a surface (measured in lux or footcandles).
Luminous flux is analogous to the flow rate of water, represented by gallons per hour.
TECHNOLOGY OVERVIEW
TECHNOLOGY OVERVIEW
Luminous Intensity: the concentration of light emitted from a given source in a particular direction, measured in candela (cd) (1cd = 1lm per steradian).
*Note: color represents intensity not CCT or CRI
TECHNOLOGY OVERVIEW
Efficiency: the ratio between the useful output of energy and the input of energy.
Luminous Efficacy compares the amount of light produced by a lamp (lumens), to amount of power consumed to produce it (watts).
A high efficacy luminaire provides a large amount of light using little power.
TECHNOLOGY OVERVIEW
Efficiency is usually dimensionless, we compare the lumens exiting a fixture to the lumens produced by the light source.
Efficacy is normally used where input and output units differ. We compare the lumens produced by an amount of wattage.
Which is more efficient?
Efficiency = miles/gallon (energy out, energy in)
Which has a higher efficacy?
Efficacy = fun/gallon
TECHNOLOGY OVERVIEW
Correlated Color Temperature
(CCT)
A specification of the color appearance of light emitted by a lamp, relating its color to the color of light from a source when heated to a particular temperature.
CCT rating for a lamp is a general warmth or coolness measure of its appearance.

Color Rendering Index (CRI)
Color rendering is defined as “Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant” (CIE 17.4–1987)
It is the only color rendering metric with wide spread acceptance
It is calculated by comparing the color appearance of the test source to a reference source for 8 reflective samples (Score from 1–100)
All other aspects of the source for a true comparison should be the same
CRI = 62 CRI = 93
CRI = 80 CRI = 92

TECHNOLOGY OVERVIEW
Efficiency before generation
The CEC has found energy efficiency and demand response as the preferred means of meeting the energy needs of a growing population.
BACKGROUND AND POLICY
2006 – Global Warming Solutions Act (AB 32)
Reduce greenhouse gas emissions to 1990 levels by 2020.
2007 Huffman Bill (AB 1109)
Reduce lighting energy consumption by more than 50% from 2007 residential levels and 25% from 2007 commercial levels by 2018.
The Energy Independence and Security Act of 2007
Eliminates from the market most of the remaining commonly used types of T12 linear fluorescent lamps by July 14, 2012. The magnetic ballasts required to operate those lamps were already phased out beginning July of 2010.
The bill also begins a phase-out of traditional incandescent lamps, establishing a mandated
25% reduction in energy use beginning in January, 2012.
Comprehensive Energy Efficiency Program for Existing Buildings (AB 758)
Requires the California Energy Commission to develop and implement a comprehensive program to achieve greater energy savings in the California’s existing residential and nonresidential building stock. The primary focus of this program is on those buildings that fall significantly below the efficiency required by Title 24.
BACKGROUND AND POLICY
Lighting is the largest electrical load in both homes and businesses, accounting for
35% of commercial annual electricity use and
22% of residential annual use.

New Construction
• Standard incandescent lamps
• Dimming systems
• Occupancy/vacancy Sensors
Existing Buildings
• Approximately 60% of lamps installed in California residences were incandescent lamps
• Advanced lamps* represented about 5% of installed lamps

Reflector CFLs, 3-way CFLs, Bare & covered dimmable CFLs, GU-24 products, EISA-compliant halogens, Advanced incandescents, LEDs
Source 2009 KEMA report: Advanced Lighting Baseline Study BACKGROUND AND POLICY
Highly effective in the long term
2007 survey showed 58% of new residential construction adopted high-efficacy fixtures.
Incorporates efficiency into the building design process
Title 24 mandates a combination of sensors, dimmers and high-efficacy lights during the design stages of construction.
Controls leading the way
2007 survey found that most new residential construction projects have about
10 dimmers per home and that more than 90% of hardwired incandescent fixtures are on dimming systems.
Codes & standards have saved California about $66 billion
For nearly 35 years, the CEC has saved Californians more than $66 billion in energy costs through its standards for energy-efficient buildings and appliances.
These same standards have reduced greenhouse gas emissions by more than
250 million metric tons.
BACKGROUND AND POLICY
The California Energy Commission adopted the 2008 Title 24 Building Energy
Efficiency Standards on April 23, 2008, and the Building Standards Commission approved them for publication on September 11, 2008.
The most recent revision, the 2013 Title 24 Building Energy Efficiency Standards was adopted by the California Energy Commission in May 2012. Any application for a Building Permit submitted on or after January 1, 2014 must meet the
2013 standards.
Research and planning for the
2016 Title 24 Building Energy Efficiency Standards has already begun.
Note: This guide is not intended to be used in lieu of the Title 24 Building Energy Efficiency Standards .
Please visit www.energy.ca.gov/title24 to download the official
Title 24 Building Energy Efficiency Standards as well as the Nonresidential Compliance Manual . To obtain a printed copy of the standards, contact the
California Energy Commission’s publications unit: (916) 654-5200.
BACKGROUND AND POLICY
Title 24 compliance is achievable through two approaches:
Prescriptive Standards
• Simpler, but does not allow as much flexibility in design
• Each individual component of the proposed building must meet a prescribed minimum energy requirement
• Applicant needs only to show that a building meets each minimum or maximum level prescribed in the set of requirements contained in a package
“Which technology is appropriate for my project?”
Performance Standards
• Allows the builder more freedom, but the standards are more complex and involved
• Detailed accounting of energy trade-offs between measures is possible
• Uses CEC-approved computer software to calculate energy tradeoffs based on Title 24 guidelines
“What is available, and how can I piece together the building I want while complying with Title 24?”
BACKGROUND AND POLICY
The following computer programs for energy analysis include all
Alternative Calculation Methods approved by the California Energy
Commission for use in Title 24 2008 certification:
• CALRES 2008 v1.1 ($125–$375)
•
EnergyPro 5.1
($480–$800)
• MICROPAS 8.1 ($795)
Additional details are available at: http://www.energy.ca.gov/title24/2008standards/2008_computer_prog_list.html
BACKGROUND AND POLICY
High-efficacy Luminaires
These lighting fixtures are designed and built to operate only energy-efficient light sources, such as fluorescent T8 lamps, compact fluorescent lamps (CFLs), LEDs and high intensity discharge
(HID) lamps.
Sensors
Occupancy/vacancy sensors and daylight sensors are all devices that automatically turn lights off (or dim them) in response to conditions that they “sense” or “see.”
Dimmers
Dimmers, which are already common in many residential applications, allow room occupants to lower lighting levels (and thus energy use) as desired.
TECHNOLOGY & THE CODE
What is never high efficacy?
• Any luminaire that does not qualify by CEC definition or is not certified to the Commission
• Any luminaire containing medium screw-base socket (E24/E26)

TECHNOLOGY & THE CODE
Specify the appropriate light output
You should be able to “lumen match” the low-efficacy fixtures by specifying systems that use less energy.
Specify the appropriate color
Warmer lamp colors
(CCT 2700-3000K) are the closest match to incandescent.
2013 Update
In the 2013 code, in order to qualify as high efficacy, LED luminaires must be
> 90 CRI and 2700–4000K (indoor) or
2700–5000K (outdoor)
Specify the right lumens/watt ratio
Depending on what lamp wattage is chosen (with the same number of fixtures) you could have a much brighter space or a much darker space in comparison to an existing incandescent space.
For example:
8 (65 watt) BR lamps x 750 lumens
= 7100 lumens
5 (26 watt) CFL lamps x 1300 lumens
=
6500 lumens
10 (13 watt) CFL lamps x 600 lumens
=
6000 lumens

Question:
In stairwells and some corridors,
3-way circuits are a common way to allow control of the lighting from either end of the space. How can I use dimmers to give a similar level of control?
Answer:
In this case, the Standards require that the lighting must be controlled by at least one dimmer. It is functionally preferable to have dimmers at every point. However, the Standards do not require that every control point must allow dimming. One of the switches could be a dimmer and the other could be a regular toggle switch.
Alternatively, more advanced controls are available that allow dimming from both ends of the circuit.
However, the toggles switch(es) must not allow the lighting to come on at a higher level than is set by the dimmer.

Question:
Is it good lighting practice to have all the lighting in a room controlled by a single vacancy sensor?
Answer:
If the sensor can “see” the whole space, then it can be enough.
In rooms where safety is an issue, high-efficacy luminaires should be installed. High-efficacy luminaires do not require a vacancy sensor to meet the Residential Lighting Standards. If a sensor is also used, consider a dual-tech sensor or include a second luminaire that stays on.

Question:
I am designing kitchen lighting for a
2,400-ft 2 house under the 2008 code.
My design exceeds the 50% lowefficacy lighting ratio. This design includes 208W of high-efficacy lighting. I plan to control the lowefficacy lighting in the kitchen with a multi-scene programmable control system and install both high-efficacy lighting and vacancy sensors in the garage, laundry room, all closets greater than 70 ft 2 , and the utility room.
Answer:
You are allowed an additional 50W of low efficacy lighting in the kitchen because the house is less than 2,500 ft 2 . You are also allowed less than or equal to 208W of low-efficacy lighting based upon the watts of high-efficacy lighting you are installing.
50W + 208W = 258W
Therefore, you are allowed to install up to
258W of low-efficacy lighting in the kitchen.
How many watts of low-efficacy lighting can I install in my kitchen?

Question:
I am designing kitchen lighting for a
2,400-ft 2 house under the
2013 code.
My design exceeds the 50% lowefficacy lighting ratio. This design includes 208W of high-efficacy lighting. I plan to control the lowefficacy lighting in the kitchen with a multi-scene programmable control system and install both high-efficacy lighting and vacancy sensors in the garage, laundry room, all closets greater than 70 ft 2 , and the utility room.
Answer:
You are allowed an additional
50W of low efficacy lighting in the kitchen because the house is less than 2,500 ft 2 AND if the kitchen lighting is also connected to vacancy sensors. You are also allowed less than or equal to
208W of low-efficacy lighting based upon the watts of high-efficacy lighting you are installing.
50W + 208W = 258W
Can I still use the bonus wattage of low-efficacy lighting in my kitchen?
What other conditions apply in the new code?
Therefore, you are allowed to install up to 258W of low-efficacy lighting in the kitchen.

Question:
I am installing puck lights under the shelves of cabinets with glass doors.
Some of the lighting will inadvertently spill through the glass.
Answer:
Yes .
This is still considered lighting for the purpose of illuminating the inside of the cabinets because the lighting system is specifically designed for illuminating the inside of the cabinets.
Is this still considered lighting only for the purpose of illuminating the inside of the cabinets?
If a different lighting system, such as adjustable flood lights, is designed to project lighting onto surfaces external to the cabinets, that lighting will be considered permanently installed kitchen lighting and not internal cabinet lighting.

Question:
Is the factory-installed lighting system in a bathroom’s mounted medicine cabinet required to be either highefficacy or controlled by a vacancy sensor?
Answer:
If the factory-installed lighting in a medicine cabinet is designed to only illuminate the inside of the cabinet, and the lighting is controlled only by a door-activated switch, then the factory installed lighting is not regulated by the Residential Lighting
Standards.
If the factory-installed lighting is connected to a manually operated switch, or the lighting is designed to illuminate or display contents of the cabinet when the door is closed, then it is considered permanently installed lighting and must comply with the
Residential Lighting Standards.
LIGHTING DESIGN GUIDE: BATHROOMS
• High efficacy, vacancy sensor, or dimmer
• High-efficacy and low-efficacy light fixtures must be controlled separately
• Vacancy sensors must be manual on/off and automatic off
• Switched outlets (half-hots) do not require special controls
• Ceiling fans with incandescent light kits need one switch for the fan and one dimmer/vacancy sensor for the lights.
• High-efficacy: only one switch is needed, two are shown for flexibility

LIGHTING DESIGN GUIDE: LIVING AND DINING ROOMS
Question:
Can a ceiling fan with integrated lighting be a high-efficacy luminaire?
Answer:
Yes . Ceiling fan light kits with integral
CFL ballasts are available. Some LED lighting may qualify as high efficacy.
Some occupants are likely to prefer obscured lamps to visible lamps.
When the ceiling fan is installed in a room other than a kitchen, bathroom, garage, laundry room and/or utility room, a less efficient alternative is to use incandescent lamps on a dimming circuit separate to the fan circuit .

• Must be high-efficacy, or controlled by a manual on/off switch, motion sensor, and a method automatically turn off lights during daytime
• Low-efficacy outdoor luminaires may have a temporary override switch which bypasses the motion sensing function for up to six hours provided that the override switch automatically reactivates the motion sensor
• Outdoor luminaires in or around swimming pools or water features are exempt from Title 24
• A manual off/on switch (no override to on)
Outdoor Motion Sensors
• Must have automatic on/off operation and photocells to keep lights off during daylight hours
• Must comply with the maximum
30-minute shut-off requirement
• Must view the space that it illuminates
Override Switch
Low-efficacy outdoor luminaires may have a temporary override switch which bypasses the motion sensing function for up to six hours , provided that the override switch automatically reactivates the motion sensor.
LIGHTING DESIGN GUIDE: OUTDOOR LIGHTING
• LEDs are ideal for cold outdoor environment, as CFLs often are not compatible with cold temperatures.
• The lifespan of LEDs are significantly longer than other lamp sources, requiring less maintenance.
• Although not required by the standards when using a high-efficacy fixture, including a motion sensor will provide light to occupants upon entering the space when no immediate access to a switch is available.
• For outdoor areas close to bedroom windows, high-efficacy luminaires are preferred over low-efficacy luminaires with motion sensors that may be triggered in the middle of the night.
LIGHTING DESIGN GUIDE: FRONT PORCH
• Provide adequate lighting to support the function of the space and specific tasks performed within it.
• Although not required by the standards when using a high-efficacy fixture, including a motion sensor (as shown) will provide light to occupants where there is not immediate access to a switch in a transitional space.
• Motion sensor coverage should not be too large, or lights will be triggered by street traffic or a neighbor’s motion. Most sensors have a sensitivity control to adjust the degree of motion and light that triggers them.
• In addition to the motion sensor and one of the three other lighting control options, the owner also must be provided with a manual on/off switch for low-efficacy luminaires.

LIGHTING DESIGN GUIDE: MULTI-FAMILY COMMON AREAS
Design
Architects, engineers and designers must understand both the requirements and the underlying intent of the standards if they are to design buildings and systems that are inherently energy efficient and cost effective.
Permit Application
Design teams must make sure that the plans contain all the information that the building official will need to verify that the building or system satisfies the requirements.
Plan Check
The plans examiner of the local building department must verify that the building or system satisfies the requirements of the standards and that the plans (not just the compliance forms) contain the information to be verified during field inspection.
Construction
Contractors must carefully follow the approved plans and specifications, and the building department field inspector(s) must verify that the building or system is constructed according to the plans and specifications.
Acceptance Commissioning
After completion of construction, the contractor and/or the design team must properly commission the building and its systems and provide information and/or training to the building operators on maintenance and operation of the building and its equipment.
Operation
After occupancy, the building and its systems must be correctly operated and properly maintained.
COMPLIANCE PROCESS
Mandatory measures required by both prescriptive and performance approaches include the following areas:
• Building envelope
• Space conditioning, water heating and plumbing
• Ducts and fans
• Pools and spas
