This credit promotes efficient, high-performance lighting systems through increased controllability for building occupants. Allowing individuals control over the lighting levels in their workspaces can enhance their comfort, productivity, satisfaction, and overall wellbeing.
Better lighting controls can also increase the efficiency of your lighting system by focusing on task lighting rather than unnecessary ambient lightingLighting in a space that provides for general wayfinding and visual comfort, in contrast to task lighting, which illuminates a defined area to facilitate specific visual work., and can reduce energy use due to cooling loads by allowing occupants to turn off lights when leaving their space or when daylight is sufficient.
The credit requires that you provide individual lighting controls for a minimum of 90% of building occupants, and that all shared, multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations. be equipped with lighting controls.
Task lighting combined with ambient lighting is a common and easy way to achieve this credit.In most buildings, you can satisfy the majority of credit requirements simply by providing an on-off switch for each multi-occupant space and task lighting in individual workspaces—but be aware that standard lighting system design may not allow for adjustments to lighting levels to meet specific, task-related needs.
It’s strongly recommended that you optimize the lighting system design. This could mean a combination of dimmers, occupancy and daylight sensors for multi-occupant spaces, and adjustable task lighting for individually occupied spacesOccupied Spaces are defined as enclosed spaces that can accommodate human activities. Occupied spaces are further classified as regularly occupied or non-regularly occupied spaces based on the duration of the occupancy, individual or multi-occupant based on the quantity of occupants, and densely or non-densely occupied spaces based upon the concentration of occupants in the space.. Take note, however, that dimmers, occupancy sensors and daylight sensors alone do not meet the credit requirements unless they have an override switch.
Establish occupant-use types for each space (individual or multi-occupant), and identify the lighting needs for each space. Review space programming and the requirements to provide lighting controls for both individual and multi-occupant spaces.
Establish lighting control goals and include them in the Basis of Design for EAp1: Fundamental Commissioning.
Providing controllability for occupants does not have to involve a complex lighting system―you can simply provide plug-in task lighting in individual spaces and on-off switches in multi-occupant spaces.
The inclusion of occupancy and daylight sensors can provide a more efficient lighting system, but it does not provide occupants with more controllability. Rather than limiting your project to merely meeting the credit requirements, a combination of lighting controls and lighting controllability is ideal.
Providing lighting controllability to 90% of individual-occupant spaces can add some upfront cost to your project if this is not standard practice. However, better lighting controllability can reduce lighting and cooling loads and increase productivity. Additionally, since ambient lighting generally is more energy-intensive and generates more heat than task lighting, emphasis on task-specific lighting can reduce energy costs by reducing the level of ambient lighting needed.
Begin to lay out the lighting design, individual controls, and control systems. Typically, ambient lighting does not provide all occupants with adequate control. To provide control, design task lighting in addition to ambient lighting.
At a minimum, provide individual controls for 90% of occupants.
Providing individual lighting controllability supports energy efficiency, as the occupants can turn off the lighting system when leaving a space.
An open office space counts as individually occupied when each person has an individual desk and a defined space.
Develop a list of individually occupied and shared multi-occupant spaces. A multi-occupant space is for group interactions―classrooms, conference rooms, cafeterias, lobbies, warehouse loading areas, theaters, break rooms, commercial kitchens, retail stores, and exhibit spaces―where large numbers of people are expected to gather.
When designing, consider lighting controllability in combination with your daylighting strategy. For example, if your project has a good design for daylight, you may want to provide task lighting on the interior walls instead of near windows, or daylight sensors in conjunction with an on-off switch for ambient lighting and task lighting for individuals.
Review opportunities for daylighting, light shelves, skylights, or light tubes. Along with these strategies, consider occupant controls related to each strategy, such as interior or exterior blinds, or changing the aperture on skylights or light tubes. Also consider assessing building orientation and space allocation. These are best practices, not credit requirements.
Although it's not required for credit compliance, providing ambient and individual controls with variable lighting levels is recommended. Also, consider how individual lighting levels could supplement ambient lighting to provide each with variable lighting levels.
Individual control means that there is a switch accessible to each occupant for control over lighting levels at their individual workspace. It can be a task light in an open office scenario, a main-wall sconce in a private office, a ceiling-hung light in living and bedrooms, or a desk light at a reception desk. Keep in mind, though, that in order to count toward the 90% of individually controlled lighting, 90% of occupants must have a dedicated control or task light.
Task lighting does not need to be hardwired in order to meet the credit requirements.
The credit requirements are based on number of occupants for individually occupied spaces and number of spaces for multi-occupant spaces. Only 90% of total building occupants must have controls in individually occupied spaces, but each of the multi-occupant spaces must have independent controls.
Together, the owner and design team should set preliminary lighting goals and incorporate them into the Owner’s Project Requirements (OPR) for building commissioning credits EAp1 and EAc2.
Employ a lighting designer to develop and review specialized lighting design considerations, such as glare and special-use lighting in A/V presentation rooms.
For (a minimum of) 90% of individual occupants, provide lighting that can be easily adjusted by the individual. This can include task lighting that is not hardwired, or hardwired lighting with on-off switches that control lighting at an individual workstation. Individual lighting may not be shared if it is to apply to the credit.
Confirm that 90% of individual lighting controllability is being provided by performing a basic calculation.
For all multi-use spaces, such as conference rooms, adequate controls must be provided to control lighting levels appropriate to programming and space use.
Confirm that 100% of multi-occupant spaces have adequate manual controls.
Examine project space allocation to evaluate whether there are any areas that present a challenge for meeting the requirements, or space programming that makes lighting controls inappropriate for the space.
Ideally, when specifying task or ambient lighting, lighting position should be adjustable and have multiple light levels. However, the credit can be satisfied with lights that simply turn on and off.
All daylight and occupancy controls must have a manual override to count toward the credit requirements. (This refers only to spaces that are applicable to the relevant space types. Non-regularly-occupied spaces such as bathrooms would not apply.)
Residences can meet this requirement with appropriately located, switch-operated plug receptacles. If no hardwired lighting is provided in a space, floor lamps controlled by a switch will still meet the credit requirements.
Include all lighting control locations and specifications in the drawings and bid documents, and develop floor plans indicating the location and type of lighting controls.
Continue to develop your list of occupancy space types and the associated lighting controls.
Include lighting control systems in the commissioning scope of work for the commissioning credits EAp1 and EAc2.
Develop LEED documentation concurrently with or immediately following 100% Construction Documents.
Commission lighting systems to confirm their performance in concert with the commissioning credits EAp1 and EAc2.
Document credit achievement through LEED Online. You'll need to provide the following information:
Calibrate occupancy sensors and other lighting control systems (if included) after the installation of all office equipment and furnishings. Installing office equipment and furnishings after calibrating the lighting control systems could cause poor system performance.
Although not required for credit compliance, developing a plan to monitor the performance of lighting control systems is recommended. This may include occupant survey feedback (EAc5), ongoing monitoring (EAc3), and a schedule for regular testing of components.
Educate the occupants to properly use their controls and to turn them off during hours when the building is unoccupied or the space is not being used.
Ongoing monitoring of system performance will prevent unintended energy use after hours due to faulty sensors and other issues.

Intermixed throughout our open office floor plan, we have included a number of casual seating arrangements to facilitate informal, impromptu meetings. Would these informal seating arrangements be classified as multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations. and therefore require separate lighting controls?
If they are not enclosed and are just comfortable chairs, they probably won't be considered shared multi occupant work areas. In some cases a floor lamp or different lighting can help define these spaces and make them more appealing, but that's a design issue...
I am having trouble translating these systems. Can anyone explain the difference between these 2 control types?
Felipe, I don't know—where are you seeing those terms?
We were just wondering about this, too. In the online template under Table IEQc6.1-1, there is a pull-down menu that allows you to select the "Lighting Control Type." The options are Multiple Mode, Dimmer, Multiple Circuit On/Off, Task Lighting On/Off, and Other. We primarily have occupancy sensors throughout our project, so I'm not sure if that falls under Multiple Mode or Other. I couldn't find anything in the definitions, so any guidance would be helpful. Thanks!
Occupancy Sensors on their own don't count unless they have a manual override. The intent of the credit is to allow users to modify their lighting.
That makes sense. We do have manual overrides, yet I'm still not sure if that counts as a Multiple Mode or Other lighting control type when filling out the template on LEED Online.....
Hi Jill. That's great that you have manual overrides. My sense is that the choice would be the same choice as that which you would choose for a regular on/off switch assuming all occupancy sensors have manual override switches. Hope that helps a bit....I don't have the Letter Template open now so I can't say definitively. It seems that neither Multiple mode or Other would be quite right.
Sounds like multiple mode refers to multiple scene options, e.g. AV, Lectern, Panel Presentation, Whiteboard....
We have been denied IEQc7.1 due to not showing task lighting at each individual workstation. The reason for this is that we have treated the open spaces that include cubicles/ student workstations as multi-occupancy spaces and installed occupancy sensors. Now, in order to match the space designations with IEQc6.2, we cannot list each cubicle as a workstation per the requirements. If we do not list these cubicles on the form, but show the plan with the necessary task lighting at each cubicle, will we be denied again? We are in appeal phase, so I'd rather not do this if someone out there knows it will not work, thanks.
First, just to clarify, I assume you mean EQc6.1 and not EQc7.1?
As you've noted you will need to note each workstation within the open office space as an individual workstation and - as such - you will need to show task lighting for 90% of your workstations. This will need to match the form exactly for EQc6.1. Was EQc6.2 accepted in your original review and did your EQc6.2 show the open office area with individual workstations (warranting individual thermal comfort controls)? If your reviewer accepted that open office area as a multi-occupant space for EQc6.2 but not for EQc6.1 then they are in the wrong and not you. However, if EQc6.2 is already accepted as is then you should be fine for letting that continue as presented to the reviewer. In meeting the reviewer's request for EQc6.1 all that you can do is simply address their specific issue and complaint; it sounds like in this case it is just the issue of having task lights for your cubicles.
Can you help to clarify further and I'll try to help more?
Lauren, I was mistaken, we did not attempt IEQc6.2, but we do not have each cubicle listed as it's own individual workstation, only the private offices. I assume this means that to acheive this point we need to re-designate the spaces with cubicles from mulit-occupant spaces to a whole lot of individual workstations? Thanks.
David. I apologize for the late response. You are correct in your interpretation. I hope it all got figured out.
Our project is following CI-2009 guidelines. What lighting controls would be sufficient for offices with open floor plans? Could a "cluster" (an "island") of 6 tables linked together be considered as one "workspace with individual controls". Would a dimmer that controls a few lamps hanging above that "island" satisfy LEED requirements? What is usually meant by "multiple mode" lighting control? Individual lamps for each table are too expensive for this project. Thank you.
Diana, When you say 6 tables do these 6 tables have 6 people sitting at them? If so, you would need those 6 people to have controllability of their own individual lighting and not just general lighting of the cluster. Does the dimmer allow for a variance in lighting over the 6 tables or does it change them all at once?
If you have 6 tables, but really only 3 people that sit there and rotate in and out depending on the day then I think you can possibly make a case for calling it 3 workstations. It's mostly in how you describe and make your case through your documentation that matters. Reviewers will be looking to see a match between furniture layout and controls. For instance, desks are often an indicator to a reviewer that that desk should have its own control.
Lauren, thank you for your response. Our "cluster" of 6 tables will be occupied by 6 people working on different things at the same time. So, one dimmer that changes lighting all at once cannot be considered sufficient enough control to get this credit. All clear. Thank you again.
No problem, Diana...yes, I think that's right. As I'm sure you're aware, even if you cannot get the point some degree of controllability is always nice to provide.
I have an individually occupied "office" (kind of like a coat-check, really) that for some reason was built with only an occupancy sensor and no wall switch. Does the occupancy sensor count as a lighting control for the occupant?
The intent of the credit is that individuals may want different light levels based on what they are doing, and based on what their individual needs are. Some people need more light to read, some want lower light for AV reasons, and others can read effectively in lower light levels (like my kids do!). So an occupancy sensor doesn't give the individuals the ability to control the lights. In addition, an occ sensor with an override still leaves only two levels - on or off - which LEED reviewers have said in the past is not enough to qualify as "controllability." You may make the argument if it is a perimeter space that an occ sensor override with operable blinds at the windows is offering everyone some adjustability, but I have not seen that successfully argued.
Yeah, I'd suggest making the case that it's not a regularly occupied space. For instance, I don't believe a coat check area is a regularly occupied "office" but I guess I could be missing some details. Is someone sitting at the coat check during running hours? Or, like Jonathan said, I'd adjust the light switches to include manual overrides to help accomplish the requirements. Occupancy sensors help meet goals of energy efficiency but, unfortunately, don't meet the intent of EQc6.1 which is all about controllability for occupants.
Per Jonathan's comment above, I've recently received a reviewer comment that seems to be saying that an occupancy sensor with an a manual override does not meet the requirements of the credit. (Our project incuded "huddle rooms" for 4 people that have occ sensors w manual override and no other controls). We have achieved this credit using this strategy several times before, and I don't see anything in the Reference Guide or elsewhere that says this is unacceptable. Does anyone have thoughts about how I might respond to this?
I am surprised that teams are having trouble with using occupancy sensors with manual override. I've used this path many times for multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations.. Assuming that you're using them for multi-occupant spaces (and not for individual workstations) and assuming that it is clearly described in your narrative that there are manual overrides for the occupancy sensors then I'm not sure why it's not passing.
The RG only states for multi-occupant spaces that you must "provide lighting system controls for all shared multi-occupant spaces to enable adjustments that meet group needs and preferences". I can't see how occupancy sensors with a manual override wouldn't comply with that stated requirement.
Interestingly, under the LEED 2009 IDC RG, includes occupancy sensors under Figure 2 on page 371. Sensors are also included within the Definition section of the credit, on page 372.
Thanks for your quick response, Lauren. I just looked at Figure 2 on p. 371, and the figure itself (in my RG anyway) has an arrow pointing at a dimming switch and labelled: "Control Options: dimmer switches step dimming bi-level switching multi zones" [sic]. Perhaps that is trying to tell me those are my ONLY options! The text below the figure says "a lighting control system that is remotely programmed or uses occupancy sensors to turn lamps on and off can save energy when areas are not in use"... but it doesn't say that occ sensors (or lighting controls) would get us the credit. Perhaps my best bet is to argue inconsistency between this ruling and others we've gotten.
Yeah, my RG says the same thing too. I couldn't find an explicit endorsement of using occupancy sensors. I agree that referencing inconsistencies as well as re-stating the intent of the credit and its requirements should help.
Daylighting is mentioned as a method for meeting the credit requirement of a lighting control. Our project is an open plan with a small number of work stations all within 20 feet of the window. The workstations are in clusters of 4 (8 total people) and there are blinds on the windows. The blinds are about 4 feet wide and there are 6 of them. Can we count each blind as a light control or is there some other method for counting this?
I have never seen a project approach EQc6.1 compliance through the sole use of daylight. I have only seen the use of operable windows for meeting EQc6.2. Daylighting can be part of your overall lighting strategy in that you can reduce your ambient lightingLighting in a space that provides for general wayfinding and visual comfort, in contrast to task lighting, which illuminates a defined area to facilitate specific visual work. levels for spaces if you have task lights and daylight incorporated into your design.
Where in the Reference Guide do you see that daylighting is a means toward compliance? Have others on LEEDuser, tried submitting through blind controls of windows?
How do I go about providing documentation to meet this credit. I am working on a fit out project for a new office. There are roughly 900 cubes with task lighting at each cube, offices with switches/ occupancy sensors and conference rooms with switches / occupancy sensors. Can I upload my electrical engineer's drawings showing all of these things?
We always submit the detail of the furniture showing the task lights in the cubes and lighting drawings with highlighted switches /dimmer switch. Our architectural drawings include the furniture to allow the reviewer to verify the count.
I would show a furniture layout plan and I would upload an electrical plan. If the task lighting is incorporated into the cubicle than I'd upload the cutsheet for that cubicle showing the task light. If the task light is separate, than I'd upload the cut sheet of that separate task light. It sounds like you're in excellent shape for achievement of the credit. Remember that other "individual workstations" beyond cubicles might need to be included such as a receptionist's desk. Also, remember that occupancy sensors do not assist with compliance but simple light switches do. This credits all about the occupants having control over their space.
We submitted a project with several private offices equipped with manual on/off wall switching for the overhead lamps, which was a strategy always accepted on our NCv2.2 projects and was also accepted on a previous CI 2009 project. In our design prelim review, the credit was kicked back noting that the wall switches were not adequate to meet the credit intent. I checked the 2009 reference guide and the language leans towards requiring task lighting (i.e. desk lamps) in all the private offices, without accepting the good old on/off wall switch anymore - has anyone else run into this yet?
We haven't come across this situation in any of our CI projects, yet. It is understood that the wall on/off switch in a private office should suffice the credit requirements as long as the space occupied by only one person. The reference guide does have the suggestion to include task lights for individual controls, but may not be a requirement as a basis of rejecting the credit. I would request a revised review from GBCI with the complete explanation of how each private office is to be occupied by only one person who has full control of the lights in the room. Maybe the detailed narrative will do the trick. Good luck!
Hi Kimberly and Shillpa,
I agree with Shillpa in that, I too, believe that one light switch provided for a private office is sufficient. The reviewer may have misunderstood the context.
The acceptability of on/off switches for private offices has not changed from LEEDv2.2 and LEEDv2009.
Does anyone know if multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations. such as exhibit spaces or lecture rooms without occupant control can be exempted from this credit?
It seems that this credit addresses only the typical office use.
We have a LEED-CI project with several of these highly controlled rooms where we cannot give visitors controls over lighting.
It's true that LEED was originally designed for office spaces and it doesn't always play nicely with other kinds of project types. That being said, I'd take a peek at LEED for Schools because it sounds like you have a similar situation where it makes sense for certain people to have access to controls but not all. For instance, LEED for schools states that classrooms need to provide a lighting system that operates in at least 2 modes: general illumination and A/V. Do your exhibit spaces have multiple control capabilities?
I'd submit a narrative describing the role of these highly controlled rooms and describe how certain indiduals are in charge of the controls. Stress how many control settings exist for the few that can control them.
Documented this for a student center on a college campus where only the facilities personnel - not the students - had access to the lighting controls and there was no problem. There were variable settings via controls.
Per a NCv2.2 CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide ruling (copied below), multi-level overhead lighting is sufficient to meet the EQc6.1 individual control requirement in enclosed offices, in lieu of task lights. The credit requirement has not changed in the 2009 rating systems, but of course the CIR ruling no longer applies. Any word on whether multi-level overhead lighting is an acceptable form of individual control in private offices for 2009 projects?
6/11/2007 - Credit Interpretation Request
Our facility is a college science building with personal office spaces, lecture rooms, and laboratories. The question is in reference to the requirement to provide individual lighting controls for 90% (minimum) of the building occupants. For individual office spaces, does overhead, locally-controlled, multi-level lighting in each individual office meet the requirement to enable adjustment to suit the task needs and preferences?
7/2/2007 - Ruling
The overhead, locally-controlled, multi-level lighting in each individual office meets the definition of individual lighting control as long as the lighting designer declares that this design enables adjustment to suit task needs and preferences.
Yes, multi-level overhead lighting is sufficient to meet the requirements of EQc6.1 for individual offices. Any form of a light control in an individual office would be sufficient; often this is achieved with just one light switch for one office space. It gets a little more tricky if you have a couple employees per office or in an open office work enviornment.
But, one light switch and one office space results in 100% controllability for that space.
In the past we have not had issues with enclosed offices being considered meeting this credit. However, I believe you will see increased emphasis on the fixture light output being adjustable. If the overhead fixtures are simply on/off, that does not appear to meet the intent of the requirement to adjust lighting to meet needs.
Ashrae 90.1 the standard for EA1.1 seems to govern only "permanently installed fixtures". I'm taking that to exclude desk lamps. If so is it kosher to reduce installed lighting to get credits under EA1.1 and provide desk lamps to earn IEQ6.1 without counting them in the LPDLighting power density (LPD) is the amount of electric lighting, usually measured in watts per square foot, being used to illuminate a given space. for EA1.1?
Interestingly enough, this came up recently for one of our projects.
My understanding is that you are correct. It's a little different in California. In CA, I am told that Title-24 2005 requires you to include task lights in your LPDLighting power density (LPD) is the amount of electric lighting, usually measured in watts per square foot, being used to illuminate a given space. calculation.
I think it meets the intent of EAc1.1, in general, to provide a lower LPD with the use of task lights. Page 155 of the LEED-CI Reference Guide actually notes that task lighting may be used to supplement general lighting. On a side note, I think EAc1.4 is intended to address the plug loads but unfortunately only includes equipment and appliances.
While in the past we were able to not include task lighting for some projects, this is no longer the case. Task lighting must be included unless occupancy sensors are provided.
No, Christopher. I have just been denied EA cr1.1 until I provide additional information on all of the "permanently installed" task lighting to be used in the space. Although I would have understood this in order to maintain consistency with EA cr6.1, we did not claim the task lighting under that credit either. So you need to do it either way.
Does it mean that all task lighting that is submitted for IEQ 6.1 should also be included in the LPDLighting power density (LPD) is the amount of electric lighting, usually measured in watts per square foot, being used to illuminate a given space. calculation for EA Cr 1.1 even if it is table lamps (plug load and not fixed task lighting) ?

Achieving IEQc8.1 will affect the lighting system design and may necessitate daylight sensors and shading devices in addition to occupant controls.
This credit addresses and defines multi-occupant spaces in the same way as IEQc6.1.
Optimized lighting systems with occupant controls will likely reduce energy demand while increasing building performance, helping to meet EAp2.
Lighting systems should be included in the commissioning process to confirm optimized performance. This is especially critical for systems that utilize daylight or occupancy sensors.
Lighting system energy should be included in a Measurement and Verification plan. This will help to confirm lighting system performance and energy use attributed to lighting.
