The Role and Disruptive Impact of Wireless Lighting Controls - Presented by B...Cindy Foster-Warthen
Lighting Controls play a key role esp. in connection with the new changing energy standards. Traditional and wired systems are often outside clients budgets. Wireless systems are emerging offering affordable accessible, often DIY controls. There are different wireless systems and protocols ranging from Zigbee to JenNetIP as well as mixed systems. We would like to give an overview on how they work, outline technological pro and cons, describe new functionalities and highlight how they go beyond the traditional lighting manufacturer approach. In addition many new personalized controls come to market in connection with the SmartHome. Lighting Controls are now accessible, affordable for everyone and not just for the high-end market. We like to give an overview over the current emerging systems and how they differ from legacy systems.

LED Light Quality: Achieving natural dimming performance without flicker - Pr...Cindy Foster-Warthen
During this sessions, we will review the functions of components that make up an LED system, discover what characteristics of LED systems are required to achieve natural dimming performance, learn about what technologies are used to dim LEDs, define flicker, its causes and effects, learn how to mitigate the effects and understand how to reduce LED anomalies and assure desired performance.
Solid state lighting control is a critical component of many lighting designs. The variety of possible control approaches can be confusing and a bit overwhelming. The goal of this presentation is to demystify the control vocabulary and provide a better understanding of the positive and negative attributes of each of the various approaches to solid state dimming. The concept is to have a role play situation, with a lighting designer and a controls rep discussing best approaches to various applications. The rep will be assisted by a ventriloquist dummy - everytime the rep uses tech speak to explain something, the dummy will translate it into very understandable language.

While light levels may be objectively measured, how we perceive light is entirely subjective. Light affects us on a primal emotional level. On a biological level, our brains are hardwired for long nights huddled around camp fires. More than just cycles of light and dark, color temperatures tied to the sun’s appearance at high noon and sunrise/sunset play a central role in regulating our body’s biochemistry. How light affects us changes throughout the course of our lives, can be culturally dependent and is ultimately, entirely personal. In order to illicit the desired emotional response, a lighting designer needs to be able to make choices about where, when, and what kind of light to put on any given surface. These choices need to be perfectly reproducible but also flexible and able to adapt to changes in ambient conditions and space usage requirements. This is what a lighting control system does. Designing a lighting control can be hard. Yes, it requires a thorough understanding of the technology, but that is not what makes it hard. What makes it hard is understanding how best to apply the technology within the context of the entirety of the job. What does the system need to be able to do, both now and in the future? How, and by whom, is the system is going to be used on a daily basis? What sort of special events, overrides and/or automatic triggers may help the space achieve the client’s desired level of efficiency? First and foremost, have you guaranteed that someone with no formal training or experience can easily turn on the lights? And what about the budget? It is easy to assume that hard means expensive. While that may be true for certain projects, it is by no means universally true. As I mentioned above, the difficult part is developing the detailed narrative. The actual equipment and installation required may not be very expensive in the scheme of your project. In fact, part of good design involves finding elegant solutions that streamline parts, pieces and installation requirements. A well designed system, tailored for your project and your needs, should cost less than a generic system capable of “doing it all.” Often, after careful analysis, a basic time clock and some presets may be all that a project needs. Make controls parts of your initial design conversation. They may not seem glamorous, but they give life to your design. They are the first thing your client experiences when they enter the space and the last thing they touch when they leave.

LEDs are finally coming into their own: multiple manufacturers have created solutions using tunable white light for architectural applications. However, these solutions are as diverse as the problems they solve. In order for tunable white to be effectively applied in this wide arena of vertical markets we first need to understand the limitations and capabilities of the technologies and controls, as well as the metrics that describe them. We explore first-hand some application examples in the health-care, retail, and art industries with some award-winning lighting designers to help understand that the best fit may be not be a "one-size fits all". Or is it?

Summary:
1. LED Lighting is evolving requiring new solutions that can support the latest generations of LEDs on the market
2. Topology choices are evolving to improve efficiency and reduce overall system cost
3. Intelligent control can enhance energy saving and extend operation lifetime even if more complex drivers are needed to support
4. We have only begun to harness what is possible with Solid State General Lighting
The Government Construction Strategy was published by the Cabinet Office in 2011, announcing that all centrally procured contracts should be compliant with BIM by 2016. The key objective of this approach is to reduce the capital cost and the carbon burden from the construction and operation of the built environment by a fifth. So how should a lighting engineer tackle building a digital street lighting information model?

Code Dread: Keeping up with ASHRAE and LEEDScott Bowman
Design firms will be in the best position to meet their clients’ needs by understanding and preparing for ASHRAE 90.1-2010 and LEED v4, both of which have evolved from their earlier versions and will have major impacts on buildings in the very near future.
This presentation will illustrate the effect of these changes by applying the new standards to an existing LEED Silver-certified project constructed in 2008 by KJWW Engineering Consultants using ASHRAE 90.1-2004.
First, a new baseline using the ASHRAE 90.1-2007 standard will be applied to the project, which is the requirement under LEED v2009. Next, a baseline for the project using ASHRAE 90.1-2010 will be applied to the project, which represents the requirements under LEED v4. Both comparisons will show the decrease in energy savings, points awarded, and strategies and cost required to bring the project back to the original energy savings and the LEED certification it might attain.
The project’s real-life, existing energy performance will be presented as an overlay to all of the comparisons.
Jeff Boldt of KJWW presents ASHRAE 90.1, The Big Picture. Jeff is a member of the 90.1 Mechanical Sub-Committee. Presented at the 2008 ASHRAE Region VI CRC in Chicago, Illinois.

Evaluating Lighting Controls - Results from the Next Generation Luminaries D...Cindy Foster-Warthen
As lighting controls are perhaps the fastest moving aspect of lighting technology, this presentation discusses the recent evaluations of LED luminaires and lighting controls completed by the Next Generation Luminaires Design Competition. Unlike previous NGL presentations at LEDucation (and elsewhere), this session focuses on the evaluation of lighting controls, discussing both methodology and results. The presentation will cover NGL evaluations in four areas: (1) quantitative and visual evaluation of luminaires, (2) basic dimming of submitted luminaires using digital protocols, (3) color tuning controls, and (4) connected lighting systems. Objectives for the presentation include: assessing the submission requirements and evaluation methods; comparing results from current and recent competitions; identifying tentative conclusions based on the evaluation results; and highlighting areas for continuing evaluation. Ms. Taylor will be assisted in the presentation by Charles Thompson and Dan Blitzer
In an age where lighting technology is advancing far faster than the metrics used to define them we have a rare opportunity to redefine lighting for the better. In this talk, Paul will dig deep into existing lighting metrics and discuss the impact LED technology is having on them in the marketplace and if they need to change to be more human centric.

Editor's Notes
This presentation is on the Commercial codes and I am going to apologize now – It is text heavy. I figured a resource that you can refer back to may be more important than following the rules of presenting and Power Point. It is obviously going to be technical and informational heavy. I welcome questions throughout so that we can keep the dialogue interesting and hear other voices than my own.
I also want to acknowledge that I don’t really touch on ComCheck or showing compliance in this presentation. Anne Cheney and Marty Salzberg did a great presentation last year on energy codes and included great explanation of ComCheck. I highly recommend referring to that presentation.
So what will we do today? I will update what codes are being used now in NYS and NYC. I will explain major lighting related changes on IECC from 2009 to 2012 and on Standard 90.1 from 2007 to 2010. Then I will explain what amendments NYS and NYC made on top of the codes for projects here.
You may recognize these books and references. You can file them away.
The state has not updated the Residential code. It may happen this summer. May be effective August 2015? End of Year?
This is also another reason for the Commercial focus of this presentation.
So we have officially updated to the new base codes for commercial projects in NYS and NYC. They are officially supplement documents that reference the new codes and make some amendments. The base reference codes are IECC 2012 and Standard 90.1 2010 as the alternate path.
Here is where you can reference the required documents.
The state link has links to purchase and / or download all needed reference documents and to download the State Supplement.
The city link has full text version of the state code – IECC 2012 with all state and city amendments. A very useful reference. I have not found a way to print or save this document, but I am sure there is a way.
As of today, there are no printed versions of incorporated texts. This is mostly a copyright issue. I have heard rumors that NYSERDA may take this on, but just rumors. And I don’t know if this would be free or for purchase.
The city link has a lot of good resources and look at the FAQ area regularly – there should be some good and needed code interpretations here.
Effective on 1/1/15
So here we go.
What do you need to know?
I will definitely be focusing on what is listed here, but thought I would get the important items out now and will also repeat this at the end. If there are particular areas of concern, you can see what I will be covering in more detail throughout the presentation.
One over-arching note is that IECC is getting closer and closer to being very close to Standard 90.1. For all disciplines including lighting.
LPD’s did decrease, but nothing earth shattering.
IECC Space by Space is back, but there is no decorative allowance.
However if IECC is your chosen path, you have a new chapter that may apply called Additional Efficiency Package Options. This is an important item to pay attention to later.
Of note for alteration type projects that IECC may be much less stringent.
NYS amendments to be aware of
For the most part, there is nothing too scary here – mostly general improvements to language and clarifications on exterior lighting controls, how to count wattages for track and busway and dwelling unit language.
The items on 90.1 are of note and listen for the explanation in just a few slides.
NYC amendments to be aware of.
Dwelling unit item is critical and new for Standard 90.1 projects. Dwelling units within building over 3 stories have to comply.
And the city has revised the language in both codes on occupancy and vacancy sensors.
Ok, so hopefully after seeing these 3 slides, you are still with me and want to stay to hear the gory code language and details.
Before we get to the details, I think everyone is aware there are multiple compliance path options. You have prescriptive, performance which are energy models or cost analysis, and environmental trade off in both codes. However, NYC does not allow for the IECC Performance path. NYS does, but NYC does not.
The next slides will review updates to both codes focusing on lighting related items. We will also review some other trades and administrative code language that effects what lighting designers do first. This is the general format of the slides. IECC and 90.1 are shown side by side and new or important requirements are shown.
Mandatory requirements mean you have to do this no matter what and no matter what compliance path. If you are doing an energy model, you have to do it. And if you are following the prescriptive path, you have to do it. A caveat here is that when energy modeling, it means your base building will have the code provision included and your design building will have the code provision included. There is no energy benefit to mandatory requirements because it all base case.
A prescriptive requirement means you only have to do it when following prescriptive paths.
Boxes will appear if NYS or NYC applied an amendment.
I want to note a few envelope and power requirements that affect lighting or you should understand.
The architect will need to show compliance with this, but the prescriptive requirements for the window to wall ratio is something lighting designers should be aware of and also see that codes are pushing for more spaces that utilize daylight and controlling the electric light near windows when you have more windows.
You should avoid the prescriptive IECC 30% threshold, or else…
Daylighting opportunities are lost when the WWR falls below 40%.
Many LEED projects are using this path because energy modeling is required, so your project may be doing this anyway.
There are certain space and project types that require skylights when following the prescriptive path. Again, more for the architect and may not affect many NYC project types, but good to see the push for daylight from skylights in certain spaces. It is fairly logical where this is applied and spaces are the same in both codes.
Space types that require skylights that meet the requirements above for height and square footage include offices, lobby, atrium, concourse, corridor, storage, gym, convention center, service, manufacturing, retail, warehouse, transportation, workshop.
So here is the first power requirement that the electrical engineer will have to contend with and has to do with voltage drop across feeders and branch circuits, but isn’t easy and may force IECC path for projects.
The National Electric Code has similar requirements that engineers are used to, but at least allows you to combine for a max of 5%. Standard 90.1 missed this and it is my understanding this is hard to do in NYC high rises and I am seeing many engineers request IECC path because of this requirement.
BUT NYS made this prescriptive! Affects projects that are doing energy modeling and you if are doing the model, you can show energy savings elsewhere. If ComCheck/prescriptive – you will have to do this..
This is the other power requirement of note and another cumbersome one for the engineers in addition to added costs for the project.
The automatic control of 50% of the receptacles is only required in private and open offices and computer classrooms and may not be to bad for new construction – little added cost.
Does not apply to existing equipment “reuse”. Might not be horrible for alteration type projects, but may have some convincing of the engineer and owner to do.
Yes, this is prescriptive only, but I am not sure how many interior fit out projects that aren’t doing energy modeling this will help.
Now we will get into the Lighting requirements in both codes and state and city amendments. I am mostly reviewing items that have changed from the previous versions of the code. If I don’t mention a requirement, it means it hasn’t changed, but it is still required.
Here is the big news on dwelling units.
IECC just references the IECC residential language and the requirements are good practice and nothing daunting in my opinion. I think the big loop hole is that you don’t have to count low voltage lighting.
High efficacy lamps and fixtures that use those lamps are easy to come by. CFL, T8, T5 and requirements for low wattage lamps.
>50 lumens / watt for between 15 and 40 watt lamp
>40 lumens / watt for <15 watt lamp
The city only – not the state - is requiring that dwelling units within commercial buildings that follow 90.1 also meet the IECC language. High-efficacy lamps are not defined in Standard 90.1, and there is not clarification from the city yet, but we have to assume you can use the IECC definition.
Another quick dwelling unit requirement for IECC only – dwelling units shall have separate meters.
For alternation projects, the thresholds for compliance are different for the two codes. Standard 90.1 used to be 50%!
Of note for NYS and NYC – IECC is much less stringent!
If you are doing lamps+ballasts, consider IECC path.
Standard 90.1, If you are just doing lamps or just ballasts – does not have to meet alteration requirements
Now we are into the big items. The major changes related to lighting are additional mandatory control requirements and many more automatic controls. Many slides will be on occupancy, vacancy and daylight responsive controls. We always worry about LPD’s and this is still important, but there are little changes to the LPD limits in both codes as I noted earlier. So here we go with a lot of control requirements first.
Both codes require automatic controls – time switches or occupancy sensors basically – to turn the lights off when the space is unoccupied or closed.
Independent manual lighting controls are required in each space for both codes. And then each space also requires a reduction.
The exceptions for the light reduction in Standard 90.1 include corridors, lobbies, restrooms, stairways.
IECC has similar exceptions for the light reduction and also includes spaces with occupancy sensors, sleeping units and spaces complying with the daylight section. AND rooms with LPD< .6 w/sq ft
These are the reference code requirements for occupancy sensors. As you can see – many more spaces require a mandatory occupancy sensor. They have to turn the lights off after 30 min of no occupancy.
There is some interesting items regarding manual on and auto on. If you turn the fixtures on automatically, they can only come to 50% power or alternate switching, etc. In certain space types 100% on is ok.
Standard 90.1 - Exceptions include spaces with multi-scene systems, shop and lab classrooms, safety, 24 hour operation
IECC has similar exceptions and also includes spaces with occupancy sensors, sleeping units and spaces complying with the daylight section.
BUT NYC has completely re-written this.
This is the NYC code language that replaces the IECC and 90.1 language in both of their entireties. This slide not split in half. This is the full language.
I know there is a lot on the slide and it will take some time to read through. Bottom line is that the city prefers manual on. The space types it is required in is logical and makes sense. If you are doing automatic-on, fixtures can only come to 50% power except in corridors, stairs, restrooms, entries, lobbies and spaces that would have a safety issue. Any manual on space is ok to come on to 100%.
Now for Daylight responsive controls.
You need to control daylight zones - both by sidelighting / windows and by skylights and this is done manually or automatically in IECC and automatically in 90.1. Automatic controls require stepped dimming or continuous dimming.
Standard 90.1 exempts retail areas AND where the top of existing adjacent structures block the daylight.
Standard 90.1 – no manual daylight responsive controls allowed.
Needs to be able to dim continuous to 35% lighting power.
OR 3 multi-levels (at least) with 100%, between 50 and 70%, and <35%
IECC language is a bit confusing about daylight responsive controls. Bottom line is that automatic controls are generally not required, buy may if building exceeds 30% WWR or large spaces with mandatory skylights.
Since NY state made this prescriptive, it means that when you are completing energy models, you can take the energy savings from sidelighting and design them into your building and compare it to the base case which won’t have these provisions. You will see in the state supplement that the state has provided daylighting set points for energy modeling.
So what are the daylight zones?
Look in definitions for clear explanations and this diagram may be better.
These are plans. And a bit misleading since the boxes look to be about the same depth from the window. But the WH is rarely going to be 15’, Standard 90.1 is more appropriate and works with the building appropriately. IECC is arbitrary.
Again, look at definitions. I realize that skylights may not be the most common occurrence for projects in this area, but still good to see how they determine the area lit by skylights to determine the controlled zone.
Maybe it is good that skylights are not a common occurrence as you look at this diagram. It isn’t hard – just some fun geometry to figure out.
Even more addition interior controls
There is little change here – you need separate controls for these specific applications that I think we should all be used to.
However, Standard 90.1 has also added a stairwell requirement when they are unoccupied. There is an exemption for life-safety lighting from the code, but it is unclear if you overlight your egress stairs to 10 footcandles, if you would have to reduce the additional lighting that is not meeting the life safety requirements. The IALD Energy and Sustainability Committee has reached out to the 90.1 Lighting Subcommittee to get some clarifications on egress and emergency lighting vs. the energy code. In the mean time, hopefully DOB will address this on their web site.
And now on to exterior lighting controls.
IECC has kept it fairly simple – turn the lights off during the day.
Standard 90.1 is more stringent and wants façade and landscape lighting off for certain hours and the remaining lighting to be set back. It also includes signage.
But the state has made an amendment and we have to follow Standard 90.1 language.
Here is a nice diagram showing Standard 90.1 and thus NYS and NYC requirements.
Believe it or not, Standard 90.1 is addressing controls in parking garages. Automatic reduction controls and automatic daylighting controls at perimeters areas are now required only for Standard 90.1.
This is a bit cumbersome, I’ll warn you. If you have a parking garage and can’t meet the requirements, IECC does not address controls in parking garages.
There are commissioning and Functional Testing requirements in both codes.
I am sorry that I don’t have a good background to present on these new requirements. Reading them it sounds fairly straightforward and was difficult to summarize on a slide. The language has a focus on confirmation of sensors and time switch controls and programmable items.
Also testing of controls – devices, systems, settings, calibrations is now required. Needs to be called out in construction documents. Generally good practice and what is required should be happening anyway to ensure everything is operating properly. DOB has been doing this and I recommend going to their web site to see how they have set this up. We also expect some updates to the FAQ section of the DOB website.
Qualifications of personnel, how DOB will handle it. 90.1 says they have to be someone independent of project, but IECC only says this if required by the code official.
For some reason IECC has left the tandem wiring requirement in the 2012 code. Standard 90.1 finally eliminated it. But the state took care of it for us. So for NYS and NYC projects – any path, no longer required.
Now we have arrived at the Lighting Power Density Tables.
IECC has brought back the space by space table and the values include decorative lighting in certain space types. But there is an explicit decorative allowance that there is in Standard 90.1 that is definitely more flexible.
Standard 90.1 also has increased allowances for tall and unique shaped rooms.
Exemptions for a few space types differ in the codes. IECC exempts professional sports arena playing fields, and hotel guestrooms which is a bit confusing – sleeping units are listed as exempt, but there is a LPD limit.
NY state changes a bit around in how wattage is calculated, but ultimately there is no change in the way watts are determined for track, low voltage, etc.
A few more notes on LPD’s in Standard 90.1 only. There are some additional allowances for certain control methods. So the application of continuous dimming will get you some extra wattage allowances. This also helps with energy modeling when you are following the prescriptive path.
There is an exterior building grounds lighting requirement that is legacy in IECC that still shows – just a basic efficiency requirement before they got the general time clock controls in the code. It is removed from IECC 2015. NY State took care of it now.
Exterior Lighting Power Densities are also of course addressed. Exterior Lighting Power allowances are basically the same for both codes. Standard 90 has changed since Addendum l for the 2007 code which came out in 2008. This is the table with tradable and non-tradable areas and you should be used to it.
Standard 90.1 has a few more lighting application types that are exempt – swimming pools and water features to name two.
LZ0 in Standard 90.1 has basically no allowances, but here to match other codes, LEED, MLO, etc. IECC 2015 will have it too.
Just reviewing Exit Sign requirements – same for both codes
I have saved the best for last.
The Additional Efficiency Package Options section is mandatory – you have to do one of three options. Two options definitely cost more, but HVAC may not be too much of a stretch depending on the project, equipment. However, in the view of many, I am sure people will assume the lighting option is easy and no costs. However, it will be a challenge – you have to use the building area type table and you have to 15% under the values.
In ComCheck, if you select IECC 2012 and alteration, these requirements go away, so it seems to imply that this requirement only applies to New Construction. However, the code language does not specifically say this. I would love an education in the definition of New Construction vs. Alternate for a tenant fit-out project, but I don’t think we can debate that today.
What did you learn?
LPD’s did decrease, but nothing earth shattering. And if you’ve been having good luck with even some LED solutions – it should be easy to achieve.
IECC Space by Space is back, but there is no decorative allowance. IECC’s tables have higher LPD’s than Standard 90.1 because they have accounted for decorative fixtures in certain space types.
However if IECC is your chosen path, you may be stuck with 15% under the Building Area method table because of the wonderful Additional Efficiency Package Options.
Of note for alteration type projects and the two different thresholds.
NYS amendments to be aware of
Nothing huge here, most improves or simplifies language. Remember the power requirements that are prescriptive rather than mandatory.
NYC amendments to be aware of.
Dwelling Units item is critical. The occupancy and vacancy sensor language for NYC projects.
And just one last time with our favorite new requirement – the additional efficiency package options. I wish us all luck.
