ICC partnership with ASHRAE, AIA, USGBC and IES Means Higher Performing Buildings will be Easier to Achieve

A unified green building code that could become the foundation for LEED certification was created in 2011, thanks to a partnership among ASHRAE, the International Code Council (ICC), the American Institute of Architects (AIA), the Illuminating Engineering Society (IES), and the U.S. Green Building Council (USGBC). That effort got a boost in August 2014, when ICC and ASHRAE agreed to align the technical requirements of ASHRAE’s Standard 189.1 for High Performance Green Buildings (189.1) with ICC’s International Green Construction Code (IgCC) into one single model code.

With that agreement, and with the subsequent definition of each organization’s roles, the ASHRAE Standard 189.1 committee continued revising the standard so it could provide technical content for the IgCC, with the ICC responsible for the administrative sections and publication.

This integrated document, coined the “IgCC powered by 189.1,” will become the 2018 version of the IgCC (2018-IgCC), due to be published in summer 2018.

Eaton’s Bill Johnson on Residential Lighting Trends

I recently had the pleasure of interviewing Bill Johnson, market development manager – Residential Recessed Lighting, Eaton. The topic: residential lighting trends.

I recently had the pleasure of interviewing Bill Johnson, market development manager – Residential Recessed Lighting, Eaton. The topic: residential lighting trends. I’m happy to share his responses with you here. The interview informed an article I wrote for the September 2017 issue of tED Magazine.

DiLouie: What are the major recent trends in single-family residential construction and design, and how are they impacting lighting needs?

Johnson: Many states nationwide have adopted the 2012 and 2015 International Energy Conservation Code (IECC) and California has updated the Title 24 Building Energy Efficiency Code, which are influencing residential lighting.

1) 2015 IECC mandates high-efficacy “lamps” in 75 percent of permanently wired lighting fixtures [50 percent in the 2012 IECC]. Refer to theses IECC mandates for specific language. Therefore under these codes, permanently wired recessed and surface lighting must use a compact fluorescent (CFL) or LED lamp; or an integrated CFL or LED luminaire. In today’s market the LED trend can be found in new home construction and products are readily availability in distribution.

2) 2015 IECC and California Title 24 are both prompting an increased trend in air-leakage testing of the home. The blower testing performed for air leakage of doors and windows also applies to ceiling openings with recessed lighting. That’s because the codes require recessed luminaires to be insulated ceiling (IC)-rated and sealed to limit air leakage between conditioned and unconditioned spaces (when tested in accordance with ASTM E283).

3) California Title 24 eliminated the low-efficacy allowance from previous years, requiring all permanently installed luminaires to be high-efficacy, and screw-base sockets are no longer allowed in recessed luminaires. Additionally, Title 24 and JA8 have set a standard for LED luminaire qualification for color and performance, which in addition to high-efficacy, have propelled the trend in LED lighting as a desirable whole-house solution.

DiLouie: What are the top three major trends in residential lighting design and how are they impacting demand for and development of lighting products?

Johnson: At the outset of LED luminaire development, dimming was integral to the fixture’s functionality. Today dimming and lighting control is evolving into a seamless integration of LED luminaires with holistic control technology.

Wireless control of LED luminaires is now capable from wall devices and app-based platforms that integrate lighting in the connected home world of the Internet of Things.

Color-changing and color tuning technology is making LED even more suited and ultimately more embedded into the lexicon of residential lighting design.

Dim-to-warm is established as an option in LED lamps and integrated LED luminaires where the color temperature shifts from say 3000K to 1850K over the dimming range.

Color tuning is getting attention now that LED luminaires can have embedded wireless technology that allows the freedom of complete control of the light function in color and intensity, and the adjacency of scheduling and security capability from a software app as opposed to a traditional wall controller.

DiLouie: What are the top three major trends in residential lighting product design, and what benefits do they bring to homeowners?

Johnson: The development of surface mounting thin profile flat panel LED luminaires that create wide beam downlight-like illumination and install in a ceiling junction box has created great interest for residential lighting. Surface LEDs are great products, and should be used in conjunction with recessed, under cabinet and decorative luminaires to complete an effective whole-house lighting design.

Small apertures in 2-inch, 3-inch, and 4-inch are growing as a preferred choice due to LED technology advancements. The new generation of LED luminaires can offer higher lumen delivery in smaller apertures, which can match and exceed traditional incandescent/halogen sources. Smaller LED housings are IC rated, which was not possible with incandescent/halogen sources due to elevated thermal test temperatures.

Improvement in smaller, higher output LED arrays along with advances in optical technology such as TIR optics (total internal reflection is a lens and a reflector) now offer varied beam patterns and adjustable functions (tilt/rotation) in directional LED luminaires.

DiLouie: What benefits does LED lighting deliver to homes, and what benefits and impact is it having on living with light?

Johnson: The promise of energy savings with LED lighting over traditional sources is now an expected outcome so the focus of residential lighting can shift back to design in choosing the right light for the occupants, the task, and the visual environment.

Recessed downlighting and under cabinet lighting are key ingredients to residential lighting design in providing a foundation of ambient, accent, and task lighting. Traditionally different embodiments of luminaires with incandescent/halogen lamps provided the right combination of intensity, color and beam control for these types of lighting.

Today’s LED luminaires are meeting these design needs in delivering effective illumination in lumen output, beam distribution and quality, especially the ability to select color temperature or color tuning through controls. So LED luminaires are no longer an energy conservation alternative, but a viable design solution that is accepted in the residential space.

AIA Home Design Trends Survey Finds Growing Popularity of Controls

Wireless features, automated lighting controls, and home automation are becoming more popular in residential projects; the most popular home products demonstrate energy management features. These are just some of the findings from The American Institute of Architects’ (AIA) Home Design Trends Survey covering activity during the second quarter of 2017 that focused on emerging home features, systems and technologies.

Wireless features, automated lighting controls, and home automation are becoming more popular in residential projects; the most popular home products demonstrate energy management features. These are just some of the findings from The American Institute of Architects’ (AIA) Home Design Trends Survey covering activity during the second quarter of 2017 that focused on emerging home features, systems and technologies.

“As more automation products become available, homeowners continue to explore new ways to maintain their spaces with greater ease,” said said AIA Chief Economist, Kermit Baker, PhD, Hon. AIA.

The AIA Home Design Trend Survey is conducted quarterly with a panel of over 500 architecture firms that concentrate their practice in the residential sector. Residential architects are design leaders in shaping how homes function, look, and integrate into communities and this survey helps to identify emerging trends in the housing marketplace. Business conditions are also monitored on a quarterly basis. Future surveys will focus on community design trends (December 2017), and kitchen and bath trends (April 2018).

Most popular spaces

For the sixth consecutive year, outdoor living rooms have taken the top spot in terms of growing consumer interest among special function rooms. Following in second and third for special function rooms are mud rooms and home offices, respectively, as interest in these spaces has seemingly plateaued.

“Prior to the housing downturn, home offices maintained a solid hold as the most requested special function room,” said Baker. “Obviously new home technology offerings have influenced residential design trends, but the impact of the Great Recession can still be seen through homeowner interest in better use of existing space.”

“Not surprisingly demand for greater accessibility features continues to be strong,” Baker added. “Whether it’s a result of generally lower mobility or the aging baby-boomer population, homeowners are preparing for the future.”

Housing market business conditions

  • AIA Home Design Survey Index for Q2 2017 (any score above 50 is positive)
  • Billings: 60
  • Inquiries for new projects: 66 Regional averages: South (64.7), West (63.1), Midwest (58.8), Northeast (48.7)

 

“Activity in the additions and remodeling segments are picking up pace. This is a positive sign for the greater housing market in 2018,” Baker concluded.

DOE Publishes GATEWAY Report on Tunable Lighting in Three Texas Classrooms

The U.S. Department of Energy’s GATEWAY program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.

The U.S. Department of Energy’s GATEWAY program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.

The LED systems were installed in August 2016 and provide the ability to vary the spectral power distribution (SPD) across four preset conditions associated with nominal CCTs of 3000 K, 3500 K, 4200 K, and 5000 K. The controls also provide for preset scenes to vary the on/off status and dimming level of different luminaire zones within the room, to better support such classroom functions as audiovisual presentations.

Among the findings:

• The reduction in input power for the tunable-white LED lighting system was estimated to be 58% relative to the incumbent fluorescent system, and was attributable to the higher efficacy of the LED luminaires and a reduction in illuminances, which previously exceeded IES-recommended levels.
• Dimming furthered the energy savings in each classroom.
• While the teachers’ usage of the controls varied widely as recorded by the monitoring system, in each case the lighting consistently operated with all or some of the luminaires turned off or dimmed for portions of the school day.
• When the control locations were more easily accessed by the teacher, the dimming level was varied more regularly.
• The teachers used the scene controls regularly but used the SPD controls infrequently.
• Color consistency for the tunable-white LED luminaires was very good, even over the dimming range, with only minor variations in CCT and Duv.
• The two teachers interviewed by DOE appreciated the ability to tailor the lighting to different classroom needs, and felt that the lighting and controls allowed the students to be engaged in choosing the settings for various classroom activities. Both teachers stated that the lighting system improved the overall learning environment.

LEDVANCE’s LaSpina on Upgrading Troffers to LED

I recently had the pleasure of interviewing Alfred LaSpina, LED product group marketing manager, LEDVANCE. The topic: options for upgrading fluorescent troffers to LED.

I recently had the pleasure of interviewing Alfred LaSpina, LED product group marketing manager, LEDVANCE. The topic: options for upgrading fluorescent troffers to LED. I’m happy to share his responses with you here. The interview informed an article I wrote for the May 2017 issue of tED Magazine.

DiLouie: What basic choices do building owners have to upgrade existing troffer-based fluorescent lighting systems to LED?

LaSpina: Building owners who want to upgrade existing troffer-based fluorescent lighting systems to LED have two options – using direct lamp replacements with the existing ballast or using retrofit kits which include their own driver and require ballast bypass.

DiLouie: How would you categorize LED troffer/panel products aimed at replacing fluorescent troffers?

LaSpina: LED troffer/panel products aimed at replacing fluorescent troffers can be easy to install, with some troffer retrofit kits done in under 4 minutes. They offer a variety of décor choices, meaning you can maintain the same look or create a new one, both while having the same light quality. These LED solutions can also easily give you dimming functionality and eliminate ballast incompatibility issues.

DiLouie: What are typical energy savings and other advantages of replacing fluorescent troffers with LED troffers/panels?

LaSpina: LED Panels and Troffer Retrofit Kits are energy-saving, environmentally-preferable LED alternatives for retrofitting traditional fluorescent lens troffers with an average energy savings of around 45 – 50 percent and cost savings between $300 – $400 over the lifetime of the product, depending on the existing system. These can also offer building owners the opportunity to change the look of the space if desired.

DiLouie: What are the disadvantages of replacing the troffer with an LED luminaire compared to TLED lamps and retrofit kits?

LaSpina: One of the main disadvantages of replacing a fluorescent troffer with an LED luminaire compared to an LED lamp or retrofit kit is cost, not just the higher initial cost of the luminaire but also labor costs. If you are replacing just the lamps, it can be done quickly and easily by following the instructions. Replacing the whole luminaire requires an electrician as you would need to bypass the existing ballast and wire in the new luminaire.

DiLouie: What are conditions under which replacing the luminaire would be ideal as opposed to replacing the lamps?

LaSpina: Replacing a luminaire would be ideal as opposed to replacing the lamp when you have an aging fixture that has reduced lumen efficacy because the fixture is absorbing more of the light. Replacing the luminaire is also an easy way to jump start the décor of the space and deliver a modern aesthetic. Another reason would be if you have ballasts that are reaching end of life possibly making it more cost effective to replace the entire luminaire.

Depending on the space and light needed there are multiple options including Edge-Lit Panel luminaires with a slim design for tight ceiling spaces or more traditional looking luminaires.

DiLouie: How would you categorize TLED lamps and retrofit kits aimed at replacing fluorescent lamps in fluorescent troffers?

LaSpina: TLED lamp and retrofit kits are energy-saving replacements for fluorescent T12 or T8 lamps with innovative optical and mechanical designs that achieve a light distribution pattern that minimizes lumen loss when installed in fluorescent luminaires.

TLED lamps and retrofit kits are have three UL categories – Type A which are the replacement lamps which offer energy savings and minimal labor costs; Type B are the internal driver lamps that offer low long term maintenance and energy savings; and Type C which are the External Driver lamps (or Retrofit Kits) where you would replace both the lamp and ballast at the same time and typically have a higher LPW and longer life as well as low maintenance. Building owners would need to review their energy, design and budget objectives for the space to decide which option would work best for them.

DiLouie: What are typical energy savings and other advantages of replacing fluorescent lamps with TLED lamps and retrofit kits?

LaSpina: TLED lamps have a long rated life of up to 60,000 hours (L70), reduce energy usage by up to 40 percent, contain no mercury or UV emissions, and provide instant light. Direct replacements for traditional fluorescent T8 lamps with no ballast replacement, like the SYLVANIA SubstiTUBE IPS LED T8 lamps, are plug and play, offer the quickest installation, and don’t require electrical or structural modification of the existing fixture.

LED Troffer Retrofit Kits are energy-saving, environmentally-preferable LED alternatives for retrofitting traditional fluorescent lens troffers with an average energy savings of 49 percent and $329 of the lifetime of the product. The kits also last up to 2 times longer than traditional fluorescent sources. The advantages of replacing fluorescent lamps with an LED troffer retrofit kit are that it utilizes the existing troffer which saves money, bypasses the existing ballast to eliminate ballast compatibility issues, and avoids the need to work above the ceiling. These factors make it an economic and fast replacement option. The best applications for this are existing and new construction settings when you don’t want to change the aesthetics.

DiLouie: What are the disadvantages of replacing the lamps in a fluorescent troffer with TLED lamps instead of replacing the luminaire?

LaSpina: One potential disadvantage of replacing fluorescent lamps with LED lamps instead of replacing the luminaire is the ballast compatibility. Working with a lighting manufacturer that provides an extensive ballast compatibility list for their TLEDs will ensure you have lamps that work with the existing ballasts.

DiLouie: What are conditions under which replacing the lamps with TLED lamps instead of replacing the luminaire would be ideal?

LaSpina: If you are trying to maintain your current look in a space, are looking for a fast and easy installation, have budget restrictions, or are spot relamping in a massive building, TLED lamps are a great option. Our goal is to always find ways to better serve our distributor and contractor customers when they want to replace traditional tube lighting with LED.

DiLouie: What control options exist for TLED lamps and retrofit kits?

LaSpina: TLED lamps can offer 0-10V dimming when using a dimmable ballast, and LED retrofit kits have wireless, 0-10V and phase cut dimming.

DiLouie: If you could tell all electrical distributors just one thing about retrofitting fluorescent troffers to LED, what would it be?

LaSpina: Know the goals of your customer. Are their main priorities energy savings, a new look for the space, or ROI options and total cost of ownership at end of life? This will help you pick the right solution for the application. If you tie it to utility rebates, it is even better for customer.

LED lamps are now being produced with optimized glass optics that mimic the light distribution and looks of traditional lamps. This offers customers the look they’ve come to know with the energy-saving features of LEDs.

LEDVANCE has expanded its award-winning SYLVANIA SubstiTUBE LED product line making it even easier for companies to save money by either replacing traditional tubes to reduce their energy costs or in new construction that want the latest lighting products, in addition to lower labor and recycling costs. SubstiTUBE LED solutions have a long rated life up to 60,000 hours (L70), reduce energy usage by up to 40 percent, contain no mercury or UV emissions, and provide instant light. New additions include a dimmable glass LED T8, a LED T5HO which offers the highest efficacy on the market of its kind, an LED Ubend replacement for traditional fluorescent T8 lamps, and DULUX L LED TT5 lamps. These are ideal for a wide range of applications including general illumination, cove lighting, display cases, parking garages, warehouses and tunnels.

DiLouie: Is there anything else you’d like to add about this topic?

LaSpina: Make sure you are working with a supplier with a proven history of quality and lighting expertise. As more and more startups are pouring LED lamps and retrofit kits into the market, it is easy to be overwhelmed or be tempted to have price be the deciding factor. Take into consideration warranty, quality of service, and commitment to your business.

Inventory control continues to be something to be mindful of in regards to LED products. While you are working with your end users, tie in your sales rep early to work together to make sure your supplier has the right products and qualities at the right time.
