IDL - Bozeman eNEWS - April 2013 - Vol. 6 No. 4


NAIC LEED Charrette, Recent Projects, and New Location!

     The Integrated Design Lab has been busy in Bozeman the past few months.  Since our last eNews we have moved back home into Cheever Hall from our offices in Romney Gym on the MSU campus.  Our new location is 121 Cheever Hall, near the craft shop on the west end of the building [Figure 1].  We always welcome visitors curious about the daylighting and energy work in the lab.  Please contact us if you wish to learn more.

      Over the past few months we have been working on quite a few projects around Montana.  The projects have ranged in scale from five stage hotel and dormitory housing in Yellowstone National Park to a bank lobby in Billings, Montana.  In conjunction with Mosaic Architecture and Kath Williams + Associates of Bozeman, we performed LEED Daylight and Views verification on the Old Faithful Housing project for Xanterra Parks & Resorts, Inc. in Yellowstone National Park.  This project met the daylight and views requirements with nearly over 95% of spaces meeting the qualifications.  Of particular importance to the success of this project are the short north-south cross section with living spaces put towards the perimeter, while the service portions of the program were placed on the interior [Figure 2].

     On the other end of the scale, the IDL also provided daylighting and electric lighting analysis for the Valley Federal Credit Union in Billings, Montana.  The Billings VFCU project for High Plains Architects examined the potential of various skylight monitor options to bring adequate daylighting into the lobby space of this 1980s era building.  Through multiple iterations of design ideas presented by High Plains and the IDL, we determined a best option.  The lab then reviewed several electric lighting design choices provided by High Plains.  The IDL then made recommendations on fixture types and layouts given our simulations [Figure 3].  This project was great for the IDL because it allowed us to closely work with the architect to test a matrix of options that resulted in the most efficient design given the spatial conditions.

     In conjunction with Kath Williams + Associates of Bozeman and ZGF Architects of Portland, Oregon, and the MSU USGBC Student Chapter, the IDL will be participating in the schematic design LEED Charrette for the new Norm Asbjornson Innovation Center [NAIC].  This charrette will be a chance for the MSU community stakeholders to learn about and voice their opinions for which credits the NAIC should pursue as part of the design ethic.  Public input is highly valued in this integrated design process, and all of the sponsoring organizations welcome any who would like to join.  The Charrette is this Wednesday, February 25, from 9 am to 4 pm on the third floor of the MSU Bobcat Stadium.  Participants can feel free to come and go as they please throughout the day.  For more information visit the website www.msuinnovationcenter.com.  We hope to see you there!

Daylighting and LEED v4: What this means for design and allied professionals

As of July 2013 the USGBC voting body overwhelmingly approved the new LEED v4 rating system.  In November the new rating system will be launched at the Greenbuild Conference in Philadelphia.  Introducing the system will be Scot Horst, Vice-President of LEED at the USGBC.  At the conference LEED will present updated v4 exam information, reference guides, and educational resources.  More information about the conference and its schedule can be found on the Greenbuild website listed below.  With change there comes dire speculation about how the new rating system will be implemented.  Beginning in November, LEED v4 and LEED 2009 will concurrently accept applications for project certification.  LEED 2009 will accept applications until June 1, 2015, at which time LEED v4 will become the exclusive certification rating system.  Most importantly, however, the major question most design professionals and members of the allied professions are asking themselves is, “What does this mean for me?”  In response the Bozeman Integrated Design Lab is examining the new Daylighting credit structure.  Provided is a basic summary of what has changed in the Daylighting credit for those professionals seeking LEED v4 certified projects.


The changes to the daylighting credit are, for the most part, relatively simple.  Most obviously is that the daylighting and view credits previously known as IEQ Credit 8.1: Daylight and Views-Daylight, has become simply EQ Credit: Daylight.  “Views” is now a separate credit.  Within this v4 credit, there are a few structural changes.  First, the illuminance units have been switched from the English unit “footcandles” (fc) to the SI-unit “lux”.  Additionally, the acceptable illuminance value range has been narrowed to 300-3000 lux (approximately 28 fc to 280 fc).  Another important change is the elimination of “Option 2. Prescriptive” as a choice for the verification of daylighting values.  This option has been replaced by a new simulation called “Spatial Daylight Autonomy and Annual Sunlight Exposure.”  Spatial daylight autonomy (sDA) is a standard requiring 50% of occupiable hours during the year be adequately daylit in a project (between 300-3000 lux).  The caveat, however, is controlling Annual Sunlight Exposure (ASE), which is the percentage of square footage in regularly occupied spaces that has direct sunlight during the year.  LEED v4 will require that illuminance values of 1000 lux and above must not exceed 250 occupied hours during the year, and must not exist in more than 10% of the occupiable floor area.  Occupiable hours will be typically considered between 8 a.m. and 6 p.m.  Two points can be gained if the sDA value is achievable in 55% of regularly occupied space, and three points can be gained if the sDA value is achievable in 75% of occupied space.  The hierarchy of points has been carried through to the other two traditional LEED 2009 verification options: “Illuminance Calculations” and “Measurement.” 


While these changes are topical, they will certainly require familiarization.  In order to help mitigate confusion, Figure 1.illustrates some of the new terminology in the daylighting credit, and Figure 2.breaks down the new hierarchy of points.  The Integrated Design Lab in Bozeman is committed to aiding design and allied professionals understand the possibilities for designing with daylight regardless of LEED certification.  However, the lab welcomes your questions and advice on the new LEED v4 rating system.  In future e-news sections, the lab will be addressing changes to the views credit in v4 as well as following up on information that emerges from v4’s implementation.




Spatial Daylight Autonomy

     LEED v4 Abbreviation: sDA 300, 50%

*Standard that requires 50% of occupiable hours during the year be adequately daylit


*In the LEED v4 abbreviation “sDA 300, 50%” the “300” is the lux value and the “50%” percentage of occupiable hours.  Therefore sDA 300 lux, 50% of occupiable hours

Annual Sunlight Exposure

     LEED v4 Abbreviation: ASE 1000, 250

*Standard that requires regularly occupied spaces to not have too much direct sunlight, which causes glare and can increase cooling loads


*In the LEED v4 abbreviation “ASE 1000, 250” the “1000” is the lux value considered direct sunlight and the “250” is the maximum number of occupiable hours direct sunlight can be present in an area.  Therefore ASE 1000 lux, 250 hours

MSU USGBC, AIA Montana, Montana Society of Engineers, Oh My!


Students from the Montana State University School of Architecture in cooperation with students from the College of Engineering have announced the establishment of a MSU Chapter of the USGBC.  The establishment of this chapter is in an effort to provide professional development and networking opportunities to students not only in architecture and engineering, but in the allied professions as well.  The new organization plans to develop a brown bag lunch lecture series geared towards exploring the experiences of architects, engineers, and allied professionals’ with LEED and their projects developed under the standards.  Training courses are currently being developed to prepare participants for the LEED Green Associate exam.  Additionally, the chapter will focus on developing and implementing LEED oriented goals for facilities on the MSU campus.

The first meeting will be on September 16th at a location to be determined.  For more information about participating as a student, lecturer, or general resource contact Agnes Pohl at agnespohl@gmail.com.
