    Part of the buzz last week at the GANA Annual Conference was how giddy everyone was for the recent defeat of the ASHRAE 189.1 proposal to lower window to wall ratios to 30 percent from the existing 40-percent standard.  Victory in the “Battle for the Wall” (as the outgoing Guardian president Scott Thomsen called it last year at BEC) means we get to keep a fourth of the glass, windows, and walls we all like to sell. People were saying at GANA that “25 percent of everyone’s business has just been saved.”  A big thank you, again, to the glass manufacturers for helping take the lead on this for all of us.

    The flip side, of course, is that everyone still has their guard up, trying to decipher where the next fight is coming from. Some of the talk at the GANA receptions focused on what we all can do together to change to a pro-active stance in which the industry leads more, versus reacting to what other organizations are doing. I don’t know where I heard it, maybe it was Texas:  As an industry, our position could change to: “Have to get going, we’re busy, we have things to do, and people to do them to!”  That would be a great stance for GANA to take, leading that is, and doing it politely, of course.

    Two presentations last week highlighted how fundamentally flawed the ASHRAE proposals were: one from Carnegie Mellon and one from MIT.  Since so much attention is being paid to energy within the architecture schools, you might have an excellent source already in your backyard that you can invite to AIA or your local glass association to talk about daylighting and WWRs, or to stay in touch with continuing education seminar/webinar/courses they may be offering.  Granted, the credit might not be worth anything as far as keeping professional registrations current within your firm, but isn’t that worth the cost if there’s something to be learned?

    These particular presentations included everything from computer modeling of daylighting levels within any given space to shading of framing systems.  If GANA posts them, you will see some of the shots fired across ASHRAE’s bow in saving 25 percent of our biz.

    Julie Schimmelpenningh from Eastman gave an excellent presentation about how to upgrade existing school entrances to make it harder for potential shooters to gain entry, and there’s not really a whole lot that has to be done, contrary to what you may be thinking.  The stats say that a majority of these events are over within six minutes of starting.  So delaying tactics, along with other measures, regardless the form, gains precious time for first responders to get there to protect children and teachers, thus potentially saving more lives.

    Julie has agreed to give the presentation at BEC next month. You‘ll have to come early as her presentation will be during the Technical Committee on Sunday, March 16, 3-5 p.m. It will be in conjunction with two other presentations that hopefully will draw your attention:

    • Jim Benney is going to talk about the CMA for NFRC Certification.  He made a presentation in Orlando about some of the problems in getting the spectral and diffuse data into NFRC’s database for translucent glass, frits or interlayers.  This also is related to why sloped glazing and spandrel glass hasn’t made its way into the NFRC formulas for certification.  Some funding issues with furthering development of the CMA with respect to these products have arisen, and I’ll let you think on where that may lead.  Monitoring what’s going on with NFRC is important as much of the data for framing, glass and spacers now on the market are not in the NFRC database.  If NFRC certification ever takes off, either as a code or spec requirement that IS enforced, this will affect much more than 25 percent of your business.
    • Jon McFarland at Wheaton Sprague is going to talk how his firm is helping glazing subs with their BIM modeling requirements.  This is not a “how do you do BIM?” but rather, Jon will show representative samples of BIM projects and the pickups his firm’s clients are getting from its use. Within BEC, we haven’t done anything about setting glass industry standards regarding BIM, but the follow-up conversations after his presentation could change that thinking.

    If you can’t tell, I was stoked by the whole Annual Conference experience! Except for one conclusion I came away with:  more BEC people need to attend. Everything discussed at the meeting trickles down to BEC: all the groups, (Protective Glazing Council, Tempering, Laminating, Insulating Glass, even Decorative, etc.), as well as all the developing or updating of standards, all the product designations, limitations, specifications. The BEC companies use it all:  they prepare estimates using these standards and products, they sell it to their customers with every contract they sign, and then have to be conversant enough with the standards to make the GCs and architects understand it and get “buy-ins.”  The output of these types of industry conferences, due to the diligence and interest of the people who have contributed year-in and year-out, have benefited your business to no end. It’s not right that more BEC people aren’t in the room affecting the decisions.

    In that light, there was also a discussion about rejoining the annual conference with BEC, as it had been in the past. Initially, I was not for this. But, by the end of the conference, seeing what’s getting done and not having more BEC people there, I withdraw my objections for now, if it gives a better shot for BEC representatives to participate in the GANA end.

    One last note: the awards for division contributors of the year and recognition of Carol Land’s impending retirement were in stark contrast to the tribute paid to Greg Carney. It is an understatement to say it was moving and touching. From that, one of my aspirations is to be one of his “glassholes.” It won’t be the same if he can’t lay that one on, but, it’s worth a shot.

    Other takes from last week to follow in the next post. And, please, someone remind me next year to bring duct tape to the annual meeting, and to put it to good use! Hint: you had to be there on Thursday in the Insulating Glass Division.

    The ASHRAE folks keep stirring the pot, and it doesn’t bode well for the glass industry. I’m left wondering: How do they get away with writing proscriptive qualifications for glazing that would result in a black/white reduction in the amount of vision glass in a building, when glazing can be more effectively addressed with a little forethought and integrated design?

    I get that walls, by means of their thermal performance, directly impact the amount of heating and cooling required for a building. It doesn’t matter if the wall is glass, insulating glass, metal panels, stucco, precast or any other material, if heat can travel through it, then the HVAC systems are impacted, and ASHRAE by rights weighs in.

    But, how can they proscribe the amount of glass on a building? This would be like GANA or the precast industry proscribing what the building frames have to be in order to carry the weight and loading of the curtainwall materials being anchored to them, and then professional engineers have to design building structures to those limits. We could require A50 Steel and 5,000 psi concrete, claiming it could reduce the size of embeds and anchors. I know it’s not a well reasoned argument, but neither is ASHRAE’s claim about the need to limit vision glass.

    Besides, did it occur to ASHRAE that more HVAC capacity is required when artificial lighting loads go up? There is a correlation between increasing daylight (read: increasing glass) and reducing the amount of artificial lighting required. How has ASHRAE responded to that? How would the lighting folks respond if they had ASHRAE come in and say, “We want fewer lights, as it reduces the capacity of the HVAC equipment.”

    Limiting vision glass also reduces the human comfort factor of daylighting. That’s sometimes hard to put dollars on, but there are studies about improved productivity of workers and students occupying spaces with abundant natural light.

    One more argument: ASHRAE does not limit the area of the structure that bridges the exterior wall and is exposed to exterior conditions. All those balconies on condos are really just radiator fins. Talk about an ice maker on a cold December day in Chicago.

    Okay, enough crying: Who’s going to save us from the abyss?

    We need the architects to take a stand. An architect friend of mine said he’d be surprised if a lot of architects know what ASHRAE is, let alone what the organization’s proposed standard 90.1 related to glass requires. His office is looking into indigenous architecture for clues on how to design for the location, rather than relying on any one standard. The point is, architects have to design for the whole, and balance all types of needs from human comfort to energy usage, as they relate to HVAC and lighting. One discipline can’t outweigh any of the others. Good design is most evident when all components are molded, kneaded and coalesced into a cohesive whole: Structure, human comfort, circulation, HVAC, exterior walls, all blended together so that no one element takes precedence over the others.

    I see a lot of pleas from industry publications that now’s the time to weigh in. And, I get that. Unfortunately, many of the little guys don’t have the time or resources to devote to this fight. So they look to the industry big boys to carry the fight for them.

    Look at BEC, for example. Sure a lot of the contractors go to Vegas every spring for the BEC conference, but look at the people serving on the BEC committees. There’s a lot of representation from the manufacturers, but not a lot from the CONTRACTORS. It’s because the resources aren’t there. What about the big glazing contractors, can they step it up a bit for the industry?

    I will pass my comments onto ASHRAE. Who else will step up to the plate? Everybody remembers how Mighty Casey ended his day. Let there be joy in Glassville, instead. Hopefully, there are those among us who will not only make a plate appearance, but will smack it outta the park.

    The Glass Association of North America’s (GANA) Building Envelope Contractors (BEC) Conference has come and gone, with some good ground covered. A high point was when Guardian’s Scott Thomsen gave a strong call to action for our industry in his presentation the “Battle for the Wall.”  The key takeaway was if we don’t fight for the role of glass in energy-efficient construction (thermal performance and daylighting), then ASHRAE will force us to the sidelines. Do you want to go to work for the stud wall, stucco and masonry contractors, because ASHRAE’s current emphasis is to greatly downsize the percentage of glass in exterior walls?

    We as a glazing industry should be showing architects  there are many glazing products that WILL increase thermal performance.  Architects will help us win this war, but only if we get smarter about educating them on the newest, most innovative glass and framing products now available.

    We should also be assertive with noting the other construction types have as many problems, as well, that are now coming to light in this energy-conscious age.  As ATI’s John Runkle noted in his presentation on building commissioning, these are things the glazing industry has dealt with for years.

    Notably, when the surrounding wall systems – cavity walls behind masonry or panels, precast panels, or whatever construction –  have to start meeting the same water and air penetration requirements as windows and curtainwall presently do on a regular basis, then that bodes well for the exterior skin, as a whole.

    But there are some down-sides, too.  For example, testing the weatherproofing/air barrier to the AAMA and ASTM standards for water penetration  aren’t  realistic since it never sees that amount of rain in the finished condition if a brick or panel wall is placed over it.  Air test it, yes. But a full-blown, 5-gallon/hour/square-foot water test ON THAT SURFACE isn’t real-world.  Some of this is still in the developmental stage, but I expect it will catch on in one form or another.

    Does commissioning make sense for a total glass curtainwall? Probably not with the current regimen of pre-construction and in-field testing required in curtainwall and window specifications.  There are some that would argue the call for increased testing is an effort by the labs to create more work for themselves.  Yes, I can see that, but what good is it having an air- and water-tight window or curtainwall if the wall around it doesn’t perform equally as well?

    Another high point at BEC was the presentation on Chinese tariffs. Some of the USGNN.com newsfeed had comments from the Chinese manufacturers’ side of the fence that felt the presentation didn’t accurately present both sides of the argument.  That wasn’t likely to occur given the fact the person making the presentation was the plaintiff’s attorney.  When’s the last time a lawyer led a fair, objective and balanced viewpoint on something his clients were paying him to have just the opposite opinion on in order to properly argue their case?  But, the tariff issue is going to be in the news quite a bit going forward.

    One last note:  Having turned the odometer over on my age this year, my brother bought me opening day tickets in Philly next Friday.  And, my no. 1 son bought us Final Four tickets.  Only one drawback to the venue:  basketball was not meant to be played in a football arena, unless they put the court in the end zone.  When watching the game, the Philly Phanatic sitting down the right field line in the KU garb, or in the corner of the end zone in Atlanta with the biggest pair of binoculars known to man will be yours truly.  This is one thing I’ll be able to cross off the ol’ bucket list.  As I review this blog post one last time Monday morning, I hope Wichita can shock the world.

    Here’s hoping the Easter season, with the accompanying onset of spring weather, brings renewal of faith, hope and charity to you and yours.
