Today’s Decisions Impact Long-Term Success

No Comments

Allow me to borrow an example from the residential window market for a moment. Talk in the industry has revolved around the critically stringent new ENERGY STAR 7.0 criteria, set to take effect at some point in 2023. Window systems meeting the current criteria will in most cases need to make significant design alterations to achieve the thermal efficiency performance required to maintain the ENERGY STAR label.

The question for window manufacturers is this: How to go about making these changes? There are options, and some of them are more complicated than others. To date, residential manufacturers have typically relied on their insulating glass units to meet previous ENERGY STAR criteria; low-E coatings and high-performance spacer systems have gotten the job done.

But the new ENERGY STAR 7.0 numbers — requiring a < 0.22 u factor and > 0.17 solar heat gain coefficient in the Northern Zone, which covers much of North America — will trigger more dramatic changes. My colleague John Ryba has written extensively about the options manufacturers have at this magazine’s sister publication for the past year. Triple-paned IG could be a necessity if manufacturers don’t want to alter their window systems completely. Elsewhere, switching to energy-efficient vinyl systems can help manufacturers meet the new figures with greater confidence.

The latter process involves a greater upfront investment. Changing your vinyl systems is a big shift — but one that might be worthwhile over the long term for residential manufacturers who want to remain at the forefront of energy efficiency trends in the industry.

What does this have to do with the commercial glass industry? First, it’s important to remember that energy efficiency standards, barring some major regulatory shakeups, never go backward. ENERGY STAR is just one example. Government bodies around the world, from the local level to the national stage, are more concerned than ever with fostering greater sustainability in all areas of society. We’ve seen the effects in North America as new building codes in major municipalities are implemented, demanding higher and higher levels of performance from all types of buildings. That, of course, includes glass and glazing codes.

It means that the case is strong for commercial fabricators (both window and door and glass) to invest in innovative and forward-thinking technology today — before it simply becomes the cost of doing business. For example, high-performance vinyl systems have proven themselves to be viable in commercial window and wall applications, while delivering an outstanding thermal performance that metallic options can’t match without major modifications. Warm-edge spacer systems have likewise delivered outstanding efficiency gains in major commercial applications, including architectural glazing. The right products can also provide nice efficiency improvements in manufacturing.

Technologies like these represent not only a way for commercial fabricators to prepare themselves for a future where more stringent efficiency standards come into effect; they’re also a means to create separation from the competition. As we round out 2022, it’s worth keeping these things in mind while making plans for 2023 and beyond. It’s incumbent upon the commercial glass and glazing industry to remain innovative as codes and regulations change. Investing in high-performance technology is one path to get there.

Color Considerations for Commercial Window Fabricators

No Comments

If you’re in the fenestration industry, and you stay up to date on home décor and design trends, you’re likely aware that colored vinyl windows have made an impact on homes everywhere. Homeowners are looking for darker hues that match modern living spaces — and window frames can make a statement.

But this is a commercial blog. Why are we talking about residential vinyl? There are a few reasons that I’ve been thinking about recently.

The first is because apartment or condominium dwellers have desires too, and builders have taken notice. My colleagues and I have been hearing increasing chatter in recent months about the demand for new color options in multifamily housing and high-rise applications. The second is because commercial-grade vinyl is an ideal choice for applications like the ones I just described for several reasons (as regular readers of this blog know), and it’s an ideal material to pair with an increasingly wide range of available color options.

For commercial window manufacturers, there are a few things to think through as you’re thinking of developing new color options or expanding your current portfolio. Let’s take a look:

Color Quality
Branching into new colors involves evaluating the different technology options that are available to commercial fabricators. Generally, paint and laminate options are the ones most frequently considered when it comes to offering colored windows. However, both methods have their drawbacks. Each needs additional labor on the plant floor (i.e., applying the paint or laminate), and at a time when fabricators are struggling with manpower, such steps can be limiting. Meanwhile, paint and laminate quality is of utmost importance. Lesser materials may be susceptible to longevity issues over time, especially in commercial applications and in most extreme climates.

But advanced color technology available today can solve each of these challenges. Co-extruded color technology, for example, sees that color becomes an integral part of the vinyl profile itself. Such technology delivers significantly enhanced scratch resistance, high durability and the ability to withstand harsh weather conditions seen by commercial windows. It’s an option worth exploring for each of these benefits.

Thermal Efficiency

I’ve written extensively about the performance benefits of select commercial vinyl window systems. In a regulatory environment that’s increasingly concerned with sustainability and stringent demands for commercial buildings, high-performing vinyl window systems can deliver outstanding energy benefits in applications where metallic systems have traditionally held the majority of the market share. The energy benefits can be striking, and these systems have increasingly proved their ability to deliver long-term performance.

Your ability to pair a high-performance commercial window system with high-quality color technology as described earlier can be a powerful differentiator in these types of markets. Think dense metropolitan areas especially, where aesthetic design considerations collide with stringent building code requirements.

Ordering and Availability

One challenge for manufacturers offering multiple color options is the added SKUs doing so involves. For example: Let’s say you offer one commercial profile in four standard color options, but several new project opportunities are requesting additional color options and some dual color configurations. If your supplier can offer these options, it could open new business opportunities, but also lead to added inventory challenges.

From an inventory perspective, things can quickly become complicated. You don’t want to have countless varieties of colored units sitting around in your warehouse, either. And your vinyl supplier won’t be hanging on to all that inventory themselves. A good one, however, can help deliver on your needs in step with your demand with a reasonable lead time. Open these kinds of conversations with your vinyl supplier to ensure you can both stay nimble.

As the commercial construction industry continues to demand more from its fenestration systems, I think that increasingly broad color options represent one way we can continue to innovate. Pairing those options with high levels of performance and efficiency is even better.

Getting in Front of Energy Penalties

No Comments

Can you put a specific price on a building’s energy emissions? In New York City, starting in 2024, you can: $268.

That’s the penalty building owners will be charged for every metric ton of CO2 generated above an established limit beginning in two short years. Local Law 97, passed in 2019, will apply these limits for buildings in excess of 25,000 square feet from 2024–2029 before they become even more stringent (and with harsher penalties) from 2030–2034. While there are some additional complexities to the law—limits vary depending upon the type of building and its current emissions—the message is clear. Inefficiency now comes with a cost, and it can add up quickly.

New York City isn’t the only major city deploying these measures to reduce carbon emissions and promote greater sustainability. Washington, D.C., recently proposed a similar law that would take effect in 2025. Surely other cities aren’t far behind.

These measures are part of a more widespread push toward sustainability, but they strike me as a fairly distinct shift from how the industry has traditionally thought about a building’s efficiency. Energy efficiency is typically framed around the benefits—lower energy bills, occupancy comfort and, yes, reduced emissions. And it’s true that reaping these benefits requires an investment that some building and property owners may have previously not deemed necessarily worthwhile. But major municipalities instituting financial penalties for poorly performing buildings is a new kind of motivator for building owners and managers.

The commercial glass and glazing industry has some opportunity here, because high-performance window and glass systems are a great way to improve a building’s energy efficiency without sacrificing too much of the window-to-wall ratio. And I think this kind of financial imperative to improve energy efficiency in all buildings—new and old—will continue to drive greater acceptance of progressive window technologies.

One example is high-performing vinyl window systems, which can deliver outstanding energy benefits in a variety of applications where metallic systems have traditionally held the majority of market share. Not only are the energy benefits striking (especially when combined with warm-edge spacer systems), but there is also more evidence of their ability to deliver long-term performance. Last month I wrote about project-specific mock-up testing and why it’s becoming increasingly important to help validate the expected energy and structural performance of new, efficient building technologies. Vinyl systems, when installed with the right technique and care, absolutely have the potential to meet and exceed expectations.

For commercial glass professionals, we can advocate for technologies like these for our customers. For building owners in New York City and potentially other major municipalities, it’s decision time—invest in bolstering the efficiency of your properties today, or pay the price tomorrow.
