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.

 

Being Thankful for Progress

No Comments

We’re approaching the end of November, and that means Thanksgiving and the holiday season is right around the corner. I hope that after the challenges our industry has been through this year, you’ll be able to find at least a bit of time to rest and reflect over the next month or so.

With all of this in mind, I got to thinking about what we—the fenestration industry—can or should be thankful for this year. On first thought, it might seem a bit difficult to identify those things as we continue to navigate the ongoing supply chain crunch, labor issues, and additional challenges that arrived with the pandemic and don’t seem to have subsided.

But I was struck by a couple of recent news items in this magazine. A new report from Key Media & Research suggests that commercial glass-related construction is approaching a full rebound. Elsewhere, a panel of commercial construction industry experts recently noted that construction pipelines are full and expect that the market is headed toward a period of sustained growth. You’ve probably been seeing and hearing similar chatter in the past few months.

This is all good news we can be thankful for, and it’s also worth thinking about a little more deeply. It’s evidence not just of the resiliency of our industry, but of commercial glass and glazing’s vital role in the modern built environment. The benefits are real, and they’re in high demand in new construction. Outstanding efficiency and occupancy comfort. Daylighting and views. Long-term performance.

We’ve helped sustain the demand for these benefits by working with building code communities to demonstrate glass’s ability to meet desirable performance targets in large-format glazing and curtainwall applications. We’ve also done it by utilizing proven technologies such as warm-edge spacer systems, low-E coatings, new kinds of framing, and other solutions. Glass today is an essential part of modern facades—and it’s because of the tremendous effort and innovation our industry has delivered over the past few decades. I’m thankful for the progress we’ve made toward the realization of more efficient, modern commercial construction.

It’s worth thinking about this collective hard work and collaboration as we begin to look toward next year and the future beyond. And while for many in the industry it’s been difficult to forecast too far beyond the day-to-day, it’s important that commercial glass professionals don’t let today’s challenges cause us to rest on our laurels. Make no mistake—it’s rough in the world of commercial glass fabrication and installation right now. But demand for what we can bring to modern buildings is higher than it’s ever been, and it will take our continued efforts and innovation to keep driving that demand higher.

Toward the end of a year filled with challenges, I hope you can find some things to be thankful for in the commercial fenestration space. And I’d love to hear what they are—let me know at Joe.Erb@Quanex.com.

Addressing Energy Consumption in Older and Historic Buildings

No Comments

How can you tell if a commercial building is inefficient? In New York City, you’ll now know as soon as you walk through the door.

At the start of this year, a new rule went into effect requiring multifamily, nonresidential and public or government buildings greater than 25,000 square feet to post an A-F letter grade based on the building’s Energy Star score. Late last year, New York magazine took stock of 50 of the most recognizable properties in the city—just four of them received an “A” rating, and the majority fell into the “D” category.

The new system speaks to the urgency with which New York officials are taking on energy efficiency and sustainability, and are just a precursor for what’s on the horizon. Per New York magazine:

If the grades seem harsh, that’s on purpose: They’re intentionally stringent, a sort of name-and-shame policy to encourage energy-efficient retrofits. Whether New York’s buildings can be chastised into better behavior remains an open question. But the grades are really just a step on the way to stricter rules, with a mandate for building owners to cut their emissions by 40 percent by 2030; they’ll have to start taking steps toward that goal by 2024. Either way, as Department of Buildings Commissioner Melanie La Roca put it, the grades are a tool to give New Yorkers a clearer picture of where building owners stand when it comes to building a more environmentally friendly city.

While building owners in New York might be facing the most immediate regulatory consequences, the quest for greater sustainability in all types of buildings is happening everywhere. Buildings use up about 40 percent of all energy produced in the U.S., making them a prime opportunity for society to reduce its collective energy consumption and curb emissions.

Glass and glazing, of course, play an important role in creating a more efficient building envelope. And, as evidenced by the situation in New York, I expect there to be increasing opportunity in major window and glass improvement and retrofit projects in the years to come; all of those “D” rated buildings will have some catching up to do, after all. Another example: As USGlass recently recapped, the U.S. General Services Administration (GSA), which owns and leases thousands of historic properties across the country, will roll out the 2021 version of its standards in the coming months. With a sharp focus on building efficiency, some of these structures will need high-performance fenestration improvements to stay up to standard.

As energy requirements grow more stringent for all buildings, older and historic structures present an interesting challenge. Our industry has long been tasked with delivering increasingly high performance while simultaneously meeting the needs of modern architecture and design in new structures. The task in historic structures is the inverse: We must be able to deliver performance without disrupting the aesthetic integrity of an existing, culturally significant building.

As in everything we do, this requires some creativity and the right mix of high-performance products. For example, outright window replacement may not always be desirable when seeking to maintain historic integrity. But oftentimes, higher-performance glazing can be created using what’s already there—a single-pane window can be transformed/renovated into a double- or even triple-paned unit with the right technology, while low-E coatings can drive performance even further. Spacer selection is critical here—the right product will help maintain long-term performance. And in older (if not truly historic) structures, full window replacement utilizing high-performance framing and glazing technologies can be an effective way to maximize total building efficiency.

New York won’t be the only location seeking to retroactively improve the efficiency of its older buildings in the coming years. Our industry will be tasked with bringing the right solutions to these projects—and I’m confident in our ability to do just that.
