When I started working, mechanical engineers practically needed a slide deck to explain what “net‑zero” meant. These days, most clients arrive with a basic understanding — or at least the expectation that new buildings will aim for it.

The more interesting development is how early in the design process these conversations happen. Ten years ago, energy modeling was introduced halfway through design development. Now it’s often a topic in the first meeting, sometimes even before we’ve seen the site.

One of our recent mid‑rise housing projects didn’t set out to be net‑zero. It simply became the default because the design decisions — envelope continuity, solar exposure, mechanical zoning — pushed us there without anyone grandstanding about it. That says a lot about where the industry is heading.

“Biophilic design” used to show up in presentations like a soft, conceptual idea. A sketch of a courtyard, a wall of vines. In practice, it often turned into a lonely planter in the lobby.

Now the conversation is more grounded. Instead of talking about “nature,” we’re talking about daylight factors, ventilation pathways, and maintenance plans. Plants are no longer symbolic; they’re integrated into the mechanical strategy.

On an office retrofit we completed last year, a client insisted on real greenery throughout. We pushed back a bit (every architect who has watched an office fiddle-leaf fig turn brown knows why). But once the mechanical engineer joined the conversation, we ended up designing the planting as part of the air filtration system. It worked — and more importantly, it’s still alive.

Modular building used to feel like rolling the dice. Some projects went smoothly; others arrived on trucks slightly out of square.

Lately, the manufacturers have matured. Quality control is no longer the big worry — coordination is.

We’ve had to adjust how we document things. There’s less room for improvisation on site, which veteran contractors sometimes struggle with. But for complex urban infill projects, modular has been a gift. Shorter build times mean fewer complaints from neighbors, and less exposure to weather has noticeably improved envelope performance.

I wouldn’t say modular fits every building type, but it has finally moved beyond its reputation for being cheap or temporary.

A decade ago, green roofs were described as “amenities.” Now they show up in stormwater reports before they appear in concept diagrams.

Cities are quietly leaning on them to manage runoff, especially in older districts where the pipes under the street haven’t been updated since the 1950s. I’ve sat in meetings where city engineers have flat-out said they approve green roofs primarily to avoid replacing aging sewer lines — hardly romantic, but very real.

For architects, this shift means green roofs are no longer optional “nice to have” features. They’re functional systems with structural, drainage, and maintenance requirements we have to integrate from day one.

People often assume sustainability is the main reason adaptive reuse is taking off. In practice, the motivations are mixed.

Lead times for steel and some mechanical equipment have been wildly unpredictable for several years. Renovating existing buildings avoids some of those bottlenecks. We’ve had projects where keeping the original concrete frame saved nearly six months of schedule — and the embodied carbon savings were simply a bonus.

There’s also a growing recognition that older buildings have spatial proportions that are almost impossible to recreate affordably today. Ceiling heights, window openings, structural rhythms — these “imperfections” often become the character that anchors a project.

Mass timber is having a moment, but it’s a mature moment. Engineers trust it. Contractors have experience with it. Fire marshals still ask their questions, but there’s less anxiety all around.

On a recent civic project, we used timber for the upper levels. The trades appreciated the ease of installation, the acoustics team appreciated the damping properties, and the client liked that people simply enjoy being in timber buildings. That last point isn’t measured in performance metrics, but it’s real — you can feel it when you walk through during punchlist.

Timber isn’t a universal solution, but it has earned its place in the palette.

For years, “smart building” technology felt like a collection of gadgets: thermostats with apps, lights with sensors, dashboards nobody looked at.

The difference now is integration. Instead of scattered devices, we’re seeing building systems that actually communicate with each other.

One of our university clients recently installed a system that shifts cooling loads based on predicted occupancy — not scheduled, predicted. It sounds futuristic, but in use, it’s surprisingly simple. The building just feels more even, more comfortable, without the typical swing between hot and cold zones.

The big change is that owners are finally willing to invest in commissioning, which is where smart buildings either succeed or fall apart.

After years of relying heavily on mechanical systems to solve all comfort issues, there’s a renewed appreciation for basic building physics.

Orientation, shading, massing, ventilation — these aren’t glamorous topics, but they’re foundational. We’ve worked on a few projects lately where the passive moves did more for performance than the active ones.

A courtyard repositioned by 12 degrees solved an overheating issue. A simple perforated metal screen reduced solar gain on a western façade dramatically. None of these were expensive changes; they just required earlier thinking.

This one’s harder to quantify, but it’s palpable. Developers who used to talk about “iconic architecture” are now asking about comfort, long-term flexibility, and operating costs.

Mixed-use neighborhoods, transit access, walkability — these topics have moved from the periphery of planning meetings to the center. Part of it is generational, part of it economic, and part of it environmental. But the result is that buildings are being designed with a less heroic, more civic mindset.

It’s a healthier direction.

Not every client is ready to talk about regenerative design, but the ones who are tend to be highly motivated. They’re asking how the building can improve the site, not just minimize impact.

Sometimes that means restoring a wetland edge. Sometimes it means reconnecting a habitat. Sometimes it’s as simple as designing a courtyard that channels rainwater into a landscape instead of a pipe.

These ideas aren’t radical anymore. They’re simply the next step.

After 25 years in practice, I’m more optimistic about the future of architecture than I’ve been in a long time. Not because the challenges are easy — they aren’t — but because the conversations happening in studios, engineering offices, planning departments, and construction trailers feel more aligned than I’ve ever seen.

Sustainable architecture in 2026 isn’t defined by sweeping gestures. It’s defined by a thousand practical decisions that add up to a different way of building.
