Artificial Intelligence Steps In to Lower Carbon Footprint of Buildings

Property companies are increasingly offering AI energy software to help cut the greenhouse-gas emissions of buildings

Artificial intelligence is starting to help buildings go greener.

Keeping our buildings running contributed roughly 26% of global energy-related greenhouse-gas emissions in 2022, according to the International Energy Agency. For the world to reach net-zero emissions by 2050, the agency says the energy that these buildings consume per square meter (around 11 square feet) needs to decline by around 35% by 2030.

Developers and construction companies have pursued more-efficient energy use in buildings over the past couple of decades. Leadership in Energy and Environmental Design, or LEED, certifications are given to buildings that meet standards that conserve energy, water, waste and other environmental goals.

Governments are also introducing increasingly stringent energy codes for commercial spaces. Still, more than 80% of buildings don’t have smart systems to efficiently manage their energy use.

JLL, which manages billions of square feet of commercial real estate around the world, has been making a string of investments to bring AI systems to companies looking to cut their emissions. The business case: Eco-friendly buildings charge higher rents and are on the market for less time. JLL says it expects 56% of organisations to pay a premium for sustainable spaces by 2025.

“We want to make every building out there as smart as it can be,” said Ramya Ravichandar, JLL Technologies’s vice president, technology platforms—smart and sustainable buildings. “If you can’t measure what matters, you can’t make the change.”

JLL’s investments include in Turntide, a company based in Sunnyvale, Calif. that installs electric motors coupled with small computers which learn from patterns to more precisely control heating and cooling, and Envio Systems, a Berlin-based company that develops sensors to track a building’s use, occupancy and other factors to adjust lighting, cooling and similar energy-related activities.

“Do I need to keep the lights on? Do I need to turn off the air conditioning on floor three because the entire company is working from home this week?,” Ravichandar said. “If you have a system, it is relentless and constantly processing this information.”

Generally, AI building systems learn from historical patterns and the daily habits of occupants to predict and power things on and off. For instance, software and hardware that automatically manages lights, heating and cooling can help buildings cut 20% or more of their yearly energy use.

Nevertheless, hurdles remain to installing more AI systems, including gathering data from a wide range of sources in buildings, such as sensors, which often aren’t interconnected enough. “Retrofitting existing buildings with such sensors and infrastructure, as well as ensuring consistent data quality, can be resource intensive,” Ravichandar said.

Not enough data

AI has big potential to cut the emissions of buildings, but it is only as good as the data it learns from. Only 10% to 15% of buildings have the equipment or systems in place to gather the data needed to support AI, said Thomas Kiessling, chief technology officer of Siemens Smart Infrastructure. “AI in buildings works if you have the data,” he said. “Bad data means you can’t do any kind of schedules, rules or more sophisticated use cases around artificial intelligence. You have to have the data.”

Siemens uses AI to compare one building to a thousand similar buildings to predict what the energy savings could be after an upgrade to a smart-energy management system.

“Even if you just know the address of that commercial building, and maybe you have the energy bill, and maybe you have some high level information of what kind of HVAC brand the building uses, that is these days enough to compile a profile of the building with respect to what is likely you could reap,” Kiessling said.

Otherwise, lower-cost sensors, such as for lighting and cooling, can help save energy for companies that don’t have a sophisticated management system.

Venture-capital firm Fifth Wall’s $500 million fund is focused on decarbonising buildings and invests roughly a third of its money in startups with some kind of AI offering, both in software and hardware, the fund’s co-manager Greg Smithies said. A bigger focus is using more sustainable materials, such as concrete and steel made with renewable energy.

Smithies says AI can help with quickly and cheaply identifying where it makes economic sense to upgrade buildings, fill out permits that vary between countries, draw up mock-ups of designs and come up with chemistry for sustainable materials.

“The main message overall is we’re not going to save the planet with software, and AI is software,” Smithies said. “But AI is an interesting piece of the puzzle.”

Everyone Wants a Room Where They Can Escape Their Screens

Weary of ‘smart’ everything, Americans are craving stylish ‘analog rooms’ free of digital distractions—and designers are making them a growing trend.

James and Ellen Patterson are hardly Luddites. But the couple, who both work in tech, made an unexpectedly old-timey decision during the renovation of their 1928 Washington, D.C., home last year.

The Pattersons had planned to use a spacious unfinished basement room to store James’s music equipment, but noticed that their children, all under age 21, kept disappearing down there to entertain themselves for hours without the aid of tablets or TVs.

Inspired, the duo brought a new directive to their design team.

The subterranean space would become an “analog room”: a studiously screen-free zone where the family could play board games together, practice instruments, listen to records or just lounge about lazily, undistracted by devices.

For decades, we’ve celebrated the rise of the “smart home”—knobless, switchless, effortless and entirely orchestrated via apps.

But evidence suggests that screen-free “dumb” spaces might be poised for a comeback.

Many smart-home features are losing their luster as they raise concerns about surveillance and, frankly, just don’t function.

New York designer Christine Gachot said she’d never have to work again “if I had a dollar for every time I had a client tell me ‘my smart music system keeps dropping off’ or ‘I can’t log in.’ ”

Google searches for “how to reduce screen time” reached an all-time high in 2025. In the past four years on TikTok, videos tagged #AnalogLife—cataloging users’ embrace of old technology, physical media and low-tech lifestyles—received over 76 million views.

And last month, Architectural Digest reported on nostalgia for old-school tech : “landline in hand, cord twirled around finger.”

Catherine Price, author of “ How to Break Up With Your Phone,” calls the trend heartening.

“People are waking up to the idea that screens are getting in the way of real life interactions and taking steps through design choices to create an alternative, places where people can be fully present,” said Price, whose new book “ The Amazing Generation ,” co-written with Jonathan Haidt, counsels tweens and kids on fun ways to escape screens.

From both a user and design perspective, the Pattersons consider their analog room a success.

Freed from the need to accommodate an oversize television or stuff walls with miles of wiring, their design team—BarnesVanze Architects and designer Colman Riddell—could get more creative, dividing the space into discrete music and game zones.

Ellen’s octogenarian parents, who live nearby, often swing by for a round or two of the Stock Market Game, an eBay-sourced relic from Ellen’s childhood that requires calculations with pen and paper.

In the music area, James’s collection of retro Fender and Gibson guitars adorn walls slicked with Farrow & Ball’s Card Room Green , while the ceiling is papered with a pattern that mimics the organic texture of vintage Fender tweed.

A trio of collectible amps cluster behind a standing mic—forming a de facto stage where family and friends perform on karaoke nights. Built-in cabinets display a Rega turntable and the couple’s vinyl record collection.

“Playing a game with family or doing your own little impromptu karaoke is just so much more joyful than getting on your phone and scrolling for 45 minutes,” said James.

Screen-Free ‘Escapes’

“Dumb” design will likely continue to gather steam, said Hans Lorei, a designer in Nashville, Tenn., as people increasingly treat their homes “less as spaces to optimise and more as spaces to retreat.”

Case in point: The top-floor nook that designer Jeanne Hayes of Camden Grace Interiors carved out in her Connecticut home as an “offline-office” space.

Her desk? A periwinkle beanbag chair paired with an ottoman by Jaxx. “I hunker down here when I need to escape distractions from the outside world,” she explained.

“Sometimes I’m scheming designs for a project while listening to vinyl, other times I’m reading the newspaper in solitude. When I’m in here without screens, I feel more peaceful and more productive at the same time—two things that rarely go hand in hand.”

A subtle archway marks the transition into designer Zoë Feldman’s Washington, D.C., rosy sunroom—a serene space she conceived as a respite from the digital demands of everyday life.

Used for reading and quiet conversation, it “reinforces how restorative it can be to be physically present in a room without constant input,” the designer said.

Laura Lubin, owner of Nashville-based Ellerslie Interiors, transformed a tiny guest bedroom in her family’s cottage into her own “wellness room,” where she retreats for sound baths, massages and reflection.

“Without screens, the room immediately shifts your nervous system. You’re not multitasking or consuming, you’re just present,” said Lubin.

As a designer, she’s fielding requests from clients for similar spaces that support mental health and rest, she said.

“People are overstimulated and overscheduled,” she explained. “Homes are no longer just places to live—they’re expected to actively support well-being.”

Designer Molly Torres Portnof of New York’s DATE Interiors adopted the same brief when she designed a music room for her husband, owner of the labels Greenway Records and Levitation, in their Lido Beach, N.Y. home. He goes there nightly to listen to records or play his guitar.

The game closet from the townhouse in “The Royal Tenenbaums”? That idea is back too, says Gachot. Last year she designed an epic game room backed by a rock climbing wall for a young family in Montana.

When you’re watching a show or on your phone, “it’s a solo experience for the most part,” the designer said. “The family really wanted to encourage everybody to do things together.”

Analog Accessories

Don’t have the space—or the budget—to kit out an entire retro rec room?

“There are a lot of small tweaks you can make even if you don’t have the time, energy or budget to design a fully analog room from scratch,” said Price.

Gachot says “the small things in people’s lives are cues of what the bigger trends are.”

More of her clients, she’s noticed, have been requesting retrograde staples, such as analog clocks and magazine racks.

For her Los Angeles living room, chef Sara Kramer sourced a vintage piano from Craigslist to be the room’s centerpiece, rather than sacrifice its design to the dominant black box of a smart TV. Alabama designer Lauren Conner recently worked with a client who bought a home with a rotary phone.

Rather than rip it out, she decided to keep it up and running, adding a silver receiver cover embellished with her grandmother’s initials.

Some throwback accessories aren’t so subtle. Melia Marden was browsing listings from the Public Sale Auction House in Hudson, N.Y. when she spotted a phone booth from Bell Systems circa the late 1950s and successfully bid on it for a few hundred dollars.

“It was a pandemic impulse buy,” said Marden.

In 2023, she and her husband, Frank Sisti Jr., began working with designer Elliot Meier and contractor ReidBuild to integrate the booth into what had been a hallway linen closet in their Brooklyn townhouse.

Canadian supplier Old Phone Works refurbished the phone and sold them the pulse-to-tone converter that translates the rotary dial to a modern phone line.

The couple had collected a vintage whimsical animal-adorned wallpaper (featured in a different colourway in “Pee-wee’s Playhouse”) and had just enough to cover the phone booth’s interior.

Their children, ages 9 and 11, don’t have their own phones, so use the booth to communicate with family. It’s also become a favorite spot for hiding away with a stack of Archie comic books.

The booth has brought back memories of meandering calls from Marden’s own youth—along with some of that era’s simple joy. As Meier puts it: “It’s got this magical wardrobe kind of feeling.”
