A smart thermostat quickly learns to optimize building microclimates for both energy consumption and user preference.
Buildings account for about 40 percent of U.S. energy consumption, and are responsible for one-third of global carbon dioxide emissions.
Making buildings more energy-efficient is not only a cost-saving measure, but a crucial climate change mitigation strategy.
Hence the rise of “smart” buildings, which are increasingly becoming the norm around the world.
Smart buildings automate systems like heating, ventilation, and air conditioning (HVAC); lighting; electricity; and security.
Automation requires sensory data, such as indoor and outdoor temperature and humidity, carbon dioxide concentration, and occupancy status.
Smart buildings leverage data in a combination of technologies that can make them more energy-efficient.
Since HVAC systems account for nearly half of a building’s energy use, smart buildings use smart thermostats, which automate HVAC controls and can learn the temperature preferences of a building’s occupants.
In a paper published in the journal Applied Energy, researchers from the MIT Laboratory for Information and Decision Systems (LIDS), in collaboration with Skoltech scientists, have designed a new smart thermostat which uses data-efficient algorithms that can learn optimal temperature thresholds within a week.
“Despite recent advances in internet-of-things technology and data analytics, implementation of smart buildings is impeded by the time-consuming process of data acquisition in buildings,” says co-author Munther Dahleh, professor of electrical engineering and computer science and director of the Institute for Data, Systems, and Society (IDSS). Smart thermostat algorithms use building data to learn how to operate optimally, but the data can take months to collect.
To speed up the learning process, the researchers used a method called manifold learning, where complex and “high-dimensional” functions are represented by simpler and lower-dimensional functions called “manifolds.”

I’ve wondered for some time when high-end coolers will be made with aerogel. Seems obvious, so someone has undoubtedly considered it.
Not to mention when the landlord knocks out a few walls to please a tenant. Or the building wasn't commissioned properly.
Then try to throw daylighting into the mix...
If only these smart thermostats could be connected to the vote tabulators, I would never have to leave the house.
Yea, and all that aerogel will cost you a fortune.
I think it has more to do with consolidating everything in a few mega corporations. When the time comes, it will be much easier to seize a few hundred big companies that it will be 100’s of thousands of small ones. It will also help to have the hardest working and most motivated people demoralized.
No price is too high if you need to save the planet. /s
Fragile gadgetry aside, a smartly built building is smarter. For a start, build the houses to be more square, and eliminate hallways. Stop worrying about the vanity of false-front aesthetics. Give us more specific code elements for hip roofs for energy efficiency and wind loads. There’s no good reason for the Wood Frame Construction Manual. It’s a racket. And remove obstructions from codes for mass heaters (masonry heaters, rocket stove mass heaters, etc.).
A wife/girlfriend is your thermostat.
LOL. I was just thinking along the same lines. This morning is a two-burner on the kitchen stove.
A smart thermostat makes it easier for the government to control your energy use when the Biden Administration enacts all their carbon taxes.
Agreed. I have worked at a desk in a new build-out. It got so bad I brought a thermometer in to work - it read 94 (F) on my desk. When I finally threatened to come in wearing Hawaiian shirts and shorts they re-balanced the system. I think it was the shorts threat... I’ve also worked in labs where “for the good of the equipment” they were kept at 65 degrees. We were all wearing hoodies and gloves because 65 doesn’t sound too bad, until you sit still working on a computer at 65...
There’s nothing Smart at my house. Not even me :)
My dog? Well...
The reason for the high price is twofold. First, it has not yet entered the realm of mass production, enigmatic because of the second reason that the demand for it is sky high.
Theoretically, even if it was being produced in vast quantities, the entire production for years is already ‘sold’, back ordered by government and industry. Commercial public use is far down the priority list.
The ‘smart’ thermostat will be controlled by the government through the local electric company, even if you use natgas)...
I went back to the old, set the temperature and leave it, last year. Even the timer ones were a pain.
The dystopian smart home/building will have all kinds of ramifications!
The toilet is not full and does not need flushed yet, Dave.
Cold water will work fine for washing the dishes, Dave.
“Zoning costs money”
That’s why my houses with forced air heating have had one zone. We’ve been happy with it.
I’m still using the Honeywell Chronotherm II “setback” thermostat I installed in 1988, too. It’s got features I don’t see on today’s thermostats, like a simple “Hold” button, a simple “Run Program” button (to go back to auto), and a “Prev Period” button to switch back to the previous program setting.
Now imagine putting such a system in your home.
Governor Neusom thinks you’ve used enough power for the day?
Government turns off your A/C on a baking hot day.
Governor Coumo thinks you used enough power for the day?
Government turns off your heat on a frosty winter’s day.
Turn down when you leave your home or go to bed. Turn up when you return to your home or get out of bed. There I solved the adjusting the thermostat during heating season algorithm.
A 10mm thick 1sqf. Blanket is $30. And I think image the carbon footprint of production would make the greenies cringe in rage.
