Rising energy prices and tightening operating margins continue to pressure multifamily owners and operators. While smart apartment technology has been gaining traction for years, one device consistently proves its value across portfolios: the smart thermostat. New data—from national surveys to real multifamily deployments—reveals that smart thermostats are delivering measurable, repeatable gains in energy efficiency, NOI, and resident satisfaction.
Below, we break down what the industry reports, what operators are experiencing in the field, and why the right thermostat design and connectivity model dramatically influence real-world results.
Residents Want Smart Thermostats
—And They Use Them
According to the NMHC & Grace Hill Renter Preferences Survey, 72% of renters say they are interested in smart thermostats—placing climate control among the most in-demand apartment features. This demand is tied directly to convenience, comfort, and energy control.
Smart thermostats are no longer seen as luxury upgrades; they’re emerging as an expected baseline amenity, especially in competitive Class A and workforce housing markets.
And when deployed correctly, resident adoption soars. Multifamily communities using the iApartments platform report an average 97% adoption rate, signaling that residents not only want thermostat control from their app—they actively engage with it.
Industry Data Confirms Strong Energy Savings
- A 2024 multifamily energy efficiency report revealed that owners who implemented smart thermostats and related smart-energy controls realized 18%–19% reductions in energy and water costs, far exceeding the 9%–12% savings they originally anticipated.
- Other case studies show operators saving 20%–30% annually on HVAC and boiler-related energy consumption across multi-community portfolios.
The Takeaway
Smart thermostats deliver consistent, portfolio-wide reductions in energy usage—primarily when supported by automation and remote control—$40,000/year in energy consumption. The technology was able to do this with automations that reduced HVAC runtime by 28%.

Why Connectivity Reliability
Determines Real Impact
Many smart thermostats rely on resident-managed Wi-Fi—an unreliable foundation
for any energy or automation strategy.
Poor connectivity leads to:
- Offline devices
- Missed schedules
- Failed automations
- Frustrated residents
- Lost savings
This is one reason multifamily operators often see inconsistent results across buildings or portfolios.
Cellular-connected thermostats solve the Wi-Fi problem
An emerging best practice is cellular-connected thermostats, which eliminate the Wi-Fi dependency.
Platforms like iApartments integrate the smart hub inside the thermostat itself, ensuring the device is
always online and responsive.
This reliability is one of the key drivers of higher adoption rates and more consistent savings.
As Sam Palmer, (former) EVP of Asset Management at Stoneweg US, put it:
“iApartments solved a lot of the problems we discovered with other platforms by integrating the hub within the thermostat.”
The Takeaway
When energy automations run 100% of the time, the savings compound quickly.
Real Multifamily Results: Smart Thermostats Drive NOI and Asset Value
Smart thermostat programs are producing meaningful financial impact for owners and operators:
- Workforce housing communities using automated HVAC controls saw 32%–55% reductions in vacant-unit HVAC runtime, translating into $17k–$33k annual savings per property.
- Resident-side automations reduced individual HVAC usage by 9%–27%, lowering monthly utility costs and improving satisfaction.
- Operators deploying enterprise automation gained hundreds to thousands of labor hours back, as remote temperature control eliminated the need for manual unit visits.
- Smart technology programs contributed to asset value increases of $1.6M–$2.3M per property, driven partly by NOI improvements, including thermostat-enabled energy savings.
-
The Takeaway
When combined with self-guided tours, centralized operations, and smart access, smart thermostats become a foundational lever for improving operational efficiency and NOI.
Conclusion: Smart Thermostats Are Now a Strategic Advantage
The data is clear: smart thermostats are no longer a nice-to-have amenity. They are a strategic, high-ROI investment capable of delivering:
- Lower energy spend
- Higher NOI
- Better sustainability performance
- Stronger resident satisfaction
- More efficient operations
-
And when paired with reliable connectivity and automated controls, these savings scale across entire portfolios—from Class A to workforce housing.
The Takeaway
Multifamily owners who adopt smart thermostats today aren’t just reducing their utility bills. They’re building the operational and financial foundation modern portfolios require.
