What is a smart thermostat? What is a Wifi thermostat?Characteristics
Programmable thermostats
Retains basic thermostat capability, regardless of link status
Can collect temperatures, HVAC run-times and HVAC performance information from field systems
Temperature stabilityProgrammable for schedules and setbacks
Wi-Fi thermostats
Wi-Fi-enabledOnline dashboard and/or mobile app connected to the user account
Intuitive user interface (UI) that may include touchscreen or buttons
Smart thermostats
Proximity sensing allows a user to accept and act upon external data (like the location of a smart phone).
Occupancy sensing directly detects and acts upon internal sensors (inside the thermostat).
“Learning,” optimization, or adaptive control; algorithms that learn user behavior or track usage to improve performance
Basic demand response capabilities: allows remote connection with utilities, who, with authorization, can adjust thermostat settings during peak demand periods (optional).

Key Characteristics of Smart Thermostats
Before ENERGY STAR, we had establish our own parameters… these are “prescriptive”: Connected online / via Wi-Fi Automated control of HVAC dependent on
schedule, occupancy, or proximity “Learns” and mimics occupants’ behavior and
patterns Algorithms to improve & optimize HVAC system
performance Can include basic demand response / peak load
control capabilities
Customer Cost Range:
$125 - $245
Incentive Range: $25 - $100 per unit

Smart Thermostat Market & Leaders
Device shipments expected to go from 1.3 million in 2015 to 29.1 million in 2025
10% of Americans have installed a smart thermostat (source: Shelton Group EnergyPulse Special Report)
(Q3 2016)

Smart & WiFi Thermostats – Other Offerings
Some companies offer HVAC optimization via a software platform that can control WiFi-connected thermostats in large volumes Examples: EnergyHub, Whisker Labs, Tendril
One company – EcoFactor – does not manufacture its own thermostat, but got its software platform certified by ENERGY STAR

Bonus Round! Smart controls for DHPs Same or similar capabilities as smart thermostats, such as: Connectivity via WiFi Ability to program and set schedules remotely Proximity sensors, combined with smart phones, can detect occupancy and turn
DHPs on or off Some also provide DR capabilities
Primary differentiating characteristic: these have one (or more) wall-mounted units that send infrared signals directly to indoor heads of DHPs (just like a remote control)

Precedent #1: ComEd’s “One Million Smart Thermostats” Initiative
In 2015, ComEd (along with Nicor Gas, Peoples Gas, and North Shore Gas) announced an initiative to install 1 million smart thermostats in the Chicago area by 2020
Requirements: 2017: Rebate amount of up to $150 2018: Reduced the rebate to a flat $100 Also now required to be an ENERGY STAR Certified Smart Thermostat
By the end of 2017, they had 119,000 smart t-stats installed Average savings of 300 kWh per home annually Goal for 2018: 83,000

Precedent #2: Entergy Arkansas
Energy efficiency program, in partnership with the DR program, is collecting 5-minute interval data
5 minute interval data = 5,500 data points per day 2,000,000 per year
Program is nearing 2000 installed thermostats, which is at least 200 million lines of data annually
Using this to identify HVAC system outliers, such as those that need tune-ups

Potential for Energy savings and DR
Future Landscape for Smart Thermostats
© 2017 CLEAResult. All rights reserved. 23
What does the future landscape look like for the smart thermostat product category?
Smart home products – including thermostats – will get fancier! Like the soon-to-be-released Microsoft GLAS
It will also become more difficult to tell which products actually save energy, as manufacturers add more bells and whistles (some of which may contribute to energy increases)

New Program Opportunities
HVAC System Optimization Potential to use automation capabilities of smart thermostats to enable deeper
savings at the home level without manual intervention Savings potential exists, but how much is unknown
Remote QA / QC Data provided by smart thermostats could give us the ability to determine quality
of installation / equipment without “rolling trucks” EE + Demand Response = IDSM Many programs already use smart thermostats for DR exclusively What is the potential for EE + DR?
