Energy Savings

FeelSTAT^TM enables significantly lower HVAC power consumption as it allows the User to correctly set cooling and heating limits at the “Edge of User Comfort” – see definition below.

HVAC Energy Savings were calculated for calendar year 2021 using the National Oceanic and Atmospheric Administration’s (NOAA) historical hourly meteorological data for selected U.S. and worldwide cities located in different climate zones. Carrying out hourly calculations over a full year using the generally acceptable HVAC concept of Degree-Days (as derived from NOAA’s hourly data) allows for good approximations of cooling and heating energy savings.

Comparisons were made between FeelSTAT^TM set at the “Edge of User Comfort” and a thermostat set at the temperature limits recommended by the governmental authorities.  The resulting energy savings were remarkable for some regions and are summarized in the Table below:

 

 

FeelSTAT^TM Substantial Carbon Footprint Reduction

A FeelSTAT^TM powered HVAC thermostat set at the “Edge of User Comfort” reduces carbon footprint proportionally to its proven reduction in HVAC energy consumption.

The example of the United States’ Los Angeles County, California is highlighted.  Per the U.S. Census, the population of Los Angeles County as of July 1, 2023 was 9,663,345 (number of housing units: 3,675,720). Our calculations show a total reduction for residential units of up to 408,000 TONS of CO₂ per year and an equivalent $40.8 million avoided yearly cost of carbon removal for a 10% market penetration rate of our technology, achievable through licensing and new OEM installations.  This impact is much higher when factoring in non-residential dwellings and with a higher market penetration rate. 

Our calculations compare the average HVAC energy reduction per Los Angeles County housing unit derived from using a FeelSTAT^TM powered HVAC thermostat set at the “Edge of User Comfort” versus a thermostat set at the U.S. Department of Energy’s recommended limits of 78°F (25.5°C) for cooling and 68°F (20.0°C) for heating. They assume the CO₂ emitted per generated kWh of cooling to be 0.39 kilograms and the CO₂ emitted per generated kWh of heating (natural gas) to be 0.44 kilograms. Last, they assume the direct air capture cost of CO2 to be $100/Ton.

Similar calculations for other regions of the world will yield proportional HVAC carbon footprint reductions to such regions’ percentage heating and cooling savings derived from using the FeelSTAT^TM technology.

FeelSTAT^TM Significant Energy Cost Savings and Short Payback Time

A FeelSTAT^TM powered HVAC thermostat set at the “Edge of User Comfort” provides its User significant energy cost savings and thus purchasing our technology has a very short payback time.

Again, the example of the United States’ Los Angeles County, California (July 1, 2023 pop. 9,663,345, with number of housing units of 3,675,720) is highlighted.  Our calculations show a countywide HVAC energy cost savings of up to $96 million per year for a 10% market penetration rate of our technology, achievable through licensing and new OEM installations. Much higher savings are obtained when factoring in non-residential dwellings and with a higher market penetration rate.  Payback time can be as short as 3.4 months.

Our calculations compare the average HVAC energy reduction per Los Angeles County housing unit derived from using a FeelSTAT^TM powered HVAC thermostat set at the “Edge of User Comfort” versus a thermostat set at the U.S. Department of Energy’s recommended limits of 78°F (25.5°C) for cooling and 68°F (20.0°C) for heating. They assume costs of $.25/kWh for cooling and $1.50/Therm for heating. Last, they assume the differential cost of FeelSTAT^TM powered HVAC thermostat vs. other thermostat to be $100.

Similar calculations to other regions of the world will yield proportional HVAC energy cost savings to such regions’ regions’ percentage heating and cooling savings derived from using the FeelSTAT^TM technology.

Edge of User Comfort

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is a worldwide recognized leading reference in all matters relating to HVAC.

FrontierTech International Inc. used ASHRAE’s definition of acceptable range of temperature and relative humidity and kept its FeelSTAT^TM cooling and heating limits within ASHRAE’s limits to provide a conservative estimate of energy savings.

For more information on ASHRAE’s definition of the limits of comfort, see ResearchGate, which summarized the “acceptable range of operative temperature and humidity ratio” using ASHRAE’s Standard 55:

Here ASHRAE defines the following extremes for cooling and heating limits: the far right line of the purple cooling zone and the far left line of the gray heating zone.  See Chart below:

 

 

Contrast ASHRAE’s limits with FeelSTAT^TM ’s “Edge of User Comfort” red line heating limit and blue line cooling limit (as plotted on the ASHRAE chart) used in FrontierTech International Inc.’s U.S. and worldwide cities’ energy savings calculations.  As stated above, FeelSTAT^TM ’s limits are conservative in comparison; this means that if ASHRAE’s own limits were to be strictly followed, then a FeelSTAT^TM powered thermostat would yield even more Energy Savings than what is shown in the Summary Table above.
