At Earth Networks, we’ve always believed an untapped opportunity exists to leverage our neighborhood level, densely populated weather network to take consumer energy savings to another level. A recent residential customer pilot by National Grid bears this out: Consumers who integrated WeatherBug Home’s HVAC control and optimization capabilities with their connected thermostat saved 16.5% electricity when cooling their home as compared to 5.1% HVAC savings from a connected thermostat –– saving 11.4% more in HVAC energy use.
The pilot by National Grid, a leading electricity and natural gas company that connects nearly 7 million customers to vital energy sources, finds that customers with a comprehensive service that integrates smart thermostats, smart meter data and our WeatherBug Home energy optimization and control capabilities experienced significantly improved Energy efficiency savings. How? Well a big part of our secret sauce is Earth Networks’ hyper-local network of weather stations, which are located at local schools, golf clubs and parks, deliver neighborhood level readings on temperature, wind speed and relative humidity, compared to other weather services that use readings at airports that can be a significant distance away from most homes. The location of weather observation sensors is important because 50% of a home’s energy usage is driven by the weather.
Specifically, the National Grid pilot found that:
- Homes in the pilot that integrated with WeatherBug Home saved significantly more electricity (16.5% energy savings during cooling season) compared to homes with only a smart thermostat and smart meter (5.1% savings).
- On a per-square-foot basis, the WeatherBug Home optimized group saved 0.1808 kWh/sqft, compared to 0.0358 kWh/sqft for the control group.
- Homes integrated with WeatherBug Home’s optimization and controls capabilities more effectively regulated temperatures than homes without these capabilities. Indoor air temperatures for the group with WeatherBug Home optimization controls more closely matched set points compared to the group without that optimization control.
In addition to the National Grid customer pilot results, Earth Networks studied data from its neighborhood located weather sensor network, against other providers with access to regionally located weather sensors. Earth Networks determined that its denser, neighborhood located sensor network resulted in:
- Higher accuracy predicting HVAC load and indoor temperatures
- 26% improved HVAC runtime prediction
- 8% temperature prediction improvement
We pride ourselves on delivering the most accurate weather and energy analytics to our consumer and enterprise customers. We are excited these studies demonstrate WeatherBug Home is providing more accurate energy usage predictions, and real value for consumers and utilities.
