ScoreCard Frequently Asked Questions
Choose a topic:
We provide a monthly digital energy audit (Energy ScoreCard) for homes. To evaluate how a property withstands the elements, our ScoreCards provide insight into a property’s energy efficiency with a customized energy audit, comparison to similar neighbors, and a bill forecast for the next month. We offer energy-saving tips based on your specific consumption, efficiencies, and habits. If you have a supported Wi-Fi thermostat, we will even rate the efficiency of your thermostat setpoint schedules and suggest temperatures to set to increase savings.
We use our real-time weather network to help determine and filter each of the three loads that make up your energy profile. During the summer, the base load is determined by looking at low and constant energy readings when heat should be leaving your property (mostly in the early mornings) throughout the month. The HVAC load is determined by examining times of high outdoor heat, where heat is entering your property and you likely have the air conditioner running.
Once these two main load signatures are determined, your property’s energy profile is reevaluated and updated, then correlated against our algorithms, which include a database of standard appliance loads and usage profiles. We then average your property’s monthly energy breakdown to show your average day’s energy profile.
You can download and/or email your ScoreCards when accessing them from a computer. Under each ScoreCard, you will find links allowing you to either download or email. To print, click on the thumbnail image of the ScoreCard you want to print, then press CTRL+P (on a PC) or Command+P (on a Mac).
Please note, on an iOS or Android device, you can only email your ScoreCards.
Our ScoreCards come in many different flavors depending on the availability of data. For instance, if we have access to smart meter data, users will get one version of a ScoreCard while another version will be received if we only have thermostat data from a thermostat manufacturer.
During months when minimal HVAC is being used (typically spring and fall), you will receive a Regional ScoreCard. This ScoreCard offers insights for an entire region, not for a specific property.
Users may also receive an Onboarding ScoreCard. This version precedes a personalized ScoreCard and identifies each section of the ScoreCard so users know what to expect the following month.
First, we build an energy model of the property using hyperlocal weather data and energy usage data from a smart meter or Wi-Fi thermostat. This model identifies the various energy flows through a property that requires the HVAC system to maintain a comfortable temperature.
For example, the Insulation score is determined by looking at the conduction energy and how your property responds on the hottest days. The Shading score is based on how much cooling is required to combat the solar energy and overall energy on the sunniest days. We do not actually look at your property or know how it was constructed — rather, the scores are based on estimates inferred from the data.
Scores will typically change because our models have now seen even more diverse weather conditions to better assess the efficiency of properties. Scores can also change because of behavior and/or seasonal changes. We prevent scores from being influenced by uncharacteristically high or low consumption days (such as days you have social gatherings or are away on vacations), but on rare occasions, these can still have an impact.
We first create an efficient schedule to match a user’s average thermostat schedule over the past month using regional and seasonal recommended setpoints. Then periods of energy waste (when the average schedule would drive higher energy consumption) and savings (when the average schedule would drive lower energy consumption) are calculated and compared to score the schedule.
