What is a baseline?
Baselines highlight changes in building energy use compared to past operations. They use actual building energy data, weather data, and schedule data to normalize and account for the current weather and schedule, allowing users to see at a glance when something has changed from how the building used to operate.
What is weather-normalization?
Weather normalization uses weather and energy usage data from past operations to create a model of how a building uses energy under specific weather conditions. The models can then use current weather data (outside air temperature, humidity, solar load, etc) as inputs and predict how much energy the building would use if nothing besides the weather had changed from the baseline period. This allows users to see how the building has operated under similar conditions in the past, and to more clearly see if anything has changed building energy usage besides the weather.
How to request baselines:
To add a new baseline, contact support@measurabl.com and provide the following information:
- Commodity to be baselined (e.g. Electricity, Natural Gas)
- Desired training period (e.g. January 1, 2024 to December 31, 2024) Note: An ideal training period is at least 12 months
- Baseline model name (e.g. “2024 Baseline” or “Reoccupancy Baseline”)
- Would you like this model to be the global default used for reporting, subscriptions, and measures?
Newly requested baselines will typically be available within 2 business days from the original request.
Non-electric baselines
Baselines can be created for any metered energy utility that has streaming interval data. This includes electricity, natural gas, steam, chilled water, and hot water. For seasonal utilities like natural gas and chilled water, it may be possible to create a baseline using less than 12 months, as typically Measurabl only needs shoulder season and either heating or cooling season data depending on the commodity.
Where does my weather data come from?
Weather data shown for the building (outside air temperatures and humidity) is sourced from a network of weather stations, and uses the geographically closest weather station that meets Measurabl’s accuracy standards. These weather stations are often located at airports, but may also be at other locations around a major city. This may mean there is a small variation from your building’s specific location and on site weather data.
