Animated temperature response curves and balance points

These temperature response curves are only available for Meter data.

Open, closed, and daily response lines

The solid lines show the average kW value that can be expected for this building at each temperature level at each time of day. The expected kW value is based on this building’s actual energy use data over the past 12 months, and the calculation prioritizes more recent data over older data.

The width of the line–along the x-axis–reflects the temperature range experienced by this building throughout the year (for example, it doesn’t get to 90 degrees at 4:00am in San Francisco).

Click on or off each of the open, closed, or daily curves in the chart’s legend to isolate one or more days on the graph.

Show or hide baselines and the balance point

Dotted baseline lines are an equal-weighted average off all of this building’s historical data, with no prioritization on data recency. The vertical line reflects this building’s balance point, which is the point where Snapmeter has estimated the building begins mechanical cooling.

Cooling is indicated when the line slopes up and to the right, while heating is indicated by a line that slopes down and to the right.

By comparing one of the solid lines to its dotted baseline, you can see how energy use has recently changed in this building compared to its long-term trend. If yours is a typical office building, where weekends are shutdown, you’d want to see the averaged Open days, or any given weekday individually selected, near the averaged Closed line at night and in the early morning.

As the building’s energy use picks up throughout the course of the day, you can compare it to the averaged Closed days in order to visualize the building’s typical operational load. This chart will also reflect the building’s typical start-up and shutdown times, in general or for each day of the week.
