Weather data is a necessary input for utility analysis, because weather has a strong impact on heating and cooling energy in most buildings.

ManagingEnergy stores the daily mean temperatures for a long list of weather stations, updated weekly.  When a new facility is added, the system uses  the address information to geocode the site by figuring out the latitude and longitude.  From there it automatically finds the closest weather station.


                                                               ManagingEnergy must know the closest weather station to create a baseline model for any meter.   Fill in the Facility address under Edit Facility, click Validate, and let ManagingEnergy find the weather station.

Weather Data can be reviewed but not edited.

Typical Meteorological Year (TMY) Weather Data

For each weather station, ManagingEnergy maintains a second set of weather data representing the weather expected in a typical or average year. This weather data is calculated by averaging weather data over the previous 10 years. The difference between the actual weather data and TMY weather data is subtle but important. Actual weather data helps answer questions about weather related effects over an actual span of time where you have corresponding meter readings and bills. TMY data answers questions about weather effects in a hypothetical typical year. The typical meteorological year is the most reliable for budgeting and calculating savings from conservation opportunities.


                                    Impact of Global Warming on TMY's.  We are sometimes asked if the TMY data is obsolete due to global warming. Since the typical meteorological data is based on the average of the last 10 years of actual weather data, any impacts of global warming will be integrated into the dataset over time.

Available in Module 3 - Conservation and Renewal

Select a facility under the Advanced Analysis tab, then use the Weather Data button to review the temperature profile for the closest weather station.   TMY (Typical Meteorological Year) data for the closest TMY station is also available under this feature.  Users can review weather patterns but cannot make changes.
