Building Weather Station Logic Block

Description

Each building in Kaizen can have a nearby weather station associated with it. This setting is available on the building profile page.

Data from the selected weather station is accessible for use in logic rule through the Building Weather Station Data Logic Block.

Functionality

This block is ONLY available for Canadian and US buildings and the source of the data is respectively Environment Canada & Natural Resources, and National Oceanic & Atmospheric Administration (NOAA)The output of the Building Weather Station Data Logic Block is a data series such that:

• The sampling interval is 1 hour
• Values represent measurements/forecasts for a weather statistic selected in block settings.
• Data request: weather station ID has to be selected in the building profile.

The available weather statistics are:

• Outdoor Temperature
  • Units: [°C]
• Dew Point
  • – temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates
  • Units: [°C]
• Humidity
  • – current absolute humidity relative to the maximum possible humidity for that temperature, expressed as a percent.
  • Units: [%]
• Wind Speed
  • Units: [km/h]
• Heating Degree Hours
  • Calculated relative to a base temperature of 15 °C
  • Units: degree days [°C]
• Cooling Degree Hours
  • Calculated relative to a base temperature of 15 °C
  • Units: degree days [°C]

Logic Block Configuration

The two configuration parameters for the Building Weather Station Data block are:

• Name: sets the name of the block as it appears in the logic flow. It is best practice to use a concise, descriptive name.

• Weather type: defines the output weather statistic of the block. The options are:
  • Temperature
  • Dew Point
  • Humidity
  • Wind Speed
  • Heating Degree Hours
  • Cooling Degree Hours
