Hi, My name is Olga and I am using Haystack tags for tagging values from a building model. I am new to Haystack and am not a building engineer. I need some help in tagging one of my data points.

I have a chilled water system - a secondary system with 2 pumps. One of the data points being collected on this system is defined as a heat exchange rate (BTU/hour) which I have been told is a calculated value based on data collected from other sensors. I am stuck in which tags to apply.

This is what I have so far:

id: @building1.chw.heatExchangeRate

dis: "calculated heat exchange rate for the chilled water system"

point

siteRef: @B1

equipRef: @B1.chilledWaterSystem

???

sensor (not sure if I should use sensor or cmd here)

curVal

kind: "Number"

unit: "btus_per_hour"

tz: "Los_Angeles"

Any help would be greatly appreciated.

Depending on the context, I think previous discussions have been around treating that as a type of "thermal meter" using the power tag - see /doc/Energy#thermalMeters
