here some notes on requirements for properties ontology.
The following requirement is derived from a comment by Richard Pinka (CTU Prag):
Varying Properties
Problem: The COP or other performance measures of a piece HVAC equipment are dependend on the operating conditions. For example the efficiency of a chiller changes dependend on how close or how far away it is from its optimal performance point. Hence, in product data of a chiller there might not be one single value for the COP but a mathematical function or tabular data defining dependent on a input the calculation of the COP.
Requirements: A property ontology must be able to describe tabular data or mathematical function to express properties which have a range of values.
