ASHRAE Standard 205P (Standard Representation of Performance Simulation Data for HVAC&R and Other Facility Equipment) defines data exchange formats that allow detailed equipment performance characteristics to be published by manufacturers and then read by analysis software without human interaction. This will result in standard methods for automated manipulation of performance data in BIM and other tools, increasing both productivity and accuracy. The presentation provides an overview of Standard 205P and include data examples for unitary air conditioners, liquid chillers, and fan assemblies.

This presentation looks at continuous change in chiller performance ratings over the past 30 years. A brief overview of the rating calculation methodology is given and the speaker discusses the changing methods used, expectations and requirements, and formats which have been provided. The development of a standard file type is merely another step in this evolution.

This presentation discusses how the adoption of a standard for equipment data will change the development and use of building simulation programs. From the current situation where the developer must create equipment libraries and detailed instructions for creating new data files for the users, to a next-generation where the software can automatically load new equipment data without the user having to perform any formatting, to a future approach where the data is transmitted between manufacturer and software without any user input.

This presentation explores the impact of Standard 205 on the consulting energy modeling process including a sample case study. This explores how the accurate representation of chiller performance can result in better comparative results and improved consulting ability.
