This analysis uses the Building Performance Rating Method to quantify performance and determine energy cost.
ANSI/AHRI Standard 1210-2011, Addendum 2015, (19) provides a test and drive system energy performance rating method for VFDs that operate ac induction motors in typical HVAC&R applications.
The current paths in the standard - the Energy Cost Budget method and the Performance Rating Method - can lead to different modelling protocols for different functions, according to Michael Rosenberg, a member of the Standard 90.1 committee.
To compute the percentage reduction in total annual energy and power costs, a performance rating method is used.
Taxpayers must use the performance rating method (PRM) to compute the percentage reduction in total annual energy and power costs.
In addition to the ECB method, Standard 90.1 includes a second simulation-based performance approach, Appendix G, the Performance Rating Method. While similar to ECB, Appendix G is more flexible but up to now, has not been allowed for demonstrating compliance.
The PCI for a rated building will always be calculated in the same way, using the performance rating method of Appendix G, but the [PCI.sub.t] will depend on the version of Standard 90.1 that is being complied with.
A lot of hype surrounds energy modeling performed for a whole building simulation, which looks at the utility consumption of a proposed building over an annual period, typically based on some sort of guideline such as the energy cost budget method, performance rating method, or the total building performance method.
Although this does not contain all of the changes reflected in the newest version of the performance rating method, it certainly gives the impression to determine the new requirements before starting a new model.
Standard 90.1-2010 has two whole building performance approaches: the Energy Cost Budget (ECB) method used for code compliance and the Performance Rating Method (PRM) used for LEED calculations and other beyond-code programs.
If we want to rate the energy efficiency of building designs that exceed the requirements of the standard, we use the performance rating method (PRM), found in Standard 90.1-2010's Normative Appendix G.
The Performance Rating Method prescribes a methodology for establishing a baseline building model.
