ASHRAE - 140 ADD A
Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs
|Publication Date:||30 April 2014|
The purpose of this addendum is to add a new set of cases, as new Section 5.5 of Standard 140, for testing the ability of whole-building energy simulation programs to model the air distribution side of typical heating, ventilating, and air-conditioning (HVAC) equipment. These cases test fundamental air-side system mass flow and heat balance modeling and are complementary to the current HVAC BESTEST and Furnace BESTEST cases of Sections 5.3 and 5.4, respectively, which test the ability to apply performance maps for modeling the working heat-transfer fluid side and combustion side of HVAC equipment. The new test cases are from Airside HVAC BESTEST: Adaptation of ASHRAE RP-865 Airside HVAC Equipment Modeling Test Cases for ASHRAE Standard 140, Volume 1: Cases AE101-AE445 A-5, by the National Renewable Energy Laboratory (NREL) in collaboration with the ASHRAE Standing Standard Project Committee 140 (SSPC 140) and other international software developers and simulation-trial participants. NREL's adaptation work builds off of ASHRAE Research Project 865 (RP-865)A-7, conducted at University of Nebraska Omaha, The Pennsylvania State University, and Texas A&M University.
