ASHRAE Standard 90.1 establishes the minimum energy efficiency requirements of buildings other than low-rise residential buildings for:
a) design, construction, and a plan for operation and maintenance; and
b) utilization of on-site, renewable energy resources
Two performance-based Compliance paths in Standard 90.1 include:
1) Energy Cost Budget Method, and
2) Performance Rating Method.
Both performance paths require that the simulation program shall be tested according to ASHRAE Standard 140, except for Sections 7 and 8 of Standard 140. The test results and modeler reports shall be posted on a publicly available website and shall include the test results of the simulation program along with the results of the other simulation programs included in ASHRAE Standard 140, Annexes B8 and B16.
Both performance paths have some identical requirements. For example, modeling 8760 hours per year, thermal mass effects and ten or more thermal zones. However, some requirements are different. This portal has check-listed these requirements for the software vendor for both ECBM and PRM.
ASHRAE Standards Overview
ASHRAE Standard 140 specifies test procedures for evaluating the technical capabilities and ranges of applicability of computer programs that calculate the thermal performance of buildings and their HVAC systems. Validation for Class I tests includes documentation of detailed diagnostic tests from Section 5, intended for simulation software capable of hourly or subhourly simulation time steps.ASHRAE Standard 90.1 establishes the minimum energy efficiency requirements of buildings other than low-rise residential buildings for:
