AECOsim Energy Simulator Pre-configured HVAC Systems
Calculation of Design Energy Cost/Energy Cost Budget and Calculation of the Proposed/Baseline Building Performance.
Energy Simulator provides pre-configured HVAC systems that can be used for the Calculation of Design Energy Cost/Energy Cost Budget and Calculation of the Proposed/Baseline Building Performance that comply with the ASHRAE 90.1 standard’s Section 11.3 and Appendix G.3.1 requirements. The following table lists all the available pre-configured HVAC systems, information regarding their heating and cooling performance parameters and the equivalent systems types listed in the standard’s modeling requirements for the budget building (Section 11.3.2) and proposed/baseline building (Appendix G3.1.1A and G3.1.1B).
