Provide a copy of the AEDG for office, retail, or warehouse, as applicable, to each team member as everyone, including the architect, mechanical and electrical engineers, lighting designer, and commissioning agents, are responsible for ensuring compliance. These are available to download free from the ASHRAE website. (See Resources.)

Besides energy modeling, you may need to use the exceptional calculation methodology (ECM) when any of the following situations occur: 

The energy software cannot carry out calculations for a specific systems like natural ventilation or unusual HVAC equipment.
Process loads are different in baseline and design cases and can influence total energy cost savings.
The proposed design can’t demonstrate savings with the modeling protocol and needs additional calculations. 

Projects generating renewable energy onsite should use Option 1 to best demonstrate EAp2 compliance and maximize points under EAc1. Other options are possible but won’t provide as much benefit. Like any other project, model the baseline case as a system c

Projects generating renewable energy onsite should use Option 1 to best demonstrate EAp2 compliance and maximize points under EAc1. Other options are possible but won’t provide as much benefit. Like any other project, model the baseline case as a system compliant with ASHRAE 90.1-2007, using grid-connected electricity, and the design case is an “as-designed” system also using grid-connected electricity.
