The project seeks to apply the following Exception to ASHRAE 90.1-2019 G1.2.2 to its energy model developed under ASHRAE 90.1 Appendix G (2007, 2010, 2013, or 2016):
“Exception to G1.2.2
Energy used to recharge or refuel vehicles that are used for off-building site transportation purposes shall not be modeled in the baseline building performance or the proposed building performance.”
Yes, it is acceptable for the project to exclude the electric energy consumption associated with electric charging of vehicles used for off-site transportation such as buses, commuter vehicles, or privately owned cars, provided that the project provides separate electric metering for the electric vehicle charging versus all other electric energy used within the LEED project boundary. When reporting post-occupancy building energy usage in accordance with EA Prerequisite: Building Metering, the project must separately report both building energy usage and energy associated with the electric vehicle charging, as applicable.
This exception applies only to the energy consumption for EV Chargers used by commuters and transit vehicles. The exception does not apply to energy consumption for EV Chargers used for vehicles on-site (e.g. golf carts on a golf course; electric fork lifts; etc.); energy consumption for EV Chargers used for vehicles on-site must be included in the building energy model.
