Dear All, Would it be possible to claim EAc1 credits for local automation in dwelling units to achieve the following: (1) Automatic shut down of lighting and HVAC units when there is no occupancy. (2) Taking advantage of lower electricity tariffs due to smart metering to run appliances at night time?

1. Lighting gets a 10% credit on the room lighting power density (see 90.1 Table G3.2). HVAC occupancy controls would probably require a schedule change so you can get credit but have to follow the exceptional calculation method. 2. Taking advantage of off-peak rates gets tricky since the utility rates in both are supposed to be identical. Just applying an off-peak rate to both models will help capture most but not all of the savings. In order to use a different rate again follow the exceptional calculation method.
