FYI, The DoD has just mandated that they will follow ASHRAE 90.1 2013 for sustainability and mandatory requirements. This locks in the receptacle controls in under federal law (EPACT 2005) for DoD facilities. I formally submitted to ASHRAE in 2012 using the 24/7 reasoning for exempting the offices being controlled if we only had required receptacles. At the time we only put in enough receptacles or connections to power the computers and printers which by federal mandate have to be powered ON and connected to the network whenever possible. We cannot switch them off with the sensors as ASHRAE intended. I was straight out rejected. I went to headquarters and requested them to remove the paragraph in the criteria and was told it was inexpensive and a good idea to follow along. Before this last mandate, I could exempt the controlled receptacles in break rooms and conference rooms from the Criteria. Now it is not an option. I now add double the needed receptacles and route the extra receptacles through a relay that has a coil controlled by the room sensor (No need to worry if 120V or 277V). We now can only feed 6 workstations from one system furniture power line (limits of the channel space in all manufacturers). It is known these switched receptacles are not getting used. Just when you though it could not get worse on this topic. This is being done on projects where most engineers are trying to get our military usable spaces with skeleton budgets. Personally I see this as a cowards way to justify sustainable design.

just for conversation sake, what state(s) are you running into this in?
i'm assuming it's nationwide.
something that is done here to comply with title 24:2013 is to split
every outlet, switching the top half, and leaving the bottom half hot.
this way, you are pulling 3 wire MC, and it's pretty straightforward.
most folks here are putting this stuff togeather using something like nLight.

This is for Federal facilities. No state driven reference to ASHRAE 90.1.
For California Title 24 switching half the outlet was originally by local manual switch to reduce non-essential loads on Brown out days. Are they now using occupancy sensors for plug load instead?
ASHRAE 90.1 identified computers as the original reason for the requirement. They want them switched off when no one is using them as a energy savings. I looked into the 24/7 exemption and was denied.
What owner wants to be told that their computer, cell phone charger, telephone, vending machine, coffee maker, smart TV, or similar will be forced to turn off. We cannot allow this by federal mandate. Computers and VOIP telephones are updated in the off hours nightly.
There are already ways society and manufacturing reduces the energy usage for these things.
In short the switched receptacles are not getting used. We are spending the peoples money on manufacturing energy, material, and labor for something that does not get used or save energy.
Is that what you want to spend millions on?

I doubt many jurisdictions around here would adopt this.

nope. we have a wall to build.
i hadn't thought about that. will the portion of the wall in
california have to have controlled outlets, and occupancy sensors?
it'll need a title 24 certification.....
