Is that what you want to spend millions on?
We are spending the peoples money on manufacturing energy, material, and labor for something that does not get used or save energy. In short the switched receptacles are not getting used. There are already ways society and manufacturing reduces the energy usage for these things. Computers and VOIP telephones are updated in the off hours nightly. 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. I looked into the 24/7 exemption and was denied. They want them switched off when no one is using them as a energy savings. Are they now using occupancy sensors for plug load instead?ĪSHRAE 90.1 identified computers as the original reason for the requirement.
#Ashrae 90.1 2013 manual#
No state driven reference to ASHRAE 90.1.įor California Title 24 switching half the outlet was originally by local manual switch to reduce non-essential loads on Brown out days. Personally I see this as a cowards way to justify sustainable design. This is being done on projects where most engineers are trying to get our military usable spaces with skeleton budgets. Just when you though it could not get worse on this topic. It is known these switched receptacles are not getting used. We now can only feed 6 workstations from one system furniture power line (limits of the channel space in all manufacturers). 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). Before this last mandate, I could exempt the controlled receptacles in break rooms and conference rooms from the Criteria. 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. We cannot switch them off with the sensors as ASHRAE intended. 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.
I formally submitted to ASHRAE in 2012 using the 24/7 reasoning for exempting the offices being controlled if we only had required receptacles. This locks in the receptacle controls in under federal law (EPACT 2005) for DoD facilities. FYI, The DoD has just mandated that they will follow ASHRAE 90.1 2013 for sustainability and mandatory requirements.
