Interesting question with intriguing future implications; I will look into it and advise.

I followed up with Steve Corcoran, Systems Division Consultant with Sustainble Living Innovations - the Architectual firm working on 303 Battery...

"All fixtures today are DC fixtures.  Nothing special here.  What happens when you remove AC drivers to convert AC electrical into DC to drive these fixtures it simplifies the lighting network and reduces conversion losses (AC to DC energy conversion waste).  Planning and designing a complete DC lighting system reduces capex cost as it removes the expense for AC infrastructure (panels, breakers, conduit) by running Class 2 wiring.  It also eliminates AC electrician time on site for lighting.  Overall we are seeing a 35% savings in our lighting budget using the same fixtures you would use in an AC driven solution.   The big add on for us is individual addressing of all light fixtures.  This gives us visibility to the lighting network on a per fixture basis which benefits OPEX reductions.  The DC infrastructure also supports all networks required in the building. (security, internet, public safety, access control, Wi-Fi, internet.   If we have one infrastructure to support many systems we increase our savings."

"AC courtesy plugs are required by code so there is no change here.  We hope this will change over time.   Our plan is to remove as much load off of the AC plant as possible.  Vacuums and coffee makers are low draw appliances.  We are focusing on more efficient DC driven dryers, fridges and stoves, HVAC. Our in unit AC is a custom fan coil unit from Williams.  I don’t have the details on the rating but can get it.  We are in the design stage of making this FCU DC driven as well."
