Subject: Re: [obix] Energy Priorities

I personally have an issue with the philosophy that the BAS needs to understand pricing and associated financial products.  That seems incredibly complex to push that sort of sophistication all the way out to the edge.

What I think BAS should provide:
  - real-time and historical data from electrical meters
  - real-time and historical data on the major electrical load equipment
  - ability to immediately or schedule load reduction to respond to an ISO (or other) event

The BAS should understand KW (or MW) reductions.  It shouldn't need to understand how demand reductions map to pricing or rate structures.  

I believe oBIX is ideal for these functions.

oBIX members are probably as dissatisfied with the OpenADE solutions for sharing Energy Usage information as am I. But why?


If you were to have a one page description of the Energy Usage Priorities for Buildings and the Smart Grid, what would it look like?


Examples to get the thought processes running:


-          Direct live read-only access to the revenue meter entering the building (x1)

-          Direct live read-only access to the price stream for energy entering the building (x2)

-          Discovery of any other “smart systems” in the building (x3, X4)

-          Direct live read-only access to the current energy use of any other “smart systems” in the building (x1)

-          Discovery of any sub-meters in the building (x3)

-          Direct live read-only access to the sub meters in the building (x1)

-          Notification of DR event / price applying to building (x5)

-          Verification of performance under event (x5) to building ESI (x6)

-          Verification of aggregate performance under event from Building ESI to supplier (x6 or x7)


Assuming we have these items, can we put together the building system energy wish list? If we had this list, could we get it to be a SG priority?


If we did, would it come back to oBIX as


X1 – potential standard oBIX contract

X2 – EMIX, as part of EnergyInterop

X3 – WS-DD is the natural choice (to me) for discovery.

X4  - Once we do discovery, there is the profile for energy use and interaction (which may be different than, say, the device profile for Printing…what is the relationship between oBIX systems and Energy Profiles….

X5 – Energy Interop: what do oBIX systems know of Energy Interop Requests…

X6 – Tail end of standard energy contract?

X7 – Back to Energy Interoperation. May be part of an oBIX system, but likely another service….


So, that was stream of consciousness, not a proposal. What would you write…
