Re: [obix] Energy Priorities

[Brian Frank <brian.tridium@gmail.com>]

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�
