HVAC equipment Fuel and Type properties inconsistencies #58

What SDD Object:Property(s) are relevant to this issue?

HVAC equipment Fuel and Type properties

Explanation of addition, revision, or clarification:

I now have the error checking in place and I'm finding a lot of mismatches and 
confusion around equipment fuel and equipment type properties.   

Proposed resolution:

In trying to sort it out, I'm going to the 2013 NR ACM as my source when I 
can't find a previous spreadsheet or email with a list of what the values 
should be.  So there will be a number of changes in these properties. When 
changed I'll run them by David and then post any changes here. 

Please provide any additional information below.

Thanks for the heads up Diane. 
Here is are some specific related item I just ran across:

FluidSystem:Type
 - Revise ChilledWaterSystem to ChilledWater

CoilHeating:FuelSource
 - Revise HotWaterSys to HotWater

About CoilHeating:FuelSource:  The Heating Source list in the NR ACM section 
5.7.6 is the authority (I think) for this property, and it combines fuels and 
sources of a heating medium and some of the values e.g. Steam and Hot Water do 
not indicate the fuel used.  I'd like to change the property to be called 
HeatingSource.  If we need to define the fuel used like electric, gas or oil we 
can have a FuelSource term also defined. 

I won't change the property name until I hear from others if that makes sense.

The SDD terms are now FluidSystem:Type  ChilledWater and CoilHeating:FuelSource 
HotWater.  The value in the SharePoint list Term column, however has to be 
decorated with a suffix because these enumerations are used multiple times and 
the suffix distinguishes each one so they can be assigned to a property 
correctly in the Properties list.  The SDD term column has the term as it 
should be used, without the suffix.  I'm in the process of assigning suffixes 
more consistently which should help.

Regarding CoilHeating:FuelSource...
As currently structured, there are two coil properties that define the coils 
principal characteristics:
Type
FuelSource

The combination of the two are intended to define all the types covered by the 
NACM.  Admittedly, there can be some redundancy with this method.  For example, 
Type=ElectricResistance and FuelSource=Electric.  This redundancy could be 
eliminated by removing ElectricResistance, which would instead be defined as 
Type=Furnace, and FuelSource=Electric. 

For coils that do not directly use fuel, such as Type=HotWater, Steam, the 
FuelSource property would not be specified or would be ignored.

I am fine with consolidating these definitions of the coil to one property, 
however, would suggest listing out the enumerations here for review before 
making this change.  Also, suggest outlining the same new property for 
CoilCooling, since currently it uses the same convention.

Regarding the second point, I am having a hard time following what the issue 
is, and sounds like it is more of an SP organizational issue than a SDD 
structure issue.  If you need input from me on this, I suggest a quick phone 
call.  Thx

As far as I can tell the values for fuel source are correct for CoilCooling and 
CoilHeating.

We have this issue straightened out.
