Some of the luxury  homes I am rating have features that can use additional energy, but may or may not be outside of the thermal envelope.

I would like to have a document to give the designer that clearly states how I would account for these in a rating.  I also want to give an accurate and honest rating and discourage energy-hogging features.

In some cases, there is a question of whether or not an area is part of the thermal envelope.  For the sake of discussion, let me give some examples of what I have run into, or could run into in the future:

- an outdoor swimming pool that is heated by the boiler that provides the home's indoor heat and DHW heat.

- an attached garage with its own zone for in-floor heat.

- an attached multi-season porch with its own zone for in-floor heat

- a basement storage area that is under an outdoor porch floor.  No heat source and separated from basement by insulated wall and door.

- driveway snow melt system (I haven't run into that one yet, but it could happen)

 

Frankly, I'm going to be the bad guy here and I don't want it to sound like its just my opinion.

 

Advice anyone?

You have 5 items.

# 4 is obviously outside the Thermal Enclosure

# 5 should have its own source of heat and would be a non-rated item; if it shares a heat source then it is up to your provider

The rest need a decision by your provider. Perhaps even RESNET.

I don't have any good advice, but my opinion is that the owners of homes with obvious energy waste "just because I want it" need to include the usage in the rating, and compensate otherwise if they want a reasonable rating.  Energy use is energy use no matter where it is used.

A couple that I've seen (on the same house): N. gas space heater on a screened porch and a 250K BTU patio heater. 

And the most ridiculous one that I've read about (so far): air conditioned open patio, along with two patio heaters at the "Vision House".

So, there are at least two bad guys so far...
