I was wondering if any of you have added dishwashers and have seen a measurable decrease in water consumption as a result. 

That means less overall consumption, etc... down we go. 

You can install two separate meters for each unit, or one meter for one unit and use the city's consumption numbers to find the difference between the two.

I bet you are spending the most money on electrical consumption. 

This is pretty much why I get a kick out the wholesale issue as a sole strategy, properties can be sold retail for the buyer's consumption.

You got the pizza, but missed alcohol consumption. http://www.webmd.com/mental-health/alcohol-abuse/news/20111013/as-economy-goes-down-drinking-goes-up

I have no plans to write book, I already write these thesis on here for public consumption.

Failing that, if each unit has it's own electrical panel, then you can sub-meter one, or both, of the panels.If the units have co-mingled electrical and share a common panel - or worse, circuits - there is no satisfactory way to bill back the electrical consumption.  

This is not information for public consumption.
