Sentivity Analysis

I haven't yet seen a sensitivity analysis performed for passive solar heating in the north American designs. Mark Siddall wrote in response to article by Martin Holladay, on the subject of Passivhaus Windows:

NOTE: Value engineering may suggest in some climates / economic conditions (such as those in the UK) that it is more cost effective to specify a better glazing U-value. The result being that the requirements for the opaque building fabric becomes less onerous.

I'm thinking of building attached townhouses in NYC (3 or 4 floors).

My foundation will probably be a matt foundation. I am trying to meet passive house standards. What is the best way to create a thermal break between the ground and the matt. I'm concerned. I would love to see some form of database of components, assemblies and appropriate products for Passivhaus construction.

This is a lot of hot water.

Can anyone point me to a Wood Stove/Hot Water heater with:

Outside Air Intake
Hot Water Coils

in Modern Design with a large percentage of heat going to the water?

To those who attended the 2009 Passive House conference.....

The Passive House Institute-US had made available for viewing and downloading the presentations made at the conference. I'm glad they did this-there was a lot of great information and seeing it again does make one re-energized!
