[Greenbuilding] Just an update

[Alan Abrams]

Lynelle-

Congrats on the house.  One hundred questions come to mind.  Such as:
What region are you?
What are the average HDD's and CDD's for your location?
What is the floor area of the house?
Can you isolate the KW's and or BTU's used for heating and cooling for given
periods?
Did you do a blower door test on the house after completion?  Do you use
heat recovery ventilation?
Does the house rely on solar heat gain and or solar shading?  Any other
consideration of window location and solar exposure?
What sort of glazing did you use?

regards-
AA
