Household humidity

Lots of numbers. Thermostat reads 52% humidity, HRV control reads 49% humidity. The Hobo reads 56.5% relative humidity. The sling psychrometer has wet bulb 66, dry 72, which is 76% relative humidity. So how humid is this place?

Anybody familiar with British Columbia building codes?

I am building a home in BC, and plan to use Lunos e2 for my HRV. There is a lot of stuff about ventilation and HRV in the latest code revision (Dec 2014, I believe). Is there, by any chance, anybody out there familiar with the BC codes that can tell me if I am going to experience issues trying to use the Lunos fans?

A couple things that I am concerned about (off the top of my head).

Air Sealing - Tape, Sealant?

I am looking at the articles here about air sealing and most of them provide information such as where to seal but the products are not so easily determined. I am planning on taping either the OSB Seams before house wrap with 3M All Weather tape - or possibly only taping the house wrap seams. (as long as I get the right tape that doesn't allow problems with taped horizontal seams)

Mini split in the living room: Comfortable?

I would assume that putting a mini split right in front of a couch or chair would cause discomfort from the cold air in the summer and the blowing air in the winter? Is there a rule of thumb on how far away a mini split should be located from where people will be sitting?

Anyone familiar with Insultex house wrap?

I was wondering if anyone had any thoughts on this house wrap - http://www.insultexhousewrap.com/

They appear to be making some exaggerated claims and I am not certain that the R-value claimed would be possible.

Any thoughts?

How the heck was Pittsburgh, PA named a green city?!

I need some help finding a home builder in Pittsburgh, PA (preferable southwest PA).

My husband and I have had passive solar home plans drawn up and I would really like to build with SIPs. After researching everything... it just seems like building with solar passive strategies and conventionally framing is it, is like wrapping a diamond ring in the comics.
