Does green building seem to be at odds with the code?

Please encourage your building inspector to come here and participate in this Code Q&A; in the meantime, jump in with your experiences -- both positive and negative.

I had a new central air installed, and the gas line is against the flue on the heater.

My proposed wall assembly from outside to inside:

1. Ribbed steel siding
2. 3/6" fanfold battens to create air space
3. 1/2" cdx
4. 2x8 stud cavity filled with wet spray cellulose
5. 2" eps nailed to studs (interior uninterrupted rigid foam)
6. 1.5" uninsulated service cavity (created with horizontal 2x4s)
7. 3/8" acx plywood (interior wall finish)

The building is a heated workshop with some pretty high electrical needs for the machinery. Since it's not a residence, I could probably forgo the fire blocking.

Wasn't sure what category to put this in, but my situation is that I had most of the exterior of my house covered with foil-faced polyiso insulation (Rmax Thermasheath-3). The walls between the living space (bathroom, laundry, pantry, hallway) and garage did not get this treatment, but they still need insulation. I ended up with some scrap due to normal wastage, as well as some extra sheets (since we had to buy some of it by the pallet). My plan has been to cut it to fit in the stud bays and foam around to hold it in place/air-seal.

A HVAC contractor installed a Venmar HEPA 3100 HRV in my new construction home. I was wondering if it is sized correctly for my house and meets the international building code and international mechanical code requirements. HVAC Work began in 2011 but venmar was installed late 2013.

My house is:

4846 square feet with a 486 square foot attached 2 car garage. Total sq ft: 5332.
Bedrooms: 5, Bathrooms: 6..

I was ordering a new filter and noticed it was discontinued and said:

for homes up to 3100 square feet ***
*** for new construction refer to building codes.

We live in New Zealand. We want to use our home-grown cedar poles for the veranda but cannot get council approval.

We have some cedar whole tree poles. They include soft outer wood but are 25+ years old and have a minimum of 80 mm heart. They are protected from the weather by the verandas, but because I grew them on my property and they don't carry a durability and strength certification, the building inspector will not sign them off.

Help.
Cheers,
Pete

When one applies spray foam on the rim joist of above an unfinished basement is an "ignition barrier required? Will a 3 1/2" bat of mineral wool meet the requirement?

Hello,
I'm planning to build a new home on Houston city limit. I would like to build a 2500 sq/ft living space house, but for not be to hard on the budget I would like to live the live unfinished 2 bedroom. In other word take all the mechanical (AC duct, electric) to the room and noting else but just framing.
The builder told me that the city of Houston will not allow that but it also could be that the builder do not want me to save money.
Can you help me with that?

Thanks

I have a 1971Lancer double wide mobile home with hardboard exterior walls that seem to be toxic. I am sensitized to chemicals due to chronic pain and fatigue. The hardboard has a strong petrochemical aroma when the sun heats it; or when i open up the wall space, such as when working on an 120v wall box. I have been around all the other house components before (vinyl, paint, carpeting, MDF, etc) and have finally realized its the hardboard that is the main culprit.
