I have a customer very concerned about limiting her family's exposure to terpene VOC's.

We're about to build the customer a new, 2-story house. At present, we're intending to build 2x6 wall frame with cavity walls filled with either cellulose or open-cell foam.

Any other observations about terpene sensitivity, or means of encapsulating terpene inside framing lumber would be greatly appreciated.

Also, do you think a typical layer of open cell foam under the roof deck will actually serve to encapsulate the terpenes in roof framing and decking members.

Costs and energy savings for new construction

I'm meeting with the some people from our state's CID next week to talk about the costs of energy efficiency upgrades for new construction for when you go above and beyond code.

Have condos gone green?

Do you know of any examples of condo managers or HOA's retrofitting existing condos for increased efficiency and sustainability? I'm interested in projects that have included more than just swapping out lightbulbs.

Thanks for any information you might have.

How can I quantify the heat loss of brick masonry fire place?

I am trying to convince the owners of a small 800 sq ft cottage that the existing brick fire place should be removed as it will always be an out of control heat and cold conductor along with moisture transference and hard to seal air gaps in damper and contact with the wood structure. Fire places are now illegal where the house is anyway so it will never be used as one.
A blower door and infrared shows the air infiltration but not the daily, seasonally, hot and cold and moisture fluctuations.

What is the best way to cool an atrium in the summer?

I conducted an energy audit on a 1600 sq ft earth contact home with an atrium. The room is 6x14 with a brick thermal-mass floor, south facing glazing and about 9 sq ft of skylights. Four grilles along the bottom interior wall and 4 registers at the top circulate air in the winter to the home. Conducting a blower door test I found out this small room leaks air at the rate of 1000 cfm. The pine board ceiling is connected to the attic. The AC runs continuously during the summer.

Is installing cedar trim boards on top of bevel cedar siding a new way of letting the walls breathe?

I have a customer who just moved into this house and the inside,outside, and window trim boards are on top of the bevel cedar siding.I advised him that there is air infiltration and places for bugs. Another contractor told him it is the new way to let your walls breathe. I don't think it is, I would like some feedback. Thanks
