Alteris Solar was the local installer arm of this program and they came out a couple of weeks ago to do a roof analysis. Even though we have east and west facing roofs, their analysis showed that because our roofs are relatively flat, and we have very little shading, our production would a
ctually be pretty good. We're very excited, given that our house will be all electric.

Solar Power!
Exterior Foam Installed!
The foam was installed in two layers, staggered so the seams did not overlap, and then taped
Apparently, the strapping was the most difficult and time consuming portion of the work, given that they had to pre-drill 8 inch holes into the studs and screw each screw individually.
The strapping also helps to provide a drainage plain behind the siding to allow water to drain away from the house. I have learned that this is a good way to do siding even if there is no added insulation.

Exterior Foam Started!


Remaining is some of the detailed air sealing work that will need to fill in all the gaps by the windows, doors, at the bottom and top of the foam. Scott Sorensen (contractor) and Olaf Vollertsent (architect) have had many conversations about where to spray foam, how to seal the foam at the corners, what screws to use to attach the foam and then the strapping, etc. etc. Complicated stuff but necessary.
Construction Continues

Construction has moved quickly so that by late March/early April,, virtually all of the exterior framing and construction has been completed.
The top front dormer was completely demolished and then rebuilt with a new roof and entirely new framing and sheathing (see photos).
It's starting to look like it's supposed to, and even thought our exterior footprint is only slightly larger than our original house, it seems much larger both inside and out.
Scott and his crew work incredibly quickly, rebuilding the dormer in just a week. The site is kept incredibly clean at the end of each day and the work seems solid. We're especially pleased with some of the attention to details that have replicated the period roof and eaves.
The windows on the top dormer are especially large, primarily because of code issues and required opening height for emergency egress.
Our almost 4 year old son continues to call this our green house, and although I'd like to believe he understands what we are doing, I think it's just because the sheating is green. :)

Material Recycling Report
Thought we'd post the results of our first Construction material recycling report from E.L. Harvey. For January and February the results are:
7.97 tons of materials generated
1.20 tons of concrete diverted
5.58 tons of wood diverted
6.77 tons of material diverted
85% recycling rate
Although we are astounded at the amount of material being generated from this relatively modest project, we are excited by the efforts and reporting of E.L. Harvey, which, apparently, is one of the premier C&D recycling companies in the area. And it's great to know the results, which seems to be a unique feature from this company. And, it costs no more than normal C&D management companies. We plan to get more information about where the materials being diverted actually go.

Totally forgot to mention that a week before work began, we had a blower door test conducted by Byggmeister (http://www.byggmeister.com/), a local newton green remodeling company, as well as a HERS rating analysis. For those who know about these things, the results were:
1. 2400 CFM at 50 pascals
2. A HERS rating of 111

We plan to soon remove all the insulation from the attic (which has multiple layers of mixed types) but the weather has made things move a bit more slowly.
Several key decisions have been made, such as triple pane low-e glass fiberglass windows from Fibertec (http://www.fibertec.com/) and we're actually converting to an all electric house, including the water heater and range. This is not necessarily our first choice, but there are several reasons, some of which are more compelling than others:
1. A house that is so tight is much safer without any combustion inside the house
2. The price of electricity can only go as high as the cost of solar, while who knows what will happen with gas prices.
3. We reduce our utility billing and payment effort to just one per month.
4. We eliminate the minimum charges associated with just having gas service.
5. Since our HVAC system, which will be the highest cost energy user in the house, will be electric, it made sense to go all electric.
6. Our water usage is pretty minimal (was about 10-14 therms per month) so even with electric the cost shouldn't be that high.
We're also using E.L. Harvy to recycling our C&D waste and expect our first report from them in mid-March.
