Cities are not green

How can the "experts" continue to say living in high density is the "green" way versus living in towns? I just attended a town meeting. Our town is staying under budget. Our town taxes in total average one half to one quarter that of cities.

Cities, not towns are going bankrupt or raising their taxes some as much as 78%!

Cool roofs and solar PV panels

Does anyone know of studies on the effect of PV panels on the rooftop solar heat gain calculation? I imagine there's some shading, some absorption and emittance from the dark colored panels, and overall a small effect due to surface area, but haven't seen any studies...

Can I spray foam the inside skirting of my house?

I am trying to keep my water tanks from freezing - my water tanks are under the house. Would the house shift from this? The house is sitting on wood pads.

Dan, we need a new Category

Dan, we need a category added. We at least I care deeply about true sustainability that is Planet wide.

Sustainability- is my choice for this category. Or it could be Rebuiding our communities to be productive sustainable places to live our lives and for all future inhabitants of Earth. OK, I need an editor....

Under Sustainability I would post this discussion;

Sustainable community entities.

Hello, I am considering a whole-house dehumidifier and was wondering if there are any health concerns regarding pressurizing a home.

I am on the tail end of a large renovation project. The house has spray foam top bottom and sides. If I don't need an hrv/erv all the better, I am mainly interested in adequate fresh air and lowering the RH. I am in Massachusetts. Thanks for any help/comments

Flat Roof insulation Question No. 2

I have a client who has had problems with blown in insulation so that's not an option for our flat roof. Might we substitute rigid foam board on the underside of the roof sheathing (cut to fit in our framing bays) and then fill the rest of the cavity with blown in dry cellulose (or wet). We will be using a EPDM roofing membrane atop the sheathing. And if that's a possibility what type of rigid board (foil faced or not)?

Thank You!

Socked draintile problem ?

This question from a builder in Zone 4
I found out something interesting last week. A lot of the manufactures won't warranty the socked draintile application in our area because of the soil conditions. Can we get an exclusion from this for ESTAR 3 because of this?
Doesn't make sense to me that if it is properly buried beneath 4" of aggregate and below the top of the footing that the soil condition should matter?
