“Pretty good house” window choices
Hi, we are in the design stage of a high efficiency retrofit and addition to an 1888 Victorian house in the Chicago suburbs. Our architect and his preferred builder are leading many of the Passive house projects in the area and are very interested in getting our project to approach those standards. Although i think it would be very cool as well, i am finding that the technical approaches and costs simply don’t justify the benefits. In doing my own research, i am leaning towards designing for “pretty good” near net-zero instead of near-passive. The house is registered as historical in the community so we will not be able to replace the entire existing siding which means the superinsulation expenses would much higher than other projects.
i have two specific questions now…
1) is a double pane window like a Zola Classic Wood (instead of triple pane Thermo Wood) appropriate for a house that is targeting 2 air changes per hour as opposed to 0.6 for PH?
2) in my own pre-bid financial modeling, i am estimating $75/sf installed price for triple pane and $62 for double pane… is this reasonable?
thanks for any guidance you can provide. I
