As I battle with an hvac solution for our home, we are leaning more and more towards trying to reduce the load further. I'll mention some details of my own house a bit below but I'm actually asking in hopes of a more generalized discussion of what a reasonable retrofit btu and ACH50 goal is.
I did some reading tonight in the hopes of answering this question but didn't find any useful rules of thumb. I know, the old HVAC rules of thumb have caused a lot of grief. I'm not asking for a rule of thumb about BTUs/sf for heat but rather what is rationally achievable in a retrofit scenario.
