    I dont understand this, retro fitting homes.

    An oil furnace usually means old steam pipes, so that means gutting walls to instal new copper heating lines. Re insulating can also mean gutting walls, while replacing old windows. And since were gutting walls replacing older wiring is a good call, 1/2 inch copper water feeds should be replaced with 3/4 inch copper, old cast iron drains need to be replaced with PVC.

    Yes, this work is labor intensive, so is the price tag- 100k+.

    New windows and doors for the most part eliminates weatherstripping. Frankly anyone who mentions weatherstripping in the same sentence as replacing windows demonstrates a fundamental lack of understanding of how this works.

    A house built around 1970 might have come with gas hot water heating and aluminum framed windows, this is a good target, the original furnace had an efficiency of 70%, and by the 1980's new furnaces were up to 84%, Now up to 90%+  many in fact have been upgraded.

    Aluminum framed windows, many also have been replaced.

    Your targets are homes that are 40 years old or younger:
    As a general rule of thumb, if you can replace a gas hot water furnace that is 15% more efficient than the one replaced, with no work on copper feed lines, just the furnace swap out, youre looking at a project that easily pays for itself in savings within 3-5 years.

    Homes 40 years or younger, that were insulated properly, but have old style windows, do it.

    •  um, no (8+ / 0-)

      Once upon a time I purchased a multi-unit rental complex with cement block walls (R value = 1!) in a cold winter area, where the landlord (=me) was obligated to pay for heat.  First order of business was to insulate the interior side of the walls, properly finished with drywall instead of painted over cement.  Project paid for itself the first season, and cost an order of magnitude less than your estimate. Heating bills were reduced by a factor of 3.

    •  What should be done in a given house varies (6+ / 0-)

      by the specific house.  Some houses a better candidates than others.

      Weather Stripping is not in conflict with replacing windows.  Some houses might get weather stripping, others get new windows, and some doors would still need weather stripping.

      Replacing wiring and plumbing would be for the homeowner to pay for and finance.  Some may want to do this is that while the other work is being done, the incremental cost would be lower.

      The targets are for a single home, what can be done for $20,000 or less that has immediate returns of 20% or more?

      The most important way to protect the environment is not to have more than one child.

        I see targets as single family homes newer than 1965.

        Returns of 20% annually? SO the savings would have to pay for itself in 5 yrs or less. Good.

        That leaves out a lotta homes, but avoiding money pit homes is vital.
