It has always appeared to me that mechanical components such as boilers and heat pumps, used to be designed from a standpoint of longevity over performance, with the mindset that these componets should last lifetimes. But they never did, and even if they could, technology would pass them by. Who wants to keep an old 65% efficiency boiler for 30 years past the introduction of 90% or even 95% efficient boilers?The last project benefits from the advances in technology and efficiency using a 95% boiler for radiant heat and a 24 SEER heat pump for AC and spring and fall heat.
So, we need to consider what "better" means, when people start talking about old vs. new being "better".
The same has happened with kitchen appliances. Our mothers picked our their avacado green or mustard yellow oven/range set and dishwashers, with the mindset that they'd keep them forever. But who wanted an avocado green oven and range past 1978?
It turns out that appliances which are built as cheaply as possible, with maximized efficiency and an expected lifespan of maybe 20 years is the sweet spot. After that, they've gone out of style, anyway.
Insulation is nice, most of my house has none. But I did some comparisons ca.2012 on a bunch of my 1770's windows against Andersen's best mid-1990's products, then only 15-20 years old, and I found that the 250 year old windows actually outperformed the newer ones by a healthy margin, when fitted with a good storm window. This was done with fairly extensive thermal imaging and thermocouple measurements, both inside and out.Insulation is R50 in the ceiling and R28 in the walls. Modern doors and windows that seal up tight. An Energy Recovery ventilation system that maintains a positive pressure when burning a fire, or running appliances that vent to the outside. All recessed LED lighting, etc.
None of which is going to be native to an old house.
The older windows may draft just slightly more, but when comparing the 4" air gap formed between an old traditional double hung and an exterior storm, to the 5mm air or argon gap of any modern double-glazed window, the old phrase "there's replacement for displacement" comes to mind. You just can't beat a 4" air gap with 0.2", no matter what else you wrap around it.
? Not sure what this means. Do you mean housing inventory? Lots of old houses, depending on how you define "old", in some of our surrounding historic villages and farm land.That’s not to say that you can’t cut corners in construction, either old or new, but if you want to do things right, new is the clear winner if you want to capitalize on what’s available.
