Heyo, people of Earth! About a month and a half ago, I mentioned that I'm working on a technology that provide homeowners with an aftermarket solution to decrease home energy costs through controlling heat loss via windows.
I'm still working on that, and I'm now at a point where I need to talk to people and get feedback about what we as scientists don't take into consideration.
If you're willing to talk to me, could you please send me a DM here? THANK YOU!
@hafnia My husband and I own our home. He had his windows replaced at his old house in the name of efficiency, but the new ones were annoying and difficult to close correctly. We've found that "efficient" windows can go up OR down and sort of require slamming/forcing to get completely closed, in both houses.
A barrier to our replacing them in our current home is the cost of checking to see whether the source of heat loss is actually the windows; renting the equipment is a non-trivial activity.
@eleanorkonik This is a really interesting aspect that I had not thought of! I can see how that would present a definite barrier to entry, yup. What window solutions have you been considering, if you don't mind my asking? (I know that you need to get the measurements FIRST, but assuming that the windows are the culprit, have you thought at all about what you'd be replacing them with? :) )
@hafnia In this house we don't particularly have a draft problem, or even know if we're losing much energy, we're just vaguely interested in being energy efficient as a matter of policy. I generally leave the major house stuff to my husband (he owned a house before he met me) but I did recently insist on purchasing new blinds in order to help keep the light/heat from entering/escaping (seasonally) and we got those honeycomb kind with the metal interior that do a good job of blacking out the sun.
@hafnia I realize that's not totally what you're asking but it's the only answer I have, sorry xD
I think it's the "double-hung" windows that I detest.
@eleanorkonik This is actually really helpful to me, honestly -- we're trying to figure out what people are currently using and *why* they're currently doing it. So in your case, it sounds like it was mostly, "look, we'd love to replace the windows BUT it's costly and we're not sure it's them, SO we went with a low-tech solution that should still work but doesn't require total replacement"? :)
@hafnia Pretty much, yeah. It's not "as" good but honestly even with perfect seals on the windows the greenhouse effect would still be in play (upstairs has lots of airy windows, so it gets hot in summer) so for $5k, we got blinds instead of windows and it was probably the better choice in terms of being energy efficient.
@eleanorkonik Thank you for taking the time to answer me! :D I can absolutely understand why you'd want blinds in that situation!
@hafnia I definitely like the idea of an "aftermarket" solution that doesn't involve total window replacement, though, like a treatment one could apply to old-fashioned windows. Something like those flaps and tubes you could put on the bottoms of doors to stop drafts from doors cut to avoid scraping.
@eleanorkonik There are a few! Most of them are pretty low-tech. 3M makes a clingfilm you apply with a hairdryer; it's inexpensive and seemed to help my heating bills when I lived in a terrible ancient apartment. :)
@hafnia Oh cool! Honestly before this conversation it had never even occurred to me that something like that might exist! (We needed the blinds for privacy too, tbh)
@eleanorkonik I totally get you. The solution we're talking about providing would include opacity as well as IR reflectance (keep heat in or out depending on season). Basically very high-tech blinds. :) Still 5-10 years away from a product offering though, so...y'know. Heh.
