I've talked about some of this on Mastodon before, such as creating #coroplast and #blackout material #WindowBlocks to prevent the heat from our long 53°N summer days getting into my unit (circa 2021) or adding thermal window film to reduce heat even more (circa 2025) without simultaneously creating a dark and depressing #bunker-effect for the entire summer. Doing all of this required various materials, time and of course, money. While all these (and other) mitigations were experiemented with and created/installed over several years, which spread out the up-front cost, the irony is not lost on me that these approaches have culmulatively cost as much as as least two in-window #AirConditoners would. 🙄 9x #heat #ExtremeHeat #mitigation #HeatMitigation #LifeSafety #cost
