"The windows are one of the most expensive features,"
The obvious follow-up is what the 80/20 might be on these features. If going with readily available double-pane windows shaves $10,000 off the cost, it may be a decent trade-off - maybe use that money to buy some solar panels instead, aiming for net-zero?
- dsr_ 12y agoEven the best available windows are not very good. My not-very-special house has R-17 walls; expensive triple panes windows can go to U-0.15. U values are 1/R values, so that's a whopping R-6. If your roof is in good condition, points the right direction and is unobstructed by trees, solar power is probably a better economic bet than replacing decent windows with super-windows.
