 Okay, we want to start looking at the windows and the doors See what kind of shape they're in. I noticed that the windows are all in pretty good shape They're all double-pain. They have storms the ones that don't have double pains have storms on The one thing I am seeing though is if you notice down along the bottom here, it looks like there has been some moisture here That indicates to me that even though the windows and doors are probably in pretty good shape The house is probably fairly tight. I think if we run a blower door test, we'd find This house was probably under the limits. We'd want to see as far as air exchange So we would want to make sure to address that during our audit is Run a blower door test and see how tight the house is and what we want to maybe look at then is Check ventilation in the house. We may want to think about adding some air to air heat, you know heat exchangers Some of that type of thing like I said the windows and the doors all seem fairly new Good double-pain, which is the bare minimum you want to see, you know the triple-pain is better But the doors and windows are all weather this weather stripping and the glass or what they what they should be so We wouldn't have to really do any work on those
