I completely agree and have a solid anecdote.<p>Summer electricity bill in Texas for my previous 1600 sqft house, about $100-$150 month for cooling from Texas ambient to 74 F.<p>For our new 3200 sq ft house, we cool to 73 F, for the same cost!!!!<p>That is the difference between a late 70&#x27;s house, and modern construction, which is foam-filled up the wazoo.
