I think we need to settle on a description of "older" here. I do not consider a house from 1950 to be from the old generation of builders, but starting to be what was the budding mass building trends. The 1950s featured dirt cheap energy (also ironically, the US relied on renewables more in the 1950s than today), and so there wasn't much thought put into proper insulation because running your AC or heat all day wasn't that costly. I consider older homes to be built in an era where HVAC either didn't exist or wasn't the norm, so they were designed as such -- thicker materials, proper airflow, and ample use of shade, even considering the house orientation relative to the sunrises and sunsets in the summer to ensure the primary living quarters would be out of direct sunlight the most amount of time.
