Interesting thoughts Gardening Grandma. There are several different ideas and issues wrapped up together here, so in addition to understanding the physics involved in insulation/wind chill/draft proofing/heat transfer/summer cooling/shading/etc there are many practical considerations to take on board.
In many situations our properties benefit from the warmth direct sunshine provides, warming brick walls, or solar panels on the roof to warm water or produce electricity.
We know building construction also plays a part in controlling warming/cooling, from building a entry porch before getting to the front door to having a conservatory or lean-to against the property, double glazing, cavity wall insulation, and so on.
So, moving beyond the construction of the house, and the costs involved improving their insulation/heat loss and so on, it would be interesting to see more research on the influence of the outside environment, including our gardens, on our homes.
