In the energy saving advice, especially for reducing heat loss, the air
envelope around a building doesn't seem to be under consideration much.
i.e. at the top of a hill or well sheltered the advice is the same. So
should tree and bush planting be used next to a cold north or east wall
to reduce the wind chill factor? (Increase roughness in the aerodynamic
sense). Also people who know their aerodynamics may be able to locate a
well placed defector or two for the same effect, as they would for a
racing car spoiler. Artificial plants may be used instead, and always
bear in mind fire risk. Traditionally houses can have wisteria or ivy.
Dampness on an external wall can be worse than cold air, fortunately
where I live, unlike the west of Britain, the walls aren't saturated for
months at a time.
Basically after quick wins with a fast payback since natural gas is GBP
0.17/kWh (USD 0.20), and electricity GBP 0.52/ kWh (USD 0.61).
Another thing which can be done is increase clutter on the outside wall.
e.g. lean-to greenhouse or grow house. Internally I am going to arrange
my rooms so the wardrobes and bookcases are against outside walls.
