[Strawbale] Passive Heating

[Ilan Ungar]

Hello

A short while ago I posted here for some advice on sub floor radiant
heating.
I received replies suggesting I do not need it here in Israel (5-15 Degrees
Celsius in the heating season)
and careful design will allow for  comfortable indoor temperatures.

That lead me to explore an approach of allowing sunlight in the house to
heat thermal mass surfaces.
But then I open my Architectural Graphic Standards and find that the R value
for double glazing openings is a
very poor 1.61

Sounds like this definitely rules out large areas of glass on the South
facade as these surfaces will drain all the houses heat overnight...?
Am i getting this wrong? I do see a lot of talk about this approach (the
Trombe wall effect...?)
Was the advice for "proper design" meant to direct me to other approaches of
heating without active heating systems?

Thanks. Ilan.
