Today it is known with certainly that solar energy is necessary for selfreproduction of phototrophs.
The thermal mass in superinsulated housing is not able to store all this solar energy, so the useful solar gains are greatly reduced.
In summer, there would be sufficient solar energy to meet the hot water demand for the centre.
Accepting that energy has to be conserved, this proves that the fog explosions are, indirectly, driven by solar energy.
Efficiency was therefore conserved, to a degree, while canopies reduced the solar energy they intercepted.
Equating the average solar energy input over a longish period with an average heating load is overoptimistic.
However, high latitude locations can benefit from solar energy for a longer period than the southerly regions because of the longer heating season.
In winter, some solar energy can be utilized, but the boiler will provide most heating energy for hot water.
