WARMING UP IN THE BANFF LIBRARY –A deep question, solar windows and Jane Goodall–in-one
Francis and I, were walking in the city of Kamloops BC and the town
of Banff Alberta last week. Here’s a bit of what we experienced on our
sojourn. Three of the photos are in hi resolution ~ just click to enlarge.
The solar tips were inspired by visiting the Banff Public Library.
There I found an article with the profound contemplative wisdom
of Jane Goodall.
I conclude with Ms. Goodall’s poem . . .

After an couple hours, we temporarily dropped into the Banff Public Library to get warmed up from the chilling –10 Celsius temperature and basked in the sun beaming through the south facing solarium.
~ A Solar Lesson ~
One square meter of any surface on earth receives about 1000 watts of
energy when sunrays hit it perpendicular on a clear day. Doing the math,
1 square meter equals 10.75 square feet. Hence, the 8’ x 20’ skylight of the
library (160 square feet) was receiving about 15 kilowatts of free solar
energy. This illustrates that plenty of energy is available from properly
solar oriented windows and glazing.
It doesn’t take a rocket scientist to see.
And with forethought, passive solar design can be done at little or no extra cost. After all – every building requires windows . Also, the design doesn’t necessarily have to look unusual or unique, though it may.
Here are a few important nuances:
1) Passive solar windows are simpler and lower cost than passive skylights.
2) Skylights and high clerestory windows provide privacy from nearby streets or unwanted views.
3) Windows provide wanted views , cross-ventilation and excellent cooling.
4) Skylights and clerestory windows can provide excellent overhead natural light.
5) Windows are easier to shade in the summer than skylights, by utilizing overhangs, curtains or blinds, etc.
6) Exciting new types of skylights now provide both daylight and electricity, and can automatically begin to shade when required.
7) Compared to non-solar design, passive solar buildings create a closer connection with the outdoors and in general, a much healthier environment.

A poem – by Jane Goodall
THE OLD WISDOM
When the night wind makes the pine
And the pale clouds glide across
the dark sky,
Go out, my child, go out and seek
Your soul, the Eternal I.
For all the grasses rustling at your feet
And every flaming star that glitters high
above you, close up and meet
in you: the Eternal I.
Yes, my child, go out into the world: walk
And silent, comprehending all, and by
Your soul, the Universe will know
Itself: the Eternal I.
The lovely dunes; the
The duck –and I;
One spirit moving
Beneath the sky.
