Very fine, Martin! David Suzuki is very important and quite an activist
in his own right. Also, Len is one of the nicest guys on the Planet
and an accomplished permaculturist.
Used right, concrete and steel are very cost-effective and durable
building materials - concrete for foundations and floors with steel
reinforment and steel for trusses and roofing. AAC concrete for
insulation. You can actually build an entire well-insulated house
out of concrete and steel - that includes exterior and interior walls,
insulation in floor, walls and ceiling/roof, ceilings and floors.
They make AAC prestressed, steel-reinforced lightweight large panels
(8" X 4' X 18') for ceilings and floors (for a 1 stry house this could
be used as a ceiling and insulation of the roof cavity. These panels are
not overly expensive.
