RE: [GBlist] Clerestory roofs

["Ralph Bicknese" <ralph.bicknese@christnerinc.com>]

Alan:

The first low energy house I designed and had built (21 years ago) had a
shed roof with clerestory windows.  The clerestory faced south with an
appropriately sized overhang.  This is a very good concept to add solar heat
in the winter and daylighting year round.  The quality of light was very
nice.  Daylighting is most effective when light can be brought in high and
deep into a space.

There is not a tremendous amount of solar heating contribution from the
clerestory though becaus the windows were fairly small. To get more heat I
would make them bigger.  Two feet difference between "back roof" and "front
roof" is not nearly enough to have enough window. Of course all of the
glazing and the rest of the building skin, thermal mass, etc. needs to be
considered in sizing the solar collection area.

There is no paticular unusual structural problem in designing a roof of this
sort.

Cheers,
Ralph Bicknese

Subject: [GBlist] Clerestory roofs


Looking through tons of house plans trying to find something simple with
the right orientation and suchlike for my proposed building spot, I find
almost no double-shed roofs with clerestory windows between them.  This
has made me wonder whether there's some inherent disadvantage to such
construction, as opposed to "standard" roofs with a peak (or peaks).

To me, a house with a double shed roof, one say about 2' lower than the
other at the peak, and with windows between the two roofs, makes a lot of
sense.  But I'm definitely not an experience builder, so would appreciate
thoughts from those folks here who really know their stuff.
