I'm having an elevator installed in my house
(thanks in part to the government of Quebec) but rather than put it
inside the house, I can, for a bit more, put it on the external south
facing side of the house. But, rather than just put an energy consumer
on my house, I could probably use the shaft as a solar chimney of
sorts. If I put high SHGC windows at the 3 landings and leave the brick
exposed inside the shaft as much as possible, I think the air temp
inside the shaft would be quite high in the summer. If I vent at the
top of the shaft away from the prevailing summer wind, I should get a
little help with updraft.
Every picture I've ever seen of a solar chimney shows glazing at or
above the roof line. It seems to me that the air inside the chimney
would not be heated until it was relatively high in the chimney. I
think this may be the case to prevent hot air from the chimney from
leaking back into the house at the point where the house is vented to
the chimney.
My question is; would my idea, which would probably produce
relatively high air temps inside the shaft, work to suck air out of the
house, provided, of course, that I open windows elsewhere in the house, as the air rushes to the top of the shaft, or would hot air
simply leak into the house when I try venting to the chimney. |

Sorry, no answer for you question but maybe you can help with mine.
We are building a ICF home on a lake near Oxford, MS. It will be a ranch with walkout basement. Hope to start October 1, 2008. My wife is handicaped and we are stongly considering a elevator for her to better able to reach the basement and the travel by scooter to the lake.
Any references you have for elevator companies, price, type, etc. will be appreciated.
Thanks, Dean

I assume you need access to 2 floors. If I were in your situation I would seriously consider 2 similar elevators, one made by ThysennKrupp and the other by Savaria. They are both elevators that operate without a hoistway or a machine room. Here are links, there are videos of operation of these on site.

If you have questions about these, I'll answer as best I can but I'm neither a salesman nor a customer. My needs are much different.

I'm designing something similar for a different reason. I'm building a 3 story trombe wall on the southwest corner of my house to feed hot air to the "solar sauna" I'm building on the upper wrap-around porch. This trombe room and the sauna will be completely isolated from the house itself.
In the middle of my house I'm designing a belvedere with a cupola on top to function like a solar chimney. Here the hot air of the house rises and gets an additional boostof slar gain "above" the living area, to encourage passive airflow through the house. Make-up air will be pulled into the basement from the shaded window wells on the north side of the house.
Addressing your design, I have a few concerns:
1. With the heat occuring up the full length of the shaft as with my trombe wall room, you will need to give SERIOUS consideration to how you will insulate the elevator shaft opening to prevent heat from entering your house.
2. The elevator is not likely to be insulated well, and it may function more like a sauna for those attempting to use it.
3. Can the elevator equipment (particularly hydraulics and pneumatics) withstand the presumed elevated temperatures? |
