In the process of designing (ceileee...) my crampy home (tight space, tight budget), I find a particular setup to help me define the path of sun ray lit my roof. Its useful to examine appropriate wall height,observing the light cast through the openings or just checking which part of the house need special attention to the roof insulation (keyw*rd: heat). I did this with Autocad, thus save me time build the model in 3D for sun ray observation (you can download the .dwg file here).In my example below you'll see, half of my attic bedroom will begin to cool down at 3PM in the afternoon. Given the angle of the roof (30° angle) I certainly hope it create enough pressure difference for the air to flow to the living room and in turn expelled through another opening there.
On the left wall (6 meters height), I try to mimic a solar chimney to control overall air flow on this house (I keep eco-friendly in mind in this design). I dont know if it's gonna work at all, as the opposite wall only half its height (no heat chamber either). If you have something to say about this, I will be very glad to hear any opinion. Should it not OK, would a heat duct provide a solution? The worst case of this design is the small pathway between the wall will become a heat chamber, radiating heat into bedrooms.Ahhh, and there is another work done yesterday. I think it was too feminine in style. Do you agree? What do you think?
