Thermal storage walls occupy little space and are particularly effective in the winter when low sun angles strike them most directly. Sun Spaces Sun Spaces are glass rooms built onto the south side of a building to collect heat. These rooms are thermally isolated from the rest of the building so that their interiors heat quickly. Hot air from sun spaces is released directly to the building's interior by means of windows, doors, or vents. The bedroom wing of Point House is angled 30 degrees to the east.
East bedroom has a sun space to speed early morning warm up.
The attached greenhouse is a sun space that also provides a good environment for gardening. Convection Loops Convection loops use solar-heated fluids to transfer the sun's energy into a home. As sunlight heats the fluid in the collector, hot fluid naturally rises into the tank. The rising fluid siphons cooler, heavier liquid from the bottom of the tank into the collector where it is heated. This passive circulation of fluid is called thermosiphoning.
