Other information you'd like to share: This structure is sited to benefit from solar gain in the winter months and has overhangs to limit solar gain in the summer months as well as operable window that allow passive venting in the summer months.   There is no mechanical cooling and there are no ceiling fans to move air on the main level…and yet the indoor air quality is even better than I expected.
