This article describes the construction and energy features of a low-budget passive solar home constructed in San Miguel de Allende Mexico.
We describe cost and design trade-offs made by the owner-builder Denise Gelpi Aughtman, a doctor of oriental medicine and acupuncture who practices in Mexico. The home is functional, occupied, has extremely low operating costs, and like most solar home projects, Aughtman has more improvements in the works. Our page top photo shows windows admitting morning solar gain in this nearly-balanced-energy passive solar home in San Miguel de Allende, Guanajuato, Mexico.

Like many homeowners who are attracted to homes designed to make use of renewable energy, Denise Aughtman, the owner-builder of the home described here could not approach her project with a fat wallet.
The modest passive solar design house described in this article provides a real-world example of a working solar home built on a shoestring and operated on a thread. Sited with a beautiful view of the mountains above San Miguel de Allende, and located a few kilometers outside of town, this modest home needed to provide shelter, beauty, and economy without breaking the bank.

Onsite Waste Disposal - Passive Solar Home Septic System in San Miguel de Allende
Graywater from the kitchen sink and bathroom shower/tub and sink as well as from a laundry is routed outside to a simple surface channel cut into the soil where it waters ornamental plants, fruit trees, and a vegetable garden.
While a professionally designed graywater system makes use of filtering, Aughtman's budget did not provide for a graywater holding tank, filtration, and a pump. Instead she makes sure that soaps used in the home are low-nitrate, low phosphate, biodegradable products. Washing machine drainage is passed through a simple external laundry filter to remove lint.
See GREYWATER SYSTEMS for design and maintenance details for graywater treatment/disposal systems.
Composting Food Waste at a Passive Solar Home
Simply put, when outdoor temperatures vary roughly the same amount above and below the human comfort zone (65 degF to 70 degF) then in principle, a passive solar home should need almost no additional energy source to provide heating and cooling. Our table of average weather conditions in San Miguel de Allende (below) shows that in that climate, while daytime highs are not much above the comfort point of 78 degF., nighttime lows average 26 degF below that number: solar heating of a thermal mass in the building is wanted for night time indoor comfort. (This information with other weather comments is also at WEATHER in SAN MIGUEL de ALLENDE).
At THERMAL MASS in buildings we describe a second home in this climate and we report that its typical morning low temperature in the coldest months falls to about 61 degF inside that home when no heating source is provided other than the daytime-warmed thermal mass of the building's masonry walls and roof.
1. Other San Miguel de Allende weather estimates including average high and low temperatures and rainfall vary slightly around these temperature and rainfall estimates. On average the warmest month in San Miguel de Allende is May, the coolest month in San Miguel de Allende is January, and the wettest month in San Miguel de Allende is July.
