Sun & Shade Harvesting
Sun sculptures/calendars are a continuation of a tradition pre-dating recorded history. Click here to see ancient examples on Tumamoc Hill just west of downtown Tucson.
These markers enhance our harvest of sun and shade, making the most of these free on-site resources.
Learn the seasonally changing paths of sun and shade, then work with them to provide free, clean, and silent winter heat; summer cooling; daylight, cooking fuel, and water heating year round; and the ability to turn your home into a renewable neighborhood solar power plant.
Most of these strategies cost nothing more than more initial observation and thought time, but lead to incredible long-term savings of money, energy, and water; enhanced comfort; better health; and greater awareness of, and ability to work with your surroundings for the betterment of all, which leads to greater happiness as well.
I put in more design time to ensure the integrated relationship between my home’s windows, roof overhang, and seasonally changing sun path would work as the images above show, but that was the extent of the additional cost. Now my windows and roof are my primary air conditioner in summer and heater in winter, they work great, and everyone loves to watch the changing shadow line on the sculpture that celebrates the integrated relationships.
I show you how to do the same, while integrating these harvests with that of other on-site resources such as rainwater, greywater, condensate, wind, and more in Rainwater Harvesting for Drylands and Beyond, Volume 1, 2nd Edition. Below I share many of the resources from which I drew to create this resource, and others.
