Where practical, the Quail Manor was built to be as sustainable as possible. Lots of insulation, smart thermostats, smart irrigation, easy to turn-off unnecessary power when no one is in residence. We're plumbed for Grey Water but not taking advantage of it yet. Kind of not practical when occupancy is periodic.
I am dead certain we will be dead before any of this really pays for itself. But. Seemed like the right thing to do and was kind of fun!
So, we're heavily invested in Rainwater Harvesting and Solar Power. Follow the links below for everything there is to know about how we did it at the Quail Manor. For grins and giggles there is also a link that shows the current condition at the Quail Manor.
