Grid-tie solar electric panels
The transition to sustainability may be one of the most serious challenges facing modern civilization. But it need not be about compromise or sacrifice! We’ve put into practice what we call “sustainable prosperity”—integrating sustainable practices with a high quality of life. Here are some of the investments we’ve made at Casa Caramba on our shared path (with you!) to a more sustainable future:

Grid-tie solar electric panels: We generate more power than we consume, putting the extra into the grid, offsetting fossil fuel use.

Solar hot water and hot tub: The only way to waste hot water it is to not use it!

Insulation on exterior walls: Unheard of in San Miguel, Casa Caramba stays comfy year round.

Solar Greenhouse

Solar Greenhouse (La Calaca): Hot air in the top of the greenhouse is ducted into the home for winter heating. In summer greenhouse roof vents are open, exhausting hot air and drawing cool air into the home.

Alcohol (biofuel) stoves for winter: Made from sugar cane (vs. fossil fuel), the only emissions from clean-burning ethanol are CO2 and water.

LED lighting: More illumination, less electrical consumption.

Natural plasters: Unlike modern energy-intensive cement-based plasters, we’ve used natural cal de piedra plasters throughout.

Milk-based paints: That’s right, milk! Though not as shelf-stable as acrylic paints, they look great and wear as well as any synthetic-based paint.


Green Roof
Green roof: The upper level patios are planted with flowers, vegetables and fruit trees.

Composting: Both kitchen waste and garden residues are recycled back into the garden, eliminating the need for chemical fertilizers.

Rainwater Harvesting: Rainwater is collected from all roof surfaces and stored in a large cistern below the central courtyard. Stored rainwater is used to water rooftop garden plants.
