When researching building straw bale homes, we learned about passive solar energy. Our dream of building a straw bale home may have come to an end because of the cost and our small budget. We are hanging onto the hope that we can build some straw bale structures (coop/shed/barn) where ever we may move and continue to work toward our "dream straw bale home."
What is passive solar? It is the use of the sun to help meet a building's energy needs by means of architectural design such as arrangement of windows and materials such as floors that store heat, or other thermal mass. What this means is that you don't need any other heat source like propane, it uses sunlight only.
