Sustainable Energy: Thermal Banking Greenhouse Design

by admin on February 5, 2011


Steven Schwen of Earthen Path Organic Farm (Lake City, Minnesota) has built an innovative greenhouse that allows him to extend his growing season while reducing energy costs. SARE’s Farmer-Rancher Grants program provided critical assistance for Schwen in the beginning phases of his project.

@Annafin62 Working with solar energy has been done for a long time, so not surprising you were doing something similar 27 years ago. It seems every little bit helps, especially when you’re working in very cold climates.

We had some sort of solar greenhouse project in Finland, too. It was not this ambitious. Just a narrow area at the sunny side of the greenhouse filled with blackpainted barrels. In the evening the vents from that narrow space were opened to the green house. It also added to the growing season, but not much. Was it 2 weeks or a month? Sorry that I don“t remember exactly. It was 27 years ago.
