How We Designed Our Solar Greenhouse

This northern climate presents many design challenges, including less than one hundred frost-free days, an annual mean temperature of 4.1 degrees Celcius and summer cyclonic weather patterns (i.e. high risk of hail). We are also considered to be a moderate temperate desert as our precipitation is around 500 mm including snow. However, one of the advantages of growing food up north is the long summer days. There is no better place to observe this than in Alaska which also has an average of 100 frost free days but is renown for growing the largest vegetables in the world. Also, despite being cold in the winter, it is rarely overcast and we enjoy mostly sunny days. There are two major considerations when designing a greenhouse: heat and light.
