If you are not aware of what “Passive House design standards” are, you are not alone. This revolutionary style of construction does not often come up in everyday conversation. The foundations of this construction technique can be found in the 1970s to early 1980s in North America. The energy crisis of the time led to the creation of the Lo-Cal house which used less energy than other residences at the time. The first mention of a “passive house” is in the book “The Saunders-Shrewsbury House” written by American physicist William Shurcliff in 1982. Germany continued the endeavor when Dr. Wolfgang Feist improved the concept. He created the Passive House Institute in 1996 and laid the foundation for Passive House design standards.
