While attending a United States Green Building Council (USGBC) meeting recently, someone mentioned that a local university was building to a 500 year standard. I had never heard the term prior, but the idea was all too familiar. The university was constructing buildings to last the next 500 years. This is incredibly difficult to fathom for many Americans. Our country has been inhabited by settlers for just over 500 years and no structures exist from those days. The Native Americans that lived on the land prior to settlers constructed cliff dwellings like those found in Gila National Park down in New Mexico or Colorado’s Mesa Verde National Park. Many of these have been around more than 500 years, but are not inhabited today. As a curious side note, the Los Angeles Times recently ran a story about Chinese (upward of 30 million) that live in caves today. However, structures built shortly after European settlers landed did not resemble the sturdy stone buildings in the old country.
The reason the idea is familiar stems from my time living in Europe.
