I went to Las Vegas this last week to attend a Building Information Modeling (BIM) Conference and as a part of the conference we had an event at the Las Vegas Springs Preserve. There’s a pretty cool collection of buildings there as well as a nice botanical garden. We only had time to tour a small area of the faculty, but buildings included: a rammed earth building, straw bail building, cooling done by evaporation towers and natural ventilation and included the UNLV entry into the solar decathlon in DC (they were awarded a second place for there efforts). We participated in a presentation about the preserve and the facilities there, then had networking session and then dinner. My wife and I had a great time. Below are photos of the facilities.
