Earth Day is celebrating its 40th anniversary on April 22, 2010. This once-a-year event galvanizes millions of individuals across the world to help make the planet a cleaner, more sustainable, place to live.

Architects play a crucial role in this effort, helping to solve such issues as urban sprawl and density, environmental impact of building projects, energy performance of buildings, affordable housing, social equity and sustainable technology.

In his book, Sustainable Architecture in Vorarlberg, Ulrich Dangel, assistant professor of architecture at The University of Texas at Austin, discusses the regional building style in Vorarlberg, an Austrian city known for its sustainable construction methods that have culminated into a model for architecture worldwide.

Dangel will have a book signing from 6 to 8 p.m., Thursday, May 6 at Domy Books located at 913 East Ceasar Chavez, Austin, Texas.
