Buildings are responsible for 40% of total energy use in the United States and 35% of our country’s carbon emissions.  Can we re-envision our homes, places of business and other buildings in ways that slash energy use, incorporate local materials and otherwise become ever more sustainable?  Yes! Join a public program at Thorne Nature Experience’s new building in Lafayette to learn about the Colorado Green Building Guild (CGBG), basics of green building technology (including through the Thorne building) and an overview of techniques, materials and local expertise available to home and business owners. Green building will also be considered in the context of land and conservation through the work of 20th century conservationist, Aldo Leopold.  A short video about the Leopold Foundation's main building - one of the top few green buildings in the world - will set the stage for the rest of the program.   This program, co-sponsored by Lafayette Open Space, CGBG, and Thorne Nature Experience, is free and open to the public.   RSVP required.    To RSVP and/or for more information, e-mail Martin Ogle at [email protected]
