Earth Day Tour - Far Out Buildings

On Wednesday, April 22 we will be leading visiting two Corvallis buildings that show us the future. Talk to the owners/builders about design, materials, costs and construction techniques for the buildings, including energy and water systems. Both buildings were made with materials and techniques that are not currently in normal practice and represent significant reductions in carbon footprint and energy/water efficiency when compared to current building practices.

Tour by bike or car-pool. Bikers will be traveling about 7 miles, including hills. 4:00 p.m. to 7:00 p.m. Identification and locations of the buildings are provided on the day of the tour to pre-registered participants. Also, meeting location in Corvallis will be provided following pre-registration. To register, contact Barbara Loeb
