I went on the San Diego Green Homes Tour this weekend, which is a two-day ticketed event that allows folks to explore “green” homes all over the San Diego region. The goal is to spread awareness about environmentally friendly design to homeowners, designers, or just curious humans - it was open to all. The houses range from being showy multi-million dollar new constructions in beach-front communities, to small semi-homesteads with modest DIY improvements.
