In the industrial era, home is where the carbon is. The built environment accounts for about 40% of annual CO2 emissions globally. An MIT urban and environmental study recently reported that the materials used to build a new home could generate between 15 and 100 tons of CO2eq. Meet Mike Anderson, CEO and design leader at Passive Design Solutions, a pioneer in the industry who has worked on more than 100 passive single- and multi-family home projects. A passive home design can reduce the embodied carbon footprint during construction and provide long-term energy savings that cut emissions and monthly bills. Passive Design Solutions offers downloadable passive and net-zero home plans that a certified construction professional can build.
