[If you, like I was, are wondering what a sustainable house is/does, here's a short list:

harvests rainwater
treats sewerage
generates its own power
use resources and materials that are renewable and/or recyclable
avoids the use of toxic chemicals and poisonous substances
offers improved security
is safe
is adaptable to you as you mature
is affordable]
