Scott Heeschen had many ‘green’ goals in mind. Together we took the approach to review, select and apply best practices recommended by Build it Green, LEED, the emerging Passive House standard and more. Certification was less important than practical design, application, detailing, and building well for effective results. 

In comparison:

– One Passive House metric is to meet the specific heating energy requirement of 4.75 k Btu/sf/yr.  Passive House Modeling for Scott’s: 4.24 k Btu/sf/yr. 

– Green Point Rating is one defacto standard for many cities around the Bay Area. Palo Alto requires a minimum of 70 points up to 150 points depending on the size of the residence. Green Point Rating for Scott’s: 239+
– LEED rating would fall just short of platinum because, among other reasons, the front door and the garage door are not fsc certified.
It can be said, in some ways, to design in sustainability was easier than the care required to build in sustainability. The Passive House standard, in particular, requires reducing air infiltration (or its opposite – air moving out of the home)  to an amount much lower than American and local practices are used to achieving. A committed builder eager to attend to details is highly recommended.
