It’s better late than never…..so we would like to share with you the work of CAST Architecture, a local Seattle firm who presented their new project, In-Freemont, at Northwest EcoBuilding Guild’s 10×10x10 event on September 25.  The Northwest EcoBuilding Guild, an alliance of builders, designers, suppliers, homeowners, and partners concerned with ecological building in the Pacific Northwest, hosts the 10×10x10 event every year to introduce ten cutting-edge sustainable building projects in and around Seattle.

CAST Architecture’s project, In-Freemont, is a set of 5 BuiltGreen town homes finished this past spring just north of 36th in Fremont on Phinney Ave.  MAP THIS Project. 

In 2007, CAST recieved a Built Green grant in the multi-family category, in the hopes of pushing a project like this forward.  They were successful with the help of a client who was willing and excited to explore what could be done in terms of a high quality sustainably minded project.

Some of the features that make this project sustainably innovative are:

R-24 walls made of a composite system of spray foam & fiberglass batts

Gas boiler to drive the radiant floors and domestic hot water at a 93% efficiency rating

Solar hot water plumbing, which would preheat the domestic hot water loop for the boiler

Heat recovery ventilators to bring in fresh air while recovering aprox 80% of the embodied energy 

Garage exhaust fan equipped with a motion sensor

24”oc studs on 75% of walls to reduce thermal bridging

R-50 roof with insulation heal on truss

CAST Architecture was also honored with AIA Seattle’s 2009 Regional Top 10 Award for  What Makes It Green?
