Featured Case Study
We recently published a second case study on a Tiny Home Village, Transitional Micro-Housing at Opportunity Village Eugene which offers an interesting contrast to our earlier study, Permanent Subsidized Housing in a Light Industrial Zone at Quixote Village. We are looking for volunteer researchers to help document additional tiny home villages, and contribute to a toolkit project. Is this you?
This case study grew the Glass Aggregate Summit on November 3, 2011, which brought together 50 city, state, county and state public works staff, with architects, designers and others to discuss crushed glass cullet, which can be used for a wide range of construction, landscaping, utility and other projects as a 100% substitute for natural aggregates such as sand and pea gravel, or as a blend with natural aggregates. Read how the Housing Authority of Thurston County won approval to put glass aggregate to use to save money on this innovative project!
The Bullitt Center is a 6-story, 50,000 sq. ft. office building being constructed in downtown Seattle. When complete project owners say it "will be the greenest, most energy efficient commercial building in the world." The two case studies featured here highlight some of the elements which are helping them meet this goal.
The Pacific Northwest is a hotbed of growth for the super-efficient design standard known as Passive House, bringing us homes and buildings 80% more efficient than comparable structures. While Passive Houses breeze past energy code requirements, they pose some interesting challenges by a Mechanical code that requires heating systems sized for less-efficient homes. What if you could heat the whole house with the equivalent of a hairdryer on the coldest days? This case study explains how this code barrier was overcome...
Many code innovations are not necessarily new technologies. Many are old, or even ancient methods which have proved their worth around the world, but have been supplanted in the US by manufactured products or standardized designs. Thermal mass heaters take many forms, so as yet there are no prescriptions dictating their safe and effective use, but the Masonry Heater Association (MHA) is working on it! In this case, MHA helped the owner-builder make the case using standards developed through ASTM. The owner hopes her project will be useful to anyone embarking on a similar project, or aid building officials in approving masonry heaters. Lots of supporting info here...
The approval by the City of Portland of the environmentally superior Sanden "Eco-Cute" heatpump water heater was the first in a chain of approvals including Seattle and now Bellingham, despite the equipment not being UL Listed! After each project, the approval was documented in the Code Innovations Database, along with supporting materials that were used to justify subsequent approvals. This "cascade effect" of approvals based on published case study info, shows the power of the Code Innovations Database for making it easier to build green!
