The 20 by 2020 Challenge is a local campaign to promote the development of 20 Passive House or net zero energy projects of 20,000 square feet or larger in King County by the year 2020 next year! The good news is that Zero Net Carbon buildings can make economic sense today. Passive House construction is a cost-effective means to revolutionize building energy performance, particularly for larger buildings. Many of the pioneering Passive House buildings in the US have been affordable housing projects. By establishing an ambitious energy target and using science-based design and modeling, Passive House buildings reduce energy consumption by as much as 75%. Couple this with rooftop solar or a contract for green power, and you’ve got a Zero Net Carbon building.
The 20 by 2020 Building Challenge will provide “proof of concept” that Passive House can propel our shift to a carbon-sustainable future. Passive House is the world’s leading standard for energy efficient construction. It combines building enclosure efficiency and passive solar strategies in a system for designing and building cost effective, comfortable, energy efficient buildings.
The major components of a Passive House include:
- Super-insulated envelope
- Ultra-high-performance windows
- Airtight construction (0.6 air changes / hr at 50 Pascals)
- Eliminating or reducing thermal bridging
- Heat-recovery ventilation
- Using passive heat sources (solar of course, but also equipment, lighting, and occupants).

Mighty House Construction’s latest detached auxiliary dwelling unit (DADU) includes WalkGreen® FSC Certified Cumaru Decking. Cumaru Decking is among the most resilient natural untreated decking materials available on the market today. Supplied by Green Home Solutions, Cumaru is a highly dense exotic hardwood that has a warm honey brown color with beautiful grain. Cumaru, also known as Brazilian Chestnut or Brazilian Teak, can be left untreated to age to a nice silver-grey or oiled to retain its warm brown color.
Widely recognized as the global “gold standard” for responsible forestry practices, Forest Stewardship Council ® (FSC) Certified products are sustainably harvested and ensure eco-friendly and economically viable forestry practices. The FSC Decking is one of the top decking products available in the market in terms of its strength, stability, durability and natural resistance to the elements. The FSC Decking does not contain any harmful chemicals or risk of contaminating water sources.
Decks are fantastic ways to maximize outdoor life in the NW! Mighty House Construction builds everything from backyard porches to decks large enough to celebrate all of life’s milestones.

“Located on city-owned land, it is one of nine tiny-house villages in Seattle that serve as emergency shelters for the city’s homeless population. It is operated by the Low Income Housing Institute, which develops and operates housing for low-income and homeless people in Washington state. Each house costs about $2,500 to build, and the labor is mostly provided by volunteers.”
JLC Live is the only regional trade event in the Pacific Northwest for builders, remodelers, contractors and their crews. And this year, they’re partnering with the Northwest EcoBuilding Guild to go green and high performance! The event showcases over 70 building product manufacturers, including, 5 LIVE building clinics and over 40 conference sessions, all led by nationally recognized experts who are available to sharpen both business and job site skills. Join us at the conference to learn about efficient heat, and on the expo floor to see a live demo of high performance durable buildings!
Big Heat for a Small Footprint, presented by Laura Elfline | Friday, November 30, 10:00 AM to 11:30 AM
A discussion of innovative heating solutions for small and multi-use spaces such as backyard cottages, ADUs, and compact townhomes. Hybrid heating solutions that are a super comfortable and healthy while saving space, are often also less expensive to install, and treading lightly on the environment.
High Performance Building Clinic – November 29 – 30, 9:30 AM to 4:30 PM
Representatives of the Northwest EcoBuilding Guild go start to finish on a low-carbon footprint building envelope that will last a century or more. This multi-day live building clinic, will educate attendees on the how-to details of high performance buildings. NWEBG Leaders, this clinic will consist of building a demo tiny house while showcasing carbon negative and innovative non-toxic materials. We will cover interior and exterior insulation, airtightness and waterproofing, heating and ventilation, as well as durable and sustainable finish options. The Guild empowers people through education to transform the built environment for long term sustainability.
