Heron Hall is a Benchmark for Future Generations

Planning has come to fruition and the challenge of building Heron Hall, Jason McLennan’sleading edge green project and Living Building homeon Bainbridge Island, WA is in full swing.

Read more about Jason and the project below:

RainBank Rainwater Collection Systems principal Ken Blair is pleased to bea member ofthe Engineering and Consultant Team for Jason McLennan’s Heron Hall, aliving building homeMcLennan is the CEO of the International Living Future Institute, a non profit organization behind the world’s most progressive and stringent green building guidance system. He is the creator ofthe Living Building Challenge and heads Cascadia Green Building Council, the Pacific Northwest chapter for the US Green Building Council and the Canada Green Building Council.

Jason speaks about the living building challenge:

McLennan states, “it’s not enough for architects, construction companies, and real estate management companies to focus on reducing their environmental impact.The time is right to be far more ambitious, think instead about recharging and replenishing our planet“, explains Jason.

Heron Hall and Bullitt Center Take on Living Building Challenge

1 Comment


Close-up of a worn, metallic fountain pen nib on a black surface.Chances are if you’re from Seattle you have heard of the Bullitt Center. According to its website, “The Bullitt Center was designed to show what’s possible today, changing the way people think about high performance green building.”

One of the most ambitious aspects of the Bullitt Center was to achievethe goals of the Living Building Challenge,created by CEO Jason McLennan in 2006 and encourages eco-centric design. The Living Building Challenge carriesthe strictest green building requirements in the industry.

Close-up of a worn, metallic fountain pen nib on a black surface.Now McLennan is building his own home, Heron Hall, incorporating the same design challenges as the Bullitt Center. Heron Hall’s whole house water system is sole source, meaning that rainwater is the only source of water. The water system was designed by 2020 Engineering with RainBank Rainwater Systems as a consultanttothe design team. RainBank was contracted to construct the 15,000 Gallon Contain Water Systems tankcistern and now is looking forward to building the filtration and pumping system.

McLennan recently published a blog post about the cistern build, which was completed last week. RainBank’s Engineer, Chad Lindsly, along with president Ken Blair are working on the finaldetails of the system’s components and will be installing that portion of the system soon.

Stay tuned for updates on this exciting project.

New Seattle Homeowners Can Save Big Bucks


A metal-roofed, cone-shaped greenhouse surrounded by greenery.Do you know that by installing a rainwater collection system for toilet flushing and laundry facility, Seattle homeowners can save big buckson their water and sewer bill? Considering the expected price increases over the next 5 – 10 years on these utilities, a return on investment is a reasonable expectation.

A study by the American Water Works Association to determine end use of water in 100 single family homes was conducted back in 1999. Even though the study is dated, it is a good indicator of average single family usage with regard to rainwater collection.

The study foundthat 27.7 % total household use of water is used in toilet flushing and 20.9% total household water use is by laundry facility. These uses can be improved by low usage fixtures such as dual flush toilets and front load washers, however, they do indicate an average of 48.6 % water consumption by these two fixtures.

New home construction in the Seattle area is required to mitigate roof runoff onimpervious surfaces on site. Costs of infiltration can be expensive. A well-designed and installed rainwater catchment system uses this runoff water for domestic use rather than infiltration. By redirecting the costs of infiltration design and construction and considering the savings on water and sewer bills, the average Seattle home owner can see a significant cost savings as well as a return on investment.

With all of the news about aging water systems, poisoned and tainted public water, conservation and sustainability, isn’t it time to design and build your rainwater collection system?
