This house was built as a part of the Living Building Challenge, in order to make the most sustainable, energy efficient house.
What Is The Living Building Challenge?
The Living Building Challenge is the world’s most rigorous performance standard of sustainability in building today. This is done to close the gap between current limits and ideal solutions in the building industry.
The Living building challenge is judged by seven factors, also called petals.
- This petals purpose is to articulate the importance of where a house is built, how to protect and restore the area once it is developed, and focus on local communities and agriculture
A house must be net positive for water use, meaning it takes all water precipitation or other natural close-loop water systems. All stormwater, grey and black water must be treated and managed on site.
All of the houses energy must come from on-site renewable energy, without the use of combustion.
- HEALTH AND HAPPINESS
The Health and Happiness petal is meant to focus on the importance creating a robust and healthy spaces for people to live in.
It is required to use all non-toxic, ecologically restorative, and socially equitable materials. There is a strict list of common materials that are prohibited. 25% or more of materials budget must be within 500 kilometers of the project, additional 30% of the material budget from 1000 kilometers from the project or closer, an additional 25% of materials budget can come from 5000 kilometers away, and 25% of materials can com from anywhere.
This petal is focused on creating an inclusive sense of community that embraces all sectors of humanity with equal treatment and dignity.
- The project must include and integrate meaningful art and design features to celebrate culture and for human enjoyment.
The Desert House is one of twenty houses in the world to fulfill the Living Building Challenge full living certification.
For the insulation of the Desert House ECI Used blown-in cellulose for the walls, creating not only a barrier for heat but a good sound barrier as well. For the roof we applied layers of spray foam to create a tight seal.
After the insulation was in place, the house was inspected with thermal imaging cameras to see how well insulated the house actually is. The insulation at the Desert Rain House was over the top and well above standard. Because of this, the thermal imaging revealed little to no areas of concern.
ECI is proud to be a part of this amazing local achievement here in Bend Oregon. There are links to find out more about the Desert Rain House and the Living building challenge.
