The living building challenge was created by the Cascadia Green Building Council to guide commercial development that would be net-zero energy and net-zero water use. Based in Portland, the Oregon Sustainability Center has stepped up to the challenge as they are working to build the first high rise of its kind to follow this standard. They first approach the issue with aggressive passive design. Proper fenestration, thermal mass and natural cooling is carefully incorporated. User energy consumption will be carefully monitored with feedback and active systems to encourage the occupant’s management of energy usage.
Active solar energy production, then, is anticipated to provide the building with its net yearly energy consumption. Four separate solar panel installation systems will be incorporated into the building to maximize solar output while shading the glazing from midday solar gain. Water systems are designed to minimize consumption and maximize reuse before final treatment and discharge. Rain catchment and greywater are plumbed into the building. All excess water will be discharged by various means onsite or nearby.
