Last Friday was a big day at Casa Águila! San Diego County Supervisor Dianne Jacob presented a proclamation that declared May 26th, 2017 ‘Amy McQuillan and Pierre Beauregard Day’ in San Diego. San Diego Green Building Council‘s Executive Director Paulina Lis presented a LEED Platinum plaque and highlighted Casa Águila’s contribution to advancing the green building movement in San Diego. Passive House San Diego Chapter Founder Jeff Adams presented a Passive House plaque and touched on the rigorous certification system and innovation required to satisfy Passive House and LEED Platinum standards. We are extremely grateful for the support of the County, SDGBC, Passive House Chapter, and the San Diego community, and we look forward to sharing the lessons learned and sustainability strategies within this project with the community for years to come!
HIGHLIGHTS: The home is both net positive energy and water, and features innovations such as the County’s first residential blackwater recycling permit, indoor potable water use supplied solely by rainwater, and a vertical axis wind turbine.
CERTIFICATIONS: Both Passive House and Leadership in Energy and Environmental Design (LEED) are incredibly rigorous 3rd party green building certification programs. Passive House is a German energy efficiency standard that requires the home to be absolutely airtight and superinsulated while maintaining a constant flow of fresh ventilation. The architecture is designed to use solar patterns and climate to its advantage, lending to passive heating and cooling. LEED also requires exceptional energy efficiency and awards points in eight categories including site sustainability, water efficiency, and indoor air quality.
INNOVATIONS: Achieving many firsts for a residence in the region, Casa Águila is San Diego’s first Certified Passive House, received the County’s first permit for 100% residential onsite wastewater treatment, and is the first home in the area to utilize solely collected rainwater for all indoor water use. The home’s energy goals are equally as lofty, striving for eventual grid-disconnection through utilization of battery power, Solar PV, and a vertical-axis wind turbine. Also, the home features a wide array of advanced building products including Passive House Certified doors & windows, liquid membrane air sealing, Phase Change thermal energy storage, and heat recovery ventilation.
GOALS: Amy and Pierre’s goal was to build Casa Águila as a case study that demonstrates the capacity for sustainability in local residential construction. Paulina commended them for advancing our community’s conversation on reducing energy, water, and waste in construction, and emphasized the value of individual efforts and education to create a positive change within the community.
