Zero Net Energy Performance – Verification Lessons

A case study will be presented by the project’s design Engineer to highlight the sustainable technologies incorporated into the zero-net energy designed Unisphere facility in Silver Spring, Maryland. Post-occupancy energy data illustrating how the building performed and ultimately met its zero-energy goal will be presented. Opened in late 2018 and verified as LEED Zero in 2020, the building became the largest, site-powered, commercially verified zero net energy building in the country. The presentation will include analysis of detailed energy metering data which highlights which technologies exceeded expectations and which ones underperformed. Lessons learned from the overall design, construction and verification efforts will be shared. Attendees of this presentation will learn 1) the general challenges associated with zero net energy design, 2) strategies and technologies to consider for incorporation into high performance buildings based on verified energy metering data, 3) lessons learned on design, construction and post-occupancy metering of high-performance facilities.

Jason Fierko is a Principal, mechanical engineer, and energy modeler at EwingCole, a national leader in architecture, engineering, interior design, planning and sustainable design. With twenty-years of experience, he specializes in energy efficient and zero-net energy designs. He received his undergraduate degree in Architectural Engineering and Masters of Engineering Management from Drexel University. He is an instrumental participant in EwingCole's sustainability group and has been involved with several LEED Certified and zero-net energy projects. He speaks regularly on LEED certification, energy modeling, zero net energy and building energy use reduction strategies. He works with integrated architecture, engineering, lighting, and interior design project teams. He recently presented “Urban Net Zero Energy – It is Possible” at Greenbuild International in 2019 and “Integration Strategies in Net Zero and High-Performance Facilities” at the AEE World Energy Conference in 2019.
