Panelists

Matt Fine
Principal, Architect, Certified Passive House Consultant at Peabody Fine Architecture
The nexus of affordable housing and high-performance building design is where Matt loves to work.
As Principal of the PFA, he leads a design and consulting team with perhaps the deepest experience of any firm in the DMV working in the realm of Passive House certified, high-performance, and Net-Zero projects. His mission is simple. Raise the standard of homes and housing by creating inspiring and healthful spaces.
Matt has a long track record with larger-scale housing projects and building typologies. Among them, Housing Up’s Harry and Jeanette Weinberg Commons was a landmark venture as the U.S.’s first multifamily retrofit project to be Passive House certified. When the 2015 PHFA pilot initiative for Passive House as an incentive in their competitive QAP was first released, Matt served as the CPHC® for the Washington Square Town Homes project, in Chambersburg, PA. The two projects combine for a total of 90 affordable dwelling units, all of which adhere to Phius design and construction standards.
Notable and more recent projects that Matt has directly designed or overseen include Housing Initiative Partnership’s Fairmount Heights Net-Zero Homes; a six-home modular-built Net-Zero community, and Phius CPHC® consulting for Habitat’s 55th Street, Passive House Duplexes, which is now under construction.
Matt’s commitment to Habitat’s mission runs deep – his direct design work with the D.C. affiliate dates to the late 2000s and includes the Phius-certified Ivy City Passive Townhomes and the EarthCraft and LEED for Homes-certified rowhouse retrofits.
Through undertaking numerous Phius and DOE ZERH-certified custom single-family home projects, Matt strives to share and apply the lessons learned in advanced building science techniques, ultra-comfortable space making, energy-independent homeownership, and durable building envelope design.
When he is not on the construction site reviewing energy-conserving builds or working on the latest custom woodcraft or landscape project, you will find Matt on the W&OD trail trying to hit a new PR for his ride to the office.
Matt is a Phius-certified CPHC® and maintains licensure to practice architecture in Washington, D.C., Maryland, and Virginia.
