Description
Dillon House, Harvard Business School — EnerPHit certification, design-stage review
Dillon House is a three‑storey, 5,800 ft² administrative building at Harvard Business School, home to the MBA Admissions office. Designed in Georgian‑Revival style as part of the original campus plan and ultimately constructed in 1965, the building’s cultural value and façade character were central constraints for the retrofit strategy.
RDH Building Science led the Passive House design consulting for the project. Praxis was appointed by designLAB architects as the Passivhaus Certifier.
Our Design Stage Review identified design strategies to meet EnerPHit+I Component Method certification. We also provided recommendations for alternative certification pathways, given that planning restrictions and cost constraints presented challenges for compliance with the EnerPHit Component and Primary Energy targets…for example, EnerPHit Step‑by‑Step: an approach that pre‑certifies the first retrofit phase against a comprehensive EnerPHit Retrofit Plan (ERP), with full certification upon completion of all planned steps (after achieving ≥ 20% reduction in PE/PER or demand in the first step).
