Harvard’s Allston Science & Engineering Complex, the largest project ever undertaken by Harvard, sets new standards in energy efficiency and quality of the working environments. The new 544,000 gsf complex is the cornerstone of the Allston Campus, and home of the John A. Paulson School of Engineering and Applied Sciences. Passive strategies were adopted during design wherever possible, and are supported by sophisticated HVAC equipment. Progressive design strategies were adopted to reduce demands on all energy resources. These included flexible programming, radiant heating/cooling systems, natural ventilation, advanced methods of heat recovery, roof gardens, storm water management, solar strategies, sophisticated facade systems, site remediation and daylight enhancement systems. The project was awarded LEED Platinum certification and obtained the Living Building Challenge Materials Petal certification. This project was completed in 2020.
