The Center for Development Economics Residence Hall is the first net-zero dormitory at Williams College. Atelier Ten provided the passive solar and energy efficient design consulting necessary to meet Net Zero Energy.
Atelier Ten worked closely with the team to study every decision which uses electricity and maximizes the performance of the PV system. The building is compact and has a large surface for mounting PV panels. Daylight modeling determined the exact orientation of each dorm wing and ideal window areas. The East-West orientation allows for passive solar gain on the south in the winter to reduce the need for heating. The 2-story north-south facing wings optimize daylight while minimizing heat gain. Triple-glazed operable windows offer expansive views of the surrounding landscape, inviting students to step outdoors. Atelier Ten conducted whole building energy analysis that integrated a dedicated outdoor air system with heat recovery, ground source heat pump used for both heating and heat rejection, and efficient lighting with occupancy sensors.
