North and South Academic Buildings Williams College
The project consists of two new academic buildings totaling 96,000 square feet and planning for a new library facility directly adjacent to the building site. The academic buildings contain faculty office space, as well as classrooms, labs, break-out and conference spaces. Each building has three floors above and one floor below grade. The buildings are fed from the Williams campus chilled water, steam, fire protection, and electric power loop systems.
Electric power is brought in at medium voltage, to a unit substation with dual-wound primary to permit future change to a higher voltage.
The buildings were designed to comply with LEED standards and optimizing energy savings through the use of systems such as operable windows for natural ventilation, exterior shading devices for south-facing windows, CO2 sensors for demand-based ventilation, day lighting controls, waterless urinals, and variable speed drives. Large centralized variable volume air systems take advantage of the large diversity in the buildings’ use. Occupancy sensors are utilized for both lighting control and control of HVAC system setbacks. Additionally, each building will have a “green roof”, covered with a species of sedum, which will moderate heat gain, reduce energy consumption, and improve site storm water management.
