Harvard University Science Center

For achieving the highest level of comfort with energy savings, Swegon’s VAV chilled beam technology was the perfect match for the Harvard Science Center renovation project. VAV (variable air volume) systems force heated or cooled air into rooms through ductwork that is often overhead. Swegon provided units for the renovated math classroom, professors’ offices, and the building manager’s office suite in the building. The Parasol VAV units reduced energy consumption in these areas in two ways: first, by utilizing its unoccupied mode to deliver minimum required flow when rooms are unoccupied, and second, by matching load to ventilation.

In addition to the DCV benefits, Parasol VAV also provided extra comfort by four-way blow, and the ability of the ADC vanes to individually adjust airflow patterns in each location to eliminate drafts. The on-board damper controls nozzle use to ensure induction at all turndown ratios and to prevent dumping of air even at minimum airflow rate. Swegon and sales representative DAC worked extensively with the engineering firm RFS and the Siemens branch office throughout the project to achieve the desired sequence of operations. This collaboration ensured seamless integration with the campus-wide BMS.
