The Exchange
A collection of spaces on the second floor where ideas and energy flow freely. The three Level 2 conference areas differ in size, meaning you always have the right amount of space for your group.
Our two wellness centers located on this floor are Flex and Flow, named for their respective uses. Our functionally designed workout space, Flex, includes best-in-class fitness equipment with day-use showers/lockers and reservable workout areas. Flow is our dedicated mediation room that can be programmed for yoga classes and individual, one-on-one workout sessions.

BUILDING SYSTEMS
HVAC
Heating provided by air-to-water heat pump, eliminating fossil fuel during moderate temperatures.
High-efficiency natural gas boilers provide heating for peak winter conditions.
Cooling is provided by air-cooled chillers, supplemented by the heat pump in cooling mode for peak summer conditions.
Ventilation
The dedicated outdoor air system (DOAS) provides 100% fresh air to office floors.
Air delivered to occupied spaces is filtered by highly effective MERV 13 filters.
The central system is sized to provide 130% of anticipated ASHRAE 62.1 ventilation requirements.
Advanced BAS
Building control system allows central HVAC system to modulate operation as well as demand-based requirements for heating, cooling, and ventilation.
