In fact, • Furniture is highly flexible and adjustable the secure bike parking now needs to be expanded. An estimated 80–90% of occupants travel to the building by public transit, cycling, or walking. More than 80% of Mercy Corps employees in Portland have a transit pass, and at least 10% are bike commuters. Mercy Corps subsidizes transit passes, pays half the cost for city carpool membership, limits onsite parking, and has bike storage, lockers and showers for bike commuters. Other Major Sustainable Features • Parallel dedicated outside air system and terminal fan-coil units. • Utilitarian layout with minimal private offices reduces needed square footage.
