Building sustainable office towers doesn't end with design, construction and commissioning. Building sustainably represents an ongoing commitment to learning how buildings function in an everyday sense. Tenants change, use demands continuously evolve, and it is up to the building team to adapt to these increasingly nuanced conditions. The Bank of America Tower at One Bryant Park demonstrates the complexities of sustainable design and ongoing efforts to improve energy efficiency in a modern office tower. T his 55-story tower was conceived, designed and built to be a nucleus for banking and commerce. Situated in the heart of Midtown Manhattan, One Bryant Park marries some of the world's highest-intensity office users with a highly efficient and sustainable design. With nearly 500,000 ft2 of trading floors and nearly 10,000 occupants a day, One Bryant Park buzzes with activity seven days a week, 24 hours a day. 50 The building consumes a lot of energy with a site energy use intensity in 2012 of 211 kBtu/ft2, which is the highest among similarly used and sized buildings in New York City. However, can One Bryant Park's energy consumption be fully described by looking just at site EUI? This article discusses the actual, asoperated energy performance of One Bryant Park by looking at one of the largest energy users: the ventilation system. Going down the "rabbit hole" HIGH PERFORMING BUILDINGS Summer 2014 and chasing best energy performance demonstrates how One Bryant Park maximizes efficiency through the ongoing refinement and improvement of building systems at every level of operation. Down the Ventilation "Rabbit Hole" To see how complex it is to improve energy efficiency after a building has been occupied, let's look at what happened when the One
