Inspiration "The era of harm reduction, half steps and lesser evils is behind us. As a society, we need to be bold in ways that were once unimaginable. Luckily in the building sector, we now can imagine where we need to go. In fact, we don’t need to just imagine it. We can touch, experience, learn from, and replicate it." – Denis Hayes The Bullitt Center takes cues from nature, like a living organism that incorporates simplicity and efficiency in its interconnected systems. Problem Solving The Bullitt Center is the first commercial building to achieve Living Building certification. As a market rate building, it validates the model of a high performance structure using a developer model. It also serves as a living laboratory of environmental awareness highlighting the interconnectedness of sustainable design to architecture, energy use, materials sourcing, government policy and financing. Open floors with operable floor-to-ceiling windows maximize daylight and natural ventilation; heavy-timber framing is a beautiful renewable regional material offering carbon sequestration; fully automated exterior blinds provide a dynamic, layered facade that adjusts throughout the day; and most visibly, the overhanging photovoltaic panel array on the roof provides all power for the building. Environmental Sensitivity / Net Positive Energy In order to design a building with essentially no environmental footprint, a balanced solution that combines a highly efficiency envelope and mechanical system, operable windows and exterior blinds, lighting power reductions, reductions in plug loads through technology and controls, and operational changes by building tenants. The result is a building designed to use 230,000 kWh/year, for an EUI of 16 kBtu/SF. Since opening it has actually been operating at an EUI between 10 and 11, which is well below the level of any comparable North American office building, and leading to net positive status by a significant margin. Bullitt’s heating and cooling energy needs are only about 15% of the total, and the biggest end uses in the project are office equipment and electric lighting. Together, these account for almost 2/3 of the building’s energy budget. In fact, it is net positive due to energy efficiency improvements in all things we typically plug in. Social transformation The site was chosen for its accessibility, in an area primed for economic development by Seattle’s Central Area Action Plan for strategic neighborhood improvements. The adjacent park was revitalized as part of the project into a vibrant public space, reconnecting the site to the neighborhood. Since its opening in April 2013, 6000+people have toured the building including foreign heads of state, government officials, design and engineering professionals, and students of all ages.
