The increased density these buildings offer is key to ending inefficient and environmentally counterproductive urban sprawl. Policies in a number of American cities encourage increased residential density and height, as well as new standards for sustainability. However, creative and sensitive responses to the design, engineering, and cost challenges posed by this complex building type are critical to its long-term acceptance and success. Two recent collaborations by Solomon Cordwell Buenz and Magnusson Klemencic Associates are examples of a collaborative multi-disciplined design approach allowing architect, engineer, and contractor to pioneer technology balancing maximum occupant comfort, sustainability, and the building’s economic viability.

Be- lieving that tall towers are a sustainable solution to urban density, John’s designs have been catalysts for the resurgence of livability in the American city.

In Chicago, 340 on the Park is the city’s first and tallest all-residential tower to achieved LEED Silver certification. In San Francisco, One Rincon Hill is establishing new height standards for residential buildings and raising green standards in the Bay Area. Both projects present architectural and engineering innovations that meet the demands of their unique sites and project goals. Moreover, they exemplify the important role of a multi-disciplined design approach to successfully shape urban public policies encouraging density and sustainability.
