In 2001, the National Building Museum commissioned Kiss + Cathcart to design a hypothetical building for "Big + Green," originally exhibited at the National Building Museum in Washington DC. In collaboration with Arup Engineers, we created a design that targets new ecological, urbanistisic, and quality of life standards for tall buildings. While technologically advanced, our design is not a utopian vision but a building that has been carefully engineered to be practical and economical by the year 2020. In 2014 we updated the technological criteria to 2050, and the performance criteria to self-sustianing in operating and embodied energy - our current definition of true sustainability.
