Modern urban development requires a multi-dimensional design approach to encompass energy-efficient architecture, pedestrian-friendly access to shops, entertainment, work and schools, and vibrant outdoor spaces. Using sophisticated computer-modeling, the Sustainable Design Lab at MIT combines and analyzes many elements for optimal, healthy urban environments. In this presentation, Dr. Reinhart outlines such a model based on a neighborhood proposal in Boston.
