Croxton Collaborative Architects, PC is a full- service planning, architecture and interior design firm. In addition to their well-known design ability, recognized AIA Honor Award for Design Excellence, Croxton Collaborative Architects has originated and developed much of the practice of environment / sustainable and human-centered architecture and design. As an internationally recognized innovator, they have defined the criteria that are used to establish universally accepted goals and practices in this field of sustainable development or "green" architecture. Their first, full spectrum, environment informed project for the Natural Resources Defense Council Headquarters (NRDC) stands today as the seminal project, proving that to be 'environmental', a project must address the full ecology of the building. NRDC, after a year of grant-funded monitoring by Con Edison, proved cutting energy consumption in half. Croxton Collaborative achieves its unique level of performance through balancing the art and science of architecture the use of customized simulation tools, renewables and day-lighting systems, advanced knowledge and understanding of air quality parameters, materials conservation and sustainable waste stream management. All of these tools are used to achieve the ultimate goal: to create an optimum interaction between built environment and natural systems and to reconnect people to natural assets: full spectrum light and maximum fresh air. The key to the firm's results is in having harvested performance results and criteria verification for more than twelve years, greatly enhancing the 'in-puts' to their simulations. Improving the environment with well-designed architecture and reducing pollution and creating a sustainable future.
