Sustainable design principles have always been at the heart of our design decisions, particularly when it comes to natural ventilation, passive solar strategies, light, views and material expression in the Pacific Northwest. While there is much to be learned and improved on reducing our impact on the environment, many of the strategies have been a part of our work for years. HKP actively incorporates sustainable design principles in all of our work and we attempt to help clients understand the long-term benefits both to our environment and to their operation and maintenance costs. Many projects are on track for LEED (click on “LEED” for more information) certification or have been designed using the LEED rating system as a goal and guide. In 2006 the State of Washington Office of the Superintendent of Public Instruction released the Washington Sustainable Schools Protocol (WSSP) as a means for local school districts to implement state requirements for High Performance Public Buildings.
