We strive to design buildings that use fewer natural resources and complement the environment with innovative, sustainable, and cost effective results.JAHN is constantly working to optimize our internal use of consumable materials, lower our energy usage, and educate our staff - creating consistency and compatibility between our design philosophy and the culture of the office.
