The recently completed headquarters for Nautilus and its Metro subsidiaries earned LEED Gold certification due in part to its 10 electric vehicle charging stations and solar covered parking stalls designed to generate over 385,000 kWh per year to the new building. Millie and Severson completed the project in February this year for Urbana Development. Additional sustainable features include increased ventilation, low-emitting materials and use of regional materials to reduce environmental impact.
