Download as PPT, PDF35 likes28,671 views
The document details the design and objectives for the National Renewable Energy Lab's Research Support Facilities, emphasizing a mission for a net zero energy building that achieves LEED Platinum and incorporates various energy-efficient technologies. It outlines the collaborative efforts of a multidisciplinary design-build team and innovative strategies such as natural ventilation, daylighting, and photovoltaic systems. The project aims for national recognition and serves as a replicable model for future zero-energy commercial buildings while focusing on architectural integrity and future staff needs.
