Remodel Bldg. 850, Naval Base Ventura County
Project Description
This design-bid-build project’s scope of work included a complete interior and exterior rehabilitation of the US Navy’s Bldg. 850, Public Work’s Department Headquarters, Naval Base Ventura County, Port Hueneme, CA. Every building system and architectural finish was either rehabilitated or remove and replaced in its entirety. The project was also one of the very first LEED Gold project’s in the USA. Building 850 serves as one of the U.S. Navy’s two “Energy Showcase” facilities to demonstrate applications of the latest concepts in energy-efficient and sustainable facility design, construction and operation. Located in Port Hueneme in Ventura County, California, the building is home to Naval Base Ventura County Public Works Department and provides Naval staff with direct exposure to and experience with green building principles.
The project included a 10,000 sq. ft remodel and a 7,000 sq. ft addition. This project served not only as a functioning green building but also as a living laboratory and educational tool for emerging sustainable designs and technologies. The building was carefully designed to take advantage of the local mild climate and make use of passive systems that have been integrated with the mechanical, electrical, and plumbing systems through an iterative design process that achieve maximum efficiency and indoor environmental quality. Renovated interior spaces included classrooms, lobby, restrooms, and office spaces. The renovated exterior spaces included patios, interpretive landscape, restored landscape, pedestrian/non-motorized vehicle paths, parking, bicycle storage/parking, and decorative gardens.
A major project goal for Building 850 was to create a high-quality work environment for the occupants. This was accomplished by integrating interior layout and functionality, aesthetics, lighting quality, thermal comfort, and indoor air quality. All work areas provided occupants with outdoor views, and nearly all visual task areas are daylit via windows, clerestories, and reflective light shelves. Thermal comfort is enhanced by an underfloor air distribution system for the new building addition. The existing building features operable windows to provide natural ventilation. Real-time monitoring and display of energy use; lighting levels; and building comfort monitoring of carbon dioxide levels, air stratification, air temperature, and relative humidity are used to ensure the indoor environmental quality is maintained.
A Construction Indoor Air Quality Plan was developed to prevent pollution sources from contaminating the existing building and ventilation system during the construction process. Flovent Software, which used Building 850 as a test case to calculate ventilation effectiveness, was used to calculate airflow, heat transfer, and indoor air quality for the project. Modeling results show the indoor environmental quality to be excellent and exceed recommended practices.
