PROPOSED WALL SECTION
The Military and Naval Science Building, located on UNL’s city campus, has been used for military training programs for over half a century. While it has undergone some renovations in the past, the interior floor plan of the building remains relatively unchanged from when the building opened in 1947. Exterior air film
The main goal of the proposal for the Military and Naval Science Building renovation is to make it as energy efficient as possible and to help lower the overall building expenses. This will be achieved by updating the heating and cooling loads for the building, as well as the pressure and temperature zones. The addition of insulation to the walls will help regulate temperature and cut down on energy costs. By replacing the existing HVAC system with a VAV system with radiation, and updating the plumbing fixtures, the building will be able to function at a higher level. The proposal also includes additional outlets in many of the offices and classrooms, showers in the men’s restroom, and an elevator to help bring the building up to ADA standard. These changes are intended to meet LEED standards, and create a more green and sustainable building that operates as efficiently as possible.
