Mechanical and plumbing design for a sustainable design classroom building for students interested in architecture and engineering careers in Kearny High School. It is located within the athletic facility area at the campus of Kearny High School. The design team met with site users, teachers, and students to understand how occupants use the current facilities and survey the needs of new technology for the engineering, innovation, and design classroom.
Mechanical systems were chosen based on an extensive life cycle cost analysis that determined the most life cycle cost effective mechanical system. Mechanical systems include high efficiency rooftop packaged single zone units with modulating powered exhaust. All rooftop equipment is equipped with economizers to take advantage of the temperate climate. Building exhaust systems were added as required to serve restrooms as well as to maintain building pressurization. Careful consideration was given to the controls of each system working closely with the district to provide alarm and monitoring as requested.
Plumbing systems include complete sanitary and vent system, complete domestic cold and hot water system, complete storm drain system, natural gas system, low flow plumbing fixtures, and electric water heater.
Sustainable features are included in the title 24 which shows 46.4% excluding receptacle and process or 38% including receptacle. The mechanical system was designed with variable air volume and multiple compressors for capacity modulation. Interlocks were provided on roll up doors to limit the use of the conditioning.
