The Darlington Energy Complex (DEC) is a premiere nuclear training centre including ground-breaking innovation and leading-edge technology.
The DEC, a multi-purpose building of approximately 300,000 square feet, includes offices for 450 staff, public information centre with interactive educational displays, 160-seat auditorium, warehouse space, and technologically advanced training centre and tool testing facility that included a full-scale mock-up of the reactor core. The structure of the center consists of cast-in-place concrete foundations, structural steel framing, insulated metal wall panels and aluminum framing with high efficiency glazing. This multi-use facility required many types of acoustic treatment to architectural components to prevent sound transmission from mechanical and tool testing areas to the office space.
The DEC is a Gold LEED certified project, achieving a 73% reduction in exterior lighting power, 50% reduction in interior lighting power, including occupancy and daylight sensors, 35% indoor water saving, and a 90% increase in efficiency in the condensing boilers.
