Lighting and Electrical Systems Classroom - PKI 130
The lighting and electrical systems classroom is truly an immersive learning lab used to teach architectural engineering students lighting and electrical concepts which cannot be replicated through books, or simulations.
Several Minolta T-1M illuminance meters, a Minolta CS-100 Chroma meter, a Minolta LS-100 Luminance meter, and a LightSpex handheld spectroradiometer. The laboratory is equipped with a sophisticated lamp measurement system, consisting of a six-foot integrating sphere from Labsphere, a diode array spectrometer, AC/DC power regulator and conditioner, Yokogawa power meter, and two reference ballasts. The system can be used to measure all the electrical and spectral characteristics of lamps, including spectral power distribution, lumen output, color rendering, and color temperature.
10 complete overhead lighting systems illuminate the laboratory space. Fluorescent, incandescent, and high intensity discharge systems are included and controlled by a Lutron Grafik Eye 5000 dimming system.
Unpowered building electrical distribution system components have been installed: main distribution panelboard, motor control center, step-down transformer, circuit breaker panelboards, transient voltage surge suppressors (TVSS), conductors and conduit, which are connected and grounded identically to an actual distribution system. Students can see the internal components of the system, and how lecture concepts like distribution, transformation, over-current protection, and grounding are actually implemented.
The west end of the laboratory is an office mock up area, approximately 6 m (20 ft) by 5 m (16 ft). It can be configured as a single conference room or two side-by-side offices by rearranging demountable partitions. Two dedicated electrical dimming panel boards control the electrical supply, which allows students to quantitatively evaluate the electrical performance characteristics of the lighting in the space using a current transformer connected to each panel board's feeder. Receptacles in the ceiling provide at least 24 separate circuits for the lighting in this area, all of which are fully dimmable.
