WebJul 5, 2024 · [9.4.7] The ratio of the luminous flux (lumens) received on the work plane to that emitted by the luminaire. Note: This ratio sometimes is called interflectance. Room utilization factor is based on the flux emitted by a complete luminaire, whereas coefficient of utilization, CU , is based on the total flux generated by the lamps in a luminaire. WebThe heat utilization factor is the ratio between the difference between the ground temperature and the ... The dryer performance in terms of heat utilization factor (HUF), coefficient of ...
WebThe coefficient of utilization (CU) is a measure of the percentage of lumens incident on the workplane to the total emitted lumens from the lamps in the luminaire. The CU value takes into account the room geometry, surface reflectance, and efficiency and distribution of the luminaire. The CU table computed by Photometric Toolbox is applicable ... WebJun 24, 2024 · The simultaneity factor is also widely used by architects, engineers, developers and electricians. They use it to calculate the electrification of a building and the electricity report (EIC) for each home, premises and garage. There are three power scores: high, medium and low.
WebGuttman split-half reliability was used to measure equivalence for the CV-GMDS. A coefficient of 0.80 or higher shows adequate reliability and 0.90 or higher shows good reliability in a common rule of thumb. To examine the conceptual structure of the CV-GMDS, we applied a factor-analytic procedure with a two-factor structure.
