Circadian Stimulus

CS - This metric indicates how well a one-hour exposure to a light source producing a certain light level and wavelength of light stimulates the circadian system, based on its ability to suppress the hormone melatonin. It ranges from 0.1, the threshold for circadian activation, to 0.7, which represents saturation.

Demand Response Participation

Demand response participation requires changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.

fc
Emittance

The capacity of a material to emit radiant energy. The ratio of the radiant flux emitted by a physical surface to that emitted by a blackbody at the same temperature and under the same conditions. It can be expressed as 1-(long-wave infrared absorptance) for materials that are not transparent in the long-wave infrared spectrum. Emittance is a surface property; values range from 0.05 for brightly polished metals to 0.96 for flat black paint. The emittance for most materials is 0.9.
