Candela Candela The candela ( or ; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly
Rosario Candela the apartment buildings. Candela's greatest work would occur during the latter half of the 1920s, when he designed numerous apartment buildings on the Upper East Side, primarily on Fifth Avenue and Park Avenue, as well as at Sutton Place and other locations. In 1927 and 1928, Candela designed 19 apartment buildings, including 960 Fifth Avenue (at East 77th Street) and 720 Park Avenue (at East 70th Street). He had more commissions in 1929, but the housing boom had begun to slow prior to the stock market crash in October. Of 27 designs that year, only 12 were completed. These included
