AbstractThe lack of daylighting monitoring protocols and procedures for buildings has greatly contributed to thesmall number of monitored daylit buildings. As a result, high electricity savings claims from daylightingwere mostly driven from modeling, illuminance measurements from test cells or scale modeling, or fromjust high daylighting availability. Daylighting field-measured data with respect to transient daylightingcontribution and electrical lighting control are very limited. Furthermore, well-daylit buildings do notnecessarily ensure energy savings as occupancy patterns, improper daylight-linked electrical lightingdesign, and associated thermal loads can negate high potential energy savings. For daylighting to beconsidered as a source of energy savings in buildings, monitoring the daylighting performance of real casestudies becomes an essential procedure.
