The skylight system was developed using outdoor physical model tests and simulation tools Limited on-site measurements and occupant polls were conducted. Market issues were addressed. The skylight systems were found to improve lighting quality and to control excessive daylight illuminance levels compared to a conventional diffusing bubble skylight. Daylighting principles developed in earlier work for vertical glazing systems (light shelves and light pipes) were shown to be applicable in skylight designs at full-scale.</p>1 aLee, Eleanor, S.1 aBeltran, Liliana, O.1 aSelkowitz, Stephen, E.  uhttps://facades.lbl.gov/publications/demonstration-light-redirecting
