This multi-year project provided a mechanism for inves-
tigatingadvanceddaylightingtechnologies,strategies,
commercial prototypes,anddemonstrationsincollabo-
rationwithdesigners,manufacturers,owners,andre-
searchers.

Guidance wasprovidedto industry to ensure thattheir
market perspective was sufficiently broad--we found that

provided detailed analyses of product performance; e.g.,
holographic glazings, advanced skylights, angular-selec-
tive glazings, etc.In one case, we worked with a skylight
manufacturer to developandevaluate newskylighting

ofheatgainsandlightintensity butalso improving the
flux distribution for better visual quality.Retail sales were

With designers,we dispensedquick assistance on dem-

compass integration issues.For example, we contributed
totheconceptualdesignoftheSacramentoMunicipal
Utility District's New Customer Center,which was built
using abroadarray ofdaylighting strategies,including
skylights, spectrally selective glazing, light shelves, exte-
rior overhangs and fins for shading, atria, an "articulated"
building form, integrated task and ambient lighting, and
daylighting controls.
