Aconcise "how-to" document was producedto enable
designers to implement key window and lig hting inte-
gration design concepts. The eleven-section document
was designed with rules-of-thumb and short calcula-
tionstoquickly determine if daylighting is aviable strat-
egy,with additionalpointers to more detailedtools and
resources.

The tool targets the work style of the majority of archi-
tects who conduct business within the context of tight
fees, insufficientresources,andmultiple design consid-
erations. More importantly,it reminds designers of the
far-reaching effects of merely specifying the style of a
window--from the capacity of the mechanical system
and comfort of the occupantsto its impacton the envi-
ronment.Since the design of windows with daylight
involves knowinghowtobalancesolarheat gains
against the admission of useful light, this tool informs
designers of this complex balance point and enables
them to assess design trade-offs sensibly within these
energy-efficiency boundaries (e.g., larger glazing area
with acceptable comfort is possible with spectrally se-
lectiveglass). Thedocumentcanbe read or downloaded
fromthe World Wide Web and has also been distrib-
uted toparticipating utilities, universities, and interna-
tional research institutions.
