Daylight quality and quantity in
Algeria schools shows an urgent condition to ensure visual comfort for students
and teachers. Some problems arise due
to poor window design and excessive amounts of daylight penetration inside the
classrooms as well as non-uniform daylight, which may cause glare and heat gain. This study aimed at choosing
an ideal window size and glazing pattern to maximize daylight effectiveness and
occupant comfort in Algerian schools. Field measurements of selected
classroom were carried out in selected school in Algeria during summer and
winter season. The data were analysed and used to develop model design for
simulation. Seven patterns of glazing
windows design were used for extensive simulation exercise. The results of the
investigation from the site measurements show that WWR was more than 40%; the
WPI was found to be within the range of 300lux to 500lux and the DF of 4%,
which exceed reference value except the southeast orientation 2.98% in morning
and 2.29% in the evening. Result from simulation using IES by
comparing three different glazing types (tint, clear and reflective) and using
different glazing size from 25% to 75% in
winter season (under overcast sky condition) and summer season (under
intermediate sky condition). The
evidence from this study suggests that tinted windows in both winter and summer
is ideal as the simulations result shows that significant usable area of
(31.22% - 41.74%) is achievable in a bilateral window opening with a (DF<2 25="" 300lux="" 30="" 500lux.="" 50="" 75="" a="" adequate="" algeria="" and="" as="" be="" bilateral="" by="" configurations="" daylight="" daylighting.="" design="" different="" during="" enhancement="" experiment="" for="" from="" further="" glass="" glazing="" has="" ideal="" impact="" improve="" in="" increasing="" it="" louvers="" need="" of="" overhangs.="" percentage="" public="" quality="" quantity="" range="" research="" result="" school="" schools="" shelves="" significant="" span="" steaming="" suggest="" that="" the="" tinted="" to="" unobtainable="" use="" variations="" vt="" was="" with="" within="" would="" wpi="" wwr="" yield="">
