Effects of Interior Partition Locations on Air Flow Patterns
garages, laundry rooms, mechanical chases, stairways, etc.) can be
placed on the east, west, or north exposures of the building to act as
buffer spaces to minimize east/west solar gains.
Rooms with high process heat gain (such as computer rooms)
or high latent heat gain (such as laundries) should be placed near the
building's ventilative outlets or be separately ventilated in order to
minimize heat gain to the rest of the building. They should also be
separated from other ventilated spaces by insulated walls (refer to
Rooms can also be zoned so that activities can take place in cooler
areas during warm periods and warmer areas during cool periods of the day or
season (refer to para. 3.2).
Internal Drapes and Blinds. Internal drapes and blinds are not an
effective means of solar control and should not be the building's primary
shading device. Although they block solar radiation, they absorb and re-
radiate an appreciable amount of it within the room. This is true even for
white drapes and blinds. An internal white venetian blind will reduce the
daily average solar heat gain by less than 20 percent. Only exterior shading
devices should be used as the primary solar control in all cases.
