addition non consideration of physical environment for material application has results
dampness and condensation on exterior and internal surfaces of buildings. This
moisture movement implicated in numerous ways i.e. starting from peeling of paint to
decay of plaster surface.
v. It has been frequently observed that housing have not been provided with essential
ventilation required for kitchens and other wet areas of the house. Absence of
ventilation ducts in housing with only fan ventilation or nominal ventilation can create
moist and stale environments, which have been associated with numerous adverse
physical health conditions, including respiratory disease, aches and pains, allergies,
asthma, headaches and fever (Howden-Chapman, 2004; Matte & Jacobs, 2000). The
ventilation factor is vital for hot and humid physical condition of Karachi city and
ranking of this factor marked buy users is evident that housing is not properly designed
in terms of ventilation.
vi. Narrow staircase and passages, etc. where the housing stock includes narrow stairs,
narrow doorways, inaccessible toilets and bathrooms, or rooms too small or hot to be
used, people whose mobility is diminished by illness, accident or people will find
themselves disabled by their homes (Heywood, 2004). The ignorance of this factor is
also evident through ranking marked by users at various housing stocks. This factor is
also consistent with ventilation. Therefore, almost same equal ranking has been
marked by users for both factors.
vii. Improper joints between finished faces are correlated with factor of improper material
selection. Users have identified the presence of both factors in their respective housing
and marked this factor within fair implication range. The implication results in the
form of rain penetration, loss of adhesion, diagonal cracking at vertex, etc.
The user‘s sensitivity index as shown in Table 5 results from higher value of mean marked for
each factor of architectural design faults, mentioned in the questionnaire. The resultant
sensitivity index assimilated from the user's response it reveals that most of the faults occur
through the effects of external factors and agencies on building materials. In a broader
spectrum, these factors and agencies can be integrated in four principal components such as.
i. Lack of knowledge about materials properties.
ii. Deficient design of wet areas
iii. Poor workmanship.
iv. Non awareness of regional physical conditions
