Abstract
House or residence is considered as one of humans’ basic needs. Based on a site survey in the
National Housing Authority community, Pathum Thani Province, it was discovered that this community was
built for over 40 years. The internal area of residences therefore, does not meet the usage pattern of actual
residents. It has also caused issues of lighting, insufficient ventilation, and congestion. This study aimed
to Investigate the interior physical environment of residences, residents’ usage behaviors and their opinions
on perception of congestion and stress.
This study was the research on post occupancy evaluation. The data were collected by observing
the physical environment of residences in one of the National Housing Authority communities in Pathum
Thani Province, residents’ behaviors inside 3 houses, interview with 3 informants and distributing
questionnaires to 131 residents in the community. Quantitative data were analyzed by descriptive statistic
with frequencies, percentages, means, standard deviations and correlations. Qualitative data were analyzed
by content analysis, data grouping and prioritizing.
The results showed that in terms of space, each room inside the house should be properly divided
in accordance with usage. The position of bathroom should be at the back of the house for good ventilation
and privacy. Storage should be prepared and positioned at the back area or mezzanine. For lighting, light
bulbs needed to be added inside the house considering the level of luminosity which responds to
standards, including skylights. For ventilation, the characteristics of exterior and interior openings should
have been designed together. For perception of crowding, it was found that the level of satisfaction on
space, position of usage, lighting and ventilation had significantly negative correlation against perception of
crowding. Perception of crowding had significantly positive correlation with perception of stress. The more
residents felt their houses were crowded, the more they felt stressed. Thus, to design residences in the
future, such factors need to be considered as well.
