| Summary: | Microclimate studies are commonly required for new projects especially
urban masterplanning that involves the development of a sizeable area
within a city. Basically data from microclimate studies gathered from semioutdoor
spaces i.e. on airflow, sunlight, lighting and irradiation are typically
gathered through field measurements and environment simulation tools are
used to enhance the understanding of comfort issues in urban
environments in order to assist in design decision making. Simulation and
field studies generally generate large amounts of data i.e. numerical and
graphical. The aim is towards organising such data such that impact on
users as they move through space is presented the sequence in order to
increase understanding of comfort and perception from a pedestrian
viewpoint. In this paper, virtual reality (VR) used to integrate environmental
data gathered from an environmental study of selected areas in the
Putrajaya central boulevard to be presented in sequence and link to
sensations arising from the variations in the external environment. The
focus is on urban design issues related to human comfort and experience
of urban spaces, particularly in the context of hot, humid climates. In this
climate, the shading issues, heat gain and radiation are a critical issue that has to be assessed through simulation and field work. However V. R can be
useful to analyse such open areas or areas between buildings whose
microclimate are considerably affected by the insertion of the building
mass in the urban fabric. The synchronized-data can be displayed as
"gauges" in animated sequence or real time. As the 'user' walks through
the spaces in the VR, the line graphs on the gauges will change to indicate
the variations in the environmental parameters such as light, air speed and
temperature experienced in urban microclimates. |
