enhancement of the site and its surrounding neighbourhood.
Investigations should include:
a detailed assessment of the climatic conditions and
topographic conditions immediate to the site;
examination of the orientation of the buildings with respect to
environmental conditions, overshadowing and views;
planning of building form in response to local environmental
conditions, such as variation of heights and distances among
buildings and breaks in and between buildings, to achieve
better natural ventilation and daylighting;
The ratio between the area of a site covered by buildings, and the open
ground area without buildings within the site, affects the resistance that
the wind encounters in the particular site and the access of sun and
daylight in the site and subsequently affects pollutant concentration. Site
layout should seek to minimise any negative aspects relating to
microclimate, solar heat gain, wind, and loss of natural daylight to the
neighbouring buildings and pubic areas, as well as the development
itself.
