Design considerations
▪▪ Careful, individual site analysis is needed to identify
conditions that call for specific design adjustments.
▪▪ In all sub-zones, passive solar heating and cooling
are important.
▪▪ Different approaches are required for passive cooling
depending on the patterns and reliability of cool
breezes.
▪▪ To reduce heat gain, avoid inappropriate or overuse
of glazing.
▪▪ Passive solar heating is always desirable and
simply achieved where access to adequate sunlight
is available. Where solar access is not available,
consider using lightweight building frames
that respond quickly and efficiently to minimal,
carbon efficient auxiliary heating.
▪▪ Lower thermal mass requirements allow for low
embodied energy solutions.
▪▪ Use roof spaces as a thermal buffer zone by
ventilating them in summer and sealing them
in winter.
