We have better than a chart of comfort zones for different indoor wind speeds and humidities - we have an interactive tool!http://comfort.cbe.berkeley.edu/EN
What we can do with this is build up a few scenarios. Possibilities:
summer nightime, what fan speed is needed for comfort for sleeping people, is that a sensible speed?
winter early morning: is it chilly, or do we still need the fan?
Summer hot rain: extreme air temps and extreme humidity combine. what air speed do we need?
Summer rain: with lower summer temps, but higher humidity, what air speeds are we looking at?
Summer cooking: with the extra humidity and heat and activness in the kitchen, what additional comfort is needed?
Vica versa, for the above cases and humidities and sensible fan speeds (or local off shore breeze), what temp do we need to keep the living space below for it to remain comfortable?
Basically, we use these to flesh out the design envelope, and get a feel, in numbers, for how different the different cases all are.
Now this image is pretty useless for design purposes, but it's a good checklist of ideas to work down.http://terra-pacific.com/wp/wp-content/ ... 1-B-01.pdf
The aussie goverment has developed a really nice set of guides, actually.http://www.yourhome.gov.au/passive-desi ... ve-cooling
Temperate climates (Zones 5 and 6)
With good design, temperate climates require minimal heating or cooling. Good orientation, passive shading, insulation and design for cross-ventilation generally provide adequate cooling. Additional solutions from the range explained here can be used where site conditions create higher cooling loads.
Design for compact form in cooler zones, extending the east−west axis in warmer zones (see Orientation).
Prefer plans with moderate building depth — two rooms is ideal.
Design for the impacts of climate change and consider highly efficient heat pump systems to cope with increases in extreme weather events.
Use thermal mass levels appropriate to the amount of passive cooling available (cool breezes, consistent diurnal variations) and use thermal mass to delay peak cooling needs until after the peak demand period.
Choose window opening styles and position windows to ensure good cross-ventilation.
Orientate for passive solar heating and divert breezes.
Employ larger northern and southern façades.
Design for moderate openings with the majority to the north.
Use minimal west-facing glazing (unless well shaded).
Use moderate east-facing glazing and moderate south-facing glazing except where cross-ventilation paths are improved by larger openings.
Use bulk and reflective foil insulation.
Use low to medium U-value and SHGC glazing in milder areas and double glazing where ambient temperatures are higher.
Why am I focussing on this?
Becuase 1) you'll have hot summers every year, floods are far less common, so should be the secondary consideration
2) Becuase most of this defines the outline of the house - the rough shape. That, and the anti flood design, will inform the construction methods used. (i've been thinking it over and I'm really unsure strawbale is the way forward for you in this climate and with the risk of a flood entering the bales. The wall is going to rot, even based on air moisture alone. You won't get your design life achieved)
