WIND TOWERWind Tower works in system of air intake and outake by differencein air pressure and temperature. The former is acheived when openingis either facing wind direction or opposing it to create intake andsuction respectively. Multidirectional wind shaft help system functionunder varies wind direction. Heating of the chimney enhance day exhaustand night air exchange to outside. Wind Tower could work withhumidifier to cool air through evaporative coolingARCH 3424 l BUILDING TECHNOLOGY III l Gary, Yeung Ho Yin l 1155011552VENTILATIONIn the middle is a internalcourt to provide largeopening to intake modified mildair and work with exterior smallopening to cross ventilate.COMPACT SETTLEMENTSettlement should be groupedtogether in a compact form tominimize heat gain or excessiveheat loss in relation toexposed surface .areaTHERMAL MASSHeavily constructed are used the sand wall,which is thicker then 300mm, roof is providinga largeheat bank to store up daytime heat for nighttimewarming use.LIMITED, SMALL, HIGHIn hot-dry climate, air temperaturecan go above blood temperaturewhich renders ventilation at occupantlevel undesirable. Alsosaudi arabiafrequentharzard of Sand storm.Therefore opening should be keptto the minimum and small in size.High window is preferred to onlyfulfill need of air exchange.elongated OpeningOpening are done in a wayto block out high angle sun at hotseason and admit low angle sunin cooler time.East and West opening shouldbe restrained.
