d e fi n ea climate responsive
architecture where the buildings are specifically
designed to achieve thermal comfort at the
tropical region.
High humidity and
temperature
High annual precipitation
High solar radiation

Thermal Effects of Material
design strategies
Sun shading devices
Building orientation
Maximum ventilation
Choice of material
sun shading devices
* reduce amount of radiation *by reflection and absorption
* improve distribution of light *
types of shading
• retractableshutters, roller blinds, louvers
• fixed redistribution deviceoverhangs, reveals, fins, light shelves
types of shading
• fixed reduced transmission devices perforated sheets, tinted, reflective, fritted glass, brise soleil, trees
types of shading
bui ld ing or ientat ion
• minimize solar gain,maximize natural ventilation
• avoid facing east & westmaximum sun exposure
• main windows & longer sides face
north or south to catch
prevailing breeze
venti lat ion• to better indoor air quality
& achieve thermal comfort• natural & mechanical• two principles:–Cross ventilation–Stack ventilation
examples of strategies
• elongated floor plan• minimum internal partition• elevate house on stilts
to optimize natural ventilation
• high ceilings (to diffuse interior heat)• high level window/clerestory• vents in the roof
examples of strategiesto optimize natural ventilation
• windows on opposite side• maximize window openings (size and
distribution)• some shading methods: louvers,
trees
examples of strategiesto optimize natural ventilation
Design Strategies in a Traditional Malay House
choice of material
• thermal mass of material– lightweight material:
timber, wood, galvanised iron
• durability– concrete, brick
• good insulator of heat– thatch, terra cotta, build
double walls, etc
