TROPICAL DEISGN

Module 00: Introduction to Tropical Design 1 JGPL2014

TROPICAL DESIGN This is concerned with countries where discomfort due to heat and humidity are the dominant problems.

Many confuse the term tropical architecture with a particular design style. It is all about achieving thermal comfort through passive design elements:

o Sunshades o Cavity walls o Overhangs o Roof and wall insulation o Shading from large trees to block the sun

Passive design is the process of achieving comfort level without the use of mechanical systems.

TROPICAL DESIGN =

PASSIVE COOLING

Tropical architecture is all about tackling urban heat island effect. Heat island effect is a phenomenon is what results from cities that have very little

greenery and very many concrete surfaces. The city will have 2 to 3 degrees Celsius higher temperature than that of the surrounding suburbs and countryside.

Climate Responsive Architecture is a must in Building Design.

Responsive architecture using nature as an example The building exterior elements could be responsive to the wind, sun, rain, temperature,

etc. (macro). The Interior could interact digitally with the users (micro). A climate responsive building envelope is only one functional criterion for correct design.

Architects must realize that the building skin is not just specifying materials and creating a faade for aesthetics.

Building envelope design varies greatly by geographic area. When designing building envelope, factors such as insulation, vapor barriers and air

barriers will vary radically depending on the climate of the given geographical area (polar, tropical, temperate, arid).

The building envelope serves as a climatic mesh that filters the outside environment to create a proper and hopefully a comfortable indoor environment.

Proper fenestrations and building materials should be selected.

In the Philippines, hot humid conditions require protection from heat and maximum ventilation for interiors, therefore, local designs should firmly consider these issues.

Opening fenestrations such as sun-shading devices should be considered by designers.

Good building orientation must also be looked at by architects to minimize direct solar radiation but maximize potential for natural ventilation.

TROPICAL DESIGN

= Minimize SUN

+ Maximize WIND
