REDUCE HEAT GAIN from outside the building by use of the site and its microclimate. The first issue to resolve is the relationship between human physiology and climatic conditions.

BUILDING FORM & FABRIC – domestic scale buildings Materials – non-determinant due to little variation in temperature lightweight preferred for quick responsePlan shape – thin plan to maximize cross ventilation & allow high levels of natural light; avoid dark areas as this encourages growth of moldSection – open section to maximize stack ventilationPlan orientation – windows facing prevailing breezes for ventilation smallest building aspect to east and west to reduce solar heat gainLandscape – use tree canopy to shade building but allow breezes plantings dissipate heat and glareVerandas – rain and sun protection for walls provide diffused lightCourtyards – light and ventilation to deep plan buildings diffused light and glare reductionRoof - light color to reflect solar radiation parasol type to maximize ventilation reflecting foil under roof to reflect radiation minimize area of roof lightsWalls - avoid windows to the east and west reflecting foil laminate in walls to reflect radiationFloor – light colored to reflect solar radiation lightweight elevated

VENTILATION - the primary element of passive cooling. SHADING - building context a major factor in passive cooling.

STRUCTURAL SYSTEM:

The structural system of CMU blocks, steel beams, and structural pre-fabricated concrete panels is chosen for ease of construction and suitability to the climatic conditions: high heat/humidity, extremely strong winds, frequent rain, and possibility of earthquakes. The deep overhang of the roofs, which could become an air foil when subjected to Guam’s maximum winds of 170 mph, will be held in place by the weight of the metal roof and a special anchoring system.

Vaulted ceilings feature clerestory windows and typhoon louver vents, situated on the dorsal side of a ventilation box that runs beneath the assembly. The design allows the house to accept storm winds as well as the prevailing breezes without rain infiltration.

Pre-cut steel members allow for accelerated assembly of roof and deck elements. ‘Top down’ construction provides shelter from the sun and rain for construction crews and building materials.
