Lecture 2: Local Climate And Solar Architecture Tropical Design for Architecture – Philippines
- LOCAL CLIMATES are climates of comparatively small regions having fairly uniform / similar natural conditions.
- It is characterized by statistical conclusions drawn from long-term observations made by meteorological stations in the region.
- Determined by the nature of the ground surface in the given region—the topography, soil, vegetation, urban buildings.
- These features are significant in the lower layer of the atmosphere. They gradually level out with increasing altitude.
TROPICAL DESIGN RESPONSES TO SUN AND LOCAL CLIMATE (TROPICAL)
- TOPOGRAPHY – the arrangement of the natural and artificial physical features of an area.
- ORIENTATION – position of a building with respect to the sun
- TRELLISES, PERGOLAS & COVERED WALKWAYS
- OVERHANGS – Overhangs are horizontal protruding elements, usually of the roof which may provide protection for lower levels.
- SUNSHADING – Sunshade are external vertical structures, acting like a skin, that reduce the amount of radiation penetrating the building.
Bris Soleil – sun-shading structures
Exterior Sunshading Systems:
Horizontal Vertical Louvers
Kinds of Interior Sunshading Systems:
- Window Blinds
- Glass Tinting
- Block Panels
- THERMAL MASS – principle that describes how the mass of the building provides “inertia” against temperature fluctuations.
