CLIMATE CHANGE ADAPTATION FOR YOUR BUILDINGS/ RESIDENCES. Climate change brought about by global warming through the unchecked use of fossil fuels (chiefly coal) by industrialized countries have warmed our oceans and have given rise to supertyphoons (some also say military activities have something to do with it). We are the wall that protects Southeast Asia and parts of East Asia as the PH is the first landfall of Pacific-bred supertyphoons i.e. which grow weaker after passing the PH, thereby protecting the rest of Asia. Given this reality, climate change adaptation and disaster preparedness/ resiliency for buildings should now be the norm. We could probably start this by modifying portions of architectural designs i.e. 1) use of steeper roof slopes for metal roofs (because flatter slopes are easily penetrated by the wind); 2) use of roof that is sloped at all four (4) sides; 3) use of concrete deck roofs; 4) use of very short eaves i.e the roof extension outside the exterior wall of the building or residence, usually provided for shade and aesthetics (because long eaves cause uplift which open up the roof cavity to more/ extensive wind damage); the short eaves could be paired with media aguas (shed roofs) over windows and doors; 5) gutterless roofs (as leaves and debris clog up the drains, downspouts and catch basins and the accumulated water cause the undrained roof to collapse; 6) roof cavity and ceiling cavity openings to relieve or equalize pressure inside and outside the building during strong winds; 7) less paving around the building to help retard surface water flow that contribute to flash flooding at lower elevations; 8) proper setbacks and compliance with mandated legal easements (MLEs) along waterways; 9) use of stilted or floating buildings; 10) rainwater harvesting; etc. Thanks.
