Climate change resiliency


CLIMATE change resiliency is one of the major categories in building assessment conducted by the Philippine Green Building Initiative. One of its major categories is soundness of structure, which means that buildings must be structurally capable to withstand various stresses, based on established seismic, floodwater flows and wind pressure thresholds.

CLIMATE CHANGE is everyone’s favorite punching bag. Many are quick to put the blame on climate change for just about anything that’s going wrong.   Some people in government admit that it is difficult, if not impossible, to solve the many environmental problems plaguing our country due to the complex nature of climate change.

Many experts are now in agreement that climate change resiliency is what we need.

Greenhouse gas emissions arising from human activities in the last 200 years have altered the atmosphere and continue to do so at an alarming rate. Significant disturbances to the natural cycles have been created by humans. Three-fourths of such disturbances are said to be caused by fossil fuel burning and one-fourth by deforestation and land-use change.

The effects of climate change are felt especially in coastal cities where sea level rise and frequent storm surges can be catastrophic.

We are well-advised to learn to understand the natural laws of our living systems in order for us to work with nature and not against it. Our climate mitigation systems must be in sync with our local climate.

Urgently needed

Climate change resiliency in the built environment is needed urgently for buildings to have the capacity to absorb disturbances, the ability to function so as to retain the same essential function, structure and identity.

Climate change resiliency is one of the major categories in building assessment conducted by the Philippine Green Building Initiative, a building rating body composed of the building professional organizations of architects and engineers.

Its rating tool is called GrEEEn for Geared for Resiliency and Energy Efficiency for the Environment. Buildings that include the following strategies can earn points to achieve PGBI Certification as a truly green building.

Passive systems

In times of power black-out caused by natural disaster, building structures should be able to provide ample support for productivity and comfort through passively designed or nonmechanical lighting and ventilation systems.

Natural light and air harvesting systems include light shelves, skylights, clerestories, insulated windows, overhangs, screens and baffles. Operable windows are a must in our weather. Insulated and reflective building envelope components reduce heat gain. Floor surface area receiving natural daylight and wind flow must be computed during the design phase.

Designing for flexibility in mind includes an open layout which reduces construction cost, improves daylight and natural ventilation, reduces duct runs and eases reconfiguration of space.

Buildings must be structurally capable to withstand various stresses, based on established seismic, floodwater flows and wind pressure thresholds. Updated National Building Codes include structural parameters, setbacks from waterways, bodies of water, radius of safety from active volcanoes and prescribed setback from fault lines.

Overhead water tanks can supply key areas through gravity feed. Collected stormwater or recycled water will minimize use of potable water.

Buildings shall be equipped to be self-sustaining for power (through power generator or renewable sources) and potable water for a maximum of seven days.

Occupants should have minimal difficulty to exit from the building. Design should provide for more than standards stipulated by the local disaster and coordinating council with local disasters in mind for egress and evacuation.

    Climate Blame and Reefer Madness share the same page in the history books now. Nice job girls.
    We owe it to our children to be authentic and intelligent progressives again who doubt, challenge and question all authority in order to legitimize that authority, especially an authority that condemns our own children to the greenhouse gas ovens of climate change. So explain how the world of science would all get together and lie we ask? Because they only agree it is happening, not that it is a real crisis. Not one IPCC report isn’t qualified with “could be” etc. The scientists didn’t lie, we exaggerated and now former believers make better planet lovers.
    *In all of the debates so far, Obama hasn’t planned to mention climate change once.
    *Obama has not mentioned the crisis in the last two State of the Unions addresses nor any of the debates.
    *Occupywallstreet does not even mention CO2 in its list of demands because of the bank-funded carbon trading stock markets run by corporations.
    *Julian Assange is of course a climate change denier.
    *Canada killed Y2Kyoto with a freely elected climate change denying prime minister and nobody cared, especially the millions of scientists warning us of unstoppable warming (a comet hit).
    We need to stop loving the planet with fear and demand that the millions in the global scientific community finally say in one voice that it will or will not happen, not might happen. Only a comet hit could be worse and let’s save the little tiny catastrophic climate crisis for Harry Potter movies.
