EXPLANATORY NOTE

Article II Section 16 of the Philippine Constitution provides that the State shall protect and
advance the right of the people to a balanced and healthful ecology in accord with the rhythm and
harmony of nature.

This bill seeks to introduce “Green Building Rooftops” on all buildings throughout the
Philippines to live a well-adjusted and healthy environment to its people.

With the advent of Green Building Rooftops, the energy costs will be reduced through
absorbing heat instead of attracting it and providing natural insulation for buildings. According to
a study conducted by the National Research Council of Canada, even a six-inch extensive green
roof can reduce summer energy demands by more than 75 percent. Another important benefit of
green roofs is their ability to reduce and slow stormwater .runoff in urban environments.
Furthermore, plant leaves trap dust particles from the air, and evapotranspiration cools ambient
temperatures.

In view of the foregoing, the approval of this bill is eamestly sought.
