Green Building Rating Programs

Green building rating programs have played a major role in encouraging green construction around the world. By identifying environmentally friendly standards for various building types and phases of development, they serve as guides to the planning, designing, construction, operation, and maintenance of green buildings.



PhilGBC is a non-stock, non-profit organization, comprised of building and construction industry leaders from both the public and private sectors.


BERDE Certification

BERDE Green Building Rating Schemes have been developed for new construction, and for retrofits and renovations. The certification process looks into 11 categories, as follows:

Management – focuses on the applicant’s commitment to national and local laws, plus measures that exceed these laws to improve the building’s environmental performance in all of its life stages, from pre-construction to operation.

Land use and ecology – focuses on the development and condition of the site, including pollution control, protection of ecological features, and control of environmental impacts.

Water – looks into water conservation and wastewater management measures.

Energy – reviews measures for energy efficiency and reduction of energy consumption in all phases of the building’s life.

Transportation – reviews options provided to decrease transport circulation and encourage alternative transportation with a smaller carbon footprint.

Indoor environment quality – evaluates conditions that affect human comfort, including lighting, indoor temperature, acoustics, and others.

Materials – covers civil, electrical and architectural works, focusing on measures for recycling, handling of hazardous substances, and reduction of CO2 emissions.

Emissions – deals with measures to control and prevent harmful emissions.

Waste – looks into waste management and recycling measures in all of the building’s life phases.

Heritage conservation – covers measures preserving heritage buildings and structures, and promoting heritage features.

Innovation – encourages the use of innovative features and technology that will positively impact the building’s energy efficiency.
