Philippine Green Building Code

Philippine Green Building Code:

  • Referral code of the National Building Code of the Philippines

  • Approved June 22, 2015

  • Reduce GHG, gas emissions, energy and water consumption by 20%

  • Towards reduction of carbon emissions by 70% by 2030

Sustainable Development:

  • An approach to development that looks to balance different, and often competing, needs against an awareness of the environmental, social and economic limitations we face as a society

  • meets the needs of the present, without compromising the ability of future generations to meet their own needs

  • Finding better ways of doing things, both for the future and the present

PhilGBC Policies:

  • Right of the people to a balanced and healthful ecology in accord with the rhythm and harmony of nature against the the harmful effects of climate change;

  • Safeguard the environment, property, public health in the interest of the common good and general welfare consistent with the principles of sound environmental management and control; and

  • Regulate site location, planning, design, quality of materials, construction, use, occupancy, operation and maintenance.

PhilGBC Objectives:

  • Improve efficiency of building performance through a framework of acceptable set of standards

  • Set minimum standards for compliance and not intended to rate buildings.

BERDE: Building for Ecologically Responsive Design Excellence

PhilGBC Principles:

  • The technical professionals, developers, contractors, property managers and building owners involved in the planning, design, construction and management of buildings have the opportunity and responsibility to help government address the adverse effects of climate change by ensuring that buildings are planned, designed, constructed, operated and maintained to the required efficiency level.

  • Occupants of green buildings will benefit from improved indoor environmental quality, which promotes higher productivity and better comfort.

PhilGBC Concept

  • Green building is the practice of adopting measures that promote resource management efficiency and site sustainability while minimizing the negative impact of buildings on human health and the environment. This practice complements the conventional building design concerns of economy, durability, serviceability and comfort.

Green Design:

  • Energy-efficient healthy, comfortable, flexible in use and designed for long life (Foster+Partners, 1999)

  • Minimal impact on the environment, both in terms of products and materials used in the construction but in the functionality of the building

  • Minimizes harmful effects on human health and the environment

    (Cravenm 2017)

  • Improve overall building performance and minimize life-cycle environmental impact and cost (AIA)

THE HIGHEST GOAL OF GREEN ARCHITECTURE IS:

  • to be fully sustainable

GREEN PRODUCTS:

  • Products made with salvaged, recycled or agricultural waste content.

  • Products that conserve natural resources

  • Products that avoid toxic or other emissions

  • Products that save energy or water

  • Products that contribute to a safe, healthy built environment.

Green products

  • A collection of green products applied to a building design do not necessarily make it a green building.


  • Achieving higher sustainability requires a carefully orchestrated, integrated approach to:

    • design principles

    • client priorities

    • environmental considerations.


PhilGBC Approach:

  • Staggered or incremental approach and is subject to periodic review;

  • to modify or include new aspects and emerging efficient technologies and expand the coverage to other building use / occupancy or replace outmoded measures.


PhilGBC Application

  • Shall apply to all new construction and/or with alteration of buildings in the following classification with the required minimum Total Gross Floor Areas (TGFA)
