SMX Convention Center • Seashell Drive, Mall of Asia Complex, Pasay City, Philippines • 23-26 April 2009 Development of a Green Building Rating System for the Philippines The world is transforming into a global economy. Presently, the building and construction sector is accelerating at a very rapid pace. The adverse impacts of increased building activity are remarkable in our land, in the air we breathe, on human health, our heritage and overall quality of life. Globally, the United Nations Environment Programme (UNEP) estimates that the built environment is responsible for 25-40% of energy use; 30-40% of the solid waste generation, and 30-40% of green house gas (GHG) emissions worldwide. In the Philippines, there is an alarming increase in the environmental impact that built environment creates. The solid waste problem is mounting in the metropolis; an energy crisis is expected in the next few years, and our water resources are fast depleting. There is an estimated 8,000 tons per day of solid waste generated in Metro Manila alone. The Department of Energy targets to increase the Philippines’ current oil and gas reserves from the year 2004 level of 69.5 million metric tons of oil equivalent (MMTOE) to 83.6 MTOE by 2014 due to increased energy demand. Water borne diseases account to about 30% of all reported diseases from 19962000, largely due to improper wastewater management and with only 6 out of 115 Philippine cities having sewerage systems. These figures reflect the current stress in the Philippine environment that needs to be directly addressed. These negative occurrences are largely due to the tremendous growth presently experienced by the economy and the rapidly increasing construction activity due to increased population in the city centers. The property sector’s expansion is fueled by the demand for new and premium office space required by the business process outsourcing (BPO) and by the increased dollar remittances of Overseas Filipino Workers (OFW) that stimulated the accelerated development of more residential condominiums. 108 Green Building Green Building is the practice of designing, constructing, operating, or reusing buildings in an ecological and resource efficient manner. It focuses on the promotion and practice of sustainable site development, improvement of indoor air quality, efficient energy, water management, utilization of green materials and the preservation of cultural heritage. When buildings use less energy it reduces the demand for government to build more power plants. Improved quality of effluents from buildings helps the government maintain cleaner water resources. Improved resource management practices enables businesses t o r e d u c e waste generated at job sites, thus, requiring less landfills. The reduction of the negative impacts associated with building construction promotes the preservation of the natural ecology. It is a major contribution of the business industry in the protection of the environment. Sustainable building improves the productivity of businesses. Healthier workspaces promote building occupants comfort and health and boosts employees morale. As the business industry increases the uptake of sustainable building strategies, they are realizing that first costs are now very competitive. Accessibility to greener building materials, technology and information are accelerating the acceptance of sustainable building. With a mature market ready to embrace sustainable building, businesses will be reaping the marketing benefits that are provided by sustainable building. This enables businesses to maintain competitiveness and improve their bottom-line. Green Building Rating Tools Implemented Around the World Presently, there is an increased uptake in green building practices around the world. Several countries have established rating systems that are used as a benchmark in evaluating the level of sustainability of buildings. They provide identifying
