A certification system of the U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) is a green building certification program used worldwide. Developed by the non-profit U.S. Green Building Council (USGBC), it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods, which aims to help building owners and operators be environmentally responsible and use resources efficiently. By 2015, there were over 80,000 LEED-certified buildings and over 100,000 LEEDaccredited professionals. Most LEED- certified buildings are located in major U.S. metropolises. Environmentally Critical Areas (ECA)  ECA regulations ensure protection of water quality, groundwater recharge, stream flow, slope stability, wildlife and fisheries habitat, natural stormwater storage/filter systems, human life, and property What is ECC? The Environmental Compliance Certificate Environmental Compliance Certificate or ECC refers to the document issued by the DENR-EMB that allows a proposed project to proceed to the next stage of project planning, which is the acquisition of approvals from other government agencies and LGUs, after which the project can start implementation. What is ECP?  Environmentally Critical Project (ECP) - project or program that has high potential for significant negative environmental impact as defined under Presidential Proclamation 2146 (1981). What is CNC? Certificate of Non- Coverage A CNC is the equivalent of an Environmental Compliance Certificate (ECC) for projects that are not expected to have significant impacts on the environment. These projects are considered to be not covered by the Philippine Environmental Impact Assessment System, hence the name. China’s name for the disputed islands in the West Philippine Sea Nansha Estimated typhoon wind velocities of the super typhoon that hit Eastern Visayas in 2013 – 300 KPH Coastal areas are prone to destruction due to strong typhoons because of _____ Wave surge Agency in charge of coordinating disaster relief – NDRRMC Expected magnitude of a potential earthquake in the Marikina Valley fault system – 7.2 Agency in charge of monitoring seismic activity in our country Phivolcs HVAC is an acronym for Heating, ventilating, air-conditioning Environmental protection and subdivision reform laws affecting the availability and cost of vacant land include: a.

Of those, how many have recovered. 1.55 million “Ecology” is often used more loosely in such terms in common parlance as a synonym for the word “natural environment” Refers to the non-living elements and physical components of the environment Abiotic A large community of plants and animals that occupies a distinct region. Biome INDIGENOUS PEOPLE Indigenous Cultural Communities/ Indigenous People are groups of people or homogeneous societies identified by self-ascription and ascription by others, who have continuously lived as an organized community on communally bounded and defined territory, and who have, under claims of ownership since time immemorial occupied possesed and utilized such territories, sharing common bonds become historically differentiated from the majority of Filipinos. TRANSPIRATION - the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. - plants releasing water from their leaves, which then evaporates BIOSPHERE The portion of earth that supports life. This portion extends from the bottom of the ocean to high in the atmosphere.
