he major renovation of a four-story, 40,000 sq. ft. building in Florida includes repaving existing parking areas along the entire length of the south and west facades of the building. The building and parking areas compose the entire site to its boundaries, not leaving any green space. The common afternoon rain showers have led the design team to select open-grid paving with vegetated cells equivalent to 50% of its surface in lieu of a lower-first-cost solution, such as black asphalt. Based on the information provided, which of the following benefits and LEED strategies might the open-grid paving strategy contribute? [choose three] a. Optimize energy performance b. Reduced site disturbance c. Heat island effect d. Water use reduction e. Water-efficient landscaping f. Stormwater management
a. Optimize energy performance c.

By reducing heat gain, energy use is optimized, as the building has less of a demand for cooling loads. The pavers allow stormwater to penetrate through to reduce runoff.)
The engineer working on a new corporate building project seeking LEED for Core & Shell certification, has proposed a cogeneration system that provides electricity, cooling, heating, hot water, and dehumidification of outside air.

To which of the following LEED credits might these strategies contribute? [choose two] Select one or more: a. Optimize energy performance b. Commissioning c. On-site renewable energy d. Green power e. Enhanced refrigerant management

The use of locally adapted planting allow further reduction because these plants are suited to the local climate and once established can be sustained with little or no ongoing irrigation.)
Understanding the refrigerant trade-off in regards to the effort to reduce global warming by the use of harmful refrigerants means that: [choose two] Select one or more: a. The trade-off is that some refrigerants have a higher ODP and a low GWP, while others have a higher GWP and lower ODP. Either way the refrigerant will have a harmful impact to the environment b. The trade-off is that natural refrigerants should be used in LEED projects instead of harmful ones. Natural refrigerants are CO2, NH3, and propane. c. The trade-off is that there is a treaty for the reduction of ozone depletion but not for global warming. The solution is to make a new international treaty the agrees that global warming is a comparable environmental threat to ozone depletion d. The trade-off is that LEED project teams have to choose between using refrigerants that deplete the ozone layer or refrigerants that contribute to global warming, but they will not be able to find a refrigerants that does not harm the environment unless they use all-mechanical ventilation. e. There is no real solution because while harmful refrigerants are a direct cause of global warming by leaking into the earth's atmosphere, less harmful refrigerants will indirectly cause global warming with the emissions created by additional generation of electricity due to less-efficient cooling properties.

Either way the refrigerant will have a harmful impact to the environment e. there is no real solution because while harmful refrigerants are a direct cause of global warming by leaking into the earth's atmosphere, less harmful refrigerants will indirectly cause global warming with the emissions created by additional generation of electricity due to less-efficient cooling properties.
