Which of the following is required to earn Energy and Atmosphere Credit, Renewable Energy Production if using a Solar Photovoltaic System?
Answer(s): D
The Energy and Atmosphere Credit, Renewable Energy Production rewards projects that use renewable energy systems to offset building energy costs. According to the LEED Reference Guide for Building Design and Construction, the credit has two options: Option 1. On-Site Renewable Energy and Option 2. Off-Site Renewable Energy. Option 1 requires the project to use renewable energy systems that are located on the project site and that produce electricity or thermal energy for the project. The amount of renewable energy production is calculated based on the percentage of the annual energy cost that is offset by the renewable energy systems. Option 2 requires the project to use renewable energy systems that are located off the project site and that are owned by the project or have a long-term contract with the project. The amount of renewable energy production is calculated based on the percentage of the annual energy use that is offset by the renewable energy systems.Therefore, among the given options, only Option D is relevant to the credit requirements, as it implies that the solar photovoltaic system is located on the project site and that the produced electricity is consumed by the project. The other options, such as carbon offsets, daylighting strategies, and passive solar strategies, are not directly related to the credit requirements, although they may have other benefits for the project.

An HVAC system consists of an air handler supplying conditioned air (mixture of return air and outdoor air) to an office, corridor, conference room and lobby. For Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance, the ventilation rate procedure calculations must be based upon what HVAC system configuration?
Answer(s): B
A multiple-zone system is a system that has one or more air handlers supplying conditioned air to more than one zone. A zone is a space or group of spaces within a building with heating and cooling requirements that are sufficiently similar so that desired conditions (e.g., temperature) can be maintained throughout using a single controlling device. The ventilation rate procedure calculations must be based on the multiple-zone system configuration because the HVAC system in the question serves different zones with different ventilation requirements.

Which rating system is being used if all of the credits below have been submitted towards certification?- Location and Transportation Credit, Reduced Parking Footprint- Energy and Atmosphere Credit, Fundamental Refrigerant Management- Indoor Environmental Quality Credit, Acoustic Performance- Materials and Resources Credit, Persistent, Bio accumulative, and Toxic (PBT) Source Reduction - Lead, Cadmium, and Copper
Answer(s): C
The rating system that is being used if all of the credits below have been submitted towards certification is Building Design and Construction: Hospitality. This is because the Location and Transportation Credit, Reduced Parking Footprint and the Indoor Environmental Quality Credit, Acoustic Performance are only available for the Hospitality rating system among the four options.The other two credits are common for all the rating systems.

A project's total site area is 240,000 ft2 (22 297 m2) and the building footprint is 40,000 ft2 (3 716 m2). How much outdoor space and vegetated space must it provide to earn Sustainable Sites Credit, Open Space?
According to the LEED v4 Reference Guide for Building Design and Construction, the project must provide outdoor space that is at least 30% of the total site area (including the building footprint), of which at least 25% must be vegetated. In this case, the project must provide 0.3 x 240,000 ft2 = 72,000 ft2 (6 689 m2) of outdoor space, of which 0.25 x 72,000 ft2 = 18,000 ft2 (1 672 m2) must be vegetated. Therefore, option C is the correct answer.

Which of the following will result in a higher demand for potable water use in irrigation?
The answer is C. A high evapotranspiration rate will result in a higher demand for potable water use in irrigation. Evapotranspiration is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants. The higher the evapotranspiration rate, the more water is lost from the soil and plants, and the more irrigation is needed to replenish the moisture. The other options will not increase the demand for potable water use in irrigation. A sparsely planted area will have less vegetation and less transpiration, reducing the water demand. A drip irrigation system will deliver water directly to the plant roots, minimizing evaporation and runoff, and saving water. A rainwater harvesting system will collect and store rainwater for irrigation, reducing the reliance on potable water sources. For more information on outdoor water use reduction and irrigation efficiency, you can refer to the LEED v4 Reference Guide for Building Design and Construction or the WaterSense Water Budget Tool.
