A structural engineer is the most appropriate professional to analyze the roof structure and determine its ability to support the system. Roofing contractors specialize in installing and repairing roofs, but they may not have the expertise to assess the structural integrity of the roof. Mechanical engineers focus on designing and analyzing mechanical systems, not evaluating the structural capacity of buildings. Local code officials may have knowledge of building codes, but they may not have the specialized expertise to analyze the roof structure. Therefore, a structural engineer is the best choice for this task.

The increase in PV production can be attributed to multiple factors. Firstly, the lowering of the price of silicon, which is a key material used in PV panels, has made the production of PV panels more affordable. Secondly, advancements in manufacturing techniques have led to increased efficiency in the production process, resulting in higher output. Lastly, improvements in the performance and return on investment (ROI) of PV systems have made them more attractive to consumers and investors, leading to an overall increase in PV production.

All of the options listed - securing a bank loan, obtaining a line of credit, and leasing the system through programs like a Power Purchase Agreement (PPA) - are viable ways to fund a renewable energy system. Securing a bank loan involves borrowing money from a bank specifically for the purpose of financing the system. Obtaining a line of credit allows for flexible borrowing and repayment options. Leasing the system through a PPA involves entering into an agreement where a third-party owns and operates the system, and the customer agrees to purchase the energy generated by the system. Therefore, all of these options can be used to fund a renewable energy system.

The correct answer is Peterson Field House at the University of Mount Union. This means that out of the given options, Peterson Field House at the University of Mount Union has the largest single solar array thin-film laminate system in Ohio.

The production of PV has nearly doubled every two years since 2002. This means that the amount of PV produced has been increasing at a rapid rate, with each year's production being approximately double the previous year's production. This exponential growth pattern has led to a significant increase in the overall production of PV over the years.

Above-sheathing ventilation is a natural convective cooling technique that involves creating a gap between the roof sheathing and the insulation layer. This allows for the movement of air, which helps to remove heat from the roof and reduce the temperature inside the building. By promoting airflow, above-sheathing ventilation helps to prevent the buildup of heat and improve the overall energy efficiency of the building.

The advantage of using a standing seam metal roof under a PV system is that it can be installed to a pitch that maximizes the sun's angle, metal can provide a substrate or roof covering that has a life span equal to or greater than the PV, and standing seam metal roofing allows PV to be installed without penetrating the roof surface.

The MasterFormat number for Photovoltaic Collectors is 26 31 00. This number represents the specific category or classification for Photovoltaic Collectors within the MasterFormat system. Each number in the MasterFormat system corresponds to a specific division, section, or subsection of construction information. In this case, 26 represents the Electrical division, 31 represents the Photovoltaic Collectors section, and 00 represents the subsection for Photovoltaic Collectors.

Thin-film PV laminates weigh approximately 1 pound per square foot.

The correct answer is "Directly above the seam clip" because installing the seam clamps directly above the seam clip ensures proper attachment and stability of the crystalline PV module on the standing seam metal roof. Placing the clamps anywhere else may result in an insecure installation and potential damage to the PV module.

The correct answer is $30 to $50. This means that the cost of a PV installation per square foot falls within the range of $30 to $50, before any incentives or discounts are applied. This range indicates the typical cost range for installing a PV system, which includes the necessary equipment and installation labor.

The SRI (Solar Reflectance Index) is a unitless value that is calculated using ASTM E 1980, which is the Standard Practice for Calculating Solar Reflectance Index of Horizontal and Low-sloped Opaque Surfaces. This standard provides the guidelines and procedures for determining the SRI of different surfaces, which is an important factor in assessing the energy efficiency and heat island mitigation potential of buildings and materials.

The solar units at the New Jersey Meadowlands Commission's Center for Environmental and Scientific Education are expected to produce a peak maximum of 33,000 watts of electricity. This indicates that the solar units have a high capacity to generate electricity, which is important for meeting the energy needs of the center.

The installation of a new metal roof in a school in rural Nevada, along with the use of non-penetrating clamps to attach the solar modules, resulted in a reduction of labor time by 25%. This means that the installation process was made more efficient and required less time and effort.

Having a metal roof that meets or exceeds the 25-year life of most solar panels provides tremendous financial savings. This means that if the metal roof lasts for 25 years or more, it will align with the lifespan of the solar panels. This is important because it ensures that the roof will not need to be replaced before the solar panels, saving the homeowner from incurring additional costs. Additionally, a longer-lasting roof also means that the homeowner can maximize the financial benefits of the solar panels over their lifespan.

LEED SS Credit 7.2: Heat Island Effect - Roofs encourages the use of roofing materials compliant with SRI (solar reflective index) values. The SRI is a measure of a material's ability to reflect solar heat, with higher values indicating better heat reflection. By using roofing materials with higher SRI values, buildings can reduce the heat island effect, which refers to the phenomenon of increased temperatures in urban areas due to the absorption and re-emission of solar radiation by buildings and paved surfaces.

Before considering any type of PV system, it is wise for a building owner to reduce the building's energy consumption as much as possible. This is important because reducing energy consumption can help optimize the efficiency and effectiveness of the PV system. By reducing energy consumption, the building owner can ensure that the PV system is not being used to offset unnecessary energy usage, resulting in a more cost-effective and sustainable solution. Additionally, reducing energy consumption can also help determine the appropriate size and type of PV system needed for the building's energy needs.

The question is asking for the minimum Solar Reflectance Index (SRI) required for a low-slope roof to qualify for the SS Credit 7.2: Heat Island Effect - Roofs. The correct answer is 78, which means that the SRI must be greater than or equal to 78 for the roof to meet the qualification criteria. The SRI measures the ability of a surface to reflect solar heat, with higher values indicating greater reflectivity and lower heat absorption. Therefore, a higher SRI is required to qualify for the credit and contribute to reducing the heat island effect.

To qualify for the SS Credit 7.2: Heat Island Effect - Roofs, a steep-slope roof must have a Solar Reflectance Index (SRI) that is greater than or equal to 29. The SRI is a measure of a roof's ability to reflect solar heat, with higher values indicating greater reflectivity. Therefore, a minimum SRI of 29 ensures that the roof has a sufficient level of reflectivity to mitigate the heat island effect, which is the phenomenon where urban areas experience higher temperatures due to the absorption and retention of solar heat by buildings and pavement.

Crystalline PV modules weigh approximately 3 pounds per square foot.

Using rooftop PV systems will allow a building to generate renewable energy on-site, which aligns with the criteria for earning points in EA Credit 2: On-Site Renewable Energy. This credit focuses on promoting the use of renewable energy sources to reduce the building's reliance on non-renewable energy and decrease greenhouse gas emissions. By installing rooftop PV systems, the building can generate clean energy from the sun, thereby contributing to the achievement of LEED certification.

It is recommended to have two annual inspections for an installed PV system. These inspections are important to ensure the system is functioning properly and to identify any potential issues or maintenance needs. Regular inspections help to maximize the efficiency and lifespan of the PV system, as well as ensure the safety of the system and its surroundings. By conducting two annual inspections, any necessary repairs or adjustments can be made promptly, reducing the risk of system failures or inefficiencies.
