Which item is not covered in a renewable energy feasibility study according to RE-6?

The purchase of Renewable Energy Certificates (RECs) is not typically considered a direct aspect of a renewable energy feasibility study as outlined in RE-6 of the Estidama Pearl Building Rating System. A feasibility study focuses on evaluating the potential for implementing renewable energy systems on a site, which includes assessing factors such as site assessment, design of renewable energy systems, and cost analysis.

Site assessment involves evaluating the location’s solar, wind, or other renewable energy potentials, which are essential for determining the feasibility of generating renewable energy. The design of renewable systems pertains to how these systems will be structured and integrated into the building or site. Cost analysis is critical because it helps to understand the financial viability of such systems, including potential savings and investment returns.

However, the purchase of RECs is more of a financial transaction performed after decisions about renewable energy usage have been made. While RECs could play a role in a broader context concerning renewable energy goals and compliance, they do not fall within the primary scope of evaluating the immediate feasibility of the renewable energy systems being considered for a specific project. Thus, the correct answer highlights the focus of a feasibility study on operational aspects rather than financial transactions related to renewable energy credits.
