A Level 2 energy audit, also known as an Energy Survey and Analysis, involves a more detailed on-site inspection and comprehensive analysis compared to a preliminary audit. It includes a thorough review of energy consumption data, facility operations, and potential energy conservation measures. This level of audit typically provides a financial analysis of recommended improvements, offering a clear path for energy efficiency investments.

Option A measures key performance parameters (e.g., power draw) while stipulating less critical parameters (e.g., operating hours) from historical data.

A power meter is a specialized device used to measure the electrical power consumption of appliances, circuits, or entire facilities. It provides readings on voltage, current, power factor, and kilowatt-hours, which are essential data points for understanding and auditing electrical energy usage. Accurate measurements from a power meter are crucial for identifying energy waste and quantifying potential savings.

A positive NPV means the discounted future savings exceed the initial investment, indicating the project adds financial value.

China has made substantial investments in renewable energy infrastructure and has the largest installed capacity for wind power globally. Its vast land area, favorable wind resources, and strong government support have enabled it to become the leading producer of wind energy worldwide.

Benchmarking in energy reporting involves comparing a building's or facility's energy performance against similar buildings, industry standards, or its own historical data. This process helps identify areas of underperformance or excellence, setting targets for improvement and evaluating the effectiveness of energy management strategies. It provides context for energy consumption.
