Internal gain refers to the heat generated within a building from sources such as occupants, lighting, and appliances, which can contribute to the overall thermal balance and reduce the need for external heating. Understanding and managing Internal gain is crucial for optimizing energy efficiency and maintaining comfortable indoor environments in both residential and commercial buildings.
Short-term Flicker Severity (Pst) is a metric used to evaluate the impact of voltage fluctuations on lighting systems, which may cause noticeable flickering and discomfort to human observers. It is typically calculated over a 10-minute interval to ensure a robust assessment of flicker discomfort experienced in electrical systems, contributing to compliance with lighting standards and quality assurance.
