ISO 7730 is an international standard that provides guidelines for assessing and ensuring thermal comfort in buildings based on the Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) indices. It is widely used by architects and engineers to design and evaluate indoor environments to enhance occupant comfort and energy efficiency.

Occupant comfort is a holistic measure of how well a built environment supports the well-being and satisfaction of its users, encompassing thermal, acoustic, visual, and air quality factors. It is crucial for designing spaces that enhance productivity, health, and overall quality of life, requiring a balance between subjective perceptions and objective environmental parameters.

Occupant Comfort

Energy efficiency refers to using less energy to perform the same task or produce the same outcome, thereby reducing energy waste and lowering energy costs. It is a crucial component in combating climate change and enhancing energy security by minimizing the environmental impact of energy consumption.
