In LEED, what is the significance of conducting a whole-building energy simulation?

Conducting a whole-building energy simulation is significant because it provides a comprehensive analysis of a building’s energy performance throughout its entire lifecycle. This method evaluates various factors such as the building's orientation, size, materials, systems, and operational strategies, allowing for a detailed understanding of how these elements collectively influence energy consumption and efficiency.

By assessing energy use patterns and identifying potential areas for enhancement, this simulation enables project teams to make informed decisions aimed at reducing energy demand and improving overall efficiency. The insights gained from such simulations are crucial in achieving LEED certification, as they help target energy-saving measures and optimize building performance, ultimately contributing to a more sustainable and environmentally friendly design.

The method does not primarily focus on aesthetics, local building codes, or tenant satisfaction, but rather on the technical evaluation of energy performance, which supports long-term efficiency and sustainability goals.
