What is a key factor in building orientation for energy efficiency?

Maximizing natural light and energy performance is a crucial element in building orientation for energy efficiency because it directly impacts a building's energy consumption and occupant comfort. When a building is oriented to take advantage of natural light, it reduces the need for artificial lighting during the day, thereby lowering energy use. Additionally, optimal orientation can enhance the building’s ability to harness solar energy for passive heating and cooling, which further contributes to energy efficiency.

Using natural light effectively can also create a healthier indoor environment, improving the well-being of the occupants. By strategically placing windows and designing the layout with orientation in mind, a designer can leverage daylight while minimizing excessive heat gain in warmer months, thus maximizing energy performance throughout the year.

Proximity to other buildings, access to public transportation, and compliance with architectural aesthetics, while important aspects to consider in urban planning and design, do not have as direct of an impact on energy efficiency as the orientation related to natural light and energy performance.
