What aspect does building simulation software primarily assist architects with?

Building simulation software is primarily designed to assist architects in modeling energy and lighting performance. This software enables architects to create detailed simulations of how buildings will interact with environmental variables such as sunlight, temperature, and airflow. By analyzing these factors, architects can optimize energy efficiency, enhance natural lighting, and make informed decisions that lead to sustainable design practices.

Using this software, architects can evaluate various design options and their impact on energy consumption over time. This includes assessing heating, cooling, and lighting needs, which ultimately helps in designing buildings that are not only comfortable for occupants but also reduce overall operational costs and environmental impact.

While the other options may encompass relevant areas of architectural practice, they do not directly relate to the primary capability of building simulation software, which focuses on energy and lighting performance analysis.
