Which characteristic describes a simple building form?

A simple building form is characterized by having less surface area relative to its volume. This design principle typically leads to structures that are more efficient and easier to construct. Buildings with simple shapes, such as cubes or rectangular prisms, maximize their volume while minimizing the amount of surface area exposed to the environment. This reduced surface area helps to lower heat loss in cooler climates and reduce heat gain in warmer climates, contributing to energy efficiency.

In contrast, building forms that are more complex tend to have high surface areas in relation to their volumes, which can lead to increased construction costs and energy inefficiencies. Such complexity can introduce more seams and joints, which are potential points for air leakage and thermal bridging, complicating heating and cooling processes. Therefore, the focus on a simple form emphasizes efficient energy performance and potentially lower costs in both construction and maintenance.
