Exterior design is the art and science of designing the exterior of a building. It encompasses the overall look and feel of the building, including the materials used, the colors, the style, and the way the building interacts with its surroundings.

Exterior design is important for a number of reasons. First, it can help to create a first impression that is both attractive and inviting. Second, it can help to protect the building from the elements. Third, it can help to improve the energy efficiency of the building.

There are a number of factors that can be considered when designing the exterior of a building. These include the climate, the surrounding environment, the purpose of the building, and the budget.

The climate is an important consideration because it will determine the materials that can be used and the style of the building. For example, a building in a hot climate will need to be made of materials that reflect heat, while a building in a cold climate will need to be made of materials that retain heat.
