What is the term for buildings that are 15 meters or more in height?

The term "High-Rise Building" specifically refers to structures that are typically defined as being 15 meters or more in height. This classification is significant in the field of fire protection and safety, as high-rise buildings present unique challenges in terms of fire suppression and evacuation due to their increased height and complexity. In many building codes and fire safety regulations, the designation of a building as a high-rise necessitates specific construction standards, fire protection systems, and emergency response strategies that differ from those required for shorter structures.

Other terms like "Multi-Story Structure" and "Tall Building" can be used in broader contexts and may not have a universally accepted height threshold. "Skyscraper" tends to refer to very tall buildings, often above 100 meters, but is less precise than the definition of high-rise. Therefore, when referring to buildings that meet the specified height of 15 meters or more, "High-Rise Building" is the most accurate and widely recognized term in the industry.
