What does the term "Building Lifecycle" primarily focus on?

The term "Building Lifecycle" primarily focuses on the various phases from construction to decommissioning. This concept encompasses all stages of a building’s existence, starting from the initial design and construction, moving through its operational use, maintenance, and eventually to its demolition or recycling. Each phase presents distinct challenges and opportunities, particularly in relation to sustainability and environmental impact.

Understanding the Building Lifecycle is crucial for implementing effective sustainability practices, as it allows stakeholders to assess how decisions made during design and construction can affect the building's efficiency, lifespan, and environmental footprint throughout its operational life, and ultimately how it is disposed of once it reaches the end of its useful life.

The other options, while related to aspects of buildings, do not encapsulate the comprehensive approach that the concept of the Building Lifecycle emphasizes. The architectural style, economic factors, and aesthetics represent specific considerations within the broader framework, but they do not capture the full journey and implications of a building’s existence in relation to sustainability and design.
