  Planning is a pivotal ability of any intelligent system being developed for
real-world applications. AI planning is concerned with researching and
developing planning systems that automatically compute plans that satisfy some
user objective. Identifying and understanding the relevant and realistic
aspects that characterise real-world application domains are crucial to the
development of AI planning systems. This provides guidance to knowledge
engineers and software engineers in the process of designing, identifying, and
categorising resources required for the development process. To the best of our
knowledge, such support does not exist. We address this research gap by
developing a conceptual framework that identifies and categorises the aspects
of real-world planning domains in varying levels of granularity. Our framework
provides not only a common terminology but also a comprehensive overview of a
broad range of planning aspects exemplified using the domain of sustainable
buildings as a prominent application domain of AI planning. The framework has
the potential to impact the design, development, and applicability of AI
planning systems in real-world application domains.
