Building life cycle refers to the view of a
building
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and fu ...

A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design' ...

The study of the entire impact of a building on its environment has become a de facto requirement for construction in most jurisdictions,
owing to the resource-intensive nature of construction. Life cycle analysis considers various aspects of resource utilization in a building, for example, overall
energy conservation. Current research is focused on exploring methods of incorporating a whole life cycle view of buildings.
It is considered a subset of

Life cycle assessment or LCA (also known as life cycle analysis) is a methodology for assessing environmental impacts associated with all the stages of the life cycle of a commercial product, process, or service. For instance, in the case o ...

History
The concept of life cycle analysis evolved since the concept was initially considered in the 1970s and 1980s,
when life cycle studies focused on the quantifying the energy and raw resources used by a building, and the load on the sewerage and sanitation systems imposed by waste generated in the building, during the operational life of the structure. Since then, the methods of analysis has evolved, and presently comprises four stages - definition of scope, inventory analysis and life cycle impact assessment.
In the period from 2000 to 2014, studies on sustainable building strategies, for example, energy consumption, specific components of construction, materials, environmental impacts of building subsystems, integrated renewable energy systems, and electrical and thermal systems have been conducted, with the number of publications rising monotonically.
