Method & Evidence

AimTo quantify the carbon and energy footprints of prefabricated industrial buildings across their lifecycle and identify how design choices, particularly building size, influence these impacts.

MethodLife Cycle Assessment (LCA)

ProcedureA systematic cradle-to-grave LCA was conducted using site-specific data from a prefabricated building manufacturer. Four buildings of varying sizes were analyzed, and the results were used to develop a parameterized model. This model was then used to explore the impact of input parameters, including insulation, lifetime, and foundation type, across a range of industrial prefabricated building designs.

Limitations

The specific data used in the study might not apply universally to all prefabricated building systems or geographical locations.

Reliability & validity

The study's validity is supported by the model's close agreement with empirical data (within 4%). Reliability is enhanced by the systematic LCA methodology and the use of a parameterized model for broader analysis.

Think critically

How might the findings regarding the use phase's impact be mitigated through innovative design or material selection in the initial construction phase?

Design Principles

"Economies of scale in construction can lead to significant improvements in resource efficiency and reduced environmental impact per unit of built volume."

This insight is crucial for designers and engineers involved in industrial construction. It highlights that scale is a significant factor in environmental impact, suggesting that larger projects can achieve greater resource efficiency. Understanding this relationship allows for more informed design decisions that prioritize sustainability from the outset.

What This Means for Your Design

Building bigger prefabricated industrial buildings makes them better for the environment per unit of space, and how much energy they use is the biggest factor in their pollution.
