7.2 Justification for material used

Acrylic sheet Lower Embodied Energy: Acrylic sheet has a lower embodied energy compared to materials like glass or metal. The manufacturing process of acrylic sheets requires less energy, resulting in a reduced environmental impact.

Energy-Efficient Production: The production of acrylic sheet involves less energy-intensive processes compared to alternatives. This lower energy requirement contributes to a reduced carbon footprint during manufacturing.

Recyclability: Acrylic sheet is recyclable, allowing for the reuse of materials and reducing the need for energy-intensive production from raw resources. Proper recycling practices can further decrease the overall embodied energy associated with acrylic sheet usage.

Lightweight Construction: Acrylic sheet is lightweight, which leads to lower transportation energy costs. Its reduced weight translates to improved energy efficiency during transportation, contributing to lower carbon emissions.

Long Lifespan: Acrylic sheet has a long lifespan and retains its physical properties over time. Its durability and resistance to degradation minimize the need for frequent replacements, resulting in lower embodied energy associated with maintenance and replacement activities.
