When selecting course materials, which factor is NOT essential to consider?

When selecting course materials, the cost of installation is not always considered essential compared to other factors such as durability, maintenance requirements, and environmental impact. Durability is crucial as it determines how well the materials will withstand weather conditions and regular use, which directly impacts the longevity of the facility. Maintenance requirements are important because materials that require frequent upkeep can lead to increased long-term costs and operational challenges, affecting overall facility management. Environmental impact has gained significant importance due to sustainability initiatives, and choosing materials that have a lower environmental footprint aligns with best practices in facility management. While installation costs are certainly a factor to consider, they may not carry the same level of critical importance in the selection process, particularly if the alternative materials offer superior benefits in the other essential areas.
