It also uses various materials like wood and steel, equipment such as diggers, energy like electricity for power tools, land for the house, and tech tools for planning and tracking work $($Stevenson$,2024).$ For example, when we talk about how much work the workers do$,$ we can count the number of houses finished for every hour they work.
