This may have been an obvious one. Construction disrupts the natural land and environment. 11% of global energy and process-related emissions come from the production of construction materials. Transportation of the materials requires more energy consumption. Air, water, and noise pollution are potential effects of construction.
Once the building is complete and units are filled, consumption of electricity and water are affected. When maintenance is being conducted, the materials used to create the replacement parts are needed. Buildings take up 40% of the global energy consumption.
The effects are similar to the construction phase. Air, water, and noise pollution are all very real possibilities. To demolish a building energy and supplies are required. Demolition takes up 5% of the global energy consumption.
