How do green buildings save energy?

Green buildings use energy-efficient lighting, appliances, and systems to reduce the amount of energy they consume. They often feature double glazing, insulation, and airtight seals to minimize heat loss, which can help keep cooling and heating costs down.

Green buildings also rely on renewable energy sources like solar or wind power, instead of non-renewable sources like fossil fuels. Additionally, green buildings often feature green roofs that absorb and store rainwater for reuse, as well as reflective surfaces to reduce temperatures during hot months.
