1. Solar Panels: Solar panels can be installed on roofs or walls of a building to generate electricity from the sun.
2. Wind Turbines: Wind turbines can be installed on tall buildings or in open spaces around the building to generate electricity from wind power.
3. Geothermal Heating and Cooling: Geothermal systems can be used to heat and cool a building by using the natural heat from the earth.
4. Passive Solar Design: Passive solar design involves designing a building to maximize solar gain and reduce heat loss through the use of materials, orientation, and window placement.
5. Green Roofs: Green roofs can be installed on top of a building to provide insulation, absorb rainwater, and reduce the urban heat island effect.
6. Efficient Lighting: LED lighting can be used in a building to reduce energy consumption and lower electricity bills.
7. Water-saving fixtures: Low-flow toilets and faucets can be installed in a building to reduce water consumption.
8. Renewable Energy Procurement: A building can procure renewable energy through purchasing green power from an electricity supplier or installing on-site renewable energy sources.
9. Energy-efficient HVAC systems: Energy-efficient heating, ventilation, and air conditioning (HVAC) systems can be installed to reduce energy consumption.
10. Energy-efficient building materials: Building materials that are sustainable, efficient, and can reduce the energy needed to heat and cool a building should be used.
