1) Sustainable Siting—This approach optimizes land use and development to reduce adverse impacts and minimize the building’s ecological footprint.
2) Energy Efficiency—This technique focuses on the establishment of performance targets that account for intended use, occupancy and other energy operations for new construction and renovation projects.
3) Water efficiency— This technique emphasizes the value of decreasing demands for fresh water and reducing the generation of wastewater through optimized landscaping, integrated rainwater catchments, gray water recycling, and wastewater treatment systems.
4) Building Materials—By using sustainable construction materials and resources, green building materials have aided the reduction of extraction, processing, transportation, solid waste, and consumption.
5) Healthy Indoor Environmental Quality—These processes have enhanced the sustainable communities through ventilation and thermal comfort, moisture control, daylighting, environmental tobacco smoke control, and protecting indoor air quality during construction.
