Sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It is a holistic approach that considers the economic, social, and environmental aspects of development. The concept of sustainable development was popularized in the 1987 report “Our Common Future” by the World Commission on Environment and Development, also known as the Brundtland Commission.

The three pillars of sustainable development are:

1. Economic Sustainability: Meeting the economic needs of the present without compromising the ability of future generations to meet their own economic needs.
2. Social Sustainability: Meeting the social needs of the present without compromising the ability of future generations to meet their own social needs.
3. Environmental Sustainability: Protecting the natural environment for future generations by conserving natural resources, reducing pollution, and mitigating climate change.

What is Green Building?

Green building, also known as sustainable building or environmentally friendly building, refers to the design, construction, and operation of buildings in a way that minimizes its impact on the environment. The goal of green building is to reduce the building’s ecological footprint while promoting occupant health, well-being, and productivity.

The green building movement focuses on:

1. Energy Efficiency: Reducing energy consumption through the use of renewable energy sources, efficient HVAC systems, and insulation.
2. Water Conservation: Reducing water consumption through low-flow fixtures and greywater reuse systems.
3. Waste Reduction: Reducing waste generation through recycling, composting, and minimizing packaging.
4. Indoor Air Quality: Improving indoor air quality through natural ventilation, air filtration systems, and non-toxic materials.
5. Material Selection: Selecting materials that are sustainable, recycled, recyclable, and locally sourced.
6. Land Use: Optimizing land use through compact urban planning, brownfield redevelopment, and preservation of natural habitats.
