Introduction to Sustainable Architecture
I associate sustainable architecture with a design philosophy that embodies the ideas of environmental, social and economic sustainability. It is an idea in the field of architecture that tries to reduce pollution from buildings through improvement on efficiency and moderation with respect to materials, energy, space used for building. Sustainable architecture is not a mere fad; it represents an inevitable transformation in the way we plan and develop spaces for dwelling, laboring, or recreation.
Sustainability is of utmost importance in the modern world. The needs of buildings are bound to increase in proportion with the population projected to reach over nine billion people by 2050. This increase requires a shift in paradigm towards sustainable practices to avoid losing every resource we have and damaging our planet. The World Green Building Council estimates that buildings are responsible for 39% of global energy-related carbon emissions, comprising the operational stage in 28%, and materials & construction being at an amount equal to approximately only 10%. This very statistic highlights the importance of sustainable architecture as a priority in our future.
Today’s sustainable architecture is setting the path toward an eco-friendly future by implementing new design concepts helping to reduce waste, cut down on energy use and create better living conditions for tenants. For instance, solar panels shown above is a common practice in sustainable building designs. These panels generate energy from the sun, thereby reducing dependence on fossil fuels and minimizing greenhouse emissions. Further, sustainable architecture usually includes elements like green roofs, rainwater harvesting systems and materials grabbed from conscientious suppliers among other factors towards a stable built environment.
