What is a key characteristic of green architecture?

A key characteristic of green architecture is its focus on prioritizing energy efficiency and reducing environmental impact in building designs. This approach integrates sustainable practices that aim to minimize the ecological footprint of buildings throughout their lifecycle. Green architecture incorporates techniques such as using renewable energy sources, improving insulation to reduce energy consumption, and selecting materials that are sustainable and have lower environmental impacts.

By emphasizing energy efficiency, green architecture not only helps mitigate climate change but also promotes healthier living environments and can lead to economic benefits through reduced utility costs. This holistic approach contrasts sharply with the other options that do not align with the principles of sustainability and long-term ecological responsibility that characterize green architecture.
