Green building characteristics – UGC NET Question

Green buildings aim to reduce environmental impacts over the entire life cycle of a structure. They incorporate features such as proper insulation, passive solar design, rainwater harvesting, low-flow fixtures, non-toxic materials and ventilation systems that maintain healthy indoor conditions. These features help save energy and water, reduce waste and improve occupant well-being.

Option A:
Option A is incorrect because heavy use of energy-intensive materials without insulation typically increases a building’s ecological footprint and operating energy demand.

Option B:
Option B is correct as it summarises the central concerns of energy efficiency, water conservation and healthy indoor environments, alongside careful material choices.

Option C:
Option C is incorrect since sealing windows to exclude natural light and fresh air raises dependence on artificial lighting and mechanical ventilation, increasing energy use and potentially harming indoor air quality.

Option D:
Option D is incorrect because green building practice often seeks to integrate landscaping, trees and pervious surfaces, not eliminate them.
