Green buildings and housing design – UGC NET Question

Statements A, B and D are correct because they describe the core goals, design strategies and certification mechanisms of green buildings. Green housing focuses on reduced resource use and better indoor quality, uses passive design and efficient technologies and is evaluated by rating systems that apply performance criteria. Statement C is incorrect since life-cycle assessment of materials is an important tool to understand embodied energy and environmental impacts over a building’s life. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incorrect as it includes A and B but omits D. While it captures goals and design features, it ignores the role of certification systems in encouraging and benchmarking green building performance. Because one correct statement is missing, the option is incomplete.

Option B:
Option B is incorrect because it selects only B and D. Although both are correct, it leaves out A, which states the overall aim of green buildings and is central to the concept. Without A, the description of green buildings is partial.

Option C:
Option C is incorrect as it includes C, which wrongly claims life-cycle assessment is irrelevant. Life-cycle thinking is widely emphasised in sustainable construction, so accepting C makes the option conceptually flawed.

Option D:
Option D is correct since it covers goals, design measures and certification aspects while excluding the incorrect dismissal of life-cycle assessment. It thus presents a comprehensive and accurate picture of green buildings.
