UGC NET Questions (Paper – 1)

Statements A, B, C and E are correct because they describe passive design, efficient equipment, regulatory standards and equity aspects of energy efficiency. Good orientation and design reduce loads, efficient appliances cut demand, codes guide performance and making efficient options affordable helps more households. D is wrong because retrofits can significantly improve performance, and F is wrong since audits are a key tool for environmental management. Thus, A, B, C and E only is the correct combination.

Option A:
Option A is incorrect as it omits E, ignoring how access and affordability influence who benefits from efficiency improvements. Without E, the social dimension of energy efficiency is missing from the answer.

Option B:
Option B is incorrect since it excludes A and includes only B, C and E. While those three are true, leaving out A downplays the importance of building form and orientation, which are fundamental to reducing energy needs.

Option C:
Option C is correct because it includes the full set of true statements and excludes D and F, which misrepresent retrofitting and auditing. It aligns with the integrated technical and social perspective expected in this unit.

Option D:
Option D is incorrect as it incorporates F, wrongly claiming that audits are unrelated to environmental management, and omits B. Without B, it ignores the crucial role of efficient appliances and lighting in building energy performance.
