Energy efficiency (EE) in the construction sector is crucial for sustainable development, particularly in emerging economies like Pakistan, where the industry accounts for a large share of energy consumption and environmental degradation. Despite its economic significance, Pakistan’s construction sector suffers from inefficiencies in energy use, with limited comprehensive assessments to guide improvements. This research introduces a novel, integrated approach combining Data Envelopment Analysis (DEA) and Tobit regression to evaluate and enhance EE in construction projects. DEA was applied to data from 120 construction firms, revealing an average technical efficiency (TE) of 84.4%, pure technical efficiency (PTE) of 93.2%, and scale efficiency (SE) of 90.4%, highlighting notable inefficiencies. The Tobit regression analysis identifies key factors influencing EE, including contractor training, access to loans, experience, and project site distance. This dual-method framework not only measures EE but also provides actionable insights to address inefficiencies, offering practical implications for policymakers and industry stakeholders. The findings emphasize the need for targeted interventions, such as government-supported financing and contractor training programs, to promote energy-efficient practices in Pakistan’s construction sector. This approach provides a replicable model for other developing economies seeking sustainable construction practices.

The United States, long revered as a paragon of higher education, has faced its share of tumultuous enrollment scandals that reveal the cracks within even the most celebrated systems. These scandals, encompassing everything from financial malpractices in for-profit colleges to falsified public school enrollment data, carry valuable insights. For Pakistan, a nation grappling with its own education challenges, the lessons from these events could be transformative if studied and adapted with care.

Pakistan’s economy collapses, reaching the point of default or bankruptcy. Then, some visible and some invisible hands come to its rescue. The economy first comes out of the borderline default. Gradually, it stabilises and shows a sign of growth. While the growth is going upward, when one a fine morning, we come to know that the economy has collapsed. This has been ongoing for the last several decades. Economic renewal is no small task. It demands vision, boldness and unyielding determination.
