Beyond Acres: Mapping Campus Size to Academic Excellence and Space Productivity: A Critical Analysis of NIRF-Ranked Technical Institutions Using the Rational Space Index and the Land Utilisation Efficiency Index

In India, the amount of land provided to technical institutions has been regarded as an indirect indicator of institutional quality, as regulations, accreditation criteria, and planning practice for universities emphasize larger campuses. This paper questions this assumption through a three-step study. First, it reviews international research from environmental psychology, architecture, and higher education literature on how certain attributes of built environments have been correlated with measurable student performance. Second, it compares the top ten technical institutions in the 2023 National Institutional Ranking Framework (NIRF) Engineering ranking in terms of campus area, number of students, NIRF score, NAAC grade, retention rate, and design approach. Thirdly, it proposes two unique spatial productivity indicators, namely the Rational Space Index (RSI) and the Land Utilisation Efficiency Index (LUEI).For instance, Jadavpur University, with a campus spread across 84 acres, registers an RSI of 66.3 and ranks 10th in the country, while IIT Kharagpur, with a campus spread across 2,100 acres, registers an RSI of 8.2 and ranks 6th in the country. Space utilization efficiencies in these institutes average 58%, compared with an international standard of 75%, and six institutes have under-utilization gaps exceeding 20 percentage points. Given land's finite, non-renewable nature and its high opportunity cost in the institutional context, the study recommends that ranking schemes and land allocation practices prioritize spatial productivity over spatial size. Based on empirical evidence, the study suggests six recommendations, including mandatory audits of space productivity and incorporating RSI and LUEI into the NIRF framework.
