From precedent to performance: A coded comparative analysis of climate-responsive façade strategies in ten contemporary Indian school buildings

Abstract

Architectural precedents are widely used to guide climate-responsive school design in India, yet the evidential status of what they communicate is rarely examined. This study analyses ten contemporary school buildings (pre-school, primary-secondary and special-needs) completed between 2013 and 2024 across hot-dry, composite, warm-humid and temperate climates. Published project documentation was coded against a twelve-strategy façade codebook that distinguishes strategies stated by designers from those identifiable only in drawings or photographs. Prevalence, co-occurrence and climate stratification were then analysed, and each strategy was mapped against peer-reviewed performance evidence retrieved through a structured search of 2015-2026 literature. Courtyards (8 of 10 cases), jaali screens (7) and high-mass masonry or earth envelopes (7) dominated, and frequently appeared together. Out of 59 strategy instances, 24 (41%) were visible but never articulated in project texts; recessed openings, which are present in five cases, were never stated at all. No case reported measured performance, and the only two numerical claims were unverified. The evidence map shows that the most common strategies, jaalis and massive envelopes, have no peer-reviewed evaluation in Indian school buildings, while the most influential envelope parameter in the international literature, window-to-wall ratio, was not reported by any case. Two climate misfits were identified: a lightweight envelope in a hot-dry setting and high-mass walling in warm-humid settings. The study argues that precedents should be treated as hypotheses rather than evidence, and it proposes a translation framework that converts each recurring strategy into measurable parameters, performance metrics and evaluation methods for the next research phase.
