Key points
- Ksar Zgag El-Hadjadj employs a compact urban morphology for solar shading and wind reduction.
- A hierarchical street network modulates the microclimate within the settlement.
- Introverted courtyard typologies combine thermal mass, ventilation, and adaptive occupation.
- The settlement's bioclimatic performance is inseparable from social practices like communal maintenance and seasonal spatial use.
- Deterioration is linked to the breakdown of social practices and the use of cement interventions.

Abstract
Saharan ksour hold centuries of empirical bioclimatic knowledge, yet detailed documentation of their design principles remains scarce, particularly for non-UNESCO settlements. This research presents a multi-scalar documentation of Ksar Zgag El-Hadjadj, a fortified earthen settlement in Laghouat, Algeria. Field investigation across seasonal thermal extremes combined on-site measurement, photographic recording, and structured interviews with elderly residents retaining traditional building knowledge, analyzed for correspondence with established passive-design frameworks. The study reveals an integrated environmental system operating across scales: compact urban morphology providing solar shading and wind reduction, a hierarchical street network modulating microclimate, and an introverted courtyard typology combining thermal mass, ventilation, and adaptive occupation. Critically, this performance is inseparable from the social practices sustaining it—communal maintenance and seasonal-daily spatial use. Advanced deterioration follows directly from the breakdown of these practices, while cement interventions specifically degrade bioclimatic function. The study reframes vernacular heritage preservation as a socio-technical challenge.
