The Decoupled Geodesic Hybrid

AbstractThe Decoupled Geodesic Hybrid introduces a dual-envelope architectural system that stratifies load-bearing, weatherproofing, and thermal control into independent layers, overcoming longstanding limitations of conventional geodesic domes. The primary layer is a material-agnostic geodesic space frame optimised purely for structural efficiency in spanning large clear areas. An independent multi-pitched planar roof provides weather protection via stratigraphic condensation management and latitude-specific minimum eave depth (e.g., 500 mm base with seasonally adjustable shading elements calculated per established solar geometry), which delivers passive solar shading, break water surface tension, and minimise facade soiling. A buffer zone moderates the microclimate around an inner Passive House-compliant envelope (n50 ≤ 0,6 h⁻¹), with perimeter options of angled triangulated panels or a vertical curtain wall with an enclosed soffit to neutralise the aerodynamic wind uplift introduced by the overhanging roof. This resolves inherent geodesic-specific failures — capillary ingress, UV degradation, and biological fouling — while safely harnessing geodesic geometry's structural economy.
