luqahpower site-light interaction study

Topics and analytical subjects

The topics page describes the principal analytical subjects that compose the luqahpower interaction study. It organises technical areas into measurement protocols, shading analysis, capture polygon generation, and routing interaction sketches. Each subject is presented as an observational and procedural domain: measurement protocols document instruments and sampling conventions; shading analysis explains occluder classification and horizon-profile projection; capture polygon generation details the spatial intersection operations used to derive continuous candidate regions; routing interaction sketches describe spatial pathways from capture polygons into the building fabric. The language is descriptive and non-prescriptive: the content focuses on documenting how datasets are produced and how analytical layers relate to one another as study inputs and reference outputs.

Measurement protocols

Measurement protocols specify observation procedures and instrument settings used to capture horizon profiles, panoramic imagery, and facet geometry. Protocols include sampling cadence, timestamp conventions, instrument height, and a checklist for temporary occluders. Photogrammetric inputs are recorded with camera metadata and ground control references when available. These protocols support reproducible sampling and provide provenance metadata that accompanies derived spatial layers.

Shading analysis

Shading analysis categorises occluders and generates horizon masks by sampling angular elevation across azimuth. Occluder geometry is projected along time-indexed solar vectors to produce boolean coverage schedules per facet. Outputs identify persistent exclusion zones and transient shading strips that intersect potential array corridors.

Capture polygon generation

Capture polygons are generated through geometric intersection of incident-angle envelopes with facet connectivity graphs, followed by subtraction of composite shading masks. Polygons are annotated with incident-angle statistics, time-window exposure metrics, and adjacency references for routing. The mapping preserves measurement uncertainty and provenance for each polygon.

Routing interactions

Routing interactions map potential conduit and cable pathways from capture polygons to interior junctions, documenting spatial feasibility, penetration points, and required site checks. Routing sketches emphasise interface with existing service routes and building fabric without prescribing installation techniques.

Analytical considerations and interoperability

Analytical considerations address sampling resolution, temporal sampling windows, and data interoperability. Horizon profiles sampled at one-degree azimuth resolution balance angular fidelity with storage simplicity; higher resolutions are appropriate where fine knife-edge occlusions dominate. Time-indexed sampling should capture solstitial extremes and representative clear-sky daily traces to permit envelope estimation. Interoperability notes describe common output formats and metadata fields to facilitate cross-referencing with architectural plans and photogrammetric models. The presentation remains descriptive: considerations are framed as decisions that influence data fidelity and comparative interpretation rather than as prescriptive technical specifications.
