This release accompanies the paper "3D Façade Geometry as a Dual Passive Control in Hot Urban Canyons: Reducing Street MRT and Cooling Loads." It contains two complementary Grasshopper (.gh) definition files: experiment 1.gh ("indoor"): builds a discretised 60 m × 15 m façade with a 3 m module and exports the geometry to EnergyPlus via Honeybee–EnergyPlus. It simulates conductive heat flux and cooling loads under fixed material properties, boundary conditions and IdealLoadsAirSystem settings. experiment 2.gh ("outdoor"): uses Honeybee–Radiance to perform high‑fidelity ray tracing based on the EnergyPlus output. It evaluates mean radiant temperature (MRT) and the Universal Thermal Climate Index (UTCI) across a 1.5 m-high sensor grid, and decomposes MRT into short- and long-wave components. Both scripts share a canonical street‑canyon geometry (H/W = 1.0) and allow you to adjust façade morphology (flat, pixelated, wedge, carved or wavy), recess depth, orientation, weather file and simulation period. Together they provide a dual-scale assessment of complex façades by coupling indoor energy and outdoor microclimate simulations.

Abstract
This release accompanies the paper "3D Façade Geometry as a Dual Passive Control in Hot Urban Canyons: Reducing Street MRT and Cooling Loads." It contains two complementary Grasshopper (.gh) definition files: experiment 1.gh ("indoor"): builds a discretised 60 m × 15 m façade with a 3 m module and exports the geometry to EnergyPlus via Honeybee–EnergyPlus. It simulates conductive heat flux and cooling loads under fixed material properties, boundary conditions and IdealLoadsAirSystem settings. experiment 2.gh ("outdoor"): uses Honeybee–Radiance to perform high‑fidelity ray tracing based on the EnergyPlus output. It evaluates mean radiant temperature (MRT) and the Universal Thermal Climate Index (UTCI) across a 1.5 m-high sensor grid, and decomposes MRT into short- and long-wave components. Both scripts share a canonical street‑canyon geometry (H/W = 1.0) and allow you to adjust façade morphology (flat, pixelated, wedge, carved or wavy), recess depth, orientation, weather file and simulation period. Together they provide a dual-scale assessment of complex façades by coupling indoor energy and outdoor microclimate simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
