The data file bldgpropvol1dat is a specific binary data component used by the Hazard Prediction and Assessment Capability (HPAC) software, specifically within its Second-order Closure Integrated Puff (SCIPUFF)
atmospheric dispersion model [2, 3]. It contains detailed building geometry and material property data used to simulate how hazardous releases interact with urban environments [2, 5].
Below is a structured technical paper outlining the role of this data in "hot" (high-temperature) or high-intensity urban hazard scenarios.
Technical Paper: Urban Morphological Impacts on Atmospheric Dispersion Modeling using bldgpropvol1dat 1. Introduction
In urban hazard modeling, the accuracy of predicting gas or aerosol dispersion depends heavily on the "Urban Canopy"—the complex layer of buildings and streets that disrupt airflow [3]. The bldgpropvol1dat
file serves as the primary library for building attributes within the HPAC/SCIPUFF architecture, allowing the model to transition from simple terrain layouts to complex, building-aware simulations [2, 5]. 2. Data Structure and Composition bldgpropvol1dat file (Volume 1) typically includes: Geometric Footprints
: 3D coordinates and heights of structures within specific urban grids [2]. Material Properties
: Data on surface roughness and thermal emissivity, which influence how heat is absorbed and released by the building "skin" [5]. Aerodynamic Parameters
: Coefficients that determine wake effects and downwash—the process where a plume is pulled toward the ground behind a building [3].
3. The "Hot" Scenario: Thermal Effects and High-Intensity Releases
When simulating "hot" environments—either due to extreme ambient temperatures (heatwaves) or high-energy release events (explosions/fires)—the data in bldgpropvol1dat becomes critical for two reasons: Thermal Buoyancy
: In hot climates, building surfaces heat up significantly. The model uses building property data to calculate convective heat flux, which can cause a hazardous plume to rise faster than it would over a cool, flat surface [3, 5]. Urban Heat Island (UHI) Integration
: The material properties stored in the file allow the model to account for the UHI effect, where urban centers remain hotter than rural areas, creating localized turbulence that traps pollutants at street level [3]. 4. Modeling Methodology The HPAC system ingests bldgpropvol1dat to modify the Urban Dispersion Model (UDM) : The user defines a release point. Processing : SCIPUFF queries bldgpropvol1dat to identify nearby obstacles [2]. Calculation
: The model calculates the "probabilistic" path of the plume, accounting for the "hot" thermal plumes generated by the buildings' thermal mass [3]. 5. Conclusion bldgpropvol1dat
file is indispensable for high-fidelity urban modeling. In "hot" scenarios, it ensures that simulations account for the complex interplay between building materials, high temperatures, and turbulent airflow, providing emergency responders with more accurate "hazard wedding rings" (predicted zones of impact) [1, 2].
