The Impact Of American Kitchen Time-Use On Urban Design And Planning: A Case Study Of Baton Rouge, Louisiana, Farshid Torabian
The Impact Of American Kitchen Time-Use On Urban Design And Planning: A Case Study Of Baton Rouge, Louisiana, Farshid Torabian
LSU Doctoral Dissertations
Over the past century, the global environment has undergone significant changes, characterized by rising temperatures and a sharp increase in greenhouse gas emissions. Parallel to these environmental shifts, the U.S. has witnessed a tripling in energy demands, underscoring the pivotal role of household consumption in the nation's carbon footprint. Within this context, the kitchen, an integral component of the American home, becomes a focal point. Given that Americans predominantly spend their time indoors, it is imperative to understand the dynamics of kitchen usage and its broader implications on energy consumption and environmental impact. To delve into this complex interplay, this …

Large-eddy simulation (LES) has proven to offer superior accuracy in regards to predicting surface pressures compared to the Reynolds-averaged Navier Stokes (RANS) models. However, the primary impediment is the high computational cost associated with LES. The authors attempt to investigate the computational cost and accuracy by employing different sub-grid scale (SGS) models in LES and hybrid RANS-LES models. One of the prerequisites of accurate pressure estimations is to ensure a horizontally homogeneous empty computational domain. This study aims to compare the computational competence qualitatively and quantitatively using an empty domain in regards to the ability to maintain horizontal homogeneity. The …

This paper focuses on the processes of wind flow in the atmospheric boundary layer, to produce realistic full-scale pressures for the design of low-rise buildings. CFD with LES turbulence closure is implemented on a scale 1:1 prototype building. A proximity study was executed computationally in CFD with LES that suggests new recommendations on the computational domain size, in front of a building model, apart from common RANS-based guidelines (e.g. COST and AIJ). Our findings suggest a location of the test building, different from existing guidelines, and the inflow boundary proximity influences pressure correlation and reproduction of peak loads. The CFD …

With the sustainability movement, vegetated building envelopes are gaining more popularity. This requires special wind effect investigations, both from sustainability and resiliency perspectives. The current paper focuses on wind load estimation on small- and full-scale trees used as part of green roofs and balconies. Small-scale wind load assessment was carried out using wind tunnel testing in a global-effect study to understand the interference effects from surrounding structures. Full-scale trees were investigated at a large open-jet facility in a local-effect study to investigate the wind-tree interaction. The effect of Reynolds number combined with shape change on the overall loads measured at …
