A Critical Assessment Of Concrete And Masonry Structures For Reconstruction After Seismic Events In Developing Countries, Heather Mcwilliams, Corey T. Griffin

Research-Based Design Initiative

Overview: The infrastructures of developing countries, old and new, are in severe danger of the next natural disaster, only due to the fact that there is zero concern for the overall use of materials. And although the awa reness of poor construction tech niques have been presented, engineers and arch itects are continuously proposing systems tha t are destined to be hazards once the next disaster hits. Not only is the use of concrete economica lly unsustainable, but it is also the most vulnerable material when seismic activity hits the surface. As the international community helps developing countries such as …

Efficacy Of Replacement Windows In Building Energy Retrofits: A Post Occupancy Evaluation, Chris Rockhill, Heidi Crespi, Corey T. Griffin, Boora Architecture

Research-Based Design Initiative

The thermal performance of replacement windows has made considerable progress in a short time frame. Few studies have been carried out with regard to application of new and retrofit windows to pre-retrofit windows. The goal for this energy retrofit is occupant comfort, as 80% of a buildings energy use goes toward maintaining this standard.Any effort to make this load more efficient is worth investing and warrant post occupancy evaluation to make more informed decisions about future investments. This study gives great insight into the potentials, positives and negatives for utilization and employment of data loggers with thermal couples, infrared thermography, …

A Multi-Performance Comparison Of Long-Span Structural Systems, E. Douville, B. Thompson, Corey T. Griffin, Kpff Consulting Engineers

Research-Based Design Initiative

When a building requires a long span, especially on the ground floor of a multi-story building, the long span often determines the structural system used early in the design pro-cess without any other consideration. Commercial and residential buildings are responsible for roughly 40% of all carbon emissions and energy use, more than any other sector in the USA. Moreover, this excludes the significant energy and emissions required to extract, process, trans-port and assemble building components. Globally, the production of cement alone accounts for 4% of carbon dioxide emissions. Consequently, reducing the environmental impact of building construction and operations is critical …

Comparing The Embodied Energy Of Structural Systems In Parking Garages An Analysis Of Three Built Projects: Cellular Steel, Precast Concrete And Post-Tensioned Concrete, Corey T. Griffin, L. Bynum, A. Green, S. Marandyuk, J. Namgung, Kpff Consulting Engineers

Research-Based Design Initiative

The structure of a typical office building contributes roughly one-quarter to one-third of the total embodied energy. Although the occupation phase of a building’s life cycle currently dominates energy use, as operational energy use is minimized through high-performance design, construction and equipment, embodied energy will play a larger role in the overall energy consumption of a building. Consequently, the structural system should be a primary target for reducing the embodied energy of a building. Parking garages offer an ideal case study for comparing the embodied energy of a variety of structural systems. As above grade parking garages have little operational …

The Role Of Structures In Daylighting Retrofits For Existing Buildings: Exploring An Iterative Workflow For The Schematic Design Phase In Building Retrofits, Portland State University. School Of Architecture

Research-Based Design Initiative

Existing buildings, particularly those with deep floor plates, must be retrofitted to reduce electricity consumption. The structural systems of existing buildings can both inhibit and support daylighting retrofits, specifically the use of skylights. This research explores the interactions of structural systems and daylighting through the use of simulation software, specifically the ability of structure to reduce glare by blocking direct sunlight and distributing light more evenly.

Computational Modeling Of Baffled Disinfection Tanks, Zachary H. Taylor, Qing Xu, Jordan M. Wilson, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The present study focuses on understanding the flow dynamics of baffled disinfection contact tanks through the use of computational fluid dynamics (CFD). In particular, we seek to address the key question: for a given footprint of a contact tank with a fixed inlet configuration, how does the hydraulic efficiency of the tank depend on the configuration of internal baffles? The benchmark contact tank geometry in our study is shown in Figure 1. In order to define guidelines for hydraulically efficient baffle tanks, we perform a total of 36 high-resolution three-dimensional simulations to quantify the efficiency of a laboratory scale tank …

Roof Drainage: Not My Problem ... Maybe, John Lawson

Architectural Engineering

Many structural engineers are surprised to learn that the International Building Code (IBC, 2009) requires the roof structure to be engineered for standing water weight in the vicinity of the drains and scuppers regardless of roof slope. In addition, some low-slope roofs also require special attention for water weight and stiffness for safety against ponding failures or protection against accelerated roofing deterioration. With a mixture of overlapping design disciplines between the architect, plumbing consultant and structural engineer, proper roof drainage is often not fully addressed in building design and can lead to catastrophic collapse.

Investigating Self-Cooling Effects Of Ventilated Attics Under Different Roof And Ambient Temperatures In Summer, Zhigang Shen, Shimin Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

An unsteady computational fluid dynamics model is employed to simulate summer-time buoyancy-driven turbulent ventilation in gable-roof attics of residential buildings. The energy performance of vented attics is assessed by comparing their performance to sealed attics with the same geometry and insulation configurations. The simulated boundary conditions of the roof-top temperature ranging between 295.15 K and 345.15 K, coupled with an ambient temperature ranging between 295.15 K and 315.15 K, resemble the summer attic conditions with effects of solar irradiance on the roofs. Simulation results indicate that both the vented and sealed attics are dominated by thermal stratification. The cooling load …

Cal Viva: Assessing The Seismic Vulnerablility Of California's State-Owned Buildings, James Guthrie, Jill Nelson

Architectural Engineering

In the last 20 years, agencies and departments in the State of California have initiated seismic vulnerability programs for state-owned buildings with goals ranging from life safety to reduced post-earthquake disruption. Until now, there has not been an assessment of all state-owned buildings with the goal of identifying and assessing the seismic vulnerability of those buildings needed for response and recovery efforts after an earthquake.

The California Vital Infrastructure Vulnerability Assessment Project (Cal VIVA), sponsored by the California Emergency Management Agency (Cal EMA) and funded through FEMA, has developed a statewide approach to assessing the vulnerability of the state-owned building …
