Rethinking Extensive Green Roofs To Lessen Emphasis On Above-Ground Biomass, Richard K. Sutton
Landscape Architecture Program: Faculty Scholarly and Creative Activity
In the future, most green roof applications will not be highly visible, yet these roofs will still provide the benefits of heat island reduction, stormwater control and biodiversity for hard-surfaced cities. However, human bias in wanting more biomass and visible blooms leads green roof horticulturalists and their approach of maximizing those aspects down a slippery slope that, in turn, leads to increased hours of labor, over-watering and fertilizing and specifying too many cultivars

Seeding Green Roofs With Native Grasses, Richard K. Sutton
Landscape Architecture Program: Faculty Scholarly and Creative Activity
During six years of native grass establishment and growth on four green roofs, we sought to understand appropriate seeding seasons and spacing, the amount of time to reach the industry 80% coverage threshold (FLL 2008), the seed yield projections for volunteer plant infill. We also produced and tested methods for successfully and inexpensively seeding and determined “as needed” irrigation protocols. The suite of techniques examined improves and enhances the use, establishment, and management of native grasses on green roofs and reduces green roof costs.

Postcyclic Behavior Of Low-Plasticity Silt With Limited Excess Pore Pressures, Shuying Wang, Ronaldo Luna, Junsheng Yang
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
This paper investigates the post cyclic behavior of low-plasticity silt with excess pore pressure ratio (Ru) less than 1. The testing specimens were prepared from Mississippi River Valley (MRV) silt. Full and no reconsolidation were allowed after specimens were subjected to various excess pore pressure ratios due to cyclic loading in a cyclic triaxial cell, and then monotonic shear tests were conducted. The effect of the Ru on shear strength and stiffness at small and large deformation was investigated. It was found that a Ru greater than 0.70 is a prerequisite of large increase in volumetric strain and undrained shear …

Linking Effective Whole Life Cycle Cost Data To Parametric Building Information Models Using Bim Technologies, Dermot Kehily, Trevor Woods, Fiacra P. Mcdonnell
Conference papers
Abstract ̶ This paper demonstrates the capabilities of BIM (Building Information Modeling) in leveraging Whole Life Cycle Cost (WLCC) data requirements to perform WLCC calculations and produce WLLC estimates. The research determines the extent to which WLCC data, such as time, interest rates, escalation rates and real costs can be attached to parametric BIM data to be used effectively to create speedier and more accurate real-time WLLC analysis. Without incorporating WLCC data in the BIM, a complete picture of a construction project’s WLCC cannot be formed from the default outputs of the model. BIM 5D applications such as CostX utilise …

Approximating The Seismic Amplification Effects Experienced By Solar Towers Mounted On The Rooftops Of Low-Rise Industrial Buildings, Peter Luiz Balla
Master's Theses
This thesis investigates the acceleration amplification experienced by solar towers mounted on the rooftops of low-rise industrial buildings during a seismic event. Specifically, this thesis looks to assess the validity of using amplification factors adopted by the ASCE 7-05Minimum Design Loads for Buildings and Other Structures to approximate seismic acceleration amplification for roof-mounted solar towers. To investigate the validity of the ASCE 7-05 amplification factors, this thesis conducts timehistory analyses of three theoretical solar towers mounted on the roof of a case study building. The time history analyses are conducted in the finite element computer modeling program SAP 2000 using …

Planning For Drought-Resilient Communities: Evaluating The Fastest Growing Counties’ Local Comprehensive Plans, Xinyu Fu
Community and Regional Planning Program: Theses
Recent drought events across the United States illustrate the country’s changing and continuing vulnerability to drought. Drought impacts are often associated with unsustainable land use and poor water management practices, but research has been conducted on how well localities prepare for drought in building long-term resilience through land use planning and what jurisdictional factors correlate with their quality in drought planning. Targeting the fastest growing counties, due to their high possibility in increasing drought risk by making unwise land use decisions, this paper analyzes 61 selected county comprehensive plans from the research sample against a conceptualized drought-ready protocol, and examines …

Capital Cost Comparisons Between Low Impact Development (Lid) And Conventional Stormwater Management Systems In Florida, Daniel C. Penniman, Mark Hostetler, Tatiana Borisova, Glenn Acomb
Suburban Sustainability
Low impact development (LID), an ecologically sensitive development strategy and stormwater management (SWM) method, is beginning to be implemented in more suburban and metropolitan projects. However, construction firms that work in Florida have been relatively slow to adopt LID. One significant reason being that many professionals in the development community believe LID practices raise the cost of construction compared to conventional, “pipe and pond” methods. Our objective for this study was to determine how specific capital costs differed between LID and conventional SWM methods. We surveyed a group of LID-experienced design professionals to collect cost data from projects that were …

The Utilization Of Social Spaces Near Soccer Fields By Attendees Of Hispanic Soccer League Matches In Dallas, Texas, Blake Samper
Landscape Architecture Masters & Design Theses - Archive
The purpose of this research is to observe and identify the social interactions in pedestrian spaces immediately surrounding soccer fields during Hispanic soccer league matches in Dallas, Texas. The research uses passive observation of spectators at Hispanic soccer league matches in the Dallas area to determine which activities are prevalent and which types of spaces are most commonly used and for what purpose. Recent immigration has greatly boosted the numbers of Hispanics living in North Central Texas (Price & Whitworth, 2004). This population increase is leading to wide demographic changes where immigrants settle. One of these shifts is occurring in …

Absorption Simulation ( Absim ) Software Development, Vipul Vishnu Bhat, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Researchers working on air conditioning systems currently use a software called ABSIM ( Absorption Simulation ) to evaluate current absorption systems or simulate new system designs. ABSIM was developed at Oak Ridge National Labs in the 1980s and the latest platform it is compatible with is Windows XP. ABSIM is not compatible on newer platforms and is not very user friendly. A lot of the actions involved in using ABSIM aren’t very intuitive. The goal is to develop a more user friendly simulation program that is based off of ABSIM and see to it that the program can be deployed …

Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …
