Social Interaction At The Maya Site Of Copan, Honduras: A Least Cost Approach To Configurational Analysis, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

In this article, I employ least cost paths using GIS to measure the relationship between site configuration and social connectivity at the ancient Maya site of Copan, Honduras. I investigate two questions. First, did people of different social classes experience varying degrees of social connectivity? Second, did people living in different parts of the city experience difference degrees of social connectivity? Ultimately, the goal is modify traditional configurational analysis using least cost analysis (LCA) to identify how social hierarchy was embedded in landscapes and how ancient people may have strategically manipulated landscapes to structure social interaction and community organization.

Walking In The Land Of Cars: Automobile-Pedestrian Accidents In Hillsborough County, Florida, Marc Aaron Poling

USF Tampa Graduate Theses and Dissertations

Analyses of traffic accidents are often focused on the characteristics of the accident event and hence do not take into account the broader neighborhood contexts in which accidents are located. This thesis seeks to extend empirical analyses of accidents by understanding the link between accidents and their surroundings. The case study for this thesis is Hillsborough County, Florida, within which the city of Tampa is located. The Tampa Bay region ranks very high in terms of accident rates within U.S. metropolitan areas and is also characterized by transport policies which favor private automobiles over mass transit options, making it an …

Ecological Payback Time Of An Energy-Efficient Modular Building, Jeremy Faludi, Michael Lepech

Dartmouth Scholarship

Ecological payback time was calculated for demolishing an existing commercial building with average energy performance and replacing it with an energy-efficient, prefabricated building. A life-cycle assessment was performed for a 5,000 ft2 commercial building designed by Project Frog and prefabricated in San Francisco, California, and compared to the impacts of annual energy consumption and continued status quo operation of a comparable average commercial building. Scenarios were run both with and without rooftop solar panels intended to make the prefabricated building net zero energy. The analysis considers the materials and mof the existing building, compared to continued annual energy use of …

Impacts Of Ventilation Ratio And Vent Balance On Cooling Load And Air Flow Of Naturally Ventilated Attics, Shimin Wang, Zhigang Shen

Durham School of Architectural Engineering and Construction: Faculty Publications

The impacts of ventilation ratio and vent balance on cooling load and air flow of naturally ventilated attics are studied in this paper using an unsteady computational fluid dynamics (CFD) model. Buoyancy-driven turbulent ventilations in attics of gable-roof residential buildings are simulated for typical summer conditions. Ventilation ratios from 1/400 to 1/25 combined with both balanced and unbalanced vent configurations are investigated. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively insensitive to the variations in ventilation ratio and vent configuration. The predicted temperature fields are characterized …

The Impact Of Roof Pitch And Ceiling Insulation On Cooling Load Of Naturally-Ventilated Attics, Shimin Wang, Zhigang Shen, Linxia Gu

Durham School of Architectural Engineering and Construction: Faculty Publications

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof residential buildings are investigated based on the simulation of turbulent air flow and natural convection heat transfer in attic spaces with roof pitches from 3/12 to 18/12 combined with ceiling insulation levels from R-1.2 to R-40. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively …

Development And Evaluation Of A Simplified Modeling Approach For Hydraulic Systems, Yuebin Yu, Vivian Loftness, Daihong Yu, Yan Lu, Volker Hartkopf

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents how a hydraulic system can be properly modeled for hydraulic balancing, knowledge of flow distribution, coupled simulation, and evaluation of control, etc. It focuses on water-based heating and cooling systems, which generally have high energy efficiency in design but could perform poorly in reality due to the undersensing condition and strong thermal-hydraulic coupling. The study introduces the motivation, presents the simplified modeling methodology, and illustrates the model and simulating structure. A preliminary evaluation of the method is conducted with two simple simulations. The proposed “node-branch-state” modeling approach could be easily modified, expanded and integrated into a detailed …

New Urban Living: High-Rise Vertical Farming In A Mixed Use Building, Boston, Ma, Zachary Silvia

Architecture Theses and Projects

The focus of the project is the combination of vertical farming and living in a structure that provides for itself and the surrounding community. Essentially, the result is communal living through vertical farming. To raise awareness and invite surrounding neighbors and workers into the process, the first four floors are dedicated to social interaction and a display of the systems at use. Along the path from a public market, to a café, and finally to a gathering space, visitors walk along a ramp/display of the aquaponic system.

Nature And Architecture: A Holistic Response, Jarrod Martin

Architecture Theses and Projects

The general functions of the project will be a natural healing center and research facility for natural medicine. As medical practice and theory begin to shift in the understanding on natural treatment, modern medicine facilities are becoming more environmentally friendly. Hospitals are pursuing sustainable practices as well as seeking LEED certification in the United States. Although LEED is not a necessity for this project, the natural healing center will focus on holistic care as the primary medical treatment option for patients while engaging the project in sustainable design.

Lam: Laughing My Architecture Of, Elizabeth Straub

Mathematical Modelling Of A Low Approach Evaporative Cooling Process For Space Cooling In Buildings, Medhi Nasrabadi, Donal Finn, Ben Costelloe

Conference Papers

This paper describes a mathematical model of a low approach open evaporative cooling tower for the production of high temperature indirect cooling water (14-16°C) for use in building radiant cooling and displacement ventilation systems. There are several potential approaches to model evaporative cooling, including: the Poppe method, the Merkel method and the effectiveness-NTU (ε-NTU) method. A common assumption, applied to the Merkel and ε-NTU methods, is that the effect of change in tower water mass flow rate due to evaporation is ignored, which results in a simpler model with reduced computational requirements, but with somewhat decreasedaccuracy. In this paper, a …
