Expanding the research and awareness on the contribution to and affect of design and architecture on health and activity promotion in the workplace (h&ap) is essential in moving forward in the design of working environments. As humans, we spend the majority of our time indoors, for an average American adult he or she spends the majority of the day in a working environment. The impact that our spaces have is much deeper than the aesthetic. Our environments can depict how we act, feel and operate based on the design of our surroundings. Through this research, the goal was to study …

Revitalization Of Urban Alleys, Shusei Kakimoto

Community and Regional Planning Program: Theses and Student Projects

Alley revitalization is becoming more widely acknowledged as a viable urban redevelopment strategy in United States cities. Currently, most alleys in U.S. cities are underutilized, and they evoke a number of negative images—fearful places, waste-strewn, stinky, etc. The successful revitalization of alleys presents many benefits, such as economic development, enhanced walkability, visual enhancement, reduction of crime, etc. Revitalization of alleys leads to more productive and effective utilization of public space. In fact, cities in many countries have long utilized alleys as places where many aspects of ordinary daily life of the city take place. However, the potentials of alleys and …

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.

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

Landscape Architecture Program: Faculty Scholarly and Creative Activity

Background readings on scale plus twenty-three visual landscape assessment studies from 1968 to 2006 were examined to understand the nature and use of scale and its relationship to the visual environment. The objectives of this study were to: 1) describe the concept of scale as applied to visual assessments, 2) review scale use in selected visual assessments, and 3) identify issues that need further research to better integrate scale into visual landscape assessments and landscape ecological theory.

Basic concepts and features relating observers with landscape and scale required defining scale, bounding visibility, perceiving scale, seeing hierarchically, and visualizing grain and …

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

Transforming Architecture: Engaging The Built Environment, Ryan G. Hier

Architecture Masters of Science Program: Theses

Contemporary society is transfixed by the newest piece of technology. More often than not these devices serve as commodities; eliminating a certain amount of burden from daily life. The architectural realm is no different. Building design decisions are constantly scruti­nized by their ability to perform, with respect to energy consumption and conservation. However, there is a different type of building performance worth considering: the act of transformation. Transformable architecture has the abili­ty to change structure, space, and function through physical movement of the architecture.

In an age where technology suc­ceeds in disengaging humans from interaction with each other, it can …

Boomtown: A Momentary Community, Elizabeth G. Hawks

Architecture Masters of Science Program: Theses

“Gillette Syndrome” describes a condition within a city undergoing rapid growth, usually due to the introduction of a new industry within the city or more specifically, the extraction of a newly discovered natural resource. Symptoms of the syndrome are an increase in crime and decay within a city and a decrease in community identity.

Global oil prices continue to rise as the resource becomes more difficult to extract from the earth’s layers. The new price of oil necessitates the extraction of crude through methods that were previously too expensive to justify.

These new methods are utilized for extracting oil in …

Rating Low Levels Of Ambient Noise In Performing Arts Facilities, Lily M. Wang, Brent A. Kraay

Durham School of Architectural Engineering and Construction: Faculty Publications

Previous studies have indicated that common indoor noise rating metrics, such as Noise Criteria NC and Room Criteria RC, do not best correlate to human perceptions of annoyance and distraction in typical office environments. Based on investigations conducted at the University of Nebraska using noise levels between 30 – 60 dBA, the author has proposed that an effective indoor noise rating method should begin with a rating of level (either dBA or sones), then an assessment of spectral quality, tones, and fluctuations. How well would such a system work at very low levels of ambient noise, though, as found in …

Quantifying The Just Noticeable Difference Of Reverberation Time With Band-Limited Noise Centered Around 1000 Hz Using A Transformed Up-Down Adaptive Method, Matthew G. Blevins, Adam T. Buck, Zhao Peng, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

This study seeks to quantify the just noticeable difference (JND) of reverberation time (RT) using band-limited noise. ISO 3382-1 lists the JND of reverberation metrics at 5% based on work by Seraphim (1958). However, others have found the JND of RT to be higher from 6% to 39%. Many of these studies utilized band-limited stimuli, e.g. speech, music motifs and bandlimited noise. A previous study by the authors conducted on 30 subjects using white noise demonstrated a JND of RT at 22%. To further verify these results and investigate potential upward frequency masking, the present study was conducted following the …

Durham School of Architectural Engineering and Construction: Faculty Publications

This research experiment aims to better quantify human perception and performance under increased background noise levels of varying intervals. Twenty-seven participants were tested over five 30 minute sessions where they were subjected to RC-29(H) and RC-47(RV) conditions created by broadband noise fluctuating on different time intervals. These intervals varied from two minutes to ten minutes, simulating the conditions of a noisy HVAC system turning on and off. The performance results of an arithmetic test dealing with short-term memory and a subjective questionnaire will be presented and compared to a similar test using broadband noise bursts and correlated to noise metrics …

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Zhao Peng, Lily M. Wang, Siu Kit Lau, Adam M. Steinbach

Durham School of Architectural Engineering and Construction: Faculty Publications

Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper …

Water And The Architect: Architecture As Decentralized Water Management, Daniel A. Williamson

Architecture Masters of Science Program: Theses

Water is the essence of life, a material, a resource, a commodity. It is volatile, fragile, devastating, nourishing and is ultimately spatial. The design of how water spatially inhabits, flows, and interacts with our built life has seen many forms, functions, systems, failures and successes. Over the course of history those who have had the opportunity to define our relationship with water has spread across numerous disciplines, and touched many professions. The architectural relationship with water has seen an unfortunate bifurcation over the past two centuries. It is this separation of architecture from adequately and actively engaging water management, primarily …

Lexiconic: Reading The Edifice, Amanda L. Mejstrik

Architecture Masters of Science Program: Theses

Language has undergone an evolution similar to architecture. Both have been defined through multiple styles which have a tendency to change and reestablish themselves based on popular culture, eventually permeating through society, while subsequently losing momentum and necessity. In the same way that architecture has transitioned through time based on a societal importance of efficiency, economy, and effectiveness, language begins to assume a new oratory standard.

The Emergent In-Between, Gregory R. Gettman

Architecture Masters of Science Program: Theses

As walkability becomes a more critical aspect of the organization of urban environments, it is essential that architects engage in the development of the spaces people actually occupy (the ‘in-between’) as well as the relationship between the programs they border. Using walkability as a catalyst, this thesis seeks to design a system for growing new urban tissue. Within that tissue are networks and proximities of activities that define the means and destinations of walking, as well as the spatial condition that makes the condition appealing for walking. Such a system should be able to define and optimize program organizations and …

Architecture Masters of Science Program: Theses

This project generates an alternative model of high-density development for emerging metropolitan areas that increases the intensity of use and overall density of a site while simultaneously producing new types of public open space.

Focused intently on ways in which urban form influences or impacts a city’s consumption of energy and resources, the project can be understood as a formal approach to sustainability in which basic formal or tectonic properties are examined in favor of technological building systems.

Ultimately, the project redefines the relationship between the park and the city, creating a network of public open spaces through the intensification …

Precast/Prestressed Concrete Truss-Girder For Roof Applications, Peter S. Samir

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

Steel trusses are the most popular system for supporting long span roofs in commercial buildings, such as warehouses and aircraft hangars. There are several advantages of steel trusses, such as lightweight, ease of handling and erection, and geometric flexibility. However, they have some drawbacks, such as high material and maintenance cost, and low fire resistance. In this paper, a precast concrete truss is proposed as an alternative to steel trusses for spans up to 160 ft. without intermediate supports. The proposed design is easy to produce and has lower construction and maintenance costs than steel trusses. The proposed design is …

Transparency: The Unspoken Design Element -- How Levels Of Visibility Affect Adult Learning And Sharing, Erica M. Bartels
