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 …

Preferred Iconography For Development Of New Garden Identity, Mina Kaboudarahangi, Osman Mohd Tahir, Mustafa Kamal M.S

Mina Kaboudarahangi

The intention of this study is to highlight the importance of garden in creating national landscape identity. Malaysia with great interest and potential with three main ethnic groups was selected as a case study. It is presumed that people with divers cultural backgrounds would have difference opinions about gardens. With the attention to the visual and artistic quality of gardens, an iconographic method dealing with both art and history was selected in this study. It concluded that garden iconography should be understood as a collection of stimuli that is open to perception, interpretation, and judgment. Consequently, four gardens among well …

Socio-Economic Revitalization Through Brownfield Reclamation, Corrin James Breeding

Masters Theses

Brownfields are defined as real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of hazardous substance, pollutant, or contaminant (epa.gov). Brownfield remediation is land rehabilitation.

There are many brownfield sites that exist around the world today. These locations are nuisances because of their effect on the environment. They can be eyesores, riddled with dilapidated structures and debris that put chemicals into the soil, affect local watersheds, become prime areas for violence and/or other activities viewed as unsafe, etc. The impact these areas have on the health of living organisms is a …

The Latest Homebond House Building Manual : A Critique, Joseph Little

Articles

The Homebond House Building Manual had the distinction of being called the ‘bible’ for many building during the boom. It was a commonly‐used reference book, even for many builders and architects who never built housing estates and therefore had little need of a Homebond guarantee. One might design a construction detail of a dwelling differently, but one did it with an awareness of what the manual showed. It gave the insurance scheme great credibility and standing. This architect remembers reluctantly getting involved with an external wall insulation self‐build project in rural Ireland in 2006 (far beyond his normal travel distance) …

[Re]Connection, Taylor Hahn

Masters Theses

In this thesis, I argue for a place where people can go to regain perspective, and to reevaluate their interactions, both with other people and their environment. This proposal explores ways in which architectural design creates a setting where the built environment is intrinsically connected to systems and forms of the natural environment. The design project consists of a facility in McLean, Virginia, just west of Washington, DC, on the southern bank of the Potomac River, for the temporary stay of people suffering from depression: who feel alienated in a world full of connections. Cases of depression are higher than …

Disappearing Vistas, Jessica Christine Bundy

Masters Theses

National parks have historically used long distance scenic views, known as vistas, to reveal iconic American landscapes to auto tourists. However, decades of budget constraints and inadequate management have prevented National Parks from maintaining vistas as originally intended. Many important vistas are disappearing due to encroaching vegetation. As a result, numerous complaints and concerns have been expressed by park visitors, especially within Great Smoky Mountains National Park. Vistas still play an intricate role in the visitor experience of national parks – an experience worth protecting. In an effort to conserve this experience, ecologically sustainable vistas must be established that are …

Implementing Building Information Modeling In Public Works Projects In Ireland, Barry Mcauley, Alan V. Hore, Roger West

Conference papers

The Irish State in recent years has suffered huge financial losses in the public works sector, which has now pushed the Irish Government to explore new ways of controlling cost. This background lead to the introduction of the Capital Works Management Framework in 2007 which aimed to support the certainty of outcome in terms of cost and quality, as well as improved risk management, through the implementation of fixed price contracts. In order to successfully compete within this framework it is recommended by the authors, that Irish Government moves towards the legal mandating of BIM. This can ensure a greater …

Estimating The Useful Life Of Buildings, Craig Langston

Craig Langston

Obsolescence is a phenomenon that is widely discussed in the literature, although rarely in relation to buildings. In this paper parallels are drawn between obsolescence, depreciation and discounting in order to develop a new method for predicting the impact of building obsolescence based on measurable context factors. These factors have physical, economic, functional, technological, social, legal and political characteristics. Useful life is defined as discounted physical life, where the rate of discount is determined from predicted future obsolescence. As part of the method, a new tool for determining the physical life of buildings is presented. Using an adaptive reuse paradigm …

Using Life Cycle Assessment Methods To Guide Architectural Decision-Making For Sustainable Prefabricated Modular Buildings, Jeremy Faludi, Michael Lepech, George Loisos

Dartmouth Scholarship

Within this work, life cycle assessment modeling is used to determine top design priorities and quantitatively inform sustainable design decision-making for a prefabricated modular building. A case-study life-cycle assessment was performed for a 5,000 ft² prefabricated commercial building constructed in San Francisco, California, and scenario analysis was run examining the life cycle environmental impacts of various energy and material design substitutions, and a structural design change. Results show that even for a highly energy-efficient modular building, the top design priority is still minimizing operational energy impacts, since this strongly dominates the building life cycle's environmental impacts. However, as an …

Green Infrastructure Resource Directory, New England Environmental Finance Center

Sustainable Communities Capacity Building

Green infrastructure is an approach for managing stormwater that uses vegetation and soils to capture and treat rainwater where it falls. Unlike single-purpose gray infrastructure, green infrastructure realizes multiple benefits at once, including flood mitigation, improved water and air quality, community beautification, provision of recreational opportunities, and energy and cost savings. This resource directory is intended to help communities design, implement, fund, and monitor green infrastructure practices and programs. It was compiled by the Environmental Finance Center Network through the Capacity Building for Sustainable Communities program funded by U.S. Department of Housing and Urban Development and U.S. Environmental Protection Agency. …

The project consists of two main components: the conservation plan and a companion paper. The …

Form-Based Codes, Design Guidelines And Placemaking: The Case Of Hayward, Ca., Cindy Ma

Master's Theses

Throughout history planning codes and standards have been used to regulate the built environment for health, power, order, and economic reasons. More recently, in the urban design and planning field, planning codes and standards have emerged to become tools in the process of “placemaking”. The concept of placemaking builds from the desire of humans to create places, not spaces, which are unique, attractive, identifiable, and memorable. It is a concept that is comprised of visual and social components, recognizing the need for both in the creation of successful places. In the field of urban design and planning, form-based codes (FBCs) …

Unlv Students To Build Zero Net Energy Home; Boom & Bust Report, Nevada Institute For Renewable Energy Commercialization (Nirec)

Nevada Newsflash

Design and build an approximately 800 square foot home that consumes zero net energy.

Those are the instructions for Team Las Vegas, after the University of Nevada, Las Vegas (UNLV) became one of only 20 schools worldwide to quality for the 2013 Solar Decathlon, sponsored by the U.S. Department of Energy’s National Renewable Energy Laboratory.

UNLV’s entry, Autonomy House, is marketed as an “age-in-place” home for an empty nester whose children have grown up. The 730-squarefoot home will use daylighting from windows, insulation and solar panels to produce more energy than it consumes. Additionally, it will filter rainwater for household …

Deep Play, Urban Space, Adolescent Place: A Multi-Sited Study Of The Effects Of Settings On Adolescent Risk/Reward Behavior, Benjamin A. Shirtcliff

University of New Orleans Theses and Dissertations

The extant literature on the play behavior of youth normalizes adolescent behavior in public space as transgressional, resistant, and in need of social control. The dissertation counters this trend by looking to see if physical qualities, peer effects, and neighborhood context of settings play a deeper role in youth behavior. The study documented urban context, peer effects, physical features, and play behavior across 21 urban settings in New Orleans. Unobtrusive observations employed a highly innovative technique based on YouTube videos and analyzed using hierarchical linear modeling. Coded observations of risk-taking and prosocial behavior demonstrated some stability in behavior amongst adolescents—“youth” …

Get Your Butt Off The Ground!: Consequences Of Cigarette Waste And Litter-Reducing Methods, Joyce Lee

Pomona Senior Theses

Cigarette butts are rapidly accumulating on our planet; trillions of them are discarded every year. In this paper, I examine why cigarette litter is a problem. I first discuss the biodegradability of filters and its scientific basis, including ways to enhance degradation rates by chemically manipulating filters. I also talk about the persistence of cigarette chemicals and their potential toxic effects on children and animals. I consider other social, economic, and environmental consequences of cigarette filters and chemicals. Furthermore, I discuss various solutions smokers and non-smokers alike have created to address the problem of cigarette litter; these methods come from …

Teaching Old Buildings New Tricks: Benefits Of Retrofitting Indianapolis Buildings With Green Roofs, Sarah Elizabeth Strobl

Undergraduate Honors Thesis Collection

Not your basic rooftop garden, green roofs contain growing media and are planted with various types of vegetation. Green roofs can be either intensive, with soil depths above 6 inches and increased size and attractiveness of vegetation, such as trees and shrubs, or extensive, with soil depths between 2-6 inches and low, moss or grass-like plants that require little care (Getter et al. 2009, Indianapolis DPW 2008, Obemdorfer et al. 2007, US DOE 2004).

Although green roofs are initially more expensive than traditional roofing techniques due to the cost of additional materials, the long-term cost savings are high and can …
