Art On Water: Art That Revitalizes Insular Communities Facing Depopulation And Economic Decline, Kentaro Yagi

NAKHARA (Journal of Environmental Design and Planning)

The Inland Sea of Japan, once a flourishing cultural and economic artery, is now struggling with depopulation and economic decline. Traditionally, this area has been popular for public and privateart projects. Recent large-scale art projects and exhibitions on Naoshima Island and Inujima Island explored the possibilities of art in a public context. Site-specific artworks in collaboration with the local community have attracted visitors and brought about a favorable impact. Along with the rich historic and natural resources of the Inland Sea area, emerging art projects in various islands have started to revitalize the insular communities within.

Building America Research Benchmark Definition: Updated December 2009, R. Hendron, C. Engebrecht

Publications (SD)

To track progress toward aggressive multi-year, whole-house energy savings goals of 40%–70% and on-site power production of up to 30%, the U.S. Department of Energy (DOE) Residential Buildings Program and the National Renewable Energy Laboratory (NREL) developed the Building America (BA) Research Benchmark in consultation with the Building America industry teams. The Benchmark is generally consistent with mid-1990s standard practice, as reflected in the Home Energy Rating System (HERS) Technical Guidelines (RESNET 2002), with additional definitions that allow the analyst to evaluate all residential end uses, an extension of the traditional HERS rating approach that focuses on space conditioning and …

Optimum Absorption And Aperture Parameters For Realistic Coupled Volume Spaces Determined From Computational Analysis And Subjective Testing Results, David T. Bradley, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

This project utilizes computational modeling to study the effects of varying two architectural parameters, absorption ratio and aperture size, in a realistic coupled volume concert hall. Coupled volumes have been shown to exhibit non-exponential sound energy decay profiles, referred to as double slope effect. A number of objective metrics (T30/T15, LDT/T10, decay ratio, and ΔL) have been used to quantify the double slope effect of the profiles generated in the virtual hall. T30/T15 and LDT/T10 showed similar trends across all hall configurations, indicating decreasing double slope effect with increasing coupled volume absorption ratio for each aperture size, and producing highest …

Durham School of Architectural Engineering and Construction: Faculty Publications

This study investigated the effects of noise from building mechanical systems with tonal components on human task performance and perception. Six different noise conditions based on in-situ measurements were reproduced in an office-like setting; all were set to approximately the same sound level (47 dBA) but could have one particular tonal frequency (120 Hz, 235 Hz, or 595 Hz) at one of two tonal prominence ratios (5 or 9). Thirty participants were asked to complete typing, grammatical reasoning, and math tasks plus subjective questionnaires, while being exposed for approximately 1 hour to each noise condition. Results show that the noise …

Computational Modeling Of Effects Of Alloying Elements On Elastic Coefficients, Z. K. Liu, H. Zhang, S. Ganeshan, Y. Wang, S. N. Mathaudhu

Durham School of Architectural Engineering and Construction: Faculty Publications

Models for composition and temperature dependencies of single-crystal elastic stiffness coefficients are developed and applied to the Al₁₂Mg₁₇ and hexagonal closed-packed solution phases in the Mg–Al system based on data from first-principles calculations. In combination with models for multi-phases, the bulk, shear, and Young’s moduli of Mg–Al alloys are predicted and compared with available experimental data in the literature. It is noted that both phase transition and grain boundary sliding may play important roles in the elastic coefficients as a function of temperature.

Durham School of Architectural Engineering and Construction: Faculty Publications

The goal of this study was to investigate the effects of noise from building mechanical systems with time-varying fluctuations on human task performance and perception, and to determine how well current indoor noise rating methods account for this performance and perception. Six different noise conditions with varying degrees of time-varying fluctuations, many focused in the low frequency rumble region, were reproduced in an office-like setting. Thirty participants were asked to complete typing, grammatical reasoning, and math tasks plus subjective questionnaires, while being exposed for approximately one hour to each noise condition. Results show that the noise conditions with higher sound …

Concrete Slender Wall Design – Back To The Future, John W. Lawson, James Lai

Architectural Engineering

Slender concrete walls incorporated into tilt-up construction
over the past 60 years have performed remarkably well under
out-of-plane wind and seismic loads. While issues associated
with seismic wall anchorage gave this form of construction a
black-eye in the early days, the concrete walls themselves
have always performed very well even as far back as their
first use in the early 1900s. Yet the height-to-thickness
limitations in 1985 and earlier model building codes were
proved irrational and were removed. We as engineers expect
building codes to evolve and advance the state of the art with
each successive edition. The latest edition …

Re-Designing The 'Great Australian Dream': Creating A More Sustainable Housing Future, Eko Pam

Theses : Honours

Sustainable design is a buzzword in the field of architecture, yet very few houses built in Western Australia last year had an environmentally friendly focus. Through much debate and research, designers now have a thorough understanding of the environmental impact ofhousing (Kibert, 2005; Roaf, 2001; Yeang, 1995). The result is that architects worldwide are now offering a more sustainable housing model. These houses are expensive and look very different to the popular project homes. Despite this environmental awareness, the homes Western Australians build appear to be growing larger, with little regard for their future sustainability. There is reluctance among Australians …

Assessment Formats: Student Preferences And Perceptions, Mairéad Seymour, Shannon Chance

Articles

This paper provides a student perspective on the variety of forms of design critique available to educators. In architecture and landscape architecture, the design jury remains the dominant format for providing feedback to students. In recent years this format has come under scrutiny and its effectiveness called into question. However, little research has been done into the variety of alternative or supplemental formats available to educators. This paper explores an array of techniques that the authors have employed in design studio courses (which include techniques suggested by students in Webster’s 2007 article in the Journal of Architectural Education). These include …

Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

Predicting the insertion loss of an opening backed with an enclosed space is important for building noise control. Recent research in sound transmission through apertures of finite depth in infinite rigid baffles has included the effects of propagating and evanescent modes within the aperture in order to extend models to higher frequencies. The present study extends the model to the case of the aperture backed by a cavity as opposed to sound radiating into half-space. The role of coupling between the aperture modes, radiation modes, and cavity modes in the transmission was investigated. The results were compared to those of …
