Wind Loading On Trees Integrated With A Building Envelope, Aly Mousaad Aly, Alberto Zasso, Girma Bitsuamlak, Alberto Nicola Longarini, Arindam Gam Chowdhury

Faculty Publications

With the sustainability movement, vegetated building envelopes are gaining more popularity. This requires special wind effect investigations, both from sustainability and resiliency perspectives. The current paper focuses on wind load estimation on small- and full-scale trees used as part of green roofs and balconies. Small-scale wind load assessment was carried out using wind tunnel testing in a global-effect study to understand the interference effects from surrounding structures. Full-scale trees were investigated at a large open-jet facility in a local-effect study to investigate the wind-tree interaction. The effect of Reynolds number combined with shape change on the overall loads measured at …

Sensitivity Studies Of A Low Temperature Low Approach Direct Cooling Tower For Building Radiant Cooling Systems, Medhi Nasrabadi, Donal Finn, Ben Costelloe

Conference Papers

Recent interest in cooling towers as a mechanism for producing chilled water, together with the evolution of radiant cooling, have prompted a review of evaporative cooling in temperate maritime climates. The thermal efficiency of such systems is a key parameter, as a measure of the degree to which the system has succeeded in exploiting the cooling potential of the ambient air. The feasibility of this concept depends largely however, on achieving low approach water temperatures within an appropriate cooling tower, at acceptable levels of energy performance. Previous experimental work for a full scale evaporative cooling system has shown that it …

Gothic Architecture, Geometry, And The Aesthetics Of Transcendence, Robert Bork

UNIversitas: Journal of Research, Scholarship, and Creative Activity

In these remarks I will discuss Gothic architecture, geometry, and what I call the aesthetics of transcendence. I’ll focus mainly on the design of great buildings like Strasbourg Cathedral, whose spire is the tallest surviving work of the Middle Ages, a 466-foot symphony of intricately carved stone. I also want to talk about how I came to study and admire this material, starting out from a curiously backdoor approach involving the sciences. Ultimately, therefore, I will argue that Gothic architecture can be fruitfully compared to a variety of things, such as fractals, heavy metal guitar music, and dinosaurs. These are …

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 …

Theatre For A New Theater: A Play On Architecture, Alex Coulombe

Renée Crown University Honors Thesis Projects - All

The project entails transforming a former military fort into a theater. The scopic parameters native to both fort and theater can provide a field of operation for an architecture that simultaneously mobilizes and exposes the machinery of spectacle. In tandem, amplifying and distorting existing conditions of the fort and repurposing them for a theatrical program can provide catalytic parameters for design that are typically absent when designing from a clean slate.

Urban Fabrication: The Architectural Heightening Of The Urban Tactile Sensibility A Fiber Arts Fabrication & Exhibition Center In Dublin, Ireland, Elizabeth Fallon

Renée Crown University Honors Thesis Projects - All

The discipline of fiber arts has been in existence since the beginning of civilization to produce both functional equipment as well as aesthetically driven art pieces. The craft, at times highly specialized, often produces elements at the scale of the human body, due to the personal level by which fiber artifacts are produced. The making of artifacts and implementation of fiber art strategies have simultaneous cultural, environmental, formal, and gender-related relationships and implications. The design, construction and experience of buildings and inhabitable space at all scales can benefit from these relationships.

It is the contention of this thesis to merge …

Increasing Stimulation | Decreasing Progression: The Built Environment’S Impact On Alzheimer’S And Dementia, Tracy Chin

Renée Crown University Honors Thesis Projects - All

With people living longer lives, the population of elderly is increasing at significant rates. Currently 5.3 million suffer from Alzheimer’s in America and 35 million people worldwide. The disease is one that deteriorates brain cells which in turn affects everyday thinking, behavioral problems, and results in a reduced mastery of one’s environment. The current typology is one that has been designed along the same premises of medical institutions and hospitals. The configuration results in narrow corridors and confined, unlit spaces that lead to disorientation and fear—exacerbating both physical and mental symptoms of the disease.

In addition to memory, sensory losses …

[Dis]Lodge; A Transformation Of The Ski Lodge In Response To Function And Site, Jacob E. Schneck

Renée Crown University Honors Thesis Projects - All

Over the past century skiing has experienced remarkable growth in popularity, equipment and technique. From 1946 to the present the number of ski resorts in North America with operating lifts has grown from 15 to over 600. During this time skiing has developed from a means of winter travel into a sport that combines paramilitary precision and control with leisure. Driven by economic interests and the superficial imitation of European alpine architecture the contemporary ski lodge model has failed to meaningfully address these changes and has failed to address function and context in terms of both its formal organization and …

Implementation Of Building Information Modeling In Architectural Firms In India, Aakanksha Luthra

Purdue Polytechnic Directed Projects

Building Information Modeling (BIM) is an integrated process of generating and managing a building by exploring a digital model before the actual project is constructed and later during its construction, facility operation and maintenance. BIM has been adopted by construction contractors and architects in United States (US) and United Kingdom (UK) to improve the planning and management of construction projects. On the contrary, Indian contractors seem to have made a head-start by using BIM in their projects, but the architects in the nation have still not embraced this new thinking and technology as a part of their way of working. …

Breaking The Mould 4 : Condensation Risk Analysis – The Standards And The Issues, Joseph Little

Articles

The ‘Breaking the Mould’ series of articles was written to explore the range of issues associated with upgrading single leaf walls with a focus on occupant and building health as much as energy, just as the Home Energy Saving Scheme was launched. A year on from the first article the need for greater understanding and clear guidance for the Industry is greater than ever. This is because the Government’s ‘Energy Demand Reduction Target’ (EDRT), under the 2006 EU ‘Energy Services Directive’, is bringing energy utilities (e.g. ESB, Bord Gáis) into the refurbishment market.

Following Industry's Leed : Municipal Adoption Of Private Green Building Standards, Sarah B. Schindler

Faculty Publications

Local governments are beginning to require new, privately constructed and funded buildings to be “green” buildings. Instead of creating their own, locally-derived definitions of green buildings, many municipalities are adopting an existing private standard created by members of the building industry: LEED (Leadership in Energy and Environmental Design). This Article explains and assesses the privately promulgated LEED standards. It argues that the translation of LEED standards, which were intended to be voluntary, into law raises several theoretical and practical problems. Specifically, private green building ordinances that rely on LEED do not ensure a reduction in the negative local environmental impacts …

Frame It - Thoughts On Education, Reducing Carbon And Vapour, Joseph Little, Robbie Cousins

Articles

Joseph Little believes timber frame can be the backbone of a new generation of low-carbon, energy-efficient housing, and be used as an intelligent response to Climate Change and fuel prices. But he tells Robbie Cousins that timber frame manufacturers, suppliers and architects need to gear-up and work more closely together if the true potential of this vision is to be realised.

Joseph Little’s chief bugbear is poor construction standards & details on site and the core of this issue is how the knowledge set of architects and builders and how standards are controlled. The seeds of this idea may have …

Thermal Performance Of Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Conference Papers

Meteorological enthalpy analysis of temperate and maritime climates above 45˚N suggests that the water-side evaporative cooling technique has considerable unrealised potential with contemporary "high temperature" building cooling systems - such as chilled ceilings. As low approach conditions are the key to exploiting the cooling potential of the ambient air, thermal performance at such conditions needs to be investigated. To address the research issues a test rig, based on an open cooling tower and plate heat exchanger and designed to maximise evaporative cooling potential, has been constructed at DIT. A combination of experimental measurement and analysis is used in the investigations. …

The Earth All Around Us: Selected Building Stone In Lincoln, Nebraska. A Walking Tour, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Stone has been a primary building material for millennia. Cities, therefore, are treasure troves of earth materials. A wide variety of stones from many places are used for walls, as foundations to support entire buildings, as trim, and more recently as cladding (facing, an overlay). The Earth science teacher can find, in the limited space of an urban environment, a superb collection of stones with which to introduce students to these materials. The surfaces of stones on the outsides of buildings illustrate the durability and the vulnerability of each kind of stone to the local climate. And the history of …

Construct Ireland - Lime-Hemp - A Potential Solution To A Concrete Problem, Joseph Little

Articles

This article is intended to act as an exploration and provocation. Why do we build the way we do, what effect does that have? Could we for instance, design and specify buildings that actually benefit the Environment rather than burden and pollute it as currently. Is it possible that the construction of a house could absorb CO₂ thereby transforming new housing estates or apartment buildings into giant absorbers of carbon dioxide? Imagine Ireland being able to count commercial constructions or new housing among its ‘carbon sinks’, in place of Siberian forests or the carbon credits that the Government will …

Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

Recent developments in enhancing heat transfer in cooling towers, together with the success of chilled ceilings, have prompted a review of the evaporative cooling technique. in temperate maritime climates. The thermal efficiency of such systems is a key parameter, as a measure of the degree to which the system has succeeded in exploiting the cooling potential of the ambient air. This paper presents the results of experimental research into the thermal efficiency of a water-side open indirect evaporative cooling test rig designed to achieve low (1-4 K) approach conditions. Secondary efficiencies in the range 0.24-0.76 have been achieved.
