"Defining Job Titles And Career Paths In Bim", Malachy Mathews

Conference papers

Ireland is undergoing a digital transformation. Some industries particularly in the areas of travel and retail have been radically transformed. However many industries are facing their biggest challenge in their existence already weakened by the economic crisis and constrained by their legacy business, it will be difficult for them to adapt and embrace the new rules dictated by digital change. Irelands design and construction industry is on the cusp of a digital transformation with early adopters now deriving some benefits from a move to a building information modeling (BIM) process. Digital transformation cannot happen unless there are personnel with the …

Bim; Postgraduate Multidisciplinary Collaborative Education, Malachy Mathews

Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …

Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma

The Summer Undergraduate Research Fellowship (SURF) Symposium

Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …

Seismic Performance Comparison Of A Fixed-Base Versus A Base-Isolated Office Building, Nicholas Reidar Marrs

Master's Theses

The topic of this thesis is base isolation. The purpose of this thesis is to offer a relative understanding of the seismic performance enhancements that a typical 12-story steel office building can achieve through the implementation of base isolation technology. To reach this understanding, the structures of a fixed-base office building and a base-isolated office building of similar size and layout are designed, their seismic performance is compared, and a cost-benefit analysis is completed. The base isolation system that is utilized is composed of Triple Friction Pendulum (TFP) bearings.

The work of this thesis is divided into four phases. First, …

Survey Of Suitable Plants For Cal Poly's Green Wall, Katrina Burritt

Horticulture and Crop Science

Green wall technology is a growing industry in the United States and has been very successful for a several years throughout Europe. The objective of this survey was to study the success of several different species of plants on a vertical wall facing south at Cal Poly’s Horticultural Department Unit. At first the focus was aimed at using California native species, because it was thought that natives would be better acclimated to the exposure in this specific location. It became apparent that plants should not be selected for the wall based just on the fact that they are California natives. …

[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 …

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 …

Articles

This article is the third in a series looking at thermal upgrades to single-leaf walls of existing houses. The theme for this article was intended to be an analysis of various drylining options for brick and rubble-built walls of older properties. That will follow. The following events forced a change in focus.

Breaking The Mould 2 : An Analysis Of Single-Leaf Insulation Upgrades, Joseph Little

Articles

This article is the second in a series looking at thermal upgrades to single-leaf walls of existing houses. It compares a range of ways of upgrading masonry single-leaf walls, particularly the ubiquitous hollow block wall, and the impact of those decisions on moisture content, wind- and airtightness, cost and heating. Future articles will look at various drylining approaches for a range of walls including brick walls of various widths.

Breaking The Mould 1 : A Study Of Condensation In Single-Leaf Concrete Wall Upgrades, Joseph Little

Articles

This article is the first of a series looking at upgrade options and issues associated with single-leaf walls of existing houses. This article will focus on insulated drylined concrete block walls of the ubiquitous housing estate house. This will include the findings of software that dynamically models moisture movement through the wall over several years. The article following this will look at a range of options for replacing existing drylining or installing drylining where it never was before, be that for a solid block wall of a 1950s house or a solid brick wall of an 1850s house.

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 …

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 …
