Saving Software And Using Emulation To Reproduce Computationally Dependent Research Results, Euan Cochrane, Limor Peer, Ethan Gates, Seth Anderson Dec 2019

Saving Software And Using Emulation To Reproduce Computationally Dependent Research Results, Euan Cochrane, Limor Peer, Ethan Gates, Seth Anderson

Yale Day of Data

Using digital data necessarily involves software. How do institutions think about software in the context of the long-term usability of their data assets? How do they address usability challenges uniquely posed by software such as, license restrictions, legacy software, code rot, and dependencies? These questions are germane to the agenda set forth by the FAIR principles. At Yale University, a team in the Library is looking into the application of a novel approach to emulation as a potential solution. In this presentation, we will outline the work of the Emulation as a Service Infrastructure (EaaSI) program, discuss our plans for ...

Centres Of Excellence And Roadmaps For Digital Transition: Lessons For Ireland’S Construction Industry, Barry Mcauley, Alan Hore, Roger West

Conference papers

Like most sectors in today’s working world, construction businesses are challenged to work in an increasingly digitised world with sophisticated demands from intelligent clients. So much has been written about the inefficiencies of the construction industry, its fragmentation, lack of collaboration, low margins, adversarial pricing, poor productivity, financial fragility, lack of research and development, poor industry image and relatively weak use of digital solutions. The Irish government recognises the importance of digital innovation to address many of the challenges the construction industry faces. With recent high profile reports of escalating spend on signature public sector projects and weak productivity ...


An Investigation Into Current Procurement Strategies That Promote Collaboration Through Early Contractor Involvement With Regards To Their Suitability For Irish Public Work Projects, Barry Mcauley, Frederic Lefebvre Sep 2019

An Investigation Into Current Procurement Strategies That Promote Collaboration Through Early Contractor Involvement With Regards To Their Suitability For Irish Public Work Projects, Barry Mcauley, Frederic Lefebvre

Conference papers

Previous research has established that multi-disciplinary collaboration will benefit a construction project throughout its lifecycle. While Lean Construction, Building Information Modelling (BIM), and Integrated Project Delivery (IPD) can all be viewed as separate processes which add independent value to a project, they are more effective when used in partnership with each other. In order to ensure the high levels of collaboration expected for these processes to work in unison, the early involvement of the Contractor is paramount. Early contractor involvement within the design process can ensure a more focused integrated project team, improvement of both constructability and cost certainty, as ...


Improving The Sustainability Of The Built Environment By Training Its Workforce In More Efficient And Greener Ways Of Designing And Constructing Through The Horizon2020 Bimcert Project, Barry Mcauley, Avril Behan Sep 2019

Improving The Sustainability Of The Built Environment By Training Its Workforce In More Efficient And Greener Ways Of Designing And Constructing Through The Horizon2020 Bimcert Project, Barry Mcauley, Avril Behan

Conference papers

The construction industry consumes up to 50% of mineral resources excavated from nature, generates about 33% of CO2 present in the atmosphere and is responsible for 40% of total global energy through both construction and operation of buildings. The realisation that current pervasive construction practices now face globalization, sustainability, and environmental concerns, as well as ever-changing legislation requirements and new skills needed for the information age has resulted in technologies such as Building Information Modelling (BIM) becoming a key enabler in navigating these barriers. To assist in overcoming these barriers, a number of funding initiatives have been put in place ...


Bim In Ireland 2019: A Study Of Bim Maturity And Diffusion In Ireland, Barry Mcauley, Alan Hore, Roger West Sep 2019

Bim In Ireland 2019: A Study Of Bim Maturity And Diffusion In Ireland, Barry Mcauley, Alan Hore, Roger West

Conference papers

In 2017, the BIM Innovation Capability Programme team applied five macro BIM maturity conceptual models to capture the capability of the Irish construction industry and assess its BIM maturity. The results found that while Ireland is mature for modelling processes, it is less developed with regards to collaboration processes and policies. Ireland also ranked poorly when it came to regulatory frameworks, measurements and benchmarks compared to a number of countries which also applied the same conceptual models. At the time, the findings highlighted that Ireland’s diffusion dynamic was middle out, meaning that larger organisations or industry associations were pushing ...


From Roadmap To Implementation: Lessons For Ireland’S Digital Construction Programme, Barry Mcauley, Alan Hore, Roger West Sep 2019

From Roadmap To Implementation: Lessons For Ireland’S Digital Construction Programme, Barry Mcauley, Alan Hore, Roger West

Conference papers

As part of their Future of Construction initiative in 2018 the World Economic Forum published an action plan to accelerate Building Information Modelling adoption. The WEF report highlighted actions that companies, industry organisations and governments are advised to implement to accelerate BIM adoption and better capitalise on delivering better project outcomes. According the authors of the report BIM is seen as the centrepiece of the construction industry’s digital transformation, however they acknowledged that BIM adoption globally remain slow. Anecdotal experience would suggest that BIM usage in Ireland is also very low and that a similar initiative or an adaptation ...


Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang Sep 2019

Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang

Publications and Research

The current methods for the prediction of the heat flow through building entrance doors have been used for years while involved with a certain degree of uncertainty. This paper describes an experimental method that accurately quantified such heat flow. The experiment monitored local environmental parameters in a college building on a cold winter day. The results of the experiment demonstrated that the experimental method is viable to accurately estimate the heat flow throughout the entrance doors and the presence of a vestibule moderated heat losses from the conditioned area. The results will be used for validating the existing methods.


Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand Sep 2019

Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand

Publications and Research

A spray PDEC system has been relatively less considered than other passive cooling strategies as one of the viable low-energy solutions in the cooling of buildings while having a great potential in energy savings. This study is intended to evaluate the capability of a spray PDEC system for space cooling. It comprises four simulation scenarios to see the system response and influence of indoor thermal environment when a spray PDEC system is adopted as a primary cooling system in two different climates. The simulation results show that a spray PDEC system causes a substantial variation in the indoor thermal environment ...


2019 Btes Conference Program Integration + Innovation, Caryn Brause, Peggi Clouston, Naomi Darling Jun 2019

2019 Btes Conference Program Integration + Innovation, Caryn Brause, Peggi Clouston, Naomi Darling

Building Technology Educator's Society

Following on the alliterative themes of recent BTES conferences, we have selected Integration and Innovation as the theme for the 2019 gathering. Innovation can begin with conjecture, with a searching for more effective solutions, or with an application to currently unknown or unarticulated needs. Innovation scholarship examines the personal intellectual habits that support new ideas, such as openness and exploratory behavior, as well as the circumstances behind the places in which creativity flourishes, such as support for cross-disciplinary fertilization and access to resources. The 2019 BTES conference will explore the role of technology education and curriculum in cultivating these intellectual ...


Development Of A Framework To Support The Effective Adoption Of Bim In The Public Sector: Lessons For Ireland, Shiyao Kuang, Alan Hore, Barry Mcauley, Roger West Jun 2019

Development Of A Framework To Support The Effective Adoption Of Bim In The Public Sector: Lessons For Ireland, Shiyao Kuang, Alan Hore, Barry Mcauley, Roger West

Conference papers

Building Information Modelling (BIM) has been formally adopted by many countries with the promise of creating greater economic, social and sustainability benefits. Several authors and institutions have presented alternative BIM policies and tactics which have been adopted by developed countries. However, there is evidence to indicate that BIM adoption theories are not well established and, in particular, the linkage between BIM public sector adoption strategy outcomes and their contribution to achieving Government policy objectives are underdeveloped. This paper will present the outcome of the first phase of a systematic literature review of published studies (including journal papers and noteworthy international ...


Bridging The Gap Between Architecture And Engineering: A Transdisciplinary Model For A Resilient Built Environment, Michelle Laboy, Annalisa Onnis-Hayden Jun 2019

Bridging The Gap Between Architecture And Engineering: A Transdisciplinary Model For A Resilient Built Environment, Michelle Laboy, Annalisa Onnis-Hayden

Building Technology Educator's Society

As the focus of environmental engineering increasingly shifts to landscape-based, decentralized solutions to energy and water; and as architecture increasingly shifts its attention to resilience, ecological connectivity and independence from centralized infrastructure, these two disciplines find themselves closer in scale than before. This paper presents a collaborative project between upper level architecture and environmental engineering students focused on the design of sustainable and integrated water systems. Critical features of transdisciplinarity included: the engagement of stakeholders in the process at multiple moments; the speculative nature of working on very distant futures, the multi-scalar requirements of the collaboration, and the expectation of ...


Intuition Before Integers: Integrating Building Technology Into The Design Studio, James Leach, Kristin Nelson Jun 2019

Intuition Before Integers: Integrating Building Technology Into The Design Studio, James Leach, Kristin Nelson

Building Technology Educator's Society

The studio methodology, used almost universally to teach architectural design in the US, embraces speculative investigation and hands-on learning, offering unparalleled opportunities for integrated thinking and open-ended inquiry. Building technology courses, in contrast, tend to be taught in more constrained, and more passive modes - lecture classes, sometimes accompanied by a laboratory or including a project or two. As instructors of both design studios and building technology courses, we have found it difficult to generate the level of engagement and enthusiasm, or achieve the depth of inquiry, in the technology classroom that is common in the design studio. Moreover, we find ...


The Corner: Tectonic Intersections Of The Architectural Environment, Chad Schwartz, Jaasiel Duarte-Terrazas,, Nataani Garnenez Jun 2019

The Corner: Tectonic Intersections Of The Architectural Environment, Chad Schwartz, Jaasiel Duarte-Terrazas,, Nataani Garnenez

Building Technology Educator's Society

Architectural corners serve as nodes of constructional shifting, of structural logistics, of environmental control emphasis, of spatial experience, and of aesthetic considerations and it is in these particular building intersections that our greatest architects have exceled. Despite the importance of the corner, most architectural software introduces generalizations into design work that all but assures improper understanding of a building’s corners, especially for students and those novice to the profession. The transformations undertaken in the computer rarely reflect the strategies used to create physical, occupiable space. For instance, when working in building information modeling software, walls intersect via “butt” or ...

Truss-Ting History, Chad Dennis, Joshua Friedman

Building Technology Educator's Society

Building performance in this case being evaluated by traditional means, such as energy use over time, in addition to qualitative questions of space, history, pedagogy etc. Another term explicit in this project is that of “future use” by which we build on typical modes of site analysis in addition to the growing body of research developed through building scientists, we ask how building systems can be used to accommodate a variety of program while simultaneously maintaining a strong connection to place. Through the use of a hybrid system of glulam trusses and CLT panels to repurpose an existing historic pumphouse ...


Design/Lift: An Extra Concrete Beam In A Park, Federico Garcia Lammers Jun 2019

Design/Lift: An Extra Concrete Beam In A Park, Federico Garcia Lammers

Building Technology Educator's Society

According to the Department of Transportation, a commercial truck can drive at a maximum speed of sixty miles per-hour while carrying a sixty-foot-long precast concrete beam on a state highway. The beam in question is headed to a town of 1,800 people to be installed as part of a student-driven, faculty led Public Works project in Webster, South Dakota. Design/Lift focuses on the choreography of lifting and positioning a large piece of concrete on a public site. The beam sits in a yard, unapproved to span highway bridges, but potentially ready to engage the public in unexpected ways ...


Automated Comprehensiveness: Sectional Practices And The Misuse Of Revit, Jessica Garcia Fritz Jun 2019

Automated Comprehensiveness: Sectional Practices And The Misuse Of Revit, Jessica Garcia Fritz

Building Technology Educator's Society

All architectural drawings leave gaps in information. Drawing sets leave the impression that a combination of drawing types is comprehensive, that more information is better, but gaps always exist. In generating architecture, these gaps serve as opportunities for ambiguity, speculation, and exploration. The introduction of BIM in the late twentieth century and its more ubiquitous application in Autodesk’s 2004 release of Revit, challenged these previous notions of orthographic comprehensiveness as many images could be output from a single digital model. As representational types, plans, sections, elevations, and details did not disappear. Yet, the historic and conceptual practice for generating ...


Timber 4.0: Open Source Systems As A Democratic Tool For Designing And Building, Ulrich Dangel Jun 2019

Timber 4.0: Open Source Systems As A Democratic Tool For Designing And Building, Ulrich Dangel

Building Technology Educator's Society

Architecture, as it exists today, is deeply rooted in perceptions that were established during the Renaissance, which credited the architect as the sole author of creative thinking processes and the resultant design ideas. Since then, the architectural profession has desired to develop new and innovative ways of building, often without being bound by traditions, the environment, or any other constraints and limitations. This approach has frequently failed to address the needs and concerns of many. As a result, architects have not been successful in imparting significant social change that is valuable to large portions of the population. In contrast, however ...


Structures For Relief & Resiliency: Enhancing Creative Applications Of Technical Acumen Through Constrained Conditions, Rob Whitehead Jun 2019

Structures For Relief & Resiliency: Enhancing Creative Applications Of Technical Acumen Through Constrained Conditions, Rob Whitehead

Building Technology Educator's Society

The design of places, objects, and experiential operations are of great importance to the relief, recovery and rebuilding efforts that affect millions of people each year. Proactively designing for these scenarios requires a more than just sensitivity to the vexing nature of the people and their problems. The inter-disciplinary teams that assist in these efforts must be able to translate these activities into solutions that have insights into the structural, material, and construction considerations. Without these qualities, the tangible, useful, and deployable solutions could be marginalized until they become the lowest common denominator of design solutions.

The value of design ...


Big Glue! Testing The Scalability Of Adhesives In Architecture And Design, Emily White, Erik Sapper Jun 2019

Big Glue! Testing The Scalability Of Adhesives In Architecture And Design, Emily White, Erik Sapper

Building Technology Educator's Society

This paper documents the questions, methods and outcomes of “Big Glue,” a research collaboration among students and faculty from Cal Poly, San Luis Obispo’s chemistry and architecture departments that explores the potentials of structural adhesives in architecture and design. The project asks how adhesives can be more broadly used as work increases in size from the scale of models to full-scale construction.

Our focus is on aluminum structures. We looked at existing adhesive use in construction and in the automotive industry, where adhesives are increasingly used on aluminum and aluminum composites to reduce weight and consequently increase fuel efficiencies ...


Energy Use Intensity As A Driver For Building-Envelope Design, Scott Murray Jun 2019

Energy Use Intensity As A Driver For Building-Envelope Design, Scott Murray

Building Technology Educator's Society

As the principal interface between interior and exterior environments, the building envelope plays a primary role in the success or failure of a building’s response to its climate. The design and subsequent performance of building-envelope systems can have significant impacts on the overall energy performance of a building during its lifespan. Design decisions about window-to-wall ratios, the placement and orientation of glazing and shading devices, the components of opaque wall assemblies, and the selection of facade materials, products, and systems each contribute to a building envelope’s performance. To design high-performance enclosures, architects must understand the relationship between these ...


Water And Land In Flux: Pedagogy For Design Innovations That Inhabit Water, Niloufar Emami Jun 2019

Water And Land In Flux: Pedagogy For Design Innovations That Inhabit Water, Niloufar Emami

Building Technology Educator's Society

The Float’n’rise Design Studio encourages a paradigm shift in design by speculating how a partially submerged building can be designed along the Southern Louisiana coast. As the erosion and submersion of terra firma continues, what might the future of a community’s existence look like? If the fact that once-inhabitable ground slowly submerges is assumed, why not construct buildings designed to float on water in the first place? Instead of holding firm to past ground/water conditions, and only raising buildings according to the hundred-year flood level principle, why not embrace a relationship with water as a new ...

Revision Of The Archicad Manual For Cm 115, Emma Wagner

Construction Management

Each CM 115: Fundamentals of Construction Management section contains a quarter long project, the goal of which is to familiarize the students with a modeling software. More so, the goal of the project is to introduce them to a set of construction documents- how to get started, what is included, what they need to pay attention to as a construction manager, and most importantly, to implement what they learn from their written coursework completed during class. This manual was written to help students complete this assignment to the best of their ability, producing a piece of work that shows they ...


Documentation Of Concrete Slabs Prior To Pours, Peter D. Riley Jun 2019

Documentation Of Concrete Slabs Prior To Pours, Peter D. Riley

Construction Management

Concrete slabs in multi-level commercial building projects contain many components that become no longer visible once concrete has been poured. As building designs advance and continue to locate components in concrete, it is important to document what these slabs contain in order to verify accurate craftsmanship and allow for improved future construction workflows and building modernizations. This paper explores current industry needs for proficient documentation as well as practices to achieve this. A case study was conducted, testing four devices that analyzed feasibility factors for realistic implementation by a contractor such as cost, interoperability, and level of skill required for ...

The focus of the study measures the density of the bamboo species Guadua angustifolia and the Panama hat plant Carludovica palmata on the island while noting a comprehensive compilation of the techniques and materials used in the building process. Using a mix of plots and transects, a comparison of harvested material to remaining material ...


What Is A Bim Design Model?, James Peters, Malachy Mathews Jan 2019

What Is A Bim Design Model?, James Peters, Malachy Mathews

Conference papers

The recent report into Building Information Management or BIM, by construction law experts May Winfield and Sarah Rock entitled “Winfield Rock Report” [1] gives reason to state that the UK architectural, engineering and construction industry or AEC, is hindered by the absence of a clear definition of Level 2 BIM. The ISO 19650-2 standard published in 2019, is based upon PAS1192-2:2013. The intent of ISO 19650-2 is to provide a road map to facilitate the standardisation of BIM process in a uniformed fashion. A key pillar of ISO 19650 is the “information cycle” and central to this is a ...
