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 ...


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 ...

Steel Structures That Breathe: Two Extensively Glazed Buildings That Integrate Natural Ventilation Within Structural Members, Patrick Charles Jun 2019

Steel Structures That Breathe: Two Extensively Glazed Buildings That Integrate Natural Ventilation Within Structural Members, Patrick Charles

Building Technology Educator's Society

The paper is a case study of two extensively-glazed steel- framed buildings, Jean Prouvé’s 1957 temporary school in Villejuif, France, and, Müller Verdan Architekten’s 2006 Sporthalle “Gotthelf” in Thun, Switzerland, that integrate natural ventilation within the building structure itself.

Practically, this unique approach enables the designers to provide usually mutually exclusive features, large glass formats and natural ventilation, without incurring the various penalties associated with operating such very heavy elements.

Conceptually, the idea of integrating the ventilation function within structural members goes against the standard orthodoxy consisting of the separation of enclosure systems from skeletal structural systems. This ...

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 ...


Trans-Disciplinary Detail In Mass Timber, David Kennedy Jun 2019

Trans-Disciplinary Detail In Mass Timber, David Kennedy

Building Technology Educator's Society

In Towards a New Architecture, Le Corbusier claims that the field of engineering, through its adherence to the noble fields of Economy and Mathematics, has surpassed the field of architecture in the pursuit of harmonious, meaningful structures. He does not suggest that architects partner with engineers; he only implores architects to cop-opt engineers’ ethic to leverage their own field from its current state of “retrogression”. Gaining expertise then obviates collaboration. Following this, Corbusier laments the glacial unfolding of architecture through incremental developments in structure and ornament, finding impetus for his cross-disciplinary foray in the previous five decades of material development ...

Material Design Integration, Roger Hubeli

Building Technology Educator's Society

The goal of an integrative building design studio is for students to develop and prove the capacity to integrate different technical and possibly legal and financial considerations into their architectural projects. In this context, it is most important for the students to learn how to maintain a clear conceptual strategy that can serve as a ‘pièce de résistance’ against the multitude of different pressures, providing a larger framework for design decisions. This presentation discusses a series of projects where this ‘pièce de résistance’ was based on the design potentials of advanced pre-cast concrete construction. Tectonic concerns, with a focus on ...


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 ...

Lost circulation costs are a significant expense in drilling oil and gas wells. Drilling anywhere in the Rumaila field, one the world's largest oilfields, requires penetrating the Dammam formation, which is notorious for lost circulation issues and thus a great source of information on lost circulation events. This paper presents a new, more precise model to predict lost circulation volumes, equivalent circulation density (ECD), and rate of penetration (ROP) in the Dammam formation. A larger data set, more systematic statistical approach, and a machine-learning algorithm have produced statistical models that give a better prediction of the lost circulation volumes ...
