Preservation Sustainability Modernism: The Qualitative Analysis Of Valuing Modern Architecture Through Preservation And Sustainability, Portland State University. School Of Architecture

Research-Based Design Initiative

As sustainability becomes increasingly important, it has transformed design, construction, and operation of new buildings. Preservation has become a common sustainability strategy; however, it is much easier to argue the historical value of a hundred year old wood-framed house than a modern glass structure. Many buildings constructed with modernist ideals have more currently become a topic of debate for sustainable preservation. The tension stems between preserving embodied energy of existing buildings and reducing the operational energy with new construction. Originating from the counteracting beliefs in authenticity and modifications, the current need for better energy performance is best improved by integrating …

Optimizing Efficiencies In Multi-Performance Upgrades To Unreinforced Masonry (Urm} Buildings, Julie Mcevoy Baines

Research-Based Design Initiative

In 2001, the City of Portland identified over 1,900 URM's, many of which have never been seismically upgraded. These structures will pose a serious risk to occupants both during and after a seismic event. In this collection of historic structures live and work thousands of families, school children, and professionals. Additionally, due to their lack of wall insulation and outdated mechanical systems, these URM buildings tend to perform poorly in terms of their energy use. It is important to understand why energy upgrades to our existing building stock is necessary. Buildings account for 40 percent of the emissions of carbon …

Barriers In The Implementation Of Cross-Laminated Timber As A Sustainable Alternative Structural System In Multi-Family Multi-Story Housing, Portland State University. School Of Architecture

Research-Based Design Initiative

Cross-Laminated Timber (CLT) was first developed in the early 1990s in Austria and Germany and has been gaining popularity in residential and non-residential applications, mainly in Europe. Currently, panels are being manufactured in a limited number of places in North America, which allows CLT to be used in a few projects while trade organizations and governmental agencies adopt specifications and codes for its use. CLT is being used in Europe as the structural system for eight and nine story buildings with proposals up to seventeen stories. CLT is an engineered wood product consisting of glue laminated wood boards, approximately 20-60mm …

A Multi-Performance Comparison Of Long-Span Structural Systems, E. Douville, B. Thompson, Corey T. Griffin, Kpff Consulting Engineers

Research-Based Design Initiative

When a building requires a long span, especially on the ground floor of a multi-story building, the long span often determines the structural system used early in the design pro-cess without any other consideration. Commercial and residential buildings are responsible for roughly 40% of all carbon emissions and energy use, more than any other sector in the USA. Moreover, this excludes the significant energy and emissions required to extract, process, trans-port and assemble building components. Globally, the production of cement alone accounts for 4% of carbon dioxide emissions. Consequently, reducing the environmental impact of building construction and operations is critical …

A Critical Assessment Of Concrete And Masonry Structures For Reconstruction After Seismic Events In Developing Countries, Heather Mcwilliams, Corey T. Griffin

Research-Based Design Initiative

Overview: The infrastructures of developing countries, old and new, are in severe danger of the next natural disaster, only due to the fact that there is zero concern for the overall use of materials. And although the awa reness of poor construction tech niques have been presented, engineers and arch itects are continuously proposing systems tha t are destined to be hazards once the next disaster hits. Not only is the use of concrete economica lly unsustainable, but it is also the most vulnerable material when seismic activity hits the surface. As the international community helps developing countries such as …

Efficacy Of Replacement Windows In Building Energy Retrofits: A Post Occupancy Evaluation, Chris Rockhill, Heidi Crespi, Corey T. Griffin, Boora Architecture

Research-Based Design Initiative

The thermal performance of replacement windows has made considerable progress in a short time frame. Few studies have been carried out with regard to application of new and retrofit windows to pre-retrofit windows. The goal for this energy retrofit is occupant comfort, as 80% of a buildings energy use goes toward maintaining this standard.Any effort to make this load more efficient is worth investing and warrant post occupancy evaluation to make more informed decisions about future investments. This study gives great insight into the potentials, positives and negatives for utilization and employment of data loggers with thermal couples, infrared thermography, …

Comparing The Embodied Energy Of Structural Systems In Parking Garages An Analysis Of Three Built Projects: Cellular Steel, Precast Concrete And Post-Tensioned Concrete, Corey T. Griffin, L. Bynum, A. Green, S. Marandyuk, J. Namgung, Kpff Consulting Engineers

Research-Based Design Initiative

The structure of a typical office building contributes roughly one-quarter to one-third of the total embodied energy. Although the occupation phase of a building’s life cycle currently dominates energy use, as operational energy use is minimized through high-performance design, construction and equipment, embodied energy will play a larger role in the overall energy consumption of a building. Consequently, the structural system should be a primary target for reducing the embodied energy of a building. Parking garages offer an ideal case study for comparing the embodied energy of a variety of structural systems. As above grade parking garages have little operational …

Computational Modeling Of Baffled Disinfection Tanks, Zachary H. Taylor, Qing Xu, Jordan M. Wilson, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The present study focuses on understanding the flow dynamics of baffled disinfection contact tanks through the use of computational fluid dynamics (CFD). In particular, we seek to address the key question: for a given footprint of a contact tank with a fixed inlet configuration, how does the hydraulic efficiency of the tank depend on the configuration of internal baffles? The benchmark contact tank geometry in our study is shown in Figure 1. In order to define guidelines for hydraulically efficient baffle tanks, we perform a total of 36 high-resolution three-dimensional simulations to quantify the efficiency of a laboratory scale tank …

Roof Drainage: Not My Problem ... Maybe, John Lawson

Architectural Engineering

Many structural engineers are surprised to learn that the International Building Code (IBC, 2009) requires the roof structure to be engineered for standing water weight in the vicinity of the drains and scuppers regardless of roof slope. In addition, some low-slope roofs also require special attention for water weight and stiffness for safety against ponding failures or protection against accelerated roofing deterioration. With a mixture of overlapping design disciplines between the architect, plumbing consultant and structural engineer, proper roof drainage is often not fully addressed in building design and can lead to catastrophic collapse.
