Captured September 18, 2009.The Framework Plan: creates a strong and poetic metaphor of historic Tanner Creek; it addresses the deeper meanings of the natural cycle of water collection and storage, the visual relationship between water and land, and the natural and social life that they support; provides a great variety of spaces, both in terms of use and scale; reaches out to promote a synergy between civic and private development initiatives; [and] establishes strong, guiding principles to promote a sense of place. The plan relies on simple elements which are both common and unique to the city. [From the Plan

EC3 and Embodied Carbon Reduction

The objective of this research was to use the Embodied Carbon in Construction Calculator (EC3) tool to evaluate the embodied carbon emissions in several material categories, allowing for specification and procurement of low carbon options. The case study for this research is the Shiley-Marcos Center for Design & Innovation (University of Portland), an adaptive reuse project currently in the late design and procurement phase of the construction process. This research was intended to contribute to the research done during the design phases related to the Whole Building Life Cycle Analysis (WBLCA) using Tally. I worked primarily with Heather DeGrella and Kelli Kimura from Opsis, as well as Stacy Smedley from Skanska, who has extensively worked on developing EC3. Throughout the research, I worked in two EC3 files related to the two primary aspects of this research: • Establishing comparisons to baselines using the construction estimate to determine the possibility of carbon reductions for the Shiley-Marcos project • Exploring EC3’s optimization and compatibility with Tally In the file related to the construction estimate, I took the material and quantity data, researched the proper specifications, and added them into EC3. I then selected an EPD for each material unit and used EC3 to create comparisons to baselines. From there we were able to see areas of improvement and various baselines for the specified materials. The second file we analyzed the differences between the embodied carbon amount that was reported directly out of Tally versus what EC3 calculated from the same materials and quantities.https://pdxscholar.library.pdx.edu/research_based_design/1096/thumbnail.jp

Pre-Occupancy Training with Virtual Reality

Project Overview: Opsis Architecture has teamed with Portland State University’s Research-Based Design Initiative to study occupant behavior and energy consumption. The relationship between people and building control systems is a critical factor in overall building energy performance. Conventional energy models rely on static, overly simplistic patterns of occupant behavior and are unable to provide energy performance predictions that reflect realistic use. Thoughtfully designed passive systems are ineffective unless operated as intended, resulting in a performance gap between predicted energy consumption and measured energy consumption post-occupancy. Utilizing virtual reality (VR) simulation with game engine technology, this team is studying the potential of VR to both predict and influence user interaction within specific spaces and environmental conditions. This study will take place over two quarters, Fall 2017 and Winter 2018. During the fall quarter, we are focusing on new ways of training by analyzing VR’s gaming capabilities to build upon the users’ emotional relationship with a space, improving their ability and desire to better utilize passive and advanced systems such as shades, ceiling fans, lighting controls, and operable windows. The finished product will transform the way the profession thinks about post-occupancy training, energy modeling, and influencing behavior through design.https://pdxscholar.library.pdx.edu/research_based_design/1084/thumbnail.jp

Virtual Reality & Gamification for Pre-Occupancy Training

The objective of this research is to analyze and compare user behavior and learning retention via gamified and non-gamified virtual reality for use in pre-occupancy training. After completing trials for both gamified and non-gamified virtual reality we issued a standardized post-experience survey to collect data on what the participants learned, then compared and analyzed the results. The benefits of virtual reality and gamification have both been extensively studied and both suggest they are independently effective teaching tools. In our trials we have found that participants who went through the gamified virtual reality training were 50% more likely to come away with the desired learning objectives than participants who went through the non-gamified virtual reality. The benefits of virtual reality and gamification can be effectively combined and retain the benefits of that learning method in this situation. Based on our small sample and our literature review this technology can be used to train a more informed population regarding the effective operation of passive building systems.https://pdxscholar.library.pdx.edu/research_based_design/1085/thumbnail.jp

Erforschung von Methoden der Hardware-Realisierung einer Echtzeit-3D-Erfassung von Objekten Abschlussbericht

The part project analysed new approaches to hardware that is capable of speeding up 3D measuring techniques with actively structured illumination, real time hardware modules were developed. A major result is the conception of a new technique using multi-step LUT processors for 3D image processing. In conjunction with a position memory that provides a high data compression rate, this technique ensures real-time preprocessing and, in some cases, real-time processing of the entire sequence if the Projected Fringe method is used. If the Phase Shift method is deployed, the modules developed by the part project execute all operations at the shortest possible time which is determined by the succession of image recordings. The same applies to the Coded Light approach which references and compares single images while building up the bit plane stack at the same time. An electronic control element with an automatic linearisation function was designed for the active control of a laser light pattern by means of a scanning galvamometer. The control electronics supports recording strategies for backfed sensor signals and detail-specific measuring resolutions.

Biophilia X JEDI

The intersection of biophilic design, justice, equity, diversity, and inclusion provides a unique vantage point from which to design. When viewed as intersecting lenses to design the human state becomes more than utility, health, or productivity and more sustainable designs emerge. How can Biophilic design improve by becoming more inclusive in its process and more inviting to a diverse audience? How can Opsis’s initiatives improve by looking to nature for clues on how to move together toward a common purpose in unison? By creating a diverse culture influenced by nature and a nature-based, design process influenced by a diverse culture, Opsis is creating a unique design process that is responding to our most pressing climate and humanitarian challenges.https://pdxscholar.library.pdx.edu/research_based_design/1003/thumbnail.jp

PCC Rock Creek Post Occupancy Evaluations

The objective of this research is to determine whether the new additions to Building 5 and Building 7 of Portland Community College at Rock Creek Campus fulfill the requirements for the LEED IEQ 7.2: Thermal Comfort-Verification credit for LEEDv2009. Occupants of the new additions will take an anonymous survey regarding their thermal comfort and other aspects of the new additions via SurveyMonkey. If the survey results indicate that more than 20% of occupants are dissatisfied with thermal comfort in the building, a plan for corrective action must be developed to fulfill the requirements of the credit. The results from SurveyMonkey show that 87% and 79% of occupants were satisfied with the thermal comfort in the new additions to Building 5 and Building 7 respectively. According to initial findings, a plan for corrective action must be developed for Building 7 to fulfill the requirements agreed to when the credit was awarded. However, more results should be gathered before making any valid conclusions. The survey could have reached a much broader audience if it was distributed on more days with a larger variety in distribution times.https://pdxscholar.library.pdx.edu/research_based_design/1072/thumbnail.jp
