Pre-Occupancy Training With Virtual Reality, Portland State University. School Of Architecture, Opsis Architecture

Research-Based Design Initiative

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 …

Rock Creek Middle School Daylighting Analysis: Existing And Proposed Spaces, Razieh Hosseini Nezhod, Ashley Mcdaniel-Harpster, Sergio Palleroni, David Posada, Rosemary Hill, Bora Architects

Research-Based Design Initiative

Bora is starting design work on a conversion of Rock Creek Middle School (completed by BORA in 2010) into a high school. This conversion was always envisioned and will soon become a reality. The project will double the size of the existing school, with additional structure being added lo most sides and even the roof of one wing. The will impact existing daylight access in various ways that we'd like to understand better. The goal of this research project is to help us understand existing daylight conditions in areas that will be impacted by proposed additions, leading to informed design …

Hacker Passive Cooling Design, Portland State University. School Of Architecture

Research-Based Design Initiative

We initially started this project with the sole mission of analysing the total greenhouse gas emissions of the new library using the Greenhouse Gas Emissions Analysis Calculator (or GGEA) developed by PAE. During our first visit with PAE, we were informed of the exponential effect refrigerants have on ozone depletion. Some having a global warming potential factor of more than 1800 times that of CO2. This prompted us to make Passive Cooling and eliminating refrigerants our number one goal for this project. From this analysis we were able to discover the EUI and the carbon footprint for Code, Better, and …

Use Patterns Of Breakot Spaces At Roosevelt High School, Portland State University. School Of Architecture, Bassetti Architects

Research-Based Design Initiative

The objective of this research is to observe and analyze the use patterns of flexible breakout spaces at Roosevelt High School. Use patterns are recorded through observation of movement, behavior, length of stay, and activity. Environmental analysis of light, sound, and temperature in the breakout spaces were recorded. Two observational and analysis studies were recorded with users typically spending an average of one minutes or less in the spaces, with cell phone use as the main activity. An additional observational study, several weeks later, utilized a model for breakout spaces. Some findings show correlations with learning pedagogy of breakout spaces …

Skylight Design Optimization, Robert Wilson, Sarut Choothian, Srg Partnership

Research-Based Design Initiative

The Gonzaga Integrated Science and Engineering Building is a 65,471 SF building set for completion in 2018. Located at a critical intersection between disciplines, and with a bridge to the existing PACCAR building, this new endeavor offers the opportunity for true multidisciplinary interaction. The focus of this research affects a critical area of the program. Specifically, to provide natural light to interior spaces located within this zone of interaction.

In order to foster the type of interpersonal connections that this new center hopes to facilitate, attanding to user comfort becomes a primary focus of utmost importance. Well implimented daylighting has …

Milwaukie Ledding Library Cooling System Optimization, Portland State University. School Of Architecture

Research-Based Design Initiative

The Milwaukie Ledding Library (MLL) by Hacker Architects is a new construction 20,000SF project in Milwaukie, Oregon. The City of Milwaukie, the client, wanted to target high sustainability goals, pursuing the Energy Trust of Oregon's path to a net-zero program and LEED certification. The initial research proposal incorporated passive cooling to optimize hydronic radian slab cooling using air-to-water heat pumps designed for radiant heating. Dedicated to a cooling strategy taking advantage of as many passive elements as possible given time, design, and budget constraints, Hacker and PAE considered adding operational or actuated windows to aid with night flush as well …

Evaluating The Impact Of Glazing Orientation On Daylight Penetration Using Autodesk Insight, Randy Mueller, Srg Architects

Research-Based Design Initiative

The objective of this research project was to evaluate how glazing orientation impacts daylight penetration into a building. A Revit shoebox model of a room containing glazing on a single wall was constructed and Autodesk Insight was used to perform the daylighting analysis. Maximum daylight penetration was achieved when the model was analyzed with glazing orientated toward the east or the west. However, northern and southern glazing orientations produced a more consistent and uniform distribution of daylighting throughout the room. The results demonstrate the importance of glazing orientation when incorporating natural light into a building design.

Daylighting Optimization Study: Rock Creek High School Commons Skylight Optimization, Razieh Hosseini Nezhad, Heather Mcginn, Nicholas Papaefthimiou, Rosemary Hill, Bora Architects

Research-Based Design Initiative

The aim of this study is to optimize the shape of the skylights in order to enhance daylighting. Rhino, Diva, Grasshopper, and Galapagos ore the softwares utilized to test differing shapes on top and bottom of the shaft of the skylight, and the findings show preference to those with beneficial impacts on Spatial daylighting autonomy (sDA) of greater than 55% and Annual Solar Exposure (ASE) of less than l 0%. Selecting metrics within the above parameters result in optimal skylight geometry with highest daylighting output. The initial purpose of the experiment was to optimize the design of the skylight shaft …

Zgf Structure Revisted: A Study In Mass Timber For Reed Residence Hall, Portland State University. School Of Architecture

Research-Based Design Initiative

A study in the benefits of designing with CLT and Mass Timber versus PT Concrete and design flexibility between the two systems.

Virtual Reality & Gamification For Pre-Occupancy Training, Corey T. Griffin, Jenny Rodriguez, Gwen Ward, Bynum Laboratories, Opsis Architecture

Research-Based Design Initiative

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 …
