During summer 2015, a study was conducted to characterize effects of tree species and shade structures on outdoor human thermal comfort under hot, arid conditions. Motivating the research was the hypothesis that tree species and shade structures will vary in their capacity to improve thermal comfort due to their respective abilities to attenuate solar radiation. Micrometeorological data was collected in full sun and under shade of six landscape tree species and park ramadas in Phoenix, AZ during pre-monsoon summer afternoons. The six landscape tree species included: Arizona ash (Fraxinus velutina Torr.), Mexican palo verde (Parkinsonia aculeata L.), Aleppo pine (Pinus halepensis Mill.), South American mesquite (Prosopis spp. L.), Texas live oak (Quercus virginiana for. fusiformis Mill.), and Chinese elm (Ulmus parvifolia Jacq.). Results showed that the tree species and ramadas were not similarly effective at improving thermal comfort, represented by physiologically equivalent temperature (PET). The difference between PET in full sun and under shade was greater under Fraxinus and Quercus than under Parkinsonia, Prosopis, and ramadas by 2.9-4.3 °C. Radiation was a significant driver of PET (p<0.0001, R2=0.69) and with the exception of ramadas, lower radiation corresponded with lower PET. Variations observed in this study suggest selecting trees or structures that attenuate the most solar radiation is a potential strategy for optimizing PET.
In 2018, the United States generated 37.4 million more U.S. tons of paper and cardboard material compared to in 1960 (EPA, 2020). As the United States produces a disproportionate amount of packaging waste every year when accounting for population size, it has become increasingly difficult to mitigate waste production, lessen the environmental impact of generating more paperboard materials, and move towards a more ethical circular economy. In efforts to adopt the principles of a green economy, deviate from the linear supply chain model, minimize packaging waste, and encourage more sustainable lifestyles, we developed a business centered around a circular, service based model called Room & Cardboard. Our initiative collects cardboard waste generated in and around the ASU community and repurposes it for dorm-style furniture available for students to rent throughout the school year. Using cardboard, we have built prototypes for two products (desk lamps and shoe racks) that are sturdy, visually pleasing, and recyclable. Our initiative helps to reduce cardboard packaging waste by upcycling cardboard waste into products that will increase the lifespan of the cardboard material. At the end of the product’s life span, in cases of severe damage, we will turn the product into a seed board made with blended cardboard paste that can then be used to plant a succulent we will make available to students to buy as dorm decor. The feedback on our initiative through online surveys and in-person tabling has generated enough traction for Dean Rendell of Barrett, the Honors College at Arizona State University to consider a test-drive of our products in the upcoming Fall semester.
The purpose of this thesis is to contextualise Hindsight, a sustainability-focused historically based city-simulation and resource management game built by the author. The game and game engine were coded from scratch using the C# programming language and the Unity game development suite of tools. The game focuses on the management of the city of London in two time periods, London from 1850 and the other set in 2050. Both versions of the city are divided into 21 zones, each of which can be managed by the player through the construction, upgrading, or destruction of various buildings within the zone. The player must manage both the city’s resources and the resources of the environment upon which the city depends in order to bring about a more sustainable future and bring the 2050-era version of the city back from the brink of environmental devastation. Along the way, the player must address the cultural views of the society they are managing to ensure their reforms will be accepted and can also see those views slowly change over time. The goal of the game is to provide an interactive learning experience for both the historical element of London and the importance of making sustainable choices.
For the honors thesis project, a group of five individuals collaborated to design and implement a sustainable business in the ASU community. Kandi Society is a rising jewelry brand whose top priorities include giving recycled plastic a new purpose, philanthropy, and making a welcoming, creative environment for our customers. We designed the Eco-Bead with 3D CAD modeling and produced it through a process called plastic injection molding which is explained in detail in the final paper. Kandi Society instilled a positive impact on ASU students by igniting a sustainability spark and increasing interest in repurposing materials in the future.
