Solar Parking Lot Analysis: Smart Investment Or Waste Of Capital, Jared J. Davis
Solar Parking Lot Analysis: Smart Investment Or Waste Of Capital, Jared J. Davis
Construction Management
In the last couple decades solar panels have been developed into a sustainable and effective method for harnessing clean energy. Today, solar panels have been engineered into solar roadways. Solar roadways are structurally engineered solar panels which can be installed in the Earth, driven on, and can replace the need for traditional asphalt roads. These solar roadways also include built in LEDs which mimic road lines and light up wildlife crossing the road, making these road panels a very safe alternative to traditional asphalt roads. This senior project is an analysis of solar roadways and their capabilities when applied to …

Dc-Dc 4-Switch Buck-Boost Converter For Energy Harvesting From Elliptical Machines, Alexander C. Samietz, Gustavo Guzman
Dc-Dc 4-Switch Buck-Boost Converter For Energy Harvesting From Elliptical Machines, Alexander C. Samietz, Gustavo Guzman
Electrical Engineering
The senior project report documents the process of replacing the network of resistors inside an elliptical machine with a DC-DC buck-boost converter. The buck-boost DC-DC converter accepts a wide input range of 5-60 Volts, with an output of 36 Volts for the most efficient use of the already available microinverter. The microinverter reclaims the lost energy and safely distributes it back to the electrical grid. The addition of this project reduces heat emissions from wasted energy and shrinks the carbon footprint of its users.
Using Net Groundwater Extractions For Farm Level Groundwater Sustainability Monitoring, Daniel J. Howes, Morgan Whinery, Eric Limas, Dan Vink
Using Net Groundwater Extractions For Farm Level Groundwater Sustainability Monitoring, Daniel J. Howes, Morgan Whinery, Eric Limas, Dan Vink
BioResource and Agricultural Engineering
The Cal Poly Irrigation Training and Research Center (ITRC) has developed a method for computing net groundwater extraction and recharge at the farm level for district management and regulation of sustainable/safe yields. This method is called Net To/From Groundwater (NTFGW). Net groundwater extraction is preferred for assessing sustainable yield in unconfined aquifer systems over direct metering of gross groundwater pumping. A recent pilot project with the Lower Tule River and Pixley Irrigation Districts’ Groundwater Sustainability Agencies (GSAs) compared actual metered groundwater pumping, surface deliveries, and evapotranspiration to the NTFGW outputs on 19 farms within the GSAs over a 3-year period …
Next Generation Protocol: Innovating A Resilient Future, Andrew Steven Rudnick, Jamie Cannady, Joe Decesaro, Juan A. Ortiz Salazar
Next Generation Protocol: Innovating A Resilient Future, Andrew Steven Rudnick, Jamie Cannady, Joe Decesaro, Juan A. Ortiz Salazar
Materials Engineering
Conventional practices do not account for product life beyond end-of-sale – these practices are not sustainable. We have developed an end-of-life protocol that includes a metric that we call the Recovery Rating. The objectives of this Next Generation Protocol, beyond supporting the United Nations’ Sustainable Development Goals, are to encourage the production of goods designed for recovery and to promote the collaboration between consumers, the public, and the private sector to recover goods at their end-of-life. The Recovery Rating that we propose evaluates and quantifies recovery potential of products. The Recovery Rating, which is normed against embodied energy from the …
Student Led Service-Learning Initiative: Installation Of Photovoltaic Water-Pump Systems In The Ecuador Amazon Rainforest, Kelly M. Williams
Student Led Service-Learning Initiative: Installation Of Photovoltaic Water-Pump Systems In The Ecuador Amazon Rainforest, Kelly M. Williams
Construction Management
The National Electrical Contractors Association (NECA) student chapter at California Polytechnic State University in San Luis Obispo, California was selected by an association called ELECTRI International to participate in their Student Community Service Initiative program. The goal of the program is to “Encourage construction management and electrical engineering students to take an active role in improving access to electricity in developing communities” (“Student Passport Program”). This paper summarizes the findings of a student-led project made possible by ELECTRI International’s program. The project included coordinating, funding, and executing a project to facilitate the installation of photovoltaic water pump systems to indigenous …

Medicial Clinic At Mission Twentyfive35 Vocational Village - Dominican Republic, Sarah C. De Los Reyes
Construction Management
This community medical clinic will be the first of its kind in the rural town of Villa Tapia, Dominican Republic It is Phase II of a five-phase master plan drafted by religious organization Mission Twenty-Five35, founded by the Romano family The team consists of Cal Poly undergraduate students: Griffin Chierici (Architecture), Erica Croft and Tommy Sidebottom (Architectural Engineering), and Sarah De Los Reyes (Construction Management), backed by the guidance and support of non-profit organization Journeyman International and A/E firm Smith Group JJR The task was to design a clinic that would serve as a pediatric and urgent care center but …
A Comparative Study Of The Leed And Well Building Standards, Brent J. Zavada
A Comparative Study Of The Leed And Well Building Standards, Brent J. Zavada
Construction Management
Our current environmental and public health conditions have led our industry to create sustainability standards that address both of these current problems. With the addition of the WELL Building Standard, the first standard to solely focus on human health and wellness, it is now possible to promote public health, environmental conservation, and owner profits all in one project. This study looks to overlap the well-known LEED Certification standards with the new WELL standards to assist project teams in fully understanding what needs to be accomplished in order for their project to be on track for both certifications. It is meant …

The Setty Family Foundation 2018 Ashrae Applied Engineering Competition, Joshua Heath
Construction Management
The Setty Family Applied Engineering Challenge tasked my project group with designing a temporary shelter specifically for refugees in Eastern Europe to be used by governments, municipalities, and humanitarian agencies that is cost effective, portable, sustainable, and provides all necessary domestic needs. After months of research and design, we have developed the PolyShelter ; an eight-person structure erected to provide comfortability and safety to those in need. PolyShelter is designed to withstand the harshest of climates, provide exceptional insulation, and incorporate a rainwater collection system sufficient enough to support each unit. PolyShelter proves itself to be an economically viable solution …
Feasibility Analysis For Reclaim Device During Shotcrete Application, Cameron Neil Berkins
Feasibility Analysis For Reclaim Device During Shotcrete Application, Cameron Neil Berkins
Construction Management
Shotcrete application has proven advantages over cast-in-place concrete under many different situations. Ease of access, minimal formwork, and higher productivity are prime examples. Its uses have exponentially increased through technical innovations to improve the ready-mix, nozzlemen technique, application surfaces, and to ensure higher dependability of the equipment. Unfortunately, concrete waste is still one of the highest percentages of overall waste in the construction industry. Shotcrete rebound, the material that falls from the wall due to lack of cohesion during installation, has slowly been reduced due to ready-mix alterations over the years, but effective recycling processes have yet to be implemented. …
