Inquiry Framework
Question Framework
Driving Question
The overarching question that guides the entire project.How can we design and implement a "Green Cloud Auditor" dashboard in Tableau to quantify the hidden environmental costs of AI development and empower stakeholders to balance model performance with global sustainability goals?Essential Questions
Supporting questions that break down major concepts.- What are the primary hardware and software metrics (e.g., TDP, GPU/CPU utilization, PUE) required to accurately quantify the energy consumption of an AI training cycle?
- How can we derive carbon dioxide equivalent (CO2e) values from raw energy data, and how does the regional carbon intensity of the power grid influence these calculations?
- How can Tableau’s advanced visualization techniques (such as parameters, calculated fields, and interactive filtering) be used to transform raw telemetry data into actionable insights for cloud optimization?
- What is the quantifiable trade-off between AI model accuracy/complexity and its environmental footprint, and at what point do the marginal gains in performance become unsustainable?
- How can a real-time 'Green Auditor' dashboard be designed to influence the behavior of developers and stakeholders toward more sustainable cloud computing practices?
- Who bears the ethical and financial responsibility for the 'hidden' carbon costs of cloud computing: the cloud provider, the software developer, or the end consumer?

Entry Events
Events that will be used to introduce the project to studentsThe Hidden Bill for GPT-4
Students are presented with a mock 'Environmental Invoice' detailing the precise liters of water and grams of carbon consumed during a single 100-token GPT-4 request. They are then challenged to use Tableau to project the cumulative impact of the university's entire student body using AI daily, forcing them to confront the invisible physical toll of virtual intelligence.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.The Energy Explorer: Foundation and Data Ingestion
Before building the dashboard, students must understand the raw telemetry data that fuels it. In this activity, students will research and define key hardware metrics (Thermal Design Power, PUE, and GPU/CPU utilization) and prepare a dataset representing different AI training workloads (e.g., LLM vs. Computer Vision) across various cloud regions.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'Data Dictionary and Preparation Log' containing a cleaned dataset (Excel or CSV) ready for Tableau ingestion, with documented definitions for every metric.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with ABET-CS-2 by requiring students to identify and evaluate the specific computing requirements (metrics) for the project. It also meets ACM-SEP-SUSTAIN by forcing students to evaluate the raw environmental impact of hardware.The CO2e Engine: Building Dynamic Logic
Students will transform raw power data into environmental impact data using Tableau's logic. They will create 'Calculated Fields' that compute Energy (kWh) = (Power x Time x PUE) / 1000. They will then implement 'Parameters' to allow users to toggle between different regional carbon intensities (e.g., the high-carbon grid of West Virginia vs. the low-carbon grid of Norway).Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA Tableau 'Math-Model' sheet featuring functioning parameters that dynamically update a 'Total CO2e' figure based on selected regions.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with Tableau-CDA-2.2 (Creating Calculated Fields and Parameters) and ABET-CS-2 (Implementing a computing-based solution). It directly addresses the learning goal of applying mathematical formulas to derive CO2e values.The Efficiency Frontier: Analyzing Trade-offs
Students will create a 'Scatter Plot of Diminishing Returns.' On one axis, they will plot Model Accuracy/Performance; on the other, they will plot Carbon Footprint. This activity focuses on visualizing the point where marginal gains in AI accuracy result in exponential increases in environmental cost, using interactive filters to compare different model architectures.Steps

How this activity aligns with the learning objectives & standardsThis activity aligns with ACM-DS-VIS (Identifying patterns) and Tableau-CDA-2.2 (Interactive filtering). It fulfills the learning goal of evaluating technical trade-offs between model complexity and footprint.The Green Auditor Portal: Stakeholder Communication and Ethics
Students will assemble their previous sheets into a cohesive, professional 'Green Cloud Auditor' Dashboard. The focus here is on UI/UX for stakeholders. The dashboard must include a 'Call to Action' section and an 'Ethical Impact Statement' that interprets the data for a non-technical audience (business leaders/policymakers).Steps
