The Opportunity

Problem

Graduate students in sustainability programs lack seamless integration between climatetech simulation tools and student-friendly coding environments like Jupyter.

Solution

SustainJup embeds climatetech simulation tools like EnergyPlus and HOMER into Jupyter environments via a browser-based plugin. Students upload models, run simulations with one-click integration, and visualize results inline without leaving their notebooks. It handles API calls, data syncing, and error debugging automatically for sustainability-focused workflows.

Target Audience

Graduate students in sustainability programs

Differentiator

First tool optimized exclusively for sustainability grad programs, with pre-loaded templates for common climatetech scenarios like urban heat islands and renewable energy grids.
