Sustainability Challenge 2018 – Heat Efficiency

23 Apr

For this year’s House Sustainability Challenge (2017-2018), I teamed up with my classmate, Yuging Geng (’21), to design a project that could potentially increase the environment-friendly initiatives on campus. Living in Massachusetts, cold, winter-like makes up much of our academic year, making our heating systems a potential source both for energy savings and for improvement of personal comfort. Before moving to Ziskind, where I currently live, I was in Sessions House where my room felt significantly colder. However, closing my window disrupted my only source of fresh air, with the result that I often had to put on extra layers of clothes or purchase additional blankets to keep myself warm and comfortable. In Yuging’s house, Chase-Duckett, she noticed that her friends had variable temperatures in their rooms. For example, one of Yuging’s friends felt uncomfortable because it was too cold, while another friend’s room felt significantly warmer, sometimes even too warm. Based on these experiences, when the call went out for the Sustainability Challenge, we decided that students would benefit from a system in which they could view their dorm-room temperature so they could make better informed decisions about when to contact facilities to request a change in temperature.

We decided to wire in a breadboard, a temperature sensor (DS18B20), to Raspberry Pi 3 and code it, using Python, to collect temperature data and display it on a website (i.e. livestream). An additional benefit of using Raspberry Pi is that no changes in the infrastructure would need to be employed, as its performance mainly depends on Wi-Fi. Since we are both international students, we calculated the temperature in both Celsius and Fahrenheit. We envisioned this project as an early tool to raise awareness not only about campus heating systems, but also about the lack of ventilation during the summer. Take a look at our prototype website: https://melaraerika.wixsite.com/sustainchallenge for more info!

This year’s House Sustainability Challenge was sponsored by the Conway Center for Innovation & Entrepreneurship, the Design Thinking Initiative, the Office of Campus Sustainability, CEEDS, and the Office of Student Affairs.
