PCM

This project explores how Phase Change Materials (PCMs), specifically paraffins, can be employed to regulate household temperatures without relying on electricity. Amidst the climate crisis, high greenhouse gas emissions, and resource depletion, our proposal aims to utilize PCMs encapsulated within walls as an eco-friendly heating and cooling solution. With the capacity to sustain a comfortable temperature range year-round, PCMs could significantly reduce energy consumption by replacing conventional air conditioning systems. The discussion covers their advantages, challenges, and potential applications in sustainable architecture.
