Climate Action · Youth Innovation · Low-carbon Product Proposal
Our team “Double-LT” proposed **Smart Green Home-stay**, a replicable low-carbon model for rural revitalisation. The solution integrates: • Rooftop PV (ABC solar cells) for on-site clean power and carbon reduction; • Water harvesting & recycling (rain/spring/greywater) for potable and non-potable reuse; • Temperature-control wall systems (PCMs/ICFs/SIPs) to stabilise indoor climate and cut HVAC load. The aim is an immersive, eco-friendly stay that balances tourism income with measurable emissions and water savings.
Two things won judges over: **systems thinking** and **replicability**. Rather than a single gadget, we showed how PV, water reuse and thermal envelopes reinforce each other around one homestay so revenue, comfort and emissions reduction move together.
Narrative discipline mattered: turning scattered technical pieces into a single spine—problem → constraints → options → metrics—kept the deck tight and decision-oriented. Assigning work by “decision pages” ensured every exhibit earned its slide.
If iterating, I’d add a light **LCOE/LCCA** and a simple **bill-of-materials** to make cost/benefit legible for local operators. On measurement, a **field-data plan** plus a small replication kit would let other villages copy with minimal engineering debt.
Teamwise, early scope guardrails helped; we could have prototyped visuals sooner. Next time I’d time-box a “visual sprint” first, then back-fill analysis so the end-state stays crisp.
