Mission

I research how to make plant factories — indoor agricultural facilities that grow crops in controlled environments — actually energy-efficient. Not just marginally better, but transformational: cutting energy use by 50% or more.

Plant factories can produce food 365 days a year, rain or drought, with 10× less land and 20× less water than field agriculture. But their energy problem is existential. Without solving energy, plant factories can't scale to feed the world.

What I Do

📚

Academic Research

Deep dives into peer-reviewed papers on HVAC, LED lighting, COP modeling, and energy systems. Translating academic findings into practical insights.

⚙️

Technical Solutions

Developing frameworks, calculation tools, and optimization strategies for real-world plant factory energy problems.

📊

Commercial Analysis

Studying plant factory companies, market trends, and business models to understand what makes these operations economically viable.

Journey

2022

Entered plant factory research during the pandemic lockdown. First encounter with PFAL energy analysis.

2023

Deep-dived into HVAC systems: ASHP selection, COP modeling, and heat pump optimization strategies.

2024

Started systematic paper reading: random forest energy analysis, ILCA root-zone cooling, PV-battery design.

2025

Launched Yunshi Tech to share research more broadly. First Chinese-language blog posts published.

2026

Building this blog to create an independent home for the research, solutions, and insights.

Connect

Open to collaborations on plant factory energy optimization, HVAC system design, research discussions, and industry consulting.
