In this episode of Renewing Homes, I sit down with Peter Darlington of Solar Homes and Cooper Le of 4 Elements to explore Peter's journey from stucco contractor to one of Canada's leading residential retrofit specialists.

What began as curiosity about net zero homes led Peter to undertake one of Canada's first CHBA Net Zero labelled renovations on his own home… Several years before the label even existed! That experience transformed his business and continues to shape how he approaches residential retrofits today.

Our conversation explores the importance of planning, building science, and collaboration in delivering successful retrofits. We discuss homeowner motivations, the comfort and health benefits of high-performance homes, lessons learned from over a decade of living with a cold-climate heat pump, and the opportunities and challenges of scaling quality retrofit work across the industry.

Whether you're a homeowner, contractor, designer, energy advisor, or policymaker, this episode offers practical insights into what it takes to deliver better retrofit outcomes.

• Curiosity and continuous learning can transform both careers and businesses.
• Deep energy retrofits require thoughtful planning and collaboration long before construction begins.
• Comfort, health, and resilience are often stronger homeowner motivators than energy savings alone.
• Living with a cold-climate heat pump for over a decade provides valuable real-world performance insights.
• Successful retrofits balance technical performance, durability, practicality, and cost.
• Scaling residential retrofits depends on simplifying good building science and improving industry capability.
• Every home is different, making thoughtful planning essential to achieving the best outcomes.
