Greencore Homes: Building Carbon-Negative Housing with Natural Materials

Greencore Homes is moving beyond net zero by using natural materials like hemp, lime, and wood fibre to create carbon-negative housing. Their approach focuses on locking embodied carbon into the building structure while ensuring operational energy is offset by on-site solar generation and battery storage. Through the use of materials passports and post-occupancy sensor data, the company provides independent evidence of carbon performance. Their recent project, The Canopies, demonstrates how these high-performance standards can be applied to both private and affordable housing on a commercial scale.

Hemp and lime are great for breathability, but I want to see the actual maintenance costs over ten years. Natural materials often require more upkeep than standard brick and mortar. If the homeowners can't manage the envelope, the energy performance drops.

The use of Madaster for materials passports is the real win here. We need standardized reporting on embodied carbon before these natural builds can move from niche to mainstream. Without a common accounting framework, investors won't value the carbon sequestration.

Claiming a negative energy bill depends entirely on the export tariff and battery capacity. If the grid can't take the export or the tariff crashes, the economic model shifts. Did they specify the battery size per unit for these 42 homes?

Interesting to see a developer focusing on the embodied carbon of the wall panels. Most just slap some PVs on the roof and call it net zero. The BIOND panels seem like a practical way to scale natural construction.
