We build homes that are Better Than Net Zero. Most housebuilders define net zero only in terms of operational carbon and energy efficiency.

Our method of construction and the materials we use guarantees the structure of each home achieves better than zero embodied carbon.

Our developments are designed to achieve ultra-low embodied carbon overall and a net zero energy balance in occupation.

A Typical
Greencore Home

Greencore home bisection
  1. Roof-Mounted Solar PV We target 100% of energy from renewables
  2. Air Tightness Homes are built to be very airtight reducing heat loss
  3. Well-Insulated Building Envelope Low U-Values for floors, roof and walls, External biond wall panel, Triple-glazed windows
  4. Mechanical Ventilation & Heat Recovery Homes are ventilated and the air is filtered. Heat is recovered from the expelled air
  5. Air Source Heat Pump and/or Electric Heating Efficient, low-carbon heating solution using no fossil fuels
  6. Post Occupancy Evaluation Sensors installed to evauate energy in use
  7. Optimised Orientation & Window Proportions Balance between energy efficiency, overheating and daylight
  8. Optimised Building Form Simplified building shape to reduce heat loss areas and complex junctions

Our Biond Panel System

Our Biond panel is an innovative closed timber frame panel insulated with hemp, lime and natural wood fibre. The panels form the structure of our homes. All of the timber is sourced from sustainable forests. A typical external wall panel locks up over 30kg of CO2e per square metre. Our Panels are BOPAS (Build Offsite Property Assurance Scheme) accredited.
