Step-by-Step Process
Assessment & Planning

• Inspect the building for heat loss, air leaks and insulation issues

• Conduct an energy audit to identify efficiency gains

• Set project goals (e.g., energy reduction, comfort or sustainability)

• Evaluate costs, materials and feasibility

​
Design & Specification

• Set insulation and airtightness targets

• Choose eco-friendly, high-performance materials

• Plan ventilation systems for air quality in airtight spaces

• Ensure compliance with energy regulations

 
Preparation

• Address structural issues or dampness

• Source sustainable materials

• Inform stakeholders of timelines and disruptions

 
Fabric Improvements

• Add insulation: external walls, internal walls, lofts, roofs and floors

• Upgrade to double or triple-glazed windows

• Enhance airtightness with seals and membranes

• Address thermal bridging at key junctions

  
Testing & Validation

• Perform airtightness tests and thermal imaging

• Ensure energy performance meets targets

 
Handover & Maintenance

• Train occupants on ventilation and maintenance

• Provide detailed documentation of upgrades

• Offer ongoing support to monitor performance

 
 
Benefits of Fabric-First Retrofit

• Reduced energy demand and heating costs

• Improved comfort and indoor air quality

• Long-term energy efficiency and lower carbon footprint

• Higher property value and future regulation compliance

• A fabric-first approach lays a solid foundation for sustainable, energy-efficient buildings, ready for additional green technologies
