Fabric First

A ‘fabric first’ approach to building design involves maximising the performance of the components and materials that make up the building fabric itself, before considering the use of mechanical or electrical building services systems. This can help reduce capital and operational costs, improve energy efficiency and reduce carbon emissions. A fabric first method can also reduce the need for maintenance during the building’s life.

Buildings designed and constructed using the fabric first approach aim to minimise the need for energy consumption through methods such as:

  • Maximising air-tightness
  • Using super-high insulation
  • Optimising solar gain through the provision of openings and shading
  • Optimising natural ventilation
  • Using the thermal mass of the building fabric
  • Using energy from occupants, electronic devices, cookers and so on

Focussing on the building fabric first, is generally considered to be more sustainable than relying on energy saving technology, or renewable energy generation, which can be expensive, can have a high embodied energy and may or may not be used efficiently by the consumer.

Having energy efficiency integrated into the building envelope can mean occupants are required to do less to operate their building and not have to adjust their habits or learn about new technologies. This can result in less reliance on the end user regarding the buildings energy efficiency.

Fabric first building systems using offsite technologies, such as SIPS, result in higher quality and so better performance, reduced labour costs and an increased speed of build.

Passivhaus, an energy performance standard for dwellings, commercial, industrial and public buildings, also adopts a fabric-first approach to energy efficiency.
