For all properties, there is a strong argument that efforts should be first focused on improving the building fabric to reduce energy demand, before considering renewable generation to meet energy needs. All buildings should seek to minimise carbon emissions in accordance with the energy hierarchy:
Fabric First Approach - The Energy Hierarchy
- Be lean: use less energy
- Be clean: supply energy efficiently
- Be green: use renewable energy

Be Lean
Buildings only lose heat in a relatively small number of ways. A ‘fabric first’ approach to building energy performance is based on maximising the performance of the main components and materials that comprise the building fabric itself, to reduce energy demand This can help to reduce bills and carbon emissions whilst also ensuring that the building is properly maintained and protected from the elements. Fabric improvements focus on:
- Improving air-tightness and eliminating draughts
- Increasing levels of insulation – walls, floor and roof
- Optimising solar gain (heat from the sun) through the design of openings and shading
- Enhancing natural ventilation and using heat recovery where appropriate
- Using the thermal mass of the building fabric to assist in heat retention and cooling
Early consideration of building fabric performance will make the building more sustainable (and less costly to run) than simply switching to a renewable energy source alone.
Be Clean
Once energy demand has been reduced, the provision of heat and energy should utilise efficient fuels, equipment and heat distribution systems, and avoiding energy wastage.
Be Green
Once the above issues have been satisfactorily addressed, the provision of energy from renewable sources should be the next focus.
