Sustainable fit-out

The lowest-carbon office is usually the one that keeps the most of what is already there. A sustainable fit-out starts with reuse, then chooses carefully what to add, and is honest about what it achieves.

Most of a fit-out’s environmental impact comes from the materials it uses and throws away, not just the energy it consumes afterwards. Reusing partitions, ceilings, flooring and furniture, and choosing products that can be repaired and reconfigured, makes a bigger difference than most people expect.

Energy still matters, for running costs as much as carbon. Minimum energy-efficiency standards already apply to commercial lettings in England and Wales, and the government has consulted on raising them, so a building’s EPC rating is worth checking before you commit to a lease.

What it involves

Where the impact is

Reuse and refurbishment

Keeping what still works, and refurbishing furniture and finishes rather than replacing them.

Materials

Durable, repairable products with recycled content and clear information on where they come from.

Energy

Efficient lighting and controls, sensible zoning of heating and cooling, and an eye on the building’s EPC.

Waste

Surplus furniture reused or donated, and construction waste separated and recorded.

What to get right

Avoid the greenwash

Sustainability claims are easy to make and hard to check. Be specific: what was reused, what was recycled, what changed in energy use. Numbers you can stand behind are worth more than a long list of features.

Certification schemes such as BREEAM, NABERS UK and WELL measure different things: overall building performance, actual energy use in operation, and occupant health and wellbeing. Decide which, if any, matters to your organisation before designing to one.

  • Survey what can be reused before you design anything.
  • Ask suppliers about take-back schemes, spare parts and warranties.
  • Keep a record of materials and waste for your reporting.
  • Measure energy use after you move in, not just at design stage.

A good fit if…

  • You have sustainability targets and need a fit-out that supports them.
  • You want to cut cost and carbon by reusing more.
  • You are weighing up buildings with different energy ratings.

Probably not the right fit if…

  • You want a certification badge without changing how the project is done.

Devon Wildlife Trust

Reusing a fire-damaged, listed mill rather than building new, Devon Wildlife Trust created a headquarters with its history intact, its mill machinery restored and stream-side habitats opened up around it.

Questions

What clients usually ask

Does a sustainable fit-out cost more?

Not necessarily. Reusing existing elements often costs less than replacing them. Some higher-performance products cost more up front but less to run and maintain.

What is embodied carbon?

The carbon emitted in making, transporting and installing materials, as opposed to the energy used to run the building. For a fit-out, it is often the larger share.
