Commissioning and Building Performance Evaluation

Better performing buildings mean better performing organisations.


Commissioning and retro-commissioning, or building performance evaluation, help you reduce both first costs and operational costs, create more productive environments for occupants and reduce environmental impact.

In-depth commissioning

For us, commissioning is more than just a tick-box exercise; it’s the only way to ensure a new building’s systems perform as efficiently and effectively as they were designed to do. It’s also a requirement for green building rating systems such as LEED.

During commissioning, we use our wide-ranging expertise to significantly improve performance – giving you more value for your investment. We have specialist skills such as acoustics, façades (building envelope) and audio visual in-house. So we can meet the latest commissioning guidelines and standards from bodies like the National Institute of Building Sciences and the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

We commission systems of all kinds - view some examples.

Better building performance

This expertise also enables us to tackle any issue with an existing building through our independent building performance evaluations – the Arup Appraise approach. We are part of BSRIA’s Soft Landings user group. And we are custodians of the BUS occupant satisfaction evaluation methodology, which is used internationally and backed by a database of some 800 buildings. We are also pioneering our own Energy Bureau to monitor clients’ energy use in real-time and suggest improvements.

In the US, utility company incentives often make our services available to clients at low cost or no cost. This enables organisations to benefit from customised solutions for their buildings that improve their performance or help them retain tenants.

Global, cross-sector building expertise

Clients such as Adidas and Procter & Gamble rely on our building performance expertise to enhance their facilities around the world. And in countries like the UK, we are helping clients meet increasingly tough legislation such as the Carbon Reduction Commitment. By identifying measures to reduce energy, carbon and cost, we helped Ofgem reduce its Display Energy Certificate rating at its London headquarters from G-165 to D-79.

We work across many sectors - including those listed here.
