Andrew Payne

As one of the founding Directors Andrew has been instrumental in developing the company from being a traditional M&E Services designer to a highly technical consultancy offering integrated Building Physics, Passivhaus and building fabric performance led solutions, alongside innovative M&E solutions.

He has also understood the importance of the business remaining at the front of information technology based knowledge systems and CBG were early adopters of Quality Assurance, Business Support software systems, advanced thermal modelling and BIM.

Part of CBG’s success has been its people and culture in developing staff from graduates to ultimately becoming part of the senior management team. This is something many of our long-term clients have respected and in some cases assisted in.

Andrew is always keen to question the ‘normal’ approach to the design and delivery of projects and is currently working with our building physics team to consider how optimising the fabric design can greatly reduce the M&E loads and whole life cycle costs. He also believes that this knowledge can and should be developed across all sectors including transport.

What Andrew brings to clients is not only technical experience spanning over 35 years but a deep understanding of the importance of defining the project need, finding appropriate technical solutions, reducing complexity and removing risk to successfully deliver the project.

Graham Woodroofe

Graham’s experience includes schools, universities, student accommodation, multi residential, private residential, hotels, leisure facilities and historic listed buildings. The breadth of Graham’s experience means he know what works and what doesn’t. A champion of the use of BIM throughout all aspects of design development and pushes for full integrated design and modelling on projects. Each time his goal is to engineer services that integrate seamlessly into the architecture and similarly providing easy-to-use building services to create truly comfortable buildings. Graham believes that ultimately creating buildings are about people, they influence the way we behave and interact and producing a great building comes down to the individuals involved.

Leading the mechanical design and building physics/sustainability teams Graham has a keen desire for shaping environmental design including optimising building performance which includes the work on a series of sustainable building exemplars including the application of PassivHaus to large education buildings. A passion for passive design and understanding how buildings respond to their environment has been complemented by an interest in how people interact with the buildings that they occupy. Good design is about being absolutely appropriate to the client, the project and the wider environment.

With a similar keen interest in historic architecture, historic buildings and heritage assets Graham is able to apply experienced environmental design skills and practical knowledge of building services to implement designs that are both appropriate and are optimised for building conservation.
