Company Profile

Greengauge Building Energy Consultants launched in January 2011. Greengauge are a building services engineering consultancy that aim to provide clients with a comfortable building meeting their expectations by the most efficient means.

Scope of Services

The team take a holistic approach to building design, based on close coordination with the design team and client to ensure that the building meets and exceeds building regulations and provides a highly satisfactory space to live or work. In keeping with the holistic mantra, the team seek to reduce ‘demand-side’ energy use prior to providing impartial advice on renewable energy systems. We provide full mechanical, electrical and building physics design for small commercial and residential projects, and as mechanical and electrical engineers our recommendations can be developed into full mechanical and electrical designs, for new build and refurbishments. Our services also include energy surveys for businesses and homes providing clients with a strategic plan to optimise their energy use.

Key Personnel

Toby Cambray is a founding partner and leads the building physics services at Greengauge. He holds a BEng in Acoustical Engineering and an MSc in Theory and Practise of Sustainable Design. He is experienced with a variety of tools for assessing whole-building energy efficiency, component performance and moisture risk assessment. He is a member of Technical Working Group 1 (Modelling and Monitoring) for the Centre for Moisture in Buildings, and is a regular guest lecturer at UWE. Hannah Jones is a founding partner and leads the mechanical and electrical design services at Greengauge. After graduating from Warwick University with first-class honours in Engineering Design and Appropriate Technology (MEng), she gained experience with Halcrow before starting Greengauge. Hannah has a very broad range of experience and skills, and brings to bear her deep understanding of fabric performance in designing simple and robust services in harmony with each building. Adam has been a Building Services Engineer for 12 years, originally based in London and more recently the South-West. Having moved from large Building Services consultancies like WSP and ARUP he has widened his understanding of building services to low energy buildings and appreciates the benefits of building fabric in achieving this goal. Adam likes to keep things simple when designing M&E systems wherever practical and has interests in Bau Biology. He lectures at Bath College one day a week. Oscar is a degree qualified mechanical engineer and experienced building services engineer. He is a specialist in 3D/BIM software such as ArchiCAD and makes every effort to integrate and co-ordinate M&E design with other disciplines (architecture, structure, etc.). Oscar is interested in improving the way the information is provided, always looking for more precise, robust, and understandable ways of communication, enabling a smooth journey through the BIM process. He is passionate about the latest technologies and believes IoT (Internet of Things) needs to be adopted rationally in new and existing constructions. He is also in the process of designing and building Greengauge’s own energy monitoring equipment. Kasper is a Building Physics engineer with three years’ experience. Kasper holds a degree in Architecture and Environmental Engineering (BEng and RIBA Part I) at UWE and is currently undertaking his ARB/RIBA Part 2 architecture course also at UWE. He aims to develop a mix of skills, in both architecture and engineering, to achieve better design. Louis has joined Greengauge as a Trainee CAD Engineer. He studied mechanical engineering level 2 at Bath College before joining us. He is currently learning how to develop lighting calcs and the fundamentals of 3D modelling. Hannah Rayner provides admin support for the team and heads up our marketing. She holds a degree in English Literature from Southampton University and has experience in marketing for the cultural sector and in events management.  She assists with business development and also ensures Greengauge meets all necessary Management and Auditing requirements.  Hannah is currently studying for the Certificate in Professional Marketing from the Chartered Institute of Marketing.   Greengauge also have a network of trusted partners/sub-consultants for disciplines like BREEAM.
