Our People

Hannah Jones

Hannah 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.


Toby Cambray

Toby 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.


Emma Mathias-Jones

An experienced Building Physics/Sustainability Engineer with over four years’ experience. Emma is an AECB certified Passivhaus Designer, Low Carbon Consultant, Lighting designer, undertakes the Dynamic Simulation Modelling (IES VE) for Overheating and Part L calculations. Holding a degree in Architecture and Environmental Design from The University of Nottingham (Meng and RIBA Part 1) allows her to take a broad, holistic view of building design and low energy optimisation. She is currently working towards becoming a Low Carbon Energy Assessor (LCEA).


Louis Dawson

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.


Kasper Maciej

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.
