About us

Evidence-based design for deeply sustainable buildings

The built environment accounts for almost 40% of global carbon emissions. Right now, many organisations and individuals are working hard to drive this number down and slow the path of climate change. We are responding to this challenge. We use our technical knowledge and expertise to create buildings that combine sustainability with wellbeing. In doing so, we help create spaces where people and communities can thrive.

Our history

Greengauge started life on a house boat on the River Avon in Wiltshire. If we’d known back then that we’d grow up to be one of the UK’s leading building engineering consultancies, with 12 highly experienced teammates, and a raft of awards to our name, we might not have believed you. And yet, here we are today, leading the way in our field.

Our story began in 2010 when our co-founder Hannah Jones was working at a large engineering consultancy. Together with Toby Cambray who was finishing his MSc and contemplating his next move, the pair decided to radically re-think the way engineering solutions for buildings are delivered. Unlike the ‘big practices’, Hannah and Toby wanted a new model: an integrated approach where building physics, building services and building design come together for better outcomes. It worked. And, the rest, as they say is history.

Toby Cambray

Toby Cambray

Toby is a founding director 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

Hannah Jones

Hannah is a founding director 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 Lane

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.

Paul Smith

Paul Smith

Paul is an experienced Building Physics Consultant with over twelve years’ experience in low energy building design and has been certified with the PHI as a Passivhaus Consultant for the past 6 years. Paul has an MSc in Sustainability and Adaptation in the Built Environment from the Centre of Alternative Technology. He has amassed a broad range of experience and technical skills across the design and implementation of low energy products, materials, and systems. Paul utilises a range of software and his understanding of fabric performance to deliver robust, simple building design.

Emma Mathias-Jones

Emma Mathias-Jones

An experienced Building Physics/Sustainability Engineer with over five years’ experience. Emma helps manage the Building Physics team, is an AECB certified Passivhaus Designer and Low Carbon Consultant. She undertakes overheating risk assessments, Dynamic Simulation Modelling (IES VE) for Part L calculations, and often helps with the early stage M&E energy strategy reports. Holding a degree in Architecture and Environmental Design from 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), making the office zero-waste, as well as learning more about the circular economy and retrofits.

Oscar Garcia-Mendez

Oscar Garcia-Mendez

Degree qualified mechanical engineer and experienced building services engineer. Oscar is a specialist in 3D/BIM software such as ArchiCAD and he 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-Headshot-website

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.

Mitch Finn

Mitch Finn

Mitch is a Building Physicist, carrying out thermal modelling for Passivhaus, Part L, EPCs and overheating, as well as thermal bridging calculations. Mitch has a masters in Renewable Energy and Energy Management, and qualifications as a Passivhaus Consultant, On Construction Domestic Energy Assessor and a Level 5 Non-Domestic Energy Assessor.

Jack Preece

Jack Preece

Jack graduated with a masters in Civil and Architectural Engineering from the University of Bath, along the way gaining experience in a range of engineering firms from working as a site engineer to being part of international design consultancies. Jack is a Certified Passivhaus Designer and makes use of a range of software to assess the building fabric for interstitial condensation risks and thermal bridges. He enjoys taking a holistic approach to a project assessing mechanical systems that work in conjunction with the building fabric to produce a design responsible for low levels of operational and embodied carbon.

Olivia De Sousa Costa

Olivia De Sousa Costa

Olivia is a building physicist. Her focus is on assessing hygrothermal risk within buildings – both via numerical simulation using the Wufi Pro software and by material characterisation testing. She also carries out thermal modelling for Passivhaus and thermal bridging calculations. Olivia is helping to develop and build Greengauge’s own automated energy monitoring system. She holds a masters degree in Natural Sciences with a focus on physics and chemistry from the University of Bath.

Louis Dawson

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.

Hannah Rayner

Hannah Rayner

Hannah is our Office Manager 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.

We work with some of the world’s most respected architects

We work in partnership with many of the word’s most respected architects. Where they have a vision for integrating high-levels of sustainability into their projects, we bring unrivalled technical expertise and a portfolio of best practise. We’re extremely proud to say that our contribution can help win awards, too. The Stirling Prize 2019 win for Mikhail Riches’ Goldsmith Street project was noted for its PassivHaus aspect – our incredible team lead the M&E design.

Doves Press typeface

A word on our type

The curious amongst you will have spotted our unusual choice of font for our headings. It’s called Doves. A beautiful type recreated from a 1900 design by T. J. Cobden-Sanderson, in partnership with Emery Walker, in London.

For many years, it was thought Doves had been lost forever. A disagreement between the two men led to tonnes of lead type being thrown into The Thames. Thankfully, 150 metal pieces of type were recovered in 2014 and re-created by enthusiast Robert Green.

For us, this tale continues to inspire and fascinate us. It offers proof that even when all seems lost, there are people – like Robert Green – who will go to any lengths to achieve a positive outcome. It’s a value we share on our own projects.
