Sustainability Consultancy


The team comprises sustainability specialists from architectural and scientific backgrounds all working with a common goal to produce the  best, most beautiful buildings and places.

By bringing together experts in sustainability from different backgrounds we take advantage of opportunities a less integrated approach might not even find.

Jess Hrivnak

BA Mphil DipArch

Senior Sustainability Consultant

I am passionate about sustainability and design. I enjoy working within a team and with clients to develop creative solutions that have tangible results.

A project works best when a sustainable approach is chosen right from the start. I assist in integrating environmental aims into the design process, helping a project’s sustainability credentials to be truly interwoven.

I’m keen to help clients and designers understand and communicate sustainable design effectively.. As well as holding and facilitating Sustainability Workshops for clients, I’ve written sustainable design guides and generated sustainability key performance indicators for masterplans. I have also written a property selection tool and sustainability design manual for the British Council to help ’green’ their offices all around the world.

Sustainability involves so much more than energy. I’m also interested in looking at environmental footprinting, corporate social responsibility and behaviour change.

Tamsin Tweddell

MSc MA CPhys MInstP

Senior Partner

I lead the Practice’s work on building performance, advocating a Soft Landings approach and encouraging project teams to engage with operational issues from design through to post-occupancy. I am keen to provide operational support to the users and managers to help them get the most out of their building.

My involvement in post-occupancy work began as Project Engineer on the Renewable Energy Systems Headquarters. After delivering the project through design to practical completion, I was able to observe the building in use for two and a half years. Through this experience, I saw first-hand just how much operational use differs from design expectations and how I could help lessen the gap. Here, and again at the Hayward Gallery, I was able to help fine-tune the systems to maximise comfort and minimise running costs.

I have also worked with University College London to investigate the energy performance gap in schools, co-authoring a paper, and I am an active member of the BSRIA Soft Landings User Group.

Sustainability Consultant

'Sustainability can mean a lot of things to a lot of different people.'

One of the things I really enjoy doing is working with clients and other stakeholders to help them understand what it is they want from their project.

The result of that engagement is a client with a clear vision for their project and a design team with the clarity to tailor their response to that vision.

The ability to communicate clearly is central to my role. I favour a visual approach to my work, using drawings, diagrams and infographics to develop ideas and relay them to the client and the design team. It’s an iterative and fluid process.

I have had the opportunity to work on a range of different building types and scales, with the added benefit of working in diverse locations around the world. The unique challenges of cultural buildings are a particular highlight, but I’ve also worked on education, commercial, sports and retail schemes.

Sustainability Consultant

There’s something satisfying about being in a well-conditioned space, where the temperature is just right, the air is fresh, the light-level appropriate.

But the things that make a difference to how a building feels are not immediately obvious to the eye. It’s about having the right systems in place and the processes that support efficient building operation that make the difference.

My background is in psychology, environmental design and architecture and I think this is a potent combination for making better buildings. Design can influence human behaviour, but the complexity and reality of human behaviour should also influence design.

I advise design teams on how they can apply sustainability concepts and methodologies to produce better buildings; buildings that work. BREEAM is one of the useful tools that can help meet this end. When approached in the right spirit as a holistic and robust standard rather than another form of compliance, it provides an excellent framework to ensure that the details that deliver better building survive to the end of the construction process.

Bill Gething

MA Dipl Arch RIBA

Sustainability Consultant

An independent architecture and sustainability consultant working with the Max Fordham Sustainability Team, I specialise in climate change adaptation and thermally upgrading existing buildings.

As an architect at Feilden Clegg Bradley Studios, I spent many years working alongside engineers from Max Fordham. I provide a broader perspective to the Practice’s design approach, while getting involved with projects where my skills add most value.

A Partner at Feilden Clegg Bradley Studios for nearly thirty years, I developed broad experience across masterplanning, bespoke offices, higher education buildings, housing and designing caring communities. I helped deliver many projects contributing to its reputation as leaders in sustainability.

I'm also involved in numerous other projects, including reporting for the UK Technology Strategy Board, working with the Energy Saving Trust and being an external examiner for the Architectural Association Sustainable Environmental Design Masters course.

Hero Bennett


Senior Sustainability Consultant

I help clients to explore, define and achieve their sustainability aspirations. My work helps form excellent sustainable design that is appropriate for users, the site and the wider environment.

My experience gives me a broad understanding of what sustainability issues need to be considered during design. Having taken projects from design to site as an Engineer, I can appreciate some of the practical difficulties in delivering sustainability targets.

Communication throughout the process is key to overcoming these difficulties. I’m trained to facilitate sustainability discussions to set the aspirations and brief, communicate design options and help the team choose effective design strategies.

I also have experience explaining sustainability externally, through both public consultations and in presenting 'The Sustainability Matrix', a communication tool developed by Max Fordham and published in the Architects Journal in 2010. The work is varied; from looking at material selection for a private house to developing a masterplan’s sustainability and energy strategy. I’m interested in it all.

I am also experienced in Passivhaus design.

Anna Foden


Sustainability Assessor

I think we have a responsibility to design and construct buildings sustainably. 

I specialise in helping clients and design teams explore possibilities and make informed decisions about the environmental impacts of their buildings.

Many people on this planet spend the majority of their day indoors, creating a constant cycle of constructing or refurbishing our built environment. We should design and build these spaces to be as comfortable, safe, and resource-efficient as possible. They should also have as minimal an impact on the environment as possible, both during construction and in use. This involves designing to minimise CO2 emissions, water and energy usage,  embodied carbon of materials, and construction waste, as well as enhancing biodiversity and providing occupant amenities. 

The client's aspirations are a good starting point, but understanding how the building will be used - actually engaging with future building occupants as early as possible - is a key element of a successful project.  I help my clients figure out what they want for their building and develop conclusions about what's realistic within their brief and budget. I stay involved throughout the life of the project to help them reach those desired outcomes.

Ingrid Berkeley


Sustainability Consultant

Buildings in the UK account for a huge quantity of carbon dioxide emissions - as high as 45% of our overall output.

Being able to make a positive difference in reducing the built environment’s consumption of natural resources, and to mitigate the impact of climate change, is enormously important to me.

One of the conditions that weighs heavily on a building’s energy performance is complexity. Too often unnecessarily complex designs mean a building performs badly because it’s difficult to operate, and things go wrong. I aspire to simplicity, and I privilege passive design over mechanical intervention.

My role covers many aspects from advising on low carbon techniques for generating energy on site, to carrying out Post Occupancy Evaluations to ensure the building performs as designed. I’m also a Soft Landings champion and joint BREEAM Manager for the Practice.

There are powerful ways we can improve the performance of our buildings and reduce their impact on the planet. I love playing my part in that outcome.
