Susie Diamond MInstP aMCIBSE
Partner

Susie founded Inkling in 2011. Prior to that she led the Building Physics team at Mott MacDonald (previously Fulcrum Consulting).

She has worked on a diverse range of projects providing dynamic thermal modelling expertise to inform the design process in various ways. She has gained particular recognition for her work on assessing overheating risk, and is currently focussed on using modelling tools to predict (and improve) in-use energy performance.

Susie works hard to collaborate with clients, listening closely to what they want to achieve within the usual constraints of planning, legislation and budget. She encourages early, face-to-face discussions about Building Physics; explaining its value as a design tool; informing design decisions and giving guidance on how decisions will impact on thermal comfort and energy performance.

Susie acted as judge for the CIBSE Building Performance awards three years running. She is a lead author on industry guidance including CIBSE TM59: Design methodology for the assessment of overheating risk in homes and CIBSE TM54 Evaluating operational energy use at the design stage (2022). She has contributed to numerous industry groups including LETI, and the CIBSE Resilient Cities group; and written about the industry for a range of media including BBC News, The Guardian and the CIBSE Journal.

Dr Claire Das Bhaumik FCIBSE
Partner

Claire is a Chartered Engineer, a CIBSE Fellow and a member of the NABERS UK Independent Design Review Panel.

She joined Inkling as a partner in 2013 having worked for a number of leading consultancies. She is committed to practising and promoting sustainable building design. She has extensive experience in the use of dynamic simulation software packages for comfort analysis, energy use prediction, HVAC modelling and Building Regulations compliance.

Claire has published a number of peer-reviewed research papers and contributed to various industry publications. Claire has a background in building services engineering and works hard to encourage and facilitate understanding and communication between members of the interdisciplinary design team.

She has also supervised two Knowledge Transfer Partnerships (KTPs) with the University of Strathclyde on behalf of arbnco Ltd, an innovative building technology company based in Glasgow, acts as an independent expert for The European Commission under the Horizon Europe Framework Programme for Research and Innovation (previously Horizon 2020) and is currently leading the London Energy Transformation Initiative (LETI) modelling group subgroup on HVAC modelling.

Marcus Haydon MCIBSE
Associate

Marcus joined Inkling in 2023 after several years of close collaboration as an independent consultant.

He is a strong believer in the value of modelling as a facilitator of good design, advocating that specialists in modelling should have a deep understanding of not only the analysis tool, but also the dynamics of building behaviour and the systems that they contain.

Marcus has a background in building services design, having started out as a project engineer in a building services and environmental engineering consultancy, working on a wide range of projects and gaining experience of MEP systems and dynamic simulation modelling. He went on to become a modelling specialist and in 2015 set up as an independent consultant, looking to bridge the gap between engineering expertise and the understanding of modelling tools.

In recent years Marcus has had a strong focus on overheating risk in buildings, consulting on numerous projects and contributing to the research and guidance produced by the likes of CIBSE and the Future Homes Hub. He also contributed to the production and technical review of LETI’s Operational Modelling Guide, published in 2023, which looks to promote and facilitate the role of detailed building modelling in helping to deliver performance that meets design intent.
