Net zero technical analyst

I drive continual improvement of the innovative Energiesprong approach (especially the comfort plan and technical solutions) by aiding our projects to meet or exceed(!) their performance targets and deliver “people first” retrofit.

What I do at Energiesprong UK

As an engineer, I thrive on understanding how things work and so I have specialised in Building Performance Evaluation; using measurement and monitoring techniques to explore and explain how our homes and their users operate.  

Day-to-day, I lead our compact but talented and diverse team on technical design and performance measurement. I work closely with our Solution Providers to deliver the optimal solutions and achieve the performance guarantee and Energiesprong targets.  

I also take a special focus on occupant satisfaction and the importance of people in housing! After all, people are the best sensor of building performance we have. They’re just uncalibrated…

What I did before Energiesprong UK

My journey started with my PhD research focused on the contribution of user behaviours to building performance (in conjunction with Buro Happold Engineers and The University of Bristol). Subsequently, I worked with Willmott Dixon Energy Services, pioneering performance-feedback approaches, in particular on their wide-scale social housing retrofit schemes.

In 2019, I established my own building performance consultancy, SOAP Retrofit Ltd, to continue championing real-world measurement techniques and developing science-based retrofit approaches. The fit with the Energiesprong UK team to lead on performance measurement and technical design was obvious!  

I have also co-authored the British Standard on Building Performance Evaluation (BS40101:2022), am a steering committee member for PAS 2035, and am a Mentor for The Retrofit Academy.  

My biggest achievement

Many moons ago, I cycled solo through Patagonia, exploring the rugged terrain, beautiful landscape, and meeting many wonderful locals along the way. It took me aback how kind and willing to help everyone was regardless of background or status; frequently offering me accommodation and warm food in their homes (no matter how ramshackle).  

Home is definitely where the heart is, and it catalysed my work to protect that principle for us back in the UK (through retrofit).
