About the session

A new two-hour online training session from The Green Register, highlighting the important changes to the Building Regulations that came into force in June 2022.

Ian Mawditt of building performance specialists, Four Walls, will provide an overview with a focus on homes for the changes to Part L (Energy Efficiency) and Part F (Ventilation). We'll also be joined by Joel Callow, Beyond Carbon, who'll discuss overheating prevention (Part O).

This live and interactive training session will have Q&A breaks to allow participants to ask questions of the speakers.

About the Speakers

Joel Callow, Beyond Carbon

After a brief dalliance with nuclear fusion convinced him that renewable energy was definitely our best bet, Joel began his career in low energy building design by studying for a PhD in natural daylight in buildings at the School of the Built Environment, University of Nottingham.

Since then, Joel has worked as a building physics and sustainability champion in a number of leading consulting design practices and across a wide range of construction sectors, including health, education and residential. He enjoys working in close partnership with architects and clients, creatively shaping buildings and places for best environmental performance, climate resilience and highest human health and wellbeing over the long term.

As Founder and Director at Beyond Carbon, he leads the business with thought-leadership in all aspects of building sustainability, including a focus on addressing climate change and human health through beyond net zero carbon buildings, the Passivhaus Standard and natural daylight. He is never happier than when shaping building envelopes and elevations for best natural light, or poring over a thermal bridging detail to ensure best comfort and energy performance.

Joel is passionate about enabling beautiful, person-flourishing architecture at the same time as tackling the climate and ecological emergency – the pressing issue of our time. Joel has been working on reducing his personal carbon footprint for 20 years and is an enthusiastic electric car owner.

He thinks that Building Physics is great fun and may be one of the most under-rated career choices ever.
