Tobias John

ESD & Daylight Consultant

Tobias is another of our resident energy rating aficionados, with a penchant for tricky energy ratings and daylight assessments. He loves getting good results for our clients, even on curly designs in difficult climate zones. This is especially the case for building designs which feature a large amount of glazing, which can make it notoriously difficult to achieve a 6 star rating. Toby has his Certificate IV in NatHERS Assessment and is a Basix Assessor.

Toby's work also includes digital modelling of developments and/or individual rooms to then conduct daylight assessments or thermal modelling for BCA Part JV3 compliance. The results of these assessments are then included in our ESD, BESS, Daylight Assessment or BCA Section J compliance reports.
