In the evolving landscape of high-performance building design, understanding the movement of moisture and heat through building envelopes is critical to ensuring long-term durability, comfort, and compliance.  We offer advanced hygrothermal performance assessments using industry-leading WUFI® software, enabling our clients to evaluate the performance of walls, roofs, and complex building elements under realistic, climate-dependent conditions. 


Thermal bridging, or the localized increase in heat transfer due to geometry or material transitions, can significantly undermine the energy efficiency of a building and increase the risk of condensation and mould. We offer advanced 2D and 3D thermal bridge modelling services, helping architects, designers, and manufacturers identify, analyse, and resolve problematic junctions in both new-build and retrofit scenarios. 



We provide expert Passivhaus consultancy and PHPP modelling services to support the design, construction, and certification of ultra-low energy buildings across the UK and Europe. Whether you're embarking on a new-build, EnerPHit retrofit, or generally a project following the Passivhaus principles, we guide you through a performance-first design process rooted in precision, collaboration, and compliance.
