We offer expert environmental consultancy for buildings from RIBA Stage 1 to 7. This extends from Pre-planning Energy & Sustainability statements, Part L compliance (SAP & SBEM), wellbeing & comfort assessments, dynamic simulation modelling, thermal bridging calculations, daylight & sunlight analysis and CFD modelling to life cycle costing.

We also look at existing buildings providing carbon reduction and energy efficiency advice and help clients to establish a roadmap to Net Zero Carbon by 2050. We have in-house PAS 2035 assessors and co-ordinators with experience in full house retrofit and refurbishment projects with carbon reduction in mind.

By coming on board at an early stage, we are able to identify and integrate the right design solutions from the outset. We help clients reduce construction costs and meet stringent environmental targets, as well as delivering the required reporting and certification.

A team of Chartered Engineers oversees the quality of our work, which is delivered by highly qualified and experienced low carbon consultants, low carbon energy assessors, PAS 2035, PHPP, HQM and BREEAM assessors backed up by our building services engineering team.
