Services
Mechanical and electrical design
We provide comprehensive mechanical and electrical design services for new builds and retrofits. Our engineers deliver scalable solutions from concept to construction, incorporating low-carbon technologies and energy-efficient systems. With 3D coordinated designs and clash detection, we ensure optimal performance while meeting budget and timeline requirements.
Building Information Modelling
Our BIM services utilise Revit and Navisworks for enhanced design coordination. We create IFC files and COBie schedules to streamline project delivery. Through Stabicad integration, we perform engineering calculations directly in 3D models, improving accuracy and reducing design freeze risks while adhering to ISO 19650 standards.
Sustainable design
We implement fabric-first approaches combined with passive comfort systems for sustainable outcomes. Our services include thermal comfort studies, daylight analysis, and life cycle assessments. As net-zero specialists, we help clients achieve BREEAM and WELL certifications while meeting Paris Agreement targets.
Net-zero consultancy
Through our zed. partnership, we offer net-zero carbon consultancy. Our experts provide energy modelling, renewable feasibility studies, and carbon reduction strategies. We support clients with Science Based Targets initiative compliance and Paris-Proof building assessments across all project phases.
Building physics modelling
We conduct advanced building physics modelling including TM54 thermal analysis and computational fluid dynamics. Our services cover SAP, EPC, and BRUKL calculations, ensuring compliance with UK regulations while optimising energy efficiency and occupant comfort.
