Services
Mechanical Design
Our mechanical design services cover heating, ventilation, and air conditioning systems tailored to building requirements. We specialise in low-carbon solutions incorporating heat recovery and renewable technologies. Projects include detailed load calculations, equipment specification, and compliance with current regulations.
Electrical Design
Comprehensive electrical design services for commercial and residential developments. Our work includes lighting schemes, power distribution, and emergency systems. We ensure compliance with BS 7671 and produce detailed drawings and specifications for construction teams.
Thermal Modelling
Using IES VE software, we perform dynamic thermal modelling to meet TM59 and BB101 standards. Our analysis optimises building performance, prevents overheating, and ensures compliance with Part O regulations through detailed 3D simulations.
Energy Assessment
Registered Low Carbon Consultants provide SAP 10 and SBEM calculations for Part L compliance. We produce Energy Performance Certificates and develop strategies to achieve 10-20% carbon reductions beyond regulatory requirements.
Utility Applications
We manage utility connections for gas, electricity, water, and telecoms through statutory authorities. Our services cover new supplies, diversions, and upgrades, ensuring infrastructure capacity matches development needs while complying with network standards.
