Services
MEP Engineering
Our mechanical, electrical and public health engineering services integrate sustainable design principles with technical precision. We deliver tailored HVAC, power distribution and plumbing solutions that prioritise energy efficiency while maintaining occupant comfort. Our engineers utilise advanced modelling tools to optimise system performance and ensure compliance with building regulations across diverse sectors including heritage, healthcare and education.
Passivhaus Certification
As certified Passivhaus consultants, we implement rigorous building physics principles to achieve ultra-low energy consumption. Our approach combines thermal bridging analysis, airtightness strategies and heat recovery ventilation systems to create buildings that require minimal heating while maintaining exceptional indoor air quality. We guide projects through the certification process while ensuring cost-effective construction methodologies.
Building Physics Analysis
We conduct comprehensive thermal, daylight and acoustic analyses using dynamic simulation tools. Our services include overheating risk assessments, daylight optimisation studies and acoustic performance evaluations that inform design decisions. This scientific approach ensures buildings achieve optimal energy performance while maintaining occupant comfort through precise environmental control.
Specialist Lighting Design
Our lighting design team combines technical expertise with artistic vision to create functional and aesthetically pleasing environments. We provide daylight integration strategies, energy-efficient lighting schemes and bespoke luminaire design across heritage and modern buildings. Our BIM-integrated approach ensures seamless coordination with other building systems while minimising energy consumption.
BIM Implementation
We utilise Building Information Modelling to enhance project coordination and efficiency. Our BIM Level 2 compliant services include 3D modelling, clash detection and COBie data management using AutoDesk Revit and Navisworks. This digital approach improves design accuracy, reduces construction risks and supports long-term facility management through comprehensive asset information models.
