What is M&E Consultancy in Sustainable Design?

Our sustainable M&E consultancy provides the technical roadmap for heating, ventilating, and powering low-carbon buildings. We specify and design the mechanical and electrical systems required to maximise energy efficiency, ensure occupant comfort, and achieve net zero targets without compromising the architectural vision.



Heating, ventilation, and air conditioning (HVAC) design in modern low-energy buildings is changing. Efficient sizing, intelligent routing, and precise design are now fundamental to the successful creation of low-carbon buildings. Aligning with stringent industry standards, such as those set out by the UK Green Building Council, highlights our commitment to robust building services design.

We maintain a completely independent and agnostic approach. We specify the right technologies for your specific project, not what a manufacturer wants to sell.


"True sustainability isn't just about adding solar panels; it's about engineering the fundamental building services to operate as a cohesive, highly efficient ecosystem from day one."



– Doug Johnson, Founder of Mesh Energy

How Does BIM Coordination Improve HVAC Efficiency?

BIM coordination improves HVAC efficiency by allowing engineers to build and test systems virtually before physical construction begins. This process identifies clashes, optimises pipe sizing, and ensures elegant integration with the wider architectural structure, significantly reducing waste and rework on site.



We utilise centralised building physics modelling and building information modelling (BIM) to fully optimise a range of low energy HVAC technologies for any application. Beyond detailed 3D modelling, we issue clear and concise tender specifications. A well-defined specification allows for a hassle-free tender process and ensures more accurate pricing is returned. Following CIBSE guidelines for effective BIM implementation ensures rigorous coordination and helps streamline project delivery.

Why Choose an Independent M&E Consultancy?

Choosing an independent M&E consultancy ensures you receive unbiased, agnostic advice tailored entirely to your project's needs. We are not tied to specific manufacturers, guaranteeing that our sustainable building physics recommendations are driven solely by performance and efficiency metrics.


By engaging an independent consultant early in the design phase, you mitigate risk and secure long-term value. Adhering to the RIBA's principles on the early integration of M&E engineers improves overall building energy performance. We prioritise getting the design Right First Time, avoiding costly retrofits and ensuring your low-carbon goals are met efficiently.
