DB3 Building Services Engineering
DB3 Building Services Engineering
We bring together mechanical, electrical and public health engineering expertise to design the systems that keep buildings performing and create comfortable, well considered environments for the people who use them.
Our building services engineers cover every core discipline, shaping and delivering the infrastructure behind ventilation, heating and cooling, lighting and the essential services that allow buildings to operate effectively.

Mechanical Design
Mechanical Design
Well designed mechanical building services bring a building to life. They underpin how spaces perform day to day, ensuring systems operate reliably and support the needs of the people who use them.
At DB3, we draw on practical experience to design mechanical systems that allow buildings to live and breathe as part of the wider design. Our expertise covers a broad range of mechanical building services, including:
Electrical Design
Electrical Design
Good electrical design is fundamental to how a building works. It supports safety, resilience and day to day performance.
We deliver bespoke electrical building services design across all project stages, including:
We also deliver detailed electrical design across a wide range of systems, including:

FAQs
FAQs
Can you help decarbonise existing buildings?
Yes. Decarbonising existing buildings is a key part of our work. We undertake condition surveys and technical reviews to identify practical solutions such as plant upgrades, improved controls and phased replacement strategies that reduce carbon while minimising disruption.
Our design and MEP teams can also provide a tailored energy and carbon reduction plan, ensuring your investment is aligned with funding opportunities and long-term sustainability goals
Can you support projects across all RIBA stages?
Yes. Our building services engineers provide support across all RIBA Plan of Work stages, from early feasibility, condition survey, asset reporting and technical advice through detailed design, dynamic simulation, tender support and on site delivery.
What sectors do you work in?
We work across a wide range of sectors, including commercial, leisure, hospitality, industrial, retail education and Energy. You can see our full list of sectors here.
What building services interventions deliver the quickest carbon savings?
The fastest carbon reductions are usually achieved by improving how existing systems operate rather than replacing them outright. Controls optimisation, BMS upgrades, re commissioning and targeted lighting improvements can reduce energy use quickly with minimal disruption. Larger carbon savings can follow from plant replacement or electrification, but these typically require longer programmes and higher capital investment.
How do you measure the success of a building services upgrade?
Success is assessed by comparing post upgrade performance against agreed baselines. Energy and carbon data, system reliability and feedback from building users all provide valuable insight. Post occupancy evaluation is essential to confirm that performance improvements are being realised in practice, not just in design intent.
