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.

Working with DB3

Working with DB3

With extensive experience in building services engineering, we add value at every stage of a project, from early technical guidance to on site delivery.

Our team provides practical, delivery focused support across a wide range of building services activities, including:

  • Condition surveys and technical reports
  • Preparation and supervision of maintenance contracts
  • Liaison with local supply authorities
  • Tender analysis and on site cost control
  • Production of coordinated specifications and drawings from project inception through to construction, aligned with the RIBA Plan of Work

From the outset, we take a consultative approach, working closely with clients to provide clear, staged advice that supports confident decision making. We can support you with:

  • Procurement route advice and options appraisal
  • Review of proposals, with value engineering input
  • Applications and enquiries for new supplies, increased demands and service diversions

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:

  • Above ground drainage
  • Public health systems, including hot and cold water supplies
  • Sustainable water reclamation solutions
  • Mechanical and natural ventilation systems
  • Air conditioning and refrigeration systems
  • Specialist piped services, such as compressed air, steam and medical gases
  • District heating and cooling systems
  • Heating systems
  • Integration of alternative and renewable technologies, including ground and air source heat pumps, biomass systems and tri generation chillers
  • Total building management systems and automatic controls for building services

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:

  • Condition surveys and technical reports
  • Preparation and supervision of maintenance contracts
  • Liaison with local supply authorities
  • Tender analysis and on site cost control
  • Design of electrical installations in line with BS 7671 and relevant statutory and British and European standards
  • Design of backup power systems, including generators and UPS
  • Production of specifications and drawings from project inception through to construction, aligned with the RIBA Plan of Work

We also deliver detailed electrical design across a wide range of systems, including:

  • Incoming electrical distribution from private or public networks
  • Sub mains distribution, including discrimination and protection studies
  • Small power systems
  • General lighting and lighting controls
  • Emergency lighting
  • Access control, security and CCTV systems
  • Fire alarm and refuge systems
  • Data and communications systems
  • Public address and audio visual systems
  • Lightning protection systems

Sustainable Design Services

Sustainable Design Services

DB3 are accredited to provide energy and carbon emission calculations, certifications and compliance reporting for new and existing buildings.

We are registered Low Carbon Consultants and Low Carbon Energy Assessors through the UK Government accredited CIBSE Certification Register.

Our in-house team supports project teams with a practical, compliant and performance led approach, including:

  • Renewable and sustainable technology reporting aligned with Part L2 and BREEAM
  • Dynamic simulation modelling and thermal modelling for energy, carbon and overheating analysis
  • BRUKL outputs and iSBEM calculations for Part L compliance
  • Energy Performance Certificates and Land Registry lodgement
  • Sector specific compliance and specialist energy reports
  • For existing buildings, we also provide health check reports benchmarking building services and fabric performance and identifying improvement opportunities.

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.
