For the full range of building services, including heating, ventilation and air conditioning (HVAC), domestic water services, drainage, LV power, lighting, fire alarms, security, access control and lightning protection.


Laboratory services include the above general systems, but introduce ventilation strategies for control of containment, fume handling, fumigation, piped gasses and special waste.

We have experience in the design of Containment level 2 and 3 laboratories, where ventilation strategies for containment of pathogens and associated air filtration and fumigation systems are introduced.


Our experience includes the design of cleanroom services to ISO 7 standard, for secondary pharmaceutical manufacturing, handling and packing finished goods and manufacturing of drug delivery devices.

Ventilation systems include pressure regimes for room cleanliness and cross contamination protection, HEPA filtration for room air quality control and protection of the environment from product release.

Where handling of flammable solvents or explosive risk through airborne powders is an issue, electrical zoning and static earthing requirements are included in the design.


We provide lighting designs which not only achieve correct lux levels, but also the right “feel”.  In order to reduce Carbon footprint, we offer high efficiency lighting solutions, working closely with key manufacturers.  In some cases, as much as 60% of the original energy can be saved by introducing energy efficient and intelligent lighting systems, with realistic pay-back periods. 


Working closely with user groups and process engineers, Cambridge van Leyden are able to help develop the validation related DQ/IQ/OQ/PQ Protocols, Master Plan and schedules and to assist with execution of the Protocols during the design, construction and commissioning phases.

We have strong capabilities in overall project planning and tracking the process from inception to completion.


We can provide Building Performance assessments utilising IES Virtual Environment software, including:


  • UK Building Regulations, SBEM and SAP compliance reports for Part L and F and Section 6 for Scotland

  • UK Energy Performance Certificates (EPC’s) and Display Energy 
    Certificates (DEC’s), 

  • BREEAM, Code for Sustainable Homes energy and daylight credits

  • BRE daylight, sunlight, overshadowing impact studies, in support 
    of planning

  • Energy strategy reports considering zero and low carbon technologies


Apart from the planning, control and detailed tracking of the design process, we are experienced in the specification, site management and strategic planning of projects.
