Their purpose – celebrating life in its broadest sense – underpins how they operate at work, at home and within their communities, with performance and purpose always working hand in hand.

Project Requirement

Diageo required a full mechanical services installation for a new-build transportation office which included:

  • Open-plan office spaces
  • Cellular offices
  • New-build welfare facilities

The client specification called for:

  • Heat recovery VRF air conditioning
  • Total Heat Exchange (THE) ventilation unitsproviding filtered fresh air
  • Centralised control interface

7-day timeclock scheduling for energy management

Spectra Energy Group Delivery Spectra Energy Group was appointed as the specialist mechanical subcontractor, delivering the full mechanical package. The works were managed by our in-house SMSTS project engineers supported by on-site SSSTS engineers, with all activity carried out under CDM regulations. Design & Technical Scope
  • Detailed initial design survey of the new-build structure
  • Full design and build mechanical drawings
  • System selection and technical specification
  • Coordination with all trades and PC main contractor
  • Construction of a bespoke plant area for external condensers
VRF & Ventilation Installation Spectra designed and installed:
  • 2 No. Samsung heat recovery VRF systems
  • External condensing units mounted on a Big Foot frame system, complete with fire bat protection and sealed penetrations
  • Internal fan coil units comprising:
    • 600 x 600 4-way blow cassette units
    • Samsung Wind-Free wall-mounted FCUs
  • Total Heat Exchange ventilation units, each delivering 12 l/s per personof filtered fresh air
Controls & Energy Management
  • Individual room controllers for each cellular office with ±3°C adjustment from a setpoint of 21°C
  • Samsung central controllerwith:
    • 7-day scheduling
    • Automated stop signals to prevent unnecessary operation
    • Integrated control of both VRF and THE systems
This ensured efficient operation and reduced energy consumption by preventing out-of-hours running. Internal fan coils consisted of 4-way blow cassette 600m2, wall mounted wind free FCU, full ventilation through total heat exchange units each providing 12l/s per person of filtered fresh air. Each office with its own local room remote controller for local mode settings cooling / heating + or – 3oC from set temperature 21oC. In addition, we installed a Samsung Central controller with 7-day time clock facility, inputting 7 day a week time clock schedules and stop signals for the client, to eliminate the need for the air conditioning and ventilation plant to be operational when not required, this saving energy.
