There are almost as many variations in the applications of technology as there are buildings. Some techniques and systems that we have detailed experience of are listed.

  • Heat pumps: Ground source, air source, water source.
  • Traditional boilers: Gas, oil, solid fuel.
  • Chillers: screw, centrifugal, scroll, reciprocating compressors; air-cooled, water-cooled.
  • Room emitters: FCUs, radiant panels, embedded coils, displacement ventilation, induction units, chilled beams.
  • Passive design: analysis of building thermal mass for peak-lopping; nighttime cooling; stack ventilation.
  • Indoor air quality: CO2 monitoring and control; process LEV for dust, fumes, oil mist, welding; specialist ventilation for kitchens, car parks, hazardous environments.
  • Process gasses: storing and handling of oxidising, combustible and inert; compressed air.
  • Cleanrooms: system and fabric design; pressure regimes.
  • Fire suppression: sprinklers, canopy suppression, dry risers, fire hose reels; smoke ventilation.
  • Rainwater harvesting: economics of collection and storage; options for re-use of rainwater.
  • Swimming pool water treatment.
  • Renewable technologies: solar PV, solar thermal, wind, biomass, ground-coupling/labyrinths.
  • Building automation: integration of systems, structured management of alarms and maintenance processes.
  • LED lighting, lighting controls, addressable lamping.
  • HV/LV generation, resilient infrastructure.
  • Cat 5 and 6 and wireless data networks.
  • Wiring and containment: flexibility versus cost; bus-bars.
  • Security: CCTV, access control, intruder detection.
  • Fire safety: fire alarms, emergency systems.
  • Specialist lighting: external, sports fields, car parks, roadways, theatre.
  • Communications systems: staff call, paging, nurse call, single worker alarms, disabled call-points.
  • Vertical transport: lifts, escalators, hoists.
