The Benefits of UFAC – AET Flexible Space

The Benefits of UFAC

Using the plenum beneath a raised access floor as the ventilation zone and adopting Under Floor Air Conditioning offers a number of benefits at all stages of building construction and operation creating comfortable adaptable workspace

Height Saving diagram

> choose from zonal air conditioning systems to suit new build and refurbishment projects

> experience simple design and application with pre-engineered and modular equipment

> minimise the cost of change and maintenance with easy access and reliable components

> increase rentability by demonstrating operational advantages for occupiers

> maximise potential integration of on-site renewable technologies


Architects can

  • maximise design freedom in new build construction, integrating natural ventilation and unique features
  • retain historical and distinctive architectural features in older buildings by eliminating the ceiling based services
  • overcome planning constraints by reducing new building heights, or by preserving listed features
  • flexibility to satisfy all project requirements – easily cater for multiple office layouts and configurations

Engineers can

  • upgrade old heated only buildings to fully air conditioned status
  • achieve a high level of building services flexibility and cater to multiple tenant requirements
  • remove all mechanical services from high level, removing the false ceiling and increase headroom
  • reduce total construction time and costs with simple design and application of services

Developers can

  • experience height saving advantages of 10-18% reported through the absence of of ceiling based ventilation zone
  • build 10 floors and get 1 free, increase headroom or overcome height restricted planning constraints
  • reduce total construction costs by up to 7% through building height savings
  • enjoy reduced costs of materials and trade activities through ease of installation at floor level

Investors can

  • reduce investment costs for increased profitability
  • secure investments by avoiding early building obsolescence
  • enjoy earlier occupation and revenue through faster construction time and easy fit out
  • gain through tax advantages in the form of capital allowances gained by the re-classification of raised floor

Occupants can

  • enjoy a user friendly system with personal environmental control for temperature and fan speed adjustment
  • experience quiet, low noise operation for optimum working conditions; additional acoustic barriers and attenuators are easily integrated
  • benefit from effective air distribution and controlled air velocity with no noticeable draughts and thorough mixing of the air
  • enjoy high indoor air quality exceeding ASHRAE standards, resulting in clean and healthy environments and enhanced productivity
  • experience a flexible functional air conditioning system that will adapt to future work place requirements

Operators can

  • benefit from easy cleaning and maintenance, with up to 30% reduction in facilities related operating costs reported
  • maximise energy efficiency with low pressure operation, zonal thermal management and restricted electrical heating
  • reduce disruption and costs of change, with the potential to reconfigure TEN times faster than traditional air conditioning systems
  • easily integrate with most major Building Management Systems (BMS) for easy remote monitoring and control
  • experience up to 200W/sq m cooling load performance with low temperature gradient for optimum staff comfort
