Application requirements
For office spaces, user satisfaction and productivity depend on indoor climate conditions and their control. The role of office work is changing and requires new thinking in space design. Here, the focus is on the balance between interaction and autonomy.

The trend is away from the highly structured hive (production line) and cell (quiet individual units) toward dens (noisy open spaces) and clubs (variety inf work areas). These spaces are supported with shared spaces-' touchdown facilities' - where workers share their silent knowledge (source: Flexibility Ltd., UK). As a result, users appreciate the availability of good indoor climate conditions in all usage situations. That requires flexibility from the HVAC systems.

Office-spaces have high cooling requirements, low humidity loads and moderate ventilation demands. In addition, users have different personal preferences in terms of thermal conditions.

Optimal solution
Halton office solutions based on chilled beam systems offer high user satisfaction by providing optimal conditions, in all seasons -and by enabling conditions to be individually adjustable also in an open-plan office. Chilled beam features enable the desired overall thermal conditions to be maintained by continuously controlling cooling and heating capacities, through the Halton control system. Local adjustments are made by Halton Velocity Control, and optimal air quality is achieved by adjusting the primary air flow rate ( 1.5 - 6 l/s/ m²) with Halton Air Quality control.

Halton chilled beams have in-built flexibility for fast and cost efficient room layout changes. An open-plan office can be easily changed into a meeting room or an office room, or vice versa. Primary air flow rate adjustment is performed via the Halton Air Quality control system, and velocity conditions are adjusted by Halton Velocity Control -e.g., in cases where a partition wall is located near the chilled beam. The cooling and heating capacity of a beam can also be reset without influencing the operation of other beams, via Halton Velocity Control or a combination valve. 

The solution is based on a chilled beam system, a very competitive option in terms of life cycle performance. Lower air and water flow rates reduce investment costs while efficient beams reduce energy consumption. Also, system flexibility reduces churn costs.
 
Chilled beams combining ventilation, cooling and heating - and, if desired, other building services - are available to match the interior design of the space. They can be installed in a suspended ceiling or exposed, and also the appearance of the units can be tailored to suit the interior.
