Linking Ahrend Comfort Workstation with Strukton PULSE can improve comfort as well as achieve considerable energy savings.

For this pilot, two independent innovations, i.e. Strukton PULSE and the Ahrend Comfort Workstation, are linked together. The comfort experience and energy consumption of the comfort workstation are measured and made visible in PULSE. With great results! In this successful pilot, Strukton Worksphere and Ahrend demonstrate that this link can improve the personal comfort experience as well as achieve considerable energy savings.

10% saved on energy consumption in the building
The pilot, which lasted over six months, took place in a sustainable building with 'BREEAM-NL In-Use' certification. In this building, the workplace and area conditions were measured digitally 24/7 and recorded in the digital platform Strukton PULSE. The pilot resulted in over 10% savings on energy consumption. In the longer term, real estate owners will benefit from an easier installation concept in revitalisation. Furthermore, savings can be made on maintenance and replacement maintenance of the installations in the building.

Improved comfort
The pilot shows that people rate the comfort of the workplace better when the climate can be individually adjusted. The table below shows that when the indoor temperature remains the same, user satisfaction (comfort) can rise to 100% when the Comfort Workstation is installed. Even when the indoor temperature is reduced (for energy savings), 94% of users still rate the indoor climate as acceptable, higher than when no Comfort Workplaces are installed.

For employees and building owners
Building owners can save energy and costs by making the climate in buildings adjustable at workstation level through personal heating and cooling. Employees appreciate the ability to adjust the workstation totally to their personal preferences. This has the favourable effect of boosting productivity and reducing absenteeism.

Research method
A practical arrangement was chosen, after the Ahrend Comfort Workstations previously had very positive results in a lab arrangement at TNO. To measure the energy consumption of the Comfort Workstation, the pilot area was set at a fixed basic temperature. Gradually the room temperature was raised (in summer) and lowered (in winter) to determine how much energy saving could be achieved without reducing personal comfort at the workstation. To achieve a better level of comfort, the users could additionally heat or cool their workstation whilst the room temperature stayed the same. The energy consumption required for this was measured and recorded using the PULSE software platform. Analysis software was used to compare the total energy consumption (for the whole building) with the energy consumption without the Comfort Workstation. Furthermore, daily surveys were used to measure how the users experienced the comfort level. We could thus identify the comfort experience of these innovative workstations in different conditions. The survey results were then compared with and without the Comfort Workstation.
