Design:
The floor, wall and ceiling elements must be made up of special lightweight boards with a unique 3D core structure. These intelligent lightweight boards should weigh just 1/3 of that of a conventional wood-based board material of the same thickness. Furthermore, they should be extremely stable and facilitate very simple electrification and cable routing within the tops.
The office cubes must have GS certification from TÜV.
Ceiling:
Depending on the size of the room, the ceiling of the office cubes should be made up of 1 or 3 lightweight panels. The soundproofed ventilation and lighting are to be assembled in the central technology panel. The slightly suspended lighting should completely cover the ventilation and control unit so that no ventilation slots and sensors are visible.
Floor:
Depending on the room size, the floor must be made up of one to three elements. These must be connected together and levelled out using glides which can be accessed from above (S = 12 x, M = 16 x and L = 24 x). There must be an opening in the foremost floor panels via which the power supply from the building to the office cube can be accessed. Power connection to the office cubes must be based on the plug and play concept. The se:cube floor is a structural element. The height difference must not exceed 75 mm. The resulting difference in height of 75 mm must, if necessary, be compensated for in full using a rubber ramp (available from RO-Flex GmbH).
Glazing:
The office cube system should be fitted with glass panels on one or two sides. Glazing on one side is standard and always refers to the side with the door. With glazing on two sides, the opposite side is also glazed.
The fixed glass panels are to be supplied as 10.76 mm VSG-SI laminated safety glass with an intermediate acoustic foil, so that db 38 RwP is achieved.
Glass manifestation
To ensure the safety when using the office cube system, the DGUV (German Social Accident Insurance) Information 208-014 set down in Workplaces Ordinance Annex no. 1.5 (3) must be taken into account. Therefore, there must be circumferential partial glass manifestation on the glass surfaces at eye level for the office cube (bottom edge 1400 mm from the floor). This must be included in the product as standard, but can be deselected if the customer would like to apply their own foil wrapping.
Doors:
The all-glass doors must be hinged on the left or right on the corner element or positioned in the middle and have an opening angle of around 160°. The door must always open to the outside. The fittings, the lowerable floor seal and handles with the lock case are to be delivered in graphite structure metallic.
There must be a choice of two door versions:
- Standard: 10.76 mm all-glass door (laminated safety glass with an intermediate acoustic foil) with lowerable floor seal
- Optional: with magnetic locking It pulls the door leaf to the seals and thus improves the sound level reduction.
The doors are to be equipped with dummy cylinders and cannot be locked as standard. It must be possible to insert profile cylinders with 56.5 mm backset into the lock case to allow for adaptation to customer-specific locking systems at a later time. This takes place after the assembly of the office cube by the customer.
Exerior walls
The closed walls are to be fitted with upright melamine panels on the outside. They must come in clear white as standard. These panels are to always be matched to the exterior colour of the office cube. These walls must also be optionally equipped with writable whiteboards , thus providing additional usable creative surfaces.
Sound insulation/acoustics:
The sound insulation of the office cube must be so good that the office cubes can be positioned in the middle of an office. Speech intelligibility depends on the ambient noise level in the surrounding space. Carpets and wall absorbers must be used to achieve optimum room acoustics without flutter echoes and low reverberation times. It also depends on the number of closed walls. The fabric-covered wall panels must improve the reverberation time of the office cube, thus leading to better speech intelligibility. The office cube must be subjected to acoustic testing to determine the sound level reduction and reverberation values. Sound level reduction describes the reduction of sound transmission from the inside of the office cube to the outside and vice versa, taking into account the frequencies relevant for speech. Certification according to DIN ISO 11957 (2010) must be available.
The following acoustic fittings are to be provided:
- Standard: Soundproof supply and exhaust air, double-wall construction, acoustically effective interior wall panels, fixed glass elements 10.76 laminated safety glass + 10.76 mm laminated safety all-glass door with an intermediate acoustic foil and lowerable floor seal
- Optional: additional magnetic locking for the door
- As standard acoustically effective panels must be used for panel 1 and 2 (with S only panel 1) on the closed sides to the left and right of the door and fabric-covered panels must be used for panels 3 and 4 (with S only panel 2) in order to achieve low reverberation times and optimal room acoustics without flutter echo and enhance well-being in the room.
Ventilation:
A soundproof ventilation unit must be located in one of the two closed walls next to the door. It creates a negative pressure in the office cube. The fresh air is thus to be drawn in through the also soundproofed air supply in the ceiling above the lighting, drawn through the room and fed into the wall through the ventilation grille at the bottom. The ventilation unit then must convey the stale air at the top of the se:cube back to the outside into the surrounding area. The large cross-sections of the ventilation elements must ensure that the process is quiet and there is no perceivable draught. No ventilation covers must be visible on the outside.
A clearance of 20 cm above the ceiling of the office cube must be sufficient to ensure a good exchange of air in the room.
As a guideline, 35-45 m³/h of fresh air must be taken as the basis for each person. When setting up the ventilation, the comfort mode must be individually tailored and set to the size of the room and the planned interior, including the number of people. The fully automatic control must regulate the fan based on the room temperature and CO2 content of the room air. If the optional membrane switch is selected for manual control, it must also be possible to control the lighting and ventilation individually.
Air exchange rates for the room size, depending on the temperature and CO2 levels:
- Size S: 58-139 l/s corresponds to 210-500 m³/h, air exchange rate: 81-192 rv/h
- Size M: 58-139 l/s corresponds to 210-500 m³/h, air exchange rate: 36-87 rv/h
- Size L: 58-139 l/s corresponds to 210-500 m³/h, air exchange rate: 17-40 rv/h
- The air quality in the cube must be permanently monitored by a CO2 sensor. If the CO² content exceeds 1000 ppm, the ventilation control system must increase the air exchange rate fully automatically. To ensure the safety of the user, when the CO² content reaches 1300 ppm, a visual light signal (brighter and darker main lighting inside) must indicate that the air quality is poor and either the ventilation should be increased or the door should be opened.
The office cube control must be fitted with a run-on time for ventilation which is automatically triggered when the room is exited. The run-on time for ventilation must not be less than 5 minutes to ensure a complete exchange of air and thus guarantee that the room is optimally prepared for subsequent use.
Packaging:
The product must be packaged in reusable containers (Germany) or disposable pallets (abroad) depending on the size and application of the office cubes. Items must be supplied in sections in order to keep the transport volume as small as possible.
Depending on size, the transport volume must not exceed:
- Size S empty: 8 m³ se:cube S with interior 8.5 m³
- Size M empty: 8 m³ se:cube M with interior: 10 m³
- Size L empty: 10 m³ se:cube L with interior: 12.5 m³
