Annex A
(normative)
Additional requirements for multi-tenant buildings
A.1 INTRODUCTION
Annexes A and B focus on the pathways and spaces that are common to multi-tenant
buildings and campuses.
Telecommunications pathways and spaces in multi-tenant buildings are challenged by the
phased nature of their use. After the building is constructed and the first group of tenants
moves in, the tenant’s telecommunications needs may immediately cause modifications to the
building. Over a span of years, as tenants cycle through the building, evolving tenant needs
will oblige the owner/agent of the building to adapt its installations to these demands.
Multi-tenant commercial office and residential buildings have life cycles that mirror that of
single-tenant buildings. Many buildings are over 100 years old. Over time, these older
buildings have become severely challenged to support escalating demands on their pathways
and spaces as a result of tenants’ ever-increasing needs for telecommunications connectivity.
Figure A.1 illustrates a representative model for the various functional elements that comprise
multi-tenant pathways and spaces for a building. This is not intended to be an all-inclusive
representation. It depicts the relationship between the elements and how they are configured
to create a total system. Table A.1 provides a summary of the telecommunications spaces.
Elements of multi-tenant spaces include, but are not limited to,
• entrance room,
• access provider space,
• service provider space,
• common equipment room and
• common telecommunications room.

A.2 Entrance facilities
A.2.1 Entrance location considerations
Consideration should be given to facility, occupants’ and users’ telecommunications wireline
and wireless connectivity needs. If access to both wireline and wireless services is required,
then the entrance facilities may require adjustment in size, quantity and location. Mechanical
fixtures (e.g., piping, ductwork, pneumatic tubing) not related to the support of the entrance
facility should not be installed in, pass through, or enter the telecommunications entrance
facility.
A.2.2 Telecommunications service entrance pathway
Telecommunications service entrance pathways shall be specified to support the initial and
forecasted telecommunications needs including the total building area served and wireline
and wireless tenant connectivity requirements. The forecasted telecommunications needs
shall be agreed upon between the building owner and the designer. Accommodations should
be made for multiple service entrance points to support multiple access providers.
A.2.3 Access
Access to the entrance room shall be controlled by the primary or secondary responsible
organization (see table 1). Signage, if used, should be developed within the security plan of
the building.
A.2.4 Wireless
A.2.4.1 Line of sight
Wireless transmission/reception device placement is critical to its performance. Obstructions
to a wireless transmission/reception device function can take many forms including radio
frequencies, electrical and physical objects. Obstructions may be on the same platform, on an
adjoining building or be located some distance away. Wireless transmission/reception devices
shall be in line of sight with its target system if required by the employed technology. Certain
systems will not function properly if the wireless transmission/reception device’s line of sight
is obstructed.
A.2.4.2 Cable pathways
Cable pathways from tower-mounted wireless transmission/reception devices should be
consolidated where possible on the tower and remain consolidated along their route to the
access provider space. The most direct route between the wireless transmission/reception
device and the entrance facility should be followed. To protect cables from environmental
damage and isolate cables from pedestrian traffic, they should be placed inside conduit or in
cable tray, or be otherwise secured from physical damage.

18010 Amend. 1© ISO/IEC:2005(E) – 11 –
A.2.4.3 Location
Depending upon function and site conditions, wireless service transmission/reception spaces
may be located at the building’s upper rooftop, outside walls or on lower roof setbacks.
Wireless service transmission/reception points may also be located inside the building.
Wherever possible, wall-mounted wireless transmission/reception device support structures
should be mounted at a minimum of 2 m above surfaces where foot traffic may occur.
A.2.4.4 Support structures
A.2.4.4.1 General
A structural analysis shall be carried out by a relevant specialist to aid in the design and
placement of wireless transmission/reception device support structures.
A.2.4.4.2 Towers
Where the location or height of the building makes it a desirable wireless transmission/
reception device site, consideration should be given to installation of a tower on top of the
building. Towers are desirable because they allow efficient use of limited rooftop space, and
offer significant flexibility regarding space planning. Multiple access providers and other users
may share space on a single tower.
A.2.4.4.3 Non-penetrating wireless transmission/reception device mounts
Wireless transmission/reception devices that are of limited weight and size may be installed
on mounts, which are not fastened to the building structural members. These types of wireless
transmission/reception device mounts are often referred to as sled mounts, ballast mounts or
non-penetrating wireless transmission/reception device mounts. These mounts remain
secured to the rooftop by their own weight plus addition of dead weights to keep the wireless
transmission/reception device in place. The amount of weight (ballast) required is calculated
with consideration given to loading created by wind and ice build-up on the wireless
transmission/reception device and supporting system. In some cases, these mounts are
tethered for increased stability. Local regulations may provide specific requirements that have
to be observed. The building owner has to be consulted for permission to add load to the roof.
A.2.4.4.4 Penetrating wireless transmission/reception device mounts
Wireless transmission/reception device mounting systems that penetrate either the rooftop or
walls of a building are commonly employed. The primary considerations with such systems
are the loading that the system places on the structure and waterproofing of any penetration
points.
A.2.4.5 Design considerations
Electrical service shall be sized to support functions that include, but are not limited to
antenna lighting, de-icing and motor-operated functions where required. Where mandated by
regulatory code, automatic switchover to standby power shall be provided. Sizing of the
electrical service shall be carried out by a relevant specialist.
A.3 Access provider spaces and service provider spaces
A.3.1 General
Access to the access provider spaces and service provider spaces shall be controlled by the
primary or secondary responsible organization (see table 1). Common approaches include
lockable cabinets and caged spaces.
---------------------- Page: 11 ----------------------

A.3.2 Location
A.3.2.1 General
Access provider spaces and service provider spaces should be in close proximity to the
common equipment room (CER). The access provider and service provider spaces should be
selected so that the area may be expanded. Access provider spaces and service provider
spaces shall be configured so that each can be accessed through common-use corridors.
Wireless access provider spaces should be located as close as practical to the wireless
transmission/reception devices to which they are connected.
A.3.2.2 Electromagnetic interference
Access provider and service provider spaces shall be located away from sources of
electromagnetic interference. Examples of such noise sources include electrical power supply
transformers, motors and generators, x-ray equipment, radio or radar transmitter and
induction sealing devices.
A.3.3 Pathways
Adequate cable pathway should be provided from access provider spaces to the CER, from
service provider spaces to the CER, and from access provider spaces to service provider
spaces.
A.3.4 Design
A.3.4.1 Architectural considerations
A.3.4.1.1 Partitions
Where access providers and service providers share space, individual spaces should be
segregated by means of partitions. Partitions may be comprised of wire mesh or architectural
assemblies.
A.3.4.1.2 Mounting of equipment
Adequate provision shall be made for mounting of equipment.
A.3.4.1.3 Ceiling height
The height between the finished floor and the lowest point of the ceiling shall be a minimum of
2,2 m. For additional considerations, see recommendation in B.1.1.
A.3.4.1.4 Treatment
Floors, walls and ceiling should be treated to eliminate dust. Finishes should be light in colour
to enhance room lighting. Consideration should be given to application of floor covering
comprised of anti-static material.
A.3.4.1.5 Lighting
Lighting shall be a minimum of 500 lx measured 1 m above the finished floor, mounted 2,2 m
minimum above the finished floor. For additional considerations, see recommendation in B.1.3
NOTE - Lighting fixtures should not be powered from the same electrical distribution panel as the
telecommunications equipment in the access provider space or service provider space. Dimmer switches should
not be used and emergency lighting and signs should be properly placed in such a way that an absence of primary
lighting will not hamper emergency exit.

A.3.4.1.6 Suspended ceiling
Suspended ceiling should not be provided within either the access provider space or within
the service provider space. In such cases where fireproofing may be sprayed onto the
exposed ceiling, the fireproofing should be treated to mitigate airborne dust.
A.3.4.1.7 Door
Doors shall be a minimum of 0,65 m wide and 1,8 m high, without doorsill, hinged to open
outward or slide side-to-side, or be removable. The door shall be fitted with a lock.
Consideration should be given to using double doors with removable centre-post. For
additional considerations, see recommendation in B.1.4.
A.3.4.1.8 Floor loading
Access provider spaces and service provider spaces shall be located on floor areas designed
with an appropriate floor loading. Concentrated floor loads frequently reach and exceed
5,75 kPa and floor-loading capacity shall be designed accordingly. A relevant specialist shall
verify that concentrations of proposed equipment do not exceed the floor-loading limit.
A.3.4.1.9 Signage
Signage, if used, should be developed within the security plan of the building.
When wireless access provider spaces and service provider spaces are employed and
wherever exposure to radio frequency electromagnetic fields may cause harm to personnel,
hazard-warning signs should be posted.
A.3.4.1.10 Seismic considerations
In areas with significant risk of seismic activity, installation practices shall ensure continuity of
telecommunications services under seismic stresses.
A.3.4.2 Environmental considerations
A.3.4.2.1 Heating, ventilation and air conditioning (HVAC)
A.3.4.2.1.1 General
Access provider and service provider equipment is often designed to operate in extreme
environmental conditions such as temperature. Actual air handling requirements should be
calculated based on potential heating and cooling demand associated with equipment which
may be present in the access provider and service provider space.
A.3.4.2.1.2 Continuous operation
If deployed, HVAC shall be provided on a 24 hours-per-day, 365 days-per-year basis. If the
building system cannot assure continuous operation for large equipment applications, then a
stand-alone unit shall be provided for access provider and service provider spaces.
A.3.4.2.1.3 Standby operation
If a standby power source is available in the building, consideration should be given to also
connecting the HVAC system serving the telecommunications access provider space and
service provider space to the standby supply.

Access and service provider space temperature and humidity shall provide for continuous
operation of the installed active equipment. Humidifying and dehumidifying equipment may be
required depending upon local environmental conditions.
A.3.4.2.1.5 Positive pressure
A positive pressure differential with respect to surrounding areas should be provided.
A.3.4.2.2 Batteries
If batteries are used for backup power, adequate ventilation shall be provided.
A.3.4.2.3 Vibration
Mechanical vibration coupled to equipment or the cabling infrastructure can lead to service
failures over time. A common example of this type of failure would be loosened connections.
Potential vibration within the building will exist and will be conveyed to the access and service
provider spaces via the building structure. In these cases, a relevant specialist should be
consulted to design in safeguards against excessive access provider space and service
provider space vibration.
A.3.4.2.4 Other mechanical fixtures
Mechanical (e.g., piping, ductwork, pneumatic tubing, etc.) fixtures not related to the support
of the access provider space and service provider space should not be installed in, pass
