Recently featured in the UK Government’s Low
Carbon Action Plan, Ska Rating is an RICS-led
and owned environmental assessment method,
benchmark and standard for non-domestic fit-outs.
Ska Rating helps landlords and tenants assess fit-out
projects against a set of sustainability good-practice
criteria. It is estimated that 11% of UK construction
spending is on fit-outs and buildings may have 30-40
fit-outs during their lifecycle.
Ska Rating has been developed with designers,
contractors, corporate occupiers, managing agents
and consultants.
The offices scheme consists of 104 individual
good-practice measures covering Energy and
CO2 Emissions, Waste, Water, Materials, Pollution,
Wellbeing and Transport.
The following Ska rating good-practice summary
has been developed by Armstrong Ceiling Systems
to support the design, specification and installation
of Armstrong suspended ceiling systems in a wide
range of buildings.
The relevant good-practice measures are identified on
each page of this document and contain an extract
from the Ska rating manual – Good practice measures
for offices - version 1.1 2011, setting out the aim of
the good-practice measure, the assessment criteria,
the compliance requirements and how Armstrong can
help at both the design, handover and occupancy
stage.
Supporting evidence is contained in Appendix 1,
Armstrong Products – Environmental Performance
Table and Appendix 2, Armstrong Products –
Absorption Attenuation Comparison Table. These
appendices cover the full range of Armstrong
suspended ceiling systems.

■ Suspended Ceilings
M10
Good Practice Measure Rationale:
To reduce the embedded lifetime environmental impacts of
materials that can be estimated using life cycle analysis (LCA).
This measure applies if suspended ceilings are specified,
replaced, refurbished or installed.
Assessment Criteria
All suspended ceiling systems, including frames, and/or
boards, meet at least one of the following criteria:
• Are reused (note: if only tiles are replaced, the frame can
be recorded as reused; the tiles must then meet one of
the criteria below)
• If new, are manufactured with at least 50% recycled
content;
• Are supplied with an environmental product declaration,
written in accordance with ISO 14025 standards
Guidance:
The target for the recycled content of suspended ceilings
is based on WRAP’s stated good practice for mineral fibre
ceiling tiles. WRAP indicate that some ceiling tiles, such as
steel ceiling tiles, are unlikely to meet this target.
HOW ARMSTRONG CAN HELP
Design Stage
Armstrong ceiling tiles have high recycled content
calculated in accordance with ISO 14021:2001 and
consistent with the WRAP “Rules of Thumb” guide.
Environmental Product Declarations are written in
accordance with ISO 14025.
Appendix 1, Armstrong Products Environmental
Performance Table contains the relevant details for
individual products.
Handover and Occupancy Stage
Armstrong can provide EPD’s for Ska Assessors for
inclusion in the site Building User Guide (BUG).

■ Suspended Ceilings
D07
Also reference Ska good practice measures P03 (Reduce C & D
waste sent to landfill), P04 (Increase recycled C & D waste) and D09
(SWMP)
Good Practice Measure Rationale:
A site waste minimisation plan is part of the site waste
management plan (SWMP). All construction projects in
England worth more than £300,000 “must implement a
SWMP”.
Scoping
This measure applies to all fit-outs.
Assessment Criteria
A site waste minimisation plan is prepared prior to site
work, detailing measures to minimise waste generated on
site. The plan must be carried out during the construction
phase.
Guidance:
WRAP’s Design out Waste tool for buildings and NetWaste
tool can be used to populate the WRAP SWMO template
and provides advice on initiatives for reducing waste in
design and construction. Both tools are accessible online
to registered users; registration is free.
HOW ARMSTRONG CAN HELP
Design Stage
Armstrong provide a comprehensive post-consumer
mineral fibre ceiling tile take-back scheme recovering
tiles at the end of their life and off-cuts generated
during the instalation process. These tiles are put
back into the manufacturing process to create new
ceiling tiles as part of the Armstrong Ceiling-2-Ceiling
programme.
Appendix 1, Armstrong Products Environmental
Performance Table identifies which tiles are included
in the scheme. Full details of the take back scheme
are available from our dedicated Recycling Team at
recycleyourceilings@armstrong.com
or by calling 0800 371 849 (UK) or 1800 409 002

■ Reduce ceilings sent to landfill
D13
Also reference Ska good practice measures P03 (Reduce C & D waste
sent to landfill) and P04 (Increase recycled C & D waste)
Good Practice Measure Rationale:
The aim is to reduce the amount of ceiling waste sent to
landfill, which is highly wasteful in terms of energy and
resource use.
Scoping
This measure applies if the removal of existing ceilings
forms part of the fit-out contract or if new ceilings are
being installed.
Assessment Criteria
At least 80% of the waste ceilings are:
• Reused;
• Recycled; or
• Diverted from landfill.
Guidance:

■ Materials Specification
D19
Good Practice Measure Rationale:
The aim is to reduce the environmental impact of the
production, use of, and disposal of building materials.
Scoping
This measure applies if the removal of existing ceilings
forms part of the fit-out contract or if new ceilings are
being installed.
Assessment Criteria
At least 80% of the materials installed are:
• Reused;
• Contain at least 80% recycled or recyclable content
• Have A or A+ in BRE’s The Green Guide or Green Book
• Are supplied with EPD in accordance with ISO 14025.
Guidance:

■ Thermal Comfort assessment
D28
Good Practice Measure Rationale:
Thermal comfort is an important criterion for occupant
wellbeing. The use of thermal modelling at the design stage
of the fit-out should aim to select the HVAC strategies that
provide optimal comfort and minimise overheating risks.
Scoping
This measure applies if HVAC systems are being installed
or replaced.
Assessment Criteria
Thermal comfort modelling to CIBSE AM11 has been
carried out at the design stage; the results of this
modelling are used to select a service strategy to CIBSE
Guide A.
Guidance:
Building energy and environment modelling, Applications
model AM11, CIBSE, 1998.
Environmental design (7th edition), Guide A, CIBSE, 2006.
HOW ARMSTRONG CAN HELP
Design Stage
Armstrong CoolZone, an innovative ceiling solution
that absorps energy during the day and releases it
at night, can be used as part of the HVAC strategy
to improve occupant comfort and reduce the risk
of overheating. TAS software can also model the
performance of CoolZone
Handover and Occupancy Stage
Armstrong can provide a thermal modelling module
for CoolZone to calculate the requirements to
manage overheating, maintain thermal comfort and
reduce energy and running costs.

■ Noise Level Standards
D29
Good Practice Measure Rationale:
Noise is defined as unwanted or harmful sound. Noise is
part of everyday life, but load noise can permanently damage
hearing. Noise can also cause distraction from tasks, making
people more inefficient or inattentive. Central air handling units
(AHUs) are a major source of internal noise. Internal noise
levels need to be considered during design stage.
Scoping
This measure applies if a fresh air handling unit (AHU) is
being installed or replaced.
Assessment Criteria
Criteria recommended by the British Standards Institute
are met. Indoor ambient noise level in unoccupied offices
must fall within the following ranges:
• 35 – 40 dB LAeq, T in meeting rooms
• 40 – 50dB LAeq, T in cellular offices; and
• 45 – 50 dB LAeq, T in open plan offices.
Guidance:
Sound insulation and noise reduction for buildings. Code
of practice, BS 8233:1999, BSI, 1999.
HOW ARMSTRONG CAN HELP
Design Stage
Detailed information on the acoustic performance
of Armstrong ceiling tiles is available from Appendix
2, Armstrong Products Absorption Attenuation
Comparison Table.
Acoustical test reports showing the performance
of our tiles can be provided. Armstrong can also
provide reverberation calculations to determine
which tiles are required.
This information can be used by a suitably qualified
acoustician to demonstrate how the ceiling tiles
contribute to the acoustic perfomance of each
space. Different ceiling tiles are available to
contribute to all aspects of a building’s acoustic
performance, from passive acoustic management
of sound absorption and sound attenuation through
to control of reverberation times and ambient noise
levels.
Handover and Occupancy Stage
Armstrong tiles will help to meet the sound
measurements taken on site by a qualified
acoustician.

■ Lighting Design
D30
Also reference Ska good practice measures D31
(Daylight glare control) and D04 (Daylighting)
Good Practice Measure Rationale:
The visual comfort of office workers is affected by the
levels of illumination on the working surfaces. Different
lux levels are required for different office areas, such as
occupied workspace and corridors. Task based lighting
should ensure maximum visual comfort, while avoiding
over-illumination of spaces where high lighting levels are
not required.
Scoping
This measure applies where general office lighting is being
installed, replaced or modified.
Assessment Criteria
Lighting levels (measured in lux) are designed to meet
those in CIBSE Lighting Guide 7: Office Lighting.
Guidance:
Code for lighting, Part 3- Lighting Design, CIBSE, 2009.
Lighting Guide 7: Office Lighting, CIBSE, 2005.
HOW ARMSTRONG CAN HELP
Design Stage
Armstrong ceiling tiles have a range of light reflectance
properties, which when used in conjunction with the
lighting design, can achieve the required lighting
levels.
Armstrong high light reflectance ceilings can aid
in extending daylighting into the space. A typical
acoustical ceiling reflects just 75% of the light striking
the surface, while a high light reflectance ceiling is
engineered to reflect up to 90% of the light striking
the surface.
Recent independent studies have shown a
10 - 15% daylighting effectiveness increase.
Appendix 1, Armstrong Products Environmental
Performance Table includes the light reflectance of
our ceiling tiles.
