1 CEILING&WALL SYSTEMS Between us, ideas become reality Armstrong Ceiling Systems HEALTH & WELLBEING HEA 01 Visual Comfort HEALTH & WELLBEING HEA 02 Indoor Air Quality HEALTH & WELLBEING HEA 05 Acoustic Performance WASTE WST 01 Construction Waste Management WASTE WST 04 Speculative Floor and Ceiling Finishes MANAGEMENT MAN 04 Stakeholder Participation BREEAM is an environmental assessment method and rating system for buildings. It sets a standard for best practice in sustainable building design, construction and operation and has become one of the most comprehensive and widely recognised measures of a building s environmental performance. A BREEAM assessment uses recognised measures of performance, which are set against established benchmarks, to evaluate a building s specification, design, construction and use. The measures used represent a broad range of categories and criteria from energy to ecology. They include aspects related to energy and water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and management processes. BREEAM uses a straightforward scoring system (credits) which are supported by evidence-based science and research. The following BREEAM credit 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 credits are identified on each page of this document and contain an extract from the BREEAM New Construction Non-Domestic Buildings Technical Manual SD : 2011 setting out the aim of the credit, the assessment criteria, the compliance requirements and how Armstrong can help at both the design and post construction 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.

2 HEALTH & WELLBEING HEA 01 Visual Comfort To ensure daylighting, artificial lighting and occupant controls are considered at the design stage to ensure best practice visual performance and comfort for building occupants. Pre-requisite Daylighting (1-2 credits) - building type dependent Glare control and view out (1-2 credits) building type dependent Internal and external lighting (1 credit) Visual Arts (1 credit) Healthcare building types only Daylighting Compliance Requirements: Relevant building areas meet good practice daylighting criteria. NB: The daylight criteria differ for each building type. They cover daylight factor, uniformity ratio, and also state a proportion of the area of the building required to comply. Internal Lighting Compliance Requirements Illuminance (lux) levels in all internal relevant building areas of the building are specified in accordance with the CIBSE Code for Lighting 2009 and any other relevant industry standard. For areas where computer screens are regularly used, the lighting design complies with CIBSE Lighting Guide 7, 2005 sections 3.3, 4.6, 4.7, 4.8 and 4.9. This gives recommendations highlighting: 1. Limits to the luminance of the luminaires, to avoid screen reflections. (Manufacturers data for the luminaires should be sought to confirm this). 2. For up-lighting, the recommendations refer to the luminance of the lit ceiling rather than the luminaire; a design team calculation is usually required to demonstrate this. 3. Recommendations for direct lighting, ceiling illuminance, and average wall illuminance. Appendix 1 includes the reflectance of the ceiling tiles which is required to calculate the daylight factor and the uniformity ratio. Armstrong range of mineral fibre and metal ceiling tiles achieve high levels of light reflectance. High light reflectance ceilings enhance indirect lighting by improving overall lighting uniformity returning up to 90% of the light back into the space, compared with 75% with standard ceilings*. A light reflectance of 90% and more allows 20% cost savings with indirect lighting, and can yield total building energy savings of up to 11%. Canopies installed in the work place can improve the light reflection over a working space and provide better comfort for the end user. *Energy and Environmental Effects of High Light Reflectance Ceilings: Brinjac Engineering Post Construction Review Appendix 1 includes light reflectance values and can therefore be used for calculations. Detailed technical information will also be provided for the maintenance manual and will be made available to the BREEAM assessor to confirm compliance. 2 Armstrong Ceiling Systems

3 HEALTH & WELLBEING HEA 02 Indoor Air Quality To recognise and encourage a healthy internal environment through the specification and installation of appropriate ventilation, equipment and finishes. Minimising sources of air pollution (3 credits) Potential for natural ventilation (1 credit) Laboratory fume cupboard and containment areas (2 credits) Minimising Sources of Air Pollution Compliance Requirements 2 of the 3 available credits can be achieved by demonstrating compliance with the following: 1. An indoor air quality plan has been produced. 2. All decorative paints and varnishes have met the requirements listed in Table At least five of the eight remaining product categories listed in Table 5-3, have met the testing requirements and emission levels for Volatile Organic Compound (VOC) emissions against the relevant standards. Product European Standard Emission levels for VOC s required Suspended ceiling tiles (Extract from table 5-3) EN 13964:2004 Formaldehyde E1 (Testing req 1) No asbestos. Non-Domestic Buildings Technical Manual. All Armstrong ceiling tiles have low or zero VOC emission levels and therefore can comply with an Indoor Air Quality Plan which commits to using low or zero VOC finishes. All Armstrong tiles have either been tested by a third party and comply with the requirements of EN 13964:2004 unless they are exempt from testing (e.g metal or wooden ceiling tiles). Appendix 1, Armstrong Products Environmental Performance Table provides the results of the tests for each tile. Post Construction Stage Appendix 1 states the emission levels met by each tile. The BREEAM assessor can provide this document to demonstrate compliance. 3 Armstrong Ceiling Systems

4 HEALTH & WELLBEING HEA 05 Acoustic Performance To ensure the buildings acoustic performance including sound insulation meet the appropriate standards for its purpose. 1. A suitably qualified acoustician (see relevant definitions) is appointed by the client at pre-bid/briefing stage of the project to provide early design advice on: a. External sources of noise impacting the chosen site b. Site layout and zoning of the building for good acoustics c. Acoustic requirements for users with special hearing and communication needs, d. Acoustic treatment of different zones and facades. 2. The building meets the acoustic performance standards and testing requirements for the relevant building type and function areas as detailed in Table 5-4. Minimising Sources of Air Pollution Compliance Requirements The compliance requirements for this credit are dependent on the building type. Table 5-4, in the BREEAM assessment manual, sets out the detailed requirements for each building type. Detailed information on the acoustic performance of Armstrong ceiling tiles is available from Appendix 2, Armstrong Products Absorption, Attenuation Comparison Table. 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 absoption and sound attenuation through to control of reverberation times and ambient noise levels. Post Construction Stage The assessor can verify that the correct figures have been used in the acoustician s report by cross referencing the acoustician s report with Appendix 2. 4 Armstrong Ceiling Systems

5 WASTE WST 01 Construction Waste Management To promote resource efficiency via the effective management and reduction of construction waste. Construction resource efficiency (3 credits) Diversion of resources from landfill (1 credit). Construction Resource Efficiency Compliance Requirements Non-hazardous construction waste (excluding demolition and excavation waste) generated by the building s design and construction meets or exceeds the following resource efficiency benchmarks. BREEAM credits Amount of waste generated per 100m 2 (gross internal floor area) m 3 tonnes One credit Two credits Three credits Exemplary Level Diversion of Resources from Landfill Compliance Requirements The following percentages of non-hazardous construction and demolition waste (where applicable) generated by the project have been diverted from landfill: Product Type of waste Volume Tonnage One credit Exemplary level Non demolition 70% 80% Demolition 80% 90% Non demolition 85% 90% Demolition 85% 95% Diversion from landfill includes: 1. Reusing the material on site (in-situ or for new applications) 2. Reusing the material on other sites 3. Salvaging or reclaiming the material for reuse 4. Returning material to the supplier via a take-back scheme 5. Recovery of the material from site by an approved waste management contractor and recycled or sent for energy recovery. Armstrong provide a comprehensive post-consumer mineral fibre ceiling tile take-back scheme covering tiles at the end of their life and off-cuts generated during the instalation process. Accredited professionals and Assessors can use Appendix 1 to identify which tiles are included in the scheme. Full details of the take back scheme are available at Post Construction Review Armstrong can provide BREEAM Accredited Professionals and design teams with verification of weight for inclusion in Site Waste Management Plans. 5 Armstrong Ceiling Systems

6 WASTE WST 04 Speculative Floor and Ceiling Finishes To encourage the specification and fitting of floor and ceiling finishes selected by the building occupant and therefore avoid unnecessary waste of materials. 1. For tenanted areas (where the future occupant is not known), prior to full fit-out works, carpets, other floor finishes and ceiling finishes have been installed in a show area only. 2. In a building developed for a specific occupant, that occupant has selected (or agreed to) the specified floor and ceiling finishes. Compliance Requirements Compliance notes Show area A show area could be either a floor plate or an individual office. However, to award this credit it must be less than 25% of the net lettable floor area. Armstrong s ceiling tiles are not just a finish. They are an integral part of the environmental design of a space, contributing to the acoustic, visual environments and the internal air quality. By providing the end client with information on the environmental credentials of our tiles we ensure that they will be selected. Post Construction Review If the ceiling tiles used to fit out the show area in a speculative office are included in the take back scheme they would be removed by Armstrong post occupancy subject to meeting the schemes terms and conditions. 6 Armstrong Ceiling Systems

7 MANAGEMENT MAN 04 Stakeholder Participation To design, plan and deliver accessible functional and inclusive buildings in consultation with current and future building users and other stakeholders. Consultation (1 credit) Inclusive and accessible design (1 credit) Building user information (1 credit) Post Occupancy Evaluation (POE) and information dissemination (1 credit). Building User Information Compliance Requirements 1. Building User Guides are provided and are appropriate to all users of the building (general users including staff and if applicable residents, as well as the non technical facilities management team/building manager). 2. The Guides cover all functions and uses of the building, ensuring building users are able to use the building effectively. Where relevant, the documents must describe the facilities to be shared and how access to them will be arranged for potential users. 3. Building and site related information is made readily available to all future building users, enabling them to access and use the building, site and local transport infrastructure/amenities effectively. Armstrong provides information relating to the environmental credentials (Appendix 1) of all their ceiling tiles. This gives Accredited Professionals the information they need to demonstrate how the specified ceiling tiles contribute to the overall environmental strategy for the building. This information can be fed into the design team meetings. When specifying Armstrong ceiling tiles the client/developer can be assured that all information required to complete the building user guide will be available for inclusion in the building specification document. This will give the necessary confidence to write the letter of commitment that will be required to gain this credit for a design stage BREEAM assessment. Post Construction Stage Information is available for the assessor to explain how the specified or recommended ceiling tiles contribute to the environmental strategy (including the visual environment, acoustic environment, internal air quality, energy performance) and on how the take back scheme operates. 7 Armstrong Ceiling Systems
