1. INTRODUCTION

1.1.1 Southdowns Environmental Consultants Limited (Southdowns) was commissioned by Arcadis to undertake an environmental noise assessment to assess the site suitability and inform a planning application to London Borough of Hounslow (LBH) for the Demolition of club house and associated car park and Multi-Use Games Area, construction of a new part 2 - part 4 storey secondary school (Use Class D1) with ancillary car parking, cycle parking, Multi-Use Games Area, hard and soft landscaping and associated works, together with improvements to MacFarlane Lane. The site address is 1 MacFarlane Lane, Isleworth, Hounslow, TW7 5PN.

1.1.2 An environmental noise survey has been undertaken to establish the existing noise levels across the site. Sound levels and criteria normally used for the assessment of environmental noise at proposed school sites are presented in the following section of this report. The site and the immediate surrounding area are described under Section 3. Details of the noise surveys and measurements undertaken on site are presented under Section 4. The survey results are given in Section 5 and the noise assessment is addressed in Section 6. Mitigation options are provided in section 7 with the conclusions of this study summarised in Section 8.

1.1.3 This site feasibility noise assessment will be updated with a planning stage noise assessment.

2. SOUND LEVELS AND CRITERIA

2.1 Sound Levels

2.1.1 Sound is measured on a logarithmic scale in decibels (dB) because of the ears’ sensitivity to a wide range of pressure changes. The sound pressure level (SPL) of a signal is denoted by the symbol Lp and defined by the equation Lp = 10 log (p/po)2 where p is the root mean square pressure of the signal and po is the reference sound pressure (2 x 10-5 Pa).

2.1.2 The human auditory system is capable of detecting sounds over a frequency range of approximately 20 Hz to 20 kHz. Because the ear is most sensitive to sounds with frequencies between 1 and 5 kHz, an A-weighting network is used to reflect the differential sensitivity of human hearing to sounds of different frequency. The A-weighted sound pressure level, LpA, is measured on a scale denoted by the metric dB(A).

2.1.3 The dB(A) level is commonly used for the measurement and assessment of environmental noise due to the closer relationship between the perception of loudness, and the and the measured A-weighted sound pressure level of that sound. A change in 3 dB is the approximate difference limen regarding sound level changes under normal everyday listening conditions, whilst a 10 dB increase or decrease in the sound pressure level of a steady sound generally corresponds to a perceived doubling or halving of loudness.

2.1.4 An indication of the range of sound pressure levels commonly found in the unoccupied environment is given below:

Location Lp dB(A) Normal threshold of hearing -10 to 20

Music halls and theatres 20 to 30 Living rooms and offices 30 to 50 Inside motor vehicles 50 to 70 Industrial premises 70 to 100 Burglar alarms at 1 m 100 to 110 Jet aircraft on take-off 110 to 130 Threshold of pain 130 to 140

2.1.5 The LA90,T, or background sound level, is defined by the A-weighted sound pressure level that is exceeded by the residual sound at the assessment location for 90% of a given time interval, T. This does not reflect the occurrence of transient and/or higher sound level events and is generally governed by continuous or semi-continuous sounds. Due to the varying acoustical environment, LA90, T is normally defined separately for day and night-time periods. Other percentiles are also sometimes used to describe the levels of ambient sound exceeded for different periods of time. The LA50,T and LA10,T noise levels denote the level of ambient sound exceeded for 50 and 10% of the time, T, respectively. The LAmax,F sound level denotes the maximum instantaneous sound level in any given period of time obtained using the FAST time weighting.

2.1.6 The equivalent continuous sound pressure level is denoted by the symbol LAeq,T and is defined as the value of the A-weighted sound pressure level of continuous steady sound that, within a specified time interval, has the same mean-squared sound pressure as a sound that varies with time. This average sound level is used in the UK for the measurement of sound from many sources (including industry, construction, railways and aircraft) and is widely used for the measurement of ambient noise, which comprises sound from all sources in the environment.

2072w-SEC-00001-03 3 March 2017

2.1.7 Community responses to environmental sound sources are dependent on both acoustic and non-acoustic factors. The acoustic factors include absolute sound level, changes to, or exceedances of, background and residual sound levels, as well as the characteristic features, time, duration and intermittency of the sound. Noise is defined as unwanted sound.

2.2 National Noise Policy and Planning Policy Framework

Noise Policy Statement for England (NPSE)

2.2.1 The Noise Policy Statement for England (March 2010) [1], sets out the long term vision of Government noise policy.

2.2.2 The vision of the NPSE is to ‘Promote good health and a good quality of life through the effective management and control of noise within the context of Government policy on sustainable development’. This vision is supported by three key aims:

avoid significant adverse impacts on health and quality of life;

mitigate and reduce to a minimum other adverse impacts on health and quality of life; and

where possible, contribute to the improvement of health and quality of life.

2.2.3 The NPSE applies to most forms of noise, including environmental noise, neighbour noise and neighbourhood noise, but not occupational noise in the workplace.

2.2.4 The NPSE has adopted the following concepts to help consider whether noise is likely to have a ‘significant adverse’ or ‘adverse’ impact on health and quality of life:

NOEL – No Observed Effect Level This is the level below which no effect can be detected. In simple terms, below this level, there is no detectable effect on health and quality of life due to noise.

LOAEL – Lowest Observed Adverse Effect Level This is the level above which adverse effects on health and quality of life can be detected.

SOAEL – Significant Observed Adverse Effect Level This is the level above which significant adverse effects on health and quality of life occur.

2.2.5 The NPSE goes on to state that:

“it is not possible to have a single objective noise-based measure that defines SOAEL that is applicable to all sources of noise in all situations. Consequently, the SOAEL is likely to be different for different noise sources, for different receptors and at different times. It is acknowledged that further research is required to increase our understanding of what may constitute a significant adverse impact on health and quality of life from noise. However, not having specific SOAEL values in the NPSE provides the necessary policy flexibility until further evidence and suitable guidance is available.”

2072w-SEC-00001-03 4 March 2017

National Planning Policy Framework 2.2.6 The Government’s National Planning Policy Framework (NPPF) came into force in March

2012 [2] and sets out the Government’s planning policy for England and how it should be applied. The NPPF replaced a number of planning policy guidance documents, including the now archived Planning Policy Guidance 24: Planning and Noise.

2.2.7 The NPPF defines the Government’s planning policy for England and sets out the framework within which local authorities should prepare their local and neighbourhood plans, reflecting the needs and priorities of their communities.

2.2.8 The main references to noise in the NPPF are found in paragraphs 109 and 123, where it states that:

“ 109. The planning system should contribute to and enhance the natural and local environment by:…

preventing both new and existing development from contributing to or being put at unacceptable risk from, or being adversely affected by unacceptable levels of soil, air, water or noise pollution or land instability;…

123. Planning policies and decisions should aim to:

avoid noise from giving rise to significant adverse impacts on health and quality of life as a result of new development;

mitigate and reduce to a minimum other adverse impacts on health and quality of life arising from noise from new development, including through the use of conditions;

recognise that development will often create some noise and existing businesses wanting to develop in continuance of their business should not have unreasonable restrictions put on them because of changes in nearby land uses since they were established; and

identify and protect areas of tranquillity which have remained relatively undisturbed by noise and are prized for their recreational and amenity value for this reason.”

2.2.9 In the preparation of local plans, the NPPF specifies that local planning authorities should:

“set out environmental criteria, in line with the policies in this Framework, against which planning applications will be assessed so as to ensure that permitted operations do not have unacceptable adverse impacts on the natural and historic environment or human health, including from noise, dust, visual intrusion…

when developing noise limits, recognise that some noisy short-term activities, which may otherwise be regarded as unacceptable, are unavoidable to facilitate minerals extraction;”

Planning Practice Guidance - Noise

2.2.10 Planning Practice Guidance (PPG) on noise [3] was issued in March 2014. This web-based guidance advises local planning authorities to take into account the acoustic environment, and in doing so consider the following:

whether or not a significant adverse effect is occurring or likely to occur;

whether or not an adverse effect is occurring or likely to occur; and

Page 8: MacFarlane Lane proposed school site feasibility noise ... · there is no detectable effect on health and quality of life due to noise. LOAEL – Lowest Observed Adverse Effect Level

2072w-SEC-00001-03 5 March 2017

whether or not a good standard of amenity can be achieved.

2.2.11 The PPG includes examples of how to recognise when noise could be a concern and provides example outcomes to which the Observed Effect Levels can apply. The PPG noise exposure hierarchy is presented in Table 2.1, based on the likely average response, along with example outcomes.

2.2.12 While it is acknowledged that planning and nuisance regimes are separate entities, the hierarchy table does provide useful information regarding how the concept of SOAELs and LOAELs, introduced through the NPSE, could be applied and does allow for subjective observations to be considered in the context of potential effect levels. The presence of an “Effect Level” does not infer whether a nuisance is or is not present.

TABLE 2.1: PPG NOISE EXPOSURE HIERARCHY (Source –Planning Practice Guidance)

2.2.13 The PPG guidance states that “if external amenity spaces are an intrinsic part of the overall design, the acoustic environment of those spaces should be considered so that they can be enjoyed as intended.” Furthermore the guidance goes on to so say “Although the existence of a garden or balcony is generally desirable, the intended benefits will be reduced with increasing noise exposure and could be such that significant adverse effects occur.”

2072w-SEC-00001-03 6 March 2017

2.3 Local Authority Noise Criteria

2.3.1 The Hounslow Local Plan [4] details “Policy EQ5- Noise” that requires the location and design of development to have considered the impact of noise, and mitigation of these impacts.

2.3.2 The aims of this policy are to be achieved by LBH by:

a) assessing the potential noise impacts of development proposals;

b) directing noise-sensitive development to locations outside those areas identified where noise exposure is likely to cause adverse effects in terms of public health and well-being and children’s cognitive learning in schools;

c) ensuring noise-sensitive development is protected against existing and proposed sources of noise through careful design, layout and use of materials, adequate insulation of the building envelope (including both internal/external walls and ceilings), as well as protecting external amenity areas;

d) encouraging the uptake of measures to decrease noise nuisance in the built environment; and

e) considering the designation of Quiet Areas and identifying and protecting areas of tranquillity.

2.3.3 Development proposals are required to:

a) carry out noise assessments where there is a change of use to a more noise-sensitive use;

b) minimise noise disturbance from adjoining uses by incorporating sound insulation or alternative forms of barrier;

c) ensure that noise mitigation measures are implemented, to demonstrate compliance with BS8233:2014 [5], as appropriate;

d) demonstrate that the new plant and machinery (including ventilation) do not harm the amenity of neighbouring properties and generate a noise level that us at least 10 dB below the background noise levels; and

e) be located outside the 69 dB LAeq,16hrs noise contour of Heathrow Airport where noise-sensitive uses (including schools) are proposed. This is consistent with Section 2 if the International Civil Aviation Organisation (ICAO) Balanced Approach to Aircraft Noise Management [6] which directs residential developments outside this contour.

2.3.4 The notes that accompany the policy also detail that there will be a presumption against non-residential noise sensitive development in the 63 – 60 dB LAeq,16hrs contour. The notes also detail that between the 57 and 63 dB LAeq,16hr contours all new built development should have the high levels and acoustically treated ventilation.

2.3.5 The London Boroughs of Hillingdon, Hounslow and Richmond upon Thames have published a Supplementary Planning Document: Development Control for Noise Generating and Noise Sensitive Development [7]. This document details that for schools

2072w-SEC-00001-03 7 March 2017

(including free schools) the applicant should refer to “Building Bulletin 93: Acoustic Design of Schools” [8] for further advice.

2.4 World Health Organisation Guidelines for Community Noise

2.4.1 Guideline values for community noise in specific environments are presented in the World Health Organisation (WHO) Guidelines for Community Noise document [9] and the guideline values pertinent to this noise assessment are summarised in Table 2.2.

TABLE 2.2: WHO GUIDELINE NOISE VALUES

2.4.2 The guidelines presented in this WHO document reflect conclusions drawn up after consideration of the most recent international research evidence on the health effects of exposure to noise. The guidelines define the goal of noise management as ‘to maintain low noise exposures such that human health and well-being are protected’, with ‘specific objectives to develop criteria for the maximum safe exposure levels and to promote noise assessment and control as part of environmental health programmes’.

2.4.3 The guideline values presented for outdoor living areas indicate that few people may be moderately or seriously annoyed below the criteria levels of 50 dB LAeq,T and 55 dB LAeq,T respectively.

2.5 Building Bulletin 93

2.5.1 Building Bulletin 93 defines the acoustic standards for new schools and recommendations for existing schools undergoing refurbishment. The guidance states a consensus that low ambient noise levels are required, in particular for Special Educational Needs and Disability (SEND) children having hearing or communication needs including visual impairments, hearing loss or auditory processing difficulty, attention deficit hyper activity disorders (ADHD) and autistic spectrum disorders.

2.5.2 BB93 gives performance standards for indoor ambient noise levels for new build school rooms and refurbishment of spaces. These standards are given as LAeq,30mins, rather than LAeq,16hr, in order to be representative of the period over which a lesson takes place. The upper limits for indoor ambient noise are shown below in Table 2.3.

2.5.3 WHO guidelines and the earlier 2003 revision of BB93 also indicate upper levels for LAeq,during play and LAeq,30mins, respectively, of 55 dB in school playgrounds and BB93 also recommends that at least one area suitable for outdoor teaching activities is below 50 dB LAeq,30mins.

2.6 IOA Guidance: Acoustic Design of Schools

2.6.1 Acoustics of Schools: A Design Guide [10] summarises further design considerations for schools. Within a section providing guidance on the selection of sites for new schools, the document also outlines noise limits for external areas. These limits are as follows:

60 dB LAeq,30min at the boundary of external areas used for formal and informal outdoor teaching and recreation;

55 dB LAeq,30min in any outdoor area used for teaching and recreation; and

50 dB LAeq,30min in at least one area suitable for outdoors teaching.

3. SITE DESCRIPTION AND OPERATION

3.1 Site Description

3.1.1 The proposed site is currently playing and training fields associated with the Grasshoppers Rugby Football Club on MacFarlane Lane, Osterley, London.

3.1.2 The immediate area to the south of the proposed site is taken up by the Sky Media Campus. To the east of site is the Day Group large aggregate depot, with an associated freight railway, which runs approximately 140 m from the north east boundary of the proposed site. From the north to the west of site lies a golf course, with a surface section of the London Underground Piccadilly line also to the north-west, 180 m from the site. Residential properties are located 210 m to the south west, on Oaklands Avenue.

3.1.3 Beyond the immediate surrounding properties, the B454 Syon Lane runs 320 m to the south east, with the M4 motorway 400 m to the north east.

3.1.4 The location of the proposed site in relation to the immediate surrounding area is presented in Figure A1 of Appendix A. A satellite image of the wider area, including surrounding noise sources, is displayed in Figure A2 of Appendix A.

3.1.5 The existing noise climate consists of a combination of air traffic, road traffic and noise associated with the aggregate depot.

3.1.6 The proposed site lies outside of the Heathrow 2014 day actual modal split Leq 57 dB contour detailed in the ERCD report 1501 [11] and this is shown in Figure A3.

2072w-SEC-00001-03 10 March 2017

4. SOUND SURVEYS AND MEASUREMENTS

4.1 Sound Monitoring

4.1.1 Attended short term sound level measurements were conducted to obtain observations of ambient sound levels and dominant sources of sound. The results of the attended measurements are detailed in Table B1 in Appendix B.

4.1.2 Continuous unattended measurements were made at three locations over a 12 day period to measure the variation in sound during the both easterly and westerly operations from Heathrow. The results of the unattended measurements are detailed in Tables B2, B3 and B4 in Appendix B.

4.1.3 The sound level meters were calibrated before and after the measurement surveys using a Rion NC-74 Class 1 Acoustic Calibrator to generate a calibration level of 94 dB at 1 kHz.

4.1.4 All sound level meters used within this survey have been verified as conforming to BS EN 61672-1 [12] within 2 years. Calibration certificates for the equipment used are contained within Appendix C. Field calibration checks were taken before and after the measurements and the calibration drift was 0.0 dB.

4.2 Unattended Sound Survey

4.2.1 Unattended sound monitoring was undertaken between Friday 26th August and Wednesday 7th September 2016 to measure the sound level from easterly and westerly operations from Heathrow. Three monitoring stations were placed in locations representative of the proposed building’s façades. The microphones were each positioned 1.5 m above local ground, and more than 3.5 m away from any vertical reflective surfaces. The unattended measurement locations are labelled as LT1-LT3 on Figure A1 of Appendix A.

4.2.2 The unattended sound measurements were undertaken using 2 no. Rion NL-31 and 1 no. Rion NL-52 precision integrating sound level meters fitted with weatherproof windshields. The sound level meters were powered by gel cell batteries and stored inside weatherproof security boxes.

4.2.3 Consecutive 30-minute measurements of sound indices were obtained, which included LAmax,F, LA01,30min, LA10,30min, LAeq,30min and LA90,30min. Sound levels were measured continuously over the 12 day monitoring period.

4.3 Attended Sound Survey

4.3.1 Attended short-term sound measurements were obtained at various locations around the proposed site.

4.3.2 Short-term attended sound measurements were obtained on Wednesday 7th September between 13:13 hrs and 16:08 hrs to establish existing ambient sound levels. Measurements were taken at three monitoring locations, representative of the proposed school, labelled as ST1, ST2 and ST3 on Figure A1 of Appendix A.

4.3.3 The attended sound measurements undertaken on Wednesday 7th September were made using a Rion NA-28 sound level meter fitted with a windshield and mounted on a tripod to elevate the microphone 1.5 m above local ground. All measurements were undertaken in free-field locations.

2072w-SEC-00001-03 11 March 2017

4.3.4 The sound level meters were configured to measure broadband A-weighted noise levels, dB LAmax,F, LAeq,5min and LA90,5min, in consecutive 5-minute intervals for the attended measurements and 15-minute intervals for the unattended measurements. Both were aggregated into 30-minute indices.

4.4 Measurement Weather Conditions

4.4.1 Weather conditions during the attended monitoring on Wednesday 7th September 2016 were dry and clear. Temperatures were observed as being 29 °C with mean relative humidity values of 45 %. Average wind speeds were measured at 0.3 ms-1, with peak gusts of 2.1 ms-1.

4.4.2 Weather conditions over the unattended monitoring period, from Friday 26th August to Wednesday 7th September 2016 have been reviewed based on site observations and weather data obtained from an online data source (http://www.wunderground.com/). Table B5 of Appendix B presents the measured weather data over the monitoring period.

4.4.3 The weather during the unattended survey period was mostly dry and warm with low winds and only 2 days of more than 1 mm recorded rainfall.

5. MEASUREMENT SURVEY RESULTS

5.1 Unattended Measurement Survey Results

5.1.1 The results of the unattended sound measurement survey are presented graphically in Figures A4, A5 and A6 of Appendix A and summarised in Tables 5.1 to 5.3 below. The full unattended dataset is also presented for reference in Tables, B2, B3 and B4 of Appendix B.

5.1.2 Daytime ambient sound levels between 08 and 15:00 hrs presented in this table have been calculated using logarithmic averaging of 30-minute measurements. The arithmetic mean of the LA10,T, LA50,T and LA90,T sound levels have been presented. The LAmax,F column presents the highest measured LAmax,F during the daytime period. The daytime period has been defined to align with typical core teaching hours of a school.

5.1.3 The results of the unattended sound measurements at LT1 show that during the weekday daytime periods ambient noise levels ranged from 51 to 61 dB LAeq,7hr, with an arithmetic mean of 54 dB LAeq,7hr. The arithmetic mean of the weekday levels ranged from 45 to 49 dB LA90,T.

5.1.4 The results of the unattended sound measurements at LT2 show that during the weekday daytime periods ambient noise levels ranged from 52 to 65 dB LAeq,7hr, with an arithmetic mean of 56 dB LAeq,7hr. The arithmetic mean of the weekday levels ranged from 47 to 52 dB LA90,T.

5.1.5 At LT3, elevated noise levels on two particular days (Tuesday 30th August and Friday 2nd September) appeared to show spurious data with elevated noise levels throughout the day. Discussions with the groundsmen at Grasshoppers rugby club has highlighted that on each of these days, a water sprinkler pump was positioned next to the sound level meter for the duration of the day. As such, noise levels measured on Tuesday 30th August and Friday 2nd September have been removed from the assessment.

5.1.6 The results of the unattended sound measurements at LT3 show that during the weekday daytime periods ambient noise levels ranged from 53 to 65 dB LAeq,7hr, with an arithmetic mean of 59 dB LAeq,7hr. The arithmetic mean of the weekday levels ranged from 47 to 60 dB LA90,T.

5.2.2 Observations made during the attended survey indicate that the ambient sound levels were primarily governed by aircraft taking off from and landing at Heathrow Airport. The attended measurements taken before 15:00 hours are representative of the noise environment when planes are landing/taking off in an easterly direction. After 15:00 hours,

measured levels are representative of when the landing/taking off direction is westwards as the operations from Heathrow switched from easterly to westerly. Other sources of environmental noise included distant road traffic on the surrounding road network and excavator use at the aggregates depot.

5.3 Vibration Measurement

5.3.1 During the noise surveys vibration was not perceptible to the consultants and so no measurements of vibrations were made.

6.1.3 The arithmetic mean of the highest daily LAeq,30min across all monitoring locations (removing any influence from rugby club grounds maintenance), as presented in the above tables is 60 dB, which was measured at LT3.

6.2 Façade Assessment

Natural Ventilation

6.2.1 BS 8233 indicates that an open window will typically provide 15 dB(A) of sound attenuation. Subtracting this figure from the average daily maximum external noise level measured gives a predicted internal noise level of 45 dB LAeq,T. This exceeds the internal noise criteria for standard secondary teaching rooms of 40 dB LAeq,30min by 5 dB. The internal noise criteria for music ensemble rooms is exceeded by 10 dB and the criteria for rooms for pupils with special communication needs is exceeded by 15 dB.

6.3 Outdoor Teaching Noise Limits

6.3.1 Guidance on noise limits for external teaching areas requires noise levels to be below 55 dB LAeq,30mins and for there to be at least one outdoor teaching area with ambient noise levels below 50 dB LAeq,30mins. Based on the measurements obtained at the proposed site, external noise levels are currently 5 dB LAeq,30mins above the criteria for outdoors teaching areas.

6.4 Heathrow Third Runway

6.4.1 Following the Airports Commission recommendation [13] for a third runway at Heathrow the government is expected to announce a decision on whether additional runway capacity will be at Gatwick or Heathrow. If the additional runway capacity is at Heathrow the runway options could change the noise levels at the MacFarlane Lane site.

Page 21: MacFarlane Lane proposed school site feasibility noise ... · there is no detectable effect on health and quality of life due to noise. LOAEL – Lowest Observed Adverse Effect Level

2072w-SEC-00001-03 18 March 2017

6.4.2 If Heathrow is chosen the options are to extend the northern runway or to create a third runway to the northwest. The commission recommended that a package of measures be put in place including respite through runway land flight path alternation, noise insulation and other measures to limit the impact on schools.

6.4.3 If expansion at Heathrow is given approval the location and flight paths will be developed further as part of the scheme development and application for planning consent, through a National Policy Statement, Development Consent Order or Hybrid Bill.

No LAeq,30mins contours were published as part of the Airports Commission consultation. Indicative LAeq,16hr contours were published as part of the noise technical report [14] for the Airports Commission consultation. Figure A7 represents one of these contour plots to give indication that the MacFarlane Lane site is predicted to be between the 57 dB and 60 dB LAeq,16hr contours, though these contours may be subject to revision if and when the flight paths are proposed. The MacFarlane Lane site would be in close proximity to the arrivals path to the third runway, when the airport is on westerly operations.

2072w-SEC-00001-03 19 March 2017

7. MITIGATION

7.1 Internal Noise Levels

7.1.1 In order to reduce internal noise levels to below the recommended limit for students with special educational needs, the building envelope will need to reduce the external noise level by at least 30 dB(A). With windows open, this level of reduction is not expected to be achieved. However, with typical double glazed windows, assuming a reduction of 33 dB(A), internal noise levels are expected to be within the design criteria. Alternative methods of ventilation will be required. These could include:

building wide silenced mechanical ventilation system;

sound attenuating ventilators installed in the window units;

acoustics air bricks installed in the façade; and/or

passive or mechanical silenced ventilation.

7.1.2 The selected ventilation system will need to have a sufficient sound insulation performance so that it does not compromise the internal noise environment inside each type of area in the proposed school.

7.1.3 The LBH PolicyEQ5 requires that development between the 63 and 57 dB LAeq,16hr

contours should have mechanical ventilation. Though this site is outside these contours mechanical ventilation is required to meet the internal noise level criteria.

7.1.4 As the dominant source of noise at the proposed location of the school is aircraft departing from and arriving to London Heathrow Airport, particular attention will need to be paid to the design of the roof construction, ventilation and glazing.

7.1.5 BS 8233: indicates that the above single value Rw values adopted for the estimation of internal noise levels suffice for initial calculations. However, this method can underestimate internal noise levels by up to 5 dB. The Standard therefore requires a more rigorous calculation method, using octave bands, to be undertaken at the detailed design stage to define specific window glazing and ventilation requirements as well as construction details of roofs and external load bearing walls.

7.1.6 Detailed noise calculations are undertaken to guide the design of wall and roof constructions, as well as the selection of window and ventilation units for the proposed school. It is also recommended that acoustic measurements are carried out at an appropriate stage during construction to confirm the sound insulation performance of the buildings. Pre-completion testing by an acoustic consultant is a requirement of BB 93 and the IOA Design Guide.

7.2 External Noise Levels

7.2.1 To reduce external noise levels to below the recommended “Acoustics of Schools: a design guide” good practice limits of 50 dB LAeq,30mins for outdoor teaching areas it may be necessary to provide an area underneath an acoustic canopy or hut, or conduct outdoor teaching at times when the school is not being overflown.

2072w-SEC-00001-03 20 March 2017

8. CONCLUSIONS

8.1.1 An environmental noise assessment has been undertaken at the proposed site of a new “free school” on MacFarlane Lane, Osterley to understand the ambient noise levels at the site and consider the site suitability against acoustic criteria for schools.

8.1.2 The site is outside of the 63 dB Leq,16hr contour where there is a presumption against development and the site also lies outside of the modelled 57 dB Leq,16hr contour.

8.1.3 Unattended sound monitoring was undertaken over school day and extended school day periods to measure the sound pressure levels at representative locations across the proposed site.

8.1.4 Attended sound monitoring was also carried out to understand the spatial and temporal variation in ambient sound levels and to comment on dominant sources in the local area.

8.1.5 Subjective observations indicate that the main sources of sound are aircraft passing overhead, particularly when planes are taking off from Heathrow towards the east. Other noise sources included distant road traffic on the surrounding road network, an aggregates depot and train movements to and from the aggregate depot.

8.1.6 An assessment of the existing ambient noise levels has been undertaken using the criteria provided in BB 93. Internal classroom criteria are expected to be exceeded with windows open to provide natural ventilation and so an alternative form of ventilation would be required. Additionally, external noise levels have been found to be above the “Acoustics of Schools: a design guide” good practice limits for outdoor teaching areas, during the loudest periods of easterly operation. At other times the outdoor teaching areas met the criteria for outdoor teaching areas.

8.1.7 Alternative forms of ventilation to having windows open have been proposed, with detailed calculations to be undertaken at a later design stage, once designs have been produced. A canopy or hut could be used to provide an outdoor teaching space so outdoor elements of the curriculum can be conducted during the worst case easterly operations as well as at other times.

8.1.8 The noise generated by the proposed free school development will also be considered at a later design stage.

8.1.9 A third runway or other operational changes may be consented at Heathrow which could increase the ambient noise levels at the proposed “free school” site on MacFarlane Lane and a higher level of noise mitigation for both internal and external areas may be required.

8.1.10 A noise impact assessment to update the findings of the site feasibility noise assessment will be undertaken for the “masterplan” layout shown in Figure A8.
