1.0 Introduction
1.1 Purpose of this Report
This report presents the finding of a noise assessment undertaken for the new building services plant
associated with the proposed extension at Wellesbourne Primary School Annexe, Warwickshire. This version
of the report incorporates revised plant and mitigation details and includes copies of correspondence received
from local Environmental Health Officers (EHO) for reference.
A description of the existing noise environment in and around the site is provided. Noise surveys have been
undertaken and the results used to verify predictions of the short-term and long-term effects of noise. The
noise levels from the proposed development have been predicted at local representative receptors using
CADNA noise modelling software which incorporates ISO 9613 methodologies and calculations.
A list of acoustic terminology and abbreviations used in this report is provided in Appendix A and a set of
location plans and noise contour plots are presented in Appendix B.
1.2 Legislative Context (England)
This report is intended to provide information relevant to the local planning authority and their consultees
in support of a planning application for the above proposed development. Policy guidance with respect to
noise is found in National Planning Policy Framework (NPPF), published on 19th February 2019. With
regard to noise and planning, NPPF contains the following statement at paragraph 170:
“170. Planning policies and decisions should contribute to and enhance the natural and local
environment by:
e) preventing new and existing development from contributing to, being put at unacceptable risk
from, or being adversely affected by, unacceptable levels of soil, air, water or noise pollution or
land instability. Development should, wherever possible, help to improve local environmental
conditions such as air and water quality, taking into account relevant information such as river
basin management plans
A further 2 short statements are presented at paragraph 180, which state:
“180. Planning policies and decisions should also ensure that new development is appropriate for its
location taking into account the likely effects (including cumulative effects) of pollution on health, living
conditions and the natural environment, as well as the potential sensitivity of the site or the wider area
to impacts that could arise from the development. In doing so they should:
Noise Assessment
Warwickshire County Council 2 A112162
Wellesbourne Primary School April 2019
a) “mitigate and reduce to a minimum potential adverse impacts resulting from noise from new
development – and avoid noise giving rise to significant adverse impacts on health and the quality
of life
b) identify and protect tranquil areas which have remained relatively undisturbed by noise and are
prized for their recreational and amenity value for this reason.”
Furthermore, paragraphs 182 and 183 state:
“182. Planning policies and decisions should ensure that new development can be integrated
effectively with existing businesses and community facilities (such as places of worship, pubs,
music venues and sports clubs). Existing businesses and facilities should not have unreasonable
restrictions placed on them as a result of development permitted after they were established.
Where the operation of an existing business or community facility could have a significant adverse
effect on new development (including changes of use) in its vicinity, the applicant (or ‘agent of
change’) should be required to provide suitable mitigation before the development has been
completed.
183. The focus of planning policies and decisions should be on whether proposed development
is an acceptable use of land, rather than the control of processes or emissions (where these are
subject to separate pollution control regimes). Planning decisions should assume that these
regimes will operate effectively. Equally, where a planning decision has been made on a particular
development, the planning issues should not be revisited through the permitting regimes operated
by pollution control authorities.”
Planning Practice Guidance (PPG): Noise provides further guidance with regard to the assessment of noise
within the context of Planning Policy. The overall aim of this guidance is, tying in with the principles of the
NPPF and the Explanatory Note of the Noise Policy Statement for England, is to, 'identify whether the
overall effect of noise exposure is, or would be, above or below the significant observed adverse effect
level and the lowest observed adverse effect level for the given situation.’
A summary of the effects of noise exposure associated with both noise generating developments and noise
sensitive developments is presented within the PPG and repeated as follows:

3.0 Assessment Methodology
3.1 Noise Modelling Methodology
With regard to an assessment of building services plant, three-dimensional noise modelling has been
undertaken based on the monitoring data to predict source noise levels at a large number of locations both
horizontally and vertically. CADNA noise modelling software has been used. This model is based on ISO 9613
noise propagation methodology.
The modelling software calculates noise levels based on the emission parameters and spatial settings that
are entered. Input data, assumptions and model settings as given in the table below have been used.

3.2 Model Input Data
3.2.1 Building Services Plant (BSP) Noise Data
It is understood that one Air Handling Unit (AHU) within an enclosed plant room and two air intake louvres
are to be installed to the southeast of the proposed extension. Two heating, ventilation, and air conditioning
(HVAC) units and two exhaust louvres are to be installed along the northern margin of the proposed
extension. The location of the proposed BSP is shown on SK02 of Appendix B. A vertical area source has
been input into the model to represent AHU breakout from the enclosed plant room and louvre breakout
and two point sources are used to represent the proposed HVAC units; manufacturers’ details of the
proposed plant are presented in Table 3.2 below.

No insertion loss has been applied to the air intake and exhaust louvres, therefore representing a worst-
case scenario.
Table 3.3 below presents the calculated internal reverberant noise level of the AHU room based on worst-
case assumptions, using A-weighted sound power data from the exhaust air (74 dB) of the Swegon Gold F-
20-AD-10000499735.

It has been confirmed that a 300mm deep Sound Block Louvre System (Metador Defender Soundguard –
acoustic louvre doors) is to be installed at the enclosed plant room. This provides a sound reduction of Rw
18 dB. With this attenuation, the output from the AHU plant room with the above reverberant calculations
is 52.2 dB (A).
3.2.2 Building Services Plant (BSP) Operating Conditions
Clarifications from the mechanical engineer regarding the hours of operation and conditions of the plant
have been sought, with the response detailed below:
“General hours of operation for the AHU and AC plant will be as per the normal school hours, allowing for
teaching staff arriving prior to the start of the school day and cleaning staff afterwards – typically 8:00am
to 6:00pm. We would not anticipate HVAC plant to be running for any more than 1 hour each side of these
times to allow for heat-up / cool down.
With regard to frost protection, we have not specified this function, but in any case if such function were
included, running noise levels would be no higher than normal operation.
With regard to defrost mode, this is an automatic function of the specified air-source heat pumps /
condensers. Whilst this function can activate automatically, it would only do so when the units are already
running, within the time range referred to above. Again, running noise levels will be no higher as the units
just goes into reverse mode / cycle.
Finally, regarding the kitchen equipment & extract, this would generally be limited to late morning to
lunchtime.”
As detailed above, the worst-case proposed hours of operation would be between 07:00-19:00 during
weekday periods. Therefore, only daytime hours have been considered within this report.

4.0 Noise Survey
4.1 Noise Survey Methodology
A monitoring survey was undertaken to characterise baseline ambient noise levels currently experienced on
the site and to establish the relative local background and traffic noise levels. Equipment used during the
survey included:
Rion NL-52 Environmental Noise Analyser s/n 253701
Rion NL-52 Environmental Noise Analyser s/n 342867
Rion NC-74 Sound Calibrator s/n 35046823
The measurement equipment was checked against the appropriate calibrator at the beginning and end of
the measurements, in accordance with recommended practice, a drift of 0.1 dB was observed. The accuracy
of the calibrators can be traced to National Physical Laboratory Standards, calibration certificates for which
are available on request.
A baseline monitoring survey was undertaken at five locations (as specified in the following table and shown
in SK01 of Appendix B) from Friday 18th January 2019 to Wednesday 23rd January 2019. Attended short term
measurements were undertaken at three locations during day and evening periods with two additional
locations being measured unattended over a 120-hour period. The raw data collected from the long-term
monitoring is available upon request.
Measurements were taken in general accordance with BS 7445-1:2003 The Description and Measurement of
Environmental Noise: Guide to quantities and procedures. Weather conditions during the survey period were
observed as being dry. Anemometer readings confirmed that wind speeds were less than 5 ms-1 at all times
during the survey, with a predominant westerly wind direction during the survey.

Ambient and background noise levels are usually described using the LAeq index (a form of energy average)
and the LA90 index (i.e. the level exceeded for 90% of the measurement period) respectively. Road traffic
noise is generally described using the LA10 index (i.e. the level exceeded for 10% of the measurement period).
For the long-term (LT) locations, the presented LAeq,T and LA10,T are average noise levels whilst the LA90 is the
modal noise level of each 5 minute measurement over the stated survey period.

5.0 Assessment of Key Effects
5.1 BS 4142 Plant Noise Assessment
This assessment has been undertaken in order to establish the effect of noise from the proposed building
services plant and has been undertaken with the plant operating at full capacity during the daytime period.
The assessment incorporates a 2.0m high acoustic barrier along the southeast corner of the site. The location
of the barrier is illustratively shown on SK02 of Appendix B.
The assessment compares the predicted average noise rating levels from proposed plant with the measured
pre-installation daytime background noise LA90 at the nearest noise sensitive properties. A representative
daytime background LA90 noise level of 36 dB at the closest properties and 40 dB at the closest gardens have
been used. Based on the experience of the assessor of similar plant installations, it is not expected that the
plant would exhibit any tonal characteristics, however, to account for any potential tonal features of the plant
which may be just perceptible at sensitive receptors, an overall +2 dB correction has been applied in line
with section 9.2 of BS 4142:2014.

All values are sound pressure levels in dBA re: 2x 10-5 Pa.
All calculations used to derive the above tables (including averaging of background noise levels and predicted source noise levels) have
been undertaken to 1 decimal place to avoid perpetuation of rounding errors. However, in accordance with BS4142 Para 8.6, the levels
are expressed as integers (with 0.5 dB being rounded up). This may mean that the arithmetic in the above table may appear to be up
to 1 dB incorrect due to this rounding.
The assessment above shows that worst-case plant noise rating levels, with the inclusion of a 2.0m high
acoustic barrier are predicted to be at least 4 dB below background noise levels during the daytime period
at all nearby sensitive receptor locations, which is an indication that an adverse impact is unlikely.

6.0 Conclusions
This report presents the finding of a noise assessment undertaken for the new building services plant
associated with the proposed extension at Wellesbourne Primary School Annexe, Warwickshire. The NPPF
gives test points relating to noise; considering these the following conclusions can be drawn:
• NPPF paragraphs 170 (e) & 180 (a)
Rating noise levels from the new building services plant demonstrate that background noise levels will not
be exceeded at nearby noise sensitive receptors during the daytime with the inclusion of a 2.0m high acoustic
barrier. Therefore, the proposed plant is not expected to have a ‘significant adverse impact’ on health or
quality of life.
• NPPF paragraphs 180 (b), 182 & 183
The proposed building services plant is not expected to exceed background noise levels, nor have a significant
contribution to the ambient noise climate during the daytime. Therefore, it is considered that the proposed
plant would not restrict existing businesses whilst the tranquillity of the area, which is characterised by road
traffic noise, will not be to be affected.

Appendices

Warwickshire County Council A112162
Wellesbourne Primary School April 2019
Appendix A – Acoustic Terminology and Abbreviations
An explanation of the specific acoustic terminology referred to within this report is provided below.
dB Sound levels from any source can be measured in frequency bands in order to provide detailed
information about the spectral content of the noise, i.e. whether it is high-pitched, low-pitched, or
with no distinct tonal character. These measurements are usually undertaken in octave or third
octave frequency bands. If these values are summed logarithmically, a single dB figure is obtained.
This is usually not very helpful as it simply describes the total amount of acoustic energy measured
and does not take any account of the ear’s ability to hear certain frequencies more readily than
others.
dB(A) Instead, the dBA figure is used, as this is found to relate better to the loudness of the sound heard.
The dBA figure is obtained by subtracting an appropriate correction, which represents the variation
in the ear’s ability to hear different frequencies, from the individual octave or third octave band
values, before summing them logarithmically. As a result the single dBA value provides a good
representation of how loud a sound is.
LAeq Since almost all sounds vary or fluctuate with time it is helpful, instead of having an instantaneous
value to describe the noise event, to have an average of the total acoustic energy experienced over
its duration. The LAeq, 07:00 – 23:00 for example, describes the equivalent continuous noise level over
the 12 hour period between 7 am and 11 pm. During this time period the LpA at any particular time
is likely to have been either greater or lower that the LAeq, 07:00 – 23:00.
LAmin The LAmin is the quietest instantaneous noise level. This is usually the quietest 125 milliseconds
measured during any given period of time.
LAmax The LAmax is the loudest instantaneous noise level. This is usually the loudest 125 milliseconds
measured during any given period of time.
Ln Another method of describing, with a single value, a noise level which varies over a given time
period is, instead of considering the average amount of acoustic energy, to consider the length of
time for which a particular noise level is exceeded. If a level of x dBA is exceeded for say. 6 minutes
within one hour, then that level can be described as being exceeded for 10% of the total
measurement period. This is denoted as the LA10, 1 hr = x dB.
The LA10 index is often used in the description of road traffic noise, whilst the LA90, the noise level
exceeded for 90% of the measurement period, is the usual descriptor for underlying background
noise. LA1 and LAmax are common descriptors of construction noise.
Rw The weighted sound reduction index determined using the above measurement procedure, but
weighted in accordance with the procedures set down in BS EN ISO 717-1. Partitioning and building
board manufacturers commonly use this index to describe the inherent sound insulation
performance of their products.

This accessory consists of heaters inserted on the user-side heat exchanger to prevent damage to the hydraulic components due to the formation of ice during periods when the machine is stopped. The power of the anti-freeze heaters is only a few tens of watts depending on the model of unit, namely what is sufficient to prevent breakage of the components. The control monitors (even when the unit is on standby) the heat exchanger outlet probe and when this measures a water temperature below or equal to 5°C (or 2°C below the set point temperature, with differential of 1°C), it switches on the pump (if present) and starts the anti-freeze heater. If the temperature of the outgoing water reaches 4°C (or 3°C below the set point) the anti-freeze alarm will also be triggered; this stops the compressor while keeping the heaters active.
RMMT - Maximum and minimum voltage relay
This device carries out continuous control of the supply voltage of the unit and checks that it is always within an allowable range. If the voltage value stabilizes above or below this range, the device will stop the unit to prevent damage to the electric motors. This device will carry out phase sequence control.
SMAR - Smartlink
This accessory makes it possible to connect the controller of the unit with the controller of a Swegon GOLD™ airhandling unit via a simple serial cable, so allowing their operating logics to be merged into a single consciousness that pursues the maximum energy efficiency of thesystem. The RS485 serial interface is already included and dedicated to connection with Swegon units.
AG - Rubber anti-vibration mounts
These are supplied as a separate package from the unit and must be installed on site following the assembly diagram supplied. They allow you to reduce the vibrations transmitted from the unit to the surface it is standing on.

Noise Assessment
Warwickshire County Council A112162
Wellesbourne Primary School April 2019
Appendix D – Report Conditions
This Report has been prepared using reasonable skill and care for the sole benefit of Warwickshire County
Council (“the Client”) for the proposed uses stated in the report by WYG Environment Planning Transport
Limited (“WYG”). WYG exclude all liability for any other uses and to any other party. The report must not be
relied on or reproduced in whole or in part by any other party without the copyright holder’s permission.
No liability is accepted or warranty given for; unconfirmed data, third party documents and information
supplied to WYG or for the performance, reliability, standing etc of any products, services, organisations or
companies referred to in this report. WYG does not purport to provide specialist legal, tax or accounting
advice.
The report refers, within the limitations stated, to the environment of the site in the context of the
surrounding area at the time of the inspections'. Environmental conditions can vary and no warranty is given
as to the possibility of changes in the environment of the site and surrounding area at differing times. No
investigative method can eliminate the possibility of obtaining partially imprecise, incomplete or not fully
representative information. Any monitoring or survey work undertaken as part of the commission will have
been subject to limitations, including for example timescale, seasonal and weather-related conditions. Actual
environmental conditions are typically more complex and variable than the investigative, predictive and
modelling approaches indicate in practice, and the output of such approaches cannot be relied upon as a
comprehensive or accurate indicator of future conditions. The “shelf life” of the Report will be determined by
a number of factors including; its original purpose, the Client’s instructions, passage of time, advances in
technology and techniques, changes in legislation etc. and therefore may require future re-assessment.
The whole of the report must be read as other sections of the report may contain information which puts
into context the findings in any executive summary.
The performance of environmental protection measures and of buildings and other structures in relation to
acoustics, vibration, noise mitigation and other environmental issues is influenced to a large extent by the
degree to which the relevant environmental considerations are incorporated into the final design and
specifications and the quality of workmanship and compliance with the specifications on site during
construction. WYG accept no liability for issues with performance arising from such factors.

WYG Responses in Blue
SoADC Comment 1
There is not enough information to accurately assess the impacts from this development at this time.
Further information is required in particular - Assumptions made in the propagation model including:
1. Assumptions used for ground hardness and other factors in ISO 9613
2. As submitted plan is not to scale- distances used from sources to receptors
3. Attenuated louvres from AHU- what is the internal plant room noise including reflection. What is the
resulting external noise level taking into account size and construction of louvres
4. The propagation model shows some attenuation provided by fences at the rear gardens of noise sensitive
receptors- what is the construction of this fence and how has it been accounted for in the model
5. What, if any, attenuation has been presumed from the hit and miss fencing surrounding the HVAC units
6. Will there be any noise breakout from the ducting in the roof space
WYG Response 1
1. Hard ground has been used at all locations within the models with ground absorption set to 0,
representing a worst-case scenario.
2. Table 1.0 below documents the distances from the proposed plant to the closest receptors.
Table 1.0 Sensitive Receptor Locations and Distance to Source
Ref. Description Closest Source Approximate Distance To Source (m)
R01 60 Mountford Close AHU 90
R02 62 Mountford Close AHU 70
R03 64 Mountford Close AHU 52
R04 66 Mountford Close AHU 42

R09 76 Mountford Close AHU 66
R10 78 Mountford Close HVAC 98
R11 80 Mountford Close HVAC 112
3. The sound power level of sound break out from the Geniox 14DR AHU is 56 dB(A). The breakout from
the AHU plant room has been included in the model as a vertical area source at 4.1m across and 3.0m high
A112162 February 2019
on the southeast façade of the proposed extension. The vertical area source does not include the effects
of additional louvres associated with the AHU, which would be likely to provide additional noise attenuation,
so transmission loss is assumed to be 0. Therefore, the modelling of the breakout associated with the AHU
is considered to represent a worst-case scenario. All manufacturers’ data associated with the plant is
appended to this document.
4. From on-site observations, the garden fences at the closest receptors are constructed of solid timber,
which have been included in the models as a solid barrier at 1.8m high, which is the standard height for
most garden fences.
5. No attenuation has been included with respect to the hit and miss fencing surrounding the HVAC units,
therefore representing a worst-case scenario.
6. It is understood there will be no noise breakout from ducting in the roof space (which will be located
internally within the building) as the building itself would contain the casing breakout. Furthermore, casing
noise breakout would typically be at least 10 dB lower than from the external termination point and would
have an overall negligible contribution to noise levels when compared to the proposed AHU and HVAC units
to be installed.
SoADC Comment 2
Sound measurements:
7. Justification for measurement locations
8. How does the LAeq and LA90 level change throughout the day- please provide results broken into 1hr periods
(daytime) and 15 Mins (Night time) for the long term measurements. What is the min, max and modal and
average 1hr average (daytime) and 15 mins (night time)
9. What was the weather like during this long term monitoring
10. How do the measurements taken at the LT monitoring sites compare with the attended measurements
WYG Response 2
7. The noise monitoring locations were selected due to their proximity to the closest sensitive receptors
and distances from existing noise sources including the existing school and surrounding road network. The
monitoring locations are therefore considered to suitably represent background level (LA90) in accordance
with the requirements of BS 4142:2014.
8. Tables A1 and A2 within the appendix of this document detail the hourly breakdown of both the long-
term measurements (LT1 and LT2) for the LAeq and LA90 (rounded), including the minimum, maximum and
modal values for daytime and night-time hours during both weekdays and weekends.
A112162 February 2019
Within the BS 4142 assessment, a background level of 36 dB (weekend daytime LA90) for daytime hours
and 28 dB (weekend night-time LA90) for night-time hours were considered to represent typical background
levels when the school was not in use, as shown in the summary table provided in Table 4.3 of the Noise
Technical Report, with data from LT1 used, as it is located next to the closest sensitive receptors. It is
understood that the plant will only operate during weekday hours, however, overall background levels
measured during weekend hours were lower than those measured during the weekday period, and so were
used to represent a worst-case. It is also understood that the plant is unlikely to be operational during
night-time hours, however this was assessed to demonstrate that if the plant were to be operational during
the night-time, noise levels would still fall below existing background noise levels at all sensitive receptors.
Although monitoring location LT2 lies closer to sensitive receptors R08-R11, if baseline data from this
location were to be used (daytime LA90 levels of 40 dB and night-time LA90 levels of 18 dB) noise rating
levels from the plant would still fall at or below background levels during the daytime and night-time
periods.
9. Weather data from Wellesbourne Airfield was reviewed, which identifies that conditions during the long-
term monitoring were observed as being mainly dry, with average temperatures between 2o and 4O Celsius
with wind speeds of up to 7kts (3.6 m/s). Further meteorological conditions observed during the short-
term monitoring period are detailed in Table 4.2 of the Noise Technical Report.
10. Short-term measurements were undertaken during the daytime period (07:00-23:00). The results are
summarised in Table 4.3 of the Noise Technical Report. The LAeq and LA90 levels from at the long-term
monitoring locations and the short-term monitoring locations match closely as shown below in Table 2.0.
Table 2.0 Comparison of Long-term and Short-term Monitoring
Monitoring LAeq (dB) LA90 (dB)
Long-term 49.9-61.7 36.0-42.0
Short-term 44.9-64.9 36.5-44.8
SoADC Comment 3
Background sound levels:
11. How were the representative background sound levels at the noise sensitive properties derived for the
BS4142 assessment how does this compare to the worst case 1hr (daytime) or 15 min (night-time) period
WYG Response 3
11. Considered in Response 2 (8).
A112162 February 2019
SoADC Comment 4
Sound sources:
12. More information is required into the hours of operation of the various pieces of equipment including their
hours of operation
13. The assessment has assumed a 2dB penalty for tonality Is a penalty for intermittency also appropriate
given hours and times of operation
14. If it is the authors experience that tonal noise is not attributable to this type of equipment but that it is
likely to be otherwise distinguishable against the residual acoustic environment a penalty of 3db should be
applied
15. Do the HVAC have defrost mode and what sound level is this. Is this an automatic function that can occur
at night
16. The extract louvre from the kitchen extraction doesn’t seem to be assessed- this is apparently located at a
high level to the North East of the proposal. What is the impact of this noise on the assessment
WYG Response 4
12, 15 & 16. The assessment has been undertaken assuming all items of plant are working at full capacity,
simultaneously during daytime and night-time hours, to present a robust assessment, even though it is not
anticipated to occur. Clarification from the mechanical engineer regarding points 12, 15 and 16 have been
sought, with the response detailed below:
“General hours of operation for the AHU and AC plant will be as per the normal school hours, allowing for
teaching staff arriving prior to the start of the school day and cleaning staff afterwards – typically 8:00am
to 6:00pm. We would not anticipate HVAC plant to be running for any more than 1 hour each side of these
times to allow for heat-up / cool down.
With regard to frost protection, we have not specified this function, but in any case if such function were
included, running noise levels would be no higher than normal operation.
With regard to defrost mode, this is an automatic function of the specified air-source heat pumps /
condensers. Whilst this function can activate automatically, it would only do so when the units are already
running, within the time range referred to above. Again, running noise levels will be no higher as the units
just goes into reverse mode / cycle.
Finally, regarding the kitchen equipment & extract, this would generally be limited to late morning to
lunchtime.”
As detailed above, the worst-case proposed hours of operation would be between 07:00-19:00 during
weekday periods. During these hours, noise levels are predicted to be up to 10dB below background levels
and would therefore have no impact on the closest sensitive receptors
The kitchen extract louvre is located on the northern façade of the proposed extension, which faces away
from the closest sensitive receptors. Also, as detailed above, the extract louvre would only be used during
A112162 February 2019
late morning to lunchtime hours. As the noise levels from the AHU and HVAC fall at least 10 dB below
background levels during the daytime, it is unlikely that noise from the kitchen extract louvre will have an
adverse impact on sensitive receptors.
13 & 14. The proposed plant is not expected to have any tonal features that would be readily distinguishable
against the existing background, however as a worst-case assumption, a 2 dB penalty for any potential
tonal elements that may be just perceptible was applied. No further corrections were added as predicted
noise levels during the daytime are 10 dB below the background noise level which would be imperceptible
and indistinguishable when, for instance switching on.
SoADC Comment 5
What is the impact of uncertainty in the assessment including uncertainty in propagation, source sound
levels, and deriving background measurements.
WYG Response 5
Guidance presented in BS 4142:2014 details steps necessary to reduce uncertainty within assessments.
The points below detail the steps taken to reduce uncertainty within the assessment:
• Noise source data from the AHU and HVAC units has been taken from published manufacturer’s data
(appended to this document). The sound power levels have been used within the model, with no
attenuation provided from the louvre associated with the AHU and hit and miss fencing around the HVAC
units, therefore representing a worst-case scenario.
• The locations selected for the noise monitoring survey were chosen as they represent the closest sensitive
receptors in terms of proximity to the proposed plant reducing the uncertainty level of the residual noise
environment prior to installation of the plant.
• The long-term monitoring was also carried out over weekday and weekend periods, even though the likely
operational hours of the plant is weekday only.
• Hard ground has been used in the models as this provides no attenuation between the proposed plant and
closest receptors therefore the noise propagation characteristics are considered to be representative of a
worst-case scenario.
• As detailed in response 2 (8), worst-case background levels were chosen from the LT1 weekend period to
determine background noise levels in the absence of contributions from the existing school, even though
the plant is likely to only be operational during the weekday period. A night-time assessment was also
undertaken even though the plant is only to be operational during the daytime. The assessment therefore
represents a worst-case scenario.
• All monitoring equipment was appropriately calibrated as detailed in Section 4.0 of the Noise Technical
Report.

Alarms are logged in an alarm list. The list shows the type of alarm, date and time for the alarm and alarm class:• Class A alarm• Needs to be acknowledged• Class B alarm• Needs to be acknowledged• Class C alarm• Returns when the cause of the alarm disappear
Flexible System
A qualified service technician - on the site and at the request of the user - will be able to adapt the regulation further to the requirements of the users;• The air flow regulation can be changed between several methods that are constant air volume through
the fans, constant pressure in the ducts, CO2 dependant control or humidity dependant control. Temperature controlled airflow, which either decrease or increase airflow to achieve heating or cooling demand.
• The temperature control mode can be changed between room temperature control, supply air temperature control, extract temperature control and outdoor compensation of the selected temperature. Summer/winter dependent switching between extract air/room temperature control and supply air temperature control.
• In addition to the fixed schedule, an external start signal for extended operation is available, 3 levels• In addition or as an alternative to the fixed schedule, an external stop input signal is available.• A large number of other alternative functions are also optional.
Recovery with rotary heat exchanger
The capacity of the rotary heat exchanger is steplessly controlled via the modulated control of rotor speed.
Extended running - normal, reduced speed, high speed and stop
Extended running can be activated in 3 ways:• Digital input for normal, reduced, high, stop.• From the start page of the NaviPad at normal speed.• Signal from BMS system for normal, reduced, high, stop.

Communication to BMS systems via BACnet, IP
The controller has been prepared for BACnet via TCP/IP (LAN).This can be used for communication with a BMS system (Building Management System).
Supply air temperature control
• The control of the supply air temperature is based on the value from the sensor mounted in the supply air duct.
The supply air temperature is controlled by a PID-controller (PID control loop). The set-point for the supply temperature can be adjusted from the control panel.
Air flow control - m3/h, l/s, m3/s, CFM
The air flow rates of supply and extract air are controlled separately. The supply and extract air at low, normal, high airflow are set separately on the control panel.On each fan a pressure transmitter measures the difference between the pressure before the fan and the pressure at the measuring probe in the inlet cone. Through a formula with a factor for each fan size, the output signal from the pressure transmitter is used to calculate the actual airflow.A PID-controller maintains the set point value by controlling the speed of the fans.
Supply fan with EC motor
The supply air fan is driven by an EC motor with the impeller mounted directly on the motort. All parameters in the motor speed control have been configured and tested from factory.
Extract fan with EC motor
The extract air fan is driven by an EC motor with the impeller mounted directly on the motor. All parameters in the motor speed control have been configured and tested from factory.
GXU-HP compressor system with cooling recovery, cooling and heating function
The complete compressor system is in a separate section with rotary heat exchanger, coils and the system for the control of safety functions as well as the capacity. The system is able to provide cooling or heating of the supply air.The main controller in the cabinet for the air handling unit delivers a start/stop signal and 0-10V DC signal for control of the capacity between 5 % and 100 %. The separate controller in this section converts the signal to the capacity required.To promote maximum reliability, the system has an automatic capacity reduction system for reduction of the risk of cut off due to overheating. The system is provided with refrigerant and tested for easy start up on the site.The power supply for the compressor system is delivered from the main cabinet for the air handling unit.The main controller in the cabinet for the air handling unit is able to control the cooling recovery by the rotary heat exchanger with the advantage that the outdoor air is precooled by the rotary heat exchanger,

SoADC Comments
1. Gardens: In relation to distances to receptors- BS4142 clearly indicates that garden areas can be used
for assessment. I think this is reasonable as noise is likely to be daytime only and residents should have
their garden areas protected from significant noise. The assessment locations should therefore include the
closest point of the garden areas of the effected properties for daytime (no’s 68 and 70). The rating at this
point should have suitable penalties applied if they are perceptible.
2. Barriers: The model also assumes a solid barrier at the end of the gardens of the neighbouring properties.
The effectiveness of a barrier depends a on its size, density and construction. One of the neighbouring
gardens does not have a fence at all -just a hedge. In any case to consider that garden fences should be
modelled as solid, especially as they are outside the control of the application, is not appropriate. Therefore
the fence should be excluded from the model if it is relied upon to make the noise an acceptable level
(bearing in mind the assessment location in the gardens above). The AHU plant room louvres are also 3m
high whereas the fence is 1.8m. If barriers are necessary they should form part of this application and
suitably specified in the report. They should be designed to be higher than the noise source by at least
0.5m- this may involve lowering the height of the louvres. Full calculations should be provided.
3. Noise source: It is not clear whether the 56dB quoted from the Geniox 14DR AHU is a sound power and
this is not clear in the manufacturers documentation. Actual sound pressure levels incident on the louvers
from the plant room will consist of both direct and reverberant sound. Calculations for the sound pressure
level incident on the louvres should be provided. Details of and construction of the acoustic louvres of the
plant room (including manufacturers stated insertion loss) and then the resultant external sound pressure
level should also be provided.
WYG Response
With respect to the comments above, an additional assessment which considers worst-case garden
receptors has been undertaken at the closest point at house numbers 68 and 70 on Mountford Close (shown
on SK01). The assessment has been carried out with no barriers to garden areas. Table 1.0 below presents
the calculated internal reverberant noise level of the AHU room based on worst-case assumptions, using
A-weighted sound power data from the exhaust air (79 dB) of the Geniox 14DR.

Details of the acoustic louvre doors (Metador Defender Soundguard) for the AHU plant room are appended
to this document. It has been confirmed that the 300mm deep Sound Block Louvre System single figure
sound reduction of Rw 18 dB is to be used. As shown within the manufacturers specification attached,
spectrum data is not available. However, with this attenuation, the output from the AHU with the above
reverberant calculations is 56 dB (A), the same as the breakout sound power level detailed within the
manufacturer’s data for the Geniox 14DR.
The assessment of noise levels within the closest point of gardens 68 and 70 on Mountford Close is shown
in the table below. The BS4142:2014 assessment is inclusive of a +2 dB correction in accordance with the
previous assessment.

A background noise level has been taken from the LA90 measured during the weekday daytime period at
LT1, which lies on the boundary of gardens 68 and 70 (as shown in SK01 of the Noise Technical Report)
and is therefore considered to be the most representative existing background noise level of this location.
Figure 1.0 below shows statistical analysis of the weekday daytime period at LT1. For this distribution of
data, in accordance with the guidance presented within BS4142:2014, the modal LA90 of 42 dB has been
used within the above assessment.
Figure 1.0 Statistical Analysis of LT1 Weekday Daytime Period
The results in Table 2.0 show that worst-case noise levels from the proposed plant are predicted to be no
more than 3 dB above background noise levels within the corner of the closest gardens, under worst-case
assumptions, in the absence of any screening. This change still falls within the Lowest Observed Adverse
Effect Level and is an indication that an adverse impact is unlikely.

The Defender Soundguard is designed to reduce sound transmittance for many external and internal applications. It is available in almost any size and is manufactured to suit the customer requirements. It has been designed to block sound up to Rw52dB.
Over panels / Side panelsAvailable to suit customer requirements.
Door Leaf
Manufactured from two 1.5mm Galvanised steel skins, folded and mechanically fixed to form a strong and rigid 45mm thick door leaf, filled with a variety of acoustic cores. Anti-jemmy flanges to the leading edge of the leaf provide excellent jemmy resistance.
Frame
90mm frames are pressed from 2mm Galvanised* steel to form a single rebated profile. Profiled headers form a smooth butt joint with the vertical posts and are joined together utilising strong M8 bolts to provide positive rigidity. The special fast fit frame is able to compensate for most irregularities in the opening with 8no threaded fixing adjusters per doorset. They permit a tolerance of up to 18mm on each side of the door. Shims and packers are not necessary making an extremely secure fix. Frames can be insulated if required.
Thresholds
DDA compliant 2mm stainless steel threshold bolted into the vertical frame posts. Available in outward opening, inward opening and ramped. An auto drop-seal is added for sound reduction for certain sound levels.
Seal
A variety of different acoustic perimeter seal systems available to meet your sound reduction requirements.
Hardware
Door leaves are hung from 4no stainless steel hinges for smooth operation and optimum weather resistance. Security dog bolts secure the leaf into the frame if the hinges are attacked. Additional hardware includes a range of locks, latches, lever handles, panic hardware, closers and stays. On double doors, lever-action flush bolts can be installed within the leading edge of the inactive door leaf.
Finish
Available in any RAL or BS standard or marine-grade powder-coat finishes.
Vision Panels
A full range of vision panels with acoustic glass with varying sound reduction levels.
Acoustic Door Louvres
Sound Block Louvre System
An acoustic louvre is somewhat of a contradiction in terms; a louvre is designed to allow the passage of air through a door, but at the same time it will permit the passage of sound. The SBLS is designed to reduce the amount of sound passing through the door whilst still allowing air to flow. In acoustic tests, our 300mm deep SBLS louvre has achieved a sound reduction of Rw18dB, and the 600mm deep SBLS louvre Rw32dB. Louvre panels to any sizes are available. Both solid, louvred and glazed over panels and side panels can be manufactured to suit individual customer requirements.*
