1.1 It is proposed to open a new club, under the management of Soho House, as part of a wider redevelopment of an area of Brighton’s seafront. Planning permission for the redevelopment has been granted(application no: BH2015/02443) subject to conditions, one of which relates to plant noise emissions.
1.2 Cole Jarman has previously undertaken a noise survey in order to determine plant noise limits for another part of the scheme. The background noise levels recorded during the survey have now been used to derive separate limits applicable to plant serving each area.
1.3 This report presents the methodology and results of the noise survey defines appropriate criteriain accordance with the requirements stipulated by the relevant planningcondition (no. 8), and detailsa plant noise assessment and mitigation measuresrequired to achieve compliance.
2.1 Soho House is to occupy the eastern half of the wider redevelopment site, units no. 6-8. There will be separate mechanicalservices plant serving a gym and associatedfacilities on one floor, and the club restaurant and bars on the floor above.
2.2 The openinghours of the various areas have yet to be finalised and our assessment has therefore consideredthe full range of hours for which consent may be sought. The designer has informed us that the plant may also run for no more than an hour before and after these hours.
2.3 Based on the above the anticipated worst case operational hours of the proposed plant items are summarised below. We understand that plant serving the westernhalf of the scheme is likely to run during the same hours as the club (non-gym) plant.
· Gym plant: 0500-2300
· Club, including restaurant plant: 0600-0300 hours
2.4 The site is shown within the context of the surrounding area in Figure 1 below. Marine Paradelies to the north and Madeira Drive to the south. The nearest noise sensitive receptorsto the site are hotels and apartmentson the north side of Marine Parade.These are shaded blue.
2.5 Beyond Madeira drive is Brighton Beach and, to the west, Brighton Pier. There are no other noise sensitivelocations to considersouth of the site.

3.1.1 An unattended noise survey was undertaken at one positionfor a period of 48 hours, commencing at approximately 1400 hours on Tuesday 7th June.
3.1.2 Measurements were made at a single free-field position at the north boundaryof the site, approximately 8m from the kerb of Marine Parade. This positionis labelled MP1 on Figure 1 above.
3.1.3 Measurements of the LAeq, LAmaxand LA90 indiceswere recorded over consecutive 15 minuteperiods (see attached Glossary of Acoustic Terms for an explanation of the noise units used).
3.1.4 Noise measurements were made using the equipmentlisted in table T1.

T1 Equipment used during unattended noise survey
3.1.5 The sound level analyser was calibrated before and after the noise survey to ensure a consistent and acceptable level of accuracywas maintained throughout. No significant drift was noted to have occurred.
3.1.6 The weather conditions while setting up and collectingthe survey equipmentwere warm and dry with a gentle breeze; suitablefor the measurements. Based on online weather history data, these conditions are not believed to have varied significantly during the survey.
3.2.1 The results of the noise measurements at MP1 are presented in the attachedtime history figure 16/0368/TH1.
3.2.2 The lowest background noise levels measured during each of the plant operating periods identified in paragraph 2.3 above are shown in table T2.

T2 Minimum measured background noise levels
3.2.3 While on site, the noise climate was dominated by traffic on Madeira Drive.
4.1.1 The site location falls under the jurisdiction of Brighton & Hove City Council. They have granted permission for the redevelopment (application no: BH2015/02443), subject to
conditions. Planning condition 8 relates to noise emissions from new mechanical services plantand reads as follows:
Prior to the installation of plant into the development, an acoustic report shall be submitted for approval to the Local Planning Authority. This must show that the cumulative ‘A’ weighted sound pressure level from the plant and machinery (including non-emergency auxiliary plant and generators), that will be incorporated into the development, when operating at its noisiest,shall not at any time exceed a value of 10 dB below the minimum externalbackground noise, at a point 1 metre outside any window of the nearestresidential or other noise sensitiveproperty, unless and until a fixed maximum noise level is approvedby the City Council. The background level should be expressedin terms of the lowest LA90,15mins duringthe proposed hours of operation. The plant-specific noise level should be expressedas LAeq,T, and shall be representativeof the plant operating at its maximum.
Reason: To safeguard the amenities of the occupiersof neighbouring properties and to comply with policiesSU10 and QD27 of the Brighton & Hove Local Plan.
4.1.2 It should be noted that the requirements stipulated by this condition differ in certain ways from the guidancein BS 4142:2014, which is typically referenced when assessing noise emissionsfrom mechanical servicesplant.
4.1.3 The requirement to restrict plant noise to a level no greater than 10 dB below the minimumbackground level during the operatingperiod goes beyondthe intent of BS 4142:2014. The standard states that “wherethe rating level does not exceed the background sound level, this is an indication of the specific sound source having a low impact”.
4.1.4 Conversely, however, BS4142:2014 requires that plant noise is assessed on the basis of a rating level, which may include penalties for various acoustic features,whereas Planning Condition 8 refers to the combined A-weighted sound pressure level of all plant operatingat a given time. Therefore, in this case there is no need to add corrections for the characterof the plant noise.
4.1.5 Allowance should also be made for plant serving the western area of the redevelopment. Soho House plant intended to run between0600 and 0100 hours should have noise emissions restricted to a level no greaterthan 13 dB below the minimum backgroundlevel for this period. This will permit an equal level of noise to be generatedby plant serving each area.
4.2.1Based on the approachdetailed in the previous section,the noise limitsfor the proposedmechanical services plant are shown in table T3.

Cooling Plant
5.1.1 It is proposedto install five VRF air source heat pumps inside a pair of plant rooms on the northernside of the site.
5.1.2 Two units serving the club (ASHP 1 & 2) will be housed within a plant room at the east end of the lower level, with louvred openingsin the roof and south external wall.
5.1.3 Two more units serving the club (ASHP 3 & 4) and one servingthe gym (ASHP 5) will be located in a plant room near the west end of the upper level with louvred openingsin the roof and north external wall.
Ventilation Plant
5.1.4 The gym will be served by an air handlingunit (AHU 1) and extract fan (EF 1) located in an internal plant room. The AHU intakeand discharge, and extract fan discharge will be ducted vertically out of the building through a louvre covered riser.
5.1.5 A kitchen extract fan (EF 3) is to be installed within the riser, with the exhaust ducted up alongside the AHU 1 and EF 1 atmospheric side ductwork.
5.1.6 An air handling unit (AHU 3) will be installed inside a plant room at the eastern end of the upper floor. The supply air intake for this unit will be ducted to the north external wall and there will be a larger, louvred openingin the roof.
5.1.7 All other plant will be installed fully inside the building, with noise transmitted outside only via ductwork.
5.1.8 A kitchen extract fan (EF 5), two other extract fans (EF 2 & 4) and two heat recovery units (HRU 1 & 2) will connect to grillesin the north side of the building.An air handling unit (AHU 2) will draw air through a grille in the lower floor roof on the same side of the building.
5.1.9 A pair of heat recoveryunits (HRU 3 & 4) and three supply fans will be ducted to grilles on the south side of the building.
5.2.1 An assessment has been conducted on the basis of drawings by CD International Building Services Engineers (CDBSE), dated 5th August 2016, and accompanying schedules of plant equipment. The reference codesused in this report to identify each unit and the locationof any mitigation requirements correspond to those shown on the drawings and schedules by CDBSE. The drawings are attached as Appendix A.
5.2.2 For our assessment we have used manufacturers’ octave band noise data for each plant item, as shown in the attached schedule 16/0368/SCH1.
5.2.3 The assessment has considered two residential receptorsthat will be most exposed to the new plant, north of the site, one near each end. These are labelled AP1 and AP2 on Figure 2 below.
 |
5.2.4 Our assessment has taken into account reverberant sound build-up inside the various plant rooms and riser, sound radiatedfrom louvred openingsand transmitted along ducts to the atmosphere via grilles.
5.2.5 The specific noise levels generatedby the equipment at each location have been calculatedby correcting plant noise levels for distanceand radiation losses, façade reflections and screening where appropriate.
5.2.6 Duct and grille dimensions are not currentlyavailable, due to the outline stage of the design.Conservative estimates, proportional to the size of each plant item, have thereforebeen made in calculating losses for bands, end reflections and grille directivities where appropriate.
5.2.7 A sample of calculations detailing the assessment are attached as Appendix B. A full set of calculation sheets detailing the assessment for each of the plant items can be provided on request.
5.3.1 It will be necessary to implement a range of noise mitigation measures to meet the proposedplant noise limits.These are listed along with their minimum octave band insertion losses in the attached schedule16/0368/SCH2-1.
5.3.2 The ducted units will generallybe the most amenable to noise control, as silencerscan be installed in the air intake and dischargeductwork. Other measures will need to be considered to control noise emissions from the coolingplant and externallymounted fans.
5.3.3 In order to sufficiently reduce noise radiatedfrom the fan casing of kitchen extractfan EF 3, it will be necessaryto house the fan inside an acoustic enclosure. The fan manufacturer, Nuarire, state in their literaturethat they can provide this but it should be ensured that the enclosureachieves the insertionlosses shown in the attachedschedule (ENC 1) while ensuring adequate airflowto the fan and motor and acousticisolation of the unit from the enclosure.
5.3.4 A sound absorbentlining will also need to be appliedto a minimum of 6m2 of the riser in which fan EF 3 is installed. This must be supplied and installed in accordance with the attachedspecification 16/0368/SPC1.
5.3.5 In order to control noise from the air source heat pumps breaking out of the two plant rooms at either end of the site, the louvres to each room should be acoustic louvresachieving the minimuminsertion losses in the attachedschedule (AL1 & 2).
5.3.6 The minimumlouvre insertion losses would typically be achieved by 300mm deep acoustic louvres. Acoustic louvres must be supplied to meet the requirements set out in the attached specification 16/0368/SPC2-1.
5.3.7 Minimum octave band insertion losses for atmospheric side silencers for the ventilation plant, where required, are provided in the attached schedule (AS 1 – 16) along with typical lengths and percentage free areas of silencer that would achievethese values.
5.3.8 The suggested silencer configurations are generally standard rectangular splitter silencers although in the case of kitchen extract fans, understood to be EF 3 and 5, Melinex faced
splitter silencersshould be used. We understand from the manufacturer’s data sheets that fans EF 1, 2 and 4 are likely to have circular ductworkand a cylindrical silencer may be preferable.
5.3.9 All silencers should be suppliedand installed in accordance with the requirements of the attached specification 16/0368/SPC3. Silencer pressuredrops should be limited to no more than 40 Pascals.
5.4.1 With the mitigationmeasures described in the previoussection in place, the assessed plant noise levels are as follows:

T4 Calculated plant noise levels at assessment position
5.4.2 It can be seen that the predictedplant noise levels at the assessment positionssatisfy the plantnoise emissions criteria required by Planning Condition8.
5.4.3 A summary of the total octave band noise levels predicted at each assessmentposition, as well as the relative contributions from each assessedplant item, during each time period are included here as Appendix C.
5.4.4 As explained in paragraph 4.1.5 above, by designingto the limits specified here allowance has also been made for equal levels of noise generated by plant serving the western area of the redevelopment, which will contribute to avoiding excessively onerous restrictions on this plant.
5.4.5 Suitable isolation measureswill need to be incorporated into the detailedplant design to prevent excessivelevels of structure-borne noise from being transmitted to other parts of the building.
6.1 It is proposed to open a new club, under the management of Soho House, as part of a wider redevelopment of an area of Brighton’s seafront.New mechanical servicesplant is proposedto serve the Soho House site and other areas of the redevelopment.
6.2 An unattended noise survey has been undertakenat the site to quantifythe existing noise climate and plant noise emissions limits proposed to meet the requirements stipulated by a planningcondition imposed by Brighton & Hove City Council.
6.3 An assessmentof the noise from the proposed plant items has been undertaken at the nearestnoise sensitive windows.The assessment has shown that the proposedemission limits can be met and a programme of mitigation measuresrecommended to achieve this.
6.4 Headroom has been allowed for noise emissions from further plant equipmentserving the other half of the redevelopment, which is covered by the same planningcondition.

Glossary of AcousticTerms
|
LAeq:
The notional steady sound level (in dB) which over a stated period of time, would have the same A-weighted acousticenergy as the A-weighted fluctuating noise measurement over that period. Values are sometimeswritten using the alternative expression dB(A) Leq.
LAmax:
The maximum A-weighted sound pressure level recorded over the period stated. LAmaxissometimes used in assessingenvironmental noise when occasional loud noises occur, which may have little effect on the LAeq noise level. Unless described otherwise, LAmax is measuredusing the “fast” sound level meter response.
LA10 & LA90:
If non-steadynoise is to be described, it is necessaryto know both its level and degree of fluctuation. The LAn indices are used for this purpose. The term refers to the A-weighted level (in dB) exceeded for n% of the time specified. LA10 is the level exceeded for 10% of the time and as such gives an indication of the upper limit of fluctuating noise. Similarly LA90 gives anindication of the lower levels of fluctuating noise. It is often used to define the backgroundnoise.
LA10 is commonly used to describe trafficnoise. Values of dB LAn are sometimes written using the alternative expression dB(A) Ln.
LAX, LAE or SEL
The singleevent noise exposurelevel which, when maintained for 1 second, contains the same quantity of sound energy as the actual time varying level of one noise event. LAX values forcontributing noise sources can be considered as individual buildingblocks in the construction of a calculated value of LAeq for the total noise. The LAX term can sometimesbe referred to as ExposureLevel (LAE) or Single Event Level (SEL).

Notes
1 - To be read in conjunction with silencer specification
2 - Silencers should be sized such that the stated air velocity(in m/s) is not exceeded.Air velocity is evaluated by dividing the flow rate by
the entire cross-sectional area of the silencer, not just the open or free area. The face veloc ity is calculated so that the pressure drop through the silencer does not exceed 50 Pa.

Acoustic specification of in-duct silencers |
|
Date: |
2 September 2016 |
1 General
1.1 Description
1.1.1 Furnish and install duct silencers of the types and sizes shown on the schedule.
1.1.2 Transitions and support or suspension systems are not included.
1.2 Quality Assurance
1.2.1 The dynamic insertionloss shall meet or exceed the values given in the schedules.
1.2.2 The static pressure drop shall not exceed 40 Pascals.
1.2.3 The levels of airflow noise generatedby the silencers themselves at the operatingconditions shall be provided by the supplier,if requested.
1.2.4 Performance data relating to dynamic insertionloss, static pressuredrop and self-noise shall be obtained in accordance with BS 4718:1971or BS EN ISO 7235 : 1996.
1.3 Submittals
1.3.1 Data sheets on the specific silencersutilised.
1.3.2 An itemisedlist showing the specific silencer utilised, its size, pressuredrop at the required airflow volume, certifiedtest data on dynamic insertionloss and self-noisepower levels.
2 Materials and Construction
2.1 Outer casings and interior construction
2.1.1 Outer casingsof rectangular silencersshall be made of 18 gauge galvanized steel or thickerin accordance with the HVCA recommended construction for high pressure rectangular ductwork. Seams shall be lock formed and mastic sealed.
Specification 16/0368/SPC3
2.1.2 Interior partitions for rectangular silencer splitters shall be made of not less than 26 gauge galvanized perforatedsteel.
2.1.3 Interior construction of tubular silencersshall be compatible with the outside casings.
2.1.4 Splitters in rectangular silencersof length not less than 900mm shall have aerodynamically shaped leading and trailing edges. Square or blunt ends are not acceptable.
2.1.5 Silencers shall be fitted with drilled angle flange connections unless other forms of connection are specified by the MechanicalServices Consultant or Contractor.
2.2 Configuration
2.2.1 Splitters within the silencershould generally be aligned with half width splitters affixed to each side wall of the casing. Splittersshall preferably be aligned vertically, and there shall be a regular splitter/airway dimension across the full width of the silencer. Horizontalsplitters, where this orientation is required, shall be suitablysupported and stiffenedto prevent saggingand restriction of the airways.It is of particular importancethat the supplierensures that parallelsplitter elements are orientated to suit the aerodynamic conditions arising from the adjacent duct geometry, particularly in the vicinity of bends and other transitions.
2.2.2 For silencers manufactured in modules, this specification shall apply to the unit as a whole.
2.2.3 The supplier shall comply with the cross-sectional sizes as shown in the schedule, unless alternative dimensions are agreed and approved by the Mechanical Services Contractor and the AcousticConsultant. Silencers which are constructed to alternative cross-sectional dimensions must achieve the dynamic insertion loss and pressuredrop requirements as set out in the schedule.
2.3 Standard silencers
2.3.1 Filler materialshall be of inorganic mineralor glass fibre of a density sufficientto obtain the specified acoustic performance and be packed under not less than 5% compression to eliminate voids due to vibration and settling. Materialshall be inert; rot, vermin and moistureproof; non-combustible and non-hygroscopic.
2.3.2 The filler material shall be retainedin the splitters in such a manner that there is no egress of the fibres into the air stream at the prevailing flow conditions. Splitterswill normally be faced with perforated galvanisedsheet steel: any other facing material must be approvedby the Acoustic Consultant.
2.4 Silencers with non-porousfibre protection membrane
2.4.1Filler materialshall be of inorganic mineral or glass fibre of a densitysufficient to obtain the specifiedacoustic performance and be packed under not less than 5% compression to eliminate voids due to vibration and settling. Materialshall be inert; rot, vermin and moisture
Specification 16/0368/SPC3
proof; non-combustible and non hygroscopic. Filler material shall be totallyencapsulated and sealedwith Melinex film of a thickness no less than 0.03mm.
2.5 Special silencers with no acousticalfill
2.5.1 No acoustic fill material: glass fibre, mineralwool, foam, etc., are not permitted.
2.5.2 Insertion loss provided by broadly tuned resonators and impedance membranes.
2.6 Special Operating Conditions
2.6.1 Where corrosiveor toxic gases are containedin the air stream, special constructions and materials may be specifiedas an addendum to this specification.
2.6.2 Silencers which are expectedto operate at high temperatures (e.g. turbine exhausts, boiler flues etc.) shall be constructed of a suitablegauge material, with precautions taken to allow for thermal expansion and shock. The filler material inside the splitters shall generally comply with the provisions outlined in Paragraph2.1.C, with modifications as required to accommodate the high operatingtemperature. For very high temperatures, steel wool or equivalent approvedmay be used as the filler material.
3 Execution
3.1 Silencer units shall be delivered to site with blocked ends to prevent the ingress of rubble prior to installation and to reduce the risk of damage.The silencer identification shall be clearly marked on the casing, as shall the directionof airflow.
3.2 The silencersshall be installedin accordance with the manufacturer's recommendations to obtainthe published acoustic and air flow performance.
3.3 The silencers shall be located as shown in the drawings.
3.4 Orientate the internalsilencer splitters as follows for rectangular silencers:
· Silencer splitters be oriented so as to be parallelto the plane of the turn if the silenceris located in a positionless than 3 duct diametersin distance from the elbow. The duct diameter shall be based upon the maximum duct cross sectionaldimension of the silencer.
· If the silenceris located greater than 3 duct diametersaway from an elbow, the orientation is not critical.
3.5 Locate no rectangular or circular silencerswithin one duct diameter from elbows, fan suction or discharge openings takeoffs, etc., unless indicated on the drawings and/or approved by the Acoustic Consultant.
