1 Plant Areas External plant must meet the following noise suppression requirement as adopted by the Landlord: 1. Air handling units 45db measured at 3metres from source. 2. Heat rejection plant 45db measured at 3metres from source. 3. Supply and exhaust fans 45db measured at 3metres from source.

Yellow m above the roof of any neighbouring retail/leisure area. n/a Table 2: Plant Noise Emission Limits The daytime period is hrs and the night time period is hrs. A nominal reference time period, T, of 5 minutes applies for plant noise, as this is consistent with the night-time reference time period used in BS The boundary noise limits are free-field levels, derived from consideration of the prevailing free-field background noise on site during the night period, with an allowance of 5 db for the summation of a number of tenancies plant operating simultaneously. An increase of approximately 3 db can be expected, and is acceptable, for positions 1m in front of an elevation. Emergency equipment should not be tested at night.

2 Noise Emission Limits Generally These limits apply to noise from the internal activities only (e.g. amplified music). Plant noise limits are specified separately. Colour on plan Limit db Location App. A Residential site boundary and piazza. Green 25 Non-residential site boundary. Red 33 Public external areas and within 1m of any other retail/leisure façade. Blue 35 External services areas and roads. Yellow 40 1m from façade of the leased area which is emitting the noise. N/A 50 Table 1: Entertainment Activity Noise Emission Limited The noise limits are free-field levels, derived from consideration of the prevailing free-field background noise on site during the night period, with an allowance of 3 db for the summation of a number of tenancies operating simultaneously. An increase of approximately 3 db can be expected, and is acceptable, for positions 1 m in front of an elevation (except in the case of measurements made 1 m from the façade of the unit emitting noise where a higher noise level is acceptable, as set out in Table 1). A nominal reference time period, T, of 15 minutes applies for amplified music. (Note: the Environmental Health Officer might adopt a reference time period of 5 minutes if carrying out a survey at night according to BS 4142). The music level has to be contained as such, so the level does not spread out of the unit. Speakers need to be kept inside the unit, not too close to the door.

Any internal lining. In addition to Category B construct to Category C tenant s side of the party wall an Internal independent wall lining, comprising two layers of 15mm wallboard (or 2 x 12mm Soundblock) on independent studwork to create a cavity of not less than 100mm between the internal face of the plasterboard and the face of the blockwork wall. 50mm mineral fibre (density at least 30 kg/m³ in the cavity). No upgrade from Cat. B required for service corridor walls or structure spanning more than the leased area, except where the noise source is immediately adjacent the landlord construction i.e. flanking transmissions. In addition to Category C, construct to the Category D Tenant s side of the party wall; a further internal independent wall lining comprising two layers of 15mm wall board (or 2 x 12mm Soundblock) on independent studwork to create a cavity of not less than 200mm between the internal face of the plasterboard and the external face of the Category C plasterboard. 50mm mineral fibre (density of at least 30 kg/m³) in the cavity.
