Planning Supporting Statement

Central Library, Abington Street, Northampton, NN1 2BA

Proposed electrical upgrade works to the basement, ground and first floors

1.0 Introduction

1.1 The Applicant

This Application has been prepared by Lambert Smith Hampton (LSH) on behalf of Northamptonshire

County Council, in support of an application for proposed electrical upgrade works at Central Library,

Abington Street, Northampton

1.2 Proposal

The proposed works include electrical upgrades to enhance the current electrical distribution

installation, improve lighting whilst reducing energy consumption, improving the escape safety

systems, and improve assistance for Library users with impaired hearing.

1.3 Purpose of this statement

Local Planning Authorities require the submission of a Planning Supporting Statement (PPS) to

accompany Design and Access Statements (DAS), which are intended to assist the deliverance of

quality and inclusive design. The PSS should summarise the land use planning background, history

and policy context for the scheme.

1.4 Pre application Discussions

Due to the Grade 2 listed status of the building, considerable thought has been given to the method of

installation of the replacement lighting and fire alarm systems. With a view to minimising the

disruption caused to the internal fabric of the building, a site meeting was held with the Conservation

Officer from Northampton Borough Council prior to the application being made

2.0 Site and Surroundings

2.1 The Site Use

Central Library is Northamptonshire’s largest public library with over a thousand visitors per day

providing books, audio books, CD’s and DVD’s for loan. Central Library specialises in drama,

information and local history.

2.2 Architectural and Historical Significance

Central Library is a Grade 2 Listed Building set over three floors. Externally the building features a

classical rusticated stone facade incorporating typical features such as a decorative stone balustrade

set above a stone cornice, decorative dental course and frieze. Further embellishments include a

series of pediments and keystones above window openings and above the decorative stone statues

affixed to the front elevation. Internally, the building features typical decorative finishes such as

decorative cornices and archways, with the main feature being a marble staircase from first floor level

down to basement level.

2.3 The Site Setting

Central Library is situated on Abington Street; the main shopping street in the heart of Northampton

Town Centre. Within this setting, there are buildings of various age and construction, resulting in an

eclectic display of architectural styles. It is our opinion that the historical and architectural merits of

Central Library are best enjoyed when viewing the front façade.

2.4 Site Planning History

There have been three previous applications in relation to the site within the past 5 years. Table 2.1

presents the details of the previous applications.

3.0 The Scheme

3.1 Scheme Description

The main drivers for the proposed alterations are:

• Enhance the electrical distribution installation circuit protection and isolation

• Improve lighting and reduce the energy consumption

• Improve the escape safety systems

• Assist library users with impaired hearing

The upgrade works to the electrical distribution boards will see the replacement of obsolete

distribution boards and redundant equipment, together with the replacement of a number of non-

compliant circuits. The works to the current lighting set-up will see the replacement of obsolete and

inefficient luminaries with energy efficient fittings, alongside upgrading the emergency lighting

installations to meet current standards. The existing obsolete and non-compliant fire alarm system will

also be replaced to meet current standards. These works also include for the installation of a hearing

assistance system to the reception and help desks to further enhance the use of the building by

assisting Library users with impaired hearing.

The proposal is to undertake the above specified works to the existing electrical services installations

to address a number of health and safety issues and to improve the energy efficiency of the property,

together with enhancing the library for the users.

3.2 Scope

The alterations will involve works taking place on the first, ground and basement floors. We do not

consider the works to be invasive and do not expect the architectural and historical importance of the

building to be compromised in any way.

3.2 Considerations

The works have been carefully designed to protect the historical fabric of the property by following

existing conduit and cable routes where possible and specifying new materials which are in keeping

or complement the existing features of the property, whilst at the same time complying with current

regulations.

We consider that the true value of the building is in the main front façade of the building overlooking

Abington Street. The proposed works are internal only and will further enhance the Library for all

users, whilst improving energy efficiency and prolonging the future use of the building. We consider

these changes as necessary, if the heritage assets of the Library are to be maintained in the long

term.

4.0 Planning Policy Context

4.1 National Planning Policy Framework

In March 2012 The Department for Communities and Local Government published the National

Planning Policy Framework (NPPF). The NPPF is intended to achieve sustainable development.

Section 12 of the NPPF is specifically concerned with the conservation and enhancement of the

historic environment, which includes buildings, landscape, towns and villages. The NPPF seeks to

enhance heritage assets to ensure their continued use and enjoyment for future generations.

The works as proposed throughout this planning supporting statement are intended to enhance the Library for all users in a number of ways. Firstly, improved lighting will not only better meet the lighting requirements within the library improving comfort for the users, but will also see greater efficiency, prolonging the long term use of the building. Secondly, the emergency lighting and replacement fire alarm system will ensure that Library users are able to exit the building safely should an emergency situation arise, and thirdly, the provision of hearing assistance to the reception and help desks will see further enhancements for users with impaired hearing. We consider that the proposed works will enhance and improve the usability of the Library, and will effectively prolong the life and use of the building, maintaining it as a heritage asset to be used and enjoyed by future generations. Through consulting the NPPF, it is our opinion that the proposals would not materially harm the value of the building, as the proposed works are, in the main, an upgrade to the existing lighting and fire alarm arrangements within the Library, and no structural alterations or significant material alterations.

1.1 USE

1.1.1 General The Central Library is Northamptonshire’s largest public library with over a thousand visitors per day providing books, audio books, CD’s and DVD’s for loan. This Library specialises in drama, information and local history. The library is accessed by the public off Abington Street. The main staff entrance is at the rear of the property where there are approximately 5 No. staff car parking spaces. The property is Grade II listed. The rear of the site also accommodates a REC electrical sub-station, from which the premises are served.

1.2 SCOPE OF PROPOSED WORKS

1.2.1 General The proposal is to undertake the following works to the existing electrical services installations to address a number of health and safety issues and to improve the energy efficiency of the property:- a. Upgrade works to the electrical distribution system. This work will involve the replacement

of obsolete distribution boards and redundant equipment, and the replacement of a number of old and non-compliant circuits. These works will address the Observation and Recommendations as recorded in the current BS7671 Electrical installation Periodic Inspection Report for the premises.

b. Replacement primary lighting - the replacement of obsolete and inefficient luminaires to

areas as identified upon FKH drawings 3797/E-04B, E-05B & E-06B. c. Upgrade of Emergency lighting installation - the upgrade of the emergency lighting

systems to meet BS EN 5266 and BS EN 5499. d. Replacement Fire alarm system - the replacement of the existing obsolete and non-

compliant fire alarm system with a fully addressable BS 5839 system as identified upon FKH drawings 3797/E-07B, E-08B & E-09B.

e. Provision of Hearing Assistance system to the reception and help desks. The proposed works will enhance the electrical distribution installation circuit protection and isolation, improve lighting and reduce the energy consumption, improve the escape safety systems, and from a DDA perspective assist Library users with impaired hearing. The works have been carefully designed to protect the historical fabric of the property by following existing conduit and cable routes where possible and specifying new materials which are in keeping or complement the existing features of the property, whilst at the same time complying with current regulations.


1.3 ELECTRICAL SERVICES LAYOUT

1.3.1 General Details of the proposed primary and emergency lighting and fire alarm system are detailed in the preliminary electrical services layout drawings 3797/E-04B to 09B as contained within Section 1.8.1 Drawings. The major builders works and redecorations associated with the electrical upgrade works are detailed upon LSH drawings 0044663/011, 012, & 013.

1.4 PROPOSED EQUIPMENT, LUMINAIRES & ACCESSORIES

1.4.1 Electrical distribution These works will involve the replacement of all obsolete and non-compliant electrical distribution equipment, some of which is located in public areas. New distribution equipment to public areas will be enclosed within emulsion painted timber lockable enclosures (to match some of the existing) or otherwise be provided with lockable doors as indicated upon FKH drawings 3797/E-04B, E-05B & E-06B. The existing cable containment will be used to avoid damage to the building fabric and minimise the need to install additional surface cabling systems. Where surface cabling is necessary to public areas this will be contained within white PVC mini-trunking as per the existing installations. Proposed major runs of PVC trunking is indicated upon FKH drawings 3797/E-07B, E-08B & E-09B. New timber framed plywood clad containment to conceal new and existing cabling to be provided to underside of the ceiling to the main stairs between ground and basement levels as detailed upon LSH drawings.

1.4.2 Primary and emergency lighting These works will involve the replacement of the existing primary lighting all areas of the premises with the exception of:-

• Grd floor Entrance – 02 which incorporates acceptable luminaires and is to undergo some lamp replacement only.

• Basement Discovery area – 40 & 41 which has been recently refurbished. • 1st floor Carnegie Hall and associated rooms – 23, 24, 61 & 62 which is being

considered as a separate future project. The emergency lighting installation is being upgraded throughout the premises to comply with current BS and H&S requirements. It is proposed that the luminaires to the open library areas will be of the suspended direct/indirect light distribution type incorporating dimming ballasts with daylight compensation controls. This proposal will provide for a more energy efficient scheme, increased ceiling luminance, and easier maintenance. Details of these luminaires are contained in Section 1.9.2. – Luminaire Schedule/Information. The 9nr Type N1 luminaires to the first floor Library Area – 30 will be replaced by 320W Metal Halide luminaires of similar appearance and suspension type/height as the existing fittings. These will incorporate dimming ballasts and be controlled via a daylight compensation detector to improve the energy efficiency.


The existing cable containment systems and luminaire positions are being retained generally throughout to thus avoid any necessary major cable infrastructure and redecoration works. The primary lighting controls will generally be as follows:- a. Open library areas to ground and first floor – wireless luminaire controls to minimise any

necessary additional surface installations required to provide controls at a more convenient location for staff. Where manual switching /controls are necessary these will be in keeping with the existing installations.

b. Staff areas/rooms, staircases, and lift lobbies – local presence detectors, wired to

presence or absence as appropriate. The emergency lighting installation will consist of LED technology fittings, and will incorporate local keyswitches to facilitate testing. Details of these luminaries are contained in Section 1.9.2 - Luminaire Schedule/Information.

1.4.3 Fire alarm system The proposed system will incorporate of both wired (cabled) and wireless equipment throughout the building. The system concept is to wire/cable a discretely installed addressable loop back-bone upon which wireless translators will be connected that will support the proposed wireless detection to open library areas, and thus avoid any surface wiring over decorative/ornate cornices and to ceilings. The wired addressable loop will emanate from the main control panel located at the library entrance and will be installed surface to the following areas and as detailed on FKH drawings 3797/E-07B, E-08B & E-09B.

• Main staircase, shop and recording areas (enclosed in white surface mini trunking similar to the existing installations.

• Side staff staircase serving the electrical switchroom and escape from the Carnegie room.

• Basement library area utilising the suspended ceiling void where possible. • Basement admin areas (book storage, offices and plantroom.) • Rear staircase and staff amenity and office areas to ground, mezzanine and 1st floors.

Any necessary cabling to open library/public areas will be contained in white PVC mini-trunking, installed in a manner to minimise visual impact (similar to the existing installations.) The system will incorporate a repeater panel which will be located with the ground floor fireman’s lift lobby.

1.4.4 Hearing assistance systems These will be of the under-counter induction loop type, installed to the existing furniture in a discrete manner. These will be powered from existing local 13A socket outlets.

1.5 LANDSCAPING

1.5.1 General All the proposed works are of an internal services nature only and therefore no changes to the external appearance of landscaping of the building.


1.6 APPEARANCE

1.6.1 General The proposed works will not change the external appearance of the building. The proposed works are for the upgrade of the internal electrical services only. The main internal appearance changes will be associated with the new light fittings as detailed at the rear of this document. These electrical works will necessitate some redecoration works to ceilings and walls to make good paint finishes around luminaires and electrical distribution boards where items are removed and either not replaced or replaced with an item which is of a different size. Every effort will be made to minimise the extent of this work, but it is perceived that high level redecoration around luminaires is inevitable as the new luminaires are of the more energy efficient are of the shorter T5 lamp type. New paint finishes will match the existing. It is proposed that these redecoration works be undertaken as and when works to each area are completed. They will involve high level access and equipment required for the electrical package works will be readily available for use.

1.7 SCALE

1.7.1 General The proposed works will not increase or decrease the size of the existing building size or layout. The proposed works are for the upgrade of the internal electrical services only and the scale of new items of equipment will generally be of the same size or slightly smaller.

1.8 ACCESS

1.7.1 General All the proposed works are of an internal services nature only and therefore no changes to the existing access provision to the premises. A proportion of the works will be undertaken out of hours to limit any disruption to the normal workings of the library.

each of the roof spaces. Wiring will be surface fixed white cable from a PVC single circuit drawn within the existing conduit system from the local DB below. Access gained from roof top.

Item d – Library area Item e – roof voids It is proposed to utilise the existing cable management and containment system where possible and include for modifying and extending it as necessary to service the proposed new lighting schemes. Any necessary extensions to the existing wiring systems are to be agreed with the Project Manager prior to proceeding with 1st fix.



1.3.2 Type ‘A’ Luminaire suspensions The Type A luminaires are to be generally suspended at 1.0m below the ceiling, with the exception of the 1st floor area 26A vaulted ceiling where provisionally fittings are to be suspended at between 1.5m – 2.0m below the ceiling (to be agreed on site.) Refer to Section 2 - for details on the Type ‘A’ fitting installation and suspensions. Flexible cable lengths to luminaire suspensions will be kept to a minimum. Any redundant ceiling boxes will be blanked off with white PVC blank plates.

1.3.3 Wiring systems Wherever possible any existing cable management/containments systems will be reused in order to avoid/minimise any damage to the building fabric and finishes. a. Basement book store 46 and adjacent offices, stores, rear staircase (all floors,) and all

staff facilities at Ground, and 1st floors – utilise the existing surface mounted trunking and conduit installations, modifying or extending the system in steel or PVC conduit as the existing system to accommodate any additional fittings/switching.

b. Main Entrance, Issues/Rets, Recordings and Shop (areas 02, 04, 06 & 08) – to the main

entrance 02 utilise the ceiling void with any surface drops in PVC conduits. To 04, 06 & 08 utilise the existing insitu conduit and surface trunking/conduit installations, modifying or extending the system in white PVC trunking and conduit as necessary to accommodate any additional fittings/switching. The Type ‘A’ luminaires will require to be fitted at new centres, with white PVC blank plates fitted to redundant conduit boxes.

c. Main staircase from basement to 1st floor (areas 55, 16, 57 and 22 Foyer) – utilising the

existing insitu conduit system. Additional cable containment is to be white PVC conduit. d. Ground floor main Library area 09 – utilise the existing surface mounted trunking and

replace the existing conduit install with new white conduit provide conduit box spacing’s to suit the suspension centres of the new fittings. These areas of ceilings will be redecorated.

e. 1st floor main library areas 26A, B and C and associated roof void – utilise the existing

insitu conduit system. The Type ‘A’ luminaires will require to be fitted at new centres, with white PVC blank plates fitted to redundant conduit boxes. The lighting installation within the 26A roof void area above will be undertaken in surface white cabling.

f. 1st floor rear library area 30 and associated roof void – utilising the existing insitu conduit

system. The lighting installation within the roof void area will be undertaken in surface white cabling.

g. Grd floor generator room, Lift lobbies at Bsmt, Grd & 1st floors, and roof level lift plantroom

(areas 44, 10, 11, 56, 27, 28 and 901) –galvanised steel trunking and conduit to generator plantroom, PVC/PVC multicore concealed within the ceiling voids and contained within white PVC conduit for droppers to wall mounted accessories for lift lobbies to bsmt, grd and 1st floors.



h. Side Staircase areas 17, 58 & 59 – utilise the existing surface mounted trunking and

conduit installations, modifying or extending the system in steel or PVC conduit as appropriate to accommodate any additional fittings/switching.

It is to be noted that there are areas of the premises that new surface mounted cable management/containment or surface cabling/wiring will be required. This will be undertaken in white PVC mini-trunking a similar way to the existing installations. Any deviations are to be agreed/determined on site with the Project Manager approval prior to commencing works.

1.3.4 Accessories New light switching accessories will be provided as necessary. These will be constructed and finished as follows:-

• Brass finish flush or surface as existing to Public Library areas.

• Grey/silver metalclad construction with stainless steel faceplates to surface installations back of house/staff areas.

Existing flush and surface mounted accessory boxes will be reutilised to minimise damage to building finishes. Ant new accessories in close proximity to existing shall be installed on a common horizontal centre line.

1.3.5 Visual impact of works To minimise any works to or on the building finishes, the proposed lighting upgrade to the public areas will utilise as far as practical the existing wiring containment system. The most visual difference is that the proposed luminaires will in the main be suspended as per the above illustration for the Glamox C-20 luminaire. It is to be noted that to minimise any damage to the 1st floor ceilings the existing containment must be clear for reuse. This is especially so for the vaulted ceilings to areas 26a & 26b. Should this not be the case then the careful installation of new cable containment will need to be considered.

1.4 Fire Alarm system

1.4.1 Scope of works The existing manual fire alarm system is to be replaced with a new part wired and part wireless addressable fire alarm system employing wired and wireless detection devices. The system is to comprise of:-

• Main fire alarm panel located to the main entrance of Abington Street.

• Fully functional Repeater panel located at the ground floor lift lobby.

• Both hard wired detection and sounder devices and wireless detection devices to locations.

• Translator unit for the wireless devices. • Interface units to gas solenoid, access control systems,

basement vent system, 1st floor extract fans and lift installation.



Location of main panel

The location of the main and repeater panels and all detection and sounder equipment is detailed on FKH drawings 3797/E-07, 08 & 09.

1.4.2 Wireless devices The detectors to ceilings in the open library areas and within the two roof voids above are to be of the wireless type monitored via Translator units wired to the new fire alarm system. Three Translator units are required and these will be located to back of house/staff areas, one to Grd floor Entrance - 02, Mezz floor Cloaks - 15 and 1st floor office - 32.

1.4.3 Wiring systems The fire alarm system is to be wired using low smoke (LSOH) cables coloured red. Cabling principals are generally as follows:- a. Public areas (i.e. library areas, main staircase etc.) - Surface cables contained within

MK/Ega Red Alert coloured “white” PVC mini trunking system. These cables are to be fixed inside the mini-trunking system with proprietary steel clips. Suspended ceiling voids will be utilised where possible to minimise the use of mini trunking (i.e. main entrance, basement library and lift lobbies.)

b. Staff areas (i.e. staff areas, basement area, side and rear staircases etc.) - Surface cables

with screw fixed PVC coated wrap around “P” clips. BGU’s and sounders to be surface fixed, detectors are to be mounted on galvanised steel conduit boxes.

1.4.4 Access control systems A number of doors to staff only areas are fitted with access control. These doors are to be interfaced with the fire alarm system to ensure that they fail open/safe in the event of fire alarm system activation. The works will include for providing an interface unit adjacent each to the controllers and for interfacing them with the access control systems. This work is restricted to back of house/staff side staircase areas.

1.4.5 Basement ventilation system control The basement discovery area - 40 has a ventilation system consisting of two ducts incorporating smoke dampers that close the fire alarm system smoke detection is activated. This ventilation system is to be connected to the new fire alarm system via an interface unit, and works will include the removal of the existing obsolete Minerva fire detection system and associated wiring. The Contractor will carefully remove the redundant equipment and wiring back to the basement lift lobby door. Minimal redecoration is planned to make good any equipment and wiring fixings.



1.4.6 1st floor extract systems The two high level extract systems to 1st floor library 26A and 30 are to be interfaced with the fire alarm system so that they are shutdown in the event of a fire alarm. Works include the modification of the extract fan control wiring and the installation of a fireman’s switch which will be located adjacent the distribution board DB9 outside the existing timber electrical cupboard at 1st landing.

1.4.7 Removal of existing system Upon completion and handover of the new fire alarm system the existing system and associated visible wiring will be removed providing that its removal does not cause unsightly marking of the existing finishes. Where the removal of existing wiring creates the need to redecorate, its removal is first to be approved by the Project Manager. Any existing flush mounted redundant breakglass call points will be left insitu and fitted with white moulded blank-plates so as not to disturb building finishes.

1.4.8 Visual impact of works The proposed system will provide automatic detection to all rooms/areas and as so will involve the installation of ceiling mounted detectors throughout, with wall mounted break glass units and sounders. The visual implications are as follows:-

• Public area detection will be wireless so visual impact will be limited to the detector alone.

• Back of house automatic detection, break glass units and sounders will be wired, (in keeping with the standard of electrical services throughout these areas.)

• A cable loop/ back-bone is required to be installed between panels and translator units for the wired devices. This will be surface fixed to back of house areas and installed within surface mounted white PVC mini-trunking where visible in public areas (as existing wiring method for some electrical service to existing public areas/rooms.

Proposed cable routes are detailed on the associated fire alarm drawings.

1.5 Automatic gas shut-off valve

1.5.1 Scope of works The main incoming gas supply is to be provided with a means of emergency isolation via an interface with the fire alarm system. This supply enters the premises within a full height cupboard at the main entrance off Abington Street. The inline gas solenoid valve will be concealed within this gas cupboard.

Hyfi re

Hyfi re is an intelligent wireless fi re detection and alarm system, comprising a comprehensive range of fully addressable, battery-powered detectors, call points, sounders, beacons and interfaces. Communicating through a sophisticated wireless protocol, Hyfi re offers high reliability and rapid installation for buildings where a traditional hard wired system would be diffi cult or disruptive to cable.

The system’s cost competitive design also makes Hyfi re a viable option for new build applications, where visible surface clipped cabling is undesirable or the speed of the building programme supports the case for wireless.

The system is EN54 part 25 compliant; the European standard for wireless fi re systems and operates at a frequency of 868MHz.

All wireless fi eld devices are battery powered and operate on freely available, low cost 3v lithium batteries. The status of all batteries is continually monitored back at the fi re control and indicating panel to allow the user to pre-plan the device battery replacements.

The wireless devices are complimented by an equivalent range of hardwired fi eld devices. The Hyfi re system can provide either a completely wireless solution or a hybrid system combining wireless and hardwired devices forthe ultimate in installation fl exibility.

• EN54 part 25 compliant

• Highly secure andreliable transmission

• Fast, simple andeconomic installation

• Low battery replacement cost

Control Panel & Wireless Modules

At the heart of the Hyfi re system is the control and indicating panel. The MX range of control panels is EN54 parts 2 and 4 certifi ed and availablein a range of sizes from 1 to 8 loops together with a networking capability to allow scalability of thesystem for larger applications.

The control panel integrates with the wireless fi eld devices via Translator Modules connected to the addressable loops which each manage up to 32 wireless fi eld devices. Multiple Translator Modules can be connected to and powered by eachaddressable loop to increase the system size.

A further wireless Expander Module allows thesystem to communicate with devices over greater distances from the Translator Modules and in diffi cult radio environments. Each Translator Module can support up to 7 Expander Modules. These units will relay radio signals from the fi eld devices to the Translators to ensure even remote locations can still achieveradio connectivity without loss of signal strength.

Wireless Detection Devices

The detector range includes optical smoke, heat and multi-sensor all with adjustable sensitivity settings to ensure a tailored solution is available to suitany application.

The multi-sensor is a combined optical and heat detector incorporating advanced algorithms to reliably determine the alarm status by analysing both the optical chamber and temperature sensor before taking a decision.

The optical smoke detector incorporates a double dust trap to protect the smoke chamber from airborne contamination together with a dust compensation algorithm to stabilise its sensitivity between routine maintenance visits.

Temperature compensation guarantees steady and reliable operation of the heat detector in low and high temperature limits.

All of the detectors have a stylish low profi le appearance with a simple two piece assembly for a quick installation. The option of a bespoke fi nish enables the detectors to be even less noticeable when installed in heritage sites or other premises where the integrity of the overall appearance has to be maintained.

Wireless Alarm Devices

The Hyfi re wireless alarm devices offer both audio, visual and combined units to provide a warning solution for any application. Both the audio and visual products are available as wall mounted or base mounted for installation with a detector. Colour variants and weatherproof options are also available.

To accommodate the ever increasing requirement for voice evacuation, the VSK voice sounder has programmable voice messages for warning and evacuation situations.

Wireless Interfaces

Specialist alarm systems and plant controls can all be coordinated with the Hyfi re system through this multipurpose array of wireless input and output interfaces. A special zone interface allows the system to integrate with conventional detector zones.
