Relighting of Bessels Green Baptist Church Hall,

Meeting Rooms and Crèche.

Introduction The hall is used as a multiple purpose room with events ranging from family "get together's" to art classes. The previous lighting could not provide the required levels or give the flexibility to meet these requirements; additionally the lack of luminaires in the area around the roof lights resulted in poor uniformity over the working plane. The decision was made to renew the lighting and we were called in to prepare a lighting design.

The Lighting Proposals. To meet the diverse requirements of this area a lighting level of 500 lux with Colour Rendering of Ra 80 was selected. This was considered to be sufficient for the art work undertaken and by using luminaires with regulating control gear the lighting level can be reduced for the less demanding tasks. One end of the hall can be fitted with a stage, consequently the lighting was installed on two dimming circuits, one over the optional stage and the other for the remainder.  The playing of handball or soft ball in the hall limited the choice of luminaires as those with parts which would pose a risk of becoming dislodged if hit with a ball were unacceptable. The staggered installation of the ceiling tiles and many roof lights made the design of a symmetrical layout difficult. Some symmetry was achieved by using recessed downlighters with 2 x 26 watt PLC Colour 830 lamps. On occasions the hall can also be used for exhibitions or displays and the design therefore included nine short lengths of track with a limited number of spotlights which could be fitted for such events.


Meeting Rooms and Crèche.   There is insufficient depth above the tiles for recessed luminaires in these rooms and as they also have very low ceilings slim surface mounted luminaires were installed. The diverse usage of these rooms required a lighting level of 300 lux again being controlled by a dimmer so that the correct ambiance can be achieved.

The Lighting Proposals

The parameters for the new design were to:-

The lighting scheme was designed to provide a lighting level of 200 lux in the Nave raising to 500 lux in the Chancel. The up-lighting is switched separately from the  direct lighting so that when a service is not being conducted the up-lighting can be used to light the Church. The decision was also made to include emergency lighting and to avoid more luminaires being used, a central battery system was proposed using selected direct lighting luminaires.

In more detail

Up lighting

To up light the ceiling throughout the Church, Philips Color Kinetics eW Fuse Powercore 3000k medium beam luminaires were specified which have an ultra compact form factor which allows it to be installed in tight spaces. These were mounted just above the frieze and directed towards the opposite side of the vaulted ceiling, and provide an average illumination level of 65 lux on the working plane.

Down lighting

A combination of track mounted Philips StyleID Performance 3000K and Mini 3000K have been used to provide down lighting in areas across the Church, including the Chancel, Side Chapels, Transepts and Nave.

Recessed Philips LuxSpace down lighters fitted with a diffusing lens have been used in the Lobby, Nave and under the balcony.

Sanctuary Lighting

It was decided that the Sanctuary wall needed to stand out and be more of a feature. To achieve this, an RGB colour changing solution from Philips Color Kinetics was specified and installed. The iColor Cove MX Powercore is a high intensity LED fixture that provides vibrant coloured light.

Control of the Sanctuary coloured lighting system is by means of a ToBeTouched colour wheel, which allows the Church to select the colour required.

Comment from Father Martin Jakubas, Parish Priest of St Paul’s “Our new lighting scheme had exceeded our expectations.  The move from a small number of aging suspended chandeliers to modern, well positioned equipment has enabled us to take full advantage of the various lighting scenarios which we wished to develop.  An unexpected benefit has been that removing the chandeliers has completely changed the visual and sound dynamics of the church solving some problems that we didn’t even know we had.  We are very, very pleased with the work that Andrew and the installation team have done for us.  It is attracting a lot of attention from other churches in the diocese of Arundel and Brighton.”

Background

The general lighting of this church was by means of chandeliers suspended in the nave with some High Pressure Sodium up-lights mounted close to the ceiling line. Additional spotlights and floodlights had been added in various places to provide additional light. The lighting was looking rather dated and was not providing sufficient light in places for reading. In addition one of the shades on a chandelier had been broken and could not be replaced, many of the up-lights had failed and the lighting system was looking “tired”.  (See picture right)

The decision was made to renew the lighting and we were asked to prepare a design.

Relighting of the Old Hall in Eye Town Hall, Suffolk.

This Victorian Hall is a Grade 2 listed building which has just finished renovation. Previously it was lit by fluorescent luminaires fitted with industrial reflectors suspended from the high ceiling. These detracted from the architectural qualities of the room, were difficult to maintain because of the high mounting height and were switched making changing the ambience of the room difficult.

The Eye Town Council decided that the relighting of the area was necessary and asked us to prepare lighting proposals.

The brief was to provide a design which would:-

These requirements dictated that:-

The choice was made to use Philips DALI dimming LED spotlights fixed to the beams just below the roof windows and finished black so that they blended in with the dark wood It was also decided that the area should be controlled in three zones giving the lighting result greater flexibility. In keeping with fire regulations an emergency lighting scheme was prepared that ensured that a minimum lighting level of 0.5 lux was achieved over the area. Exit signs already existed and did not need tp be replaced.

In the autumn of 2016 an Electrical Contractor was appointed. It was decided that the two luminaires which had been used for a trial were also to be used one being mounted at each end of the hall. The original proposal had been for three separate circuits to be run to the roof space but it was found that getting an electrical supply through was so difficult that it would be cheaper to provide one circuit and using the DALI system to switch and dim the luminaires in the three zones. This had the advantage that the areas could be reconfigured at a later date without changing the wiring should it be necessary. A single neat switch panel was installed in place of the three dimmer switches and configured using the Philips Dynalite user interface to provide simple dimming options. The Hall was handed back to the town Council in October 2016 and we have heard that the results have been well received by everyone.  

Further requirement to light the roof space.

Part of the redevelopment of the hall included a total renovation of the hall roof. It was always considered that lighting of the roof space would enhance the appearance of the hall and further design work was undertaken. Luminaires from the same range as those used for the general were included and were mounted just above them.  

The renovation has now been completed and on the 30th October 2018 the hall was officially re-opened  for use by the Residnts of Eye and the surrounding villages.

Previous Lighting

Preparing for the official opening of the refurbished Hall

Women’s Institute Hall – Tatsfield, Kent.

This hall meets the criteria of what are known as “Tin Tabernacles” which were built from the mid 19th to early 20th century as churches. There are a number of these still around this country and some overseas all comprising a wood frame, internally lined with tongue and groove boarding and clad in galvanised corrugated iron.

This hall was donated to the Tatsfield Women’s Institute in 1935 and they still use it for their meetings as well as hiring it out to those in the village for an art group, yoga sessions and other functions. They have been responsible for the maintenance of the building and decided that the lighting needed replacing as the fixings of the diffusers of the fluorescent luminaires were broken and were in danger of falling.

The assistance of Lighting Design and Drawing Services was requested and various proposals were submitted and a scheme replacing the existing luminaires on a one for one basis using JCC Lighting Ltd Skytile luminaires was selected. These use a LED panel which combines a very uniformly lit appearance with energy efficiency and resulted in the lighting level being increased with a reduction in the electrical load.

As none of the Members were au fait with the Electrical Contracting business a degree of product management was undertaken by Lighting Design and Drawing Services in that the specification for the installation was prepared and various local Electrical Contractors were asked to tender. The Contractor was selected by the WI Hall Management committee and Northway Electrical Services were appointed. After completion a number of members commented that the new lighting has greatly improved the appearance of the hall one stating the “the new lighting is blooming marvellous”

Security Lighting.

The security lighting at this school is required to illuminate an area around the perimeter of the buildings and communicating paths. Until its replacement the lighting had been in operation for a number of years and used old technology which had reached the point where additional maintenance/replacement was required. In general circular bulkhead luminaires using 2D lamps had been used around the site. When these are mounted on a wall at least 50% of the light is directed upwards and hence wasted and is of course creating light pollution. These luminaires were mounted at a height of approximately 1.8m consequently they acted as a glare source, making it more difficult to see the way ahead.

We were approached to provide a replacement lighting solution using luminaires with LED sources as they have the advantages of very long life, low running costs and next to zero maintenance. The majority of the areas to be lit are only used by pedestrians consequently these have been lit to a level of 5 lux however in the entrance area slow moving vehicles are permitted and because of the increased risk to pedestrians the lighting level has been increased to 10 lux. To aid evacuation in the case of a power failure or emergency all the luminaires are fitted with emergency back-up ensuring that the children and staff can leave the building safely.

The lighting proposal was submitted and after consideration by the School Governors the decision was taken to proceed with the scheme; a check was made of the practicability of mounting the luminaires in the position proposed and adjustments made to ensure solid fixings and to meet the Listed Building requirements.

Normal tendering procedures were followed and Pro-Care Electrical Services of Watford were awarded the Contract. During the summer break the lighting was installed and the school are delighted with the results as the lighting on the site has been significantly improved.
