EDUCATIONAL EDUCA TIONAL LIGHTING ‘ Studies in primary educati on have proven a connection between light quality in a classroom and the academic performance of children ’

much has een witten aout the iotance of light in educational envionents. Studies in iay education ( Wot. W ot. 1986, h & Tompo.1989 & htwy.1994 ) htwy.1994 ) have found a connection etween the quality of light in a classoo, the well-eing and acadeic efoance of the childen. Anothe significant study ( hco h co Mo.1999 ) ) showed a stong link etween daylight and acadeic achieveent. A good guidance docuent – bb90 Lighting Design fo Schools – was ulished y the DFEE in 1999. Howeve since its ulication oe ecent eseach ( B. B . 2001 & at. 2003 ) ) has undelined the vital ole of light in iology and ental efoance. High colou teeatue light that is ich in shot wavelength (lue) sectu has een found to oost oth well-eing and cognitive e foance fo woking duing the daytie. The iological echaniss involved ae now undestood and oven. The conclusion fo all this study is that significant enefits can flow fo inceasing levels of natual and atificial daylight esent in schools and univesities.

We now know that cognitive and visual efoance inceases with light level and colou teeatue, so long they ae also low in glae. This knowledge should have ilications fo secifying lighting conditions in exa halls. Juslen ( ‘Pp ‘ Pp t’ 2004 ) ) has suggested secifying highe light levels acoss ost teaching sace than cuent guidance, howeve we ust also e indful of enegy consevation. Intelligent lighting design has little difficulty in econciling these two equieents, ut the selection of lowest cost fittings will often e the ain ostacle. Cleavision ovides design and consultancy sevices to assist in c eating egonoic and envionental uildings that will suot the est enegy and acadeic efoance. This anual is intended as a guide into the tyes of saces and fittings that could e alied to achieve these esults. We hoe that this infoation will assist in the ceation of ealistic udgets caale of deliveing the ette lighting that the est education needs.

COnsideraTiOns : The contiution a well lit classoo akes to educational achieveent should not e undeestiated. Half of all sujects in seconday schools and vitually all sujects at iay schools ae taught in these saces. As classoos should e designed to take axiu advantage of availale natual light, the electic lighting installation should oth haonise with any daylight, whilst also coensating fo its vaying availaility. Fo this uose Cleavision ecoend the use of cool (6500k) ‘daylight’ fluoescent las, which studies have indicated, also ioves oth aletness and visual acuity.

Ceiling, and aticulaly wall oo sufaces, should e well and evenly lit, without oducing distaction factos, such as excessive contast o glae. In this way a sacious, stiulating inteio can e ceated with ehasis laced on whiteoads, wall dislays and desk sufaces. Fo these easons the use of luinaies with an aut light cut off at highe angles, aticulaly louved oducts, tyically secified fo use in offices whee dislay sceens ae evalent, should e avoided. This aoach will usually esult in a cave-like effect of dak ceilings and ue walls, which is oessive and unleasant to occuy.

COnTrOls : As previously mentioned, a well designed classroom should utilise any available natural light to its ullest. Thereore, to achieve maximum energy savings, any lighting controls should eature daylight regulation. A single photocell, usually integrated within the presence detector, detector, is sucient to reerence light level within the space, allowing the output o dimmable luminaires to be at the minimum required. The luminaires are usually controlled in rows parallel with the window, with it sometimes being sucient to limit control to just the rst window row.

Further energy savings are achieved by absence detection. Lights are manually switched on upon entering a classroom, but should they ail to be switched o upon exit this will automatically occur ater no movement has been detected or several minutes. Gradual dim down beore eventual switch o, to provide warning to any particularly still occupants is also possible.

Additionally, dimming luminaires via wall plate or handheld controller will provide optimal illuminance where varying light levels may be required or demonstrations, desk work or use o the interactive whiteboard. This is particularly o use in primary schools where a variety o activities are carried out in one space. These control interaces should be simple and i ntuitive, minimising teacher and pupil distraction.

When multiplied across a whole site the reduction in lighting energy achievable within classrooms can have signicant eect on a school’s school’s annual electricity spend.

Sensors can be integrated into the lighting, be recessed into ceilings, or be surace mounted i required.

COnTrOls : As with general teaching space, daylight linked dimming and absence detection eatures should be integrated into the control o the lighting in practical teaching space. Additionally, there is scope or urther energy savings via manual dimming and/or selection o preset light levels, o sa y 300 lux. This also adds fexibility where; only basic teaching

tasks are being perormed (requiring lower light levels) demonstrations are occurring, or projection/display equipment is being used. It may be desirable to provide the luminaires above the ront, lecturer bench, with a higher lighting level in order to add clarity and ocus to demonstrations.

COnTrOls : Full range dimming and scene setting unctionality will allow a lecturer to eortlessly alter the lighting conguration to suit any current activity. Smooth changes between scenes should be instigated by a single button press, without the audience disturbance abrupt switching may cause. The lighting control

panel should be located close to the lectern and/or a remote handset provided. Integration with any audio visual system will minimise teaching distraction.

COnTrOls : Full range dimming and scene setting unctionality will provide the fexibility to use the space or special events and also acilitate colour changing i required. Access to control plates and switches should be restricted. Regulation o luminaire output

with available daylight should be implemented where sucient natural light is available. The use o detectors within kitchen areas should be avoided as any drop in the lighting will have obvious saety implications.

The ost actical way to achieve this in coidos is via a cental ow of suface ounted linea luinaies oviding a wide distiution of light. Altenatively, two ows of ecessed downlights, laced close to the walls can e accoodated y the wide diensions of school thooughfaes.

Highe illuinance should e ovided to these saces, aticulaly whee liited natual daylight is availale, to aid the eye’s adatation etween intenal and extenal lighting conditions.

COnTrOls : Substantial energy savings may be achieved by implementation o presence detection in all circulation space. Due to requent and predictable shits in occupancy, i.e. between class times, dimming, rather than switching control o the luminaires is recommended or school buildings. Whilst excessive daily switching cycles will reduce the lie o both control gear and lamps, this issue is eliminated by dimming.

Luminaires within unoccupied corridors will gradually dim to 20% output ater a predetermined time period, returning to ull output once movement is detected. Standard dimming luminaires are now available with this control unctiona lity built in, minimising initial hardware cost. Once again regulation o luminaire output with available da ylight should be implemented where viable.

to these figues has een esonsile fo any ooly lit installations in the ast, esulting in inadequate wall and ceiling illuinance, the iotance of which is discussed in the ‘Geneal Teaching Sace’ section of this guide (See page 6).
