2 ... NATURAL DAYLIGHTING Glidevale market a range of natural daylighting products including tubular rooflights, conventional rooflights, combined rooflight/ventilators and hybrid lighting systems. Advantages Highly effective at delivering light into internal and badly-lit spaces without windows. Energy saving - reduces the need for artificial lighting and helps reduce carbon footprint. Wide range of applications - houses, flats, schools, hospitals, commercial, industrial buildings, care homes, nursing homes and student accommodation. Suitable for both new-build and refurbishment projects. Meet the thermal requirements of the latest building regulations. Hybrid natural and artificial lighting solutions. Sustainability The sun is a sustainable light source, and natural daylight can make a significant contribution to sustainable building design. Rooflights are an effective and efficient means of maximising natural daylight in dark areas, often virtually eliminating the need for supplementary electric lighting during the day. Glidevale natural daylight systems, used as a complement to artificial lighting, can considerably reduce the annual energy consumption of any building, thereby reducing CO 2 emissions. Proven benefits of natural light Scientific studies have shown the positive benefits of natural daylight for health and wellbeing in a range of applications. The CIBSE Office Lighting Guide states that Natural Daylight is an almost universal worker requirement. When given a choice, most people prefer a working environment with daylight to one without. It references documented evidence confirming that excluding daylight leads to increased numbers of complaints about the working environment, and may adversely affect productivity. The Daylight Workplace Regulations state that The lighting in every workplace shall, as far as is reasonably practical, be by natural light. BRE Environmental Assessment Method The benefits of natural daylighting are recognised by the Building Research Establishment (BRE) Environmental Assessment Method (BREEAM). BREEAM Modules cover Schools, Offices, Healthcare, Retail and Industrial buildings. These buildings are then rated on a scale of PASS, GOOD, VERY GOOD or EXCELLENT. Glidevale natural daylight systems can contribute to the credits available under the Health and Wellbeing Section HW01 and the Energy Section E

3 PRODUCT RANGE Sunscoop tubular rooflights Used to bring natural daylight into internal rooms and spaces that have no, or insufficient, windows.

5 SUNSCOOP TUBULAR ROOFLIGHT SYSTEMS Internal view of different diameter tubular rooflights under test External lux sensor with shade ring for measuring diffused light levels Monitoring of three tubular rooflights simultaneously PERFORMANCE Unique test programme The performance of the Sunscoop Tubular Rooflight system has been firmly established by a unique and extensive period of testing, unparalleled in the tubular rooflight industry, carried out by Silsoe Research Institute (SRI) and BPD. Measurements were taken over four to six month periods during the summer/ autumn in all natural light conditions ranging from bright clear skies to overcast conditions. This comprehensive monitoring has for the first time provided accurate, realistic and reliable performance data for tubular rooflight systems including direct and diffuse lighting conditions. The research is subject of a published paper entitled Optimisation & design of ducted daylight systems: 2010 which is specific to Glidevale systems only. Typical light levels The light output from the Sunscoop system depends on the size and length of tubing, offset angles if any, the external sky conditions and light levels measured in lux. The distribution of the light in the room depends on the diffuser type and the wall, ceiling and floor reflectances. A sophisticated in house computer programme has since been developed to accurately predict light levels of Sunscoop systems, based directly on the SRI and BPD monitoring. System layout Sunscoop systems can pass through a roof space or other void. For maximum effectiveness the tubing should be as straight as possible. However, since it is often impractical to site the ceiling diffuser directly below the roof-mounted glazing, the tubing system allows an offset by means of an elbow. It is adjustable up to 30º from vertical. Other elbows can be used but monitoring has shown that these will adversely affect performance. Siting Where possible the roof-mounted glazing should be located on a south-facing slope to gain the maximum amount of daylight under both direct and diffuse conditions. Factors which need to be considered when siting a Sunscoop include: - Location of the room to be lit and suitable position of the ceiling diffuser. - Roof space obstructions. - Proximity of other buildings, trees etc, which may cast shadows at certain times of the day or year

8 SUNSCOOP TUBULAR COMPONENTS Roof-mounted glazing Sunscoop glazing is manufactured from 3.0mm clear uv-stabilised polycarbonate with 92% light transmission. The glazing is available in two types; Square dome fitted to a builders kerb or supplied insulated upstand. Traditional skylight fitted within tile and slate coverings. For further information see page 7. Both have a 10-year warranty (supported by the polycarbonate manufacturer) against loss of impact strength, excessive yellowing and loss of light transmission. Tubes and elbows Tubes and elbows are anodised aluminium with a multi-layer specular coating which ensures pure white light with no colour shift, even after multiple reflections down the light tube / shaft. The material called SR98 Mirror incorporates a pure super silver layer and has a total reflectance of 98%. Anodised aluminium base material Bonding layer Pure super silver or pure aluminium layer Super reflective (LR) oxide layer Super reflective (HR) oxide layer The warranty also covers any effects of the forming process. Not all manufacturers offer this warranty. Polycarbonate secondary glazing is also available to maximise insulation levels along with the use of tube insulation (supplied separately). The multi-layer optical coating system is atomically bonded to the substrate. Laminated or glued reflective sheets are not used. It has a 25-year product warranty which guarantees that the material will not splinter, yellow, darken, peel off, blister, crack or develop any other surface degradation which could reduce overall reflectivity, even after prolonged uv exposure. The finished materials are electrostatically neutral and will not attract airborne dust even during installation. Low profile glazing on plain tiles Low profile glazing on slate pitched roof Sizes Tubular systems diameter: 250mm, 350mm, 450mm, or 530mm. Starter tube length: 300mm. Elbow adjustment: up to 30. Intermediate tube: 600mm. Can be cut as required on site

9 Integral electric light fitting The Sunscoop can be supplied with an optional integral electric light fitting (two on 450 and 530mm systems) which takes a 13W or 20W low-energy lamp (equivalent to a 65W or 100W conventional lamp). This avoids the need for an additional light fitting for night-time use. Light-attenuating dampers Control over the light level entering the room may be required at certain times, for example in conference rooms, lecture theatres, classrooms and hospital wards. Ceiling diffusers Circular ceiling diffuser The standard recessed ceiling diffuser for all tube sizes, designed to maximise light transmission. Its translucent surface provides privacy and spreads the light efficiently throughout the room. Manufactured from diffused polycarbonate with white-capped ABS ceiling ring to hide fixings. Also available in chrome or brass effect finish. The optional Sunscoop motorised lightattenuating damper provides this control; it is actuated from a wall switch, separately available. Fire protection collars In longer Sunscoop systems the tubing may pass through an intermediate floor or ceiling that provides fire separation. As with any ducted system it is important that it does not form a path for fire. Fire protection collars providing up to 120 minutes fire resistance to BS 476: Part 20: 1987 are available for all sizes of Sunscoop Tube Insulation (supplied separately) Specifically designed to contribute to the overall thermal performance of the system. All exposed tubes and elbows within unheated voids should be lagged with tube insulation to reduce heat loss and the risk of condensation within the tube. Thermal insulation Our Technical Services Department can provide computer calculations of U-values in different roof constructions using Sunscoop rooflights, including the use of secondary glazing skins and/or tube insulation, to comply with Building Regulations Part L Skyview diffuser, circular Optional for all tube sizes. The innovative Skyview diffuser consists of a grid of fresnel lenses which provides a wider spread of light without excessive losses and enables the sky to be viewed. Skyview diffuser, square Optional for 450mm and 530mm tube only. Similar to the circular Skyview but mounted in a 600 x 600mm polycarbonate panel which can be fitted in a suspended ceiling

10 SUNSCOOP ipsv COMBINED LIGHT &... VENTILATION UNIT The Glidevale Sunscoop ipsv system is designed to provide both natural daylight and ventilation to bathrooms, toilets, kitchens, en suites and other similar areas, in both domestic and commercial applications. Natural daylight enters through a roofmounted glazing unit and is reflected down the highly reflective tubing through a Skyview ceiling diffuser. This innovative diffuser consists of a grid of fresnel lenses which provides a wider spread of light without excessive losses and enables the sky to be viewed. Ventilation is controlled by the intelligent extract operated by a series of nylon bands, which respond to humidity levels and regulate the size of the air opening. Flexible ducting (support and insulation omitted for clarity) TT9 Versatile tile ventilator Utilising a separate ducting system allows optimum performance from both units - the shortest possible length to maximise natural daylight through the ceiling diffuser and a separate duct for the extract to optimum length for the stack effect. Low profile glazing on Universal tile flashing SR 98 Mirror reflective tube guides daylight down to the ceiling diffuser (insulation omitted for clarity) Key features No electrical connection or power source is required so the system is naturally energy efficient. Intelligent humidity controlled extract responds automatically to changes in relative humidity giving greater ventilation when humidity is high whilst preventing unnecessary ventilation and heat loss when humidity is low. 24 hour condensation control with gentle extraction - operates all day and every day as required combating condensation and mould growth. Completely silent in operation. Complies with the requirements of Approved Document F. Minimal maintenance - no mechanical components to go wrong. No costly solar panels or battery backups. Automatic response and no operating controls, ideal for special needs applications. Tests by Building Research Establishment (BRE) have shown an intelligent passive stack system incorporating a humidity sensitive extract gives a 15-40% saving in ventilation heat loss dependent on occupancy levels. Thermal modelling by De Montfort University has shown that the intelligent passive stack system operates effectively even in summer months and internal bathrooms. The research also demonstrated effectiveness even in very airtight dwellings. Can be supplied with optional integral electric light fitting which takes a low energy bulb to avoid the need for additional light fitting for night time use. Size 250mm diameter Sunscoop Ventilation unit area provides 12,270mm 2 at maximum humidity with 125mm ducting. Ceiling (insulation omitted for clarity) Combined extract ventilator and Skyview diffuser

11 SUNSCOOP HYBRID The Sunscoop hybrid is a 350mm unit with a daylight controlled dimmable low energy compact fluorescent luminaire integrated into the ceiling diffuser assembly to provide a more consistent light level despite changing external daylight conditions. The CIBSE Lighting Guide 10 - Daylighting states that: Case studies have shown that in a conventionally daylit commercial building the choice of control can make 30-40% difference to the resulting light use. The Sunscoop hybrid has a control unit which controls both occupancy and daylight levels, maximising the energy savings from lighting. Key features The Sunscoop hybrid incorporates a light sensor which is programmed to turn on when the light level inside the room drops below a certain level. Luminaire turns on with optional soft start, allowing a gradual increase in light output and adjustment to the required level. The Sunscoop hybrid incorporates a lighting controller, lux sensor and PIR presence detector. When the unit determines there is adequate natural light available, the lamp is automatically turned off. When light levels fall, the lamp is switched back on and its output continues to be regulated by the daylight sensor. The programmable PIR presence detector will turn off the lamp when the space is unoccupied irrespective of the light level. Ceiling Diffuser / Luminaire The unit comprises a 350mm standard diffuser with option for Skyview type. The adjacent luminaire features a white powder coated spun aluminium bezel and a diamond faceted vacuum metallised aluminium reflector housing a dimmable 26W compact fluorescent lamp. Sensor and control gear are pre-fitted. Sizes 350mm diameter unit contains one downlight, which at full capacity produces an output of 1800 lumens. Appearance White ABS ceiling diffuser ring to encompass both Sunscoop diffuser and downlight assembly. Performance The sensor which is looking directly downward continously monitors the light level reflected back to the ceiling and regulates the output of the compact fluorescent lamp to maintain an approximate pre-determined light level.

13 METRODOME MODULAR ROOFLIGHTS Roof interface Glidevale rooflights can be supplied for fitting either directly on the roof deck, or on a builder s kerb (usually made on site). In new build, an integral upstand is the favoured choice as it provides a prefinished internal skin and an exterior to accept the roof covering. In refurbishment, a builder s kerb will often already exist. Upstand Metrodome is supplied with an integral upstand for fitting directly to the roof deck, or with an additional weathering flange at the base of the upstand for fitting to a builder s kerb. The upstand is manufactured from double skin mill finish aluminium with an insulated core, mitred and welded at corners. The internal face is finished white for maximum light reflectance. Glazing Triple or double skin polycarbonate with vented air gap, in extruded mill finish aluminium frame with mitred and welded corners. Available in clear, diffused or bronze glazing in dome or pyramid shapes. The glazing comes with a 10 year postformed warranty supported by the polycarbonate manufacturer against loss of impact strength, excessive yellowing and loss of light transmission.

14 METRODOME MODULAR ROOFLIGHTS Thermal insulation The insulated upstand and double or triple skin glazing, with vented air gap, give good thermal insulation and minimise the risk of condensation. The overall calculated U-value for a 600 x 600mm unit with triple glazing and upstand is 1.99W/m 2 K. Glidevale Technical Services Department can provide computer calculations of U-values for given rooflight sizes in different flat roof constructions to comply with Building Regulations Part L The calculated U value will vary with the size of rooflight, due to the changing ratios of upstand, glazing and frame area. Internal and external fire spread (B2/B4) The internal surfaces of the rooflight upstand and frame are non combustible and would achieve a Class 1Y rating when tested to BS 476: Part 7: Polycarbonate glazing a minimum of 3.0mm thick with a Class 1 rating is deemed by Building Regulations Approved Document B4 to be rated AA. Metrodome rooflights can therefore be used without restriction on size or spacing in all types of room and circulation space, except protected stairways. METRODOME ROOF ACCESS HATCH Description Metrodome Roof Hatches provide access to a roof from inside a building. The construction is similar to the standard rooflight but the top opens to 90 and is supported by twin slip and stick gas struts. Tops are available either glazed or insulated aluminium. An internal latch retains the top when closed and can be secured with a padlock (not supplied). These units are not available for builder s kerbs. Size The access hatch is available in the following sizes: 900 x 900, 1050 x 1050, 1200 x 900 and 1200 x 1200mm.
