EDITOR’S COMMENT

Daylighting Magazine – one year on...

A year has passed since we launched our pilot issue at the end of 2016. What an eventful year it has been, with many national and international news events having a bearing on our industry.

The time has really come to put the value of human life first and to adopt the principle that safety must be prioritised over cost-saving.

The decision of the Trump administration to pull out of the Paris climate deal in 2017 has been a setback to meeting global emissions targets. However the response from may US mayors and other politiicans has been to draw up their own local climate initiatives, which may well result in a more positive outcome for the climate lobby. A silver lining, perhaps...

Needless to say, in 2018 we will continue to bang the drum for emissions reductions through more efficient building design.

Closer to home, Brexit has been the dominant topic in our domestic media over the last couple of months.

Lets hope, as we move forward into 2018, that lessons really are learned from the tragedy of the Grenfell Tower Fire.

2017 has been a year of major climate events which strongly appear to be connected to manmade climate change as reported

by most of the world’s media.

Let’s all hope that the key issues surrounding Brexit are resolved as soon as possible, to allow UK and European businesses to plan for the future with confidence.

UK rooflights market increased by 25% between 2012 and 2016

The UK’s rooflights market has seen significant growth over last 5 years, according to a study by AMA Research, as reported by Barbour.

The rooflights sector represents a strong performing but small portion of the overall roofing market, accounting for slightly under 10% of the roofing market by value. Since 2012, the market specifically for rooflights has shown strong growth year on year, increasing by a substantial 25% between 2012 and 2016, with similar growth expected in 2017.

These figures relate to standard modular rooflight systems widely used on flat roofs, which are supplied in many sizes and styles, and that are assembled on-site or delivered as prefabricated units to create barrel vaulting, bespoke or complex high-value roof / atrium glazing. Excluded in the analysis are opening

skylights and in-plane rooflights used on domestic pitched roofs.

Growth in the rooflight market is supported by a number of factors and trends within the roofing, building and home improvement markets in general.

In particular, an increase in flat roof construction has led to growth in the rooflights market, as well as home extensions and commercial property extensions.

A recent focus on improved daylighting has driven demand for flat roof windows in both residential and non-residential sectors, with private housing extensions a key area of application. Additionally, the development of new products, such as larger flat glass and “walk on” rooflights plus the upgrading of existing products with higher specification materials, e.g. triple glazing, has added some value to the market in recent years.

The supply of rooflights is quite fragmented with no one company holding more than 10% of the market in 2016, and as a result of the market seeing strong growth in recent years several new suppliers have entered the market. Furthermore, many existing suppliers have extended ranges to include more ‘non-standard’ products or new products aimed at ‘non-core’ end use sectors. There is evidence, however, that this expansion of the supplier base is providing negative pressures on average prices – this appears to be particularly relevant in online sales in the residential sector.

In terms of product mix, the total demand for glazed rooflights has increased year on year due to the uptake of premium products such as tripled glazed units and self-cleaning glass. Since 20132014, glass products have taken share with key uses being mid to higher specification “walk on” flat rooflights and panel glazing. The main commercial end use applications for these products are school buildings, leisure centres, indoor swimming pools, shopping malls/ arcade and transport terminals.

Thermoplastic products are also mainly used for commercial buildings with the main application being for barrel vaulting and domes on commercial buildings.

Corrugated or trapezoidal inplane GRP sheets are the other major product group, these are almost wholly used in factory, warehouse, transport, agricultural

Aluminium glazing enjoys ‘considerable resurgence’, according to industry report and horticultural roofing.

Overall, there are many varied key non-residential markets for manufactured rooflights.

Education represents the largest non-residential end use sector with an estimated 25% share by value, followed by industry and agricultural buildings and the leisure sector. The leisure sector contains within it many varied facilities from museums and galleries to swimming pools and indoor sport centres, while other major end use sectors include offices, transport buildings and retail buildings.

Looking forward, the strong growth experienced in recent years is not expected to continue in the short term. Reflecting the more challenging and uncertain economic climate ahead the market it is estimated that sales will stagnate from 2018 onwards, in line with the overall roofing market. In addition, while demand for housebuilding and housing RMI is high and will have a positive impact on the roofing sector as a whole, rooflights of this type are unlikely to be used in affordable or volume housebuilding.

A new report on the UK’s window industry by Insight Data has found that aluminium glazing has experienced a ‘considerable resurgence’ within the UK’s residential window and door market, as consumers ‘demand greater space and light within living areas’.

Data software firm, Insight Data published their overview of the UK’s window, door and conservatory industry, along with top performing companies, and found that the sector had experienced an increase of 328 firms operating in the marketplace since 2014.

The company revealed that in 2008, there were 2,370 PVC-U fabricators operational throughout the UK, but this number has declined significantly year-on-year and by 2014 had fallen by almost a third to 1,534 operational fabricators; due largely to the growth in demand for energy efficient aluminium designs for rooflights,

windows and doors alike.

According to the industry report, some companies had experienced an ‘unpredictable’ year to date, with some firms reporting a decline in sales of up to 15%. Nevertheless, other firms recorded more encouraging sales figures, particularly those manufacturing premium glazing products and working in commercial and new-build sectors.

The report also states that with interest rates still incredibly low, unemployment at a record low and consumers still spending ‘albeit more cautiously’, there are still plenty of opportunities in the industry despite the challenge of Brexit to contend with. It is also reported that Chancellor, Philip Hammond will announce further government stimulus in the Autumn Budget 2017 to improve house-building levels, helping to continue a drive towards low-carbon, energy efficient homes and glazing solutions that maximise energy performance.

Make Sure You’re Seen in The Right Light The need to produce energy-efficient buildings is a key consideration in today’s sustainability-focussed construction sector. John Godley, Technical Manager at Hambleside Danelaw discusses energy-efficiency in the ‘metal shed’ sector.

FACTORIES & WAREHOUSES

The need to produce energy-efficient buildings is a key consideration in today’s sustainability-focussed construction sector. Saving energy reduces the carbon footprint and makes a vital contribution in the drive for carbon-neutral buildings. It also saves money by reducing the running costs of the building.

When considering large buildings, particularly in the metal shed sector, the traditional targets of improved thermal performance and minimised air-leakage have now reached their optimum performance levels. Put simply, further increases in insulation levels now deliver limited benefit.

Specifiers and clients are becoming focussed on the significant contribution that can be obtained by designing natural daylight into buildings, and seeking the best rooflight solutions to deliver this free resource.

Depending on the type of lighting system installed, the cost of lighting a building can be more than ten times the cost of the heat saved by removing the rooflights. In many building designs, the cost of the lighting can be four times that of the heat losses when ‘light to heat’ balance has been considered. Even with low energy LED systems, this ratio can still be as high as three times. Accordingly, the daylighting plan is now becoming a principal consideration in the building envelope design and specification process.

The emphasis on this critical design aspect means that specifiers are now faced with a veritable haze of information and choices they can make on rooflight specifications.

Like every other component within the building envelope, rooflights must perform several functions:

www.daylightingmag.co.uk

• They must deliver good light transmission

Depending on the type of lighting • This must not create excessive system installed, solar gains the cost of lighting • They must deliver adequate heat retention a building can be • They must provide a non-fragile roof more than ten times assembly the cost of the heat • They must deliver a well-lit building saved by removing with the right kind of light the rooflights.

Not all these requirements are complementary. It is important to strike the right balance for each building design, and understand that there is no single solution.

It is also important to understand that there are laws of physics that cannot be changed. In glazing and glass reinforced polyester (GRP) rooflight systems, most of the heat energy from the sun is transmitted directly and in the visible spectrum. Plastics such as polycarbonate have more energy transmission in the infra-red regions and beyond. This means that it is simply not possible to deliver any system with an unachievable mix of high light and low solar transmission levels.

The same is true for specifications which adopt only some elements of a ‘holistic package’ design in isolation.

In the right building, it is sometimes possible to use smaller areas of rooflights than would normally be considered adequate, but these may be designed and intended for use in conjunction with additional offsetting renewable energy sources. Even using rooflights that deliver exceptionally high light transmission levels, poor distribution - or inadequate areas of rooflighting - can create uneven and unsatisfactory levels of light balance within the building.

FACTORIES & WAREHOUSES

Similarly, whilst the improved thermal performance of rooflights can reduce heat loss, the inclusion of increasingly numerous ‘clear’ insulating layers or cells can be counter-productive. Each layer or cell adds an additional light reflective surface into the assembly.

These cumulatively reduce the level of light transmitted into the building, potentially costing more than the small savings in heat retention.

There is no trade-off on non-fragility.

It is about safety and saving lives, and no-one within the specification chain has the right to gamble with it.

Rooflights can be made stronger by making the material thicker and more substantial, but in metal cladding systems, this can come at a cost.

Installation fit and weatherproof sealing becomes harder to achieve, but innovative reinforcement methods are now available delivering high impact and tear resistance in lighter, thinner sheet formats.

Finally, we come to the question of which kind of illumination is best for the building. High levels of light streaming through small openings in the roof - no matter how well diffused - inevitably deliver a mixture of glare and gloom. This is further worsened by increased shadows created within the

16

Nov/Dec 2017

building by both the fixtures & fittings, and the occupants. Achieving a good ‘average’ level of daylighting within a building is very different to delivering good uniformly distributed daylight.

This avoids the need for additional and localised supplementary artificial lighting. Glare and gloom can be significantly reduced by higher levels of diffusion from the rooflight. GRP, by its very nature, spreads daylight omni-directionally within the building and can make a major contribution to internal illumination uniformity and comfort levels. But responsible specifiers must always recognise that diffusion alone cannot deliver the uniformity of lighting that is so often assumed or taken for granted.

There are great savings and positive contributions to be made by incorporating rooflights into a building envelope. With every specification element, it is important to understand the need to strike a meaningful balance between the performance options of the rooflight. This way, the completed building will perform exactly as the specifier or client intended, and will show the building in the right light. www.hambleside-danelaw.co.uk/ zenon-rooflights

Creating Lighter, Healthier Warehouses For years, the typical image of a warehouse was a draughty, poorly-lit building.

Fortunately, times have changed. Developers and occupiers of modern warehouses and distribution centres now demand buildings which are designed to meet the highest standards in energy efficiency and wellness. To reach these objectives in the often-large internal spaces, specifiers require daylighting solutions that can distribute high quality light throughout the day whilst limiting glare and solar gains.

Switching on to Free Energy The fundamental purpose of any daylighting product is to harness sunlight within a building. Making the most of this ‘free’ source of light, however, requires careful pre-planning and analysis. Kingspan Light + Air carry out detailed assessments on each project, using daylight and thermal modelling, and local climate data to understand the building’s particular needs. This allows an optimal lighting solution to be created, combining premium daylighting products and low energy lighting with daylight harvesting and occupancy sensors — limiting all unnecessary artificial lighting, with the aim of keeping the lights off for the majority of daylight hours.

Switching off for Longer One of the traditional limitations with in-plane, roof-mounted daylighting systems is that they perform poorly when the sun is at low angles, such as early morning or late evening.

Kingspan Day-Lite Kapture rooflights have been expertly designed to address this issue. The product is installed out of plane on an upstand and features a contoured design comprised from three overlapping spherical domes. This unique shape allows light to be efficiently captured even at low sun angles – naturally

lighting buildings for the greatest possible number of hours in the day.

Switching to Quality Solutions Kingspan Day-Lite Kapture rooflights also feature a nano-prismatic composition, using microscopic structures to efficiently scatter light.

This innovative design helps to avoid the loss of light transmission associated with conventional pigmented diffusion approaches, ensuring excellent levels of light transmission with optimum diffusion, avoiding glare.

Kingspan Light + Air can adapt and tailor its products to each project’s unique requirements.

Kingspan Light + Air can adapt and tailor its products to each project’s unique requirements. In the case of Kingspan Day-Lite Kapture rooflights, options include an enhanced outer UV resistant layer to include IR blocking particles, providing additional protection for properties at risk of significant solar gains, and dual nanoprismatic layers for even greater diffusion.

Not Just for New As well as creating modern, well-lit warehousing, we must find solutions for that legacy of dark and draughty buildings that are still very much in use across the UK. Introducing natural light not only saves on energy bills,

FACTORIES & WAREHOUSES – advertorial it also improves productivity and the health and wellbeing of staff, bringing both direct and indirect returns on the investment for years to come.

Upgrading existing lighting systems to energy efficient LED further enhances the savings made, and helps to make even the most problematical buildings fit for purpose. Such measures may also be eligible for government incentives, and help to meet the requirements of the Minimum Energy Efficiency Standard that commercial landlords will have to comply with from April 2018.

Case Study Two outdated warehouses in Stocktonon-Tees were transformed into bright, modern workplaces with a specification combining Kingspan Day-Lite Kapture rooflights and Kingspan Smart-Lite Kite lighting – delivering projected lighting cost savings of over £13,000 per annum.

The warehouses, situated on the Teesside Industrial Estate, are currently leased by a flat pack furniture company. The main warehouse featured no rooflights and both buildings were lit with dim, high pressure sodium lights, making it difficult for staff to read labels. To resolve the situation, Hambleton Group Ltd contacted Kingspan Light + Air to develop an energy efficient lighting solution.

Kingspan Light + Air ’s expert technical team carried out a detailed daylighting analysis of the existing buildings - using 3D models and radiance simulation software to assess illuminance within the warehouses throughout the year. Based on this analysis, Kingspan specified and supplied 134 Kingspan Smart-Lite Kite modules along with 13 Kingspan DayLite Kapture rooflights.

Nov/Dec 2017

Installers, Mara Electrical, fitted the new lighting system over a period of three weeks with a carefully co-ordinated program designed to allow the warehouses to remain fully operational with minimal disruption. The modular design of the lights allowed them to be configured to each warehouses’ exact requirements whilst their high quality LED’s ensured excellent durability. To further reduce energy consumption, occupancy and daylight harvesting controls were also installed.

Kingspan Day-Lite Kapture rooflights were fitted above the main thoroughfare for lift-trucks. The rooflights are 100% UV resistant, can achieve a light transmission of up to 83% and meet non-fragility requirement ACR[M]001:2014 Class A. Simon Rees from installers - Roofing & Cladding Services - discussed the fit-out:

As well as creating a light, pleasant working environment, the systems are expected to reduce the warehouses’ energy usage by 80%. This should allow them to deliver full pay back in just over three years and deliver a return on investment of over 210% on the cost of the system within 10 years.

“By working in collaboration with Kingspan Light + Air, we were able to find a very cost-effective method of fitting the rooflights into the existing metal roof, by staggering the rooflights along the ridge line. This allowed us to simply weather seal the rooflights back to the ridge.”

FACTORIES & WAREHOUSES

Building envelope considerations for safer, more energy efficient and more productive factories Workplace (Health, Safety and Welfare) Regulations state that: “every workplace shall have suitable and sufficient lighting which shall, so far as is reasonably practicable, be by natural light”. Natural light provides optimal working conditions, as well as saving energy and cutting emissions by reducing the need for electric lighting. Smoke and comfort ventilation are also a critical factor in the success of industrial buildings, with the need for provision of a safe and comfortable working environment. David Mowatt, Director at Lareine Engineering and Chairman of the Smoke Control Association, explains the basics.

Daylighting Much has been written about the merits of diffused daylight in factories and workplaces – and the benefits are clear in terms of reduced requirements for electric lighting and improved working conditions.

Key considerations for daylighting in factories, are the the amount and type of light required. CIBSE Guide A recommends that for general manufacturing areas, the appropriate level of illumination is 500 lux and where accurate colour judgement or perception of movement are required, the recommended level is 1000 Lux.

when electric lights are switched off, so to achieve the optimum savings, an automatic lighting control system actuated by light sensors should be employed - so lights are only switched on when light levels drop below the desired level.

Smoke & natural ventilation

Every factory or manufacturing environment is different and specific needs will always need to be addressed, but these basic rules of thumb provide a starting point for designers.

Busy factories and warehouses may be noisy and will often contain high levels of combustible materials and stored goods. This places high emphasis on smoke control systems to ensure that in the event of a fire, a clear layer of smoke is maintained to aid escape from the building and allow fire brigade intervention. A properly designed smoke control system can also help protect the building by releasing the hot smoke out of the building. This action will also minimise smoke damage to stored goods and machinery.

It should also be noted that rooflights can never provide all the illumination required, so it’s important to consider how they will form part of an integrated strategy. Rooflights only save energy

System designs must always place the needs and safety of workers first, whilst also aiming to protect the fabric of the building to minimise production downtime or losses in the event of

CURTAIN WALLING

Opening the way for Kalwall® Structura UK has formed a strategic partnership with RAICO Bautechnik GmbH to develop an adaption of their THERM+ curtain walling system to accommodate Kalwall®, considered to be one of the most insulating light transmitting panel systems available.

The THERM+ framing system offers a wealth of possibilities such as the facility to conceal fixings and screws making for a seamless finish and the flexibility to use a frame in aluminium, timber or steel. It also presents the opportunity for semi-unitising the panels which can incorporate windows, Kalwall or a combination of both. This allows for monolithic, single action installations which save time on site and give excellent cost benefits together with a high performance long life cycle.

This new system variation is the result of intensive research and development at RAICO’s in-house testing facility in Pfaffenhausen, Bavaria. It has passed a series of assessments designed to replicate various CWCT (Centre for Window and Cladding Technology) criteria and EN 13830 “Curtain walling - Product standard”. Testing was completed using the RAICO THERM+ 56 A-I system with a standard Kalwall 70mm panel.

It is anticipated that one of the first installations to use this solution could be the Japanese Moshimo Skylight Restaurant in Brighton. Here, Structura and RAICO are working closely with architects studioSPOON, structural

engineers Atelier One, Brighton Council and English Heritage to try to realise this cantilevered restaurant extension suspended several storeys high over Bartholomew Square. The new system makes this daring and innovative project viable and will make use of the versatile stick frame by using steel, aluminium and timber backed curtain wall.

Steve Rogers, Sales Manager at RAICO UK comments, “Between ourselves, Structura and Kalwall we have modified our frames to create a fantastic system offering huge versatility and scope.

We’re delighted the initial rounds of in-house testing have proved so successful and are already looking at using this system on a raft of new projects both in the UK, across Europe and in the USA.”

It is anticipated that one of the first installations to use this solution could be the Japanese Moshimo Skylight Restaurant in Brighton.

DAYLIGHTING & ENERGY SAVING

Integrating daylight & artificial light to save energy Considerable savings in energy usage can be achieved by bringing daylight into a building through rooflights and windows and coupling this natural light with automatic controls that dim, or switch off, the lights during the day. Paul Bennett draws on research jointly commissioned by NARM, the National Association of Rooflight Manufacturers and LIF, the Livghting Industry Federation, to shed light on the potential savings that can be made.

Considerable savings in energy usage can be achieved by bringing daylight into a building through rooflights and windows and coupling this natural light with automatic controls that dim, or switch off, the lights during the day.

DAYLIGHTING & ENERGY SAVING minimising the area of rooflights would seem logical, as by its very design a rooflight will never have the same insulation values as the rest of the opaque insulated roof.

However, if the interaction of fabric and services is considered, then it is clear that the area of rooflights should be maximised in conjunction with the use of automatic lighting control systems. This will reduce the total energy requirements by avoiding or minimising the need for electric lighting throughout the working day. The small effect of the rooflight on the overall insulation value will be more than compensated for by the reduced use of electric lighting.

Energy saving with rooflights Research has proved conclusively that rooflights can save energy in many applications. A well designed, properly oriented building, with a good spread of natural light, will benefit from passive solar gain and a reduced requirement for artificial light. The combination of these factors means that including rooflights can offer a dramatic reduction in a building’s total energy consumption and the associated emissions of CO2.

A naturally lit interior will save money, provide a more pleasant environment that people want to spend time in, and contribute to the government’s target to reduce emissions of CO2.

Key points to note • As the rooflight area is increased from nil to 15% rooflights, there is a dramatic reduction in CO2 emissions • The energy saving is generally optimum at around 20% rooflights • When no rooflights are in place, the CO2 emissions from artificial lighting are generally significantly higher (3 times) than those due to the heating system

www.daylightingmag.co.uk

• The required energy for heating increases marginally as the rooflight area increases due to the additional heat loss through the rooflight compared to the opaque insulated roof but this is more than compensated for by the reduced use of electric lighting.

Automatic Lighting Controls Lighting controls have been specified and used in a wide range of buildings over the last 30 years and are recognised as a widely accepted technology. The objective of any lighting control system is to ensure that no light is ON when it is not needed, whilst giving users an easily understood access to the lighting at all times.

Lighting control options include: Dimming Dimming is easily the most effective way of managing artificial light in response to the availability of daylight. As soon as there is a daylight contribution the electricity use can be reduced as the artificial lighting smoothly dims. Dimming, when done effectively, is barely noticed by the occupants and it always ensures that the minimum required lighting level is achieved. In contrast, if the lighting equipment is not compatible with dimming, then daylight linked switching can be used but the switch OFF can only occur when the daylight contribution exceeds the required lighting level by a factor of three (or more). Great care also needs to be taken when setting the switch ON and OFF levels to ensure the lighting does not ‘hunt’. Dimming is also a valuable function when combined with occupancy and manual controls.

Maximising rooflight area in conjunction with the use of automatic control of artificial lighting will reduce the total energy requirements by avoiding or minimising the need for electric lighting throughout the working day.

The small effect of the rooflight on the overall insulation value will be more than compensated for by the reduced use of electric lighting.

GLAZED FACADES

Addressing fire risk in tall buildings with glazed facades Wrightstyle is one of Europe’s leading suppliers of advanced steel and aluminium glazing systems, supplying fire and blast resistant systems worldwide. Post-Grenfell, Tim Kempster, Wrighstyle’s managing director, looks at fire safety in tall buildings.

The Grenfell Tower disaster will cast a long shadow for many years to come, helping to define official attitudes to social housing and the imperative of fire safety in tall buildings.

While it’s too early to point fingers, it seems apparent that UK authorities have been complacent in believing that current regulations were fit for purpose and that, once again, it will be a case of

36

Nov/Dec 2017

“codifying by catastrophe.”

But it’s worth remembering that, while official enquiries grind forward, the building industry is still building upwards – and that fire safety in tall buildings is in a spotlight like never before.

Most of the UK’s tall buildings are in London, with others in Manchester,

www.daylightingmag.co.uk

GLAZED FACADES Birmingham, Leeds, Liverpool, Sheffield, Swansea and Brighton.

In London, there are 450 tall buildings in the pipeline. Of those, over 90 are being constructed, and the pace of upward development in the capital is accelerating, with 28 tall building completions this year, and 40 more in 2018. Brexit, it would appear, has yet had little dampening effect.

Those figures come from the London Tall Buildings Survey, which charts the number of towers of 20 storeys or more completed, proposed or currently in planning across the capital’s 33 boroughs.

The tallest residential building both in London and Europe will be the 67-storey Spire London at 235 metres high, near Canary Wharf, and scheduled for completion in 2020.

Or Chelsea Waterfront which will have two glass residential towers of 37 and 25 storeys, and Keybridge, the UK’s tallest residential brick tower, at 37 storeys, and 1 Undershaft, which will be the second-tallest building in western Europe – and the tallest building in the City of London.

The Shard remains the tallest building in both the UK and Europe, topping out at 310 metres with 87 storeys. It has 11,000 panes of glass and a total surface area of 56,000 square metres, and is partly residential.

Its early designs were influenced by a report from the US National Institute of Standards and Technology (NIST) into the collapse of the Twin Towers in September 2001, which were just over 400 metres tall, which found that “the towers withstood the impacts and would have remained standing were it not for the dislodged insulation (fireproofing) and the subsequent multifloor fires.”

While the Shard is the tallest building

www.daylightingmag.co.uk

in Europe, it will be dwarfed by the tallest of them all, the Kingdom Tower in Jeddah, Saudi Arabia – the first habitable building to pass the one kilometre mark, and due for completion in 2019.

The £780 million Kingdom Tower will stand at just over 1,000 metres, have 200 storeys, and require some 500,000 cubic metres of concrete and 80,000 tons of steel. It will also be partly residential.

It will be three times higher than the Shard and 173 metres taller than Dubai’s Burj Khalifa, currently the world’s tallest building at over 828 metres – with 160 storeys.

The challenges will be immense, not least how to pump wet cement half a mile upwards. To erect the Burj Khalifa, cement pumping took place at night to reduce heat.

In London, there are 450 tall buildings in the pipeline. Of those, over 90 are being constructed, and the pace of upward development in the capital is accelerating, with 28 tall building completions this year, and 40 more in 2018.

But it’s China that is setting the pace, with a number of ultra high-rise developments, including the Shanghai Tower which, at 632 metres, is China’s tallest building – and the second tallest in the world.

The new 541 metre One World Trade Center, the building that replaced the Twin Towers, is the only US skyscraper in the Top 10 tallest buildings in the world at 541 metres – but not for long as other countries build further into the sky.

Third in the super-tall list is the Makkah Royal Clock Tower Hotel, in Mecca, Saudi Arabia. Besides hotel rooms, the tower has a conference centre, an Islamic Museum and prayer room for up to 10,000 people, a Lunar Observation Centre for watching the moon during the Holy Month, and a shopping mall with five storeys.

In London, with high land prices, the logic of building upwards is inescapable, and creating high-rise

residential blocks will help to alleviate the city’s chronic housing shortage – if design lessons from the past can be learned.

Glasgow’s Red Road flats are a case in point. Built in the early 1960s, and Europe’s highest residential blocks when they were built, the steel-framed buildings were fire-proofed with asbestos, which blighted the flats for years.

But the biggest lesson for architects, building designers and fire safety experts must be to take heed of Grenfell Tower and to never again lapse into false security. That’s the real lesson from that disaster – that complacency is the enemy of fire safety.

Wrightstyle has worked on fire safety on a number of high-rise developments

38

Nov/Dec 2017

in the UK and internationally. The company has also raised concerns about fire regulations in both the UK and UAE, and changed its certification processes, so that a fire certification on one of our glazing systems could not be unilaterally applied on another project.

In the new generation of superbuildings, fire safety takes on a whole new dimension, because – beyond sprinkler systems – how do you tackle a fire a kilometre up in the sky?

The answer is: with great difficulty, and there have been several notable cases where a sprinkler system has made things worse, with cold water coming into contact with non-fire rated glass and causing the glass to break and allowing more oxygen to reach the seat of the fire. The same is true

www.daylightingmag.co.uk

GLAZED FACADES of tempered glass, with a limited firerating.

The most effective way of dealing with fire at high altitude is by fire compartmentation: keeping the fire contained in one protected area and preventing it from spreading. A contained fire can be dealt with; an uncontrolled fire can’t.

A rule of thumb for fire safety in supertall buildings is that any fire should be able to burn itself out, without external intervention, and without building collapse. That allows for a limited evacuation of people on the affected floor and on floors immediately above and below the fire.

nearly 550 storeys, with enough room for 100,000 people. It was fanciful then, but not so fanciful now. It’s probably only a matter of time before human imagination and construction technology make it possible.

Over the years, we’ve seen the good, bad and the ugly of fire safety design, and hope that the new cities in the sky pay heed to the absolute need for a whole new level of fire safety and, if the worst does happen, have fire containment strategies to ensure everyone’s safety.

There have been several notable cases where a sprinkler system has made things worse, with cold water coming into contact with non-fire rated glass and causing the glass to break.

After Grenfell, that’s the least that we in the UK can do. www.wrightstyle.co.uk
