EDITOR’S COMMENT

Here comes summer! ...and summer’s challenges.

As we head into the summer, most of us welcome the pleasing increases in temperature and daylight levels, even despite concerns about climate change.

explores the topic in relation to warehouses and industrial buildings.

At this time of year, greater emphasis is placed on the need for careful consideration of how daylight is managed in internal spaces, to avoid unwanted heat build-up or glare.

As a case in point, a friend of mine has recently had a large rooflight installed over a new flat roofed extension. The result is a beautifully daylit space beneath. But there is a downside. Even at this early stage in the year, he has noticed that on bright afternoons, the temperature inside is becoming a cause for concern.

This issue carries a timely feature which looks at the subject from two very different perspectives. Nigel Hill’s article on page 16 explains how dynamic shading can play a role in managing daylight in commercial, residential and public spaces, whilst our case study on page 20,

Both articles highlight the need for careful consideration and choice of materials and systems at the specification stage – and this fact is further reinforced by Jeremy Dunn’s revealing article on flat glass rooflights on page 22.

This article is indicative of the fact that there is a huge amount of expertise in our industry, that’s widely available to buyers and specifiers. And yet, the incidences of errors or malpractice resulting in functional problems or even safety concerns, appear to be increasing.

Paul Bennett paul@daylightingmag.co.uk

The reason would appear to be simple: too many buying decisions in which cost has been the predominant factor. With so many new suppliers coming into the UK construction products marketplace in recent years, competition has increased – which is arguably a good thing. But not when the balance between cost and quality tips the wrong way.

UK Green Building Council presents industry framework for net zero carbon buildings ten years will see the scope and ambition of the framework increased to encourage greater action. In the short-term, additional requirements will be introduced to challenge the industry, including minimum energy efficiency targets and limits on the use of offsets. In the longer term, the two approaches for construction and operational energy will be integrated into a broader approach for net zero whole life carbon, covering all of the emissions associated with the construction, operation, maintenance and demolition of a building.

The UK Green Building Council (UKGBC) has today unveiled a framework for the UK construction and property industry to transition new and existing buildings to become net zero carbon by 2050, in line with the ambitions of the Paris Climate Agreement.

and occupiers targeting net zero carbon buildings, setting out key principles to follow and outlining how such a claim should be measured and evidenced. Two approaches to net zero carbon are proposed by the framework which can be accurately measured today:

The report follows six months of intense industry engagement, involving over 180 experts and stakeholders from across the built environment value chain, and is supported by 13 trade associations and industry bodies including BPF, RICS and RIBA. It provides an overarching framework of consistent principles and metrics that can be integrated into tools, policies and practices, and aims to build consensus in the industry on the approach to decarbonising buildings.

– Net zero carbon – construction: the embodied emissions associated with products and construction should be measured, reduced and offset to achieve net zero carbon.

The new framework offers guidance for developers, owners

The work has been made possible thanks to the generous support of lead partner Redevco Foundation, and partners BAM, Berkeley Group, Grosvenor, JLL and Hoare Lea. Richard Twinn, Senior Policy Advisor at UKGBC said: “The urgency of tackling climate change means that businesses must work together to drive down emissions as fast as possible.

But this requires a shared vision for what needs to be achieved and the action that needs to be taken. This framework is intended as a catalyst for the construction and property industry to build consensus on the transition to net zero carbon buildings and start to work towards consistent and ambitious outcomes. It is the first step on a journey towards ensuring all of our buildings are fit for the future.” www.ukgbc.org

Construction Products Association reports signs of Weakness in UK Construction in Q1 The construction industry experienced a mixed quarter for products sales, output and new orders in the opening three months of 2019, according to a quarterly survey of the supply chain’s product manufacturers, contractors, civil engineers and SME builders by the Construction Products Association.

The Construction Products Association’s Construction Trade Survey for 2019 Q1 shows that during the quarter, sales of construction products rose according to 54% of heavy side manufacturers and 29% of light side manufacturers. In contrast, 20% of main contractors reported a decrease in output during the quarter, whilst workloads were reported lower for 17% of civil engineering contractors and 7% of SME builders. Only product manufacturers and SME builders reported positive readings in forward-looking indicators, with a broad-based fall

www.daylightingmag.co.uk

in new orders reported by main contractors and civil engineers.

Commenting on the survey, Rebecca Larkin, Senior Economist at the CPA, said: “The year opened with a mixed quarter of performance for construction.

Confidence among consumers and businesses remains low and this has reduced the amount of work coming through to the two largest construction sectors, private housing and commercial, which require greater visibility over the economy’s future growth path to see projects get the go-ahead. By itself this raises concern over the extent to which the political stalemate over Brexit is affecting UK construction, but the risks are intensified when combined with the prevailing narrative of rising costs for labour, raw materials and fuel eroding contractors’ margins.”

Richard Beresford, Chief Executive of the National Federation of

Builders, said: “Member reporting indicates bad news for the sector as material costs keep increasing while contractors’ order books continue to decrease. While companies can take steps to prepare their business for exit from the EU, the pace of progress by the Government continues to affect confidence and highlights the need for greater certainty.

Commenting, Director of External Affairs for the Civil Engineering Contractors Association (CECA), Marie-Claude Hemming, said: “We are concerned that the industry is experiencing a decline in output at a time when the Government should be taking steps to shore up the economy.

A decline in growth will have ramifications for businesses and communities who rely on our members to deliver the worldclass infrastructure the UK needs.” www.constructionproducts. org.uk

Construction for the logistics sector gathers pace Recent major project announcements and an upbeat trading statement from the UK’s largest industrial developer suggests construction activity in the logistics sector has gathered pace in the opening months of this year.

Manufacturers are understandably nervous about Brexit but if anything, the recent stockpiling by firms has highlighted the need for more high-quality logistics space. Glenigan Construction market analysis shows that the value of warehousing and logistics projects starting on site in the first quarter was up 22% on the period a year earlier.

Meanwhile a recent report from JLL, the UK Big Box and Logistics market, said appetite in the investment market for logistics space remains strong and is forecast to continue to outperform the retail and office

sectors over the next five years.

It points to the growth of online sales as a driver of demand for logistics space this year and predicts a further rise in the supply of Grade A ‘big box’ units.

Segro - the industrial space developer which is now Britain’s largest property group by stock market value - recently painted a promising picture of its core market as it benefits from the growth of e-commerce and growing urbanisation.

In the first quarter alone, Segro completed 100,000 sq m of new industrial space and it currently has 44 projects under construction. In all, the group now has some 1 million sq m of space either under development or with approval.

Having recently raised £451 million in new equity, this year the group expects to invest a total

of £400 million on development capital expenditure and a further £200 million on land acquisitions.

One of the group’s key projects where work has recently started is the £11 million Vantage Logistics Centre at Segro Park Heathrow, where McLaughlin & Harvey is the main contractor (Glenigan Project ID: 17241505).

Investment plans at the major industrial/logistics groups also suggest the construction pipeline in the sector will remain healthy. For example, in Warrington in the North West, Eddie Stobart Logistics has submitted detailed plans for a new £73 million distribution centre building where work is set to start at the end of this year and continue for 20 months. www.glenigan.com/ logistics-construction/

Four new EPDs for Vetrotech Saint-Gobain As part of its ongoing efforts to maintain the status of an important partner for sustainable construction projects, Vetrotech Saint-Gobain has extended its Environmental Product Declaration (EPD) by four additional declarations.

The four new EPDs have been published to make the environmental impact of Contraflam 60, 90 and 120 more transparent. The EPD for Contraflam 30 fire-resistant glass now specifically includes the oversize MEGA which has

8

May/Jun 2019

the largest tested sizes on the market at 2600mm x 4600mm.

EPD’s have been created to meet the demand of architects, designers and specifiers for consistent and transparent information about the impact of the materials they use on the environment.

They are an essential tool for planners and architects involved in projects aimed at achieving Green Building certifications such as LEED and BREEAM. Rob Wood, General Manager

of Saint-Gobain UK & Ireland commented “Vetrotech’s commitment to securing EPD’s showcases how serious we are about sustainability. We believe in being transparent with where our product comes from, how it is made and delivered.

EPD’s are much more than an accreditation, they hold companies accountable for their impact on the environment”.

The EPD itself is valid until 2023 and can be viewed on the website of the international EPD system at environdec.com.

80% of consumers say that the design of homes impacts their wellbeing factors including improved health, happiness, productivity and better mental well-being, with research also suggesting it can help reduce the effects of seasonal affective disorder.

New research published

by Eurocell plc, the UK manufacturer, distributor and recycler of PVC-U window, door, conservatory and roofline systems, has revealed that four in five consumers believe the design of their home impacts their wellbeing, demonstrating the growing demand for homes designed to promote good health.

When asked about wellbeing in the home, 83% of female respondents and 73% of males said that feeling comfortable and secure in their home impacted their overall wellbeing.

When asked what top three factors contribute to consumers feeling good in their own home respondents identified the amount of natural light (48%), low noise levels (39%) and feeling safe and secure (37%). These were closely followed by access to outdoor space (36%) and the design and layout (35%).

One of the key drivers behind this trend is growing consumer awareness of the impact of the built environment on personal well-being. The benefits of homes with high levels of natural light are well established and include positive impacts on

Chris Coxon, Group Head of Marketing at Eurocell, commented: “For today’s home occupier, incorporating wellbeing into the design of the home is increasingly important. The trend stems from the public being far better educated about the importance of wellbeing and what can be done to improve it, such as increased exposure to natural light. This awareness is influencing all types of design, leading architects, builders and developers to seek innovative approaches to wellbeing features within home.”

The research is part of Eurocell’s ‘The Future Home Report’, and draws on the views of 1,000 25-40-year olds that either own or rent homes, about design and build considerations for future homes.

Construction industry suppliers ‘are prepared for Brexit’ As part of a larger survey which included merchants and other construction industry stakeholders, MRA Research, the specialist research division of MRA Marketing, asked building and home improvement product suppliers what they thought the impact of Brexit would be on the UK, the building industry and the company they worked for.

Like voters and MPs, industry suppliers are split in their expectations for Brexit. Almost half of the suppliers interviewed (49%) think Brexit will be either bad or very bad for the UK as a country, while 27% think the effect on the UK will be good

or very good. Nearly one in five (18%) think it will have no impact. Many respondents commented separately that, although there may be a slight dip in the short term as a result of leaving, they thought there would be less of a negative impact in the longer term.

Interestingly, suppliers felt less strongly about the potential impact on their own company than they did about the effect on the UK. Eighteen percent expect the company they work for to be better off as a result of Brexit, compared to 27% expecting the same for the country.

Reviewing the potential impact on the building industry, 18% of suppliers surveyed said Brexit would be good or very good for the building industry, compared to 45% who thought it would be bad or very bad. Twenty eight percent thought it wouldn’t make much difference either way.

Respondents were also asked about changes they expected to see as a result of Brexit in sales, prices, stock levels and other issues in the next 12 months.

CONTROLLING HEAT & GLARE

Daylight is good.

Sunlight is bad.

Nigel Hill, Managing Director at Umbra Shading, explains the benefits of Dynamic Shading Systems in the management of daylight in buildings.

When it comes to health and wellbeing, we are constantly bombarded with conflicting messages. Whether it’s protein, statins or red wine, they are alternately the hero or the villain of various scientific studies.

Sunlight suffers the same fate. We are encouraged to get exposure to the sun for vitamin D and for healthy circadian rhythms; but we must also cover up due to skin cancer risks. Likewise for buildings. We harvest the free energy for daylighting, and to generate

16

May/Jun 2019

electricity and heat via solar panels; but we grapple with overheating and with glare from the same source.

So how do we manage this dichotomy? How can we maximise the good whilst minimising the bad?

Firstly we must acknowledge that this is a dynamic challenge. The sun tracks across the sky from sunrise to sunset, and its track is different for every day of the year. At least this is fully predictable variance. The weather is another big

www.daylightingmag.co.uk

CONTROLLING HEAT & GLARE variable, predictable only in the short term. A third set of variables is with the building itself: latitude, orientation and usage of spaces all play a part.

All these factors combine to produce enormous variations in the levels of natural light experienced by building occupants. Buildings designed to maximise daylight will likely have glare and overheating issues; those designed to block glare will end up being deprived of daylight on dull days and make excessive use of artificial lighting.

Clearly no static solution is capable of providing a satisfactory outcome. At best, it will only be effective for some of the time. At other times it will be detrimental to the experience and wellbeing of building occupants. It will also increase the building’s energy consumption, for cooling or for artificial lighting.

A dynamic challenge needs a dynamic solution.

Dynamic shading is required to make the most of the sun’s free energy whilst managing the adverse effects.

A dynamic shading solution allows us to confidently design for daylight

CONTROLLING HEAT & GLARE

Not just for modern buildings, dynamic shading can be retro-fitted

harvesting, knowing that glare and overheating can be managed in very bright conditions, but without compromising the daylighting in less bright conditions.

So what constitutes dynamic shading?

At the most basic level, any form of shading that can be adjusted depending on the conditions could be called dynamic, as opposed to static.

However, a truly dynamic system is one which can respond autonomously to the conditions.

We have long taken it for granted that thermostats automatically regulate heating and cooling systems. Artificial lighting is frequently controlled by occupancy and/or lux level sensors.

Yet window blinds are generally left to be controlled manually, relying on human presence and inclination to maintain optimum conditions. This often leads to the original design

18

May/Jun 2019

intentions and calculations for daylighting, overheating and energy consumption being compromised.

A successful dynamic shading system consists of two key components: the shading material and the method of control. If either of these should be prioritised it is the controls, because the very best shading material will not do its job well if not deployed intelligently. It is essential that this is considered as early as possible in the project design phase, so that the optimum solution is designed in from the start.

Automated dynamic sun shading systems, using the latest shading materials and intelligent control technology, are the way in which we can harness the benefits of daylight without the harmful effects of glare and overheating. Bring on the sunshine!

GRP rooflights create the ideal storage conditions for Lidl

Left: Before refurbishment, the existing polycarbonate rooflights delivered harsh, un-diffused light and localised high temperatures.

Right: Following installation of GRP rooflights, lighting is diffused and storage conditions are optimised, with no localised heat build-up

Over 3700m2 of Filon Monarch F GRP barrel vault rooflights have been installed at the Lidl Distribution Centre in Runcorn, Cheshire as part of a refurbishment program by Ascot Property Maintenance Ltd. The existing polycarbonate barrel vault rooflights had started to fail, resulting in water ingress in some areas of the building. A further long-term problem with the existing rooflights was direct, un-diffused light which was causing glare and localised heat build-up: both unwelcome characteristics in a food storage warehouse environment.

Darren Fletcher of Ascot Property Maintenance takes up the story: “We were aware of the light diffusing capabilities of Filon GRP rooflights, so we contacted Filon Products to help us demonstrate this to Lidl’s Facilities Management team.”

Filon’s technical team responded with samples and recommended the company’s Monarch F GRP barrel vault rooflights as the ideal replacement solution due to their excellent light diffusing properties and suitability for use on curved metal profiled roofs.

20

May/Jun 2019

In addition to meeting Lidl’s needs for improved light diffusion, Filon rooflights offer high strength, allowing the installation to achieve the required Class B non-fragility rating.

High energy efficiency was another key factor in the rooflight specification and in this respect, Filon was also able to meet the challenges posed by the Lidl project.

Darren Fletcher continued: “In order to meet the required U-value for this building to achieve compliance with Part L2 of the Building Regulations, the Monarch F system was modified to incorporate an additional multiwall polycarbonate glazing sheet between the GRP inner and outer skins.”

The new rooflights now provide the required high level of evenly distributed natural daylight – with no unwanted glare, reduced internal temperatures and no ‘hot spots’. This creates improved storage conditions and makes life easier, safer and more comfortable for staff. www.filon.co.uk

Low pitch or curved roof?

Think Monarch F rooflights.

Filon Monarch F factory-assembled GRP barrel vault rooflights provide the perfect solution for delivering high levels of diffused natural daylight to metal shed type buildings like factories, warehouses and large retail stores These tough and durable rooflights are fabricated from high quality Filon GRP sheets which are robust, shatter resistant and unaffected by extremes of temperature. Long-term surface protection is provided by a UV absorbing film that is applied to the weather surface during manufacture.

ROOFLIGHTS

Five reasons to avoid ‘under-spec’ rooflights and what to look out for when specifying.

NARM, the National Association of Rooflight Manufacturers, has recently received a number of complaints relating to glass rooflights which have either been sourced from a disreputable manufacturer, or fabricated by a non-specialist builder. NARM Product Standards Representative Jeremy Dunn highlights a number of concerns regarding these.

Over recent years, there’s been a huge surge in popularity for modular flat glass rooflights, which are widely specified for domestic and commercial projects – and with good reason. There’s a large range of excellent, very high quality examples available from reputable suppliers, all of which offer superb aesthetics and very high performance with excellent U-values.

However, NARM has recently received a number of complaints regarding product performance from individuals who have installed or commissioned what they believed to be high quality products, only to be disappointed.

More importantly, a number of these instances have also revealed major safety concerns.

As the trade association representing bona fide high quality UK rooflight manufacturers, we’re concerned that this minority of ‘rogue’ manufacturers are giving our industry a bad name and we’d like to set the record straight. So, here are the reasons why you should reject under-spec rooflights and how you can avoid being ‘sold a dud’.

1. Safety of building occupants To ensure those below the rooflights are safe, the first choice for the inner pane of a rooflight should be a

22

May/Jun 2019

laminated glass, as this minimises the risk of any glass falling into the room beneath and consequent injury, if the inner pane should break.

Toughened glass inner panes bring a risk of shattering and falling into

www.daylightingmag.co.uk

ROOFLIGHTS the room beneath (occasionally spontaneously, but certainly if impacted). NARM is aware of some manufacturers taking advantage of the fact that the term ‘toughened’ implies safety. In this instance, it does not.

British Standards define that inner panes must always be laminated wherever rooflights are more than 5 metres above floor level (increased to 13 metres in limited circumstances) or are located over water (eg swimming pools). The British Standard may permit use of toughened inner panes in other applications but only if a stringent risk assessment is carried out, confirming that its use does not give any additional risk to those below the rooflight. It is difficult to see how use of a toughened rather than laminated glass inner pane doesn’t present a risk to anyone beneath the rooflight, so you should always ensure that the inner pane is laminated glass.

Some more economical designs consist of nothing more than a double glazed unit stepped on all four sides with no perimeter frame, with the outer pane sealed to the top of an upstand and the inner pane hanging inside the upstand. Such designs are not preferred, having much greater reliance on quality of site installation, but if they are used it is essential that the installer provides a continuous support for the inner pane on all four sides, to avoid risk of the whole rooflight dropping into the building beneath if the outer pane should be broken. Should this be overlooked or the work carried out to a poor standard, there is a serious risk of injury to anybody below should the outer pane of glass break or the edge seal fail.

2. Safety for personnel accessing the roof In addition to using a laminated inner pane to protect building users, rooflights can also be specified and designed to be non-fragile*. This is intended to ensure that anyone accidentally walking or falling onto the rooflight will not fall through it, even if the glass is broken or the rooflight damaged. In this instance, a 9.5mm or 11.5mm laminated inner pane is usually necessary (depending on rooflight size) to comply with non-fragility requirements.

“...a number of cases where underspec rooflights are installed, have revealed major safety concerns.”

CDM Regulations require that a risk assessment should be carried out for every construction project, and this should define the measures required to prevent significant risk of anyone falling through a rooflight. Wherever there may be risk of anyone ever being on a roof near a rooflight that they could accidentally step or fall onto (eg for maintenance purposes), you should specify a non-fragile rooflight.

3. Watertightness and water run-off Another major cause for complaints has been leaking rooflights causing damage to roof structures and interior decorations. NARM has been contacted regarding instances where the glazing frame has been poorly designed, or the rooflight has been installed poorly and/or without sufficient pitch to allow water run-off, resulting in water building up on the glazing and eventually penetrating edge seals.

Most high quality glass rooflights incorporate a glass unit factory bonded into a fully thermally broken aluminium frame, which includes a drip detail to

* It is important to note that The term ‘non-fragile’ can be applied to a wide range of rooflight types offering varying degrees of durability and impact resistance. Glass, polycarbonate and GRP rooflights can all be supplied with non-fragile classifications. A non-fragile rooflight is NOT designed to be walked upon and the term should not be confused with rooflights which are specifically designed for foot traffic. These ‘walk-on’ rooflights are very high specification glass structures designed to floor loadings and installed in-plane with external floors on roof decks and roof terraces where pedestrian access is unrestricted.

ROOFLIGHTS

A wide variety of designs are available from high quality, specialist rooflight manufacturers. When buying glass rooflights, always ensure that the inner pane is laminated glass. A quick way to be sure of regulatory compliance and appropriate safety standards is simply to check that the rooflight has been supplied by a NARM member.

ensure the unit is fully watertight as soon as it is fitted onto an upstand.

They should be sealed to the upstand on site (for airtightness as well as watertightness), but the seal is only a secondary seal, rather than the primary means of preventing water ingress. In some more economic designs there is no frame, and the glass is simply sealed to the upstand on site. The absence of any drip detail on a frame means water can easily track back on the underside of the glass, and watertightness of the units becomes entirely dependant on the quality of the site applied seal (often onto an upstand which is not flat and level, after the upstand itself has been weathered), which can cause leaks: this style of rooflight should therefore be avoided.

Glass is not completely rigid and any glass rooflight will bow slightly under the effect of gravity. Flat glass rooflights should therefore always be installed at a slight pitch to avoid ponding (which would otherwise occur if the bow created a negative pitch).

Typically smaller rooflights should be installed at 3 degree pitch, and larger flat glass rooflights should be installed at 5 degree pitch. You should always make sure that the contractor who is building the upstand is aware of this pitch requirement, to avoid the unsightly problems associated with ponding (including rapid dirt build-up, and potentially water ingress).

24

May/Jun 2019

Some rooflights are offered with “selfcleaning” glass, which is misleading: true self-cleaning glass (such as Pilkington Activ) works best at pitches above 30 degrees, with a minimum pitch of 10 degrees so is not suitable for flat glass rooflights. Some grades of low maintenance or easy-clean glass can be used, but still require regular cleaning.

4. Security For domestic properties, Part Q Building Regulations state that rooflights deemed as easily accessible need to be proven to resist criminal attack or incorporate features that are proven to reduce crime. We’re aware of rooflights being supplied for domestic use with no mention of Part Q. Even rooflights supplied with a laminated inner pane may not pass Part Q testing as the outer could be broken and then the inner pane just lifted out of the hole.

“It’s important that manufacturers state ‘whole product’ U-values to ensure thermal performance which will allow compliance with Part L Building Regulations.”

5. Thermal performance It’s important that manufacturers state ‘whole product’ U-values to ensure thermal performance which will allow compliance with Part L Building Regulations. Some manufacturers are quoting ‘centre pane’ U-values which do not take into account edge spacers and frame construction. The thermal performance of a rooflight must be considered for the whole assembly, because while glazing may

www.daylightingmag.co.uk

ROOFLIGHTS be compliant, poor frame design can affect thermal performance. This can result in higher energy bills for building users and subsequent unwanted higher CO2 emissions.

Remember: a great-looking rooflight isn’t necessarily a great rooflight NARM has noted that in many cases where complaints have occurred, the manufacturer is targeting homeowners with sophisticated websites and literature focusing heavily on the aesthetics of the product and often claiming excellence in quality standards. Some have even referenced NARM documents on their marketing materials. Beware!

In a crowded marketplace, where some manufacturers are making confusing or untrue claims, careful consideration needs to be given to rooflight choice, if problems of water ingress, ponding or

worse still, inadequate safety, are to be avoided.

The good news is that there are many excellent, trustworthy UK suppliers of properly designed rooflights which will offer years of safe and reliable service.

One simple and certain way to ensure you’re dealing with such a company, is to establish whether your supplier is a NARM member company. NARM has stringent membership criteria, a key part of which is that any product supplied by a member company is fully compliant with Building Regulations and meets all required specification and safety standards.

DAYLIGHTING IN PUBLIC SPACES

Shining light on a local community Natural light shines bright throughout the new Kilternan Parish Community Centre in County Dublin, following refurbishment of the original parish hall and the development of a completely new building.

“What was developed was a naturally-lit, 770m2 contemporary centre that includes facilities such as a large multi-use hall, a café and hospitality area, kitchen and meeting rooms, along with an on-site car park.”

Kilternan Parish Church, which is in the Church of Ireland Diocese of Dublin, has been an essential pillar of the local community since 1826.

As well as offering a full range of worship services and faith formation opportunities, the church provides activities for children, young people and members of the community. In 2018, Reverend Rob Clements, Rector of Kilternan Parish and his parishioners, kick-started a project to extend these services, with the aim of becoming a resource for a broader range of activities for people of all ages.

To do this the church needed more space, which was proposed in the form of a multi-use community centre and would be open to the people of the parish, the wider community and a range of local groups and voluntary

26

May/Jun 2019

organisations. The construction of the centre comprised of two main elements: a refurbishment of the original parish hall and the development of a completely new building.

Architect Stephen Newell, who is also a parishioner of Kilternan Church, was appointed to create the design for the new development and refurbishment.

His brief was to design a modern building with a range of amenities and a welcoming aesthetic that would not look out of place in the church grounds.

What was developed was a naturallylit, 770m2 contemporary centre that includes facilities such as a large multiuse hall, a café and hospitality area, kitchen and meeting rooms, along with an on-site car park.

Challenge

Solution

During the design process, it was made clear that one of the most important requirements was for the centre to feel open and well-lit, with a preference that it is illuminated by natural light.

The client specifically stated that they wanted people to feel ‘lifted’ as they entered the building and its rooms.

The easiest solution to this challenge would have be to install artificial lights, however keeping the centre’s energy costs to a minimum was important, as was optimising the levels of natural light within the building. Therefore, it was felt that the most effective method was to use skylights.

This was achievable within most parts of the front of the building, through a glass façade that faces onto the church grounds and basks in sunlight, particularly during the summer months.

However, the rear of the building, which houses the community hall, was built into a hillside, meaning that there could be no windows in the exterior wall. This meant the architect was presented with the challenge of optimising the levels of natural light within these rooms, without the use of vertical windows.

Having been made aware of the benefits of VELUX modular skylights during a trade event, and after working with the VELUX core business, the architect approached the VELUX Commercial team.

28

May/Jun 2019

Designed in collaboration with Foster + Partners, VELUX modular skylights are the result of years of research.

The skylights are fully prefabricated off-site and can be installed up to three times faster than a traditional rooflight system. They also have sustainability credentials, with exceptional energy

www.daylightingmag.co.uk

DAYLIGHTING IN PUBLIC SPACES performance and a life expectancy of 30 years or more. Each roof glazing solution is delivered with a special prefabricated flashing ensuring a perfect fit and 100% water tightness.

These features, plus the fact they come with a ten-year warranty, meant that VELUX modular skylights were the ideal solution for this project. Following a meeting with the technical team, in which the architect learned more about the different rooflight configurations offered by VELUX, a decision was taken to progress with a ridgelight solution at a pitch of 25°.

Specification 28 x fixed units of 1000mm x 1000mm were installed by C&I Carpentry Ltd, a VELUX Commercial installation partner, in the main hall forming an atrium like design along the centre of the roof, and the bright, uplifting space that the client was seeking.

Another important consideration was minimising glare and controlling the temperature inside the hall, which acts as both a multi-use community space and sports halls for local teams and fitness clubs. As such, factory-fitted, integrated roller blinds were included in the specification. They can be automated and controlled remotely using the VELUX INTEGRA® system.

Vertical windows only usually provide illumination to around 6m into the room. So, to increase levels of natural light throughout the rear of the café, 6 x 1000mm x 1600mm wall mounted longlights at a pitch of 15 ° were installed in this area, two of which are venting units, and are again controllable via the VELUX INTEGRA® system. The comfort venting modules allow the hottest and stalest air to escape efficiently, reducing the need for energy-intensive air conditioning systems.

www.daylightingmag.co.uk

In total, the modular skylights took just two days to install, resulting in the client benefitting from a reduction in installation costs and as the roof was closed sooner, other internal works could progress quicker, and the development completed on time.

Reverend Rob Clements comments: “We are delighted with the development of the centre. The use of VELUX modular skylights has helped to create the light, harmonious feel we were seeking. Even during the days when it has been dark and cold outside, parishioners have commented on how bright and welcoming the centre is inside, especially the hall and cafe.”

Stephen Newell, of Stephen Newell Architects, comments: “Although this was the first time specifying VELUX modular skylights, I have worked with VELUX on numerous occasions, so I was confident that the quality of the product and the professionalism of the team would be high.”

Vertical windows only usually provide illumination to around 6m into the room. So, to increase levels of natural light throughout the rear of the café, 6 x 1000mm x 1600mm wall mounted longlights at a pitch of 15 ° were installed in this area

He adds: “The ridgelight provided a perfect solution to the challenge of incorporating natural light into what would have otherwise become a box-like space, lit solely by artificial lighting. As a member of the church I am frequently in and out of the building and have seen first-hand how the modular skylights within the hall and café have turned these areas into some of the most popular rooms within the centre.” https://commercial.velux.co.uk/en

MUSEUMS & GALLERIES

Daylight control expertise puts valuable pieces of art in the shade World-class galleries and museums need world-class solutions when it comes to protecting their valuable artworks from the harsh effects of daylight. Shading specialist Guthrie Douglas was called in to provide answers for two high-profile institutions.

When the architects behind The Broad Museum of Contemporary Arts, in Los Angeles, USA, and The Latvian Museum of Art in Riga, looked for ideas on controlling daylight in their exhibition spaces, they turned to the well-known shading specialist Guthrie Douglas.

The pioneer of the single-motor, single-barrel tensioned shading system

devised two different and innovative installations that enable light to filter through without damaging the artwork.

Andrew Kitching, Managing Director of Guthrie Douglas, said the projects called for more than just engineering prowess – they also required a scientific understanding relating to the preservation of artworks. “Calculation of solar radiation exposure

MUSEUMS & GALLERIES levels is an exact science, and must take into account many factors including the material composition and reflection of gallery surfaces, artwork lifespan, rate of exhibit change, and materials analysis of individual art pieces,” he says.

“Where direct light is transmitted through glazing, careful modelling must take into account the variations of aspect, location and season.”

This can be challenging; for permanent collections, typical limiting annual exposure can be as low as 15,000 lux hours at an illuminance of 50 lux for highly sensitive materials.

The Guthrie Douglas TESS™ 660 system was selected for the vaulted rooflights at The Broad Museum of Contemporary Arts, in Los Angeles, USA, because it was the ideal solution to balance the unusual lighting from the “veil and vault” design by architects Diller Scofidio + Renfro.

To control the light levels from 100% ambient light to 100% blackout, each of the 350 uniquely shaped rooflights was fitted with a Guthrie Douglas TESS™ 660 tensioned blackout shade and was connected to a single wireless network that covered the roof. This enables diffused light to filter through and the system also allows museum staff to open and close the shades quickly and easily.

beautiful views of the city, light levels have to be controlled and sometimes blocked out.

Working with Latvian lighting and fit out specialists Multisell Sistemas, Guthrie Douglas designed a dual system that features both a blackout and a translucent fabric, creating a multilayered lighting effect.

“Where direct light is transmitted through glazing, careful modelling must take into account the variations of aspect, location and season.”

Using the compact TESS™ 660 technology, dual fabric guides were installed onto the slim glazing mullions, which allows curators to choose four levels of filtered light, including blackout.

Motorised fabric barrels were integrated into the ceiling and flooring and both fabrics remaining perfectly flat, thanks to a torsion spring that is concealed in the barrel.

“These extraordinary exhibition areas each had their own technological challenges to overcome, but our engineers devised shading solutions that were not only innovative, they provide to be transformative for the spaces,” said Andrew. www.guthriedouglas.com

This innovative approach to shading was recognised in a number of prestigious awards, including AIA Daylight Project of the Year, Best Interior Lighting Scheme, and Engineering News Project of the Year.

The historic Latvian Museum of Art in Riga, which underwent an extensive renovation, required a different methodology for a similar light problem.

ROOF SAFETY

Roof safety: making the difference Graham Willmott, Chairman of ACR, the Advisory Committee for Roofsafety, explains the role of the organisation and its continuing crusade to improve working practices and minimise the risk of fall-from-height accidents ACR was founded in 1998 by HSE (the Health & Safety Executive), with the aim of establishing and promoting safe practice for the benefit of all individuals accessing roofs.

The Red Book’ ACR[M]001:2014 Test For Non-Fragility of Large Element Roofing Assemblies is based on this drop test developed by ACR.

In 2017/18, 38 fatal injuries occurred on UK construction sites, placing our industry among the highest contributors to workplace deaths. Of these, the majority were the result of falls from height.

It’s a sad fact that each and every one of those deaths was preventable, had appropriate measures been taken.

Defining and communicating those measures is at the core of ACR’s mission – and the organisation has played an important role in significantly reducing accidents to roof workers, since its inception.

ACR was founded in 1998 by HSE (the Health & Safety Executive), with the aim of establishing and promoting safe practice for the benefit of all individuals accessing roofs. Comprised of industry personnel for the safety of industry personnel, its role is not to legislate, but to safeguard.

May/Jun 2019

Working with the HSE (Health and Safety Executive) the following major associations representing roofing trades and product manufacturers are represented on the committee: • BCSA (British Constructional Steelwork Association Ltd) • BSIF,HSG (British Safety Industry Federation/Height Safety Group) • EPF (Edge Protection Federation) • EPIC (Engineered Panels in Construction) • FASET (Fall Arrest Safety Equipment Training) • HSE (Health and Safety Executive) • IoR (The Institute of Roofing) • MCRMA (Metal Cladding and Roofing Manufacturers Association) • NARM (National Association of Rooflight Manufacturers) • NFRC (National Federation of Roofing Contractors)

www.daylightingmag.co.uk

ROOF SAFETY • RIDBA (Rural and Industrial Design and Building Association) • RTA (Roof Tile Association) • SPRA (Single Ply Roofing Association) • WAHSA (Work at Height Safety Association) ACR was formed in response to HSE’s requirement that in order to reduce accidents, all roofing products should be manufactured to be ‘non-fragile’ when fixed. However, at this point ‘non-fragility’ had no specific definition – or a test procedure by which to establish it.

In order to address this dilemma, working to physical requirements established by HSE, the newly formed ACR started work on a test procedure by which non-fragility could be defined.

This constituted a drop test of a sand bag falling onto a roofing assembly fixed to a defined test rig at ground level, that simulated the same effect as a heavy person walking then tripping and falling on to a roof surface.

The conclusion of the work was written up in the first publication of the ACR, entitled ‘ACR[M]001:2014 Test For Non-Fragility of Large Element Roofing Assemblies’. Now in its fifth edition, this document has since provided the HSE approved UK testing and classification system for non-fragility of roofing assemblies, providing the clear benchmarks for manufacturers and installers to meet the required standards.

Since the publication of ‘The Red Book’, ACR has further broadened its commitment to roof safety, with the publication of a series of other widely referenced guides to safe working practices in all aspects of roof work, from the role that designers can play in limiting hazards, to the management and supervision of work at height.

ACR[CP]002:2017 ‘Safe Working on Fragile Roofs or roofs with fragile elements – now in its third edition.

This document is intended to give health and safety advice on how to control the risks involved in working on fragile roofs and is aimed at informing all parties involved in roof work, from product manufacturers to construction and maintenance workers, as well as building owners and property managers. It describes safe practices and procedures to adopt for inspections, refurbishment, repair and replacement of fragile surfaces and recommends acceptable safe techniques to employ to comply with the Work at Height Regulations 2005.

A key part of ACR’s remit is to share its broad knowledge and provide free, easy access to its publications. A new ACR website has recently been launched with this in mind.

Other ACR publications cover specific topics including the use of safety nets, edge protection and the use of safety lines. These topics and publications will be covered in subsequent articles.
