EDITOR’S COMMENT

Hurricane season whips up the climate debate Apparently, a majority of Americans say that global climate change contributed to the severity of recent hurricanes Harvey and Irma, according to a new Washington Post-ABC News poll.

That marks a significant shift of opinion since the early 2000s, when a majority of the public dismissed the role of global warming and said such severe weather events just happen from time to time.

In a 2005 a poll taken a month after Hurricane Katrina ravaged the Gulf Coast and devastated New Orleans, 39 percent of Americans said they believed climate change helped to fuel the intensity of hurricanes.

Today, 55 percent believe that.

Of course it’s impossible to confirm whether or not these hurricanes have directly resulted from man-made climate change, but the case for climate change itself is now watertight from a scientific perspective.

This being so, whatever actions we can take to address this, should be taken with some urgency if we are to avoid further damaging our environment.

Roofglaze Achieves CWCT TN66 & TN67 Class 1 Non-fragility Rating St. Neots based rooflight manufacturer Roofglaze has achieved the best possible non-fragility rating for its range of Flatglass rooflights The Construction Design and Management Regulations 2015 (CDM) determine that designers must eliminate foreseeable health and safety risks during construction, maintenance and refurbishment of buildings.

This has resulted in an increasing requirement for rooflights being specified as non-fragile roofs to ensure the safety of people below the glazed roof and people who may be on the roof.

Roofglaze have recently undertaken further independent tests on their Flatglass range of contemporary glass rooflights, carried out at the world leading Building Research Establishment in Watford, UK. The testing was carried out in accordance with the Centre for Window & Cladding Technology

(CWCT) Technical Notes TN 66 & 67, recognised as the only industry standard for Safety and Fragility for Glazed Roofing.

With the architectural trend for larger and larger single pane rooflights, Roofglaze selected huge single pane units measuring 2700mm x 2700mm and a glass area of 7.290m2.

The CWCT test simulates the impact of a person accidently falling onto the rooflight, or impact from tools and equipment, followed by a static load test to demonstrate the residual strength of the glass.

After three consecutive days of extensive testing, it was confirmed that the Roofglaze Flatglass rooflights conform to the latest CWCT Class 1 non-fragility rating. www.roofglaze.co.uk

Demand for construction workers continues to rise Peace Recruitment Group, experts in the built environment, has revealed that its Trades and Labour Department has doubled in size over the last six months.

Tamara Jaberu, a director at Peace who founded the Trades and Labour Department in January 2012, believes the good news coming out of Peace is further evidence that the UK construction sector is flourishing despite all the recent negative headlines.

Tamara explains: “The construction sector in the UK is definitely in a good place right now, more work is coming into the market and employers are looking to hire. Our trades and labour department exceeded all expectations last year, and as a result we have hired three new recruits since April, meaning we now have a team of six. This enables us to provide a much fuller service to Edinburgh and the Lothians, the Glasgow area and Aberdeen and Dundee. I’m delighted to say we are on course to have a record year again.

Tamara adds: “The major challenge we are facing in Trades and Labour just now is a shortage of candidates.

When I started the department back in 2012, clients had their pick of good quality candidates. However, now this has almost spun on its head and its the skilled candidates who now hold most of the power. Firms can still find the right people but competition is fierce. Employers need to be aware that it may take more time to find the right candidate, they need to be flexible in what they are looking for, and they need to put together as attractive a package as possible.”

The success of the trades and labour department, alongside the huge increase in turnover, as well as the launch of Peace’s new bespoke website, its re-branding and the launch of its new temp division, are all seen as key developments in the recruiters quest to become the recruitment company of choice for the built environment by 2020. www.peacerecruitment.co.uk.

RETAIL SECTOR

The secret to happy customers? Daylight Retailers are constantly looking for ways to provide a better in-store experience for their customers. An often overlooked, but still critical, part of the retail experience is lighting.

Ian Bell of Daylight Delivery Systems Limited, explains.

Tubular daylighting systems deliver high levels of daylight to this forecourt retail space

Retailers are constantly looking for ways to provide a better in-store experience for their customers. An often overlooked, but still critical, part of the retail experience is lighting.

Research has shown that daylight helps to reduce eye strain and increase visual performance, thereby allowing people to perform tasks for longer and with greater comfort. Good lighting, especially natural light, can have a positive impact on the overall shopping experience.

Setting the Shopping Mood The benefits of daylight as a mood

14

Sept/Oct 2017

booster have been demonstrated by multiple studies, and consumers that are happy and comfortable tend to buy more goods, more frequently.

Just as playing soft music helps to set a calm, relaxing mood in retail stores, adequate daylight can create an inviting environment for shoppers.

A California Energy Commission study found that retail stores with ample natural lighting experienced as much as 40% more sales than poorlylit stores. Taking advantage of the positive influence of daylight can help create a retail space where customers will love to shop.

www.daylightingmag.co.uk

RETAIL SECTOR Happier Employees Means Happier Customers Customers aren’t the only ones impacted by better lighting solutions.

Employees spend hours in retail spaces every day, and they are often a customer’s first point of contact with the retailer. Exposure to daylight has been shown to improve employee satisfaction, help reduce on-the-job errors and increase productivity as much as 10%. Reducing the stress levels for employees helps ensure that customer service quality stays high, giving customers a better shopping experience overall.

More light without more heat...

While sunlight often seems like the best solution for creating a well-lit shopping environment, there can be disadvantages; sunlight can also introduce unwelcome levels of heat and potentially harmful UV rays into the building. Uncontrolled sunlight means that retailers can end up facing significantly increased costs for air conditioning/ventilation in order to maintain a comfortably cool working and shopping environment.

For retailers looking to harness the benefits of daylight without the downsides, there are a number of solutions to consider. For example, many rooflight manufacturers offer solar control glazing which reduces UV transmission.

There are also a wide range of solar shading solutions available. Many of these can be linked to light sensors to provide controlled operation. This can make significant reductions in energy consumption for electric lighting.

Tubular daylighting systems provide another outstanding natural lighting solution for retail spaces, with a number of advantages:

More Control over Light Levels – Tubular daylighting systems can provide more consistent and controlled light levels than conventional windows or skylights, so retail areas do not suffer from wide variations in light delivery throughout the day and year.

Lower Energy Costs - Tubular daylighting systems are an energy efficient light source and, unlike direct sunlight, won’t overheat the store, thus retailers save money on climate control and lighting costs. For retailers looking to reduce their carbon footprint, tubular daylighting systems are a compelling option, providing customers with a premium shopping experience, yet saving energy.

A California Energy Commission study found that retail stores with ample natural lighting experienced as much as 40% more sales than poorly-lit stores.

Daylight in Retail Spaces without Access to Sunlight - For retail spaces located in shopping centres, large malls and older buildings, the opportunities for access to natural light are often limited. Tubular daylighting systems let retailers bring the benefits of daylight into their retail space regardless of their location.

MODULAR ROOFLIGHTS – advertorial

LAMILUX introduces ‘Smart Combination’ skylight with integral concertina ladder Now available from LAMILUX UK, the ‘Smart Combination’ is the result of collaboration between LAMILUX Heinrich Strunz Group, a European leader in daylight systems – and attic ladder & staircase manufacturer Columbus Treppen GmbH.

The concertina ladder is compatible with all modular glass and polycarbonate rooflights in the highly respected LAMILUX CI System.

The company believes it is the first to offer such a fully integrated system which provides products of outstanding functionality with greatly reduced lead times compared with conventional solutions.

The components are assembled on site and integrated into the roof as a complete system.

The Smart Combination is easily customisable and can be specified in different lengths, widths and colours, as well as various stair heights and inclinations.

Dan Boughton, Managing Director of LAMILUX UK, said: “Until now, combining convenient roof access with a flat roof window, meant customers having to source components from two or more suppliers and then develop and test a bespoke solution. This new innovation takes away all the hassle and makes specification easy, facilitating a quicker turnaround.”

The LAMILUX CI Modular Rooflight System around which the Smart Combination is based, offers excellent performance characteristics such as energy efficiency through increased airtightness and an absence of thermal bridges, plus unhindered rainwater runoff. The system also offers a wide variety of glazing options.

Development departments of both the companies involved, have been collaborating to achieve the perfect flat roof solution which allows for high levels of daylight transmission while granting convenient and easy roof access. In addition, the solution is both safe and uncomplicated to assemble and install.

Dan Boughton summed up: “Simple ideas are always best, providing the detail execution is right. We’re confident that this new Smart Combination will be a winner with UK specifiers and installers across the commercial and domestic sectors.”

REFURBISHMENT

Rooflight refurbishment & energy saving There is a growing understanding of the role that daylighting can play in saving energy and reducing emissions, but the extent to which rooflight refurbishment can improve building performance is less well documented. Research commissioned by NARM (National Association of Rooflight Manufacturers) and carried out by Elmhurst Energy, has shed more light on the matter.

At the beginning of this century, the government set about improving the building stock of both new and existing non domestic buildings by addressing the Building Regulations Part L to reduce carbon emissions, by saving energy consumption on heating and lighting.

In the early phases, the emphasis was on improving the building fabric by improving the building’s insulation. The initial focus solely on insulation levels erroneously led to pressure to reduced glazed areas (windows and rooflights) as they were less well insulated than the opaque structure.

NARM was already involved with theGovernment at the time and was

18

Sept/Oct 2017

able to demonstrate that reduced levels of natural daylight in buildings resulted in an increase in overall power use due to the need for more electric lighting during the day which far outweighed any savings in heat energy achieved by reducing glazed area.

Independent research was able to demonstrate that the optimum level of rooflighting (in appropriate buildings) was 15-20% of the floor area. This was incorporated into the energy calculations used by Part L2 togetherwith the inclusions of improved lighting system efficiency.

It was also noted that the potential benefit offered by good daylighting levels was often wasted when electric lights were left on unnecessarily;

www.daylightingmag.co.uk

REFURBISHMENT automatic control of lighting systems was also incorporated to ensure the potential energy savings offered by natural light were fully captured.

The Elmhurst Energy report focuses on the existing building stock of non domestic buildings and demonstrates that refurbishing/increasing rooflight areas to 15% and improving the efficiency of the lighting systems and control systems can be very effective with payback in just a few years.

Medium term savings could be very substantial for the landowner and/or tenant. There is an added benefit on top of the financial and carbon savings – good, natural daylight in buildings improves the mood of people in the building and evidence shows they work more efficiently.

Different building types The report has been based on analysis of three types of existing non domestic buildings to examine the effects of increasing the quality of day lighting and increasing the efficiency of electric lighting on both running costs and carbon emissions.

The buildings examined are real life examples of an industrial building, a retail building, and a school. For each building the effect of improving the level of daylight (by use of improved rooflights and increased proportion of rooflights), improving the efficiency of the electric lighting system and improving the control of the lighting system have all been studied.

Significant savings in both running cost and carbon emissions can be achieved using these improvements in each building type. The report details the overall savings available, together with the savings achieved by each measure independently, for each building type.

In all three example buildings, the

www.daylightingmag.co.uk

effect of improving daylighting through rooflights (by a combination of using more efficient modern rooflights, fitted to an appropriate percentage of the floor area) in conjunction with the existing electric lighting system, offers a significantly greater saving (typically twice as great a saving) than improving the efficiency of the electric lighting system in conjunction with the existing rooflights.

However, the greatest savings are achieved by a combination of all measures: improving the rooflights to increase the amount of light entering a building and adding automatic lighting controls to modern, more efficient light fittings.

Each building type shows significant savings in both running cost and carbon emissions can be achieved...

The report details the overall savings available, together with the savings achieved by each measure independently, for each building type.

Example: the industrial building – overall savings The results show that for an example industrial building, total carbon emissions could be reduced by 26% and total operating costs could be reduced by 30%.

These savings equate to: • a reduction of 28.7 kgCO2/m2/yr – in this example giving a building-wide saving of 28529.81 kgCO2/year • a reduction in total operating costs of £5.92/m2/yr – in this example giving a building-wide saving of £5884.89 per annum These overall saving comprise both reductions in use of the heating system (through better insulated replacement rooflights) and reductions in use of the lighting system (through better control systems, more efficient electric lights, and better availability of natural light through replacement rooflights).

Reduced use of the lighting system accounts for 77% of the total saving in carbon emissions and 82% of the total cost saving, with the remainder coming

and automatic control of the lighting systems.

The overall savings can be broken down further:

The results can be correlated into the graph above, to show the impact of the improvements on the running costs of the building.

Improvements to the rooflights and lighting control systems (where this is technically possible whilst retaining existing electric lights) offers: • savings of 23% in carbon emissions (25.8 kgCO2/m2/yr) • savings of 26% in total running costs (£5.22/m2/yr) In this example, improvements to electric lights and lighting control systems whilst retaining existing rooflights offers: • savings of 14% in carbon emissions (15.3 kgCO2/m2/yr) • savings of 18% in total running costs (£3.64/m2/yr) However, to gain the full potential savings requires improvements to all 3 aspects: rooflights, lighting systems,

20

Sept/Oct 2017

Retail and school buildings The other building types covered by the report also demonstrate excellent results. The Retail premises – a large DIY/home improvement store provided results broadly consistent with the engineering premises.

Slightly lower savings were achieved in the rooflit areas of the school (savings in running costs of £2.92/m2/ yr, and savings of CO2 emissions of 14.7 kg CO2/m2/yr), primarily because significant sections of the rooflit areas are also well lit by windows, reducing the effect of improved illumination through rooflights.

The ability to keep the school functioning while the work was completed meant minimum disruption to staff and students. This meant there was minimal use of temporary classrooms during the works, thereby saving time and money.

The two fully replaced elevations are a perfect example of how Kalwall can be used for the refurbishment of old and failing cladding and for aged buildings.

REFURBISHMENT – advertorial The two fully replaced elevations are a perfect example of how Kalwall can be used for the refurbishment of old and failing cladding and for aged buildings. The new façades allow floor to ceiling diffused and healthy daylight to flood the interior while providing privacy for students and removing any distractions. An integrated row of clerestory windows provides ventilation and limited views to the outside.

Studies show there is a high correlation between daylighting and increased human comfort. Kalwall eliminates all shadows and glare and the stark contrasts of light and shade which not only reduces eye fatigue but also enhances concentration.

The system also enhances simplicity by doing away with the need for blinds, curtains or solar control. Even on cloudy days, the interior is flooded with natural daylight, which means less artificial lighting and, because Kalwall is highly insulating, energy costs are reduced. The standard Kalwall 70mm thick panel offers insulation up to 0.28W/m2K - equivalent to a cavity filled solid wall.

The advantage of it being fabricated off-site meant disruption and time on-site were minimised while the combination of high insulation, natural daylight and ventilation means reduced energy costs”. www.structura-uk.com/kalwall

REFURBISHMENT

The importance of air circulation and natural daylight in Public Sector buildings Could one seemingly simple specifying decision affect the quality of life and future health of a buildings inhabitants? When that decision is about rooflights the answer is a resounding yes. The reasons can be found in the air we breathe and the light we see.

In recent years there has been a worrying trend in public sector properties. With the aim of cutting heating costs and avoiding an initial investment in roofing work, existing rooflights were being covered up with false ceilings. The thinking was that these ageing skylights leaked warm air out and drew draughts in. It would be cheaper to hide them and forget about them than replace them.

But what does that really do?

Unseen water leaks and expensive subsequent repairs are the very least of the problems this easy fix creates.

Boarding over a rooflight does the very opposite of what current building standards demand – it reduces fresh air and increases reliance on artificial lighting.

Yet the Condition Improvement Fund can help academies and 6th form colleges replace rooflights which are proving problematic. To help win that funding Whitesales, the UK’s leading supplier of high-performance rooflights, offers free site surveys, condition reports, costings and advice.

How much does fresh air matter?

The air outside comprises less than 0.04% carbon dioxide (CO2). The air we exhale has a concentration reaching 5.6%. Put dozens of people together indoors – as we do in classrooms,

24

Sept/Oct 2017

hospital wards and office buildings – and CO2 concentration will continue to rise over the course of a day.

What are the effects of excessive CO2?

Drowsiness, lack of concentration, reduced energy and awareness and lower productivity and performance are virtually inevitable. The worst case scenario, where CO2 reaches dangerously high levels, includes frightening side-effects from dizziness

www.daylightingmag.co.uk

REFURBISHMENT and confusion to low blood pressure and cardiac arrhythmia. It’s no surprise that CO2 is classed as a substance hazardous to health.

Link a CO2 monitor and a rooflight fitted with ventilation, and the improved air quality will help people perform at their best.

How much does daylight matter?

The effects of natural light have been the subject of numerous studies from all around the world. These are some of their findings: In schools, increased natural lighting leads to longer attention spans, better behaviour, reduced sickness days, increased energy levels and improved academic results.

In hospitals, increased natural lighting

has been linked to stronger immune systems and faster and better recovery rates.

In workplaces of all kinds, increased natural lighting has been proven to improve the bottom line, with better productivity, performance, staff retention and recruitment, morale, motivation and teamwork, and reduced turnover and absenteeism.

So when you’re considering cost-cutting measures for public sector buildings, or requesting a refurbishment, remember those simple but cumulatively important facts. The more daylight and fresh air that’s available, the better we all feel and perform.

DAYLIGHT FOR DRAMATIC EFFECT

Stained glass windows keep ahead of the curve Richard Blausten of the Worshipful Company of Glaziers & Painters of Glass explains how the ancient craft of making stained glass has embraced the latest technology and been able to leap to the forefront of modern building use.

The use of stained or painted glass windows in buildings remains as important a feature of buildings today as it was in the past, where then, as now, its decorative function was often implemented in the construction of new builds.

In medieval times onwards until the Reformation and Cromwell, stained glass artists and workmen were busy producing and installing stained glass windows in new cathedrals and churches. As the number of these expanded so did the stained glass craft. In parallel, again then as now, stained glass decoration was added

34

Sept/Oct 2017

to existing buildings in a spirit of enhancement.

The idea of stained glass windows being associated with official or high status was taken up by the nobility and wealthy merchants through Tudor times, and then saw a resurgence in the early 19th century, through Victorian times until the Second World War, with many new churches being built, but also town halls, public libraries and other municipal buildings.

If the building had stained glass it was special went the thinking, so owners of theatres and even public houses latched onto the idea.

www.daylightingmag.co.uk

DAYLIGHT FOR DRAMATIC EFFECT Being a stained glass craftsperson has always been competitive. Originally pressures on the craft came from outside - from vested interests in the early Middle Ages through to the early 1800s seeking to achieve monopolies on glass and lead. To combat these attempted monopolies the Guild of Glaziers was formed in the Middle Ages, with a mention of its existence in the list of guilds occurring in 1328.

The Guild of Glaziers became the Worshipful Company of Glaziers, i.e. a City livery company, in 1638.

What is now the Worshipful Company of Glaziers & Painters of Glass operates to safeguard and develop the stained glass craft, and in latter days has included leaders from the engineering, construction, glass manufacturing and architectural sectors as its Masters.

Today the competition is between the artists themselves (and their studios) as they pitch for projects.

Paradoxically, it is the conservation (repair, cleaning and preservation) of stained glass that provides one of the most important aspects of the combination of artistry and technology that is so much a feature of modern stained glass work.

The restoration of the huge stained glass Shakespeare Window in Manchester Central Library as part of an overall £100 million Manchester City Council refurbishment and extension project is an example. Conservation and repair company Recclesia worked on the window under the overall management of contractor Laing O’Rourke. The embracing of new technology for that project is mirrored elsewhere in stained glass restoration, such as digital photography, electronic recording techniques and “isothermal” protective glazing.

However, it is in modern living and new build situations that the stained glass craft is showing the most exciting

www.daylightingmag.co.uk

initiatives - and from a variety of starting points. There are those artists and studios specifically catering for house owners. Walk down Kingston Road in South London on the way to South Wimbledon tube station and there, among the dry cleaners, takeaways, restaurants and kitchen equipments shops, is a shop front for Coriander Glass, producing for today’s home owners bespoke Victorian, Edwardian, art deco and modern stained glass windows - quite apart from restoring windows in Hampton Court Palace.

Then there is the Dutch born but now Worcester-based Frans Wesselman.

A painter, etcher and stained glass artist who is increasingly in demand, he is only too pleased to take his talents into people’s homes where he is commissioned to undertake a particular artistic role. One of his favourite commissions was to produce a window for a couple’s bathroom depicting a scene from their Canadian holiday; he was absolutely in tune with their wish to revisit their Canadian experience every time they looked out of their window in England.

Paradoxically, it is the conservation of stained glass that provides one of the most important aspects of the combination of artistry and technology that is so much a feature of modern stained glass work.

A recent member of the Glaziers’ Company is Ukrainian artist Oksana Kondratyeva. Brought up in the old Soviet Union with a technical and mathematical education, she is now based in London and epitomises the new thinking which is taking stained glass to be ahead of the curve when it comes to utilising light.

She explains: “Stained glass or architectural glass is, first of all, the art of controlling light and transforming the space. The most exciting task is the construction of the architecture of light, i.e. the building up of a new space within the given architectural space. I look at this as a way to go beyond three-dimensionality to explore the secrets of its inner space. I think

the artist who works with glass can be viewed as a scientist conducting an experiment with light.”

The work being done at the moment to generate electricity with decorative glazing on the outside of buildings is definitely keeping the stained glass craft ahead of the curve. As Dorothy Hardy, a research fellow with a strong interest in sustainable energy generation at Nottingham Trent University, points out: “Solar cells can be used in a great variety of glazing designs. Inclusion of solar cells within glazing is a switch from glazing being a passive system to an active electricity generator. Entire building exteriors provide potential areas over which solar cells can be placed, but glazing provides one area where retrofitting is relatively straightforward, giving the opportunity to add decoration and interest both within and on the exterior

36

Sept/Oct 2017

of buildings.”

The use of fluorescent dyes, coloured glass, paints films and decals when solar cells face outward and are viewed from a distance means, according to Hardy, that “the full palette of colourful media which is normally available to glass artists and designers is still applicable when designing glazing schemes that contain solar cells.”

It is fitting that the Canadian glass artist Sarah Hall, the renowned exponent of using solar art glass to produce both a striking visual impression and energy, e.g. the “Lux Nova” solar art glass wind tower in Vancouver, was originally apprenticed in London to the late Lawrence Lee, a Past Master of the Glaziers’ Company. worshipfulglaziers.com

Painting with light Architectural stained glass artist Stuart Low paints a different picture of daylighting Stuart Low has maintained a close connection to architectural glass for the past twenty years since graduating from Swansea school of art, and for the past ten years has focused his practice on commissioned projects for the public realm.

The breadth of work he has undertaken has been wide ranging, from traditionally crafted stained and painted glass windows to works that are made using the most up to date processes: digital print on glass, screen printing of transparent and translucent vitreous enamel, mouth blown antique glass and assembled glass, all of which are integrated into modern glazing systems.

Stuart’s work is informed by a variety of criteria including the location, architecture, purpose or use of the building, client needs and brief.

Innovation and forward thinking are key to all projects. Common influences throughout may also be linked to the artists parallel practice of painting and printmaking, which cross with and feed into the design process for glass.

Stuart is a member of the Somerset Guild and Devon Guild of Craftsmen and enjoys close contact with the making process in his Bristol based studio. Here, he develops work on a regular basis for galleries and exhibition.

In addition, collaborations are also made on projects with specialist glass

38

studios both in Germany and the UK.

This relationship with fabricators allows him the freedom to experiment and develop the most surprising and often technically challenging works, on a large scale if the commission demands.

Stuart’s commissions are typically connected with local health authorities, architects and developers, art consultants, schools, churches, chapels, and private clients www.stuartlow.co.uk

CONTROLLING HEAT & GLARE

Automated Shading – A fresh look at existing innovation Existing innovation? That does not make any sense! However when innovation has not been widely accepted as an answer to an ongoing issue, it should still be viewed as innovative. By Rob Booth, Specification Manager, VELUX.

London’s famous Shard, in which fully automated controls supplied by Mechosystems were incorporated into the spine of the building.

As needs grow, extra functionality can be added

Unobstructed Glare and Heat is a base issue in the design of any commercial space, alongside Healthcare and Education buildings.

Of course, we could design without glass, but that isn’t going to happen, so Glare and Heat remains. We also agree throughout the design community and associated academia that Daylight is an inescapable benefit

to the Human condition and should be optimised in any space……back to potential Heat and Glare again. So how do we utilise the big ball of heat and light in the sky to maximise Human benefit, but minimise utility cost within the building?

We are seeing the advent of “Smart Glass”, which can react to the Sun automatically to protect occupants, and

www.daylightingmag.co.uk

CONTROLLING HEAT & GLARE whilst this really exciting new approach is potentially the future of building response to the issues at hand, there are still limitations that need to be overcome to make it a true solution that is adaptable to all conditions and needs. Whilst we as a community Design and Build for the future, we are constrained to materials available to us now, or in the very near future.

Automated Solar Shading has been available for some time, however tends to be viewed as a luxury, reserved for the keynote buildings with budget to spare, a misconception that should be addressed. There are any number of ways to shade a space, from blinds (both vertical and horizontal slat) to Brise Soleil, external fins that are either fixed or moveable, to fritting on the glass itself. In this instance I am concentrating on internal flat fabric Roller shades, one of the most adaptable ways of dealing with a dynamic issue, i.e the movement of the sun.

The engineers amongst you will be thinking it is more effective controlling the Sun with external solutions, and you would be right, however this can compromise the design aesthetic, it can also reduce or remove the view for the occupant (back to that pesky human condition and the need for connection to your environment) and can be costly to install and maintain.

LEED or BREEAM recognition Installing Roller Shades is a relatively low cost, simple installation, and will tick the necessary boxes for LEED or BREEAM recognition as Daylight response, however this relies on interaction to be effective. Almost anyone suffering from direct or indirect Glare, or feeling the radiant component of the Sun as it passes across their body will get up and make the effort to bring the Shade down to

www.daylightingmag.co.uk

control the discomfort. As previously mentioned, the Sun is dynamic, as is the environmental conditions surrounding any given building, so as the Sun moves to a position that no longer poses an issue, or cloud cover removes the risk, will that same person get up and open the Shade accordingly? Probably not, because we have designed very clever automated lighting systems that compensate for lack of light and ramp up to give a consistent, comfortable lux level on the working plane. The issue caused here is that we are burning electricity when it is not required, pushing the utility cost of operating the building higher and higher. Those same Shades could be controlled with motors, or actuators, and controlled by switch or remote control, which increases the chance of interaction, however the capital increase in the installation does not pay back unless that interaction is effective. This leads us into the world of an automated response.

Automated Solar Shading has been available for some time, however tends to be viewed as a luxury, reserved for the keynote buildings with budget to spare, a misconception that should be addressed.

Design considerations It is now an entirely standard concept to map a building in orientation, geometry and exact location to build a profile of exactly how the Sun will impact the façade all day every day.

Whilst the Sun’s altitude and azimuth is constantly changing, it is predictable.

Utilising algorithms designed to convert that information, and presuming a clear sunny day, zones are created throughout a building, where the maximum solar penetration can be dictated by the control of the Shade position in the window. Other elements need to be considered, such as the correct Shadecloth both in colour and composition, and the use of the space internally, however different reactions are possible across the same elevation, even on the same floor dependant on the needs of the building.

CONTROLLING HEAT & GLARE

One overlooked benefit is the consistency it brings to the appearance of the building; the shades being aligned so not creating the checkerboard effect you see in so many buildings detracting from the appearance of the original intent.

Allowing for local conditions This proactive response does not consider local micro-climactic conditions, so a reactive system is introduced to allow for this also. A single sensor, mounted on the highest part of the building is looking at these local conditions, and overrides the system accordingly. Cloud cover will create a reaction to raise the shades fully, to maximise the available light, and will revert as the cloud moves on, with the system returning to the pre-set positions. Most sensor driven systems rely on a lux sensor, which only sees visible light, giving a minimal response to Glare, however true automated response systems use a radiometer, which considers the Infrared and UV elements of the Solar wavelength to give an accurate response to the local conditions. Delays can be built in and adapted to remove the chance of shades bouncing up and down all day causing a distraction to the occupant.

vicinity to map shadow cast on your building. Any area in shadow caused by a permanent fixture can have the shades raised during the times of day the shadow is cast‌.as it does not matter whether the Sun is obstructed by cloud or not. Another possibility is modelling first reflection of surrounding buildings to see if that has an impact.

Traditionally, North facades are ignored for shading purposes, however in densely populated cities, highly glazed buildings opposite that façade will reflect glare, this can be accurately added to the building response system.

Payback and savings for building owners I go back to the point that this is currently reserved for those keynote buildings, and while they have given us the most accurate data to show the savings available in operating the building, this is scalable. Not all the above need to be implemented in every building, cherry picking per the needs and budgets is a sensible approach. Yes, it adds to the cost of build, but can be one of the few systems in the building that offers a very realistic payback, and future savings for building owners or occupants. The New York Times building, whilst no longer occupied by them, is one of the most studied publicly available pieces of ongoing research that is worth a look.

I remain excited at the future of shading and the daylight strategy of buildings, especially in my new role with Velux Modular Skylights, but still have a concern that so many buildings do not achieve the daylight autonomy they were intended to receive to the detriment of all.
