EDITOR’S COMMENT

Putting daylight on the sustainability agenda A recent study has shown that electric lighting consumes approximately 18 percent of the UK’s electricity: roughly 58,000 terawatt hours (TWh) per year – and commercial lighting accounts for seven tenths of this electrical consumption.

businesses to combat climate change.

According to Government figures, a surprising 35.5 percent of UK energy came from renewable sources in Q2 2019. That’s positive news, but with the remaining 64.5 percent coming from other less ‘clean’ sources, electric lighting is clearly a significant contributor to UK CO2 emissions.

The good news is that sustainability as a whole appears to finally be gaining some real ground on the agendas of governments around the world (with one or two notable exceptions).

It doesn’t take a rocket scientist to see that reducing the need for electric lighting during daylight hours and integrating daylighting with automatic lighting controls can take a big chunk out of these figures.

This being the case, I am continually frustrated by the tiny amount of column inches devoted to the benefits of daylighting in the wider media – and even in many publications devoted to helping individuals and

In my view, it’s a big oversight and a missed opportunity – particularly in view of the health benefits of well daylit interiors and the simple fact that daylight is free!

In light of so many disturbing recent weather events and reports on global warming and its effects, lets hope its not too little, too late.

Paul Bennett paul@daylightingmag.co.uk

This issue of Daylighting Magazine carries two articles directly covering the subject of energy saving with rooflights, as well as a mix of case studies and articles in which the benefits of daylighting are highlighted within specific building types and sectors.

Urban regeneration construction ‘creating opportunities’ Square. As well as 330 flats and a new public space, it will involve the pedestrianisation of part of the city’s historic thoroughfare, Union Street (Glenigan Glenigan Project ID: 10199112).

In Leeds, John Sisk has recently been appointed as the civils contractor on a £30 million city council scheme of public road and transport improvements to create a series of new gateways into the city centre. Work will start at the end of this year and should run for 14 months (Glenigan Project ID: 18347626).

Construction research & information specialist Glenigan has stated that “The ‘end of austerity’ should help sustain the healthy levels of spending on regeneration projects across Britain’s towns and cities which are proving a good source of new urban regeneration construction work”.

Schemes to revive urban areas with new residential projects, improved transport and pedestrianised high streets are helping to buoy up public and private sector construction workloads.

The various government regeneration spending initiatives which featured in the last Budget are translating into new construction work in many regions

and the signs are that more will follow.

Spending on the Transforming Cities Fund is set to climb from £140 million in 2018/19 to £355 million in this financial year and to £1,010 by 2021-22. Meanwhile, spending on the Future High Streets Fund is set to grow from £5 million this financial year, to £75 million in 2020-20, to £240 million by 2022-23.

Glenigan Construction Data highlights the extent of major city centre regeneration projects which are in the construction pipeline nationally.

In Aberdeen, tenders have recently been returned and work is set to start next summer on a £20 million city centre redevelopment at Queens

Elsewhere, Newcastle City Council is set to embark on a £23 million town centre redevelopment. It involves the construction of a new shopping area on Pilgrim Street and the pedestrianisation of the city’s Blackett Street, as well as the creation of a new events space.

Work is set to start on the project - which is at the pre-tender stage - next Spring and continue for two years (Glenigan Project ID: 17421569).

Further south in Oxford, work is set to start later this year on the city council’s £8 million pedestrianisation of the city’s Broad Street which will involve the creation of a new university square. Work on the scheme, which is at the pre-tender stage, is set to continue for 12 months (Glenigan Project ID: 98441283). www.glenigan.com

All new public buildings in Scotland ‘to be zero carbon’ part of a focus on tackling climate change.

Scottish First Minister Nicola Sturgeon has announced that all new public buildings built in Scotland are to be be built to net zero carbon standard to ensure they ’meet the challenge’ of the climate emergency.

The measure was one of a number of environmental initiatives unveiled by her on Wednesday 4th September as

In addition to working on a new ‘Net Zero Carbon’ standard for all new public buildings, the government also said it would oversee a ‘fundamental overhaul’ of building regulations to ensure that from 2024 all new homes use renewable or low-carbon heating. A new consultation will include measures to improve energy efficiency and the quality of construction and will be accompanied by a planned £30 million investment in renewable heat projects.

Ms Sturgeon also revealed plans for a £3 billion Green Investment Portfolio, and a ‘Green City Deal’ for cities and regions. She said the transition to net zero will be the primary mission of the Scottish National Investment Bank.

Plans to clean up Scotland’s rail network and introduce a fleet of ultra-low-emission buses were also announced.

Ms Sturgeon said: ’Earlier this year, I acknowledged that Scotland – like the rest of the world – faces a climate emergency. We are now committed to achieving net-zero greenhouse gas emissions by 2045 at the latest – earlier than any other UK nation. ’This year’s Programme for Government is an important part of our response to the climate emergency, containing measures which will reduce emissions while supporting sustainable and inclusive growth.’

The commitments were outlined in the Scottish National Party’s legislative programme for 201920, entitled ‘Protecting Scotland’s Future’.

Report Highlights Connection Between Insulation Performance and Daylighting New research from leading building consultants, Peutz B.V., has revealed that by using higher performing insulation within rainscreen and cavity walls, it is possible to reduce construction thicknesses and achieve noticeable improvements in internal natural light levels.

Its findings are explored in full in the updated Daylighting White Paper from Kingspan Insulation, available for download from: www.kingspaninsulation. co.uk/daylighting.

www.daylightingmag.co.uk

The analysis looks at the change in the average daylight factor (ADF) for a room when premium performance Kingspan Kooltherm insulation is used compared with mineral fibre insulation.

For each scenario, comparative constructions were designed to achieve an identical U-value.

This required a greater insulation thickness, and consequently wall and reveal depths, for the lower performing mineral fibre insulation constructions. A number of window arrangements were also

considered for each scenario.

The findings showed that in all scenarios, the constructions using Kingspan Kooltherm insulation achieved improved ADF’s.

In addition, all results with the Kingspan Kooltherm products exceeded the minimum daylighting criteria from BS 8206-2: 2008 for bedrooms and living rooms. info@kingspaninsulation.co.uk

Manchester’s Low Carbon Homes Ambition BEIS trials and local policy and supply chain development.

On November 14th 2018, Manchester City Council adopted new science-based climate change targets on behalf of the city, to rapidly cut emissions from 2015 levels by 50% by 2022, 83% by 2030, and down to zero by 2038.

The city’s ‘Draft Zero Carbon Framework 2020-38’ document confirmed that – for domestic property – this would involve reducing energy demand and shifting to lower carbon heat sources, lifting families out of fuel poverty and saving residents money on their energy bills, as well as reducing greenhouse gas emissions.

A year later to the day, Cogent Events will open the doors to the North West edition of Low Carbon Homes - its nationwide regional event series - in Manchester. Working with Manchester City Council, Manchester Climate Change Agency and wider stakeholders, the event’s programme has been curated to ensure that speakers and delegates at the 14th November event tackle the particular challenges of retrofitting existing housing stock, while helping to develop the Zero Carbon Framework 2020-38,

Jonny Sadler, Programme Director of Manchester’s Climate Change Agency, and speaking on the Low Carbon Homes programme, emphasises that “Bringing Manchester’s existing housing up to a zero carbon standard is a vital component of our zero carbon ambition, which will not only improve the wellbeing of our residents, but will stimulate a retrofit market, boosting our local economy.

“We need local businesses, homeowners, landlords, Manchester City Council, Greater Manchester, Government and others to come together to help create an ambitious programme of zero carbon improvements across the city. The Low Carbon Homes event is a key part of kickstarting this hugely exciting work.”

Aimed at architects, heating engineers, local authorities, landlords, contractors and related sector professionals, the free-to-attend event features plenary sessions, practical workshops, training and exhibitors covering interests such as the fabric first approach, heat pumps, heat system design,

Heat Pump Focus: Reflecting the growing interest in the electrification of heat, Heat Pump Focus is a free-to-attend event featuring exhibits, talks and presentations within Low Carbon Homes providing all-day access for invited visitors and delegates. The new initiative is supported by the Ground Source Heat Pump Association, the Heat Pump Association, manufacturers and designers.

“The Manchester event is set to be our largest Low Carbon Homes event so far, and we’re delighted with the support we’ve received across the city. The ambition, dynamism and commitment of our supporters and wider community is truly inspiring. If there is a city in the UK that can get to Zero Carbon by 2038, it’s Manchester… and we’re honoured to be playing a part in helping make that happen” - Graham Lock, Founder, Low Carbon Homes lowcarbonhomes.uk

DAYLIGHTING IN RETAIL

Daylighting in retail: saving energy & boosting performance Tom Bates, Managing Director of Lareine Engineering, looks at how daylighting can bring important benefits to retailers in today’s demanding economic climate

It’s no news that the UK’s retailers are under growing pressure from a variety of sources. The continuing surge of relatively un-regulated internet sales, balanced against increasing rents and other costs, are making life difficult for the high street – from independent stores to national and international chains.

Against this backdrop, carefully considered daylighting in stores can play an important role in addressing two key areas of concern for retailers:

16

Sept/Oct 2019

first, by providing the optimum environment for shoppers, with the best possible presentation of goods to maximise sales opportunities; and second, by delivering reduced energy costs.

For these reasons, now is a good time to re-visit some research on these subjects. The findings of which are perhaps now more pertinent than ever, due to the prevailing economic pressures on retailers.

www.daylightingmag.co.uk

DAYLIGHTING IN RETAIL Better shopping experience = better returns for retailers First, lets reference a landmark document produced over a decade ago in the United States, by the highly respected HMG, Heschong Mahone Group. This paper, entitled ‘Daylight and Retail Sales’ was based on a study of 73 store locations in California, of which 24 were daylit primarily by diffusing skylights.

To calculate the overall effect of more daylight on sales, HMG first calculated the effect of daylight on each individual store, taking into consideration a variety of factors and variables specific to each store. They then summed the effects on all daylit stores and divided by the sum of all sales for those stores, to calculate the ‘net daylight effect’, or the average predicted effect on sales for adding daylight to any store in the sample group.

of-mouth in generating increased footfall resulting from the improved in-store experience that can result from daylighting.

Lower energy consumption: a win-win situation Independent research carried out in 2005 by DeMontfort University and referenced in the National Association of Rooflight Manufacturers’ (NARM) Introduction to natural daylight design through rooflighting, proved conclusively that rooflights save energy. Since then it’s been widely understood that a well designed

“...this calculation predicted an average increase in sales associated with the presence of daylight, of between 1% and 6%. ”.

The results of this calculation predicted an average increase in sales associated with the presence of daylight, of between 1% and 6%. In the vast majority of retail environments this represents a significant longterm benefit when balanced against the investment required to introduce daylight.

Happy customers: success breeds success The reasons for this projected sales increase can be attributed to a number of factors, including better presentation of goods at point-of-sale, the tendency for shoppers to relax and remain longer in daylit environments and better performance of sales staff within the store.

It should also be noted that for refurbishment projects, this calculation does not appear to take into consideration the potential effects of marketing and customer word-

The combination of these factors means that including rooflights can offer a dramatic reduction in a building’s total energy consumption and the emissions of CO2 associated with this energy use.

report by Elmhurst Energy. Three buildings were assessed in the report, one of which was a Homebase store.

The results showed that by upgrading rooflights and lighting controls in this application, total carbon emissions could be reduced by 29% and total operating costs could be reduced by 33%.

This reduction in energy consumption and emissions offers a number of advantages. Obviously, any reduction in building running costs brings a measurable business benefit as well as playing a role in helping to meet government climate targets. For retailers, this fact can also provide the spin-off benefit of a positive marketing message. Retailers in all sectors are under pressure to make public their ‘green credentials’. Reducing harmful emmissions by minimising energy consumption in stores is as relevant to today’s sustainability-conscious shopper as responsible sourcing and recyclable packaging.

In addition to the benefits outlined above, installing rooflights can also provide options for natural ventilation for comfort of building occupiers and/or as part of a smoke ventilation system. Manual or automatically opening rooflights and louvre ventilators are two options which can be supplied in a variety of designs and formats. Lareine Engineering can provide a complete design and installation service for rooflights and ventilation – drawing on many years service to the UK’s retail sector.

Meeting rooflighting challenges in refurbishment Rob Hamblen, Sales & Marketing Director at Whitesales, explains the challenges faced by manufacturers and contractors in complex refurbishment projects, and how logistical planning and effective communications are the key to success.

It could be said that it’s obvious that refurbishment projects, specifically for old and historic buildings, present many more challenges than new build. Refurb projects require working with existing systems and around existing structures, often in confined spaces and with limited access.

Problems which are impossible to predict are more likely to occur when work begins on a refurbishment project, potentially resulting in untold slippage to the schedule. Often however, the biggest challenges

are the same as with new build – coordination of multiple trades and precise management of site and installation schedules.

The complex nature of the roof structure and extensive project scope make Bristol University’s Fry Building case study an ideal reference point for highlighting the challenges and considerations arising in refurb works. The nature of pre-existing roof design for many buildings is such that numerous materials are present and in between them are a variety of interfaces – slate to membranes, liquids to membranes, lead flashing and roof glazing integrated with all these materials, for example. Often the refurbishment scope will detail product specifications but not how these material interfaces will be designed and executed. The very points of likely failing, the interfaces, become the place where the least care and the least experience is applied. When the project is completed, the result can provide a perfect aesthetic with hidden issues just waiting to arise.

A large part of any refurbishment project will also focus on meticulous analysis during design and planning.

Investigation of the existing structures, implications of any additional weight loading, wind uplift calculations and required fixing methods, for example.

Consideration of available features to achieve required U-values as well as detailing of all roof penetrations and

The ÂŁ19m refurbishment of the Fry Building, involved extensive refurbishment of the roof structure and existing roof glazing and rooflights.

Work on the Grade II listed building included replacing the northlights

and bespoke ridgelight in the flat roof area, vertical aspects in the complex sawtooth section, sympathetic replacement of historic units, L and U-shaped integrated continuous rooflights and a challenging custom, high-specification walk-on installation.

The sawtooth section of the roof is a

REFURBISHMENT dramatic and eye-catching feature.

William Fairbairn, a British engineer and architect, is often credited with the very first sawtooth roof design which was termed the “shed principle� in around 1827. In a sawtooth roof, there are a series of ridges that have dual pitches on each side. The vertical aspects are fitted with glass panels that face to the North to allow filtration of the light and reduce direct exposure. The new continuous roof glazing installed exactly matches the pre-existing in appearance, whilst delivering improved performance and opening panels for natural ventilation.

Fragility considerations were of high importance for the flat roof area. The installation schedule also presented many challenges. A carefully planned, staged installation of the main units and flashings allowed for works to be completed more easily. Temporary weathering was utilised to facilitate this staged process.

Another particularly challenging element of the scope of works were the technical requirements for the walk-on unit installed above the new lecture theatre. It required a collaborative working approach with the structural engineer to ensure the specification was precisely defined.

The installed unit features bespoke weathering and printed vinyl dots on internal glass layer, to offer diffused light to the area below.

For contractors undertaking refurbishment projects, the logistical challenges that these projects present are numerous. Successful completion will be contingent upon strict management of communications, plans and on-site coordination, as much as on selection of the appropriate products and actual installation.

ROOFLIGHTS & SUSTAINABILITY

Understanding rooflight U-values and how they affect building performance By the Technical Committee of NARM, the National Association of Rooflight Manufacturers

The increasing focus on sustainability across all areas of the construction industry, has led to a raft of marketing campaigns featuring product performance metrics and environmental credentials. The majority of these are factual and backed by testing and independent approvals and ratings. However, there are unscrupulous suppliers making false or exaggerated claims and others presenting confusing messages which blur the facts.

Rooflight U-values are a case in point.

U-values (sometimes referred to as heat transfer coefficients or thermal transmittances) are used to measure how effective elements of a building’s fabric are in providing thermal insulation. In other words, how effective they are at preventing heat from transmitting between the inside and the outside of a building. U-values

www.daylightingmag.co.uk

are measured in watts per square metre per Kelvin (W/m²K). For example, a rooflight with a U-value of 2.2, for every degree difference in temperature between the inside and outside of the window, 2.2 watts will be transmitted every square metre. The lower the U-value of an element of a building’s fabric, such as a rooflight, the more slowly heat is able to transmit through it, and so the better it performs as an insulator.

As the need to reduce CO2 emissions becomes more urgent due to climate change, overall building performance measures and energy consumption have become more important, and standards (such as the Building Regulations Approved Document L: Conservation of fuel and power) have required lower and lower energy consumption and CO2 emissions.

These considerations have driven

ROOFLIGHTS & SUSTAINABILITY changes in the design of buildings, both in the use of materials, the makeup of building elements such as cavity walls and glazing, and the overall design of the building.

and reduces daylight levels within the building, and can reach a point where the resultant increase in lighting energy outweighs the savings in heating energy.

In broad terms, the lower the U-value of a building’s overall fabric, the less energy is required to maintain comfortable conditions inside the building. But it is vital to note that thermal considerations are not the only considerations for overall energy consumption, and lighting energy demand is often the primary consideration. Use of daylight through rooflights and windows can dramatically reduce overall energy use, even if the glazing is less well insulated than opaque areas, because the saving in lighting energy is generally much greater than any increase in heating energy.

Care should also be taken to ensure rooflight areas are not so large that they create a potential for solar overheating which may result in increased cooling loads.

Independent research by the De Montfort University’s Institute of Energy and Sustainable Development proves conclusively that compliant rooflights can save energy in many applications, and generally speaking, the greater the rooflight area the greater the potential savings. This is reflected in Building Regulations, which include limits on overall energy use, based on calculations which reflect the benefits that increased areas of rooflights can offer. Nonetheless, whilst rooflight areas and light transmission remain the prime consideration, thermal insulation of rooflights is an important secondary consideration, and limiting U-values for rooflights are also included within Building Regulations Generally, the better insulated the rooflight the better, although there is a law of diminishing returns. In some cases it may even be counterproductive to pursue very low values: if, for example, an excellent U-value is achieved by adding more and more layers of glazing, each additional layer reduces overall light transmission

28

Requirements of The Building Regulations

“In broad terms, the lower the U-value of a building’s overall fabric, the less energy is required to maintain comfortable conditions inside the building. ”

For all non-domestic applications, the worst acceptable standard for the thermal performance (U-value) of rooflights in new build work is currently stated as 2.2 W/m²K. For refurbishment or domestic applications, this figure is reduced to 1.8 W/m²K.

U-values for flat or ‘in-plane’ rooflights As the U-value is calculated by dividing the heat loss through the rooflight by its area, this is straightforward for flat, ‘in-plane’ rooflights, the type most frequently installed on metal or fibre cement roofs on factories, warehouses and large retail ‘sheds’. Therefore, manufacturers’ quoted figures can generally be used to form the basis of building calculations without further consideration.

U-values for ‘out-of plane’ rooflights and roof windows Many rooflights are ‘out-of-plane’ designs that sit proud of the plane of the roof (typically with glazing frames which may be mounted on upstands or kerbs). These include modular dome or pyramid rooflights, continuous barrel vaults, and glazing bar systems.

Furthermore, rooflights may be mounted onto upstands designed and supplied by others, which can effectively be considered as part of the roof, or some rooflights (particularly individual dome and pyramid modular

www.daylightingmag.co.uk

ROOFLIGHTS & SUSTAINABILITY Building Regulations state that the worst acceptable U-values for rooflights are based on the developed area of the rooflight (not the area of the roof aperture, which is the true U-value).

This is termed the Ud-value, and can be calculated for either a rooflight alone, or for a rooflight-and-kerb assembly.

rooflights) can be supplied as an assembly with a pre-manufactured kerb matched to the rooflight itself.

Building Regulations state that the worst acceptable U-values for rooflights are based on the developed area of the rooflight (not the area of the roof aperture, which is the true U-value). This is termed the Ud-value, and can be calculated for either a rooflight alone, or for a rooflight-andkerb assembly.

Ud-values: the correct values for checking against limiting values in The Building Regulations The Ud-value is calculated from the developed area of the rooflight. Where a rooflight-and-kerb assembly is being supplied, the rooflight supplier should be able to quote this value both for the rooflight only, AND for the entire assembly. To ensure Building

www.daylightingmag.co.uk

Regulations compliance, both of these values must achieve the worst acceptable standard of 2.2 W/m²K for refurbishment or domestic applications, or 1.8 W/m²K for domestic applications.

It is not acceptable to use an assembly of a rooflight with poorer thermal performance (such as double skin rooflights) on a kerb simply because the Ud-value for the rooflight-and-kerb assembly is better than the limiting values in the Building Regulations, unless the Ud-value for the rooflight alone also meets the limiting values.

NARM has published a number of technical documents covering the subject of rooflights and energy saving, which provide detailed information for specifiers. These can be downloaded free of charge from the NARM website. www.narm.org.uk

GRP rooflights: the sustainable solution Appropriately chosen GRP industrial rooflights can play a significant role in enhancing the sustainability of both new build and refurbishment projects, explains William McDowell of Hambleside Danelaw.

Appropriately chosen GRP industrial rooflights can play a significant role in enhancing the sustainability of both new build and refurbishment projects.

The sustainability benefit of rooflights within industrial buildings is commonly acknowledged: natural daylight reduces the need for supplementary artificial light. But GRP rooflights

30

can bring much more.

With latest developments, rooflights can now make a quantifiable points contribution towards BREEAM ratings.

Zenon GRP rooflights are the first to attain an independently verified Environmental Product Declaration (EPD) from the Building Research Establishment (BRE). The EPD means

www.daylightingmag.co.uk

ROOFLIGHTS & SUSTAINABILITY that inclusion of Zenon rooflights within a scheme can add 1.5points towards BREEAM accreditation under the Materials (Mat 02) category.

That tangible contribution is irrespective of any further contribution the rooflights may bring in the Energy and Health & Wellbeing categories.

Remember, Materials, Energy and Health & Wellbeing are the three most heavily weighted categories for BREEAM. Under Energy, rooflights contribute by reducing the need for artificial light: a rooflight allows up to three times more daylight into a building than the equivalent sized wall lights- and thermal performance: modern, double skin rooflights can attain a U value as low as 0.9W/m2K. Under Health & Wellbeing, rooflights are proven in numerous studies to improve occupant performance.

According to the Chartered Institute of Building (CIOB), 70% of the buildings currently standing will still be here in 2050. The opportunity therefore lies as much in retrofitting and upgrading existing building stock, which often feature old, thermally inefficient singleglazed rooflights.

core offers enhanced light transmission and lower embodied carbon than traditional rooflight insulating materials; it is manufactured from cellulose acetate that is compostable at the end of its life. Zenon GRP rooflights do not emit any chemicals once installed, so are safe to use with grey water systems, and in green roof schemes.

So in the battle to find sustainable strategies, look up to the roof, and make the most of a ‘hole’ in it. Full details of Hambleside Danelaw’s rooflight sustainable solutions can be found at: www.hambleside-danelaw.co.uk/ zenon-rooflights/

To optimise the role of rooflights within a sustainable project, there is potential to increase the ratio of rooflights: metal roof. Historically, the perception was 10% rooflights was optimal. However, independent research commissioned by the National Association of Rooflight Manufacturers (NARM) indicates that between 15-20% can reduce emissions by 28.7kgCO2/m2/yr.

Developments in rooflight technology have advanced the sustainability benefits. Zenon Evolution GRP sheet features an innovative reinforcement that gives a stronger substrate that is lighter in weight and has up to 40% less embodied carbon than traditional GRP rooflight sheeting. Zenon Insulator

technologies. As corporate social responsibility is a cornerstone of the business strategy, driving the inclusion of energy efficient design and sustainability into the construction of the new ARK warehouse was essential. The project successfully achieved LEED gold certification for incorporating sustainable and innovative practices to limit waste and minimise the carbon footprint.

www.daylightingmag.co.uk

CASE STUDY Astellas approached Kingspan Light + Air with a unique proposal for daylighting. Despite wanting to make the most of natural light to help to reduce energy consumption and reap the health and safety benefits of daylight for workers, it became apparent that solar heat gain needed to be controlled to protect the products manufactured at the facility.

“The project successfully achieved LEED gold certification for incorporating sustainable and innovative practices to limit waste and minimise the carbon footprint”.

Working from the design stage, Kingspan Light + Air provided a detailed technical support using building information modelling to showcase the potential and effectiveness of rooflights in regard to energy efficiency. Following an in-depth review of the proposal, Kingspan Day-Lite Kapture rooflights were installed to maximise the amount of useful daylight in the warehouse, whilst minimising demand for artificial lighting.

Kingspan Light + Air designed a bespoke solution to satisfy the requirements of Astellas. The tripleglazed rooflight used specially designed polycarbonate layers to maximise light transmission and climate control was also addressed – ensuring that solar heat gain was limited to ensure manufacturing products would not be compromised as a result of the additional light source.

The unique and technical requirements of Astellas Pharma and the seamless and bespoke design and installation completed by Kingspan Light + Air is testament to Kingspan’s commitment to providing efficient daylighting solutions that reflect the clients’ needs. Kingspan Light + Air’s ability to design and create unique solutions to satisfy all specifications demonstrates its dedication to deliver healthy, comfortable and efficient environments in a wide range of applications. www.kingspanlightandair.co.uk

Crossrail Place, Canary Wharf, London Foster + Partners’ design for this building is characterised by a landscaped, sheltered public park on the roof, accessible from ground level by connecting bridges.

The design of the lattice itself is a fusion of architecture and engineering. Despite the smooth curve of the enclosure, there are only four curved timber beams in the whole structure. To seamlessly connect the straight beams, which rotate successively along the diagonals, the design team developed an innovative system of steel nodes Between the beams are ETFE plastic cushions, which are filled with air and lighter than glass. These highly insulating air cushions create a comfortable environment for people to enjoy the gardens all year round, as well as providing a favourable microclimate for some of the plants, which include some of the species that first entered Britain through the historic docks.
