The Ultimate Guide to External Solar Shading Solutions in the UK

Introduction

The increasing importance of energy-efficient homes and workplaces in the UK is led by an amalgamation of economic, environmental, and social factors.
The energy crisis and cost of living increase, climate change, global warming and stricter building regulations including Part L of the Building Regulations in the UK (England and Wales) are all having an impact on the future of housing and 

workplace buildings with existing buildings also potentially facing the prospect of being subject to tighter scrutiny.

More public awareness of what is required for comfortable living and a productive working environment and subsequently the demand for better quality buildings is driving the need for further innovation and the employment of sustainable methods of climate control, including solar shading solutions.

What are the key reasons why energy efficiency has become a priority in the UK?

Solar shading solutions play a vital role in the UK’s sustainable building design by focusing on a number of essential elements, including lowering energy consumption, improving thermal comfort, and enhancing architectural aesthetics.

Listed below are leading reasons why energy efficiency has become a priority in the UK:

• Energy Crisis: The need to preserve resources and invest in renewable energy is vital to reduce the UK’s carbon footprint but is also a key factor in tackling the energy crisis that is crippling households and businesses in the UK. Those looking to buy or rent property may be swayed by the prospect of lower energy bills.   
• Climate Change and Global Warming: Global temperature rises, and climate change are having an impact on weather around the UK – becoming more erratic and extreme. The need to overcome these challenges whilst limiting further impact on the environment is key.
• The Net Zero Strategy: In 2021 the UK government set out a path to net zero in a landmark strategy intending to deliver on its commitment to reach net zero emissions by 2050. The strategy promised to secure 440,000 jobs and unlock £90 billion in investment in 2030 on the UK’s path to ending its contribution to climate change. It would include a transition to clean energy and green technology – lowering reliance on fossil fuels by investing in sustainable clean energy in the UK, reducing the risk of high and volatile prices in the future, and strengthening the country’s energy security. The plan would support the UK in gaining a competitive edge in the latest low carbon technologies – from heat pumps to electric vehicles – and in developing the country’s thriving green industries in its industrial heartlands – from carbon capture to hydrogen. The resulting pioneering ideas and technologies would help to decarbonise homes, industries, land, and power.
• Connection with the outside: Large expanses of glazing are favoured by UK building designers because they afford occupants of buildings the opportunity to connect with the environment around them – allowing natural daylight to flood into a room and providing panoramic views. However, glass is a poor insulator and allows heat to pass through more easily, so, this desirable feature of modern UK living has the effect of acting like a greenhouse., creating an uncomfortable environment for occupants and generating a need for means of energy efficient thermal comfort control.
• High-rise living: This may come as a bit of a surprise but over the past few years the UK has become one of the most nature depleted countries in the world, facing significant challenges relating to habitat loss, biodiversity decline, and environmental degradation, primarily due to urbanisation, animal agriculture, and historical industrial activities. With pressure on green belt land and the need to preserve the natural beauty of the UK, developers are building higher. Taller buildings have more surface area and can be oriented in a way that exposes them to direct sunlight for longer periods. Depending on their orientation relative to the sun’s path, specific sides of a high-rise building may receive more direct sunlight, leading to increased solar heat gain resulting in the need to employ energy efficiency measures to ensure thermal comfort of occupants.
• Building Regulations: In an attempt to shake-up of the UK’s building industry as of September 2021, several energy efficiency building regulations and standards were implemented to promote sustainable and energy-efficient construction, including:
• Part L of the Building Regulations (England): Part L of the Building Regulations in England highlights the need to conserve fuel and power in buildings. It sets obligations for energy efficiency, including standards for insulation, heating systems, and lighting. The government regularly updates Part L to tighten energy efficiency standards and promote sustainable building practices.
• The Future Homes Standard (England): The Future Homes Standard is a regulation that aims to improve the energy efficiency of new homes in England. It is expected to require higher levels of insulation and more efficient heating systems, as well as a focus on low-carbon technologies.
• The Future Buildings Standard (England): The Future Buildings Standard aims to improve the energy efficiency of non-domestic buildings. It sets higher energy performance requirements for commercial and industrial buildings, with a focus on reducing greenhouse gas emissions.
• The Building Regulations (Scotland): In Scotland, the Building Regulations include Section 6, which pinpoints energy efficiency and conservation as a priority. These regulations set standards for insulation, heating systems, and energy performance for new, as well as existing buildings.
• The Building Regulations (Wales): In Wales, Part L of the Building Regulations spotlights energy efficiency and conservation. These regulations set standards for energy performance, insulation, and heating systems in both residential and non-residential buildings.
• Energy Performance Certificates (EPCs): EPCs are required for both residential and commercial properties in the UK. They provide information about a building’s energy efficiency and recommend procedures to improve it. EPC ratings are used for compliance with various regulations and standards.
• Minimum Energy Efficiency Standards (MEES): MEES regulations apply to residential and commercial properties in England and Wales. They set minimum energy efficiency standards for rental properties, making it unlawful to rent out properties that fall below a specified EPC rating.
• Renewable Energy Standards: In addition to energy efficiency regulations, there are various standards and incentives to promote the use of renewable energy sources, such as solar panels and heat pumps, in buildings. These standards may vary from region to region.

At the time of publication, amongst other policies, tighter building regulations have been implemented in the UK in an attempt to meet net zero carbon targets and promising to align with the construction industry of more progressive countries. Although reaching net zero by 2050 was set in law, sadly, the current government is considering reneging on some of those promises. It is unclear exactly which commitments will be affected but the fact remains, more energy efficient buildings are required and existing buildings in need of updating, as they account for 44% of the overall energy consumption in the UK which includes artificial heating, cooling, and lighting.   

Understanding Solar Shading

What is solar shading and why is it crucial?

Solar shading refers to a set of architectural or engineering techniques and devices designed to control the amount of sunlight and solar heat that enters a building or outdoor space. The primary objective of solar shading is to effectively manage solar radiation, providing benefits such as a reduction in energy consumption, improving thermal comfort, and enhancing the overall functionality of a building.

More details of why solar shading solutions are crucial are discussed further on in this article which includes:

• Solar shading’s ability to improve energy efficiency and reduce energy bills.
• Solar shading solutions contribute to thermal comfort.
• Solar shading systems optimise daylight management/harvesting.
• Solar shading guards against harmful UV
• Solar shading can act as privacy screening and security.
• Solar shading’s versatility for architectural aesthetics
• Solar shading’s contribution to environmental sustainability

The science behind it: How do solar shading solutions reduce solar heat gain and lower energy costs?

The science behind solar shading is multidisciplinary, encompassing physics, materials science, architecture, and engineering – put simply – the principles of solar radiation, heat transfer, and the behaviour of light as it interacts with various building materials such as glass. Solar shading solutions are designed based on these scientific principles to optimise energy efficiency, reduce solar heat gain, and enhance thermal comfort within buildings.

The following lists key scientific properties of solar shading:

• Solar Radiation: Solar shading is principally concerned with managing solar radiation, which includes both visible light and invisible forms of electromagnetic radiation, such as infrared and ultraviolet radiation (UV), emitted by the sun.
• Solar Heat Gain: Solar radiation transfers energy in the form of heat. When solar radiation enters a building through windows and other exposed or open areas, it can contribute to solar heat gain, causing indoor temperatures to rise.
• Heat Transfer: The science of heat transfer, particularly conduction, convection, and radiation, plays a vital role in solar shading. Solar shading solutions aim to reduce heat transfer by blocking or reflecting solar radiation.
• Absorption, Transmission, and Reflection: Building materials have properties related to how they interact with solar radiation. Some materials absorb solar radiation (converting it into heat), some transmit it (allowing it to pass through), and some reflect it (redirecting it away from the building or space).
• Shading Coefficients: Shading coefficients are values that indicate the effectiveness of a solar shading system in reducing solar heat gain. They are used to calculate how much solar radiation is transmitted, absorbed, or reflected by the shading system.
• Solar Geometry: The angle at which solar radiation strikes a building’s surfaces varies throughout the day and across seasons due to the Earth’s rotation and axial tilt. Understanding solar geometry helps in the design of solar shading solutions that effectively block or diffuse sunlight at different times of the day and year.
• Daylighting: Solar shading solutions are usually designed to optimise natural daylight while minimising solar heat gain. The science of daylighting involves controlling the amount and distribution of natural light within a space to reduce the need for artificial lighting and  the enhance visual comfort of occupants.
• Psychrometrics: Psychrometrics is the study of the properties of air and how it interacts with temperature, humidity, and other factors. Solar shading solutions can impact indoor air temperature and humidity levels, affecting thermal comfort.
• Computational Modelling: Computational tools and simulations, such as energy modelling and daylighting analysis, use mathematical equations and algorithms to predict the performance of solar shading systems in specific building settings. These tools assist architects and engineers in designing optimum shading solutions.
• Smart Technologies: Advancements in sensors, automation, and control systems have led to the development of smart solar shading solutions that can adjust shading levels based on real-time data, such as sunlight concentration and indoor temperature.

What are the benefits of solar shading solutions?

Solar shading solutions offer a wide range of benefits for buildings and outdoor spaces – encompassing energy efficiency, thermal comfort, environmental sustainability, and more.

Listed below are some of the advantages of using solar shading solutions:

By blocking or diffusing direct sunlight, it prevents excessive solar heat gain, which can lead to increased cooling loads during hot weather. This, in turn, reduces the need for artificial and mechanical methods of climate control such as fans and air conditioning, resulting in lower energy bills and decreased greenhouse gas emissions.
• Reducing The Urban Heat Island Effect: Solar shading solutions can play a significant role in mitigating the urban heat island (UHI) effect. The UHI effect refers to the increasedtemperature in urban areas such as London, for example, compared to surrounding rural areas. This phenomenon occurs due to human activities, modification of land surfaces, heat generated by buildings and vehicles, and limited green spaces. Solar shading helps combat the UHI effect in several ways helping to maintain a more thermally comfortable building and reducing the energy costs and consumption needed for cooling.
• Thermal Comfort: Solar shading solutions contribute to improved thermal comfort inside buildings. It helps maintain stable indoor temperatures by preventing overheating during sunny days and minimising heat loss during colder periods. This creates a more pleasant and consistent environment for occupants, improving overall comfort and reducing the need for temperature control systems.
• Daylight Management/Harvesting: Solar shading can be used to optimise natural daylight. By controlling the amount of sunlight entering a space, it can reduce the reliance on artificial lighting during daylight hours. Not only saving energy but also enhancing the visual comfort and well-being of occupants by providing a balanced and glare-free lighting environment.
• UV Protection: Solar shading solutions can block harmful ultraviolet (UV) radiation from the sun. This protection helps preserve interior furnishings, materials, and artwork, preventing them from fading or deteriorating due to prolonged sun exposure.
• Privacy Screening and Security: Solar shading solutions can improve privacy within a building or outdoor space, especially in urban locations or where overlooked by other buildings. It can prevent outsiders from easily seeing into a building while still allowing those inside to maintain a connection to the outside world. Additionally, some shading solutions can serve as security features by providing an additional layer of protection against break-ins or vandalism.
• Architectural Aesthetics: Solar shading solutions can be integrated seamlessly into the architectural design of a building, adding an aesthetic feature to the structure. They come in a variety of styles, materials, and colours, allowing architects and designers to choose options that complement the building’s overall appearance and contribute to its visual appeal.

They are often made of wood or metal and operated manually or with motorised systems. Shutters are popular for shading, privacy and security purposes and most commonly found on residential properties, public houses, and shops.
• Solar Control Glass: While not a solar shading solution in the traditional sense, solar control glass has special coatings that reduce the amount of solar radiation and heat that enters a building or space. It is used in windows and facades to improve energy efficiency and can be used on a variety of buildings but tends be used where there are large expanses of glazing and where solar gain can be a major issue.
• Green Roofs and Living Walls: Again, not traditional shading solutions, green roofs and living walls – or green walls – can provide natural shading by covering parts of a building with vegetation. These features offer insulation benefits and contribute to environmental sustainability. It’s worth noting that solar shading solutions involving plantings like trellises or green walls, can create additional habitats for birds and insects. These structures offer shelter, nesting opportunities, and places to perch, enhancing the local ecosystem. Living walls are increasing in popularity and valued for their environmental and wellbeing benefits, becoming a feature of galleries and museums, apartment buildings, shopping complexes, boutique hotels and spas as well as restaurants, airports and office buildings. Green roofs are becoming more commonplace on carbon neutral new builds and can be found on sustainable housing, visitor centres and attractions including Jodrell Bank’s First Light Pavilion
• Exterior Roller Shutters: Roller shutters are metal panels that can be rolled down to completely cover windows or openings. They offer shading, security, and noise reduction benefits. Motorised versions are available for convenience.
• Pergolas and Shade Structures: Pergolas and shade structures are freestanding or attached outdoor structures with open roofs that provide partial shading. They are often used in gardens, patios, and outdoor seating areas.
• Tensile Fabric Structures: Tensile fabric structures are lightweight, flexible shading solutions that use fabric membranes stretched over a rigid frame. They are often used in outdoor spaces, such as car parks and outside eating areas, to provide shade.

  

The choice of external solar shading solution depends on circumstances such as the building’s design, orientation, budget, and specific shading requirements. Many of these solutions can be customised to fit the aesthetics and functional needs of a particular project in the UK’s variable and unpredictable climate.

Sherborne Girls’ Arts Centre’ Excelling with External Solar Shading

Nestled within the picturesque campus of Sherborne Girls School in Dorset, The Merritt Centre stands as a beacon of artistic inspiration and creative exploration. This state-of-the-art art facility, often referred to as simply “The Merritt,” – named in memory of Gwendoline Merritt, a former member of staff who left her entire estate to the school when she passed away in 2014 – has been at the heart of Sherborne Girls’ commitment to fostering creativity, innovation, and artistic excellence.

Following the two-year construction project, the new arts centre building – based at the heart of the Sherborne Girls campus in Dorset – was the final installment in the school’s growing for the future’ development.

The plan included a transformational new performing arts centre which comprises of a new music school, recital hall, two foyers, practice rooms, a recording studio, exhibition space, multi-functional social areas, café, and new drama school.

Regarded as an invaluable addition to the overall development and embraced by the local and wider community – it was made possible thanks to a significant £2.5m fundraising appeal.

The new building would be located towards the centre of the school grounds, with the existing school buildings on one side and playing fields to the other. The environmental design of the building exploits this setting by using passive measures to connect the internal spaces to the outdoors via large windows and acoustically attenuated natural ventilators. This provides generous daylighting throughout the building and fresh air without unnecessary noise transfer.

Within the main 500-seat concert hall, where more strict acoustic conditions are required and large audiences are expected during the height of summer, an almost silent mechanical ventilation system would be provided to condition the space that the audience and performers will occupy. This system is demand-controlled and incorporates energy recovery to minimise the energy wasted to the outside of the building.

Elsewhere energy demand in the building is minimised: good air tightness and thermal insulation will reduce the heating and cooling demand; intelligently controlled, low energy LED lighting would be installed throughout the building; and hot water generated locally as required to reduce standing losses within the system.

Further heating and cooling of the building are provided from a ground source heat pump. This takes advantage of the availability of adjacent playing fields where numerous boreholes have been installed to extract heat from the ground, significantly reducing the CO_2eq impact of the building.

Working alongside Morgan Sindall, the Solinear team was tasked with providing an effective solar shading solution for the new £11 million arts centre – from design through to installation of the aluminium louvres over glazed areas and reception entrance.

Once manufactured, the solar shading panels were destined for the Sherborne Girls School campus in Dorset.

As the school is in a residential area on Bradford Road – the main road through the residential area – the schedule for deliveries and installation was strict with any delays reported to site managers and deliveries booked for specific time slots. If a slot was missed, then a new time slot would need to be booked that would cause the least disruption to the local area.

One of the 36 SMEs working on this phenomenal project, Solinear’s contribution to this magnificent new facility was a solar shading solution that would be functional – incorporating the building’s sustainable construction principles – whilst also enhancing the exterior of this contemporary, purpose-built arts centre.
The solar shading solution offered multifaceted benefits including:

• • a louvre system that complements the hue and architectural style of the façade elements as well as the simple yet dramatic concert hall roof.
  • The projecting solar shading allows for occupants of the building to have a completely uninterrupted view of the beautiful school grounds particularly the multi-use social spaces which have spectacular views across the playing fields, whilst protecting them and the interior space from punishing solar glare.
  • As a result of its Passivhaus climate control and thermal comfort benefits it also reduces the need for artificial or mechanical heating and cooling of the internal space thus helping to lower energy consumption and save money. In the face of ever-increasing energy bills, solar shading solutions are certainly a progressive approach to lowering the running cost of the building.
  • In a unique environment, such as this, where sound clarity is of the utmost importance, solar shading solutions offer a completely silent method of climate control.

Soon after completion, and before official opening, the centre began being used daily by both the school and local community and hosted the National Children’s Orchestra of Great Britain, Sherborne Abbey Music Festival and TEDxSherborne. As part of the school’s aim to support and fully engage with the wider Sherborne community, local schools and community organisations are able to book the venue,

Sherborne Girls celebrated the official opening with a spectacular concert featuring Dame Emma Kirkby, former pupil, and world-renowned soprano, performing alongside the school’s senior choir in an unforgettable event that truly showcased the recital hall’s magnificent acoustics. The opening concert was the highlight in a week-long series of creative, musical, and theatrical performances, many of which were open to the public and placed the students’ abundant creative talents firmly in the spotlight.

The social values of the The Merritt Centre include the following;

• 36 SMEs delivering 97% of project spend
• Project Value £6.22m
• Created £5.87m (94%) social value using social value bank calculator out of which:

• 32% businesses
• 33% government

It was, once again, a delight to work with Morgan Sindall…

Candice Taylor, Morgan Sindall Regional Supply Chain Coordinator (Construction South) stated:

“You will note how much social value you have helped provide on this project, we are committed to leaving a growing positive legacy across our region and your support in providing the feedback on the information we request for LM3, your apprenticeship commitments and diversity is essential if we are to capture the benefit being provided. Thank you to everyone who contributed, and we look forward to many future successful projects.”

Solar shading solutions address multiple important aspects of modern life, forming an integral element of contemporary and sustainable building design, construction, and operation. With multifaceted benefits, they offer UV protection, improve thermal comfort by regulating indoor temperatures and reducing glare, enhance architectural aesthetics by offering design flexibility and integration possibilities and help to reduce energy consumption by optimising daylighting and controlling heat gain thus decreasing the cooling load on heating, ventilation, and air conditioning (HVAC) systems.

It’s evident that with the increasing demand for environmentally conscious, energy efficient buildings in the UK, solar shading innovations are expected to become a standard feature of contemporary UK architecture and building design. These innovations not only enhance the overall performance of a building but also symbolise a substantial step forward in the pursuit of a greener and more sustainable future for the construction industry especially in light of recent news headlines suggesting that the government intends to dilute its own path to net zero,

Whilst some may welcome the U-turn and appreciate a more relaxed and complacent approach to environmental issues, many are concerned that the UK could find itself in an even more precarious situation in years to come. If buildings currently under construction or older buildings do not come anywhere near meeting the potential net zero targets of the future, the shortfall in building efficiency standards could cost billions to the UK economy along with inconvenience to businesses and households.

Some older Passivhaus methods of energy efficiency may still be beneficial in reducing the carbon footprint of a building but by modern standards they could fall short in offering the protection required in today’s climate and that of the future, Contemporary solar shading solutions have proven to be so important in the battle to help create a better environment internally as well as externally of the built milieu that they have advanced greatly from their ancient rudimentary designs. Solar shading is the subject of constant change driven by continuous advancements in materials and technologies including the integration of photovoltaic capabilities that generate electricity while providing shade; sun-tracking programs, digital fabrication and 3D printing, motorised and automated systems offering flexibility and removing the need for human intervention alongside the incorporation of environmentally-friendly materials

Aside from the disruption and financial cost of upgrading a building that has either very minimal or no energy efficiency methods in place, environmental impact is even more of a concern as global temperatures rise and extreme weather becomes commonplace. The UK’s weather is becoming more unpredictable, and the past few years have been the hottest on record. Amber weather warnings have increased, and even red warnings for extreme heat have been issued warning of potential risk to life with advice to stay indoors.
However, some internal spaces of buildings can be hotter than Death Valley – considered one of the hottest places on Earth. Studies have shown that some buildings in London, for example, can reach temperatures upwards of 45°C as a result of solar heat gain making living conditions extremely uncomfortable and creating an unproductive working environment.

Whilst mechanical methods of providing thermal comfort, such as fans, are able to offer some relief, it is far more beneficial for the environment, rate payers and building occupants if this can be achieved through unobtrusive thermal comfort control methods.

As the population of the UK continues to rise, prime building land is in high demand and green belt land is at risk – buildings jostle with each other for space, standing window to window – society becomes more compacted and concentrated in towns and cities all over the UK, privacy may be compromised. Solar shading solutions also provide privacy and security benefits – shielding occupants and objects from onlookers and potentially unwanted attention.

With the evidential benefits presented, it’s clear that solar shading solutions have been elevated from a building’s postscript to an intelligent, sustainable, visually impressive and necessary architectural component. Whether a basic, fixed structure, more sophisticated arrangement or complex motorised system, solar shading should be at the forefront of UK building design and construction for the welfare of people and planet.
