7. Chicago Cube, Chicago, Residential Complex, Kyiv, Ukraine Over the past two centuries, our cities have been expanding at an incredible pace. More buildings, offices, shopping centers, more concrete and asphalt. Development was the priority, while ecology was, at best, a secondary concern. more sustainable. I am pleased to note that a significant portion of these positive changes is happening in the field of architecture. aware of all the technical intricacies of glass architecture, I must disappoint you: this is only in theory. Today, let’s discuss why glass is not always eco-friendly and what can be done to change the situation. One of these changes includes the development of glass architecture, which is becoming increasingly popular in our cities. The promotion of eco-friendly materials like glass and the growing prevalence of glass architecture could have a positive impact on the However, as someone who is well Getting Rid of Metal It may sound strange, but glass architecture often is not truly made of glass. Let me explain. One of the important characteristics of a glass unit is its ability to resist wind loads. In a typical glass unit, this function Fortunately, in the 21st century, the situation has significantly improved. Humanity has become much more responsible towards nature and its resources and is constantly working to make every aspect of our lives environment. 5 WFM | SEPTEMBER-OCTOBER 2023

It is five times higher than that of steel and over 200 times higher than that of glass. By eliminating aluminium, we not only remove tons of expensive material and a large amount of waste from the process but also eliminate the main cause of heat loss and low energy efficiency. Otherwise, we would have to compensate for all of this with the cost of electricity – heating or cooling the building, depending on Now let’s calculate how many resources we would expend over the entire lifespan of the façade. No complex calculations are needed to understand that the sum is colossal. the season. UNIT City Office, Kyiv, Ukraine is assigned to the first layer of glass. This forces manufacturers to increase the thickness of the first layer of glass significantly, making the glass unit quite heavy. To keep it on the façade, a large number of supports and ridges are required, which spoil the overall aesthetics of the façade, taking away its lightness and also encroaching on interior space. frame. This method of bonding glass layers allows the glass unit to withstand much greater loads since all layers contribute to its resistance. In addition, frameless glazing solutions allow for significant optimisation of time. Façade installation using frameless glazing can begin as soon as at least one floor is ready, rather than waiting for the entire building to be completed. And finally, let’s talk about the obvious – money. Aluminium, while not the most expensive of metals, will see a significant increase in demand in the coming years. Consequently, the market will react with a price increase. Goldman Sachs predicts that by 2025, the price of aluminium will rise to $3500 per ton. construction technology The glass units are connected to each other with metal fasteners, which are screwed directly into the composite frame and then secured to the structural elements of the building. This way, we achieve an aesthetic and seamless glass façade where each element is essentially self-supporting. We were searching for a solution to make architecture aesthetic and environmentally friendly and improve its energy efficiency. And we found it. It is the technology of frameless glazing based on insulated glass units with higher stiffness (IGUHSs). Such a glass unit has an important structural feature: all glass layers are rigidly bonded together, and the perimeter is additionally reinforced with a composite more Saving Resources As an engineer, it amazes me that manufacturers continue to use aluminium extensively. First, the production of this metal requires a significant amount of resources. At a minimum, it takes 14 MWh per ton. Secondly, it is highly toxic. Only indirect emissions from electricity I am confident that in the pursuit of creating a comfortable, safe, and environmentally environment, every small step matters. friendly 6 WFM | SEPTEMBER-OCTOBER 2023

13. Solar façades are the cheapest façade of all façades! This is not a myth but an undervalued reality for the future of sustainable façade design. Solar façades deliver solar energy to progressively pay down its own cost while all other façade materials (including paint and plaster) will continue to incur additional costs throughout its life cycle period. It follows therefore that a solar façade with its active financial gain is an asset while all other façades should then be classified as a long- term liability. Therefore, in reality, solar façades which may appear to be more expensive initially, will ultimately emerge as the cheapest façade ever. So, will this new realisation be sufficient enough to move the needle for the industry to adopt solar façades as a new asset-class building material? I think the answer is quite obvious but the truth is there are still many legacy problems that need to be explained and practically proven before they can be accepted as mainstream solar architecture. Problem statement: A sense of colors and aesthetic Until the advent of the innovative colored PV, the traditional patchy black PV was also a big pushback to the deployment of solar façades. solar due to the potential power loss from the reduced irradiance of the vertical surface. So, let me address some of these problems as the way forward. Singapore lacks land space and rooftop space horizontal solar. But, we have a huge amount of vertical space on the buildings to mount BAPV (wall mounted PV) or BIPV (wall- integrated PV). Hence, the industry is naturally inclined to believe that vertical solar façade is unlikely to deliver any appreciable payback, much less an ROI. So, instead of accepting this as a matter of physic-driven fact, it has evolved into a stubborn legacy problem impeding the deployment of vertical solar. for mounting However, with the introduction of attractive colors to the PV panels, solar architecture may be pushed to take center stage, especially with regards to architectural aesthetics as well as addressing the urban heat island (UHI) effect, especially The Vertical Factor The industry has been quite skeptical about installing vertical 11 WFM | SEPTEMBER-OCTOBER 2023

Problem Statement: Financial Pragmatism Obsession With ROI Undue ROI obsessions, driven by financial pragmatism have caused many cancellations. This is due no less to the lack of information and qualified data which in turn lead to misunderstanding and misrepresentation to the decision makers. The real-world data suggest that PSA’s total financial gain from its solar installation is projected to exceed several times its original cost, with IRR exceeding 1O%. and Undue About PSA Tuas Test-Bedding In the case of PSA Tuas, the solar façade is able to deliver sufficient solar energy to offset the delta cost or the differential cost between aluminium cladding with solar cladding in a very short time. solar project Although this financial projection is rather impressive, it does not follow therefore that all other solar façades will deliver the same result due to other variables including For ease of reference, I shall refer to this as the primary ROI. The architecture also contribute to the lack of engagement and information flow across the industry. small number players of solar may While the primary ROI of PSA Tuas was originally projected to be much longer the reduced primary ROI of less than 3 years is a pleasant surprise representing an impressive push factor moving forward. Solution: Government Lead Test Bedding Project It is for this reason that our Singapore Government has funded a project at PSA Tuas to serve as national test-bedding for BAPV solar façade installation. The impressive result is of course collated with favourable real- world data-driven in part by improvements in colored solar technology. After the primary ROI, the solar façades would continue to produce solar energy beyond its service The real-world data collected from is test bed is expected to form a 12 WFM | SEPTEMBER-OCTOBER 2023

This will provide them with an added impetus to exploit the unprecedented opportunity in order to enjoy the full financial gain from the cheapest façade ever. The may vary according to the prevailing carbon tax rate, but as we approach our committed datelines and ever-elusive low carbon targets, it is likely that the amount will escalate further as a punitive measure to drive urgent climate action. carbon tax amount PSA Tuas shall however serve as a good validation benchmark and study model from which an educated understanding of the workings of vertical solar will inspire the solar façades of the future. Environmental Carbon Reduction and Low Carbon Tax Financial benefits aside, solar façade is also known is deliver the highest carbon reduction ever. A solar façade is 60 times more efficient in reducing carbon emissions than a green wall. Green walls will produce oxygen to clean the environment, which is great for air pollution control. It is however not necessarily the best option to reduce carbon tax due to its relatively low carbon reduction index. Other material options are also not particularly impressive in turn of measurable carbon reduction. Factor: High It deploying vertical solar façades can be both aprofitable and a sustainable endeavour, in spite of its apparent disadvantage with vertical solar irradiance. re-affirms our belief that Should that happen in the future, then it will translate into a big opportunity cost for those who were not astute enough to install solar façades in the first instance. for example Solar façade is still in a rather nascent state at the moment since some decision makers are mistakenly led to believe that it is a only “good to have” option. It should also be sufficient ground to debunk the legacy notion that vertical solar will never achieve an ROI, though this ROI may vary according to different projects. Given the high potential for financial and benefits of solar façades as discussed in this article, it is not inconceivable that solar architecture will surely be brought into the spotlight as mainstream architecture of the future. It also reinforces our earliest assertion that solar façade is indeed the cheapest façade material ever, since no other material is expected to pay for its own cost. environmental It is envisaged that PSA Tuas has the potential to save a further $500,000 in carbon tax avoidance from its 30-year service life of solar façade installation. In spite of the favourable study, it may still be necessary for decision- makers with undue ROI obsession to modify their expectation to focus After all, which building does not need an energy-producing solar façade as a financial asset. 13 WFM | SEPTEMBER-OCTOBER 2023

Studies reveal that inadequate ventilation can lead to Sick Building Syndrome (SBS), affecting up to 30% of new and renovated buildings worldwide. SBS is responsible for a range of health issues, from respiratory discomfort to fatigue, and it underscores the importance of effective ventilation systems. Scientific insights further highlight the benefits of balanced ventilation, such as Mechanical Ventilation with Heat Recovery (MVHR), which can reduce heating and cooling energy demands by up to 60%. Research also emphasises In the United Kingdom, where sustainability standards rigorously upheld, stringent Building Regulations mandate U-value requirements to ensure that structures are well-insulated. For instance, a comprehensive study conducted by the National Institute of Building Sciences (NIBS) rigorously examined the impact of U-values on energy consumption in commercial office buildings by analysing a range of U-values for windows and insulation materials used in the construction industry. It revealed a clear correlation between lower U-values and reduced energy consumption: windows U-values below 1.0 W/m²·K were found to result in up to 30% lower heating and cooling costs compared are and building specific commonly with Figure 3 U-value- Heat flow through a thick and a thin building wall 18 WFM | SEPTEMBER-OCTOBER 2023

26. Cover Story Shaping the Future of Architecture: The Transformative Role of Glass Façades Glass has become a transformative material in modern architecture, offering a multitude of advantages that go far beyond its aesthetic appeal. As a favoured façade material, it allows for sleek and versatile designs, maximises natural light penetration, and fosters a strong connection with the surrounding environment. Moreover, innovations like low- emissivity coatings have significantly contributed to the energy efficiency of glass, making it a sustainable choice for modern buildings. In regions with abundant sunlight, such as the Gulf, glass façades play a crucial role in optimising energy savings by reducing the need for artificial lighting and cooling. One of the most vulnerable aspects of building design is the façade. Because the majority of the populace is unaware of the material’s performance, they frequently misunderstand the importance of façade design, particularly in limiting or spreading fire spread. Fire safety has traditionally been overlooked in favour of beauty, energy efficiency, cost, and other factors. However, in light of current market trends, this has progressed beyond only the aesthetic aspect and now plays a larger role in light conveyance, acoustical execution, and efficacy. solar control, make it essential to consider local climate and environmental conditions. In this era of evolving technology and sustainability goals, architects and designers are increasingly focused on specifying the right glass for façades.

Glass coatings are essential for enhancing façade performance. Reflective coatings help in reflecting solar radiation, reducing heat gain. Low-E coatings minimise the amount of ultraviolet and infrared light that can pass through glass without compromising light transmittance. These coatings are pivotal in the Gulf to manage the intense solar conditions, explains Fadi. Kareem believes that the type of glass selected has a significant contribution to façade isolation, U-value is the term used to describe thermal insulation, the lower the better. Single panels have the lowest U-value, insulating units which consist of 2 or more single panels separated by an air or gaseous spacing significantly reduce the U-value of the glazed unit, the air space acts as a thermal barrier, helping to keep the building warm in the winter and cool in the summer. Different Types of Glass Coatings and their Role in Enhancing the Performance of a Glass Façade Kachwala elaborates that each type of coating addresses specific aspects, combining functionality, aesthetics, and practicality to optimise the overall performance of the glass façade. Energy: Solar coatings, multi-functional Low-E coatings (single, double, or triple), play a pivotal role in controlling energy transfer, effectively minimising heat loss or gain. This enhances the overall energy efficiency of the building by reducing the need for excessive heating or cooling. Aesthetics: Tinted substrates and/or coloured reflective coatings, contribute to the visual appeal of the glass façade.

Thicker glass and insulation can help to reduce heat loss in the winter and heat gain in the summer, making the building more comfortable to live in. Additionally, insulation can help to reduce noise transmission from the outside world, making the building quieter. Effect of Glass Thickness and Insulation Affect a Building’s Thermal Performance and Comfort Levels “The thickness of glass and its insulation significantly influence a building’s thermal performance and comfort. Thicker glass tends to absorb more heat, impacting the internal and external temperature. The decision to increase glass thickness is often driven by safety considerations and wind load requirements. Additionally, incorporating insulation, such as Insulated Glass Units (IGUs), our ecoTHERM product plays a crucial role in enhancing thermal performance, contributing to improved comfort levels within the building”, Kachwala. The optimum glass thickness of your building will depend on several factors, including the climate, the orientation of the building, and of course your budget. Glass manufacturers now offer digital calculator tools that can be used to compute the U-value of a glass unit before it is implemented in a project. These tools are typically easy to use and provide reasonable results. s a great way to ensure that you are choosing the right glass for your project. by knowing the U-value of the glass, you can select a glass unit that will help you achieve your desired energy efficiency goals.

Glass maintenance to preserve their aesthetic and functional qualities. In regions with high sand and dust levels, like the Gulf, selecting glass with easy-to- clean coatings and robust sealing systems is essential for long-term durability. There are also new types of technologies that incorporate self-cleaning for the glazing, believes Fadi. façades require regular cleaning and Maintenance Requirements or Considerations for Long-Term Durability When Using Glass as a Façade Material Kachwala believes that regular maintenance is crucial for preserving the longevity and aesthetic appeal of a glass façade. Routine cleaning is essential to prevent the accumulation of dirt, ensuring the transparency of the glass. Simultaneously, it is imperative to inspect and maintain frames and sealants regularly, safeguarding against water maintaining structural integrity. This dual approach to cleaning and maintenance not only enhances the façade’s visual appeal but also contributes to its overall durability. To further fortify the structure, scheduling periodic professional inspections is recommended. These inspections serve to comprehensively assess the façade’s condition, identify potential issues, and implement preventive measures, ultimately contributing to the long-term resilience of the glass façade. Glass façades require periodic cleaning, especially in urban environments with higher pollutant levels. Inspection of sealants is important for catching leaks before damage occurs. Proper drainage, flashing, and waterproofing protect substrate materials long-term as well, suggests Kareem. infiltration and 30 WFM | SEPTEMBER-OCTOBER 2023

33. The Safety Aspects of Glass Façades, Including Concerns Related to Breakage and Impact Resistance Ensuring safety in our glass façades involves a dual strategy. On the ground floor, we utilise tempered glass, specifically our ecoSHIELD (Tempered) product, which is five times stronger than annealed glass, providing exceptional resistance to high-impact loads. Above 10 meters we usually recommend ecoFAÇADE (Heat Strengthened) because it will be breaking into smaller, safer pieces upon fracture. Adherence to local building codes and safety standards guides our glass selection process. Regular maintenance and inspections, prompt replacement of damaged glass panels, and emergency planning for high-traffic areas contribute to a secure and resilient glass façade. This comprehensive approach ensures safety without compromising on the aesthetic and functional aspects of our architectural design, says Kachwala. Safety laminated glass is crucial to prevent injuries due to breakage and to enhance impact resistance. Façade designs should also consider wind loads, especially in high-rise buildings in the Gulf, where high winds can pose significant challenges. Safety glass is important also for glass showers and especially important for glass balustrades, says Fadi. Image Courtesy - Future Architectural Glass Safety Aspects of Glass Façades • Thermal stress: When glass is exposed to a sudden temperature change, such as a fire or hot blast, it can expand and contract rapidly, causing it to break. Edge Hit: Glass edges are sensitive and the breakage pattern spreads massively when it is on the edge point Brittle nature: Glass is a brittle material, which means that it is strong under compression but weak under tension. This means that glass is more likely to break when it is subjected to a force that is trying to pull it apart, sometimes the breakage happens without an obvious reason. It may be a manufacturer defect or faulty installation. Some precautions that decrease the breakage possibility and increase safety measurements: Use tempered \/Heat Strengthened glass: Tempered glass is more impact-resistant than regular glass and is therefore a good choice for glass façades. Use laminated glass: Laminated glass is made up of two or more layers of glass bonded together with a PVB interlayer. This makes it more resistant to breakage and impact. Inspection and testing: Glass façades should be regularly inspected and tested to identify any damage or defects. • • • • • • - Kareem Kamel, Façade & Steel Structural Engineer 31 WFM | SEPTEMBER-OCTOBER 2023

Future Glass team understands the acoustic requirements of the building depending on the outside noise parameters and suggests suitable glazing combinations to achieve comfortable working / living spaces. Glass plays a pivotal role in acoustic insulation. Double or triple glazing with varied glass thickness and laminated glass can significantly reduce noise levels, essential in the bustling urban environments of the Gulf region, believes Fadi. The thickness of the glass is an important factor that can help to block sound waves from entering a building, as thicker glass is more effective at blocking sound waves. Typically, 6mm thick monolithic glass, has a lower STC value than 12mm thick, glass STC can reach 36Dbs, whether it’s single piece monolithic glass, laminated glass, or insulated glass, the thicker the total glass thickness, the better sound transmission loss. Using air spaces of different thicknesses in a double-pane or triple-pane glass unit can help to improve the acoustic performance of the glass, generally, the thicker the air space the more increase in sound transmission loss, says Kareem. The Future of Glass as a Façade Material Evolving in Response to Technological Advancements & Sustainability Goals The evolution of glass façades in the future will be marked by smart glass technologies, incorporating dynamic control for enhanced transparency and energy efficiency. Innovations in nanotechnology, recyclable Image Courtesy - Future Architectural Glass Role of Glass in Acoustic Insulation and Noise Reduction in Urban Environments Kachwala believes that double or triple glazing, combined with laminated glass, effectively reduces sound transmission. Well-sealed frames, soundproofing, and thicker glass impede sound waves, while acoustic films and coatings enhance sound absorption. Strategic placement of sound-resistant glass in high-noise areas ensures a quieter indoor environment. Enhanced acoustic interlayers from Kuraray or Eastman also help in having a considerable sound reduction.
