< Previous ELEVATOR DATA 30 January 2022www.fm-middleeast.com K ONE, a global leader in the elevator and escalator industry, has analysed data from its global elevator portfolio to tell the story of the flow of people in cities around the world over the course of the Covid-19 pandemic. The data collected covers the period from before the first lockdowns confined most populations to their homes, to the present day, and provides an original data set for illustrating the return of people to workplaces, educational institutions, hotels and within residential buildings. Equipment designed and manufactured by KONE moves over one billion people every day in its customers’ buildings. OFFICE ELEVATOR USE IN LONDON DROPPED 80% AT THE HEIGHT OF THE PANDEMIC The data shows that in the top 10 European cities where KONE has comprehensive elevator data showing the movement of people, the average number of office elevator journeys plummeted by 80% between February and April 2020. In London, the average number of starts per elevator in September 2019, before the pandemic, was around 13,000 in office buildings. By April 2020, the average number of journeys per elevator had fallen to around 2,500. In Amsterdam, the average number of starts per elevator in office buildings in September 2019 was around 16,500. By April 2020, the monthly average number of journeys had fallen to under 3,500 per elevator. In the latest figures for November 2021, elevator use in London had rebounded to 72% of pre-pandemic levels, with the average KONE elevator making around 9,200 journeys in November. However, the rate of increase of elevator usage in Europe stalled, or even fell between October and November, potentially reflecting the change in people’s behaviour or new restrictions on movement in response to the discovery on the Omicron variant in the second half of November. For instance, in Amsterdam, the average number of journeys per office elevator was just under 9,000 in October, but fell to 7,900 in November. Other European cities in the top 10 of KONE’s portfolio – Berlin, Brussels, Hamburg, Helsinki, Milan, Munich, Paris, and Stockholm - have all seen steady rises in office elevator use since the depths of the first lockdown, though the return to office buildings in all of them has abated or fallen since October. HOTEL SECTOR’S RECOVERY HAS REVERSED IN THE LAST MONTH The data for hotel elevators tells the dramatic story of the pandemic. From a monthly peak of over 22,000 starts per hotel elevator in September 2019, this number plummeted almost 90% to around 2,500 starts per hotel elevator by April 2020. Although the monthly number of average journeys per hotel elevator in London recovered to around 19,000 in October 2021, this number fell to under 18,000 in November. This fall in hotel elevator usage has been replicated in Amsterdam, Stockholm, Berlin, Paris, Hamburg and Munich. THE GLOBAL PICTURE SHOWS THE NUMBER OF PEOPLE LIVING IN CITIES IS PREDICTED TO RISE FROM FOUR BILLION TODAY TO MORE THAN SIX BILLION BY 2050. ELEVATOR DATA January 2022 31www.fm-middleeast.com NATIONAL DIFFERENCES WHEN IT COMES TO THE RETURN TO THE OFFICE Since January 2021, a more nuanced picture has emerged from KONE’s elevator data for office buildings, which reflects different Covid-19 strategies in individual countries. For example, in Shanghai at the start of the year, when China’s workforce had largely returned to typical working patterns, the monthly average number of starts per elevator stood at 18,300, but as of last month, the average number of monthly journeys had dropped to fewer than 15,000. Whereas in Chicago, which still had strict restrictions in place at the start of this year, elevator usage has grown slowly and steadily since January, reflecting the United States’ systematic approach to managing the pandemic, and people feeling safer to return to the office. Tessina Czerwinski, programme director, smart and sustainable cities at KONE, commented: “The number of people living in cities is predicted to rise from four billion today to more than six billion by 2050. We need to accommodate and help all these people move around in cities in a sustainable way. Technology enables us to create personalised, even safer ways to connect people and places. Elevator data can teach us a lot about how life has changed over the past couple of years – and it can also teach us how life might change in the future. “Throughout the pandemic, though, one of the principal variables has been the specific national coronavirus restrictions at a particular moment in time, which is where we start to see different cities navigating different journeys through the crisis. For instance, at the start of 2021, the United States, Europe, and China were at completely different covid recovery stages with different rules on the movement of people, which is reflected in the way people have been travelling up and down office, hotel, educational and residential buildings this year.” COMMENT 32 January 2022www.fm-middleeast.com The elevator industry is among those that play an instrumental role in supporting rapid urbanisation By Mohammed Al Qaisi, managing director, Otis Gulf A ccording to the World Bank and the United Nations, 70% of the world’s population will be living in cities by 2050, compared to 55% today. The population in the Gulf is predicted to grow in line with this upward trend reaching 57 million by 2025, with an additional 14 million people expected to call the region home by 2050. A core priority for governments is to develop sustainable urban environments that support population growth and simultaneously contribute to the realisation of ambitious national visions. Across many regions of the world, infrastructure improvements and the development of world-class real estate are a part of this trend, and we see this in the Gulf as well. For instance, based on the Abu Dhabi Economic Vision 2030, this emirate will go on capitalising on its strategic position and rely on the construction and engineering industries in the next decade as key enablers of economic success. Investment in infrastructure and construction is also on the list of the paramount economy- driving pillars in Qatar National Vision 2030 and Kuwait’s National Development Plan until 2035. The elevator industry is among those that play an instrumental role in supporting rapid urbanisation. It is vital for residential and commercial buildings, critical facilities such as hospitals, and DIGITALISATION IN THE ELEVATOR INDUSTRYCOMMENT January 2022 33www.fm-middleeast.com overall infrastructure – including mass transit. In fact, Otis elevators alone move 2 billion people a day worldwide. As a pioneer of the industry in the mid- 1800s, Otis has been at the forefront of the evolution of elevators. They have progressed from being relatively simple machines that safely delivered a passenger to their desired floors in early high-rises, to a building system that is crucial to efficient building operations with passenger experience and safety at its core. Like many industrial sectors, ours is constantly evolving, driven by ambitious architectural designs, customer needs and expectations, as well as new, innovative technologies. We enhance our elevator platforms by leveraging automation and artificial intelligence for better performance and service. In fact, customers are increasingly requiring this advanced technology as standard. This applies to every aspect of elevator equipment – from ensuring safety and comfort to contributing to a building’s log faults, performance and equipment health and consequently choose proactive measures matching the overall estate handling plan. As more data is collected, it can be shared with building managers so they can make informed decisions about other building systems or can even use algorithms to do so – such as using elevator passenger data to notify the HVAC system of a crowd heading to one floor for a large meeting. The future of infrastructure management lies in such smarter and more digitally packaged solutions. As the region embarks on the development of sustainable, smart cities, the applications of technology to truly integrate elevators within a building’s management system are vast. The elevator industry has embraced digitalisation, and smart systems have become an integral feature in products. Today, we can analyse the performance, optimise equipment, prevent failures and better plan capital investments. Tomorrow, there is the potential for the integration of fire alarm systems, facial recognition systems for touchless solutions, and much more. The possibilities are endless. energy efficiency goals. Otis elevators are part of a building’s technical ecosystem. “Smart,” or connected, elevators leverage digital technologies such as the Internet of Things (IoT) and Artificial Intelligence – and we have over 450,000 such connected units worldwide. These technologies allow Otis teams to use sensors to collect and interpret information in real-time and enable us to continuously monitor the key elevator parameters, operational function and performance. This data has enormous potential for building managers and passengers. Imagine each elevator constantly connected to a cloud service. Using AI, we are able to implement predictive maintenance to identify potential problems before they occur and correct them remotely or dispatch a service technician to make the repair faster because they are better informed about what needs to be done prior to the visit. This significantly reduces the downtime of the elevator increasing operational reliability and availability, as well as passenger safety and comfort. Alongside predictive maintenance, these smart elevator management systems go in line with sustainable consumption trend and change the overall approach to power usage. While some elevators use a significant share of building’s energy, we can implement dispatching algorithms that would bring a twofold benefit to the building’s environment – the algorithms can effectively manage the passenger flow and optimise elevator performance reaching a marked reduction in electricity consumption of an elevator. This is a win-win solution for the building owners, tenants and their guests. In the Gulf region, Otis has introduced an innovative solution that makes elevator data more transparent and available. This includes an online portal and a mobile app that provides instant performance analytics and round- the-clock access to critical elevator equipment and service information. With this solution, building owners and management companies can track THE ELEVATOR INDUSTRY HAS EMBRACED DIGITALISATION, AND SMART SYSTEMS HAVE BECOME AN INTEGRAL FEATURE IN PRODUCTS.

STANDARDS 34 January 2022www.fm-middleeast.com The world’s first residential property to be certified with the IMMUNE Building Standard has been unveiled in London, UK. One Palace Place ONE PALACE PLACE INCORPORATES 35 PRIVATE APARTMENTS WITH A 24/7 CONCIERGE FOR RESIDENTS in London, a luxury residential building managed by Navana Property Group, was awarded the IMMUNE - Strong label by the Healthy by Design Building Institute (HDBI), marking the first residential property to receive this distinction. An initiative by Genesis Property, a leading member of the European Property Federation and a renowned Class A office developer, the award was in THE WORLD’S FIRST IMMUNE CERTIFIED RESIDENTIAL BUILDING UNVEILED IN LONDONSTANDARDS January 2022 35www.fm-middleeast.com recognition of Navana Property Group implementing the recommended measures of the IMMUNE standard across the built environment at One Palace Place to create a healthier living environment for residents. Located in the prestigious borough of Westminster, One Palace Place incorporates 35 private apartments with a 24/7 concierge for residents, alongside a 312-seat theatre, a 120-seat studio, as well as a restaurant and bar open to the wider public. The achievement of the IMMUNE certification reflects how Navana Property Group successfully implemented a large majority of the 135 measures included in the IMMUNE Assessment Scoring Index. They include: • aligning its policies to the IMMUNE standards at a corporate level, especially in areas such as business continuity, recovery, and wellbeing • providing additional training to its onsite team and the dedicated IMMUNE Steward • increasing the cleaning frequency of high touch and footfall areas such as access and exit routes, the entrance, lifts, stairwells, doors and handles with supporting signage • enhancing sanitation regimes within the building both for its staff, residents, visitors, and contractors to keep them protected • providing PPE equipment • installing 8 automatic hand sanitisers in the main entrance and lift lobbies on each floor of the building. Build Green, an independent authorised building assessor and a contributor to the development of the IMMUNE Building Standard, performs the evaluation and recommends a property to become IMMUNE - certified with one of the three labels: Strong (3 stars), Powerful (4 stars) or Resilient (5 stars). The IMMUNE Building Standard was developed in 2020 to combat effects of the Covid-19 pandemic and to design healthy indoor spaces, including offices, industrial buildings, and starting this year, residential buildings. By covering residential buildings, the standard marks a new major expansion milestone, boosting its contribution to the resilience of a wide range of built environments against the health threats of today and beyond. The IMMUNE Building Standard is based on practical investment in a Healthy by Design System (HbDS), which incorporates a network of specialised sensors that measure the indoor environment parameters such as air, humidity, temperature, or CO2 levels. Data on the building’s performance is collected in real time, empowering the building operator to verify and adjust the condition of the building to a healthy performance level to provide occupants with the space and confidence for a healthy living experience. Every IMMUNE certified building incorporates advanced technologies, specialised equipment, and dedicated personnel, an IMMUNE Steward, to manage the building’s operations and health parameters, as recommended in the standard. “This is another major step in our journey that started in April 2020, shortly after the outbreak of the Covid-19 pandemic, when we researched and developed the IMMUNE Building Standard as a blueprint for healthy buildings of the future. We’ve come a long way since and we have leveraged relevant expertise in creating healthier built environments where people spend most of their time indoors be it at home or at work. Our track record with this innovative standard and Navana’s visionary approach led to the first IMMUNE certified residential building in the world, paving the way for our post-pandemic homes”, said Liviu Tudor, Founder of Genesis Property and President of the European Property Federation. “Last year people probably spent more time at home than ever before, but while we’ve seen changes in the way offices, transport hubs and shops are managed to keep people safe, there’s been little discussion about what should happen in a multi-residential setting. People want reassurance, particularly as we learn to live with Covid-19 and prepare for possible future outbreaks. This is not about creating sterile spaces, but about making sensible design and management changes. IMMUNE certification shows our commitment as a professional property and asset manager to do everything we can to keep our customers healthy and well,” said Mark Fitzgerald, managing director of Navana Property Group.

Before the pandemic, it would be deemed “disruption”; today, it’s transformation. And for its part, the hospitality industry has assimilated into digital reality at an exemplary rate. The global smart hospitality market is forecasted to grow at a CAGR of 21.63% from 2020 to 2027(1). So, what are potential adopters hoping to achieve? First and foremost, hotels are complex structures comprising multi-vendor units such as HVAC, lighting systems, plumbing fixtures, central boilers, guest room management systems, security and access control, building management systems, etc. And since the industry is predominantly service-driven, there is no room for compromises in any system. Furthermore, the industry is increasingly coming under scrutiny for its resource- intensive nature. So, with technology adoption and implmentation, hospitality professionals are hoping to optimise energy usage, guest experiences, and routine operations, while reconciling these with long-term ROI and incremental savings. Here are five ways these multi-fold objectives are achievable through smart property solutions. 1. Vendor-agnostic integration: The cornerstone of smart hospitality is the IoT-led integration of all systems and functions, irrespective of vendor lock-ins and licenses. Enterprise-grade solutions will seamlessly integrate multi-vendor systems, creating an open-protocol ecosystem and centralising the control under one roof. Operators can thus FIVE WAYS SMART PROPERTY SOLUTIONS CAN REVOLUTIONISE THE HOSPITALITY INDUSTRY SMART HOSPITALITY By Sanjeevv Bhatia, chairman of SB Group and CEO of Netix Global BVwww.fm-middleeast.comJanuary 2022 37 SUPPLIER FOCUS in their ability to constantly stay ahead of the curve. Thanks to the open- protocol ecosystem characterised by interoperability and programmability, hoteliers can seamlessly integrate state-of-the-art products/services and continue to maximise value and savings. In an industry as competitive as hospitality, such agility and future- readiness are highly desirable. These can differentiate the brand, enabling hoteliers to retain guests and rake in profits. Incrementally, savings related to energy, replacement of manual operations, and predictive maintenance will add significantly to the ROI. 5. Sustainable transformation: According to an estimate, hotels in Dubai are using as much as 1,250 litres of water per guest — which is 225% more than the European average(2). Such overuse prompted Dubai’s Department of Tourism and Commerce Marketing to mandate compliance with the Sustainability Requirements for Hotel Establishments. In light of this, and in anticipation of similar regulations to come, smart solutions make a compelling case for adoption. By automatically making energy-efficient adjustments like dimming the lights, changing HVAC settings, and sending alerts on overuse or shutting off the air-conditioner in ‘door/ window left open’ cases, such solutions empower hoteliers to align better with sustainability goals. SMART HOTELS ARE COMING OF AGE IN THE UAE In the recently held physical edition of the Stakeholder Conference 2021 — hosted by the Hospitality Network — smart property solutions made quite a mark, featuring in experience rooms. Attended by nearly 200 key stakeholders from the global hospitality industry, the conference set the stage for the next growth phase led by smart solutions. Furthermore, stakeholders caught a glimpse of plug-and-play retrofits that can turn existing hotels into smart ones. The intelligent Integrated Building Management Solutions (iIBMS) and associated solutions like self-contained, perform real-time monitoring and commissioning. The single-window visibility into hotel-wide systems and processes will enable operators to give timely alerts, optimise workflows, and streamline operations of all — kitchen, administrative, and housekeeping — staff. 2. Optimisation of processes and devices: Integration brings visibility into end-to-end hospitality processes, revealing areas that can be optimised. This capability, combined with centralised and automation-heavy operations, can unlock unprecedented efficiencies. Instead of error-prone manual operations and reactive remedial actions, hoteliers can thereafter be proactive in addressing issues and inefficiencies. This is consequential in hotels, considering they harbour systems that could seem fine only to stop functioning when guests are checked in. Conversely, in smart hotels, IoT sensors — like plumbing sensors that detect and report leaks — will enable quick remediation of issues, before they can disrupt guest experiences. Novel solutions can also detect root causes and diagnose them automatically, thus maximising equipment lifespan. 3. Personalised guest experiences: Hospitality is arguably the most experience-driven industry. And this distinction has come at a cost. Hoteliers are often in the market for best-in- class systems that can potentially enhance guest experiences. Therefore, experience enhancements have strong financial implications in the industry. But smart property solutions beg to differ. The combination of automation, IoT sensors, AI, and monitoring-based commissioning helps hoteliers deliver disruption-free experiences. These, combined with adaptive comfort and on-demand services, constitute superior guest experiences. In fact, following the pandemic outbreak, smart hotels are performing insight-led sanitisation and delivering contact-less services as part of the expanding hospitality experience. 4. Constant upgrades and incremental savings: The charm of smart hotels is cloud-connected emergency lighting, maintenance-free supercapacitors, fully integrated central battery systems, and progressive GRMS solutions were among the notable ones on display. The emergence of retrofit smart solutions are particularly consequential to the UAE hospitality industry due to the sizable stock of relatively old hotels. While new ones are characterised by cutting-edge technology and efficient operations, old ones run the risk of becoming obsolete. However, hoteliers cannot consider replacing the entire hardware due to the high costs involved in the process. To this end, smart retrofits and upgrades offer the most viable solution to future-proof old hotels by helping owners/operators shed their dependence on OEMs, and enhance their competitiveness. This can be termed the “android approach” to operations and maintenance, using which hotels can become open-protocol, vendor-neutral, and highly programmable — much like the Android operating system in mobile phones. With greater adoption, this approach could help the entire hospitality industry make great strides in digitalisation and emerge out of the current great reset enthusiastically.
