NaƟ onal Environment Agency wins internaƟ onal engineering award The award honours Singapore’s Semakau Landfi ll where nature and landfi lling operaƟ ons co-exist

NATIONAL ENVIRONMENT AGENCY WINS INTERNATIONAL ENGINEERING AWARD

The award honours Singapore’s Semakau Landfi ll as the fi rst off shore landfi ll in the region where nature and landfi lling operaƟ ons co-exist.

The National Environment Agency (NEA) has been recognised for its outstanding engineering feat in the development of Semakau Landfill. NEA received the 2019 Hassib J Sabbagh Award for Engineering Construction Excellence, from the World Federation of Engineering Organizations, at an award ceremony held in late November 2019, in Melbourne, Australia. This prestigious international award affirms the role of engineering in sustainable development. Underlining the theme for the 2019 Award, which was ‘Sustainable Development for Smart Cities’, Semakau Landfill showcases how sustainable waste management can co-exist with flora and fauna. The development of Semakau Landfill, the first offshore landfill in the region, is proof of Singapore’s innovative spirit and strong engineering capability, in response to the twin challenges of Singapore’s growing waste generation and severe land constraints. This unique approach to waste management balances national development and biodiversity conservation in an environmentally sustainable way.

Semakau Landfill’s Success Story Launched on 1 April 1999, Semakau Landfill achieved several engineering feats, including in deep-sea piling and open sea construction that required the use of large floating cranes for installation of the roof structures. Adding to the challenge was the need to preserve the island’s biodiversity before landfill operations began. Mitigation measures included the replanting of about 400,000 mangrove saplings on two new plots at the northern and southern fringes of the original island during the Phase I development, as well as the harvesting and transplanting of over 700 colonies of corals in the Phase II lagoon to Sisters’ Island. Over 80 species of birds, inclusive of some endangered species, have been spotted around Semakau Landfill. The thriving coral colonies and wild birds in their natural habitat on Semakau Landfill show that the landfill operations and preservation of the local natural environment can both be achieved, at the same time. Winning the award was particularly significant, as Semakau Landfill had just crossed the important 20th anniversary milestone. The purpose of the Hassib J Sabbagh Award is to direct the world’s attention to the role of engineering in sustainable development. The award also includes a cash prize of USD 10,000 which

NEA will be donating to a WFEO project on capacity building for climate change education in the Small Islands Developing States (SIDS). The donation, which will fund training and teaching aids for climate change awareness in schools, underscores NEA’s and MEWR’s (Ministry of the Environment and Water Resources) commitment to international and regional cooperation for climate action, and in supporting developing countries in climate change mitigation and adaptation. Mr Tan Meng Dui, Chief Executive Officer, NEA, said, “Achieving this award is a significant milestone, particularly for a relatively young organisation like NEA. The timing of the award is also special and gratifying, as we celebrate Semakau Landfill’s 20th anniversary this year. We are honoured to receive this award, and proud of our engineers who have combined their inventiveness with sheer determination and hard work to great effect, in developing Singapore’s first offshore landfill. The current generation of NEA engineers stands on the shoulders of the past generation. This award is therefore also a recognition of the industry and pioneering spirit of the engineers and leaders that have come before us. I hope this award will inspire everyone in Singapore to all do our part and work together to preserve Semakau Landfill and lengthen her lifespan beyond 2035”.

An outstanding engineering feat.

KONE DX CLASS ELEVATORS WITH BUILTͳIN DIGITAL CONNECTIVITY AS STANDARD

KONE, a global leader in the elevator and escalator industry, has introduced what the company says is the world’s fi rst digital elevator series. With built-in connecƟ vity as standard, KONE DX Class elevators bring a new user experience to life through a combinaƟ on of design, technology, new materials, apps and services. With the KONE DX Class, the role of elevators in future smart buildings is expected to change. The elevator is no longer merely a way to travel between fl oors but becomes an integral and integrated plaƞ orm that off ers intuiƟ ve, ambient and connected experiences that extend from the lobby throughout the building. For KONE customers such as developers and building owners, a key advantage is the ability to adapt and upgrade the elevator experience according to present and future needs. The new KONE DX Class enables customers to tailor and plug in addiƟ onal soŌ ware and services for elevators throughout the enƟ re lifeƟ me of a building. By using open applicaƟ on programming interfaces (APIs), KONE’s approach makes it easy to manage and integrate diff erent devices, apps and services with new and exisƟ ng systems. For elevator passengers, this brings a host of new, mulƟ sensory experiences inside the elevator, combining physical hardware and digital services. These can be customised according to individual needs and preferences, bringing new levels of ease and convenience. Every KONE DX Class elevator provides the following: • The opƟ on for customers to easily and remotely acƟ - vate digital services when they need to, including KONE 24/7 Connected Services and KONE ResidenƟ al Flow. • Secure APIs for third-party soluƟ ons which create new and exciƟ ng services. KONE is also announcing agreements with a number of companies to bring new levels of sophisƟ caƟ on to the people fl ow experience. • A variety of new design opƟ ons and innovaƟ ons, including anƟ -stain, anƟ -scratch, and anƟ -bacterial surfaces. • Advanced dynamic display, sound and lighƟ ng opƟ ons to transform the ambience and interior. • A range of sustainable materials to meet green building criteria like BREEAM and LEED. The new KONE DX Class elevator series became available in European markets from December 2019 onwards and is expected to be rolled out to other areas during 2020 to 2021. The KONE DX Class is also ideal for customers looking to modernise exisƟ ng equipment with enhanced eco-effi ciency, performance, and aestheƟ cs. The KONE DX Class is expected to replace the current KONE elevator range.

SIEMENS ENABLES HOLISTIC ENERGY DATA ANALYSIS IN BUILDINGS

At this year’s Light+Building 2020 trade show, to be held in Frankfurt, Germany, from 8 to 13 March 2020, Siemens Smart Infrastructure will present the fi rst energy management soluƟ on that holisƟ cally captures energy data in buildings. It collects data all the way to the fi nal circuit without any addiƟ onal wiring or space requirements. All electrical data, from the power feed-in to the socket outlet, can then be seamlessly integrated into building management systems and analysed by cloud-based applicaƟ ons. This makes the electrical infrastructure an integral part of smart buildings that are connected via the Internet of Things (IoT). Operators and users gain maximum transparency over their energy fl ows and benefi t from end-to-end digitalisaƟ on.

DigitalisaƟ on of electrical installaƟ ons With the new 5SL6 miniature circuit breakers (MCB) and 5SV6 arc fault detecƟ on devices (AFDD) from the Sentron porƞ olio, Siemens brings digitalisaƟ on to electrical installaƟ ons. The compact devices combine overload, short circuit and arc fault protecƟ on with integrated communicaƟ on and measuring funcƟ ons in just one modular width (MW). They can measure electrical values such as current and voltage, as well as temperature and switching states for individual circuits and automaƟ cally idenƟ fy error causes. Operators and electrical installers can quickly recognise loads with increased power consumpƟ on, as well as anomalies and disrupƟ ons in the electrical installaƟ on and intervene early on. All the data can be visualised on a PC, tablet or smartphone and connected to analyƟ cs tools and digital environments through the new 7KN Powercenter 1000 gateway.

Integrated building and energy management The updated Sentron ‘powermanager’ power monitoring soŌ ware consolidates building and energy management in one single plaƞ orm. Version 4.x can be used as a standalone soŌ ware or, for the fi rst Ɵ me, integrated into the Siemens Desigo CC building management system as an expansion module. This allows all energy distribuƟ on and building automaƟ on systems to be operated, monitored and managed from a single system. Sentron ‘powermanager’ analyses electrical parameters such as voltage, currents and power quality. Especially, small and medium-sized businesses benefi t from the easy-to-use soŌ ware. They can easily idenƟ fy potenƟ al savings or system errors, reduce energy costs and cut CO 2 emissions. All analyses can be shown in fl exibly confi gurable dashboards or report templates and assigned to cost centres. Users are automaƟ cally noƟfi ed by e-mail or text messages (SMS) of irregulariƟ es in energy consumpƟ on or unusual system behaviour.

In addiƟ on, integraƟ on in Desigo CC enables regression analyses. By comparing consumpƟ on data with informaƟ on from presence detectors, for example, it can be determined if energy for lighƟ ng, heaƟ ng or air condiƟ oning is being used in temporarily unoccupied parts of the building. If electrical systems such as elevators or escalators consume an unusually large amount of electricity, this can be similarly compared with the maintenance intervals defi ned in the building management. If necessary, these must be shortened to avoid expensive repairs and breakdowns.

Real-Ɵ me energy data analysis via app The new Sentron ‘powermind’ app analyses energy data directly in MindSphere, the cloud-based, open IoT operaƟ ng system from Siemens. Users see a real-Ɵ me overview of current energy consumpƟ on and trends over Ɵ me - both for enƟ re systems as well as for individual electrical loads. The app is easy to use and requires no specifi c IT skills, allowing even inexperienced users to enter the world of digital energy management.

The new electrical installaƟ on devices from Siemens combine protecƟ on and measurement funcƟ ons in a single unit.

All the energy data from the electrical installaƟ on can be connected to analyƟ cs tools and digital environments through the new 7KN Powercenter 1000 gateway.

SMART BUILDING SOLUTIONS TO HELP BUILDINGS ACHIEVE ENERGY SAVINGS

SP Group (SP), a leading energy uƟ liƟ es group and 75F, a building intelligence soluƟ ons provider, are off ering a micro-climate control soluƟ on that can save more than 30% in energy consumpƟ on while improving occupant comfort.

The soluƟ on uses applied ArƟfi cial Intelligence (AI) and Internet of Things (IoT) to reduce energy consumpƟ on in a building.

It takes into consideraƟ on factors like occupancy and weather and opƟ mises air-fl ow to evenly cool areas. SP partnered with 75F to customise and test the performance and viability of the soluƟ on for Singapore’s tropical environment. The soluƟ on was trialled for a year at Singapore InsƟ tute of Technology’s (SIT) campus at Dover and Mercatus Co-operaƟ ve Limited’s corporate offi ce at One Marina Boulevard in Raffl es Place.

Both locaƟ ons achieved more than 30% in energy savings, while improving comfort for occupants by ensuring that the indoor temperature and air quality were opƟ mal. With the validated outcomes, SP and 75F will off er the soluƟ on to customers in Singapore, China, Vietnam, Indonesia and Australia. Air-condiƟ oning contributes 60% of a building’s electricity consumpƟ on.

With buildings consuming a third of Singapore’s total electricity consumpƟ on, this new soluƟ on will help the country reduce electricity consumpƟ on and support the goal of cuƫ ng naƟ onal emissions intensity by 36% below 2005 levels, by 2030.

The micro-climate control solution is a self-learning, intuitive building intelligence system that optimises and regulates air-conditioning in buildings to improve operational efficiency and occupant experience.

The system’s central control unit divides large open spaces into smaller zones that balance the temperature, air flow and carbon dioxide (CO 2 ) within each zone.

It also opƟ mises the air-condiƟ oning operaƟ on by using the least amount of energy to achieve the required comfort. SP’s partnership with 75F first started as part of SP’s Energy Advanced Research and Development (SPEAR) programme, under the SP Centre of Excellence (SP CoE).

IES APPRECIATION & AWARDS NIGHT AND SPRING FESTIVAL 2020

Every year, IES acknowledges the eff orts and contribuƟ ons of its volunteers through the AppreciaƟ on & Awards Night. This year, the ceremony was held on 6 February 2020 at Qian Xi (Farrer Park) Restaurant, located at Civil Service Club @ Tessensohn. It was also an occasion to gather and usher in the Year of the Rat, with the Spring FesƟ val celebraƟ ons being held concurrently, adding to the fesƟ ve atmosphere in spite of the ongoing coronavirus (COVID-19) situaƟ on. PrecauƟ onary measures were taken to ensure peace of mind amongst the 250 guests, IES staff , and the restaurant workers. Temperature screenings were conducted, all guests submiƩ ed their travel declaraƟ ons, and hand saniƟ sers were readily available. The emcees also encouraged guests to adopt alternaƟ ve forms of greeƟ ng such as waving or clasping of hands, so as to minimise physical contact. Taking the change of pace this year in their stride, the two lions from Nam Sieng Lion Dance Troupe pranced through the restaurant before “plucking the green” (cai qing) on stage, blessing all in aƩ endance with good fortune for the year. In his opening address, IES President Prof Yeoh Lean Weng thanked all volunteers, partners and staff , and spoke briefl y about the InsƟ tuƟ on’s achievements and highlights in the past year. Special menƟ on went to the Charles Rudd DisƟ nguished Public Lecture, which was put together within two months and aƩ racted more than 1,000 parƟ cipants. The evening’s activities were rounded out with perennial favourite Bingo, which got everyone excited as they looked out for the numbers flashed on the screen that determined if they had the fortune to bring home some chocolate, hampers, or wine bottles this year. Some guests also made use of the venue’s karaoke system, belƟ ng out tunes both classic and contemporary, entertaining all who were sƟ ll present. It was a great celebraƟ on indeed, both of the past year’s eff orts, as well as the advent of the new year. Cheers to a successful 2020 ahead! Prof Yeoh receives blessings from the lions on behalf of all members. May everyone have good health and wealth in 2020!

He also encouraged members to step forward with ideas on how the community could be beƩ er-served, as IES embarks on a new journey this decade as a “family of engineers”. A total of 39 awards were given out that evening, such as the Outstanding Volunteer, Outstanding CommiƩ ee, and Special RecogniƟ on Awards (see full list on pages 47 – 48). Amongst our student chapters, NUS came out on top in the University category, while the young engineers-in-training at Temasek Polytechnic took home the Ɵ tle in the Polytechnics category. We also presented the Friend of IES Awards to our valued partners in graƟ tude of their conƟ nued support and partnership with us for the benefi t of all engineers.
