Building Sustainable and Energy Efficiency in Smart Cities

One of the challenges in building a city or converting older infrastructure in a SMART CITY is the topic of ENERGY. Industries globally are having to reassess their energy production and saving standards either through choice or governance. About 85% of the energy consumed in modern society comes from fossil fuels.

OTSAW’s policy on energy started with the O-RX, UV-C LED, autonomous disinfection robot, where our call to tackle the global challenge of energy reduction through sustainability measures, went hand in hand with innovation from conceptualization, to manufacturing and production of autonomous robots.

By using UV-C Led technology, it is 70% more energy efficient as compared to conventional mercury lights. LEDs release a minimal amount of heat from the front side. For heat sensitive applications, LED lights generate heat through the back from the chip. Active cooling techniques can help with thermal management. Products using mercury lamps, have a warm up time and various factors that affect the stability of the light (temperature, power supply, construction design).

Overall, Asia’s energy transition isn’t as fast as it should be, with insufficiencies to curb emissions. Reducing reliance on coal, accelerating the deployment of renewable energy sources, developing hydrogen and improving energy efficiency are key to lowering the region’s carbon footprint, reported the Business Times.

Asia’s system is heavy reliant on thermal coal, generating the most CO2 emissions of any fossil fuel. The reliance on coal in Vietnam, Indonesia and the Philippines has remained on an uptrend.

We round up the latest news in the energy sector around Singapore:

Singapore’s Drive Towards Electric Powered Mobility

Aspirations centring around the Singapore Green Plan 2030, including that of a long term goal of net zero-emissions, as a nation we were shocked at the announcement of the phase out of all internal combustion engine (ICE) vehicles by 2040, with electric vehicles (EVs) to take over the roads.

With an obvious lack of charging infrastructure, the government changed the barrier to entry with plans to expand the number of EV charging points from 1,600 to 60,000 by 2030, and to have a minimum of eight “EV-Ready Towns” by 2025, with HDB car parks fitted with EV charging points. LTA and EDB, which co-chair the Electro-Mobility Singapore (EMS) taskforce, announced that Type 2 AC and Combo-2 DC charging systems would be adopted as the National Public Charging Standards (NPCS).

An e-mobility system is being put into process to build upon an ecosystem, creating a new area for e-mobility energy management.

Singapore’s Green Building Masterplan (SGBMP)

Research has shown that buildings account for more than 20 per cent of Singapore’s emissions. Experts say the issue lies in the process of tearing down and re-building is highly carbon-intensive and not all materials can be recycled. It’s a vicious cycle producing new materials, transporting them and constructing another new building. The goal through research and innovation for cleaner energy and to increase Singapore’s energy efficiency is through three targets.




Singapore’s Green Buildings

Buildings in Asia often account for a higher percentage of greenhouse gas emissions than the worldwide average,” said Philippe Delorme, executive vice-president for energy management at Schneider Electric.

Smack in the city central, South Beach by City Developments (ranked as Asia’s most sustainable property developer in 2021 by Corporate Knights) is able to funnel existing winds over outdoor clients of F&B businesses, saving on air conditioning. The canopy is covered with solar panels and catches rainwater to irrigate the gardens. The complex can achieve 30 per cent energy savings compared with a traditional building.

“There’s a clear environmental benefit to building green but investing in green building also means significant operating cost savings, shorter payback periods and an overall increase in the value of these assets,” said Melissa Baker, senior vice-president of LEED technical development at the US Green Building Council. 

Singapore Airlines Targets Net Zero Carbon Emissions by 2050

Though ambitious, Singapore Airlines, Scoot and SIA Cargo is committing to a net zero carbon emissions standard across all of its operations. Strategies include new-generation aircrafts; achieving greater operational efficiencies; exploiting low-carbon innovations (such as low-carbon fuels); and more aggressively sourcing carbon offsets.

Mr. Goh Choon Phong, Chief Executive Officer, Singapore Airlines, said they have retired 45 older aircrafts replacing them with newer generation jets that are up to 30 percent more fuel efficient that will lower emissions. SIA aims to continuously improve fuel productivity through a range of initiatives by reducing fuel consumption via aircraft weight management to computer optimization of flight routes.

The SIA Group will continue exploring partnerships to source high quality carbon offsets such as completing the installation of solar panels on all of its office buildings in Singapore.
