10 Best Green Architecture Buildings in Singapore in 2024

What are Green Buildings?

Green Building, also known as sustainable construction, is a concept aimed at constructing high-performance structures without negative environmental impacts throughout their life cycle. It considers factors such as energy use, water usage, indoor environment, and occupants' lifestyle quality. Green Buildings promote a healthy and non-spoiled environment, reducing waste of natural resources and promoting a psychologically-optimised environment. It also offers lower construction costs, higher property value, improved health and productivity, and reduced utility bills. Green Buildings are ideal for growing and marketing green products, offering affordable go-green opportunities for existing homes, enhancing indoor air quality, and minimising strain on local infrastructure. The goal of sustainable construction is to control and maintain energy consumption, ensuring a greener, healthier life for future generations.

A green building uses recycled waste materials and other construction materials to create energy-efficient housing. Green building materials include green wood for flooring and cabinets, precast concrete slabs for indoor environments, straw bales for mud houses, and recycled plastics for interior decoration. Reclaimed wood and recycled steel are also used for durability. Implementing the Net Zero Concept, installing HVAC systems, using low indoor pollution emitting materials, and using Porotherm Bricks and green thermal insulation materials are also important. Solar power, smart grid appliances, and sustainable water management systems are also essential for energy conservation.

Green Buildings In Singapore - Why Is It Important?

Singapore Green Buildings has one of the world's most carbon-efficient economies and it aims to be sustainable in at least 80% of its buildings by 2030. Since 2005, Singapore has introduced innovations to integrate environmental sustainability into its built infrastructure, including "green buildings" that use recycled materials and green technologies. These innovations are made possible by an enabling environment that promotes sustainable construction materials and practices, aiming to create a clean, efficient, and liveable city.

Since 2005 Singapore has been working to make its buildings more sustainable, intending to make 80% of its structures green by 2030. They are minimising energy usage that accounts for more than 20% of total emissions in the country. The Green Strategy 2030 is a comprehensive green strategy that includes increased green spaces, improved public transportation, and the use of cleaner-energy vehicles. Passive design, which focuses on natural ventilation and heat absorption, is an important strategy for improving sustainable architecture in tropical Singapore. Building orientations are intended to capture wind currents and shield sun-facing facades from direct sunlight. Greenery on building facades and rooftops also helps to mitigate the urban heat island effect. Active methods such as energy-efficient lighting and sensors are also often used.

The Future Of Green Buildings In Singapore

The government's green initiatives and efforts contributed to the city state's remarkable sustainability progress in recent years. The government launched the expansive Singapore Green Plan 2030 in February 2021, a nationwide initiative to further the nation's sustainable development agenda. To improve the nation's commitments under the UN's 2030 Agenda for Sustainable Development and the Paris Agreement, the plan set out ambitious and specific targets for the next ten years, positioning the island state to meet its long-term net-zero emissions goals. The Building and Construction Authority (BCA) introduced the Singapore Green Building Masterplan (SGBMP) in March 2021 as a component of the Singapore Green Plan 2030. The SGBMP has three primary goals known as "80-80-80 in 2030." 

The targets of the master plan "80-80-80 in 2030" are: 

• By 2030, they aim to have 80% of new developments (by gross floor area) be Super Low Energy (SLE) buildings. 
• It will accelerate efforts to green 80% of buildings by that date.
• By 2030, achieving an 80% increase in energy efficiency for the best-in-class green buildings

Singapore is already setting an example for efforts toward creating a greener urban environment in the following years of COP26. The initiative's purpose was to provide the city-state with a distinct and visually pleasant image; it is today praised for its ability to handle urban heat issues, aid in sustainable water management, and increase biodiversity in the city. Numerous projects have been launched to address these critical challenges and to provide sustainable design solutions that would hasten the city's "greening."

Conclusion

Green buildings are a symbol of sustainable innovation and a conscientious approach to environmental preservation. They go beyond conventional structures and are a fusion of thoughtful design, technology, and environmental responsibility. Singapore, known for its ambitious targets, aims to make 80% of its buildings sustainable by 2030. The Singapore Green Plan 2030 and the Singapore Green Building Masterplan demonstrate the city-state's proactive stance in aligning with global sustainability goals. The architectural wonders in Singapore, such as the Oasia Hotel Downtown, Gardens by the Bay, and the Nanyang Technology University, represent a vision of embracing nature, harnessing technology, and fostering a symbiotic relationship between humans and the environment. The future of green buildings in Singapore holds great promise, as it focuses on weaving sustainability into the urban fabric, fostering innovation, setting higher energy efficiency benchmarks, and inspiring a global shift towards a more sustainable and eco-friendly built environment.
