Turning Battery Waste into Sustainable Concrete
As Singapore accelerates towards its net-zero ambitions, an unexpected solution to two pressing environmental challenges is emerging from the laboratories of the Singapore Polytechnic (SP) Advanced Materials Technology Centre (AMTC). This latest innovation transforms spent graphite from decommissioned electric vehicle (EV) batteries into a valuable component for sustainable concrete production, creating a circular economy solution […]
Navigating Electricity Price Volatility: What Businesses Should Know about Energy Security in Singapore
Energy markets worldwide have experienced increased volatility in recent years, driven by movements in global fuel prices, supply chain disruptions, geopolitical developments, and weather-related factors. As a small, open and highly connected economy, Singapore’s energy landscape is acutely sensitive to global shifts. For businesses, particularly those managing commercial buildings and energy intensive facilities, it is […]
How can built environment companies remain competitive in the face of rising electricity costs and increasing corporate demands
Electricity bills for Singapore Small & Medium Enterprises (SMEs) have risen sharply in recent months. Spot tariffs that sat comfortably around $0.25 per kWh not long ago have drifted past $0.30 in the current supply environment, and businesses are now facing a very different market. For a small contractor, a fabrication workshop, or a family-run […]
Sustainable Concrete Incorporating Mixed Tyre Fibre Waste
Every year, approximately 26 million tonnes of tyres reach end-of-life globally, creating a significant environmental and waste management challenge. Despite ongoing recycling efforts, a substantial proportion of these tyres continues to be landfilled, stockpiled, or incinerated. Meanwhile, the construction sector’s demand for sustainable materials has grown steadily, driven by rapid urbanisation and there is an […]
Solar Heat Rejection Coating Transforms Glass Performance
Singapore Polytechnic’s innovative spray-applied solution delivers 8.85% cooling energy savings whilst maintaining natural light The Glass Dilemma in Green BuildingsGlass skyscrapers now dominate Singapore’s city skyline, offering aesthetic appeal and natural light, but glass itself is a poor insulator that allows excessive solar heat gain into buildings. This thermal inefficiency leads to increased cooling energy […]
Alternative Cooling Technologies – Accelerating the Transition towards a Low-carbon Built Environment
Singapore’s path to net-zero runs through our buildings, and cooling, which consumes 40-60 percent of building energy, is the single biggest lever we can pull. The Built Environment Decarbonisation Technology Roadmap published earlier this year identifies nearly 70 technologies. Among them, ACTs (Alternative Cooling Technologies) are highlighted as a key strategy for operational carbon reduction. […]
[CNA Commentary] How do we escape the air-conditioning trap?
This article was first published on the CNA website on 10 March 2026. The “air-conditioning trap” is real: as our cities get hotter, we use more AC, which pumps more heat into our environment, making cities even hotter. In his commentary piece on CNA, Prof. Khoo Teng Chye, Practice Professor with the College of Designand […]
Humidity Control: The Missing Piece of Sustainable Cooling
Singapore’s Go 25 movement encourages indoor air-conditioning setpoints of aorund 25°C to reduce energy consumption and advance net-zero targets. Yet in a tropical climate, temperature alone cannot deliver comfort, health, or energy efficiency if the air remains humid. Humidity control, specifically maintaining a lower dew point and approximately 50% relative humidity (RH). This is the […]

It is time to Rethink Carbon
For years, the green building conversation centred on energy efficiency. But the climate crisis demands a new focus: full-spectrum carbon accountability. As SGBC President Mr. Allen Ang highlighted at the Rethink Carbon event organised by the Institute of Real Estate and Urban Studies (IREUS) on 31 October 2025, embodied carbon – the emissions from manufacturing, […]
