Sustainable Cooling: A Cost-Effective Solution to Rising Heat and Emissions

A UNEP report highlights that adopting sustainable cooling strategies, including passive and low-energy solutions, could reduce cooling-related emissions by 64% by 2050, save trillions of dollars, and improve access for billions, amid rising global heatwaves and demand. The report advocates for policy integration, urban planning, and international cooperation through initiatives like 'Beat the Heat' to address the growing climate and health challenges associated with extreme heat.

"Revolutionary Colorful Paints: The Key to Drastically Reducing Energy Costs"

Engineers at Stanford University have developed colorful paints that can significantly reduce energy use for heating and cooling in buildings. These paints, which reflect infrared heat, can keep buildings cooler in the summer and warmer in the winter without using energy. In laboratory experiments, the paints reduced heating energy use by 36% and cooling energy use by 21%. Computer simulations showed a potential 7.4% reduction in total HVAC energy use for a typical mid-rise apartment building. The paints, available in various colors, are also water-repellant and stable in different climates.

"Revolutionary Passive Cooling PC Case Handles High-End Components Without Fans"

Streamcom's SG10 passive-cooled PC case can handle high-end CPUs and GPUs without any fans. The case features an aluminum body and a liquid coolant system that transfers heat away from major hardware components to the heatsink block. The company showcased an SG10 unit at Computex 2023, featuring an aesthetic design with glass side panels. The case can handle up to 600W cooling and supports popular high-end GPUs and CPUs. The NVIDIA RTX 4080 GPU was running at a TGP close to 300W and at full load, the temps only reached 60C. The aluminum variant will be priced at $999 US.

"Fanless PC Cases: Streacom and Thermaltake Push the Limits of Passive Cooling"

Streacom's SG10 passively-cooled PC chassis, based on loop heat pipe technology, can accommodate high-end gaming PCs without requiring active cooling fans. The case is rated to passively dissipate up to 600W of heat and has two cooling loops with two separate condensers for the CPU and GPU. The chassis is big enough to house an ATX motherboard, a graphics card that is up to 280 mm long, and five 3.5-inch/2.5-inch storage drives. The anticipated price for the case, along with all the required cooling assemblies, is around $999.

Innovative Materials and Techniques for Sustainable Energy Solutions

Researchers from Cambridge University are developing a cellulose film with passive daytime radiative cooling (PDRC) properties that can help cool buildings and cars without using air conditioning units or other active, power-intensive methods. The plant-based, two-layered material gets cooler when exposed to direct sunlight and can be treated to provide bright, iridescent colors and a variety of textures. The bi-layered film with PDRC properties was nearly 7F cooler than the surrounding air when placed under direct sunlight.
