Japan introduces solar heat-blocking pavements
The host city of Olympic and Paralympic Games in 2020, Tokyo is working on heat blocking methods during the summer.
Tokyo : The host city of Olympic and Paralympic Games in 2020, Tokyo is working on heat blocking methods during the summer.
Among various measures, originally research and practical application of a thermal barrier applied to pavement has been advanced to reduce a rise in temperatures from the summer heat.
It is the technology to apply a heat shield that reflects the sunlight causing the rise of the temperature of the road surface.
This solar heat-blocking pavement reflects incoming sunlight, making it difficult to heat the pavement and can reduce the rise in road temperatures by up to eight degrees Celsius.
Noise reduction technology has also been applied to Japanese roads to mitigate road noise.A thermal barrier coating is applied to the surface of the noise reduction pavement and is compatible in suppressing noise of the road surface.
As a part of research and development, tests have also been done to observe changes in temperature in multiple types of pavements.
The effect of the heat barrier pavement, which suppresses the rise in temperature of the road, can be measured using various devices or methods, including thermography.
At present, the center of Tokyo has been the focus of this application. It has been performed accordingly during road repairs.
Nishioka said, "I believe that this technology can be applied as a countermeasure to reduce the absorption of heat in pavement in other countries that experience hot weather."
NEC opens its first Advanced Centre for Experimentation (ACE) in Singapore, aiming to facilitate the company's global Research & Development capabilities.
ACE is strategically located in Singapore and is a key component of NEC's growth strategy in the Asia Pacific region. It leverages NEC's core technologies and advanced solutions, such as artificial intelligence (AI) and ICT platforms, thereby creating new value and contributing to a safer smarter living environment for people and communities.
NEC is investing more than S$100 million in the Asia Pacific region over the next five years, and the set-up of ACE in Singapore will be the heart of this investment: to innovatively help governments and enterprises across the region in their digital transformation journey.
