Smart and green urban living on the horizon (An article in Future Ready Singapore)

by

An article of our T2 lab is now live on the FRS (Future Ready Singapore) website.  You can read it from this link.

“Lau Siu Kit … explains that the idea for the T2 Lab was conceived through two driving forces: the increases in population density and energy in Singapore and the growing awareness and emphasis placed on sustainability and global efforts to combat climate change.”

“There is an increase in awareness of sustainable buildings and cities among students at the school. Globally, countries have pledged to limit global temperature rise to below 2 degrees Celsius. The T2 Lab comes at a good time, with many opportunities to establish NUS and Singapore as a leader in the area of sustainable living,” he explains.

“We want to know more about these technologies and use them well in the tropics, so that this knowledge can be transferred to the industry and general public. It is our hope that our research can benefit people living in Singapore, through energy savings and ecological improvements,” adds Lau.
