Written Reply to Parliamentary Question
Ms Elysa Chen asked the Minister for Transport
a. whether LTA is studying heat-mitigation and air-purification solutions for open-air bus interchanges and stops, such as the cooling-cum-purifying systems previously trialled by ST Engineering, given rising ambient heat over the coming decade; and
b. whether such features could be incorporated into planned interchange renovation and upgrading works.
Reply by Minister for Transport Jeffrey Siow:
1. For thermal comfort at bus interchanges and bus stops, the Land Transport Authority (LTA) has implemented energy-efficient cooling solutions suitable for the more open nature of our bus infrastructure, including mechanical fans at bus interchanges and green roofs at bus stops.
2. LTA will continue to explore other solutions for our bus interchanges and bus stops, to improve comfort. As with previous trials, these solutions will only be deployed at scale if they are energy and cost efficient relative to their benefits.
