Ensuring Indoor Air Quality during Occurrence of Haze
- The Building and Construction Authority (BCA) requires buildings to follow Singapore Standard SS553 for air-conditioning and mechanical ventilation, but after completion, building owners are responsible for operation and maintenance.
- During the haze, building owners were advised to monitor indoor air quality, minimize outdoor air intake, and maintain filters more frequently, but there are no specific regulations or enforcement steps by BCA or NEA during haze periods.
- A multi-agency review is underway to assess if current codes need refinement, but any new measures would depend on technical data to ensure they are implementable and measurable.
