Watch out for the breaking news happening in the industry and SGBC’s latest developments.


This Guidance Note serves to provide precautionary measures for building operations to reduce the risk of disease transmission and minimise the build-up of chemicals from cleaning and disinfection activities.

 With the gradual easing of Circuit Breaker (CB) measures after 1 June 2020, the Government is phasing in the reopening of work premises with requirements for businesses to put in place safe management measures. In line with these measures, the Building and Construction Authority (BCA), the National Environment Agency (NEA), and the Ministry of Health (MOH) are providing operational guidance for Air Conditioning and Mechanical Ventilation (ACMV) systems in buildings. Building owners and facilities managers may wish to refer to this Guidance Note for precautionary measures associated with operations of ACMV systems during the period relevant to COVID-19 situation.
