The Singapore building management system (BMS) market is forecast to expand with a 7.2% CAGR for 2021–2027. Although the positive growth over the forecast period is attributable to recovery from the pandemic, it will not reach the market size of pre-COVID-19 years. Growth is lower due to slower recovery in the construction sector until 2027. Although projects largely resume in 2021, new waves of COVID-19 infection in Singapore dampened growth in that year, and the BMS market registered a slight decline of 5.0%.

Building automation system (BAS) was the largest BMS product segment in Singapore from 2018 to 2020. In 2020, its revenue accounted for 41.2% of the BMS market and will likely record a 6.9% CAGR (2021–2027). However, energy management system (EMS) overtook BAS as the largest BMS product segment in 2021. EMS’ revenue share was 41.9% that year, while BAS took 39.1% of BMS revenue. The EMS segment is forecast to register a 7.4% CAGR from 2021 to 2027. Although emergency and security automation systems (ESAS) will remain the smallest BMS product segment throughout the forecast period, it will be the fastest-growing section at 7.6% CAGR (2021–2027).
