Suntec City Office Towers is embarking on a comprehensive refurbishment project that includes the replacement of existing key equipment to enhance the reliability of the Air-Conditioning and Mechanical Ventilation (ACMV) system, and the installation of an indoor air quality (IAQ) monitoring solution to improve air quality standards and enhance the comfort of tenants in the office environment.
Picking up the project, UnaBiz purportedly will together with ACMV expert, D-Team Engineering to:
- Replace the Air Handling Unit (AHU) at the plant room located adjacent to the service corridor.
- Replace the Variable Volume Air (VAV) Controller sets located within the office areas.
- Deploy close to 800 wireless IAQ monitoring sensors and 50 LoRaWAN gateways to monitor the IAQ levels of all five Suntec City Office Towers to ensure consistent IAQ standards and monitor the performance of the new ACMV systems.
According to Steven Kong, senior manager of operations of APM Property Management, the main purpose of the rejuvenation plan is to help maintain comfort and a stable temperature in all five office towers. A data-driven ACMV system ensures good air quality for shoppers and tenants, while a high energy-efficiency system helps optimise energy consumption and reduce carbon emissions.
For this project, UnaBiz will install Milesight IAQ sensors and gateways, with Actility ThingPark Enterprise on-premises IoT platform on a LoRaWAN network. The deployment will be carried out in phases starting with Tower 4, Tower 2, Tower 3, Tower, 1 and Tower 5.
In total, there are about 2.3 million square feet of office space. Tower One to Four is 45-storey representing the 4 fingers and Tower 5 is 18-storey representing the thumb.
The IAQ sensor is a comprehensive 9-in-1 solution that integrates nine types of sensors to measure various ambient conditions including CO2 concentration, temperature, humidity, light, TVOC, barometric pressure, PM2.5, PM10, formaldehyde and motion. This energy-efficient sensor is designed for real-time monitoring and collecting reliable IAQ data 24/7.
UnaBiz Singapore’s managing director, Jonathan Tan acknowledged that the COVID-19 pandemic has demonstrated to us the importance of IAQ monitoring as the majority of us spend our time indoors. By integrating indoor IAQ monitoring with the new ACMV system, Suntec City can prioritise tenant well-being, and optimise airflow and energy consumption through data-driven ventilation.
