Creating the Building Automation System for One of Indonesia's Largest Shopping Centers

Designing and implementing the building automation system for the Karawaci Supermal was a success, thanks to MOSCADS and their InduSoft Web Studio solution.

 

MOSCADS Case Study
  • InduSoft Web Studio was used to create a building automation system for Karawaci Supermal in Jarkarta, Indonesia.
  • The application  controls the scheduling of the building’s energy use, as well as monitoring systems all over the facility.
  • The savings of energy consumption costs have been substantial since the new system was developed, and managers and operators can view data from all over the facility and make quick changes or provide preventative maintenance.

Managing the many systems that make up a huge ecosystem of buildings is a challenging task. Luckily, as better tools are built and designed, any building automation project can be improved. Greater control of aspects of the system such as energy use, heating and cooling, HVAC systems, and even security leads to a more efficient building complex that can manage resources in the most cost effective way possible.

 

Karawaci Supermal, Located in Jakarta, Indonesia, is one of the largest family shopping centers in Indonesia. With the help of MOSCADS, the entire building automation system of the mall was overhauled with a building management system based around InduSoft Web Studio, providing huge cost savings benefits.

 

Background 

Karawaci Supermal is a massive structure that occupies nearly 12.5 acres of land in Jakarta, Indonesia. The building complex includes nearly 200,000 square feet of space, and consists of a compound divided into sections dedicated to certain types of retail spaces, from cinemas to department and hardware stores. The mall sustained looting and burning in a series of riots in 1998, and reopened under the name Lippo Supermall. Since then, the mall has continued to expand. In 2006, phase two of the supermall was opened to the public to offer a vast shopping experience.

 

Throughout these changes, operators of the building management system in the mall were in charge of operating the various systems, which included turning on and off electrical systems, air conditioning, and more. This was an inaccurate and inefficient system, as operators had to move to different areas of the facility to address different aspects of the system. Schedules were often missed, which could cause huge increases in costs.

 

The owners of Karawaci Supermal decided to invest in a building management system that could not only control and monitor the building using robust and reliable software, but also provide an informative graphical interface for operators to use.

The Challenge

MOSCADS stepped in to accept the challenge of developing a system that could control and monitor the whole building complex, including: the cooling tower, exhaust and intake fans, water pumps, circulation pumps, fire pumps, lighting, the high voltage transformer, the generator, and the temperature and air quality monitoring equipment.

 

Scheduling proved to be a big problem for the non-automated system. The system was most efficient when operators kept to a tight schedule that required turning systems on and off with precision timing. For example, the schedule might call for a fan to turn on a 9:55, and then the compressor to come on five minutes later, at 10:00. However, if operators were in that section of the facility, they might turn on both as 9:45 before moving to another room. While this made things easier for operators, it was far from efficient. In order to control costs, developing a schedule and automating equipment would be critical.

 

The building management system that the Karawaci Supermal required would be a new project designed from the ground up. This gave MOSCADS complete freedom to explore the top SCADA and HMI development platforms and choose one that best suited their customer’s requirements.

 

MOSCADS chose InduSoft Web Studio and developed a demo application to show to the client. The demo won over owners and operators because it was simple to use, and supported the unique demands of the mall’s building automation system.

The Solution 

The application built using InduSoft Web Studio connects to a variety of equipment using the Modbus/TCP protocol, and allows operators to access the system from across the facility using sixteen Web Thin Clients, with email functions that send out messages if an alarm occurs. The application monitors and controls the entire building automation system of the mall, and the remote viewing capabilities provide data to operators and the Supermal Karawaci management team all over the building.

 

Scheduling is controlled with the system, and protected through InduSoft Web Studio’s security features. Because of the costs associated with improper schedule adherence, the system security is divided into levels of access protected by usernames and passwords. Operators may monitor and start or stop equipment, but only the building maintenance manager can change the schedule. Mall management and other authorized uses can view the data remotely, but not control the equipment.

 

The system controls everything from the energy use to the water pumps and airflow of the mall. The flexible nature of InduSoft Web Studio makes it possible to connect to a variety of hardware using common communication protocols that are included with the more than 240 drivers, such as BACnet that are built into the SCADA/HMI software.MOSCADS Case Study

 

The Results

The main result of the installation of the new InduSoft project and user interface has been the money saved by controlling scheduling and automating equipment. The mall has seen energy efficiency rise considerably, and saved a substantial amount on costs by better controlling the schedules of equipment use. In addition, it’s far easier to monitor aspects of the system for potential problems, or provide preventative maintenance that will continue to help the mall increase the efficiency of their building automation system.

 

MOSCADS has leveraged the success of this operation by promoting a similar HMI for use in other business divisions of the mall owners, such as the apartment developer division. The Karawaci Supermal facility is only part of a larger corporate community that offers plenty of opportunities for development of more building management systems such as those used in the mall. But why stop there? According to Steve Rion, Chief Technical Officer at MOSCADS, "We plan to install InduSoft Web Studio in every building in the country!"

 

This year, the project will be upgraded to include more than 3,000 new hardware I/O points that gather data from across the new facility from systems such as the air conditioning, cooling tower, lighting, and power. Supermal is continuing to expand, and is building new floors this year, which will require additions to the building automation project designed by MOSCADS.
