In recent years, with the rapid development of new technologies such as Internet, big data, cloud computing, IoT and AI, smart office has been optimized in the direction of low carbon, comfort, safety, efficiency and convenience.

 

Therefore, Serbijagas, a leading state-owned company founded in 2005 and engaged in the distribution and trade of natural gas based in Novi Sad, chose HDL smart solutions for automation upgrading, in order to save energy and reduce emissions on the one hand, and to improve the office environment for occupants on the other.

 

 

Smarter Automated Lighting Control

In this 8-story office building, HDL has installed nearly 300 motion sensors both in the corridors and office areas for smarter automated lighting control. When the sensor detects that no one around for a long time, the system will automatically dim or turn off the lights to reduce costs; and then automatically turn the lights back to normal setting when someone approaches.

 

 

In the corridor area, the automation system is able to accurately detect the illumination conditions around and human motions by sensors, which can meet the actual lighting needs without causing unnecessary waste. For instance, in the well-lit daytime, the lights will not be switched on when people pass by while lights will be automatically activated when the brightness level falls below a preset level, so that people can easily move without have to think about turning lights on or off.

 

Greener Constant Lighting

Occupants spend at least one third of their time every day in the office so the lighting in the workplace, to a certain extent, affects their performance such as working status, efficiency and creativity.

 

The company’ growth requires better workplace in order for the employees to feel motivated. By combining sensor, curtains and lighting devices, the HDL automation system maximizes the use of natural light to automatically adjust and keep the office illuminance within a constant range without human intervention, which is beneficial to make a greener and more comfortable workplace to ensure employees’ physical and mental health for higher productivity, and at the same time achieve energy saving.

 

 

Automatic Air-conditioning System

Air conditioning and some related spending account for 40% of the building's energy expenses. In the automation upgrading solution of Srbijagas office building, HDL team comprehensively considers the temperature of office building and the humidity of air circulation duct in the logic control of water-cooled air-conditioning automation system.

 

With HDL air conditioning control modules, the system will automatically select the perfect fan speed and mode based on the comparison between the preset temperature and the actual ambient temperature to achieve energy efficiency. When the air humidity is greater than a certain value of relative humidity, the air-conditioning connected to the system is adjusted to reduce the air humidity in time and maintain the space in a stable and comfortable condition, working with the fan coil, fan, cold water switch valve, extractor and resistor.

 

 

Besides, with magnetic contacts in each window, the fan coil automatically turns off to avoid unnecessary energy loss when the system detects that a window has been opened.

 

One-step Scene Control

The HDL automation system provides occupants in Srbijagas office building with one-step management of multiple devices through the setting of scenes linkage and the simple operation greatly enhances the working efficiency. One of the most popular features for occupants is the "Presentation Time" scene clicked by a single button, where the main lights in the conference room dim, the shutters slowly come down, and the projector screen come out of the ceiling.

 

 

Convenient Control Modes

In addition to automatic control of the devices connected to the system, other control modes such as panel control are also convenient. In the office building, occupants can easily control the lighting, curtains and air-conditioning through the Tile Series Panels, iTouch Series Panels and Enviro Touch Panels, as well as HDL ON, a mobile app to remotely control devices connected to the automation system.

 

 

To be a competitive company needs to reduce costs and save energy while maintaining sustainable growth, so it is great choice for a company to use automation system to meet those requirements and improve an atmosphere necessary for a good working environment.
