HVAC System Efficiency
People spend most of their working lives indoors. This reality stresses the importance of indoor air quality across working environments. Statistics from the National Human Activity Pattern Survey (NHAPS) show that people spend approximately 90 percent of their waking hours indoors.[1] Furthermore, the average person spends over 13 years of their life at work according to one analysis from HuffPost Australia.[2]
At the same time, advances in technology have reshaped daily life. Cities, buildings and the future workplace is dependent on smart innovations.
The evolvement of HVAC system, which is one of the key elements of building management, is on course with this trend. There are three major necessary conditions of HVAC systems; increase the productivity of employees, meet the needs of office buildings by traits, and promote both energy and economic efficiency.
Healthy air to boost up the business performance
The average person spends eight hours a day breathing air from the office. Therefore, it is clear that the Indoor Air Quality (IAQ) of the office affects business performance.
Studies have shown that productivity and indoor air quality in the office are strongly linked.[3] Comparing the performance of employees working in ‘healthy air’ to those working in ‘polluted air’, employees working in healthy air made up an additional $15,500 more per year.
Furthermore, the cognitive function was improved by 50 percent when the CO2 level in the office was lowered from the normal concentration of 1,400 ppm to 600 ppm according to a study by Harvard T.H. Chan School of Public Health.[4]
For this reason, it is crucial that offices manage the IAQ by keeping a set temperature by adjusting the wind direction automatically or utilizing a sensor to detect when no one is present and stops operation.
Customized zoning satisfying the various needs of buildings
From large office buildings to government offices and apartment-type factories in a city, modern workplaces vary in kind. Even single work environment is composed of several distinct spaces that meet the needs of various kinds of work. Therefore, flexible offices should be able to apply HVAC systems optimized for orientation of the building and interior space characteristics.
Maximized energy and cost-efficiency
Advancements in HVAC systems can help building owners save energy by predicting future energy consumption.[5] For instance, CIBIS Tower 9, a landmark and LEED® Platinum- certified building in Jakarta, was deemed a highly efficient air conditioning system that could reduce operating energy. The building chose the best solution by simulating and comparing energy consumption before installation.
Also, CIBIS Tower 9 could save the cost with the support from design, development and construction stage. As the building introduced the total HVAC solution, the tenant can benefit from smooth maintenance service. Moreover, an accurate billing system for each space helps to prevent the unnecessary cost.
LG’s customized HVAC System for the office
LG Electronics (LG), a world-renowned home appliance & HVAC company, has released a line of customized HVAC systems to improve the efficiency and bring down the TCO (Total Cost of Ownership) of the office. The company has introduced the Multi V series to provide the benefits of Variable Refrigerant Flow (VRF) to office buildings.
To improve the working environment in the Middle East, LG offers Multi V Air Handling Unit (AHU) and Multi V Dual Vane 4 Way Cassette. Multi V AHU, providing ventilation with cooling and heating, maintains a constant CO2 concentration to provide pleasant indoor air. Multi V Dual Vane 4 Way Cassette adjusts the temperature of both direct and indirect wind to create a comfortable and efficient working environment. Plus, the cassette provides clean air with LG’s advanced air purifying kit and panel which achieves Clean Air Delivery Rate (CADR) of 692.2 ft3/min.[6]
LG’s HVAC system benefits consultants with products considering space characteristics. With one outdoor unit, Multi V 5 can operate both cooling and heating at the same time. For example, Multi V 5 can provide cooling in a computer room and a communication device room with a high heat output while simultaneously provide heating in general office rooms. In this way, the flexible, functional and multipurpose needs of the building could be satisfied.
Also, LG provides great support and service throughout and after the installation which is a great help to both building owners and consultants. Moreover, LG offers “Energy Simulation Analysis” to help customers compare energy consumption. Furthermore, customers are able to get timely technical support and onsite training for the installation team.
“As the industry evolves, offices and HVAC systems are undergoing a vital transformation,” says Mr. Suraj Kumar, Technical Manager-Air Solutions, LG Electronics Gulf. “LG Multi V is an efficient VRF with great flexibility. It is the best solution for offices that prioritize user comfort.”
