The reduction of power consumption in a building can have significant effects on financial assets, security, environmental quality, comfort, energy costs and profits. But the fact is, there is still a long way to go in efforts to reduce the amount of energy that is wasted, particularly in commercial properties such as office buildings, hotels, factories, shopping centers, education centers, hospitals and airports. The amount of energy wasted in heating and cooling accounts for a large portion of a building’s overall energy consumption. While there are global efforts to reduce energy waste and improve sustainability, building owners are still looking for ways to manage energy consumption more efficiently. As LG continues to develop innovative solutions for heating and cooling, our HVAC solutions are effective in reducing power consumption over existing HVAC systems and are able to decidedly improve the overall efficiency of a building.
Where is the Energy Being Wasted and What Can We Do?
The size and complexity of buildings continue to increase and along with that comes an increasing amount of inefficiencies that result in wasted energy and higher carbon emissions. While 30-45% of a building’s energy consumption is typically dedicated to heating and cooling, as much as 30% of the total energy consumed by a building is wasted. These statistics indicate that a significant portion of energy consumed in a building is wasted through heating and cooling. Much of this energy waste is a result of inefficient design, inefficient HVAC systems as well as inefficient system controls. Let’s take a closer look at what factors can reduce energy consumption in your building.

Keys to reducing energy consumption
1. Efficient Design
2. Efficient Equipment
3. Efficient System Control
1. Reducing Energy Consumption Through Design
This figure shows how natural lighting and ventilation reduce energy consumption in a space
If you’re planning a new building project, the design of the structure itself can greatly impact the efficiency of the building. Factors such as orientation of the building, construction materials, insulation and window type can all help to reduce energy consumption. Depending on the location of the building and the climate in the region, you can take advantage of natural heating, natural lighting and natural ventilation through placement of windows and skylights. A properly sealed building envelop can also work to prevent efficiency losses by eliminating thermal bridges in the structure. ‘Cool roofs’ or ‘green roofs’ made of materials specifically designed to reflect sunlight can even keep the roof of a building as much as 50% cooler in the summer and reduce the amount of air conditioning required. Careful consideration of these factors can make heating and cooling your building more efficient and reduce operating costs.>
2. Reducing Energy Consumption Through Equipment
While factors such as structure design and materials can reduce the energy consumption in a building, effective and efficient equipment should be a primary factor when considering an HVAC system. Finding the right solution with the specs that can meet the needs of your new or existing building while minimizing energy consumption is not an easy task. But this step in the development process is where LG can really make an impact and make your job easier.
LG Multi V 5 VRF Solutions
VRF systems allow for precise control across a wide range of spaces
Efficient HVAC systems are, as discussed, paramount to the overall efficiency of a building. The LG Multi V 5 is the newest installation in LG’s innovative VRF heat recovery systems with the latest in technological improvements to reduce energy consumption in your building. But how does the Multi V 5 reduce energy consumption and waste? First of all, VRF systems deliver refrigerant to indoor units without the need for duct work in a facility, which allows the outdoor units to supply refrigerant precisely to spaces only where cooling is required. One of the most impressive features of the Multi V 5 is Dual Sensing Control, which evaluates indoor and outdoor conditions including temperature and humidity to precisely determine parameters and further reduce energy wasted on unnecessary operation. These elements alone are doing their part to reduce waste in a building’s HVAC system and curtail the overall energy wasted in a building, but LG HVAC solutions offer much more.
LG offers a diverse set of chillers for every installation environment
Large structures and facilities such as factories and commercial buildings can generate large amounts of heat and keeping these spaces cool requires a lot of energy. HVAC systems known as chillers are essentially massive air conditioners that generate chilled water in order to provide cooling and remove excess heat from buildings. Chillers come in wide variety of configurations and they are able to utilize methods such as evaporative cooling, geothermal applications or even ice energy storage to offer energy efficient alternatives to what many of us consider conventional HVAC systems.
LG Chillers
As part of the LG total HVAC solution, LG Chillers add another level of energy efficiency in large-scale projects such as factories, power plants, district cooling and high rise buildings. LG offers a wide range of centrifugal, absorption, screw and scroll chillers that are also ideal for shopping malls, commercial buildings, hospitals or other large complexes. LG’s range of chiller solutions is able to efficiently supply coolant throughout large-scale facilities 24 hours a day. The powerful centrifugal chillers provide some of the world’s highest efficiency ratings. This diverse set of chillers provide efficient cooling and heating solutions for all types of large-scale building projects and can work seamlessly with Multi V 5 VRF systems.
3. Reducing Energy Consumption Through Control
Innovative designs and equipment play a valuable role in improving the efficiency of an HVAC system, but effective energy management used in conjunction with an efficient VRF system makes all the difference in isolating and preventing energy waste. Energy consumption in buildings makes up about 40% of global energy usage and a large percentage of this energy is wasted through ineffective energy management. Finding just the right control solution for your HVAC system can be a challenge, but LG has you covered here as well!
LG AC Smart 5
LG AC Smart 5 streamlines energy management for optimal efficiency
The intuitive AC Smart 5 control interface provides you full control of HVAC system energy management by allowing you to customize operations across facilities and floor plans from one or multiple locations and devices, and streamline operations. Comprehensive smart scheduling and analysis offered by AC Smart 5 also allow precise control of the Multi V system. With these advantages, a building manager can program the system to heat or cool spaces only when required and eliminate energy wasted in spaces that are unused or that require diverse operation loads throughout an entire building. Integration of LG’s AC Smart 5 completes the total HVAC solution for an efficient building or facility.
Even though the demand for heating and cooling is growing, LG HVAC solutions are reducing energy consumption and energy waste in buildings around the world. There are many options to consider when developing a building and while initial design and installation investments may seem high, those initial costs can be recouped in the long run with efficient designs, equipment and system controls for your HVAC solution. Consider the amount of energy your building might consume and imagine how LG VRF, chiller and control solutions can reduce energy consumption in your building as well!
