HVAC (Heating, Ventilation and Air-conditioning) is a system used to maintain and control indoor environment safe and comfortable, meaning that the air should have sufficient amount of oxygen and free of unpleasant and hazardous gases. HVAC is based on the principle of thermodynamics, fluid mechanics and heat transfer. These systems has three main components i.e. a central plant, a distribution system and a rejection unit. With the rising need for better working and living spaces the HVAC systems market is expected to grow in forthcoming future.
The growing HVAC systems market is driven significant factors like rapid industrialization, increasing population and urbanization, rising temperature and pollution across the globe due uncontrollable greenhouse and other toxic gases emission. However, high initial cost of systems and their maintenance is hampering the growth of the market. Moreover, with emerging need towards comfortable and safe indoor environment and replace old systems with more effective and efficient systems is likely to flourish the HVAC systems market.
Commercial buildings account for more than 35 percent of the total energy consumption. In most of those structures, heating, ventilation and air conditioning systems consume more than 30 percent of the total energy use.
Building owners and facility managers are challenged with getting financial returns from their investments while providing a building that is energy efficient.
As HVAC systems have become complex, non-linear and dynamic, facility managers are increasingly using building management systems to collect data about the performance of the building, as well as energy consumption by individual equipment such as HVAC systems.
1. Comfort of indoor environment
The importance of an HVAC system in commercial and residential buildings cannot be overemphasized.
The fact remains that fresh air is good for the body, and in commercial buildings, it helps improve productivity. A good ventilation system helps to reduce the number of pollutants, bacteria and odor in a facility.
Data analytics of HVAC systems helps in regulating the temperature of a building and lowering humidity by ensuring that moisture in a building is kept under control. Good ventilation systems remove breeding grounds for dust mites, which contribute to causing eczema.

2. Energy efficiency
Operating a HVAC system at optimum efficiency is a challenging endeavor. The number of set points, levels and feedbacks of boilers, chillers, pumps, fans, air delivery components and more can cause costly inefficiencies. Add to that the fact that weather variables affect the heat transfers in a building and increase loads on the HVAC.
3. Improve indoor air quality
According to the Environmental Protection Agency (EPA), poor indoor air quality is among the top factors of environmental risk. Pollutants in the air can aggravate allergies and asthma in some people and cause dizziness and headaches in others.
Air quality depends on various factors like people entering the facility, use of other equipment and presence of electronics. With the proliferation of cheap sensors, air quality data is now being accurately measured.
4. Preventive maintenance
HVAC systems often operate at suboptimal levels at least 40 percent of the time in buildings. This is due to the complexity of the buildings, as well as many moving parts like fans, pumps, air-conditioners, ventilators and dampeners.
Data analytics uncovers the following problems of your HVAC system:
Poor control settings and programming errors
Stuck dampers causing excess outside air intake
Valve leakage leading to uncontrolled supply-air temperatures
Outright equipment failure
5. Actionable insights
Data analytics provide essential insights to help with monitoring, controlling and maintaining your HVAC systems. In the absence of this type of information, facility managers physically perform manual audits that are inefficient and time-consuming.
With the advent of IoT, more sensors are being used in buildings for various equipment. The data analytics out of this ocean of data can help determine the best course of action to take to maximize HVAC efficiency.
The global HVAC systems market is segmented on the basis of heating, cooling, ventilation, implementation and application. Based on heating, the market is segmented as heat pumps and space heaters. On the basis of cooling the market is sub-segmented into room/unitary air conditioners, chillers, VRF (Variable Refrigerant Flow) systems, coolers, and others. On the basis of ventilation the market is sub-segmented into air filters, air purifiers, centrifugal fans, roof vent, ventilation fan, air handling unit and others. On the bases of implementation the market is segmented into new installation and retrofit. Similarly, based on end-user the market is segmented into residential, commercial and industrial.
