A large consumption share is falling on the commercial sector, with the rapidly expanding construction domain actively erecting malls, hotels, office buildings, and other commercial buildings that require HVAC systems.

HVAC systems are also being implemented in the industrial sector, in particular in productions and warehouses. But speaking about tendencies, HVAC solutions in the industrial domain are expected to experience a sluggish growth rate as upgrades and replacements are conducted rather seldom.

HVAC systems directly impacting climate change

With changing weather conditions, HVAC systems are becoming more and more popular among homeowners. To date, they are being utilized in almost every home.

But still, despite being deeply integrated into our daily lives, HVAC systems are causing some serious problems. More precisely, such solutions are increasing energy waste and emissions, thus contributing to pressing environmental issues.

Energy consumption

HVAC products, if not properly designed, installed, calibrated, and operated, can impact energy consumption. Talking about business operation, high consumption might cause increased expenses, reduced efficiency, customer dissatisfaction, and respectively low competitiveness.

The reasons for increased energy consumption are typically:

• Inefficient equipment

HVAC solutions that are poorly designed, installed, calibrated, or operated, are vulnerable to malfunction (temperature and humidity fluctuation, clogged filters and coils, motor failure, refrigerant leaks, and more), which increase energy waste.

• Manual operation

HVAC solutions that lack smart controls work steadily regardless occupancy, indoor or outdoor temperature, which increases energy waste.

Greenhouse emissions

HVAC products, in particular obsolete and malfunctioning equipment, can impact environmental conditions. Speaking about business outcomes, increased emissions might cause compliance burdens, limited potential, reputational and financial losses, and more.

The reasons for increased greenhouse emissions are typically:

• Fossil fuels

Furnaces, boilers, backup generators, absorption chillers, and other utilized equipment are using fossil fuels, which release greenhouse gasses when burned.

• System leaks

Inaccurate inspection and operation might cause ductwork and refrigerant leaks, which release chemical waste directly into the atmosphere.

Making your HVAC system more sustainable 

If modernized to minimize energy consumption and emissions, HVAC systems can become more sustainable. Approached appropriately, innovative technology reduces expenses, increases efficiency, and accelerates consumer comfort.

But putting theory aside, here are some ways to improve HVAC sustainability by providing software or light hybrid solutions (without replacing current hardware):

• Smart controls
• Energy analysis and reporting
• Demand response
• Predictive maintenance

From building smart controls to applying predictive maintenance, HVAC systems require accurate data analysis. Computational technology can accelerate data collection and processing, accordingly providing valuable insights and improving overall performance.

There are several ways to manage HVAC data in real-time:

• Building Automation Systems (BAS)

BAS solutions are used to monitor and control HVAC systems and other household systems (lighting, security). Such software might help gather data, identify trends and issues, provide alerts on anomalies, and respectively optimize overall energy consumption.

• Internet of Things (IoT)

IoT solutions are usually integrated into HVAC systems to collect control parameters (temperature, humidity). Such software can be easily integrated with other household systems to provide better analysis and control.

• Edge computing

Edge computing means processing gathered data at the network edge, rather than at the centralized server. Speaking about HVAC modernization, edge computing can help instantly analyze collected data in real-time, thus improving response times and latency. 

• Machine learning

ML algorithms can process sensor data to identify those patterns and anomalies that indicate potential issues. Speaking about HVAC improvement, ML algorithms can help continuously analyze collected data in real-time, thus minimizing environmental damage and preventing sudden breakdowns. 

Data storage

When selecting the database for storing and processing collected data, there are multiple factors to consider. These include business needs, project requirements, storage capacity, scalability, flexibility, and performance.

Speaking about HVAC systems, the databases available are:

• Relational databases (MySQL, PostgreSQL, and Oracle)

These databases are the most useful when dealing with data with clear, defined schemas that must be queried or joined, where consistency and integrity are of great importance.

• Time-series databases (InfluxDB, TimescaleDB, and OpenTSDB)

These databases are the most useful when dealing with voluminous, time-stamped data, which requires efficient storage, where speed and performance are of great importance, as they offer functions for handling time-series data.

• NoSQL databases (MongoDB, Cassandra)

NoSQL databases are best-suiting when handling unstructured or semi-structured data, which doesn’t fit into rigid schemas, where there’s need for flexible structures.

• Cloud-based databases (Amazon Web Services, Google Cloud Platform)

Cloud databases, which provide automatic scaling, built-in analytics, and integration with other cloud services, are best-fitting when handling time-series data, where scalability and cost-efficiency are of great significance.

Data analysis

Data analysis and presentation are crucial to tracing current processes and planning future improvements. More precisely, data management notably accelerates issue detection, timely response, energy optimization, and maintenance.

Back to HVAC systems, data analysis and presentation are performed in accordance to the following algorithm:

• Data cleaning and visualization – removing errors, incomplete information, and duplicates
• Statistical analysis – providing insights into relationships between data
• Predictive analytics – identifying patterns, potential issues, and trends
• Advanced reporting – presenting clear, concise results

Integrated alerts

Built-in alerts can help quickly identify and resolve emerging issues, making the HVAC system more sustainable. This eliminates unjustified expenses, heavy workloads, energy waste, and other serious problems.

Correctly configured, built-in alerts might help to address:

• Temperature fluctuations

Temperature alerts can notify facility managers about the temperature levels going beyond determined limits. By receiving those alerts, the recipient can adjust the system, eliminating potential energy waste.

• Humidity fluctuations

Humidity alerts can notify facility managers about the humidity levels being outside of the determined range. By receiving timely alerts, the recipient can adjust the system, eliminating poor air quality.

• Dirty air filters

Dirty filters might burden air inflows making the HVAC system work harder causing overheat and breakdowns. The alert can be set up to notify facility teams about required filter replacement.

• Dirty condenser coils

Dirty coils can entangle air venting making the HVAC system work harder causing inefficiency and malfunction. The alert can be set up to notify facility teams about required coil cleaning.

• Motor failure

Motor malfunction can cause reduced airflow, energy waste, system overheating or even complete shutdown. An alert can help to address motor failure, thus improving system performance and reducing energy waste.  

• Refrigerant leaks

Refrigerant leaks might provoke deficient performance, energy waste, equipment and environmental damage. An alert can help to handle refrigerant leaks, thus optimizing system efficiency and reducing energy loss.

Occupancy sensors

Temperature, humidity, and airflow are essential, but not the only control parameters to monitor and control. Occupancy sensors can provide additional benefits, making the HVAC system more energy-efficient.

HVAC providers might trace human presence by utilizing:

• PIR sensors that detect infrared radiation being emitted by objects, including humans
• Ultrasonic sensors that emit sound waves that bounce off objects and return back to the sensor
• Microwave sensors that emit radio waves that bounce off objects and return back to the sensor
• Image sensors that convert captured light into an electrical signal to recognize visual information

Image sensors are the most accurate but raise privacy concerns and may be subject to strict protection rules. To eliminate court proceedings, reputational damage, financial losses, and other unpleasant consequences, gathered information is to be anonymized and processed in compliance with applicable protection regulations.

Passive infrared, ultrasonic and microwave sensors are not that accurate but do not cause additional issues. These sensors do not collect personal identifiable information, which means they might be implemented without utilizing privacy-enhancing technologies.
