Smart HVAC

Published:  30 November, 2018

There was a time many years ago that digital control was considered a strictly industrial concept, existing as a means of improving process speed and efficiency to increase throughput and output. However, smarter technology has changed the value and appeal of this type of automation. It’s no longer just about the output, but the outcome.

The changing nature of automation has made it more attractive to facilities managers, who can now incorporate it into their buildings to reap similar benefits to their industrial counterparts. Because the concept of building automation covers everything from internet-connected security systems to smart lighting, we can take inspiration from industry to see how facility managers can use automation to uncover savings.

Monitor outcome, not output

Most commercial facilities don’t have a unit of production output that can be directly influenced by automation. Yet interestingly, an increasing number of industrial businesses are focused on controlling their expenses and resources.

Energy usage is a prime example of this, and it’s one that facilities managers should also focus on. According to statistics from the European Commission, buildings contribute approximately 40% of annual energy consumption across the EU. In comparison, 2015 figures highlighted that industry uses approximately 25% of all electricity in the EU.

Facilities managers can reduce energy usage with building automation by implementing smart HVAC systems, which can regulate energy usage based on inputs - such as whether the room is in use or not. Combining this with a building energy management system (BEMS), such as those designed and delivered by the team at JMartans, allows for greater control over costs and insight into use.

Start from the top

One of the most effective lessons that facilities managers can take from industry is the importance of top-down automation. This means having a structure in place so that individual automated systems can collectively add value by being centrally controlled.

For example, many industrial businesses use equipment sensors and enterprise resource planning (ERP) systems to manage and monitor factory processes and equipment performance. Facility managers can replicate this using a computer-based system that provides this functionality in buildings.

A building automation system (BAS) is one such system, which effectively operates as a central control point for individual facility systems, such as air conditioning units and security networks. The controllers of these devices can be interconnected in a tiered direct digital control (DDC) system architecture, where facility managers and building technicians can view and control a building from one entry point.

In practical terms, this would mean facilities managers could regulate the usage of HVAC equipment and control lighting from a remote location, keeping the energy usage under control for a greener facility.

These are just a couple of automation lessons that facility managers can take from industry. As smart technology develops and extends what is possible with automation, we will see more similarities in the way these sectors operate. For now, the most effective way to see what your facility can achieve with automation is to consult with a building automation expert and develop a bespoke system that meets your needs.
