Why good HVAC and control systems save money long term

It’s common to think of HVAC (heating, ventilation, and air conditioning) as a single concept, requiring control systems for energy efficiency.



As a company with a proud history of combustion engineering, we know all about boilers. But in modern commercial buildings, cooling and air-flow are often as important as heating. The amount of IT equipment on site produces large amounts of waste heat. What’s more, building design often means that windows can’t be opened, and airflow must be controlled by technology. And as the seasons turn, summer temperatures can mean that buildings get uncomfortably warm. As a result, it’s increasingly common to talk about heating, ventilation, and air conditioning (HVAC) as a single concept. In this blog, we’ll look at HVAC and making sure your building has the right control systems in place.


HVAC is a single system that needs to work together

For many businesses, the different elements of HVAC can operate in opposition to each other, rather than working coherently. For instance, some areas in a building may be being heated while others are cooled, without proper zoning between the various areas. Of course, we can design, test, and install HVAC systems for any building, whether it’s brand new or is an older design. But we also recognise that right now, most organisations are not thinking about installing new equipment. We can devise a planned preventive maintenance schedule to keep all the equipment operating at peak condition.


Take for instance the air handling unit (AHU), the central element which regulates and circulates air. The AHU takes in outside air, reconditions it and supplies it as fresh air to the air-conditioned room. It does so by filtering, and either heating or cooling it. Even if we haven’t designed your entire HVAC system, we can install, test and commission an AHU should you need one. And our maintenance engineers will keep the unit working by putting together a maintenance schedule.


State-of-the-art control systems for 21st-century facilities management

There are many organisations where different parts of a building should ideally be at different temperatures. For instance, in an office block, corridors and reception areas should be kept cooler than workspaces. Similarly, in a hotel, recommended temperatures are 19-21 degrees C for guest bedrooms, and 26-27 degrees C for guest bathrooms. And this needs to be done in a way that responds to the building’s occupancy throughout the week, both on weekdays and weekends.


However, temperature is only one aspect of control systems. Some organisations are in a position to adopt a more comprehensive building management system (BMS) for their buildings. With modern technology, it’s possible to monitor and manage the mechanical, electrical, and electromechanical services across a facility. Such services can include power, heating, ventilation, air-conditioning, physical access control, pumping stations, lifts, and lights. A single system can consolidate the data for these controls onto a single display to improve reporting, information management and decision-making. And it allows facility-wide insight for better performance by controlling all underlying systems from a single workstation.


Whatever the demand for HVAC, think energy efficiency

Again, implementing a full-blown BMS system is simply out of reach for many organisations in current circumstances. But there are other control systems that will deliver medium- to long-term energy usage reductions. For smaller premises, a compensator automatically regulates heating temperature based on outside conditions, while an optimum start controller learns how quickly the building reaches the desired temperature. These would work well in a hotel or an office block respectively. For even smaller operations, a simple timer switch can help maintain the right temperature. For instance, in a small retail business, it can cover times when staff members are replenishing stock outside regular opening hours.


We take great pride in our maintenance services, which are just as essential as designing, installing, and commissioning a system. We can help save organisations money; poorly configured HVAC control systems can account for a significant proportion of building energy usage. Our maintenance team can ensure that the system continues to work at its peak efficiency throughout its life cycle. We will work with you to ensure that the system is configured for your building. And ultimately, we’ll improve energy efficiency and help achieve long-term carbon reduction goals.
