Building owners, contractors, and consulting engineers are looking for ways to improve heating, ventilation, and air conditioning (HVAC) systems. HVAC systems are energy-intensive, accounting for approximately 40% of a building’s total energy consumption, according to Australia’s Department of the Environment and Energy. This means that in non-residential type buildings, HVAC systems are major energy users.

If you want to improve environmental sustainability and reduce the operating costs of your company’s HVAC system, you should consider installing an automatic temperature control valve and following these energy-saving tips:

Turn Off the Cooling Coils in Cooler Months

The process of turning off the cooling coils when the weather is cooler is called economy cycling. You let the chiller rest and reduce its energy consumption. While it takes its break, the building takes air from the outdoors.

Optimize the Building Management System

The optimization of your building management system (BSM) can result in lower energy consumption and optimal operating conditions. You have to install smart control software, sensing software, and sub-meters.

Because of smart control strategies, the BMS can determine the best conditions in which HVAC systems can operate in. It can do so by enabling you to enhance the consumption information that each of its parts receives so that they can adjust their settings. This process, in turn, minimizes energy consumption and costs.

Capturing and Recycling Waste Energy

You can practice energy recovery to lower your system’s energy consumption. This is done by drawing heat or fresh air from exhaust air. The captured air is then recycled by using it to cool or heat the fresh air entering the HVAC system before it reaches the air handling unit (AHU). This allows the AHU to lower its energy use.

Fine-tuning Your Building

When HVAC systems are newly installed, they are highly efficient in their operations. But time can wear them out. By commissioning and tuning them, you allow them to function like they were new again. Thus, the process of commissioning and tuning a building can help you achieve energy savings.

Using the Right Plant

In HVAC systems, a plant is a room that contains the large evaporator, thermostatic expansion valve, condenser, compressor, and all the other system components. It is needed in large buildings because HVAC systems cool and heat large spaces. This is also the reason why significant parts are used.

For HVAC systems to work efficiently, they need components with the right size and load. For example, to work at its best, chillers require a particular weight, but unless the parts you install can’t produce the same load that the chiller requires, it can’t work correctly.

The size of your plant room can also affect your building’s energy use. You should build an accurately sized room to lessen the system’s impact and improve its energy efficiency.

As a building owner or manager, you can’t ignore energy costs when they start to rise. You have to do something. Follow these tips to make some energy savings in your company. And take advantage of the increasing technical innovations that can help buildings become sustainable, greener, or more energy-efficient.
