Duct Leakage Test
Introduction to Duct Leakage Testing (DLT)
HVAC systems are the lifeblood of any commercial building, so it’s crucial that they be always functioning properly. One way to ensure this is by performing duct leakage testing (DLT), which checks for any air leaks in the system.
DLT is important for two main reasons: first, because it can help improve energy efficiency by reducing the amount of air that escapes through leaks; and second, because it can help improve indoor air quality by preventing outside contaminants from entering the building through those same leaks.

Benefits of Duct Leakage Testing for Buildings
As building energy codes have become more stringent, the requirements for ductwork have changed. In addition to being well-sealed and insulated, ductwork must now be tested for airtightness.
Duct leakage testing is a way to measure the airtightness of your ductwork and ensure that it meets the requirements of the code.
Duct leakage testing has several benefits for buildings, including:
Improved energy efficiency:
Ducts that are properly sealed and insulated can improve the overall energy efficiency of a building by reducing the amount of conditioned air that is lost through leaks.
Reduced utility costs:
By improving the energy efficiency of your building, you can also reduce your monthly utility bills.
Fewer repair and maintenance issues:
Buildings with properly functioning HVAC systems often experience fewer repair and maintenance issues because there is less wear and tear on the equipment. Additionally, buildings with good indoor air quality tend to have fewer sick days and absenteeism among employees.
Improved indoor air quality:
Properly sealed ductwork can help to improve indoor air quality by preventing outside contaminants from entering the ductwork and circulating throughout the building. Additionally, sealing ductwork can also help to prevent moisture buildup, which can lead to mold growth.
The Importance of Duct Leakage Testing in Buildings
Ductwork is one of the most important aspects of any HVAC system, and it is essential that it be properly sealed and maintained to ensure optimal efficiency.
Duct leakage testing is a critical part of keeping ducts in good condition, as it can identify areas where the air is escaping and investigate the cause of the problem.
There are many benefits to having regular duct leakage testing carried out on your building’s HVAC system. Firstly, it can help to improve the overall efficiency of the system by ensuring that air isn’t being lost through leaky ducts.
Secondly, it can help to reduce your energy bills by ensuring that your HVAC system isn’t working harder than necessary to maintain comfort levels. Thirdly, it can help to prolong the life of your HVAC equipment by preventing premature wear and tear caused by excessive heat loss or gain.
Duct leakage testing is typically carried out using a calibrated fan pressurization technique, which involves using a fan to pressurize the ductwork and then measuring the amount of air that leaks out. This provides an accurate measurement of the ductwork’s tightness and allows for any leaks to be located and repaired.
The Selva Group offers comprehensive duct leakage testing services for both commercial and residential buildings in Dubai. Our team of experienced engineers will carry out a thorough examination of your ductwork and provide you with a detailed report outlining any areas of concern.
What should you do before Test and Commissioning?
Before you begin the test and commissioning process, there are a few important things you should do to ensure that the process goes smoothly. First, you should make sure that all the necessary equipment is on hand and in good working condition.
This includes the ducts themselves, as well as any fans or other ventilation equipment that will be used during the testing process. Next, you should take some time to familiarize yourself with the ducts and the testing process.
This will help you to identify any potential problems before they occur. You should develop a plan for how you will conduct the tests and what criteria you will use to determine whether the ducts are functioning properly. Once you have done all these things, you will be ready to begin the test and commissioning process.
What is the Process of DLT?
Duct Leakage Testing, or DLT, is a process of testing the airtightness of ductwork to ensure that the ductwork is providing the proper level of ventilation for a space. The test involves sealing all openings in the ductwork and then pressurizing the system.
The pressure within the system is then measured to determine if there are any leaks present. If leaks are found, they can be repaired, and the system retested until it meets the required standards.
What are Quality Indicators in Client Building or Facilities?
There are many factors that affect the quality of a building or facility, but one of the most important is the ductwork. The ductwork is responsible for transporting air throughout the building, and if it is not properly sealed, it can result in a significant loss of energy and money.
To ensure that your ductwork is sealing properly, you need to have a duct leakage test performed. A duct leakage test is designed to measure the amount of air leakage through the ductwork. This test is important because it can help you determine if your ductwork needs to be repaired or replaced.
If you have a high degree of leakage, it may be time to invest in new ductwork. However, if you have only a small amount of leakage, you may be able to simply repair your existing ductwork.

Common Challenges Behind Duct Leakage Testing in UAE
There are several reasons why duct leakage testing is so important for buildings in the UAE. The first reason is that it helps to improve the indoor air quality of a building.
The ductwork that is not properly sealed can allow outside air to enter the building, which can contain pollutants and other contaminants. By conducting a duct leakage test, you can ensure that your building’s ductwork is properly sealed and that indoor air quality is not compromised.
Another reason why duct leakage testing is so important for buildings in the UAE is that it can help to save energy costs. Buildings with poorly sealed ductwork often must use more energy to maintain comfortable indoor temperatures.
This wasted energy translates into higher utility bills for building owners and occupants. Duct leakage testing can help reduce energy costs by ensuring that ductwork is properly sales and that energy is not being wasted.
Duct leakage testing is also important for safety reasons. Poorly sealed ductwork can allow explosive gases to enter a building, posing a serious safety hazard. By conducting a duct leakage test, you can ensure that your building’s ductwork is properly sealed and that there is no risk of an explosion.
As building envelope and energy performance consultants, we often get asked about duct leakage testing and its importance in relation to a building. Here, we offer some valuable insights into the ductwork, duct leakage testing, and how it can impact your building’s energy efficiency.
Ductwork is the system of channels and pipes that circulate air throughout a building. It is essential for proper ventilation and climate control. However, over time, ductwork can develop leaks. These leaks can be caused by a variety of factors, including poor installation, age, and wear and tear.
Duct leakage can also occur when connecting different types of ductworks together. Duct leakage results in wasted energy as well as reduced comfort levels in a building. In fact, studies have shown that up to 30% of the air that is circulated through ductwork is lost due to leaks.
This wasted energy not only drives up utility costs, but also contributes to greenhouse gas emissions. In the UAE, where summers are extremely hot and humid, properly functioning ductwork is especially important in maintaining comfortable indoor conditions.
Fortunately, there is a way to test for duct leakage: a process called duct leakage testing (DLT). DLT involves using a calibrated fan to pressurize or depressurize the system and measuring the airflow through any leaks that may be present. The results of the test are then used to help seal the leaks, improving the overall efficiency of the ductwork system.
