Pipework Thermal imaging also gives valuable information about the condition of pipe, tube and valve insulation. Inspecting the condition of the insulation material surrounding the pipework can be crucial. Heat losses due to failing insulation will show up very clearly in the thermal image, allowing you to quickly repair the lacking insulation and prevent significant energy losses or other damages. Process valves are another good example of pipework related equipment that is often inspected with thermal imaging cameras. Besides leakage detection a thermal imaging camera can also be used to determine whether the valve is opened or closed, even from a distance. Examples of pipework faults that can be detected with thermal imaging are:
- Leakage in pumps, pipes and valves
- Insulation breakdowns
- Pipe blockage
All types of leakage, blocked pipes and faulty insulation will clearly show up in the thermal image. And because a thermal image can quickly give you an overview of an entire installation, there is no need to check each pipe individually. References: Flir Systems

Introduction To Building Management Systems
A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.
Systems linked to a BMS typically represent 40% of a building\\\’s energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.
As well as controlling the building\\\’s internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
Functions of Building Management Systems
The three basic functions of a central, computer-controlled BMS are:
the building’s facilities, mechanical, and electrical equipment for comfort, safety, and efficiency.
A BMS normally comprises of:
• Power systems
• Illumination system
• Electric power control system
• Heating,Ventilation and Air-conditioning HVAC System
• Security and observation system
• Magnetic card and access system
• Fire alarm system
• Lifts, elevators etc.
• Plumbing system
• Burglar alarms, CCTV
• Trace Heating
• Other engineering systems
• Home Automation System
• Fire alarm and Safety system

Time-Lapse Graphics™ is a revolutionary new feature within WebCTRL that allows operators to roll back time, up to a 24-hour slice, and play back hours of real-time data in just minutes. This innovative feature provides a quick, visual indication of any problem areas and gives facility managers a strong diagnostic tool to quickly identify and correct issues that impact energy efficiency and comfort.
Our Environmental Index™ provides a simple and effective solution. Starting with temperature as a key component of comfort, the Environmental Index (EI), expressed as a percentage, reflects how close the zone temperature is to the effective heating and cooling setpoints. Accessed through a browser using WebCTRL, the EI is shown on an easily read analog gauge, using the red segments to indicate poor environments, and graduating to green as conditions improve and the EI begins to approach 100%.

Balancing Efficiency with Comfort
As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort. Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
