8 Actions to Improve Energy Efficiency In Heating Systems

Energy efficiency of heating systems In many buildings, HVAC is the first or second item in terms of energy costs. This technical article deals with optimisation tips and energy efficiency savings in heating systems of a building. Heating systems in building Heating systems have always been used when the outside temperature drops below a certain […]

Wiring practices to provide future load growth in buildings

Electrical wiring practices in buildings Electrical wiring is often installed without consideration for how the use of the space may change over time, particularly in residential building. This article recommends wiring practices that meet the NEC and provide for future flexibility and load growth in residential and nonresidential buildings. Let’s talk about wiring practices regarding the […]

Identify these 4 things and lower facility’s electricity bill

Electricity bill and energy losses // The world is more energy conscious these days. But unlike you, most of the world doesn’t pay electricity bill that rivals the cost of a four bedroom home. You understand the need to know where energy is being expended in your facility and how you can make it more […]

5 Factors That Mess Up Motor Efficiency and How To Improve It

Motor efficiency vs Energy losses It must be emphasised that the standard electric motor is already a very efficient device with efficiencies above 80% over most of the working range, rising to over 90% at full load. However, because of the high energy consumption, and the very large number of installed units, even a small increase […]

7 Key Steps In Lighting Design Process

Structured Design Process // To achieve the best overall outcome in a lighting installation, it is important to avoid the tendency of rushing straight into luminaire selection before determining more broadly what is required from the system. The use of a structured design process helps to avoid this. The key steps in the design process […]

7 Energy-Efficiency Improvement Opportunities In Lighting System

Lighting in industrial facilities There are a lot of opportunities to optimise lighting system in (almost) any industrial facility. Seven practical energy-efficiency opportunities to reduce energy use cost-effectively are given below: Lighting controls Replace T-12 tubes by T-8 tubes Replace mercury lights with metal halide or high pressure sodium lights Replace metal halide (HID) with high-intensity fluorescent […]

11 Energy-Efficiency Improvement Opportunities In Compressed Air Systems

85% of energy lost as waste heat… Instrumentation consumes large amounts of compressed air at many individual locations in a textile plant, but these uses are susceptible to leakage. Most such leaks are at: Threaded connection points, Rubber hose connections, Valves, Regulators, Seals, and in old pneumatic equipment. Air leaks from knitting operations are very […]

Maintenance of Electrical Equipment In Buildings

Purpose of Maintenance Apart from safety, maintenance is needed to keep plant in an acceptable condition. Maintenance of this kind must be reviewed on an economic and energy efficiency basis. While it is appreciated that breakdown of plant may result in costly interruption of normal building operation, it must also be borne in mind that […]

3 Lighting Essentials You Can’t Deny

Light Control / Energy Savings Lighting systems in industrial facilities can represent an attractive savings opportunity, especially if lighting systems have not been upgraded or maintained in the past five years. The most cost-effective approach for lighting energy savings is to address the following three issues, in order: Turn off lights during times when they are not […]

Good Voltage Regulation and Justified Power Factor Correction

Commercial Building Case Power factor correction and voltage regulation are closely related. In many cases, the desired voltage regulation is costly to obtain. Larger or paralleled conductors to reduce voltage drop under load are, in many cases, the proper solution. However, power factor correction may also be justified for four reasons: To improve voltage To […]
