When it comes to lighting, there are five things to think about.
- Cost – Light fixtures can be costly, so check sure the numbers stack up and provide a return on investment.
- Workplace Lighting – Check lighting levels to verify they are adequate and within HSE guidelines.
- Demonstrating impact – establishing a fixed, permanent, or temporary energy metre to verify expected savings is a good idea.
- Is there any kind of guarantee? – Always double-check whether the light fixtures you’re considering come with a warranty (AES offer a 5-year warranty).
- Are they up to the task? – Light fittings with no glass must be used in a food factory, or T5 lights with food-grade shrink wrapped tubes must be used.
Over the last ten years, energy consumption has come under increased scrutiny, and businesses are becoming more conscious of their energy consumption and its impact on the environment.
We offer a free energy reduction audit of your business to assist you understand where you can make the biggest difference. A comprehensive report will be supplied, detailing energy consumption savings as well as genuine cost savings to your company that can be redirected to your bottom line. The cost savings and return on investment in energy reduction can be realised in a considerably shorter time if you have a multi-site organisation. environment.
Low Energy Lighting
More modern technologies, such as LED, T5, and induction lighting, are used in energy efficient lighting.
These goods are not only more durable (with a slower Lumen depreciation), but they are also more efficient in terms of Lumen per Watt. Furthermore, they outperform traditional lighting options such as incandescent, CFL, and halogen bulbs. The most recent products make use of an energy-efficient electrical conversion mechanism that saves energy by reducing heat waste.
Low-energy lighting will drastically cut your operational operating expenses and provide a long-term positive return on investment. Typically, these gains are realised in three to five years.
By utilising illumination only when necessary, presence/movement sensors, daylight sensors, and automated lighting can further cut operational costs. Lighting control is included in our initial site inspection to help us figure out where extra energy is being squandered.
Voltage Optimisation
Energy Efficient Motors
Electricity suppliers in the United Kingdom are permitted to deliver 230v electricity to business establishments with a -5/+10 percent tolerance. As a result, the voltage input into a firm can be far higher than necessary.
Although all equipment is designed to operate at maximum efficiency, inadequate control of the incoming voltage (and tolerances) can dramatically diminish efficiency. A 230v filament light, for example, should last 1000 hours; however, if the voltage input is 240v (still within the tolerance), it will break after 550 hours, wasting 9% more energy.
When you multiply the previous example by every single component that requires electrical input, you can see how voltage optimization can help you save money and energy.
Voltage optimization can reduce your energy use by up to 20% while also raising your maximum output by 10% and extending the life and reliability of your entire system. While some machinery in a manufacturing environment must run at a constant speed, many motor applications, fans, and pumps have varied operations. This is when a VSD comes in handy.
VSDs convert the incoming electrical supply of fixed frequency and voltage into a variable frequency and voltage output to the motor, with a corresponding change in speed and torque. Most are controlled automatically.
Variable Speed Drives
Using a variable speed drive (VSD) to slow a pump motor or fan by 20% can save up to 50% on energy. The amount of electricity consumed to meet this new requirement is greatly decreased by running at a slower speed.
Replacing obsolete plant machinery motors with modern, energy efficient motors is a crucial area where industrial, engineering, and manufacturing enterprises can achieve significant energy savings.
The ratio of the mechanical power delivered by a motor to the electrical power supplied is known as efficiency. An 83 percent efficiency ratio, for example, means that a motor converts 83 percent of electrical energy into mechanical energy while losing 17 percent – most typically through heat dissipation.
Modern energy efficient motors feature a much improved motor design, are manufactured using high-quality materials, and produce significantly less heat and noise.
