Lighting represents 20% of the total energy costs of commercial buildings and 38% of their costs for electricity, according to data from the Cleantech Approach Group (CTA). Consequently, efficient management of lighting systems can significantly reduce the mentioned costs, and one of the ways to achieve this is using smart LED lamps that support the lighting control system.
CTA points out that controlling the lighting of LED lamps is the first step toward reducing electricity consumption and saving money. However, installing such lights means higher installation costs than conventional lighting. The long-term use of LED lighting and advanced technologies that reduce electricity consumption pay off the initial investment and ensure significant savings over time. One of the ways of paying off investments is the so-called ESCO model.
The ZenQ company recognized the importance of lighting control and all the advantages that this function can have, so it offered its clients high-efficiency ZenQ LED lamps, which, in addition to high-quality lighting and control, offer other functional and aesthetic advantages.
How does the lighting control system work?
The first and critical factor for considering a potential investment in lighting control solutions is carefully examining the electricity consumption of the building or space to be lit.
Given the age and general technology used in buildings or public spaces, it is likely that there are significant opportunities to reduce energy consumption through simple strategies such as:
- maximum use of daylight,
- enabling the presence detection function and
- optimal arrangement of lamps
Electricity consumption to light industrial plants, streets, or other public facilities can be significantly reduced by achieving optimal operation of the lighting installation at any time. Lighting management is possible by choosing the appropriate equipment for automatic lighting control.
With automatic lighting control, it is possible to control groups of lamps, and some of the functions that can realize are:
- determining the brightness level,
- combination of natural and artificial lighting,
- the possibility of regulating the luminous flux of the lighting fixture (light intensity),
- detection of human movement or presence, the presence of vehicles on the streets, and more
Cost reduction with lighting control
One of the agencies engaged in research in the field of lighting estimated in 2010 that the modern world annually builds around 11.3 billion square meters of buildings. Of all types and purposes. The report also states that electricity consumption for lighting costs more than 174 billion USD per year globally. Still, they believe that could be reduced to 119 billion USD shortly, even with the increase in a built-up area.
Lighting control, which includes presence sensors, daylight sensors, and devices that can reduce the intensity of the light source or control it remotely, can reduce energy consumption by 60%, and it is estimated that soon such systems will be in about 30% of buildings.
Smart lighting control solutions enable businesses and LED lighting users to reduce the electricity costs associated with the lighting infrastructure itself. With these solutions, companies can more easily control the operation of their lighting systems and, following the activities on the premises, provide the necessary lighting when needed.
The lighting control system determines when the lights need to be turned on or off. Or when the light needs to be dimmed. That is one of the basic principles and solutions used for the concept of smart cities. In this way, excessive electricity consumption is eliminated, and the needs of employees working in that environment are met.
Saving electricity - saves money
LED lamps are made of the highest quality materials to have functions that enable savings and cost reduction by controlling lighting and, above all, electricity consumption. We present only some of the intelligent systems supported by ZenQ luminaires, which can be used in general, public, medical, sports, or industrial lighting.
Daylighting – supplementation with artificial daylight
Light control enables artificial daylight to be supplemented to an optimal level. Electricity costs are significantly reduced by maximizing daylight and reducing artificial lighting. Carbon dioxide emissions are also directly reduced with a positive impact on the performance, mood, and well-being of users of the illuminated space.
Motion sensors in lamps
In areas with a variable number of pedestrians and traffic density, such as squares, parking lots, residential areas, corridors in residential buildings, or places with little activity, the lighting can be set to a "minimum" most of the time.
Thanks to motion sensors, the lighting level can be raised when a pedestrian or vehicle is detected. The "light on demand" function increases the safety and comfort of all users while significantly saving energy and reducing the costs of LED lighting.
Photometric calculations include all data obtained by measuring the photometric characteristics of the lamps. After that, estimates are converted into forms suitable for project application.
Based on these calculations, the number of lamps needed to achieve the desired light level is accurately calculated, as well as the total luminous flux of all light sources in the room, with the possibility of creating several lighting scenarios in the same space.
Importance of lighting control
In the research conducted by the CTA, the agency used a proprietary approach to examine all potential costs of lighting control solutions, determine the range of cost savings opportunities and then calculate the payback periods associated with the adoption of lighting control technology.
Lighting control can reduce the cost of electricity consumption by 35-55%, and calculations are that, with electricity savings alone, the payback on the initial investment for lighting control is an average of 2.7 years (which implies 55% of electricity savings energy) up to 10.7 years (which means 35% electricity savings).
If we consider the longevity of LED lighting, which, depending on the type and purpose of the lamp, can have a lifespan of more than 100,000 working hours, it is clear that this type of lighting can last for over a decade.
The ZenQ company offers lighting fixtures that represent the latest energy-saving technology.
