By Helen Morphew

Today marks UNESCO International Day of Light

International Day of Light is celebrated on 16th May every year. This year’s theme is Light in Our Lives, to let the light guide us the way forward. In line with this year’s theme we’re discussing the importance of lighting within the built environment.

The Importance of lighting in Building Services Engineering

In building services engineering, lighting design stands at the intersection of functionality, energy efficiency, and occupant comfort. Lighting holds an important role in building services, when we talk about lighting, we refer to the simple act of providing visibility by creating a comfortable space. As architects, engineers, and designers strive to craft environments that seamlessly integrate form and function, the significance of thoughtful lighting design cannot be overstated. In this article, we explore some different aspects of lighting in the building service environment.


Building services must not only prioritise aesthetics and functionality, but also embrace sustainability principles. The advent of LED technology has revolutionised the lighting industry, offering a compelling blend of energy efficiency, longevity, and versatility. LED fixtures consume significantly less energy than traditional incandescent or fluorescent bulbs, resulting in lower utility bills and reduced carbon emissions. Moreover, their extended lifespan minimises the need for frequent replacements, further reducing maintenance costs and environmental impact. For example, in commercial settings, such as offices and retail establishments, lighting plays a crucial role in facilitating productivity and enhancing the customer experience. Thoughtfully designed lighting can reduce eyestrain, improve concentration, and even stimulate sales by drawing attention to products or focal points.


On the other hand smart lighting has become more popular over the years, as it uses technology to adjust the brightness and timing of your lights based on things like room occupancy, natural light levels, and what time of day it is. It’s not just convenient; it’s also good for the environment because it helps save energy.


In conclusion, by embracing innovative technologies and sustainable practices, along with a clear understanding of human needs, designers and engineers can harness the transformative power of light to create spaces that inspire, invigorate, and endure.
