In any structure, lighting is among the most important factors that architects consider. Light does not only affect the building’s aesthetics, it also determines the amount of energy that the building’s occupants would need. To ensure efficient energy usage, an increasing number of architects in the Philippines employ lighting methods that drastically cuts back on energy consumption.
The paragraphs below discuss some options available for energy-efficient lighting.
Maximizing Usage of Natural Light
Natural light or daylight is an unlimited resource that architects could fully maximize for lighting interiors. Most architects prefer using light colors for the interiors to increase the reflectivity of light that comes in through the structure’s skylights and windows to brighten the rooms. Another method to maximize usage of natural light is the usage of internal shading devices for the structure’s windows.
Usage Low-Cutoff Lighting Fixtures
Interior and exterior lighting are obviously two different aspects that architects consider. While exteriors also require good lighting, architects are careful to avoid overly illuminating outdoor areas. To this extent, architects prefer the usage of low-cutoff lighting fixtures that would direct light downward instead of outward and upward.
Usage of Light Emitting Diodes (LED) Light
LED lights are gaining more and more popularity among architects in the Philippines. This increasing popularity of LED lights in the Philippines is due to their efficiency in generating light in comparison to the ordinary incandescent bulbs most Filipinos use in their homes.
To understand the advantages of LED light, we first need to consider its benefits in comparison to incandescent lighting. Incandescent light bulbs make use of filaments to generate light. Over time, however, the filament burns out and fails to give off any light. On the other hand, LED lights do not make use of filaments. When LED lights fail, they do not just abruptly burn out but rather, just dim over time. Whereas 90% of the total energy that incandescent light bulbs consume becomes heat only, all of the energy that LED lights consume converts to light energy. LED lights are, therefore, more efficient in energy consumption than incandescent light bulbs.
We can also appreciate the benefits of LED lighting when we consider its structure. Unlike incandescent lighting, which requires usage of filaments and bulbs, LED lights consist of solid material that does not contain any breakable material. Apart from its durability, LED lights are capable of generating 135 lumens per watt and have a lifespan that can go as high as 50,000 hours. LED lighting also ensures excellent color rendering as the light it generates does not wash out, unlike other man-made light sources. Its consistency in color rendering and short startup time are why engineers make use of LED lighting in applications that require frequent on-off cycling.
LED lights also promote efficiency in the amount of light it gives off, as users can direct the light wherever they want it. Users of LED lights can also control the degree of brightness as well as the color of the light that they generate. Most importantly, LED lights do not contain any mercury or toxic substance, making them safe and environmentally friendly.
