Lighting is one of the most important elements to consider when designing any space, and this important tool is continually evolving. Meeting the requirements of the state, county and national regulations, as well as the electrical engineer’s energy model, necessitates the evaluation of our client’s needs on a grand scale. This evaluation must balance many factors including budget, aesthetics and energy efficiency.
Though the first cost is still considerably more than conventional fluorescent and incandescent luminaires, LED lighting is the way to achieve both the low wattage requirements and the appealing effect. With this in mind, a realistic approach to the lighting budget is important. Considering that the savings over time will well outweigh the initial cost, LED lighting is an investment that pays off.
Not only will the cost of electricity be substantially lower, the greatly reduced labor (to re-lamp) and bulb replacement expense quickly help to recoup the initial cash outlay. Additionally, when renovating a building, consider the many retrofits LED lamps on the market. There could be no need to replace light fixtures and Pepco rebates may well be applicable. Whether using retrofit lamps for a renovation or new construction, choosing the right color temperature and rendition is critical to setting the mood and obtaining the desired ambiance. For calm, relaxing spaces, consider using soft, warm lights with orange and yellow hues (2700K or warmer). For a room that is intended to be livelier, like a fitness center, a slightly cooler temperature (3000 or 3100K) is ideal. The color rendition of 80 or higher is recommended for the best color interpretation.
To create the mood, many different types of lighting fixtures are required. Downlights provide general lighting and pooling of light on the floor, accent lighting is used for special features and art, while sconces and chandeliers are used for additional layering of light as well as decorative elements. The good news is that there are LED lamps for most fixture types today so you can easily achieve the look desired and contribute to the green initiative. If you’re working with an interior design firm, make sure everyone has a clear understanding of the mood you wish to create, the budget and required energy efficiency. Your interior designer will know the best way to utilize the natural light coming into the room, and how to properly support that light with general, task, accent, or a combination of all three types of lighting.
