How to Make the Most of Your Daylight Hours

Wednesday, March 10, 2021 By Niki Schillero

Ready or not, we’re springing forward!

Daylight Saving Time starts at 2:00AM on Sunday, March 14, 2021. As we move the clocks up an hour, it's important to know some key tips to take advantage of your facility's lighting hours.

There are many approaches that can be taken in order to maximize daylight savings. The two most common methods when paired with lighting controls help reduce your operational costs and increases your energy efficiency: 

  • Daylight Harvesting
    Daylight harvesting is an approach that can be used to collect and utilize natural daylight within a space by automatically adjusting light levels - as the amount of daylight increases the light levels will automatically decrease to maintain a well-lit space and also save energy.

    Daylight harvesting controls use a photosensor to detect natural light, which then send a signal to partially or completely reduce the light output.These photosensors can operate with natural or artificial light. Open-loop sensors placed near exterior points detect available natural light. However, buildings can also use closed-loop systems that have sensors within, detecting both natural and artificial light. Sensor inputs are then evaluated, and the switching or dimming system will then adjust the light level as needed.

  • Time Scheduling
    Time scheduling allows time clocks to determine whether lights are on, off, or dimmed. Schedules can be predetermined and preprogrammed to create appropriate light levels for when an area will be occupied or not. This is not a complex control, but it is highly effective for cost savings, energy reduction and providing certain level of convenience. As one of the most widely used forms of controls we see, and it applies to many applications such as parking lot lights, operating hours vs after hours schedules, retail lighting, etc.

    By implementing these simple solutions, you can reduce the amount of time your lights are on, while still retaining appropriate light levels. If you are currently operating timers and/or EMS systems, remember to adjust them to accommodate for Daylight Saving Time starting at 2:00 AM on Sunday, March 14, 2021.


If you and your organization are looking for technical assistance and support to optimize your short-term and long-term savings, Lightserve and Illumetek, a Division of Lightserve have multiple Certified Lighting Controls Professionals (CLCP) on staff. We can provide helpful insight on the implementation of this technology within your facility or multi-site portfolio. Feel free to email us at sales@light-serve.com or at hello@illumetek.com.
