Daylight Saving Time began this past weekend, a reminder that longer days and warmer weather are ahead.
For many people, the extra evening light brings a noticeable lift in mood and energy. And while that shift feels personal, it also quietly changes how our homes and buildings operate.
Originally adopted as an energy conservation measure, Daylight Saving Time is more than adjusting clocks, it is a natural moment to rethink how we are using energy and what improvements we can make.
At Home
Open curtains or blinds to use natural light.
Update light timers and smart bulbs.
Adjust your thermostat 1–2 degrees
and rememberopen windows before turning on AC when weather allows.
Replace or clean air filters.
Unplug electronics or use smart power strips.
For Buildings
Review lighting schedules and controls.
Align HVAC occupancy schedules with actual use.
Adjust start/stop times for daylight changes.
Check economizer settings.
Schedule HVAC maintenance before peak demand.
Seasonal transitions are a natural time to reflect, and even small adjustments can build meaningful impact.
