A temperature setting of 68°F during the winter months is often recommended to maximize energy savings in the workplace. This setting can reduce heating costs dramatically compared to a more traditional setting of 74°F. Studies have shown a relationship between worker productivity and building temperature, however, so you may want to consider this before making any thermostat adjustments.
A study by the U.S. Department of Energy's Lawrence Berkeley National Laboratory (LBNL) found that worker performance increases with temperatures up to 72°F, and decreases with temperatures above 73°F. The highest productivity was at a temperature of around 72°F.
A setting of 72°F appears to be the sweet spot for optimizing productivity, even though it may be less energy efficient than 68°F in the winter. Remember, however, lower productivity can cost you as well.
Additional ways to optimize comfort and productivity:
- Hire a qualified professional to inspect and clean your heating system.
- Change air filters regularly according to manufacturer guidelines.
- Make sure registers are unblocked by furniture or equipment to ensure proper airflow.
- Check for gaps in windows and exterior doors and seal them with caulk or weatherstripping.
Consider installing a smart thermostat. Smart thermostats automatically adjust temperatures based on your operating schedule while providing you with remote control. Some models can incorporate data from sensors and use weather information for smarter control.
