I suggest that flexiplace dates are synchronized so that sections of buildings can be maintained at low heating, cooling, and lighting thus saving energy and money and reducing CO2 emissions.
Where I work, EPA-Cincinnati, many employees use flexiplace. This saves travel time, gas, and often is more efficient for certain types of work such as writing reports and manuscripts. However, each employee tends to select any day of the week leaving office and laboratory space irregularly occupied. If we coordinated flexiplace days to the same day of the week, sections of buildings could be maintained at low heating, cooling, and lighting thus saving energy, CO2 emissions, and money. I think this suggestion could be implemented widely, not just at EPA.
