A home office added monitors, desktop computers, chargers, printers, networking gear, task lights, or always-on devices.
Most office devices are not huge by themselves, but multiple devices running all day can become part of the home baseline, especially with desktop computers or large monitors.
Check first
List desktops, laptops, monitors, printers, speakers, routers, chargers, and lights.
Estimate hours on, sleep hours, and always-on devices.
Compare office equipment cost with HVAC and lighting changes.
Check whether time-of-use rates make work hours more expensive.
Practical savings moves
Use sleep settings and turn off equipment that does not need to stay on.
Unplug rarely used chargers and accessories where practical.
Use measured wattage for desktops and monitors when possible.
Compare device savings with bigger HVAC or water-heating opportunities.
Avoid these mistakes
Do not overestimate a laptop using charger wattage as constant draw.
Do not ignore always-on networking equipment.
Do not chase tiny standby savings while missing daytime HVAC changes.
