LED lighting has two principle benefits for office environments even though the cost of the light bulbs is higher than a traditional halogen bulb. The first is that they require less power and normally by a factor of 10 to achieve the same or higher lighting (measured in Lumens). So a traditional 60W bulb can be replaced by a 6W bulb. The second factor is that being more energy efficient, LED lights give off less heat and so do not add to cooling costs. This can be a downside in warehouse environments with high roof spaces.

It is always difficult to achieve an ambient environment in an office that suits everybody using it. The larger the office the worse the issues can become. A zoned heating approach can help using thermostatic controls on radiators and smart thermostats driven by phone or desktop Apps for air conditioners. This should allow individual areas to be heated or cooled to suit the individual occupants. The most energy efficient approach is to have a set constant temperature for the complete office.

Smaller UPS systems below 10kVA in size are typically used within office environments to protect IT network servers and their local area networks. On-line UPS around 5-10kVA typically achieve an energy efficiency of around 95% or greater in on-line mode and up to 98% or more if they have an Eco line interactive mode. Smaller UPS tend (below 5kVA) tend to be less energy efficient and may be on-line, line interactive or even standby models. The size of the UPS and its rating will have little impact on overall energy efficiency in a medium to large office environment. Even in a small office, the losses from the UPS will be negligible.
