Appliances that heat water or food can have quite an important contribution to overall consumption. In many cases, they are much more convenient to use and more efficient and than, for instance, simple teapots used on an electric cooking machine.

Purpose built devices can be optimized and this is certainly the case. However, just like any device, it stands to reason that they have to be determined as essential to be used in a certain manner.

In the case of an office, it all boils down to convenience and a pleasant working climate. If few employees use such devices on a constant basis, there is no major concern about consumption, although more efficient devices would help in limiting consumption.

Space heating and cooling may require considerable amounts of electricity. It may be helpful to establish specific temperature ranges at which appliances are turned on an off to maintain comfort. This will have a very large impact, particularly in summer. Permanent monitoring of temperature and humidity is essential to asess how to maintain it in an acceptable range.

Water heating that depends on tap water also evolves thought a year. Since tap water is cooler in winter, boilers are requiring more electricity to heat the water to the same temperature than during summer. Also, in summer, hotter water may be less desirable to work with, so a lower temperature can be sufficient.

All these situations have to be carefully studied. It is not as effective to just use the "eco" function for certain devices, since it will just provide a lower service, in this case water temperature and electricity consumption, that may not be satisfactory for most purposes.

Ensuring a properly lit indoor or outdoor used to require significant energy consumption. This may still be the case for very old installations but retrofits or modern systems are rarely high consumers.

A higher surface area that has to be light and more intense light leads to higher electricity demand and energy consumption. Of course, the more lamps installed and used in a place, as commonly is, the higher the total monthly consumption.

Lighting systems tend to not require high investments for modernization purposes but some specialized systems may still command a high price, so it is advisable to understand the current situation.
