How to save energy in the office?
If an Energy Audit has not been carried out and the possible savings have been analyzed, it can be ensured that there is a margin of electricity savings in any office Green Touch, office or workplace, which could be considerable, depending on the type of office or building where it is. The following tips are separated into two sections: They do not need any investment and they need investment. Both types of advice are valid both for compartmentalized offices, either in large or small premises and for offices located in residential buildings, commercial ground floor or in exclusive office buildings.
Here are some measures that have no additional cost and that can be taken to save electricity in the office:
Raise awareness among office users to save energy. You have to establish a series of internal rules to save and monitor them so that they are complied with, for example, turning off the lights when no one is around, turning off computers at the end of the day, etc.
Establish setpoint temperatures. The optimum level between savings, efficiency and comfort is, according to most experts, 21ºC for winter and 26ºC for summer.
Review the maintenance contracts for the electrical installation (if it exists) and the air conditioning installation (if it exists). Ask other companies for additional estimates and compare.
Other measures that can be evaluated and taken and that require an investment are:
- Improvement of insulation by installing double glazing on the windows. Normally a large amount of energy is lost through windows. Also the frames if they are not well insulated can suppose a significant loss of energy.
- If the windows are oriented towards the South, it is very important to reduce the heat input in summer, but without reducing the light input. This can be achieved by installing any available system, be it blinds, venetians, slats, etc.
- Change of the air conditioning system to a more energy efficient one. You have to seek help from professionals to carry out a detailed study of the most efficient system and request a budget including a study of consumption and justification of savings.
All these factors will cause the energy demand of the building to vary considerably, both in the amount of energy and in the distribution of hours throughout the day. For the thermal conditioning of the building (heating / cooling), considering a conventional building, understood as a building constructed according to the construction customs of each place, the global demands vary depending on all the aforementioned factors.
Indeed, today the achievement of an adequate level of comfort in buildings is usually entrusted mainly to conventional air conditioning systems; to a lesser extent to passive systems and solutions; and hardly any importance is given to the influence of architectural form. Energy efficiency in buildings requires altering the order of these strategies and proposing an inverse scheme, where most of the comfort is achieved thanks to the shape, proportion, materials and orientation chosen; to a lesser extent, but in a decisive way, to passive systems, which take advantage of the surrounding climatic conditions; and, lastly, high-efficiency active systems powered by renewable energy.…
