In winter, adjust the thermostat of the radiator or air conditioner to a constant temperature (ideally around 18-20οC). Consumption of 10% more energy is required for each additional degree over the setpoint.

• When using air conditioning in the summer, set the temperature around to 26oC. A low-power ceiling fan can also be used.
Some ceiling fans have a special function for the winter. They remove the hot air that accumulates on the roof of the room and contribute to the proper distribution of heat.
• Make proper use and maintenance of the air conditioner (eg filter cleaning) and the radiator (eg cleaning, burner adjustment, exhaust gas measurement, body ventilation) in order to achieve maximum savings and proper operation.
Heaters should not be covered by curtains, furniture or other objects because their efficiency is reduced.
• Close doors and windows as long as the AC unit or radiator is in operation and ventilate the space with such frequency that there are no high levels of CO2 and relative humidity in the atmosphere.
• To reduce heat loss, insulate the perimeter of the doors and windows and close the protective shutters at night.
• During the winter days with sun take advantage of the heat of the sun’s rays by opening the protective shutters on the south side of the house.
During the summer ventilate space late at night when the temperature is lower.
• Tents can significantly contribute to shading during the summer, thus reducing cooling loads and therefore saving energy from air conditioning (AC) installation.
• Invest in good external thermal insulation of the building shell (walls, terrace, pilotis) as well as in the installation of double window glass frames, achieving savings of up to 50% in heating costs.
