Thermal insulation/ Space heating

In order to reduce heat loses you can do the following:

  • Do not cover the heating devices, because their efficiency drops rapidly.
  • Do not ventilate too much.
  • Take advantage of the solar radiation to heat your building. During the sunny days of winter, let the sun inside through the windows in south.
  • Close the shutters and the curtains during the cold nights of winter, in order to maintain the heat in the room.
  • Fill up cracks in doors or windows with insulation material, self-adhesive tapes or silicon.
  • If you have autonomous heating system, do not set the thermostat over 20 oC. For every additional degree, you consume up to 7% more energy. If you feel your space is warm, check the thermostat and be sure that the heating system is off, before you open the windows.
  • Make sure for the correct adjustment and maintenance of burner and clean the boiler every summer by a special technician, who also is issuing a maintenance certificate under legislation with measurements of the installation efficiency, exhaust temperature, carbon dioxide & soot content.

Cooling – Air conditioning

Before you decide to purchase air conditioner, examine any alternative options to feel dew and comfort. Air conditioners consume significant amounts of energy, pollute, heat up the environment and their use is expensive. Air conditioners are not energy savers or cost savers, but some models are less energy consuming than others.

In any case (whether with air conditioner or without) you need to protect your building from the summer sun and the extreme heat. Thus, in order to achieve comfort, the energy you will need to consume will be reduced significantly.

  • Shade all your windows. Choose the appropriate shading system depending on the orientation of the window. In south, prefer horizontal sunshades, constant or movable, in west and east vertical. The external shading is always the best.
  • Plant trees to shade your building, but also create better microclimate when it is possible. You will have natural dew and comfort. Take advantage of vegetation on the roof (improves the thermal insulation, “blocks” the summer sun impacts) and also on the balconies, outdoor spaces, pergola/trellis.
  • Prefer bright colors on external walls, roof and also on awnings.
  • Reduce the internal thermal sources. Install low energy lamps and devices. Do not use high energy consuming devices that also heat up your space (stove, iron etc.) when it is hot. Dissipate heat from your building with natural ventilation. During the warm days, ventilate your building only at night.
  • Adjust your air conditioner using a reliable wall thermometer and don’t seek for temperature less than 26 °C (try even at 28 or 27 °C, probably you would feel comfort).
  • Make sure windows are shut when the air conditioning system is in use, thus no useful energy is lost.

Lighting

  • Let the natural light in from as many sides of your space as possible. By that way you achieve more adequacy and better allocation.
  • Be assured that lights at rooms are not turn on when it is not necessary.
  • Use low energy lamps. One simple filament lamp consumes up to 5 times (energy) than a fluorine lamp which gives the same illumination. Low energy lamps cost more than simple filament lamps, but they have 8 times life cycle and consume 4 times less energy. At the same time we avoid production of 700 kg CO2 emissions and protect the environment.
  • Usually clean the lighting devices and the lamps.
