12 simple tips for rational use of natural resources, water and energy in your country house or city apartment - extended in Sept 2019

  • Surrounding vegetation: on a trellis or mesh next to your windows/openings facing East or West, grow deciduous vines – which shade in summer and allow sunlight passage in winter. Those who cling to walls may become a "summer second skin" of the built environment.
  • Summer 1: allow breezes entry for cross-ventilation, with outlet openings on the opposite side of each space entry. Note: The air flow rate is increased if the output area is greater than that of ​​the input (Venturi effect, as in a chimney).
  • Summer 2: If your house has an attic, allow openings for extracting the warmer air by natural convection. If it has a basement, allow passage of its cooled air to the living space.
  • Winter 1: isolate upper and lower areas from the main living space.
  • Winter 2: If necessary, employ an oven or fireplace - with higher yield than those that are decorative only, with double combustion, higher efficiency and lower production of polluting emissions.
  • To minimize the energy consumption of commercial air conditioners, when outside temperatures are higher or lower than those of the thermal comfort zone, use shadowing (external, if possible) and double-glazed windows
  • Reduce electricity consumption in water heating, using thermo-solar collectors or gas (natural, if possible) in a passage heating system.
  • Organic waste: In addition to selective waste separation that allows recycling of inorganic material, do aerobic composting with your kitchen waste in well-ventilated containers. Fermentation, which heats up without producing an undesirable smell, results in fertilizer for your plants (earthworms can be introduced for pre-humus production at a later stage).
  • Rainwater harvesting: If your building has separate water systems, one for toilet discharges and another for other consumption outputs, integrate the toilet system to the rain capture through gutters on the roof.
  • Rainwater can also be stored and used directly in gardens or flower beds.
  • Water treatment: the "gray water" output (showers, sinks, etc) can go through an anaerobic bacterial treatment tank for all non-drinking needs. The "black water" from toilets requires more bacterial treatment stages and can be used for ferti-irrigation of gardens or flower beds.
  • Better than to replace incandescent bulbs with fluorescent lamps is to replace those with higher efficiency LED arrays. So you will decrease your electric consumption, own a long-term savings and contribute to the environment (by avoiding pollution with mercury).
