Saving Electricity Behaviour
Using natural light when possible Switch off lights when they're not in use Periodical refrigerator defrosting Turn off equipment not in use Placed refrigerator on distance from heat equipment and sun light Turn off the standby
Saving Electricity Investments
Changing light bulbs to LED Buy efficient equipment that fits you needs Search for the power leaks/thieves Replace old energy consumption equipment (reftigerator, kitchen stove etc)
Saving Heat Behaviour
Wash dishes in a separate container, not under a running tap Switch off the oven a few minutes before cooking time runs out Keep doors and windows closed, ventilate well in 10 min Lower indoor temperature (for very hot flats) Shorter bath
Saving Heat Investment
Install radiator reflectors Draught proofing, Search the heat leaks and stop them Change to well insulating and tight Windows, repair, draught-proof and add extra layer of glass Insulate ceilings Insulate walls Insulation to the ground/cold basement Stop the losses in the heating system (pipe insulation etc.) Regulate the heat Automatic temperature controllers on radiators (thermostats) Air heat recuperation (ventilation with air-air heat exchanger) Aerators for water consumption Water saving shower heads Shorter waiting time for hot water
Use Renewable Energy
Using black water barrels left under the sun for hot water Solar collectors for water heating Solar PV for local use, low volt Solar PV for grid connection Biomass heating (wood boiler, firewood) Biomass heating (wood boiler, wood pellets)
Saving Heat Investments
Solution

Insulation to the ground/cold basement

Saving (Typical Example)
400 kWh/year
Saving Explained

Insulation of the ground/cold basement reduces heat loss through a floor by around 15-20%.

Investment
