Saving energy > Houses

More than half of your domestic energy consumption is used for heating your home. Proper insulation of walls and roofs and the use of insulating glass has a huge effect on your energy consumption.
Lower your thermostat by 4 to 5 degrees Celsius during the night and when no one is at home.
On a windy day feel for leaks. Also look for spider webs - if there is a web there is a draft.
Keep heating radiators clear of furniture, curtains and rugs.
Plug gaps around pipes, ducts and fans that go through walls, ceilings and floors from heated to unheated spaces.
If you have a fireplace, close the damper to prevent warm air from escaping through the chimney, and make sure the damper fits tightly.
Switch-off your home appliances, instead of leaving them in stand-by mode.
Stand-by mode account for some 10 percent of your home energy consumption.
