Warm Sweater day is an awareness campaign that was started by the Dutch Climate Bond. Many organizations, companies, universities and schools of The Netherlands take part in the national Warme Truiendag . On that day in the corridors and in the rooms of the buildings, the heaters are set a few degrees lower. Are you energy conscious? Then join and set your radiator a few degrees lower! For each one-degree change, your family can save up to 5 percent on your home’s heating and cooling costs! I always have one problem: freezing hands, but this year I am ready for the winter and lets introduce the warm sweater day everyday.
