Guidance to avoid health risk caused by energy saving measures in homes
From - 31 March, 11:32

Due to extreme increases in energy prices in European countries (as well as other non-European countries), building users may be tempted to take energy saving measures because they can no longer pay their energy bills. This in turn may have adverse effects on the indoor air quality - especially in older and badly insulated homes. This article gives some elementary advice on what people should and shouldn’t do in cold and temperate climates where indoor heating is normally needed in winter.The point is that energy savings can be achieved, and adverse consequences avoide...
