Energy Renovation of Buildings Utilizing the U-value Meter, a New Heat Loss Measuring Device
AbstractA new device with the ability to measure heat loss from building facades is proposed. Yet to be commercially developed, the U-value Meter can be used as stand-alone apparatus, or in combination with thermographic-equipment. The U-value meter complements thermographs, which only reproduce surface temperature and not the heat loss distribution. There is need for a device that measures the heat loss in a quantitative manner. Convective as well as radiative heat losses are captured and measured with a five-layer thermal system. Heat losses are measured in the SI-unit W/m 2K. The aim is to achieve more cost-effective building renovation, and provide a means to check the fulfillment of Building Regulation requirements with respect to stated U-values (heat transmission coefficients). In this way it should be possible to greatly reduce energy consumption of buildings.
