Abstract: The insulation performance of building envelopes is one of the areas with a significant impact on the building energy intensity. In Poland, 71 % of the energy demand of the entire building is used for heating households. Therefore, solutions are sought that will ensure the required thermal comfort and reduce the energy demand. The paper presents the testing of the temper- ature distribution inside an envelope made of structural insulated panels (SIPs) using state- -of-the art FBG sensors. Compared to classic temperature measuring devices, FBG sensors are characterized by high measuring resolution and reliability, reducing the testing invasiveness to the minimum. A composite structural insulated panel (SIP) and a traditional two-layer wall were tested. SIPs are modern building materials that are both a structural and an insulating element of building envelopes. The three-layer structure consists of a light core (EPS) skinned on both sides with magnesite boards which provide the panel with high strength, rigidity, fire resistance and resistance to biological corrosion. The knowledge of the actual temperature distribution inside the envelope can significantly improve the control of heating systems in buildings and reduce energy consumption.
