Title: Thermal performance prediction of an existing building with framing system using the IRT method
Abstract: Buildings energy efficiency problems are not limited only to the new buildings. In fact, the existing building is often energy-consuming, mainly due to its envelope. A good estimate of the existing building parameters will allow for a better contribution to define the rehabilitation strategies. This work aims to represent the current energy state of an existing building located in the north of Morocco (Mediterranean climate) using in-situ measurements. Firstly, infrared thermography was used to carry out a building thermal diagnosis and determinate the in-situ thermal transmission coefficient. Afterwards, we have proceeded to the energy modelling of this building using TRNSYS software, where each element of the envelope receives a U-value. A comparative study was carried out of three different cases of the building studied using the theoretical and measured U-value for both buildings without concrete frame and with concrete frame. The obtained cooling energy needs of the building diagnosed with the reinforced concrete framework are higher from about 7% to 48% for cooling and from about 2% to 44% for heating energy needs than those of the diagnostic building without the framework and the building reference.
