| Sumario: | The following document presents a Master’s Thesis that pretends to carry out an Energy Audit of the Bellvitge UB Health Science Campus using the software Design Builder. The aim of the thesis is to identify the main weaknesses of the building under study, in order to develop a proposal for improvements to reduce the associated energy consumption. In first place, there is a preface, where the main reasons to develop this project are explained. In second place, the objectives of the thesis and its scope are defined. Afterwards, an introduction to the studied building from the constructive point of view is made. Once this explanation has been completed, the process by which the architectural modelling of the Campus has been carried out can be found. Below it is described the current technical building system. This study has allowed understanding its mode of operation in order to have the widest information for its modelling through Design Builder. From this point on, the HVAC model is presented. In this description, one can find the justification of the introduced simplifications, which have been made in order to solve the limitations caused by the used software. Once justified, the obtained results from the annual hourly simulations are shown. These results have been compared with the real consumption values of the Campus in order to evaluate the calibration process and thus assess its validity. Based on its analysis, the main problem of the building has been identified, its high interior lighting consumption. Two measures for improvement are proposed below to reverse the current situation. The first of them consists on replacing the current lighting with a LED system, and secondly (chained to the obtained scenario after applying the first proposal) the implementation of photovoltaic panels in the outdoor area located on the fifth floor of the Campus. The application of these measures would reduce the overall consumption of the building by 31%, thus increasing its energy efficiency. |
