ABSTRACT
This paper reports on the energy consumption study of a typical Valencian house with the aim of achieving a maximum reduction in HVAC energy demand. With this purpose, an extensive simulation project was done by using TRNsys 17 software. Previously, all necessary data were collected and studied. Then, an energy simulation of the original house was performed, hence obtaining experimental evidence to verify the predictive capability of the developed energy model. Subsequently, the energy optimization strategy was proposed and the measures to improve the energy demand were implemented on the model, in order to reach a zero HVAC demand. Finally, the following conclusions were obtained: energy model adjustment is fundamental for reproducing the specific thermal behavior of the studied building and for the optimization of the energy demand and secondly, enhancing the building envelope is the most effective proposal for achieving the reduction in the HVAC requirements for the building.
