Society is under constant development and it directly entails greater comfort demands for daily activities; these demands are reflected in a continuous increase of energy consumption that is used to satisfy them. According to EU policies to reduce emissions of greenhouse effect gases and considering that the building sector in Spain consumes almost 20% of total primary energy, new solutions are required to be applied in the existing buildings, given that using passive architectural systems can reduce up to 75% of energy building demands. In this context, this project focuses in the study and quantification of the energy performance of the building systems and construction elements. Two methods lead to this quantification: energy dynamic simulation with PC software and energy monitoring in eeLAB laboratory. Comparing real data with simulation data will help to know both possible deviations of in situ test – due, for example, to small deviations in measuring instrumentation, as the limits or fluctuations in the software simulation results. To obtain real data, a proper enclosure was developed for data gathering (eeLAB) as a test equipment based on an open wireless protocol, which allows it to be easily implemented. The analysis of data obtained from the two methods will allow us to parameterize energetically the building systems most commonly used in construction. This quantification will provide the different agents of building process with objective criteria for selecting building products and building systems more energetically efficient and appropriate for each location and orientation of the building. Keywords: energy efficiency, building envelope, energy monitoring, simulation.
