Building Energy Demand Forecast Methodology (EDCE)
For the optimal sizing and determination of the HVAC system in a building, the precise calculation of the energy demand is an essential task, especially in cases of geothermal installations, due to the fact that the effort and the costs of any afterwards modification are high. Thus, the initial calculation and dimensioning of the installation are crucial to guarantee that the expected system’s performance is achieved.
Nowadays, the dimensioning of a building’s installation can be made in 3 different ways: i) The use of empirical methods based on energy demand estimations, ii) use of real operation energy consumption profiles (acquired by the building’s SCADA system), or iii) use of detailed building energy simulations to accurately characterize the energy requirement of the building.
