A building's overall energy performance is related to the variation of its energy balance and the extent to which additional heating or cooling energy is needed to maintain comfort. The characteristics of a building impact the energy performance in ways that vary over time. For this reason, there is a need for development of techniques that estimate buildings’ performance and reduce their overall energy consumption.This diploma thesis deals with the formulation of a strength methodology for quick development and analysis of the interaction between building loads. In this way, exorbitant amounts of financial costs that may arise from extensive energy analysis, which frequently become unaffordable, can be eliminated. The proposed methodology allows to understand building’s energy performance as a variation of its energy balance needed to maintain comfort.For its development, the case study used is the Olympic size swimming pool in Chania (located in university campus), maintaining its dimensions, as mentioned in the AutoCAD architectural drawings. The building envelope was designed using the Google SketchUp program and the Openstudio plug-in software, after taking some necessary admissions of its unknown operating parameters. Furthermore, the simulation parameters for the conduction of the thermal analysis were implanted using the EnergyPlus software, while special care was given to the exact definition of the Variable Air Volume System (VAV) used for the air conditioning of the internal spaces. After the analytical evaluation of the energy performance and the behavior of the natatorium in the requirements, proposals for energy upgrading were presented, aiming both at saving energy and operating costs and also in reducing the emission of pollutants in the atmosphere. In specific, proposals referred to the installation of an Efficient Natural Ventilation System, the use of Low-Emissivity Glasses and the construction of South Oriented Shadings. After being simulated through the same software, the results showed energy savings per 1.39%, 2.15% and 1.44%, while the operating costs’ savings were 1070.87 €, 1655,59 € and 1159,400 €, in correspondence to the order that the proposals were previously mentioned. In conclusion, the time period during which, amortization of the initial capital spent for every proposal will be achieved, was calculated and resulted in 9, 17 and 7 years.
