Building Energy Certification System: Application to a Building in Lisbon and Paths to a Future Enhanced Scheme

ABSTRACT Energy efficiency in buildings is of particular importance in the pursuit of international objectives in the area of climate and energy, as it is a sector that represents approximately 40% of total primary energy demand, with strong growth prospects for absolute consumption [1]. In Portugal, the implementation of the energy certification system (SCE) and improvement of indoor air quality is an important step in the promotion of energy efficiency and the achievement of national targets regarding the emission of greenhouse gases [2][3][4]. This article presents the application of the SCE system to a large office building, the Lisbon City Hall. In the context of the energy audit that was performed, different energy optimization scenarios were defined and analyzed in a cost-benefit perspective. Emphasis is placed on the calibration of the building thermal simulation model (EnergyPlus) and its results [5]. Based on this application of an energy certification code, an examination of the principles that...
