“…High energy consumption of air conditioning system is due to the fact that maximum ambient temperature is close to 30 • C during the entire year. Other authors [39][40][41] have also determined that it is the air conditioning system the piece of equipment that consumes most energy within a building. It should also be noted that in the 2006 ED, the categories for computers and air conditioning were responsible for 37% and 15% of energy consumption respectively.…”

The purpose of this study has been to conduct an energy diagnosis research of the third level. An energy diagnosis is a tool aimed to seek improvements related to measures of energy efficiency and saving, and environmental conservation as well. These improvements would prove to be relevant for any kind of building. The diagnosis was carried out in 36 university buildings (Renewable Energy Institute—REI) through survey and census; that in order (to identify and) to characterize current patterns of energy consumption and demand, as well as for generating specific strategies towards energy efficiency and saving, for instance the identification of systemic indicators and corrective proposals, and non-financial investment. The results promote the achievement of grand energy efficiency. The task on energy conservation entails the supporting participation of each person who either studies or works in the entity, whereas some other activities require economic stimulus for being implemented. Annual per capita energy consumption in the REI is 40 kWh/person: that is greater than the country’s average consumption rate. The main energy consumption corresponds to Building 3.1 (49% of total energy consumption). This is due to its large concentration of laboratories specialized in renewable energy research and innovation.

“…Energy signature is used as a substitute to regular energy use intensity to assess the energy performance of HVAC and lighting systems with different design operation and operating modes (Zhao and Yu, 2015) alternatively, energy signature models had been used for a long time to evaluate and govern the energy performance of building in various climate conditions.…”

This article presents simulation study on using fuzzy logic based controllers in order to determine building's occupancy level and hence its effect on energy usage. The projected results of energy savings then is used to determine and investigate the proposed fuzzy logic based control system environmental and economic aspects. The proposed system energy performance are measured based on the system occupancy density level, daylight utilization and natural ambient air and humidity. The simulation and modelling engines used in this article are MATLAB and energy plus. Results showed that system will save 14% of total energy demand at 50% of occupancy level compared to total energy demand at full occupancy level (100% occupancy level) and also it is able to save 24% of total energy demand at 25% of occupancy level compared to full occupancy level energy demand (100% occupancy level).

“…Para sistemas de ar condicionado já existentes, a melhoria da eficiência energética pode ser alcançada pela implementação de estratégias de controle avançado e/ou de otimização que permite a redução do consumo de energia, a detecção de erros e a realização de diagnósticos (ZHAO & YU, 2017 O modelo de capacitância global proposto por Pellegrini et al (2018) para a modelagem das zonas foi aprimorado, neste trabalho, como apresentado na Equação (1).…”
