Optimization of the consumption and daylight illuminance of an hospital building; the Morelli Hospital case study

The thesis has the goal to analyse the design trend of new buildings, with big windows opening and good insulation envelope, these solutions are not only a trend but are necessary to respect the new norms. The analysis starts with the implementation of the model in DesignBuilder of the new Morelli Hospital in Reggio Calabria designed by Steam Srl. The simulation model is constructed in DesignBuilder, incorporating all the building’s structure, the envelope and a simplified HVAC system. From this simulation, lots of data can be extracted regarding the building's energy consumption and indoor illuminance levels. This thesis specifically focuses on maintaining optimal visual comfort by ensuring adequate daylight illuminance throughout the day, in compliance with CAM 2.4.7 standards for public buildings, without increasing the building's cooling energy demand. Several simulations of indoor daylight illuminance are performed, considering different configurations of windows and external shading devices. When the CAM requirements are met, the peak power, cooling, and heating energy needs of the building are calculated. The study identifies the optimal solution to minimize energy consumption, particularly during the summer. The work of this thesis is the base to create a standard to informing who design the building structure what are the best solution to increase energy efficiency of the building and respect the norms.
