This paper presents the project and the economic and environmental evaluation of a ground source heat pump system implemented in a sport centre located in Sora (Italy). The first step of the work has been the estimation and the analysis of the energy consumption of the building, using the energy bills to validate the results. In order to improve the energy system efficiency, three different solution have been proposed and analysed. The first option consists of a geothermal plant and a solar panel plant.

I temi della sostenibilità ambientale sono da anni al centro di varie iniziative soprattutto dell’Unione Europea, che promuove la ricerca di soluzioni atte a preservare le risorse per le generazioni future. La produzione dei rifiuti e lo sfruttamento delle materie prime sono i principali fattori che rendono ancora oggi il settore dell’edilizia poco eco-compatibile.

Solar shading systems play an important role in energy, light and acoustic matters. They works toghether with the envelope as components for energy mediation between inside and outside the building and fulfill the performance that transparent surfaces alone would have difficulty in guaranteeing. Moreover these systems are essential in the qualitative perception of architecture, their appearance and their relationship with the opaque surfaces determin in fact the composition of the façade.

Nowadays energy and energetic fluxes can be considered as main drivers of building regeneration with a relevant influence on the configuration of transformations. In the same way, the long-history towns of Mediterranean area show strict links between urban morphology and climate conditions.

Employees’ wellbeing and comfort perception demonstrated to largely influence their productivity and tolerability of slight thermal discomfort conditions in the working spaces. Their whole comfort perception indeed depends on several parameters related to physical boundary conditions but also to the adaptation capability of occupants themselves and other personal, difficult to measure, variables. According to the available standards and regulations, only physical and measurable environmental parameters must be considered to evaluate occupants’ comfort conditions.
