Energy and Economic Evaluation of Thermal Comfort. The Case Study of the Hotel Residence L’Orologio

Nowadays, there is a need for reducing building’s energy consumption while preserving a comfortable and healthy indoor environment. After a detailed analysis of the literature in the domain of indoor environmental quality, occupant well-being, health and productivity, the paper explores the relationships between energy retrofit, interventions, indoor comfort and economic benefits and it proposes a real application concerning the case study of a hotel in Turin (Italy). The simulation was carried out through a Cost-Benefit Analysis that allowed to monetize and optimize the economic benefits, in terms of clients’ thermal comfort and employees’ productivity, while preserving the heating energy costs.
