Abstract: The purpose of this numerical study is to evaluate the thermal comfort and indoor air quality provided by a surface confluent jets ventilation system applied on a virtual occupied chamber. This numerical study is carried out using a coupling of an integral numerical model, that simulates human thermal response systems, and differential numerical model, that simulates the computer fluid dynamics. The Draught Risk around the occupants, thermal comfort, indoor air quality and Air Distribution Index (ADI) are evaluated. The study was performed for winter and summer typical conditions. The results show that the surface confluent jet system presents, in general, an acceptable thermal comfort level and an acceptable indoor air quality, with carbon dioxide concentration values below the limit of 1800 mg/m3. The ADI value is better in winter than in summer conditions

Abstract: In this numerical simulation the Building Dynamic Software is used in an application of underground thermal energy storage in a university building with complex topology. The numerical simulation is made in summer conditions with mediterranean environment. In this numerical simulation, the passive and active solar strategies are considered. Building Dynamic Software calculates the air temperature of the spaces, the surface temperature of opaque bodies, transparent bodies and internal bodies, the mass of contaminants and water inside the spaces and in the surfaces, the thermal comfort and air quality and the energy transport and consumption. The university building is divided into 319 spaces, distributed by four floors, and is composed by 329 transparent surfaces (windows) and 3585 opaque surfaces (internal and external walls, doors, and others). Below the ground floor is considered, numerically, an underground floor, with the same area of the building and with a typical floor height, u
