Five Years of Laboratory and In Situ Test Experiences to Verify Therms Comfort Conditions in an Innovative Hybrid Ventilated Building

AbstractClimatisation and natural ventilation concepts are today, in most countries, considered to be an essential aspect of the building project. In fact they are utilised to guarantee summer thermal comfort and indoor air quality control. Also there are many other advantages including low energy use, reduction of noise levels and easy plant maintenance. In recent years the use of hybrid ventilation systems in office buildings has been developed. The achievement of thermal comfort conditions in buildings is an important aim in order to satisfy occupants. To achieve a high level of life quality a study of climatic parameters of the ambient air is needed. International Standard ISO 7726 and ASHRAE Standard 55-81 define the values of parameters affecting thermal comfort in offices. The aim of the present work is to evaluate the fluid dynamic phenomena connected to the running of the air conditioning and natural ventilation systems in an innovative office building, constructed in central Italy, aimed at achi...
