The performance of ventilation provision in subfloor cavities is relevant to the fields of energy efficiency, condensation risk, and air quality. Thorough…
The functional and technical requirements which have been set for ventilation systems in dwelling houses of the future will result in ventilation systems…
This paper presents some of the early theoretical work conducted within the framework of a research program aimed at analysing the interaction between gas-…
In order to reduce the convective flow which is the principal responsible for the high indoor 222Rn concentrations, several mitigation technics have been…
In an experimental facility, we studied the performance of a task ventilation system designed for use in office buildings. With this system, occupants can…
An investigation has been carried out using computational fluid dynamics methods to study the performance of an air curtain at the door of a heated building…
This paper describes tests of thermal and ventilation performance of two relatively new occupant-controlled localized thermal distribution (also called task…
A new European norm for measuring the heat transfer rate of radiators is under discussion [ CEN TC 130 ]. This testing can be done either in a closed…
The use of computers for data acquisition and analysis in air exchange measurements with tracer gases has become state of the art for the researcher.…
A new facility for the study of ventilation in buildings has been recently developed at the University of Basilicata (Potenza, Italy). This facility…
In the framework of a CEC-DGXVII demonstration project a hygroregulating natural ventilation system is being evaluated in 52 occupied apartments. Therefore…
As part of the IEA Research Program Annex 18 "Demand Controlled Ventilation Systems" various ventilation systems were examined in a test room. During…
This paper describes the activity on Air Infiltration and Ventilation of the research group of "Dipartimento di Energetica" in Politecnico of Turin. The…
With a dynamical model, the thermal behavior of a single office room is simulated. The model includes among other things the behavior of occupants, the heat…
This paper discusses three methods for measuring interzonal air movements in two zone buildings: 1. initial injection of one tracer into a single room, 2.…
The predominant route for air movements between the floors of two-storey dwellings is via the stairwell. Such air movements are of significance in the…
Keynote speech describes the difficulties of designing air conditioning system with human comfort in mind. Lists design fundamentals for satisfactory indoor…
This paper describes the use of tracer-gas techniques to measure airflow in a rectangular duct and a HVAC system. Experimental procedures are discussed for…
Pressure models require a good knowledge of the pressure distribution around the building and a precise description of air paths. The hydrodynamic behavior…
With respect to architecture and building materials, this reorientation process has led to advanced technological developments designed to achieve a…
