In this paper a detailed scaling analysis of a water tank experiment designed to model a large indoor space is presented, along with experimental results obtained with this model to assess the influence of furniture and people in the pollutant concentration field at breathing height.
Both in domestic and public environments, dampness in buildings is a risk factor for health effects. A European group of scientists has reviewed the literature on that subject including mite exposure over the period 1998-2000. That review has shown that there is a huge need for multidisciplinary reviews in scientific papers including associations between indoor environmental factors and health effects.
The European Community SAVE directive 76/93 makes mandatory for member states to implement an action called Energy Labelling of buildings. The work has been divided in two phases, the first one deals with Officially protected buildings and the second one called CALENER that includes all kinds of buildings.
This Energy Labelling should consist of a description of the energy characteristics and some information about energy efficiency. Its aim is to reduce CO2 emission by means of a parallel reduction in energy consumption.
In hot summer days, in Bucharest the air temperature is over 36°C and the relative humidity exceeds 50 %. That explains the big air-conditioning demand for tertiary buildings. This paper deals with an experimental and a numerical investigation of an air-c
During a field campaign 13 classrooms at 4 different high-schools of the Provincia di Torino and 4 typical medium sized university classrooms of the Politecnico di Torino were monitored during winter and spring season to analyse the environmental quality. Measurements along with subjective surveys concerning indoor air quality, thermal, acoustical, and visual aspects were performed during class time.
The comparison of those results from the subjective and the objective approach is presented.
In this paper, the development of a radiation module coupled with a previous 3D-CFD code is described. This module takes into account the radiative heat transfer between the active surfaces, including those relative to the occupants.
In so far as natural ventilation system is totally dependent on local weather conditions and building facade elements, housing ventilation cannot be permanently guaranteed. This paper offers a computational flow simulation (CFD) which can be used to analyze housing ventilation under different buildings and weather conditions.
The aim of this paper is to give an overview of the work carried out during three years with URBVENT project and to present its main issues: - to provide methodologies and accompanying software tools to assess the potential and feasibility of natural ventilation - to design optimal openings for efficient naturally ventilated buildings.The different partners of this project are: five European University laboratories, two technical centers and one industrial company.
In this paper, different types of local housings have been classified (housing with two facades, housing with two facades in angle or in corner, housing with facade and interior patios, housing with an only facade, embedded housings, in several heights) with the aim of defining the natural ventilation's parameters for them. Then simulations can be made with the selected types along with the validation of results.
