La désinfection des réseaux aérauliques Disinfection of air-handling ducts

A kind of protocol for the desinfection of air-handling ducts is presented in this paper with its different steps : relationship with the customer, available techniques, prerequisites for the desinfection, choice of the products and the desinfection itself.
The limits of the system are presented too along with possibilities to develop.

Levels and predictors of endotoxin in mattress dust samples from East and West German homes

In so far as prevalence of asthma and allergies is different from East to West Germany, a suggestion that it was associated with lifestyle factors was made. The endotoxin levels in dust collected from more than 4000 infants and mothers mattresses were compared. But none of the predictors analyzed and even a combination of predictors can be used as a surrogate for high or low mattress dust endotoxin levels in epidemiological studies.

Pollutant dispersion in a large indoor space : Part 2 : Computational fluid dynamics predictions and comparison with a scale model experiment for isothermal flow

This paper reports on an investigation of the adequacy of CFD for the predicting isothermal pollutant transport in a large indoor space with simple geometry, no furniture and no occupants. Agreement between predictions and experimental measurements was good.

Pollutant dispersion in a large indoor space : Part 1 - Scaled experiments using a water-filled model with occupants and furniture

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.

Dampness in buildings as a risk factor for health effects, EUROEXPO : a multidisciplinary review of the literature (1998 - 2000) on dampness and mite exposure in buildings and health effects

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.

Building energy labelling in Spain (Calener), technical basis

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.

Thermal comfort and environmental quality in high-school and universtiy classrooms - Objective and subjective surveys

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.

Estudio tipologico de los locales residenciales segun su sistema de ventilacion natural Study of local housings with their system of natural ventilation

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.

Improved building energy consumption with the help of modern ICT

Climate change is a long term battle that involves the whole international community. The need for better energy efficiency is obvious. The energy efficiency of the existing building stock must be improved. Thanks to Information and Communication Technologies (ICT) a lot of possibilities for the development of new type applications and services are present. Internet will be the main platform for the development.

Case studies of energy information systems and related technology: operational practices, costs and benefits.

In this paper EIS (Energy Information System) is first defined, then 4 case studies are presented, one in detail because it is an example of high-end EIS and the other cases are summarized briefly. For all the cases operational practices, costs and benefits are presented.
