Three experiments aiming at improving the atmosphere in industrial premices are described in this paper. The working conditions of the staff have been improved along with an amelioration of the process and quality of fabrication.The third example proves that a well adapted technical approach allows the improvement of working conditions coupled with an energy control.

The objective of this European Directive, which has to be transposed in national laws in European countries before 4 January 2006, is to promote the improvement of the energy performance of buildings, taking into account outdoor climatic conditions and local conditions, as well as indoor climate requirements and cost-effectiveness.
The directive lays down esuirements as regard :
a - the general framework for a methodology of calculation of the integrated energy performance of buildings (including aspects such as ventilation and indoor climatic conditions);

This study compares indoor climate, cooling efficiency and energy consumption of an underfloor air distribution system and a ceiling-based system in a test chamber. Floor-based system appears to provide better thermal conditions with lower electricity consumption.

In contemporary architectural design, the indoor climate receives little attention. Most architects are not familiar with the typical problems and solutions involved in climate design. However, it is this relation that provides much control over the initial climate conditions and can prevent costly artificial solutions. As a result, many design decisions are made without insight into the consequences on the indoor climate.

This paper presents 3 full-scale test rooms in a series of 14 built in Italy, with different types of façades. The measurements of energy consumption and indoor environment allow a direct comparison between different solutions exposed to identiacal climat

The study was to evaluate energy use of ventilation system with supply in corridors and exhaust in wet rooms. The field test protocol was to measure energy use one day with corridor supply ventilation on, one day off, for a range of different outdoor temperatures in winter. When corridor supply is on, the internal pressure changes (although always negative) and infiltrations are modified.

Describes what could be the requirements of a European standard (not yet numbered) prepared by Technical Committee 156 (Working Group 7) of CEN (European Standardization Committee) about the calculation of energy requirements for buildings with room conditioning systems.

The article presents the scope and content of ISO 13790 standard which is intended to calculate the energy use for space heating of buildings. Information is given about the accuracy of the standard calculation method.

The indoor environment is by far the most important environment from a health perspective. Allergies, airways infections, lung cancer etc. are associated with indoor air quality (IAQ) in developed countries and they are related to the use of energy for buildings. The main problems related to buildings, energy conservation and health in the developed world concern 'dampness' and inadequate ventilation. It is well established that if there is no 'building dampness' and if the ventilation is adequate then the risk of IAQ-related diseases is low.

During the last two decades the significance of indoor environmental quality in buildings has been appreciated, not only in relation to thermal comfort, but also to indoor air quality. Ventilation is an important tool for securing both a good indoor climate and air quality. However, in buildings without mechanical ventilation and air conditioning systems (which comprise the majority in most European countries) natural ventilation presents the only means to satisfy indoor air quality needs.
