States that it is possible to integrate HVAC blinds and lighting, which could make possible energy savings, a reduction of peak demand and the improvement of comfort level. Presents some of the results of the INTECOM research project, which aims to define data to be exchanged between different controllers in multi-vendor solutions. The article focuses on the integrated control at zone level. Integrated control strategy performances are analysed by simulation. Prototypes have been produced and assessed on virtual buildings by emulation techniques.

There is a wide choice of new technology to choose from when developing a new line of indoor climate measuring instruments. The paper describes the Dantec company's and the authors' vision for meeting the needs. The focus was primarily on the application. Efficiency has been chosen at the expense of versatility in the user interface. Also describes some indoor climate measuring examples.

Presents a newly developed supervisory control scheme which adapts to the presence of the faults of outdoor air flow control based on online occupancy detection. It also maintains adequate indoor air quality and minimizes any resulting increase in energy consumption. A strategy, which based on three neural networks of the mixing process of an AHU, is employed to diagnose the measurement faults of outdoor and supply flow sensor, and accomplish the fault tolerant control of outdoor air flow when the fault occurs.

Intelligent coordination of the thermodynamical and air ventilation processes can achieve the necessary compromise between comfort demands, necessary air exchange and low heating costs. A new user demand guided field bus based coordination of single room control and air change rate control is developed and tested for a commercial building automation system. A reconstructed block of 65 flats was used in the field test to show that the control strategy ensures the necessary air exchange in an energy-efficient manner.

Evaluates simple methods for the prediction of energy consumption or fault detection as a result of old equipment in a commercial building in Lyon, France. The correlation between electricity consumption and external temperature was analysed.

Individual heating systems have become more and more common in Italy in recent years, as a result of the development of a methane gas network and of general housing renovation. The research proposed some field studies to analyse the indoor climate for improving the heating system and indoor climate. Aims to correct the management of the heating systems to improve housing quality and occupant comfort.

Describes a project which aimed to develop strategies to improve and control the performance of HVAC systems for incorporation into codes and guidelines. One subtask of the project was an investigation of maintenance procedures, including a literature review, the definition of cleanliness for the major components and a 'new maintenance guideline'.

The project aimed to conduct research on the reasons for pollution caused by HVAC systems. It was found that the reasons vary widely depending on the type of construction, use and maintenance of the system. Filter and ducts are major sources of pollutants, with humidifiers and rotating heat exchangers coming a close second. Heating and cooling coils are less of a problem, as is the effect of air flow. Puts forward a new maintenance guideline based on the existing VDI 6022.

Analyses the operation and life cycle costs of industrial buildings using an energy and environmental auditing process. The results will be used in the design of optimized HVAC systems for the future.

Faults and malfunctions in HVAC systems can be difficult to detect with current tools. The survey developed automatic faults detection diagnostic tools for the improvement of buildings facilities supervision.
