In this paper, the results of the elaboration of the experimental data from 1-year longmonitoring of the performances of an innovative HVAC system installed in a multi-roomscinema of the Warner Bros Village near Venice is presented. This system is based on a rooftopexpressly designed for cinemas applications.The behaviour is analysed to verify the machine design choices in terms of reliability,energy efficiency and comfort level achieved. The study confirms the validity of the designwhich characterizes this HVAC system.

The aim of the study was to develop solutions to the problems and deficiencies encountered inventilation systems of day care centres, and which were manifested as poor IAQ or excessiveenergy consumption in the buildings at the maintenance stage of their ventilation systems.During the afternoon rest hour the IAQ was monitored and other measurements of ventilationcapacity were made. The directors and maintenance personnel of the day care centres wereinterviewed and a questionnaire was presented to the staff.

An investigation method based on the HACCP system was applied to eleven representativeoffice buildings with HVAC system located in different latitudes in Italy, to evaluate themicrobiological quality of the air supplied. Bacterial and fungal levels near supply airdiffusers pointed out medium-low contamination and analysis of data showed a highermicrobial load in the buildings located in the South of Italy with respect to those in the North.IAQ of five buildings was examined in more detail. Air samples demonstrated an overallgood microbial removal efficiency of the examined HVAC system.

The ventilation system of a hospital operating theatre is designed to provide a comfortable andhealthy environment for the patient and the surgical team. A healthy environment can beachieved by minimizing the risk of contamination through an appropriate filtration and airdistribution scheme. The design and construction of operating theatres in Hong Kong,including the upgrading of the older ones, are based on the UK Health Building Notes andHealth Technical Memoranda.

Since the initiative by the government in 1999, indoor air quality (IAQ) has received attentionfrom the community at large in Hong Kong and the education sector has also been activelymonitoring IAQ in line with the proposed objectives. This paper reports the finding of an IAQstudy conducted in 2002 at two vocational education institutes. It begins with a brief review ofIAQ development in the education sector. An outline of the site inspection, the IAQ objectivesand the equipment used in the study then follows.

The paper presents the first and the second phases of a work in progress aimed to prepare aguide for the IAQ evaluation of the real estate of the Politecnico di Milano University, intended for the technicians of the university building department.The overall work is structured in four phases: (1) census and classification of theconstruction and technical features of the buildings; (2) preparation of a check-list for thedetection of hazards based on homogeneous category of building; (3) monitoring ofrepresentative building of the Politecnico real estate; (4) proposal of techniques and materi

The main objective of this study was to investigate the Indoor Air Quality (IAQ) in officebuildings and to understand better how HVAC (Heating, Ventilation and Air-conditioning)systems work and what their effects are on IAQ over a sustained period. Two Frenchcommercial buildings were chosen, located in urban areas of Lyon and Paris, and for one daya month, over the course of 1 year, a number of IAQ related variables were recorded bothinside, including the HVAC system, and outside the buildings.

In Germany, the radon concentration of 200 Bq/m3 in accordance with the European recommendation (Kommission der Europäischen Gemeinschaften, 1990) is valid as design level for new buildings. Radon from building material can make a significant contribution

The adverse health effects and costs of IAQ problems could be reduced significantly with proper use and maintenance of buildings and early detection and remediation of problems.Dissemination of information is the key to these savings. Therefore, the Finnish ministries responsible for IAQ decided to launch an education and information campaign IndoorClimate 2002. The activities were coordinated by the Finnish Society of Indoor Air Qualityand Climate (FiSIAQ).

IAQ investigators have a responsibility to give correct advice to the client. In cases with mould growth, the question of people’s health is often involved. Economical aspects can also be considerable due to the high costs of necessary actions during and
