Indoor air quality of an energy-efficient, healthy house with mechanically induced fresh air

Issues associated with indoor air quality (IAQ) and its impact on occupant health have prompted research into the design and construction of healthy houses. Most of the houses constructed have been upscale housing. An affordable, energy-efficient, healthy house was built at Tuskegee

Some schools at risk for poor IAQ

In this paper, the author presents what could be done to improve the poor indoor air quality in some schools :- A demand for accountability from school systems about maintenance procedures such as roof-leak repair, classroom ventilation and air-conditioning, presence and care of carpeting etc.- A promotion of a responsible and adequate funding for the maintenance of public facilities- The most important activity is a good, basic, responsive and adequately funded building maintenance.

Standards indoor air quality involve a new design for ventilation housing system

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.

Interior air quality, energy and productivity

Fresh air has a very important role in indoor air quality.This study aims at quantifying the costs and the gains of an increase of the ventilation rate, in an office building. Results show that a big increase of the ventilation rate leads to an increase of the installation costs, but to no change of the energy costs. The additional costs may be paid back quickly due to the productivity improvement.

Indoor air pollution in urban buildings. A real threat for most of the world population

In developed countries, the concentrations of indoor pollutants are very similar to those outdoors. 3 basic strategies are proposed to reduce occupant exposure to indoor contaminants : 1. Building air tightening and pressure management2. Ventilation and air filtration3. Contaminant removalIn poor countries, the use of advanced ventilation and filtration techniques is not feasible at all, natural ventilation may be one of the more effective solutions

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.

Standard 62.2 approved-ASHRAE publishing residential IAQ standard

Standard 62.2. is the first and only recognized Indoor Air Quality standard for residential buildings in United States. It provides a variety of ways to improve at minimal cost the indoor air quality. This standard became official on October 2003. It may be applied to both new and existing houses.

‘Indoor Climate 2002’ education and information campaign

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).

Effects of pollution form personal computers on perceived air quality, SBS symptoms and productivity in offices

The study was carried out on 30 female subjects exposed in a low-polluting office in either presence or absence of personal computers that had been in service for 3 months. Under each of the two conditions, the persons performed simulated office work using low-polluting PCs. They were found to be strong indoor pollution sources, having a negative impact on perceived air quality, on performance of office work and on some SBS symptoms.

Investigation of indoor air quality and emission of indoor used materials in Hungary

In the course of laboratory investigation we examined the adaptability of naive panels onindoor air quality measurements. We made the investigation on a measuring team of 45participants. We examined the measurement precision and standard deviation of themeasuring team with the help of Olf-Box. Our results show that despite the economicefficiency the number of persons in a measuring team cannot be reduced to less than 30subjects. We built a measuring system to examine the emission of indoor used materials.
