The aim was to develop a multiple logistic regression model to identify multi-family houses with an increase of sick building syndrome (SBS). In Stockholm, 609 multi-family buildings with 14,235 dwellings were selected by stratified random sampling. The response rate was 77%. Multiple logistic regression analysis was applied, adjusting for ownership of the building, building age and size, age, gender, and atopy. Females, subjects with allergy, those above 65 yr, and those in new buildings reported significantly more SBS.
No more will weatherization crews find their hands tied when they see opportunities for energy savings in every corner-the Weatherization Plus plan will open the door to bring home advanced technologies.
The present paper refers to the numerical prediction of air velocities and temperatures inside single-sided naturally ventilated buildings and more specifically the special case in which air from the external environment is brought into the building through single-directed openings. The work is focused on the physical procedures governing air movement during the single-sided natural ventilation.
The energy and mass flows required to sustain dwelling services can be established and quantified only within the framework of a stock and flow model of the total housing stock. This paper develops such a model to estimate the energy flows of a typical sub-population of New Zealand housing stock. The energy and mass flows of key building materials are estimated and the energy flows of alternative cladding systems are compared. The stock and flow model is driven by empirical schedules of mortality.
This study examines the influence of ventilation on chemical reactions among indoor pollutants. We have used a one compartment mass balance model to simulate unimolecular and bimolecular reactions occurring indoors. The initial modeling assumes steady-state conditions. However, at low air exchange rates, there may be insufficient time to achieve steady-state. Hence we have also modeled non steady-state scenarios. In the cases examined, the results demonstrate that the concentrations of products generated from reactions among indoor pollutants increase as the ventilation rate decreases.
Maior problems exist with the way some attic insulations are manufactured, labeled, and installed. An experienced insulation contractor, diagnostic technician, and building science educator sizes up the ongoing problem of cheating and offers specific recommendations to prevent it.
The cross-sectional questionnaire-based study was conducted in spring 1998 among indoor workers of 6 buildings in town Tartu, Estonia. The goal of this pilot study was to evaluate magnitude of possible problems related to indoor air quality in Estonian nonindustrial workrooms as well as in those workers' dwellings. Therefore, the questionnaire included questions about perceived indoor environment for both workplaces and homes.
