The main objective of this study was to determine the ventilation demand for a gymnasium inthe primary school based on verified metabolic rate.Norwegian guidelines recommend 6.0met as the activity level to be used when calculating the outdoor air
The Paper deals with numerical computations, carried out, in order to predict the effects of natural convection on the thermal performance of porous material.
Prediction of air flow in a single-sized naturally ventilated test room using artificial neural networks. | 1999 | English
The objective of this research is to investigate thermal comfort and air flow distribution insidea test room which is naturally ventilated. The test room is ventilated through adjustablelouvers.
Surveys on repressurization-induced backdrafting and spillage were conducted in threedifferent areas of the United States using a common protocol, primarily to assess thecorrespondence between short-term tests and one week of continuous monitoring
The objectives of thisinvestigation were to examine the dynamic water vapour sorption offurnishing materials and to compare the experimental results withpredictions obtained from the Moisture Admittance Model.
Experimental and numerical investigation on temperature and air velocity distribution in a room equipped with split-system air conditioner. | 1999 | English
Split-system air conditioning is increasingly usedapplications, owing to its low cost and installationboth for residential and commercialease.
The air quality in a subway-train was studied to suggest optimal design criteria and operationconditions based on the ventilation demand by passengers. The C02 emitted from thepassengers was the tracer for this study.
Evaluation of temperature distributions and airflow patterns with three air diffusing systems in heating period. | 1999 | English
This study is to investigate the characteristics of indoor air temperature distributions and airflow patterns with three air diffusing systems in heating period and to find the methods which can predict those indoor environmental conditions effect
Comparison of mechanical and natural ventilation using long-term evaluation model for indoor air quality, thermal environment, and energy consumption. | 1999 | English
There are often tradeoffs among improving IAQ (Indoor Air Quality), maintaining thethermal comfort, and reducing energy consumption for HVAC (Heating, Ventilating, and Air-Conditioning) systems.
Within an International Energy Agency (IEA) project (Annex 27) experts from 8 countries(Canada, France, Italy, Japan, The Netherlands, Sweden, UK, and USA) have developed toolsfor evaluating domestic ventilation systems during the heating season.
Prediction of the indoor air quality trend in a dwelling in the Mediterranean climate. | 1999 | English
The purpose of this study was to evaluate the indoor air quality parameters in a residentialdwelling using information from the field.
Evaluation of the effects of ventilation systems on temperature, humidity, air quality and energy consumption in multiple dwellings. | 1999 | English
Recently well-insulated and well-airtightened houses are increasing in Japan. Those houses havesome problems of air quality because of formaldehyde from construction materials. Ventilationsystems have possibility to solve these problems.
A study on the characteristics of indoor environment and comfort in office building with underfloor air-conditioning (UFAC) system. | 1999 | English
During the last decade, an increasing interest in Underfloor Air-Conditioning (UFAC) systems has emerged. This is due mainly to an increased demand from employees for a greater control over their working environment.
In this paper, analysis of the ventilation requirements of enclosed vehicular parking facilities is discussed. First, a compilation of existing U.S.
Application of statistical experimental design for parametric simulation studies in building physics, with an emphasis on indoor air. | 1999 | English
Parametric studies have often been used for sensitivity analyses in the field of the pharmaceuticaland agricultural sector.
Performance evaluation of a displacement ventilation system for improving indoor air quality: a numerical study. | 1999 | English
To evaluate the performance of a ventilation system, the local mean age of air has usually been used to estimate how efficiently fresh air is diffused to a desired location.
Comparison of modelled and measured tracer gas concentrations in a multizone building. | 1999 | English
Few detailed comparisons of modeled ad measured pollutant concentrations in multizonebuildings have been published.
The influence of air supply and exhaust locations on ventilation efficiency and contaminant exposures in rooms. | 1999 | English
An efficient ventilation system is characterised by a well-organised and turbulence-controlled airstream that rapidly corrects disturbances in air quality and thermal comfort in the ventilated space.Air supply and exhaust conditions are investigat
Based on concerns about indoor air quality and trends towards tighter envelope construction,there has been increasing interest in mechanical ventilation of residential buildings in the UnitedStates.
