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.
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
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.
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.
Use of the global warming potential index to evaluate the impact of reducing air infiltration rates in existing houses. | 1999 | English
In a cold climate such as of Montreal the air infiltration through the exterior envelope of a house has a significant impact on the heating energy consumption and cost.
Energy loss due to ventilation: impact of average values and simplifications on calculations. | 1999 | English
The project of CEN Standard from the Ventilation for dwellings group TC156/WG2/AH4 [1]for airflows calculations is being submitted to enquiry.This method can be easily compared to AIVC guides to calculate the ventilation airflow(natural or mechani
Chinese food is delicious. There are many kinds of cuisine. But the stir-fry, fry and deep-fry produce a large amount of steam and smoke which cause indoor air pollution seriously. So it must be controlled.
Appraisal of building envelope alternatives in terms of overall physical performance. | 1999 | English
The envelope as fictional building element acts as a filter intended to regulate energy andmass flows. The overall performance of the envelope is ascertained by the combined effects ofthe functional components.
The U.S.
Comparison of indoor air quality between air-conditioned building and naturally ventilated building during heating season. | 1999 | English
Field measurements were made during the heating season to compare IAQ between an air– conditioned building (Building A) and a naturally ventilated building (Building B) situated in the centre of Pyongyang and similar in architectural design, numbe
The energy saving practice of stopping ventilation systems at night may reduce the daytimeair quality.
The improvement of air quality due to self-restricted air consumption in regions as well as globally appears to have considerable promise.
The purpose of this study is to provide a model to facilitate the simulated evaluation of theenergy consumption for different mushroom house and climate set point configurations.Climate management in this application is complex, including control
Three buildings are investigated to study the indoor air quality and the impact of the outdoorair pollution. These buildings, a swimming pool, a school and a nursery are located in anurban area.
Two energy-efficient single-family houses (known as ESPI houses) with competitive overallcosts were set up during the study in Finland.
Rooms with high windows are likely to have comfort problems caused by cold airdowndraught, which are usually solved by placing heating appliances underneath thewindows.
This study aims to introduce a methodology which enables to revise the limit values of overallheat transfer coefficient in accordance with the building form from thermal comfort andenergy conservation point of view.In order to prevent excess heat
Low temperature heating systems: impact on IAQ, thermal comfort and energy consumption. | 1999 | English
The Netherlands Agency for Energy and the Environment(NOVEM) is conducting a program for the implementation of Low Temperature Heating (LTH) systems in buildings. The primary goal is to enable the use of Low Talued Energy as a heating source.
