Evaluation of domestic ventilation system performance by COMIS model for Japanese conditions. | 1999 | English
Individual thermal comfort control with desk-mounted task / ambient conditioning (TAC) systems. | 1999 | English
Three very different task/ambient conditioning (TAC) systems were investigated in a climate chamber.
A methodology to assess the IAQ performances of ventilation systems in residential buildings. | 1999 | English
Until now, there is no widely accepted way to express any index for this purpose and takinginto account the large variety of possible pollutants.
Investigation the modelling of the mathematical model of expediency of project decisions of building materials including the human safety the asbestos. The asbestos is most widely used in the production of roof cover-slate.
Recent years have brought the popularity of methods in which neutral networks are applied. They seem of particular importance while dealing with diagnosing, predicting and estimating.
Combined control of natural and forced ventilation using intelligent control algorithms. | 1999 | English
Results are presented from a study of the performance of fuzzy, rule-based algorithms for thecontrol of indoor air quality through combined control of natural and forced ventilationstrategies, whilst simultaneously meeting thermal and visual comfo
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.
Development of a demand control strategy in buildings using radon and carbon dioxide levels. | 1999 | English
Air change rates, indoor radon and carbon dioxide levels were monitored in a lecture theatre in the Hong Kong University of Science and Technology.
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.
