The influence of a controlled natural ventilation on the indoor radon decay products concentration: a case study. | 1988 | English
Air exchange rates in occupied buildings are difficult to assess due to their dependence on a multitude of climatic parameters and inhabitant behaviour.
Numerical simulation of indoor turbulent air flows caused by cross-ventilation and its model experiments. | 1988 | English
Since thermal comfort on human body is influenced by the local air flow speed, it is needed to estimate the distribution of air flow speed in a room for the "effective ventilation".
The paper presents the development of a ventilation scheme for a large bus station and passenger interchange in Bilbao, Spain.
This paper is concerned with natural air flows between major construction cavities in New Zealand houses.
Analysis of errors for a fan-pressurization technique for measuring interzonal air leakage. | 1988 | English
The problem of predicting air flows in a multi-zone building has received considerable attention in the past ten years.
To avoid the shortcomings and problems that occur in today's ventilation systems a ventilation concept for future dwelling-houses is under development. The concept responds to the way of living and building in the future.
Zone to zone tracer gas measurements; laboratory calibration and values of air flows up and down stairs in houses. | 1988 | English
This work is concerned with measuring air flows between the floors of houses. A simple measuring technique is described in which two portable SF6 systems were employed. The design and construction of the portable system are presented.
Natural ventilation for crown court: developing statistical assessment techniques at the design stage. | 1988 | English
The ventilation performance of a proposed naturally-ventilated court-room was predicted and assessed on a statistical basis with regard to the local meteorological conditions.
A unique multiple tracer experimental system has been developed and utilized within commercial buildings to monitor ventilation rates, air exchange efficiency, ages of air (at multiple indoor locations), flow rates of supply and outside air, and p
Infiltration heat losses due to heating appliances located within the living space are normally evaluated by reducing the conversion efficiency of the boiler, with no consideration for the fluid dynamic interaction between boiler, chimney and buil
This paper presents an analysis of indoor climate in buildings with forced air heating systems. The results is based on indoor climate measurements and extensive interviews with the occupants.
This paper deals with field experience of airborne moisture transfer problems in houses. Two types of phenomena are discussed in more detail; the infiltration of moist air from crawl spaces and the propagation of moist air produced in kitchens.
In displacement ventilation systems, air flow rates, temperature and the design of the air supply device strongly influence the parameters which decide the thermal comfort.
The specific value of different flows resulting from air exchanges between rooms or with the outside is not always important. An extensive model is not suitable when only estimations or tendencies have to be drawn (very time consuming).
The paper describes measuring results of the air movement from three different types of diffusers for displacement ventilation. Two of the diffusers are lowlevel wall mounted diffusers, one with a low and one with a high initial entrainment.
This paper reviews research activities undertaken in the framework of IEA Annex XIV, "Energy and Condensation". It outlines the objectives and working scheme.
Outdoor air pollution can have a bearing on the effectiveness of indoor air and the quality of ventilation. There is a pressing need to reflect on the potential type and effect of occurrences (e.g.
An element-assembly formulation of multi-zone contaminant dispersal analysis theory is described.
This paper tries to give a reasonable description of the state of the art of the Belgian building stock with regard to ventilation.
