An element-assembly formulation of multi-zone contaminant dispersal analysis theory is described.
Axley J
In the past few years, research efforts have been made to acquire accurate knowledge about infiltration and ventilation in multi-zone buildings.
Furbringer J M, Roecker C, Roulet C A
This text contains comments to the poster presented at the 9th AlVC Conference in Gent, Belgium.
Hertig J A, Ehinger J
In the framework of a project of the International Energy Agency (IEA) , IEA-Annex XVIII - Demand Controlled Ventilating (DCV) Systems, which started in fall 1987, a review of the state of the art of already existing DCV systems and devices has be
Raatschen W
An experimental study in reduced scale model for ventilation inside a sheep-fold has been studied.
Fissore A, Nusgens P
A constant concentration tracer gas (CCTG) measuring system needs a control algorithm to calculate, at each sampling time, the required tracer gas injection rate to keep the gas concentration at a target level.
Compagnon R, Kohler A, et al
The technique of tracer gas measurement has during recent years tended towards increasingly complicated measuring methods.
Kvisgaard B, Collet P F
Mechanical ventilation systems have been adopted in airtight energy- efficient houses in Canada to provide fresh air, remove moisture and indoor pollutants and provide a comfortable environment for the home-occupants.
Riley M, Piersol P
The ventilation of a test room (LxWxH = 5.4x3.6x2.4 m) with a wall mounted heat source is investigated for two different air terminal devices.
Heiselberg P, Nielsen P V
Increases in building air tightness for purposes of energy saving have, unfortunately, also led to a significant increase in the number of instances of condensation damage, particularly in domestic properties.
Edwards, R E, Irwin C
Tracer gas techniques for measuring airflow rates in building systems are considered.
Axley J, Persily A
Air leakage through the building envelope is of great importance for the energy use of a building. However, from an indoor air quality standpoint, the size of interior leaks in e.g. multifamily buildings could be important as e.g.
Levin P
This work deals with problems of the air humidity in inhabited dwellings. A new approach is presented here which renders the definite diagnosis of humidity problems possible.
Schmickler F P
Traditionally air has been supplied from the ceiling to the occupants below opposing the buoyancy effects due to heat convected from people, lights and machines.
Croome D J
Ventilation produced by fluctuating pressure differences across a building appears to have received little attention . Such fluctuations are produced by gustiness of the wind or turbulence in the flow around a building.
Sahin B, Clark C, et al
This paper describes a two-dimensional numerical study, by finite-volume method of buoyancy-driven flow in a half-scale model of a stairwell.
Zohrabian A S, Mokhtarzadieh-Dehghan M R
The project is aimed to develop the quantitative method of visualization of the air steams in application to the indoor problems of heauilg , ventilating and air conditioning.
Gottschalk G, Tanner P A, Suter P
Air exchange rates in occupied buildings are difficult to assess due to their dependence on a multitude of climatic parameters and inhabitant behaviour.
Crameri R, Schuler Ch, et al
The paper presents the development of a ventilation scheme for a large bus station and passenger interchange in Bilbao, Spain.
Holmes M J, Salusbury T
This paper is concerned with natural air flows between major construction cavities in New Zealand houses.
