Twenty three papers from the ninth AIVC Conference, titles as follows: Keynote speech: Air Infiltration and Ventilation; Natural airflows between roof, subfloor and living spaces; Experimental analysis of air diffusion in large space; Determinatio
Air quality and draught avoidance are fairly important to office staff; consequently, the occupant's perspective should be taken into account when assessing the relative merits of different methods of ventilation in office buildings.

General background to the conference.
Colla M
The National Institute of Standards and Technology (formerly the National Bureau of Standards) has through an interagency agreement with the Public Building Service of the General Services Administration performed an evaluation of the thermal and
Grot R A, Persily A, Hodgson A T, Daisey J M
The ventilation and leakage characteristics of suspended floors are not well documented.
Lilly J P, Piggins J M, Stanway R J
More than two months of detailed test data have been gathered using modified constant concentration tracer gas techniques for a six-storey, 60 apartment, multi-family building.
Harrje D T, Bohac D L, Feuermann D
Numerical modelling is performed for three-dimensional turbulent buoyant flows emerging from an air diffuser in an air-conditioned, ventilated room.
Fang J B, Grot R A, Kurabuchi T
Experimental investigations concerning energy savings achieved in buildings with passive solar components (e.g. large south-front windows, sunspaces or Trombe walls) have already been effected under test conditions.
Erhorn H
In this paper a short term testing methodology is developed to evaluate the performance of ventilation systems with respect to control of indoor air pollutants.
Anderson R
The Dutch Standard NEN 1087 "Ventilation of dwellings": Requirements (1) is at this moment under review. A requirement can be found about the quality of air. In fact a statement is made that outside air is required as fresh air for bedrooms.
De Gids W F, Phaff J C
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
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
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
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
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
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
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.
