Volume content
Twenty five cellular offices in the Wilkinson Building at the University of Sydney, Australia are ventilated through operable windows and doors and have…
This paper is based on the results of Subtask B of the HybVent Project. It presents a critical review of the literature and recent developments in analysis…
Calculations using CFD are presented for adventitious openings in which the flow is not fully developed. It is shown that the quadratic equation performs…
Measurements of metabolic carbon dioxide concentration made in four classrooms in two schools are reported for both occupied and unoccupied periods.…
In the following, measurements of CO2 levels in seven classrooms in four schools are reported. Measurements were taken for approximately one week in each…
Results of a CFD simulation of the wind-assisted stack ventilation of a single-storey enclosure with high and low-level ventilation openings are presented…
The paper presents examples of hybrid ventilation and control strategies in office and educational buildings from the IEA ECBCS Annex 35 HybVent case…
Using the wind pressure difference method to estimate the cross ventilation potentials of a building at a particular site, the appropriate wind frequency…
Ventilation is one of the most important measures to dilute indoor air pollutants. In order to maintain a clean indoor air environment, not only the total…
The use of ceiling mounted circulating fans to provide air movement for cooling in industrial premises and animal houses is particularly essential in warm,…
Climatisation and natural ventilation concepts are today, in most countries, considered to be an essential aspect of the building project. In fact they are…
A hybrid ventilation system combines both mechanical and natural ventilation modes. The natural ventilation mode, especially, causes some challenges for…
In the design of natural ventilation systems, there is a wide range of possibilities with regard to the selection of window type and the positioning of…
This paper focuses on hybrid ventilation performance in an office building. It presents measurement results from the new headquarters of the company Bang…
This paper reports the results of computer simulations of a hybrid-ventilated building using ESP-r (Environmental Systems Performance for research). A new…
This paper describes the development of a simplified tool which should be used at the early design stage for predicting air ventilation rates in a building…
This study, which formed part of the Annex 35 Hybrid Ventilation in New and Retrofitted Office Buildings project, was completed at LEPTAB and supported by…
The demand for buildings with high quality indoor environments is growing, especially in developing countries, where more and more energy will be consumed…
The basic mechanism for natural ventilation in a building involves air flowing through purpose-made ventilator openings. These ventilators must be carefully…
Buildings are aired to evacuate indoor pollutants, in particular those produced by the occupants. CO2 is a good indicator of occupancy, as long as there is…
