Volume content
Performance of a dual core energy recovery ventilation system for use in Arctic housing | 2018 | English | 10 pp
Research shows that, despite compliance with building codes, residential ventilation systems do not deliver the requested air exchanges in the individual rooms. One of the reasons for this can be found in the way the building codes are composed.
The AcouReVe Project aimed to improve the knowledge and the quality of acoustic calculation in ventilation ductworks. Such calculations are based on simplified models and the main issue is the input data.
This presentation will summarize the last forty-five years of indoor air quality (IAQ) studies, investigations and research from the first energy crisis in the USA in the 1970’s to the latest issues with regards to climate change and its effect on
French research and development activities related to conference topics by ADEME | 2018 | English | 2 pp
ADEME is a public organisation to implement public policy in the areas of the environment, energy and sustainable development.
An update on the French indoor air quality observatory recent results: focus on ventilation and perspectives | 2018 | English | 2 pp
The French indoor air quality observatory (OQAI) was set up by the French authorities in 2001 with the objective to collect data on indoor pollutants in various indoor environments to be used for public policies.
Ductwork design flaws and poor airtightness: a case study about a ventilation system reconditioning in a sealed building | 2018 | English | 10 pp
In a sealed building with tight facades, conditions for a good indoor air quality and comfortable conditions must be guaranteed all the time especially for employees.
Influence of office layout and ceiling height on vertical temperature gradient in office rooms with displacement ventilation | 2018 | English | 8 pp
An accurate temperature gradient calculation is essential for displacement ventilation (DV) system design, since it directly relates to the calculation of supply air flow rate.
Improvement of the acoustical performance of mechanical ventilation systems in dwellings: a case study | 2018 | English | 10 pp
The real performances of ventilation systems on site remains a challenge in practice. One of the most common reasons for complaints by the building occupants is the acoustic discomfort.
Noise remains a major concern for building occupants, both in their home and workplace. Ventilation system is one of the noise sources in buildings. Usually, the main issue is the resulting noise level in the room.
Rationale behind ventilation standards and regulations given by 20 countries | 2018 | English | 1 pp
International there are many different requirements and regulations for ventilation. Sometimes the variation is more than a factor of five.
Diagnostic barriers to using PM2.5 concentrations as metrics of indoor air quality | 2018 | English | 10 pp
Particulate matter with a diameter of ≤2.5µm (PM2.5) has been shown to be present in many buildings at concentrations that are harmful to human health.
How should we characterize emissions, transport, and the resulting exposure to SVOCs in the indoor environment? | 2018 | English | 11 pp
A systematic and efficient strategy is needed to assess and manage the potential risks to human health that arise from the manufacture and use of thousands of chemicals.
IAQ in working environments in Belgium: alternative approaches to CO2 requirement | 2018 | English | 7 pp
In March 2016 a new regulation came into force in Belgium regarding the wellbeing at work, with specific requirements on the indoor air quality (IAQ).
Ventilation requirements for different rooms as a result on the inquiries in 20 countries | 2018 | English | 1 pp
As a result of new inquiries in 20 countries the ventilation requirements will be presented for different rooms in dwellings, offices and schools.
Numerical and experimental identification of factors influencing the pressure homogeneity during an airtightness test in a large building | 2018 | English | 11 pp
Airtightness is the most important property of building envelopes to understand the ventilation. Airtightness refers to the flow measurement through the building envelope as a function of pressure across the building envelope.
Uncertainties in airtightness measurements: regression methods and pressure sequences | 2018 | English | 11 pp
This paper presents the results of a series of 30 fan pressurization tests in reproducibility conditions performed within a period of 10 days in October 2017. The tested unit is a newly constructed unoccupied apartment in Brussels.
Experimental Investigation of the Impact of Environmental Conditions on the Measurement of Building Infiltration, and its correlation with Airtightness | 2018 | English | 11 pp
The air infiltration of a building, which fundamentally depends on its airtightness, can be a significant contributor to its heat loss.
Experimental study of enclosure airtightness of an outdoor chamber using the pulse technique and blower door method under various leakage and wind conditions | 2018 | English | 11 pp
This paper introduces an experimental study of enclosure airtightness testing of an outdoor chamber using both the pulse technique and the blower door method.
Since the 1970s, many authors have discussed the impact of poor airtightness on building energy use, indoor air quality, building damage, or noise transmission (Carrié and Rosenthal, 2008) (Tamura, 1975) (Sherman and Chan, 2006) (Orr and Figley, 1
