The airtightness of buildings is important for several reasons, such as being a prerequisite for low-energy buildings and for a healthy indoor air quality (without i.e. mould or radon).
38th AIVC - 6th TightVent - 4th venticool Conference - Nottingham, UK - 13-14 September 2017
The 38th AIVC Conference "Ventilating healthy low-energy buildings", was held in Nottingham, UK, 13-14 September 2017. Contains 113 papers and summaries.
Air leakage variations due to changes in moisture content in wooden construction - magnitudes and consequences | 2017 | English | 11 pp
Towards the definition of an indoor air quality index for residential buildings based on long-and short-term exposure limit values | 2017 | English | 10 pp
In the Framework of the IEA EBC Annex68 Subtask 1 working subject, we aimed at defining an indoor air quality index for residential buildings based on long- and short-term exposure limit values.
Development and measurement results of a compact Counterflow Heat Recovery Fan for single/double room ventilation | 2017 | English | 8 pp
With the combination of two fans and a heat exchanger in one single component there is the possibility to design a compact and highly efficient ventilation system especially for use in building modernization.
When considering the performance of HRV systems, the discussion is generally focusing on the reported effectiveness of the air-to-air heat exchanger.
Methodology for assessing the air-exchange performance of residential ventilation systems | 2017 | English | 9 pp
Residential ventilation standards, especially in Europe are slowly but substantially moving away from their usual prescriptive approach towards performance based specifications.
TVOC concentrations measured in Belgium dwellings and their potential for DCV control | 2017 | English | 8 pp
Over the last decade, TVOC sensors have been touted as an interesting alternative to CO2 and RH sensors in DCV systems. Nevertheless, there is little evidence on the nature and the profile of TVOC concentrations in modern dwellings.
Technologies to overcome effects of condensation in exchangers of ventilation units - analysis of monitored field studies | 2017 | English | 5 pp
Balanced ventilation with heat recovery is an efficient way to maintain low heating demand for ventilation in residential buildings.
Experimental study on the in-situ performance of a natural ventilation system with heat recovery | 2017 | English | 10 pp
Combining heat recovery with natural ventilation is a relatively new topic of significant academic and commercial interest.
Impact assessment of natural ventilation on thermal comfort levels in sustainable residential buildings | 2017 | English | 11 pp
In the present paper the impact of natural cross-ventilation on thermal comfort levels in sustainable residential buildings is evaluated.
Possible UK residential demand-controlled ventilation assessment methodology | 2017 | English | 11 pp
Demand controlled ventilation (DCV) can improve the energy performance of all kinds of ventilation systems, in residential and non-residential buildings and is already part of the European Lot 6 and Ecodesign regulations and standards.
The influence of occupancy behaviour on the performance of mechanical ventilation systems regarding energy consumption and IAQ | 2017 | English | 10 pp
It has already been proven that a large portion of the energy consumption gap between simulations and reality is due to the occupant behaviour in buildings.
Noise from domestic ventilation systems is currently a little understood problem in the UK. Other European countries that have a longer history of using mechanical domestic ventilation systems have introduced noise limits for these systems.
Challenges of using passive ventilation to control the overheating of dwellings in noisy environments | 2017 | English | 13 pp
Where residential developments rely on opening windows to control overheating, there can be a compromise between allowing excessive noise ingress with windows open, or excessive temperatures with windows closed.
Advanced airflow distribution methods for reducing exposure of indoor pollution | 2017 | English | 6 pp
The adverse effect of various indoor pollutants on occupants’ health have been recognized.
Investigation of future ventilation flow rate requirements for dwellings in Belgium: from the application of FprEN16798-1:2016 to proposed robust rules | 2017 | English | 10 pp
In the context of the PREVENT project, preparing a possible revision of the Belgian residential ventilation standard, the way of expressing ventilation requirements, among others in terms of ventilation flow rates, needs to be investigated.
Ventilation systems play an important role in providing a good indoor air quality in dwellings. Mechanical exhaust ventilation systems implement natural vents to supply outdoor air to the dwelling. Natural driving forces, i.e.
The future of hybrid ventilation in office buildings – energy simulations and lifecycle cost | 2017 | English | 12 pp
This study presents a comparison of three ventilation systems; automated Natural Ventilation (NV), balanced Mechanical Ventilation (MV) with heat recovery and Hybrid Ventilation (HV) with heat recovery for a new build office building.
Hybrid ventilation in new and refurbished school buildings – the future of ventilation | 2017 | English | 12 pp
More than 64 million pupils spend more time in school than in any other place except home in Europe (European Commission, 2014).
Cool materials in the urban built environment to mitigate heat islands: potential consequences for building ventilation | 2017 | English | 10 pp
Urban warming, commonly referred to as the ‘Urban Heat Island’ phenomenon (UHI), is a well-established effect that affects cities all over the world.
Exposures to airborne fine particulate matter with a diameter of <2.5μm (PM2.5) are linked to multiple negative health effects, including cardiovascular and respiratory disease.
