TN 68: Residential Ventilation and Health

Exposures in homes constitute the major part of exposures to airborne pollutants experienced through the human lifetime. They can constitute from 60 to 95% of our total lifetime exposures, of which 30% occurs when we sleep.

New release! AIVC Ventilation Information Paper #43: Residential ventilation and health

We are happy to announce the release of AIVC's Ventilation Information Paper no 43: Residential ventilation and health. This paper briefly presents the key outcomes of the AIVC Technical Note 68 (TN 68) "Residential Ventilation and Health”, in an effort to ease the dissemination of this key AIVC publication. The document starts with an overview of pollutants in domestic dwellings that have been measured, prioritizes pollutants for mitigation in the indoor environment and identif

VIP 43: Residential ventilation and health

AIVC Technical Note 68 (TN 68) "Residential Ventilation and Health” is one of the outcomes of the work performed under the framework of AIVC’s project “Ventilation & Health” and benefited from contributions by several authors and many structured discussions held during specific sessions at AIVC events. TN 68 summarised studies that prioritise pollutants in the indoor environment and presented a

Potential of mechanical ventilation for reducing overheating risks in retrofitted Danish apartment buildings from the period 1850-1890 – A simulation-based study

Advancing energy efficient renovation solutions in buildings necessitate adopting high-insulation and airtightness to avoid heat loss through transmission and infiltration, which can result in overheating. Elevated indoor temperatures have a highly negative effect on building occupants’ health, wellbeing and productivity. With the possibility of remote working, people spend more time at home, and therefore addressing the elevated indoor temperatures and the overheating risks in residential buildings proves to be essential.

Energy analysis for balanced ventilation units from field studies

Balanced ventilation units are well known to provide a sufficient amount of fresh air in residential buildings in a controlled way, without relying on ever-changing naturally driven forces. During colder periods, heat recovery ensures a reduction of the ventilation heating load. Outside the colder periods, recovery is reduced or shut off automatically, providing mechanical ventilative cooling. During warmer periods, the recovery is used again to provide a comfortably cool supply of fresh air.

Technologies to overcome effects of condensation in exchangers of ventilation units - analysis of monitored field studies

Balanced ventilation with heat recovery is an efficient way to maintain low heating demand for ventilation in residential buildings. Laboratory measurements of today’s heat recovery ventilation units show high temperature recovery efficiency during standard conditions. In practice, however, the recovery efficiency may decrease due to circumstances that deviate from the standard laboratory conditions.

Investigation of future ventilation flow rate requirements for dwellings in Belgium: from the application of FprEN16798-1:2016 to proposed robust rules

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. The aim of this paper is to propose and compare ways of expression of the ventilation requirements in terms of flow rates with respect to their robustness across dwellings.

Design and operation of ventilation in low energy residences – A survey on code requirements and building reality from six European countries and China

One of the key objectives of the IEA Annex 68 research programme entitled “Indoor Air Quality Design and Control in Low Energy Residential Buildings” is to provide a generic guideline for the design and operation of ventilation in residential buildings. They need to have minimal energy consumption, and at the same time maintain a high level of Indoor Air Quality (IAQ). The paper reports on preliminary results of an interview survey conducted among different stakeholders involved in design, installation and operation of residential ventilation in countries involved in the Annex.

Primary energy used in centralized and decentralized ventilation systems measured in field tests in residential buildings

Ventilation systems can save heat energy by using heat recovery, but consume electrical energy to power the fans. In practice, the energy efficiency of those systems can be lower than expected, when compared to the nominal values provided by the manufacturer. In this paper, results of a comprehensive field tests with 20 centralized and 60 decentralized ventilation systems for residential buildings and the calculation of the primary energy savings of those devices are presented.
