AIVC publication

In March 2017, AIVC identified smart ventilation for buildings as a new and important topic to be addressed.

Several actions were defined by AIVC Board about this topic in order to exchange and disseminate information on this topic. A working group of AIVC experts from several countries was created. One of its tasks was to agree on a definition of smart ventilation.

The purpose of this ventilation information paper is to present and illustrate this definition of "smart ventilation".

The objective of present work was to develop the metric that assess the performance of solutions securing high indoor air quality in low-energy (modern) residential buildings. This was achieved by summarizing data on the levels and types of gaseous pollutants and particulate matter in low-energy buildings and comparing them with the existing exposure limits for pollutants.

Because buildings are responsible for 40% of energy use and 36% of Greenhouse Gas (GHG) emissions in the EU, energy efficiency in buildings has become a priority to drastically reduce the energy use in buildings. Consequently, a number of policy measures have been implemented in European Member States to drive the market towards Nearly Zero-Energy Buildings, including the Energy Performance of Buildings Certificates (EPCs), which are the most visible instrument of the Energy Performance of Buildings Directive (EPBD).

This Ventilation Information Paper analyses both the policy instruments used (regulatory requirements and incentives, specific programme requirements, quality frameworks for testers and builders) and the changes observed in practice in terms of building and ductwork airtightness over the past 5 years, using as reference mostly publications from AIVC and TightVent led events. Although we have not restricted our literature review to specific parts of the world, the majority of the publications we found come from Europe and the USA.

This report summarises the outcome of the work of the initial working phase of IEA ECB Annex 62 Ventilative Cooling and is based on the findings in the participating countries.

The objective of this study was the development of a new test method for portable indoor air cleaners.

There exists a significant body of literature on energy and indoor air quality impacts of envelope leakage. In fact, this topic has been studied since the 70s and has lead to many publications, in particular within the Air Infiltration Centre established in 1979 that has become the Air Infiltration and Ventilation Center (AIVC) since 1987.

This study is about the effectiveness of the indicated ventilation measures in the day-to-day operations of three types of hospitality businesses:
-           a pub not serving meals (drinking pub)
-           a pub serving full meals (dining pub)
-           a discotheque
