Feedback on full ventilation system reconditioning in a non-standard sealed building

Purpose of the work

This paper deals with the feedback of a full of a ventilation system reconditioning in a non- standard sealed building. This volume was previously retrofitted and immediately shows many difficulties to maintain good indoor air quality in some parts of the occupied volume. Indeed, a permanent well functioning of the ventilation system is essential in a sealed building without openings to ensure a good indoor air quality.

Method of approach

Developing of large building testing in Baltic countries

The purpose of the article is to introduce the condition of airtightness measurement market of large buildings in the Baltic states and in some European countries.

There are also considered national building norms of envelope airtightness and measured values.

Based on the measurement results of large buildings (more than 4,000 m3 volume according to ISO 9972-2015) the article assesses compliance of building norms of some countries with the actual building envelopes and the implementation of their controlling and stimulating functions.

Regulations and certification in Ireland

Purpose of the work

To review the impact of air tightness testing in construction in Ireland since the introduction of mandatory testing under the National Building Regulations in 2008 and the subsequent enforcement of a National Certification Scheme.

Method of approach

Review of National Building Regulations in 2008 & 2011 and implications on buildings being constructed and the industry's acceptance.

Content of the presentation

Comparison of building preparation rules for airtightness testing in 11 European countries

Mandatory building airtightness testing came gradually into force in the UK, France, Ireland and Denmark. It is considered in many other European countries because of the increasing weight of the building leakage energy impact on the overall energy performance of low-energy buildings. Therefore, because of related legal and financial issues, the building airtightness testing protocol and reporting have become crucial issues to have confidence in the test results as well as the consistency between the measurement results and values used in the energy performance calculation method.
