13th International BUILDAIR-Symposium 2023 [AIVC endorsed]

The 13th International Buildair Symposium will take place on June 2nd and 3rd, 2023 in Hanover. As always, this bilingual industry forum – all presentations and discussions will be interpreted simultaneously – will offer an attractive and highly informative conference program. A trade show will run parallel to the conference.

Experts from eight countries will talk about their current projects, present new methods and research results, and report on lessons learned with unusual projects.

12th International BUILDAIR-Symposium 2021 [AIVC endorsed]

The 12th International BUILDAIR Symposium will take place on June 25 and 26, 2021 – as a bilingual online conference, in view of the corona situation. The meeting again offers an ambitious programme. Among other things, the presentations will deal with measuring techniques, gluing and sealing difficult details, minimizing the air permeability of materials, quality assurance for very technology-intensive objects and measuring technology for very tall buildings.

Estimation of Air Leakage Sizes in Building Envelope using High-Frequency Acoustic Impulse Response Technique

Heating energy in buildings represents a significant proportion of the total global energy consumption. Uncontrolled airflow through the building envelope contributes significantly to its energy losses.  

New findings on measurements of very airtight buildings and apartments

The trend in European countries, such as Belgium, France and Germany is that the quality of the airtightness of the building envelope is getting better and better. This is true for small, airtight apartments, Passive houses and some large buildings with an excellent airtightness due to special requirements, e.g. oxygen reduction or fire protection.

An investigation of ventilation control strategies for louver windows in different climate zones

Guaranteeing high indoor air quality and high degree of user satisfaction at the same time is one of the challenges when improving the energy efficiency of a building. Current non-residential buildings mainly use mechanical ventilation systems to ensure high air quality. Mechanical ventilation systems are known for minimising heat losses but at the same time lead to higher installation, operating and maintenance costs. Furthermore, mechanically conditioned rooms may lead to the sick building syndrome caused by the lack of operable windows.

24-25 May 2019, Hannover – “11th International BUILDAIR Symposium”

AIVC is pleased to announce the eleventh anniversary of the International BUILDAIR Symposium “Airtight Buildings, Thermography and Ventilation Systems in Practice” to be held on May 24-25, 2019 in Hannover Germany.

Influence of night ventilation on the cooling demand of typical residential buildings in Germany

The current type of construction preferred for new high energy efficient buildings in Germany, featuring highly insulated building components and an almost completely airtight building shell, raises several new challenges with regard to design, construction and use of these buildings. Cooling, in particular, is an issue that gains importance also in the residential sector, in connection with rising temperatures induced by the climate change.
