33rd AIVC conference – 2nd TightVent conference
Optimising Ventilative Cooling and Airtightness for
[Nearly] Zero-Energy Buildings, IAQ and Comfort
Copenhagen, Denmark, 10-11 October 2012
In cooperation with
The joint ’33rd AIVC Conference‘ and ’2nd TightVent Conference’ aimed to focus on ventilation and infiltration in nearly zero-energy buildings and more particularlyon challenges and perspectives for ventilative cooling (the use of ventilation systems to cool indoor spaces) as well as the rationale and solutions for better building and ductwork airtightness.
Ventilative cooling strategies, as part of an overall design strategy including adequate solar protections, thermal mass and active cooling, can help improve thermal comfort. Their potential is more and more considered to reduce the cooling energy demand in summer or mid-season conditions, depending in particular on outdoor climate, building design and internal loads.
At the same time, ventilation as well as envelope and ductwork airtightness remain a specific challenge for new or renovated very low-energy buildings as they can represent over 50% of a building’s total space heating (or cooling) needs. Besides, their share often increases with increasing energy performance.
To address these issues, the aim of this conference was to present and foster new research and development, applications and market transformation with a specific focus on ventilative cooling strategies as well as envelope and ductwork airtightness, two aspects that are particularly relevant in the trend towards nearly zero-energy buildings.
The conference was organized by the International Network on Ventilation and Energy Performance (INIVE) on behalf of the Air Infiltration and Ventilation Centre (AIVC) and TightVent Europe, the Building and Ductwork Airtightness Platform.
Since 1980, the annual AIVC conferences have been the meeting point for presenting and discussing major developments and results regarding infiltration and ventilation in buildings. AIVC contributes to the programme development, selection of speakers and dissemination of the results.
The TightVent « Building and Ductwork Airtightness Platform », which was launched January 1, 2011, aims at facilitating exchanges and progress on building and ductwork airtightness issues, including the organization of conferences, workshops, webinars, forums, etc.
Contributions were invited in the areas of research, development, application and market and legislative implementation of ventilation and infiltration. Preference was given to abstracts focusing on one of the following topics:
For ventilative cooling aspects:
- Potential for ventilative cooling strategies
- Design approaches for ventilative cooling and case studies
- Ventilative cooling in energy performance regulations
- Summer comfort and ventilation
For airtightness related aspects:
- Product and method developments for envelope and ductwork airtightness
- Best practice and case studies
- Quality management approaches for envelope and ductwork airtightness
- Airtightness issues in existing buildings
- Energy and IAQ impact of envelope and ductwork leakage
- Ventilation and infiltration in mild climates
For other ventilation aspects:
- Innovative ventilation concepts and combined systems
- Demand-controlled ventilation
- Humidity control and moisture damage
- Ventilation and thermal comfort, and infiltration in nearly zero-energy buildings
The conference was held in downtown Copenhagen (Denmark), in the Axelborg building, http://www.bojesen.dk/BOJESEN-AT-AXELBORG.95.aspx
