The 36th AIVC Conference "Effective ventilation in high performance buildings" will be held together with the 5th TightVent and 3rd venticool conferences.
The conference will start on Wednesday September 23, 2015 at 09:00hrs and will end on Thursday September 24, 2015 at 17:30hrs. The full programme will be available by the end of August 2015.
The conference will consist of 3 parallel tracks:
- One track will be devoted to airtightness issues;
- One track will be devoted to ventilative cooling and thermal comfort;
- One track will be devoted to ventilation, indoor air quality and health.
The conference will include:
- Plenary sessions;
- Topical sessions (sessions structured around a specific topic);
- Long and short oral presentations from call for papers.
- Receipt of abstracts (extended deadline): April 15, 2015

The building sector plays a key role to be successful in achieving ambitious goals to reduce energy use and greenhouse gas emission. The development and revision of energy performance of buildings regulations as well as the implementation of pilot high performance building programmes reflect the growing awareness regarding the abatement potential in this sector.
However, one key concern regards provisions taken in practice to maintain acceptable indoor environmental quality while taking measures to reduce buildings’ energy use. Specifically on ventilation and infiltrations issues, indoor contaminants should be contained within acceptable limits for the health and comfort of the occupants. The overheating risk should be addressed with appropriate management of solar loads, airflow rates and thermal mass. Air infiltration losses should be minimized.
Fortunately, these challenges can be overcome in practice in conventional and in high performance buildings. However, building designs aiming for high performance are often more sensitive than conventional buildings to mistakes and inappropriate provisions for energy conservation and indoor climate. Therefore, the joint 36th AIVC, 5th TightVent and 3rd venticool Conference aims to focus on effective ventilation in high performance buildings, with the following major themes:
- Thermal comfort and ventilative cooling—i.e., the application of ventilation airflow rates to cool indoor spaces and avoid overheating in buildings;
- Air infiltration through leaks in the building envelope and ductwork;
- Ventilation in relation to Indoor Air Quality and health.
The conference is an initiative from:
- the International Network on Ventilation and Energy Performance (INIVE) on behalf of the Air Infiltration and Ventilation Centre (AIVC), TightVent Europe (the Building and Ductwork Airtightness Platform), and venticool (the international platform for ventilative cooling); and
- The Eduardo Torroja Institute for Construction Science - IETcc-CSIC
Contributions are invited in the areas of research, development, application and market and legislative implementation of ventilation and infiltration. Preference will be given to abstracts focusing on one of the following topics:
For ventilative cooling aspects:
- Potential for ventilative cooling strategies;
- Ventilative cooling in energy performance regulations;
- Design approaches and control strategies for ventilative cooling and case studies;
- Thermal comfort and ventilation;
- Coupling of ventilation with cooling systems;
- Ventilative cooling technologies such as multi-skin facades, ground coupled heat exchangers;
- IAQ impacts from outdoor sources;
- Acoustical issues from outdoor and indoor sources.
For airtightness related aspects:
- Infiltration measurement techniques and IR thermography;
- Durability of building and ductwork airtightness;
- Energy and IAQ impact of envelope and ductwork leakage;
- Design and construction approaches for airtight buildings;
- Risks related to airtightness;
- Optimal airtightness levels.
For ventilation in relation to IAQ and health aspects:
- IAQ impacts from outdoor sources;
- Possibilities and limitations of CO2 and other indicators for IAQ control;
- Humidity control and moisture damage;
- Ventilation in renovated buildings;
- Characterization of air cleaning technologies;
- IAQ aspects in ventilation regulations;
- Heat recovery issues (freezing, natural ventilation etc.).
Other aspects relevant to the conference include:
- Smart ventilation control and smart grids;
- Compliance schemes and barriers to innovation;
- Controls and user interaction;
- Fan energy use;
- Innovative ventilation concepts and combined systems;
- BIM (Building Information Modelling) and ventilation systems.
