28-29 March 2012, Workshop, Brussels - Achieving relevant and durable airtightness levels: status, options and progress needed

Adequate ventilation as well as good envelope and ductwork airtightness represent a specific challenge for new or renovated nearly zero-energy buildings. Alone, they can represent over 50% of a building's total space heating (or cooling) needs, and their share often increases with increasing energy performance.

This is the reason why many issues have arisen in the past few years regarding regulatory and voluntary initiatives to improve envelope and ductwork airtightness, bringing forward apparently simple questions such as:


30-31 March 2011, Workshop, Brussels -Full scale test facilities for evaluation of energy and hygrothermal performances

Ambitious targets on transforming the building stock into a highly energy efficient and low carbon environment demand also very performing scientific tools for the evaluation of the energy performance of improved building envelopes and construction techniques. Full scale testing becomes –again- more relevant, in combination with dynamic analysis and numerical simulation tools.


11-12 October 2010, Workshop, Brussels - Dynamic Methods for Building Energy Assessment

The workshop will highlight the Status, Classical approaches and New concepts covering areas where intelligent analysis techniques can be used for the following topics: 


14-15 June 2010, Workshop, Brussels - Large scale national implementation plans for building airtightness assessment : a must for 2020!

It is expected that many countries will between 2015 and 2020 have regulations imposing requirements for new buildings which are near-zero energy targets. This has major consequences:


18-19 March 2014, Workshop, Brussels - Quality of Methods for Measuring Ventilation and Air Infiltration in Buildings

There is a trend to perform more ventilation and air infiltration measurements in buildings, either to strengthen commissioning procedures or to learn from field data. This trend is stronger in nearly zero-energy buildings projects or programmes given the significant share of ventilation and infiltration losses on total building energy use.
